Supply three distinct, randomly generated 32–256-character ASCII tokens through

+

your secret-management environment: CROWDB_ICEBERG_READ_TOKEN,

+

CROWDB_ICEBERG_MANAGE_TOKEN and CROWDB_ICEBERG_CLEAR_TOKEN. Configure every

+

instance consistently. Management credentials can rename/initialize; only the

+

clear credential can replace the catalog. All three can read configuration.

+

The listener is plain HTTP: keep it on a trusted loopback/private hop behind a

+

TLS-terminating proxy. Do not transmit bearer credentials over public plain HTTP.

+

Set CROWDB_ICEBERG_TOKEN to the appropriate management token for CLI commands.

+

Each mutation takes a fresh UUIDv7 request identity. Preserve both that identity

+

and the exact arguments when retrying an interrupted command.

Status reports CatalogId, activation epoch, name and phase. Rename preserves the

+

CatalogId. The server validates dependencies and reconciles the root before

+

opening its listener. Ctrl-C stops admission and drains accepted connections.

+

Absent or empty warehouse selects the active catalog. A nonempty warehouse

+

returns 404 NoSuchWarehouseException. Unsupported endpoints return 406; all

+

table-format capabilities are false and HTTP idempotency is not advertised.

+

Clear makes the old domain inaccessible and selects a new empty catalog. It is

+

not physical erasure. Obtain the exact epoch and CatalogId from status, then

+

explicitly confirm both:

+
export CROWDB_ICEBERG_TOKEN="$CROWDB_ICEBERG_CLEAR_TOKEN"
+pixi run -- target/debug/crowdb-iceberg clear "$CLEAR_UUIDV7" empty \
+  "$ACTIVE_EPOCH" "$ACTIVE_CATALOG_ID"
+

Admission returns 503 during maintenance. Default persisted limits require an

+

11-second grace after the durable fence is observed. Restart cannot shorten it.

+

Another healthy instance resumes interrupted operations. An uncertain command

+

must be retried with its original identity and input, not a newly generated key.

+

Requests have a 24-hour retry window; expired identities are rejected. Bounded

+

ledger-slot collisions can reject new operations without evicting live receipts.

+

Run backend restart, two-instance and official-client checks with

+

pixi run -e iceberg-e2e test-pyiceberg-e2e. This uses a separate disposable runtime

+

registry and leaves persistent local cluster reservations intact.

Reading one unqualified -root, deriving identity from a display name, or synchronously deleting descendants -would create a hot key, make rename move data, and make clear unbounded. - -R177 defines one active catalog, a stable CatalogId, no tenant or warehouse in the -first milestone, and a lease-plus-grace clear boundary. This requirement builds the -library and service foundation on which all other Iceberg requirements depend. -The architecture boundary is [Native Iceberg Storage](../design/access-server/iceberge/design-crowdb-iceberg.md). - -## Solution - -- **CAT-I1 — Single active root:** one `ActiveCatalogRecord` is the only authority - selecting the visible CatalogId and activation epoch. -- **CAT-I2 — Stable domain:** display-name and configuration changes never change - CatalogId or descendant key prefixes. -- **CAT-I3 — Root publication:** initialize and clear publish visibility with one - compare-exchange; candidates not selected by it remain unreachable. -- **CAT-I4 — Admission fence:** every admitted request carries immutable CatalogId - and activation epoch context; clear completion follows R177's lease-plus-grace - rule. -- **CAT-I5 — Safe management:** initialize, rename, and clear are authenticated - CROWDB management operations, not Iceberg REST endpoints. - -1. Create feature-gated `lib/crowdb-access-iceberg` modules for `catalog`, `key`, - `record`, `operation`, `wire`, and `error`. Keep REST wire models, Iceberg domain - models, and versioned FlatBuffer storage records separate. Unknown key or value - versions, malformed IDs, and oversized values fail closed. -2. Reserve the binary `ICE\0`, key-version, and scope prefix. Separate the system - range for root, management operations/audit, and REST idempotency bindings from - half-open CatalogId resource ranges. Use big-endian fixed fields and binary-safe - length-delimited variable fields. System bindings carry bounded identifiers and - digests, not old resource response bodies; catalog-scoped records own those. -3. Store bounded `ActiveCatalogRecord` and `CatalogAuthority` values. The authority - holds display name, name/config generations, lifecycle, and the v1/v2/v3 - parse/read/create/write and upgrade capability matrix, but no child collection. -4. Implement idempotent initialize, epoch-checked display rename, and clear as - recoverable state machines in `catalog/repository.rs`. The root carries the - management operation identity and phase. Clear first CASes the old root into - maintenance, creates a new empty authority, then publishes its pointer by CAS - while retaining maintenance. Old lifecycle marking is reconciliation, not the - publication point. Before releasing maintenance, durably record publication and - the completed grace proof in the system operation. A later root replacement - cannot discard an unresolved operation reference; another server helps recover - it. Initialize uses the same recoverable publication receipt rule. -5. Add durable management request and audit records. Clear requires a distinct - privilege, exact active epoch, explicit confirmation material bound into the - request digest, and an operator-visible result. A retry with the same identity - and digest returns the original result even after subsequent clears. Authenticate - and verify the digest before replay; only a new operation checks the current - epoch. Bound retention, record size, and admission capacity independently; never - evict unfinished operations or unexpired results to admit new work. Management - identities contain a validated issuance time and have an explicit retry window; - expired identities are rejected rather than reused after result cleanup. -6. Add Iceberg server configuration and lifecycle wiring in - `app/crowdb-access-server/src/iceberg/`. Startup connects routed Chunk-KV and - chunk clients, validates the active root, and only then opens the separate - external Iceberg HTTP listener. Shutdown stops admission before draining - mutations and background work. -7. Implement the baseline `GET /v1/config`. Absent or empty `warehouse` selects the - active catalog; non-empty warehouse returns `NoSuchWarehouse`. The response - advertises only endpoints landed by later requirements and the exact v1/v2/v3 - capability matrix. It does not derive a REST prefix from the display name. - Publish `idempotency-key-lifetime` only when the retry contract below is active. -8. Do not introduce a global lock. Before R185, request admission reads the active - root authoritatively. R185 may add a bounded lease-qualified cache without - changing this contract. -9. Persist clear timing limits before entering maintenance. Let L be the maximum - root lease, Q the maximum request lifetime after admission, D the maximum - delegated credential lifetime, and S the clock-skew allowance. A conservative - completion deadline is maintenance observation time + L + Q + D + S; before - R185, L is zero. Persist that observation time only after confirming the durable - maintenance CAS. If a crash precedes timestamp persistence, recovery starts a - fresh conservative grace after observing maintenance; a pre-CAS preparation - timestamp cannot shorten the window. Lease age begins before reading the root, - so delayed replies cannot extend it. Without a root cache, the request's Q - deadline starts before its authoritative root read; a delayed reply past that - deadline cannot admit old-context work. Requests and credentials inherit absolute - deadlines; no renewal or chained - delegation extends old-context access. Enforce expiry at response/stream and - FileIO boundaries, not just HTTP admission. Resume uses persisted bounds, never - shorter current configuration. Clock uncertainty fails closed. Ordinary - authoritative admission returns 503 during maintenance; leased admission may - continue only until expiry. Open the new domain after the grace proof, then - finalize the management result. Durable GC pins remain a separate R183 fence. -10. Implement the shared REST retry boundary in `operation` and `wire` now, for R179 - to consume. Accept the OpenAPI's optional UUIDv7 `Idempotency-Key`; validate - issuance time, clock skew, and the advertised reuse window. Atomically bind a - key in the system scope to authenticated principal, route/action, canonical - request digest, CatalogId, and activation epoch before domain mutation. Keep it - at least for the advertised lifetime from first submission plus grace. Reuse - with different input fails without mutation; another principal cannot inspect - the result. Check active context before replay: a retired binding returns a - non-disclosing conflict and cannot be rebound to a new catalog. Persist and - replay 200/201/204 and deterministic terminal 4xx, including 409; never finalize - 5xx. Unknown mutation outcomes retain recoverable state and resume before any - new attempt. Without a client key, allocate an internal recovery identity but - do not promise deduplication across separate HTTP requests. Retain backend - request identities and exact mutation input through outcome resolution; the - bounded Chunk-KV retry cache alone is not the application retry ledger. -11. Supply management authorization, audit persistence, and the common Iceberg - authentication/admission boundary with this foundation. Existing S3 SigV4 - wiring is not an Iceberg bearer/OAuth implementation. R184 extends and verifies - this boundary rather than supplying security for already-exposed endpoints. - -## Dependencies - -- Depends on R177, routed Chunk-KV compare-exchange and scans, stable request - identity, and Access Server configuration. Produces Iceberg authentication, - management authorization, and audit integration before exposing its endpoints. -- Produces CatalogId, activation epoch, key/value envelope, service lifecycle, and - capability types consumed by R179 through R185. -- Old-catalog physical cleanup is R183. Before R183 lands, retired domains remain - unreachable but are not erased. -- Cache fanout is R185. Before it lands, authoritative root reads preserve correct - behavior at higher latency. - -## Acceptance - -- Given an empty root and concurrent initialize requests, when all instances publish - candidates, assert exactly one active pointer wins and same-identity retries - return that result.

Do not silently +grant mutation rights or conflate daily data access with administrative authority. +The independently testable model and storage foundation is complete; resume the +remaining mutation/retry/HTTP work after this public privilege decision.

It does not verify spec membership, summaries, + referenced file existence or snapshot-wide lineage. The list writer version is + explicit; do not infer it from the current table version. +- `src/file/multipart_credits.rs`: durable global session/reserved-byte admission + with a single pending CAS journal; `settle` repairs uncertain reservation or + terminal release. `MultipartRecovery` helps that journal before scanning four + sessions. Call admission before exposing an upload; low-level repository test + fixtures can still be uncredited.

Keep the approved deferral and physical + deletion disabled; this is not a cleanup job that can safely use only TTL. +- **High: remaining FileIO semantics (R180)**. Collection schemas, equality IDs, + partition/metric validation and snapshot-wide DV/row-lineage checks require + bounded traversal plus table context. The difficult scalar bridge is now landed: + typed IDs/paths, v1/v2/v3 inheritance, atomic failure behavior and cross-block + state have focused tests. Next implement bounded collections; do not rebuild + the Avro parser or conflate scalar validation with full manifest acceptance. +- **High: multipart/HTTP composition (R180)**. Durable credits, parts, completion, + publication and recovery primitives exist. Wire official retry/error/XML + behavior, authentication/limits and semantic sealing onto those same fences. + Invalid frozen selections and uncertain publication must not acquire a second + HTTP-only state machine. Standard PUT semantic kind still needs the R177 choice. +- **High: namespace/table races (R179/R181)**. Create/rename-in versus namespace + drop needs shared admission and crash recovery; bounded table heads, logical + drop and purge intent are still prerequisites. Preserve the separate namespace + latency blocker instead of weakening its acceptance fixture. +- **Medium, good bounded follow-ups**: metadata projection pages with canonical + fallback; multipart response serialization and LastModified once their contract + is read; grant/byte-limit intersection tests; additional negative format fixtures. + Take one small verified slice per commit. None alone completes a catalog server. +- **Broad integration cost (R184)**: official FileIO/REST clients, cancellation, + native restarts and engine/version matrices. Start foreground vertical slices + as lifecycle/commit features land; GC-dependent acceptance remains last. Release + engine profiles and no-GC capacity policy remain human choices in R177. + ## Review checkpoint - R178 supplies catalog management, authentication, recovery, and config.

Candidate admission also - compiles the confirmed SDK-safe name-mapping profile into segmented Parquet paths. - Files: `src/commit/evaluator.rs`, `src/commit/evaluator/`, and - `src/table/metadata/name_mapping/compile.rs` in `crowdb-access-iceberg`. - Twenty-two focused tests pass, including generated Java 1.11.0 v1/v2/v3 - differential schema/layout/property fixtures and raw-number preservation. - Complete library tests passed before the final focused additions; final focused - tests and workspace `rs-fmt-check` / `rs-lint` pass. No HTTP writes are enabled. - Keep this item open for broader SDK differential coverage and integration with - file proofs: `EvaluatedMetadata` is explicitly not a publishable proof. -- [ ] **Commit file proof**: bind candidate snapshots and canonical file resolution - to the selected generation, including reused-manifest provenance after schema - expiration and prior-delete preservation. Structural metadata is not this proof. - Implemented checkpoint: bounded checksum-validated DV position ranges and - direct-parent snapshot DV replacement checks. Both snapshots undergo complete - selected-file validation; surviving data retains immutable identity, sequence - and partition bindings. Replacements cover prior DVs and applicable position - deletes, including canonical Java SDK Parquet pages; removed data may drop its - DV, but candidate orphan DVs fail. Aggregate candidate ranges and each prior - vector are independently bounded. This is not the generation-bound publication - proof: complete publication admission remains to compose. Equality-delete - rewrites and position-delete removal without a replacement DV are not proven - by this helper. Files: `file/deletion_vector/positions.rs` and - `manifest/snapshot_validation/preservation.rs` in `crowdb-access-iceberg`. - Verification: eight new focused tests cover range encodings, CRC, budgets, - exact-target coverage, dropped/replaced DVs, immutable identity and SDK v1/v2 - Parquet page fixtures. Complete library tests and workspace fmt/clippy pass. - Prior-generation provenance checkpoint: `commit/provenance.rs` builds a bounded - exact immutable-manifest index only from retained canonical lists in a selected - head. Recovered writer contexts may include schemas already expired from table - metadata; unrelated uploads cannot authorize themselves. List EOF, manifest - framing/digest EOF, declared length/spec/content, catalog epoch and complete head - fences are checked. Four focused tests cover recovery, unselected uploads, - independent limits, corruption, stale heads and head changes during reads; - workspace fmt/clippy pass. - Candidate composition checkpoint (2026-09-24): `CandidateFileSource` fences - both prior head and candidate successor identity. Prior-reachable manifests may - recover expired definitions; new uploads must match candidate definitions. - Embedded v1 snapshots now enumerate canonical manifests without fabricating a - manifest-list file, enforce actual v1 writer headers, and participate in the - prior provenance index. All candidate snapshots undergo writer validation and - current-schema Parquet projection; new children invoke direct-parent DV checks. - Retained context composition preserves historical fields, uses one work budget, - and permits a dropped partition source only for the void transform. Exhausted - definition IDs no longer prevent reuse of existing schemas/specs/sort orders. - Auxiliary references now bind exact canonical file length, Puffin total footer - size and blob descriptors, including the spec-permitted property subset; file - counts, full canonical bytes and descriptor comparison work have separate caps. - Partition statistics currently receive Parquet container validation only, not - unified partition schema, ordered rows or count semantics. These helpers remain - explicitly separate from a publishable proof, and no HTTP writes are enabled. - Files: `commit/files/`, `commit/provenance/scan.rs`, - `manifest/snapshot_reader/references.rs`, `table/metadata/context.rs`. - Verification: all 471 library tests and workspace fmt/clippy pass, including - legacy enumeration, current-reader projection, provenance races, auxiliary - descriptor corruption, independent budgets and exhausted definition IDs. - Next integration sequence: finish selected-use semantics and aggregate admission, - then produce a non-forgeable generation-bound publication proof. - Only after that wire the operation journal, immutable metadata write and head CAS. -- [ ] **Create and atomic publication**: compose durable request identity, - namespace reservations, immutable candidate writes, one head CAS and recovery; - cover immediate/staged create, concurrent losers and response-loss replay. - Do not enable HTTP writes before the preceding proofs and crash tests pass. - Update-journal checkpoint: `TableCommitOperation` stores the exact input head, - request payload digest, principal, evaluation timestamp, candidate head and final - response payload. Its separate FlatBuffers union tag and key scope are appended, - preserving all existing wire values. `TableCommitJournal` CAS transitions freeze - the selected generation and candidate; retries recover the original intent, - never rebase. Publication outcome transitions require observing the exact - candidate head or a definitively superseded input fence. Unknown outcomes cannot - become rejection merely due to timeout. Context checks bracket durable reads and - writes. The journal itself does not validate files or publish table heads. - `evaluate_durable_commit` now reads only the journaled request payload and exact - canonical input file, uses the persisted evaluation clock, and rechecks both - phase revision and complete head after evaluation. Recovery must reproduce the - frozen candidate digest/identity byte-for-byte; caller-supplied altered targets, - timestamps and stale generations cannot silently rebase or write candidates. - Verification: 478 library tests, 48 access-server tests with `iceberg` enabled, - workspace fmt and clippy pass. Seven journal/preparation tests cover phase reply - loss, terminal replay, abort/publication arbitration, candidate/head binding, - retired epochs and deterministic canonical reconstruction without candidate writes. - Update-publication implementation: `prepare_table_commit` composes durable - evaluation, selected-generation provenance, all retained snapshot checks and - auxiliary bindings into a privately constructed `PreparedTableCommit`. The - proof owns its storage domain; callers cannot transplant it into another store. - Journal advancement is internal, with a `test-util` hook only for phase tests. - Publication freezes the candidate, writes immutable inline/chunked metadata, - selects generation plus one with one head CAS, persists the exact response and - only then clears the pending marker. Recovery preserves FileId/tree identity - after a lost authority write, reconstructs interrupted chunk writes, resolves - unknown head-CAS outcomes, and durably rejects superseded input without rebasing. - Six focused tests cover concurrent winner/loser, every durable reply-loss point, - marker settlement, stale prepublication recovery and chunked candidate failures; - all 484 library tests, 48 Iceberg-enabled access-server tests and workspace - fmt/clippy pass. - Publication deliberately rejects nonempty partition-statistics while their - selected-use schema/row validator is unfinished; it does not promote the current - container-only auxiliary helper into a complete proof. Plaintext Parquet remains - the enabled data/delete profile; ORC and physical reclamation stay deferred. - Remaining: full proof-profile coverage, immediate/staged creation, namespace - admission/recovery, request admission/retry-ledger composition and REST wiring. - No endpoint or advertised capability changed. - Initial-create evaluation: `CreateTableRequest` and `evaluate_table_creation` - now construct deterministic empty-table metadata from a retained identity and - timestamp. Fresh IDs follow Java's sibling-first struct traversal, list element - allocation and map key/value allocation; identifier IDs, nested defaults and - partition/sort sources follow the same rebinding. Default format/compression, - reserved-property filtering, retry properties, metrics column aliases and - SDK-serialized null optional fields are covered. The pure candidate is explicitly - not a namespace/publication proof. Generated Java 1.11.0 requests and complete - v1/v2/v3 output documents provide differential fixtures. - Verification: all 493 library tests and workspace fmt/clippy pass, including - eight focused initial-metadata tests and the complete-document SDK comparison. - Next creation slices: persist a separate table-create intent; reserve the name - before parent admission; write and verify initial immutable metadata before - taking the parent marker so namespace recovery does not need a block-store - dependency. Extend parent marker dispatch and namespace table probes to resolve - table-create reservations. Publish the first head and mapping, then settle both - markers only after the durable result. Staged creation retains a draft and expiry; - final-commit binding and expiration compete through a phase CAS, never TTL-delete - an uncertain publisher. Cover every durable reply-loss point and drop races. - Immediate-create implementation: `TableCreator` persists a dedicated - `TableCreateOperation` with input, canonical document, fixed head and response. - Its appended wire tag/key scope preserve earlier values. The phase journal - freezes identities and parent snapshots. A name reservation precedes immutable - metadata writes and parent admission; selected head, published mapping and - terminal response precede conditional marker cleanup. Namespace drop and marker - dispatch now help table creation without needing block IO after admission. - Staged-create execution remains explicitly disabled; pure staged metadata is - not a staged publication implementation. HTTP writes remain disabled. - Focused verification covers every durable creation reply-loss point, chunk - write failure, same-name competition, retired catalog replay, and namespace drop - at every interrupted phase plus an actual parent-CAS race. One uncovered drop - preflight assumed all parent markers were namespace operations; its dispatcher - now recognizes table creation before fencing instead of reporting corruption. - Gates: 502 library tests, 48 Iceberg-enabled access-server tests, protocol - all-target tests and workspace fmt/clippy pass. No unsafe scope or lock was added. - Staged compatibility inspection: Java `RESTSessionCatalog.createChanges` sends - assign-UUID, upgrade, full schema/spec/order setters, location and properties; - `RESTTableOperations` prepends these to transaction changes with `assert-create`. - `CatalogHandlers` applies that list to an empty builder, not to the draft as an - ordinary next-generation update. Implement this distinct evaluator path and use - standard UUID/location fields to find and bind the durable draft; do not require - a nonstandard SDK token or renumber staged file schemas a second time. - Initial-commit evaluator checkpoint: `evaluate_table_create_commit` now applies - assert-create requests to an empty builder, preserves staged field IDs and - requires explicit UUID/location/definition initialization. It produces generation - one without a draft metadata-log entry. The first format upgrade selects the - initial builder version, matching Java's handler. Six focused tests cover - incomplete initialization, identity/requirement rejection, independent budgets, - malformed auxiliary metadata and complete v1/v2/v3 SDK output comparison. - Fixtures invoke the pinned SDK's real `RESTSessionCatalog.createChanges` and - append snapshot/ref transaction updates. All 508 library tests and workspace - fmt/clippy pass. Durable staging, expiry and its final file-proof/publication - integration remain unfinished; this evaluator does not grant publication. - Initial-file isolation checkpoint: candidate resolution now distinguishes a - selected prior generation from an exact reserved create operation. Creation - checks the journal, name reservation and absent head before/after resolution; - it cannot borrow expired definitions from a fabricated prior generation. - Initial snapshots use the same bounded file/projection checks and validate - parent-child delete preservation within the candidate. Empty auxiliary lists - still check authority. Four focused tests cover real manifest/Parquet files, - missing schema/parent, stale intent during IO, reservation/head/catalog fences, - wrong candidate/phase and work overflow.

The live server still installs - neither table reads nor writes. Runtime catalog admission uses zero delegated - grace by default, so credential activation must audit persisted clear/request - bounds rather than merely advertise the new routes. - Absolute connection lifetime now covers streamed responses and completion - heartbeats, not only handler execution. FileIO and REST both check the listener - lifetime against persisted request bounds. Runtime initialization uses a - five-minute request bound; old catalogs retain their original shorter bound. - Credential vending remains disabled pending the delegated-grace audit. - `FileDelegationLimits::issue` now requires the matching Ready catalog authority - and checks its persisted delegation bound independently of issuer configuration. - Zero-grace catalogs cannot mint credentials; wider signing configuration cannot - bypass the bound. HTTP callers must still reauthorize the current root and exact - table/draft, and runtime delegation bounds remain disabled until that wiring. - Verified: 49 server feature-enabled tests, workspace fmt/clippy and explicit - Iceberg-feature clippy.

At most 10,000 entries - occupy 420,007 encoded bytes; each work step verifies that bounded selection and - one selected part, copies one configured byte window and CASes its checkpoint. - Four tests cover maximum selection framing, missing/changed parts, abort, invalid - work limits and lost replies at selection and every progress boundary across - repository instances. The assembled tree remains private pending semantic - sealing; this does not implement the final HTTP Complete response or publication. - A four-session recovery scan now settles one pending part mutation or performs - one assembly byte window per visit. Expired open/completing sessions are logically - aborted after pending part mutations settle; parts and checkpoints remain intact. - Finished assembly is reported as awaiting semantic sealing, not as published. - Four sweep tests cover multi-page progress, cross-instance visits, exact expiry, - retained bytes, invalid/foreign cursors and corrupt pages before any mutation. - Each native listener now runs the multipart sweep alongside namespace recovery. - Per-session time budgets use the persisted catalog request bound; a timed-out - session is deferred without preventing later entries in the same page. The - outer page budget bounds scans and context checks; context changes reset cursors. - Two additional tests verify timeout limits and that a blocked first part read - cannot starve a later session's expiry or persist unfinished assembly bytes. - A caller-provided sealed record is now frozen as an immutable payload before - the publication phase CAS. Recovery replays the exact seal through immutable - file publication and records the selected FileId, including an existing equal - file's original identity. A proven unequal immutable location records a terminal - Conflicted phase; ambiguous storage/context failures remain recoverable instead. - Five publication tests cover all five lost-write boundaries, restart replay, - equal/different locations, abort races, corrupt intent and lost conflict replies. - This does not infer HTTP file kind or replace canonical format validation. - Native part listing now reads one upload-scoped storage page of at most 256 - records, using numeric part markers and preserving gaps. A requested maximum up - to 1000 may return a smaller truncated page. Session checks bracket the scan; - pending mutations, expiry, terminal phases, stale snapshots and corruption fail - closed rather than returning mixed part state. Five tests cover pagination, - independent limits, adjacent uploads and a session mutation during the scan. - Part mutation now persists `modified_ms` in the FlatBuffers part record. The - repository stamps it from the accepted mutation time, including replacement; - lost-write replay retains that value. List decoding rejects zero or out-of-session - timestamps before XML serialization. Existing pre-field part records decode with - a zero timestamp and fail closed; there is no public multipart endpoint or - deployed compatibility promise for those experimental records. - Global admission now persists independent session/byte limits and one bounded - CAS journal. A session reserves its staged-byte ceiling before authority creation; - only terminal sessions release it, retaining a policy/sequence-bound receipt. - Recovery helps a pending precreation journal before scanning and later returns - terminal credits, without deleting parts or introducing process-local locks. - Nine model/record/driver tests cover separate limits, every create/release lost - write, concurrent admission, policy mismatch, duplicate release and stale helpers. - Public HTTP admission/configuration remains to be connected. Capacity of retained - physical orphans remains the separate R177 trial-policy decision. -- [x] **Multipart response encoding**: the server now has bounded S3-shaped - Create/List/Complete success XML and typed error XML; UploadPart returns a - quoted SHA-256 ETag header, ListParts emits the same ETag, LastModified from - persisted part time, exact requested MaxParts and continuation marker. Complete - requires a Published session, matching FileRecord and a caller-supplied HTTP - object URL. XML text is escaped; abort returns 204. Six server tests cover XML - escaping, pagination, dates, errors and incomplete publication. Files: server - `file_response.rs`, library multipart model/codec/repository/list, protocol schema, - library/server tests. HTTP dispatch/official client use still await composition. -- [x] **Grant and byte intersection**: `FileTransferAdmission` checks a verified - grant's operation, table, principal, upload ID, validity window and active - multipart credit against configured service and durable session ceilings. - `check_create` preflights the global policy and session budget before the caller - performs `MultipartAdmission::reserve`; `receive` and `read_body` enforce - intersected declared and actual stream/range bytes before publication or read. - Three focused server tests cover each limit, foreign scope, missing/released - credit, expired grant, upload backpressure and bounded range reads. Files: - server `file_admission.rs` and server tests. Public listener routing and - credit-reservation wiring still await complete HTTP composition. -- [x] **Projections**: generation-local bounded derived JSON pages and canonical - fallback on every invalid projection. Files: metadata projection modules/tests. - `ProjectionStore::put` derives raw top-level JSON children from already sealed - canonical bytes; SHA-256 must match the authoritative FileRecord. Optional - construction is capped at 2 MiB, 64 children and 1024-byte field names. Larger - metadata remains readable through the ordinary bounded canonical stream. - Scope 14 keys bind catalog/table, generation, JSON digest, projection version, - child and page. A checksummed root (at most 32 KiB) describes deterministic - children; their exact JSON bytes occupy immutable pages of at most 32 KiB. - Child digests and exact page sizes are checked before selected bytes escape. - Children publish before the root; failures return false and cannot gate file - publication. Lost-write retries converge through immutable compare-exchange. - `select` returns bounded selected child bytes only after all requested children - verify; absent, corrupt, wrong-identity/version, oversized or unavailable required - projection records return a fresh canonical FileReader. An empty selection - always streams the byte-identical complete file. Invalid canonical records and - corruption encountered during fallback remain errors. Hits do not probe unused - canonical blocks; unrequested children are not read. - Ten focused tests cover multi-page values, exact whitespace, no canonical block - reads on hits, identity/version bounds, every missing/corrupt page, unavailable - storage, write-loss replay, oversized inputs/records and malformed keys. - Load/commit integration still belongs to R181/R182: callers must supply the - selected generation's authenticated FileRecord and consume fallback streams. - This is not a whole-file materialization path or full metadata semantic validator. -- [ ] **Format validation**: bounded Avro blocks, v1/v2/v3 inheritance and row IDs, - deletion vectors and fixed-size Parquet/ORC/Avro/Puffin hints. Files: format - validation/probing and streaming fixtures. - Canonical Parquet and Puffin framing probes now derive bounded footer locations - without trusting stored hints or allocating advertised footer sizes. They check - magic, signed Puffin lengths, reserved flags and cross-leaf reads. Four tests - pass; this is not footer decoding, semantic validation or complete file sealing. - Puffin footer reading now bounds both encoded and decoded metadata to at most - 1 MiB, caps blob/field/property collections and rejects duplicate properties, - overlapping or escaped blob ranges and invalid deletion-vector descriptors. - Plain JSON and one sized LZ4 frame are supported; concatenated/truncated frames, - bad checksums and expansion beyond the output ceiling fail closed. The existing - LZ4 dependency's frame feature supplies checksum verification. Four tests cover - canonical reads, compression, resource caps and exact manifest-to-footer - offset/length/referenced-file/cardinality matching. - Deletion-vector validation now re-reads the canonical descriptor and streams - portable Roaring arrays, bitsets and runs without collecting deleted positions. - It validates lengths, magic, CRC-32, ordered keys, container offsets, signed - 64-bit position bounds and exact cardinality. One bounded container directory - and a 16-KiB input frame suffice; independent blob/bitmap caps bound work. - Four tests cover each container family, boundaries, corruption with valid CRCs, - descriptor count mismatch and resource caps. Snapshot-wide uniqueness, matching - actual data-file row counts and commit/sealing integration remain pending. - ORC probing reads at most 255 postscript bytes and validates protobuf framing, - footer/metadata spans and optional postscript magic. Three additional tests cover - unknown fields, legacy header magic, maximum size and malformed wire inputs. - Avro OCF framing now pulls one encoded block at a time with independent header - bytes, metadata entries, encoded block bytes and record-count limits. Positive - and sized negative metadata maps, sync markers, overflow and cancelled readers - are checked across leaf boundaries. Null and raw-deflate codecs now enforce an - independent decoded-byte cap and reject truncated or concatenated streams. - Writer-schema binary layouts now compile to bounded graphs with named recursive - references. Decoded validation checks primitive widths/UTF-8, unions, enum indexes, - exact collection byte counts and complete block consumption without retaining - datum graphs. Independent schema-byte/node/edge and datum-depth/work limits reject - even zero-byte recursive or huge null collections. Six layout tests pass. - `AvroRecords` compiles the container's own schema once and validates one decoded - block per pull; two integration tests verify corruption, bounds and cancellation. - Root scalar projection now selects at most 64 int/long/string fields by Iceberg - field ID, not writer names/order, and borrows strings from one decoded block. - Nullable unions work in either branch order. Every skipped field still receives - binary validation under the same block-wide work/depth limits; malformed IDs, - duplicate IDs, missing selections and trailing bytes fail closed. Four cursor - tests pass. Optional selections preserve absent values as unknown, and selected - writer types are exposed before reading any records. Typed manifest-list pulls - now validate canonical same-table locations, positive lengths, spec IDs, - sequence ordering, version-dependent required/unknown counts and v3 delete/data - row-ID separation. Four tests cover renamed/reordered fields, missing/null - values, empty-list schema types and poisoned cursors. Partition-summary semantics, - table spec membership and complete collection/cross-file semantics - remain separate; list decoding does not yet prove those cross-file invariants. - Nested scalar paths now traverse records and nullable records, with at most 64 - selections, 16 IDs per path and 16,384 compiled field visits. Shared named record - layouts cannot expand the projection without a bound. Selected and skipped - fields share one block-wide work/depth budget; null parents clear child slots - without retaining prior-record values. Four nested tests pass. Array/map semantic - projection is not implemented; their binary layout is still fully validated. - Reader-schema resolution, logical/manifest field semantics and optional codecs - remain separate; this does not advertise complete manifest v1/v2/v3 validation. - A constant-state manifest inheritance resolver now handles v1 zero sequences, - added-only sequence inheritance, explicit ages, upgraded existing-file row IDs, - data/delete separation and checked row-ID advancement. Five semantic tests pass. - Typed scalar entry projection now connects Avro decoding to that resolver and - preserves its state across blocks. Required values, path scope, format/content, - DV descriptor bounds and row-ID overflow fail before advancing the failed entry. - Five entry tests and two chunk-backed null/deflate block integration tests pass. - Partition/equality-ID/metrics semantics, canonical DV reference verification and - table commit admission remain pending; this is not full manifest validation. -- [ ] **Acceptance**: official FileIO, real chunks/restarts, concurrency/lost - responses, all boundary tests; run fmt and lint independently. No full feature - advertisement or closure until the complete requirement passes. - -## Files And Verification - -- Library: `lib/crowdb-access-iceberg/src/{file,record,metadata_projection}/`. -- Protocol: `lib/crowdb-protocol/src/fbs/iceberg.fbs` and generated module. -- Server: `app/crowdb-access-server/src/iceberg/` and integration tests. -- Unit: exact location round trips, rejected aliases/escapes, byte boundaries, - key binding, codec corruption, range parsing and immutable publish conflicts. -- Integration: bounded stream retention, real chunk range crossings, lost replies, - multipart recovery, projection fallback and format block boundaries. -- E2E: pinned official clients using only delegated immutable operations; general - S3 metadata remains isolated. Preserve the separate R179 latency blocker. -- Gates: `pixi run -- cargo test -p crowdb-access-iceberg --all-targets`, affected - server/protocol tests, `pixi run -- cargo fmt --all -- --check`, `pixi run rs-lint`. - Prefix server-spawning tests with `pixi run clean-env &&`. - -## Verified Checkpoint - -- The earlier 230-test library checkpoint covered namespace, file records, range/streaming, - credentials, JSON, format framing, Avro blocks/codecs, manifest inheritance, - digest/writer checkpoints, staged assembly and multipart models/records. - Focused native request authentication, pull-body and request parsing tests pass - with Iceberg enabled and the general S3 listener feature disabled. -- Native file-tree publication, full read, a range crossing leaf boundaries and - Chunk-KV restart pass against real ChunkDB/DiskIO using the separate - `iceberg_file_storage_test` target. This verifies storage bytes, not Parquet - semantics or the pending FileIO HTTP and official-client contract. - The same native fixture now persists a multipart reservation, settles it through - the recovery scan, freezes its selection and checkpoints seven assembled bytes. - After Chunk-KV restart and a new chunk client, recovery completes the exact bytes - while the file location remains unpublished. Logical abort retains that state. - The expanded fixture passes in 35.96 seconds; Iceberg E2E-feature clippy passes. - The fixture also starts the actual Iceberg listener and observes it settling - and aborting an expired pending upload without client recovery calls. The first - attempt exposed a synthetic root with no management journal; initialization now - uses the real management repository. The expanded fixture passes in 35.92 seconds. - It now admits the expired upload through durable global credits and observes - the real worker settling its part, aborting, releasing credits exactly once and - retaining its part authority. The expanded fixture passes in 37.40 seconds. -- Command: `pixi run clean-env && CROWDB_RUNTIME_ROOT="$PWD/.crowdb-runtime/ephemeral/iceberg-file-storage" pixi run -- cargo test -p crowdb-access-server --features iceberg-e2e --test iceberg_file_storage_test -- --nocapture`. - -## Handover — 2026-09-23 - -The initial handover boundary was typed scalar manifest-entry decoding plus -cross-block inheritance. Subsequent work added bounded equality-ID list decoding, -schema element-ID checks, typed OCF manifest metadata, bounded metric maps, -historical context, typed partition/bound semantics and a bound streaming reader. This is not requirement -completion or a new blocker. -No user-guide edits, public FileIO exposure, new unsafe exceptions, locks or -physical deletion were added. Resume with the next task below, not a rewrite of -the landed storage primitives. The broader ordering is in -`plan-iceberg-functional-catalog.md`; human choices remain in R177. - -### Immediate continuation - -- [x] **Typed scalar manifest entries**: implemented `src/manifest/entry.rs`, - `entry/decode.rs` and `tests/manifest_entry_test.rs`, reusing `AvroProjection::paths`, - `AvroFieldPath { ids, required }`, `field_types()` and `ManifestInheritance`. - `ManifestEntryState` owns inheritance across blocks and rejects a mismatched - projection version/table. Root IDs are status `0`, snapshot `1`, data-file record `2`, data sequence `3`, - file sequence `4`. Nested paths include `[2, 134]` content, `[2, 100]` path, - `[2, 101]` format, `[2, 103]` record count, `[2, 104]` byte length, - `[2, 140]` sort order, `[2, 142]` first row ID, `[2, 143]` referenced file, - `[2, 144]` DV offset, and `[2, 145]` DV size. The v1 deprecated block-size field - `[2, 105]` is also required. Types are checked at compile time and required values - at pull time. Paths bind to the native table; no extension-based kind guessing. - Scalar/binary failures and inheritance errors never advance that entry's row IDs. - Position deletes ignore sort order. Puffin entries require v3 position-delete - content, a referenced file and an in-file offset/size pair. Full equality-delete, - partition and metric semantics are explicitly not asserted by `ManifestScalarEntry`. - When adding those checks, perform them before `inheritance.resolve`, not after - yielding the entry. Five tests cover versions, malformed values, null records, - explicit versus inherited row IDs, overflow, descriptors and poisoned cursors. -- [x] **Bounded equality-ID lists**: array projection now retains `element-id` - and exposes a validated encoded integer list. The manifest entry projection - requires element ID 136 when field 135 exists. Equality deletes require a - nonempty list of at most 4096 positive, unique IDs; other content rejects a - non-null list. Positive and sized negative Avro blocks, over-limit lists, - wrong schema IDs and inheritance-safe failures have focused tests. Membership - in the table schema and presence in the delete file still need table/file - context; this is partial collection validation. -- [x] **Typed manifest writer metadata**: `ManifestMetadata::parse` reads bounded - OCF properties, derives the writer's v1/v2/v3 version and data/delete content, - requires version-specific schema/spec IDs and checks the bounded schema and - partition-spec JSON roots. It rejects mismatched schema IDs. The existing - chunk-backed, two-block stream fixture now carries and parses real OCF manifest - properties before constructing inheritance state. Table schema/spec membership, - nested JSON semantics and full list-to-manifest consistency remain. -- [x] **List/header inheritance context**: `ManifestEntryState::from_list` checks - same-table location, content and available partition-spec ID before using the - list's snapshot, sequence and row-ID sources. A v1 manifest can still use a - newer enclosing list; missing optional v1 spec ID cannot be compared. Exact - list location/length to opened file identity and table schema/spec membership - remain for full cross-file validation. -- [x] **Bounded metric maps**: integer-keyed Avro logical maps now require exact - key/value field IDs and non-null integer keys with long/bytes values. Selected - values borrow validated block bytes; `AvroMetricMap::visit` independently caps - items and encoded bytes. `ManifestMetrics` owns at most 4096 entries and 1 MiB - of value payload across all six maps per entry. Duplicate/nonpositive keys, - negative counts, null-plus-NaN count overflow/excess, malformed block framing - and wrong types/IDs fail before inheritance. Nested counts may exceed file row - count. Null and empty maps remain distinct. Six new tests and expanded - null/deflate, cross-leaf/block fixtures pass. No locks or unsafe were added. - Numeric interpretation of binary bounds and schema membership remain dependent - on typed table context; these maps alone do not establish full metric semantics. -- [x] **Historical schema/spec context**: `ManifestContext` indexes nested IDs, - required ancestry and collection ancestry, validates primitive parameters and - version gates, and derives partition transform result types. Limits: 1 MiB JSON, - 32 nesting levels, 4096 fields and 256 partition fields. v1 missing partition IDs - use sequential IDs from 1000. Header definitions bind to trusted historical - schema/spec definitions, not current table IDs. Optional trusted schema history - retains dropped metric/equality columns under independent history/work/byte caps. -- [x] **Partition tuples**: `AvroTuple` retains writer logical annotations and - validates required parent records, exact tuple IDs and bounded values. - `ManifestEntryProjection::with_context` checks logical types, decimal fixed - precision/scale, timestamp zone/precision, nulls, bucket/truncate domains and void. - Unknown transforms preserve bounded values without asserting filtering semantics. - Tuple failures precede inheritance, including null unpartitioned records. -- [x] **Typed metrics/equality semantics**: the contextual projection validates - retained column IDs, NaN applicability and equality-field eligibility, including - collection ancestry. Bounds check encodings and ordering for scalar types and - geospatial points, including numeric promotions, signed decimals, signed zero, - UTF-8 and geography dateline wrapping. Position-delete reserved columns are - recognized. Variant bounds now use the bounded object decoder below. -- [x] **Partition summaries (task 3)**: decode bounded field-summary arrays by - field ID, bind ordering/types to the historical partition spec, and check - summary flags and bounds against streamed entries before reader completion. - Cover null/NaN, signed zero, malformed layouts, limits and poisoned cursors. - `ManifestListEntry::partitions` preserves absent/null/empty arrays. Each list - record admits at most 256 summaries and 1 MiB encoded summary bytes. - `ManifestReader` checks bound containment for all entry statuses and exact - null/known-NaN flags at EOF; unknown transforms retain bounds without using - them for filtering. Four new tests plus the full library gate pass (277 tests). -- [x] **Variant bounds (task 4)**: validate bounded concatenated Variant metadata - and primitive-valued bounds objects, normalized paths, paired types and order. - `entry/variant.rs` and its `primitive`/`path` children accept metadata v1, - all offset widths, unordered value storage and optional one-sided paths. - Limits are 1 MiB encoded bytes, 4096 dictionary/object entries, 4096 path bytes - and 32 path segments. Same logical types compare exactly, including integer/ - decimal encodings and micro/nanosecond timestamps; float/double and timestamp - zones remain distinct. Null/NaN bounds, nested object/array values, malformed - offsets, duplicates and unsupported type IDs fail before inheritance advances. - Five focused tests and the full library gate pass (282 tests). - Encoding reference: [Parquet Variant](https://github.com/apache/parquet-format/blob/master/VariantEncoding.md); - path reference: [RFC 9535 normalized paths](https://www.rfc-editor.org/rfc/rfc9535.html#section-2.7). -- [ ] **Remaining format semantics**: full default-value validation, - encryption key metadata and split offsets remain. - Actual data/delete-file field presence and true bounds against data require - format/file context. No complete manifest/seal acceptance is claimed here. -- [x] **Scalar block integration**: `manifest_entry_stream_test.rs` composes - `AvroRecords::next()` with a projection per decoded block and shared - `ManifestEntryState`. Tests cross 64-byte stored leaves and Avro block boundaries - for v1/v2/v3 with both null and raw-deflate codecs; a binary-valid but semantically - invalid later block leaves prior row-ID progress unchanged. Drop the borrowed - projection before the next mutable reader pull; no unsafe/self-referential state - is needed. `common/manifest_entry.rs` provides typed schema and OCF datum fixtures. - These use the test block store, not a new real-ChunkDB process acceptance run. -- [x] **Bound manifest reader**: `ManifestReader::open` binds exact native location, - length, kind/format, parsed header and trusted schema/spec context. `next_entry` - retains one decoded block, checks added/existing/deleted counts and rows, live - minimum sequence and sequence ceilings. EOF is required before `is_complete`. - Cancellation/errors poison the reader; reopening canonical bytes starts fresh. - Candidate inheritance is installed only after semantic and list-total checks. - Tests cover v1/v2/v3, null/deflate, 64-byte leaves, multiple records per block, - multiple blocks, bad later entries, wrong identity/spec, totals and cancellation. - These are chunk-backed library tests, not new real-server or client E2E acceptance. -- [x] **DV cross-file validator (task 5)**: `SnapshotDvValidator` connects live - manifest entries and immutable FileRecords to canonical Puffin descriptor and - bitmap verification. It checks exact reference/span/cardinality, sequence and - partition applicability, and maximum position strictly below data record count. - Partition equality normalizes NaNs, preserves signed zero, and handles numeric - precision promotion. Inputs are sorted by referenced canonical key; one previous - key detects duplicate/out-of-order targets even across different Puffin files. - Catalog epoch, table, snapshot, sequence and manifest-list FileId bind the scope. - Count/aggregate-byte/per-blob/per-bitmap limits are independent. Early finish, - corruption, errors and cancellation cannot return success or advance progress. - Eight new tests include contextual manifest decoding, chunk-backed canonical - Puffin reads, multiple blobs, cancellation and boundary failures. -- [ ] **Snapshot admission integration**: the future commit enumerator must - exhaust all candidate manifest readers, produce every live DV/data pair in - referenced-key order under bounded external storage, and supply the trusted - exact total to `SnapshotDvValidator`. Recheck catalog/head fencing before CAS. - Do not derive that total from an untrusted summary or count all position-delete - entries as DVs. Merge/replace prior position deletes and verify actual data-file - row counts through format context. These are R182 composition work, not a - whole-snapshot in-memory collection or a second file-reader state machine. -- [ ] **Finish other independent FileIO work**: metadata projection load/commit - integration, selected-use validation, delegation vending and official client - acceptance remain unfinished. Use the existing execution tasks above. - -### Reuse and integration boundaries - -#### Handover after contextual manifest validation - -- The four approved slices now have a contextual library path: build the trusted - `ManifestContext` from the corresponding table schema/spec, optionally attach - bounded trusted schema history, then use `ManifestReader::open`. Do not use the - legacy `ManifestEntryProjection::new` as full semantic acceptance; it remains - the deliberately partial scalar/collection API for existing callers. -- Reader completion verifies this pipeline and list totals, not whole-snapshot - correctness or content-file truth. Callers must exhaust the reader and handle - final EOF errors. Unknown transform values are retained for reads; write - admission must reject unknown transforms. Variant bounds now decode bounded - primitive-valued objects; actual bound truth still requires data-file context. -- Full delete-file column presence and actual bound correctness require file - context, not only manifest schema. The sorted DV validator is implemented; - snapshot enumeration, prior-delete replacement and admission still belong in - commit processing and remain complex work. -- Multipart response formatting, durable part LastModified and grant/service - limit intersection are implemented as bounded server/library components. - Metadata projection storage/fallback is also implemented; table-load wiring - remains pending with table heads. None requires replacing the metric decoder. - -#### Handover after metadata projection fallback - -- `src/metadata_projection/{model,repository}.rs` implements the optional derived - store, independently of canonical publication. Use `put` only on bounded, - already sealed canonical input; false must never reject publication. No public - HTTP route or table load has been wired, and R180 remains unfinished. -- `MetadataRead::Selected` contains exact raw JSON values for requested top-level - fields (including object/array children). `MetadataRead::Canonical` contains a - boxed streaming reader of the whole original JSON; callers must choose their - bounded parse/stream behavior, not reinterpret it as selected-field bytes. -- No eviction or physical deletion was added. Generation-local derived pages may - leak until R183 just like other unreachable staged data. Keys never cross the - catalog/table/generation/digest/version boundary, and no new lock or unsafe - exception is needed. Admission/fencing still belongs to the calling catalog - operation; this optional store is not an alternate authority. - -#### Handover after multipart responses and limit intersection - -- `MultipartRepository::reserve_part` stamps `modified_ms` from its accepted - `now_ms` before persisting the pending mutation. The FlatBuffers field is - append-only; committed parts with zero/invalid time fail closed. A replacement - gets its own LastModified, and recovery preserves the original pending value. -- `MultipartResponses` formats Create, UploadPart, ListParts, Complete, Abort and - typed S3 errors. UploadPart and ListParts share quoted SHA-256 ETags; Complete - requires the exact Published session and selected FileRecord and receives a - trusted public HTTP object URL from its caller. XML escaping and stable marker - semantics are covered by focused server tests. Request XML parsing and public - dispatch are now connected as described in the checkpoint below. -- `FileTransferAdmission::authorize` consumes a verified grant and parsed native - request, checks table/operation, principal/upload/session credit/expiry, and - intersects service/session byte ceilings. `check_create` is a preflight against - the durable global policy; it does not reserve credits. The caller must invoke - `MultipartAdmission::reserve` before exposing an upload ID. `receive` and - `read_body` call the existing bounded adapters with the intersected ceilings. - Before dispatch, validate Ready catalog context and authenticate SigV4 using - `authenticate_file_request`; afterward, reload the current session/policy and - use only these checked transfer paths. The native listener now applies them. - -#### Checkpoint after SDK-shaped FileIO routes and sealing - -- Native path-style S3 requests now enter the Iceberg listener separately from - general S3 and bearer catalog routes. Signed PUT, HEAD, GET, Range, create, - upload-part, list-parts, Complete and abort use the existing grant, durable - multipart, immutable publication and recovery components. Unsupported bucket - and object operations remain unavailable. Complete XML parsing is bounded, - checks the S3 namespace and ascending part numbers, resolves current durable - revisions and enforces the 5-MiB nonfinal part rule. -- PUT and Complete seal complete canonical bytes before publication. Container - magic and full format validation choose JSON metadata or an unbound Avro, - Parquet, ORC or Puffin record; neither filenames nor upload headers classify - data versus delete use. `FileKind::Unbound` is a storage authority, not a - declared Iceberg use. Selected metadata/manifest use must be checked in - R181/R182 before table head publication. -- Native chunk small writes accept at most the protocol frame payload, 65,502 - bytes. Upload and multipart assembly/recovery use the same block size. The - HTTP adapter slices arbitrary received frames into bounded writer calls; the - listener's Hyper buffer setting is not a hard body-frame ceiling. -- A real-stack manual SigV4 test passed ordinary PUT/HEAD/GET/Range and a - 5-MiB-plus multipart upload, durable ListParts, Complete replay and GET. It - took 136 seconds, so the current 300-second Complete/connection deadline is - not yet sufficient evidence for large-file official-client acceptance. - The pinned S3FileIO baseline and streaming checksum support now pass as detailed - below. Table-side delegated credential vending and the wider client/engine - matrix remain pending. Do not advertise full FileIO. - -#### Checkpoint after official Java FileIO compatibility - -- `FileCompleteBody` sends the XML declaration first, then 10-second whitespace - heartbeats, then exactly one success or error document. A 300-second work - deadline yields a terminal `SlowDown` document; disconnect drops foreground - work, leaving durable recovery in charge. Connections expire after 300 seconds - without successful I/O, not after a fixed total lifetime. Shutdown draining - remains bounded to 300 seconds. These are resource limits, not evidence of - acceptance for arbitrarily large objects. -- `SigV4Verifier::verify_streaming` explicitly opts native uploads into AWS - streaming seed verification. The ordinary verifier still rejects streaming. - `FileUploadBody` verifies every signed chunk, the zero-length terminal chunk, - declared trailing checksum and trailer signature. Unsigned trailer uploads - and signed uploads without trailers also have focused tests. CRC32, CRC32C, - CRC64NVME, SHA-1 and SHA-256 are supported; unknown checksum algorithms fail - closed. Encoded bytes and decoded lengths are bounded separately; parser lines - are capped at 1 KiB and output frames at 64 KiB. Only successful EOF can return - a publishable upload tree. Trailers carried as arbitrary HTTP trailer frames - remain rejected; AWS trailers are decoded from the aws-chunked payload. -- AWS's published signed CRC32C trailer example verifies independently of our - test signer. Negative cases cover changed seeds/chunks/checksums/signatures, - extra bytes, truncation, duplicate framing headers, frame splits and encoded - byte limits. Complete XML accepts predefined and numeric references in ETags - under the same 66-byte decoded bound and still rejects external entities. -- Reproduce the official client test with - `pixi run -e iceberg-e2e test-java-iceberg-fileio-e2e`. The environment pins - Java 21 and Maven 3.9 through `pixi.lock`; the fixture pins Iceberg 1.11.0 and - its AWS bundle. Credentials enter the test process through stdin, not command - arguments. Successful execution took 177.74 seconds including stack startup - and Maven cleanup. Maven reports the official SDK's remaining daemon threads - during in-process cleanup; the Maven process exits successfully. -- Remaining scope: catalog credential vending, selected-use validation, table - heads/load/lifecycle, candidate snapshot admission and commits. Multipart - additional-checksum persistence/Complete fields and the wider release-client - matrix are not covered by this baseline. The existing immutable digest remains - SHA-256; checksum verification does not redefine ETags or file authority. -- Verification passed: affected S3/server `--all-targets` tests with the Iceberg - feature, the pinned Java real-stack test, manual SigV4 PUT/Range/multipart and - Complete replay (137.15 seconds), workspace fmt and `pixi run rs-lint`, and - explicit Iceberg-E2E-feature clippy. The no-default-feature encoding tests also - pass. No new unsafe scope, lock or physical deletion path was introduced. -- Primary references: - [AWS Complete](https://docs.aws.amazon.com/AmazonS3/latest/API/API_CompleteMultipartUpload.html), - [AWS signed chunks](https://docs.aws.amazon.com/AmazonS3/latest/developerguide/sigv4-streaming.html), - [AWS signed trailers](https://docs.aws.amazon.com/AmazonS3/latest/developerguide/sigv4-streaming-trailers.html), - [Iceberg S3OutputStream](https://github.com/apache/iceberg/blob/apache-iceberg-1.11.0/aws/src/main/java/org/apache/iceberg/aws/s3/S3OutputStream.java). - -#### Handover after partition summaries, Variant bounds and DV binding - -- Summaries are decoded by `AvroRecordArray` and `ManifestListProjection` and - validated against historical spec order/types by `ManifestReader`. Exhaust to - EOF before treating totals or null/NaN flags as verified. Unknown transforms - retain bounded values but do not supply filtering semantics. -- Contextual entry projections now validate Variant bound objects automatically. - They retain canonical bytes in metrics and do not expose a general-purpose - Variant document materializer. Bound accuracy against actual data remains a - separate format-level check. -- Use `SnapshotFile { entry, record, context }` only for fully validated live - entries and canonical records loaded from the selected snapshot. Construct one - `SnapshotDvValidator` per frozen `SnapshotDvScope`, pass matching scope on each - `check`, and require `finish`. Sort by native relative-key UTF-8 byte order. - The validator keeps one key, counters, one bounded footer and bitmap window; - its success covers supplied pairs, not enumeration completeness or publication. - Caller-provided row counts currently come from manifests, not Parquet/ORC - footer decoding. No public seal/commit endpoint is enabled by these helpers. -- Changed modules: `src/file/avro/schema/{record_array,projection}.rs`, - `src/manifest/{list,summary,reader,deletion_vectors}.rs`, - `src/manifest/deletion_vectors/binding.rs`, and - `src/manifest/entry/variant.rs` with `variant/{path,primitive}.rs`. - Focused tests: `manifest_summary_test`, `manifest_reader_test`, - `manifest_variant_test`, `manifest_dv_test`, `manifest_dv_partition_test`, - `deletion_vector_test` and `puffin_metadata_test`. -- Complete XML parsing, HTTP composition and physical seal orchestration are - now connected. Next complex slices are selected-use validation, candidate - snapshot enumeration/admission, selected table heads and atomic commits. - Credential vending and official-client acceptance remain separate; R179's - latency decision remains recorded in R177. - -- `src/file/avro/schema/projection.rs` and `projection/compile.rs`: root or nested - scalar cursor; required means schema presence, not a non-null runtime value. - Missing optional paths and null parent records produce `AvroScalar::Null`. - Consumers enforce typed required values; skipped fields still undergo binary - validation. Malformed/duplicate IDs in traversed records fail closed. Primitive - strings borrow the current bounded block. This is not general schema evolution - or complete global Iceberg field-ID validation. -- `src/manifest/list.rs`: typed manifest-list cursor, canonical same-table paths, - length/spec-ID checks, v1 zero sequences, v2/v3 required counts, v3 optional row - IDs, bounded summaries and delete separation. Trusted context and the bound - reader validate summary types and actual partitions. Referenced file existence - and snapshot-wide lineage remain separate. The list writer version is - explicit; do not infer it from the current table version. -- `src/file/multipart_credits.rs`: durable global session/reserved-byte admission - with a single pending CAS journal; `settle` repairs uncertain reservation or - terminal release. `MultipartRecovery` helps that journal before scanning four - sessions. Call admission before exposing an upload; low-level repository test - fixtures can still be uncredited. Release only retained terminal receipts. - These are logical active credits, not cumulative orphan/disk capacity accounting. -- `src/file/multipart_repository/` and recovery/list modules already implement - journaled part replacement, frozen selection, resumable assembly, frozen seal - publication/replay, bounded listing and native background recovery. Do not - implement a second state machine in HTTP handlers. New response formatters and - intersected admission helpers, public routes and physical sealing are connected. - Selected-use validation and standard-client compatibility still need work; - an invalid frozen selection currently requires abort. -- Server `src/iceberg/file_upload.rs`, `file_body.rs`, `file_auth.rs`, - `file_request.rs`, `file_response.rs` and `file_admission.rs` provide bounded - transport, SigV4 grant authentication, operation parsing, response formatting - and limit checks. They are composed in the native FileIO listener. Upload - rejects arbitrary HTTP trailer frames; `FileUploadBody` validates AWS checksum - trailers inside the signed/unsigned aws-chunked payload before publication. -- Formats: JSON validation is structural; Parquet/ORC probes verify framing and - fixed-size hints, not complete footer semantics. Puffin metadata is bounded - plain JSON or one sized LZ4 frame. Avro only has null/raw-deflate codecs. - Canonical bytes remain authority; missing/corrupt projections must fall back. -- Preserve the R179 500-ms acceptance blocker; do not increase timeouts or add - caller retries to claim it passes. R177 also records standard PUT kind binding, - release engine profiles and no-GC deployment capacity policy. No new human - decision was needed for the Avro projection tasks. - -### Resume verification - -- Latest library gate: `pixi run -- cargo test -p crowdb-access-iceberg --all-targets` - passes 290 tests (including partition-summary, Variant and DV-boundary tests).

The tasks 1–3 summary above supersedes statements that -table writes, credential vending or atomic publication are still disconnected. -Remaining program work includes table rename/drop/replace, full selected-use -profiles (including partition statistics), persisted capability activation, -release client/engine matrices, and the explicitly deferred ORC/GC requirements. - -- **Highest: atomic commits and creation (R182)**. Requirement/update evaluation, - immutable candidate metadata, namespace admission, one head-CAS publisher, - lost-response replay and v1/v2/v3 evolution must agree on a single generation. - This depends on unfinished FileIO and table state, so do not implement it as an - isolated HTTP handler or advertise write support from partial coverage. -- **Highest: reclamation safety (R183)**. Cross-snapshot reachability, catalog/table - generations, pins, reader/delegation leases, retained multipart evidence and - crash-safe deletion proofs are coupled. Keep the approved deferral and physical - deletion disabled; this is not a cleanup job that can safely use only TTL. -- **High: remaining FileIO semantics (R180)**. Collection schemas, equality IDs, - partition/metric validation and snapshot-wide DV/row-lineage checks require - bounded traversal plus table context. The scalar bridge and equality-ID lists are landed: - typed IDs/paths, v1/v2/v3 inheritance, atomic failure behavior and cross-block - state have focused tests. Six metric maps now have bounded decoding and structural/count - validation before inheritance. Historical schema/spec context, partition tuples, - typed scalar/geospatial bounds and a list-bound streaming reader are now implemented. - Partition summary decoding and reader containment/EOF validation are implemented. - Variant bound objects also have bounded decoding and typed ordering checks. - The DV validator binds Puffin bytes to live manifest/data records, checks row - range, partition/sequence applicability and uniqueness over sorted inputs. - Remaining complex work includes complete candidate snapshot enumeration, - prior-delete replacement and actual data-file semantics. Use these components; - do not conflate them with full seal or commit acceptance. -- **High: multipart/HTTP composition (R180)**. Durable credits, parts, completion, - publication and recovery primitives are wired into native HTTP routes. A pinned - Java FileIO test covers default signed checksum trailers, Complete, reads and - embedded errors. Wider client profiles, optional multipart checksum metadata, - table credential vending and selected-use semantics remain. - Invalid frozen selections and uncertain publication must not acquire a second - HTTP-only state machine. Standard PUT retains ambiguous kinds as unbound until - selected metadata supplies the declared use, as already approved. -- **High: namespace/table races (R179/R181)**. Create/rename-in versus namespace - drop needs shared admission and crash recovery; bounded table heads, logical - drop and purge intent are still prerequisites. Preserve the separate namespace - latency blocker instead of weakening its acceptance fixture. -- **Medium, good bounded follow-ups**: additional negative format fixtures, - multipart request-body decoding and selected metadata projection consumers. - Take one small verified slice per commit. None alone completes a catalog server. -- **Broad integration cost (R184)**: official FileIO/REST clients, cancellation, - native restarts and engine/version matrices. Start foreground vertical slices - as lifecycle/commit features land; GC-dependent acceptance remains last. Release - engine profiles and no-GC capacity policy remain human choices in R177. - -## Review checkpoint - -- R178 supplies catalog management, authentication, recovery, and config. The - current HTTP dispatcher accepts authenticated config and namespace CRUD. -- R179 has identifiers, properties, authority/mapping records, bounded scans, - conditional deletion, separate writer credentials, payload pages, and durable - create/property/drop drivers, shared helping, periodic repair, listing and REST. - Official CRUD acceptance awaits the R177 latency decision; future table - create/rename-in admission remains pending. -- R180 through R184 have no corresponding completed feature implementations. - Shared infrastructure is reusable, but is not acceptance of these requirements. -- A listening config service already works. A namespace catalog needs R179. - A native catalog that clients can create tables in, write to, and read from - needs R180, R181, R182, and the relevant R184 integration and client tests. -- R177's full correctness milestone includes R183 and all R184 acceptance. - An earlier functional checkpoint must not be labelled that full milestone. - -## Approved reclamation deferral - -- Defer R183 execution, not its backlog or safety contract. R180 explicitly - allows unreachable staged/orphan data to leak before reclamation; R181 permits - logical drop without cleanup; R182 keeps losing candidates unreachable. -- Keep physical deletion of Iceberg-owned files and chunks disabled, including - implicit cleanup by upload expiry, multipart abort, table drop, and catalog - clear. Logical expiration, bounded recovery, and publication fencing still run. -- Preserve ownership, generations, durable operation outcomes, upload state, and - purge intent needed for later candidate discovery. Do not remove the last - evidence of retained storage while recycling bounded foreground state. -- For `purgeRequested=true`, persist a pending proof task before reporting the - logical drop complete, as R181 requires. Do not report physical purge complete - or expose a public file DELETE route. Worker status/control remains unavailable - until implemented and verified. -- Without reclamation, cumulative retained storage is not bounded by per-request - or session limits. Use a capacity-limited trial with monitored free capacity; - stop admitting writes before exhaustion. This is not a sustainable long-running - production storage policy. -- Retention, reader/credential leases, and operator pins must be enforced before - any future deleter is enabled. Deferral is not permission to replace positive - reachability proof with TTL-only deletion. -- Run R184's foreground integration early, but leave its reclamation-dependent - acceptance and original completion status pending. Update upstream milestone - wording reflects the approved split while retaining the full milestone. - -## Dependency-ordered execution - -### Remaining tasks from the current five-task batch - -The first task, the pinned official FileIO baseline, is verified. Details and -commands are in `plan-iceberg-fileio.md`, official Java checkpoint. - -- [ ] **Credential vending**: implement the standard REST storage-credential - response and refresh contract from the pinned OpenAPI and official SDK. Reuse - `FileGrantIssuer`; derive operations from the authenticated read/write role. - Its live endpoint depends on the selected table identity/lifecycle below; - implement the wire/issuer slice first, then attach it with table loads. - Wire slice: `wire/credentials.rs` serializes one exact table prefix and the - SDK's access key, secret, session token and decimal millisecond expiry. Keep - secrets out of Debug. Issuance binds authenticated principal, fresh nonce and - server byte/TTL limits; only the independent writer receives mutations. - Test all four roles, refresh rotation, expiry/overflow and cross-table denial. - Standard evidence: pinned OpenAPI `StorageCredential`/`LoadCredentialsResponse` - and Apache Iceberg 1.11.0 `VendedCredentialsProvider` (requires the expiry - property, refreshes five minutes before expiry, accepts exactly one S3 grant). - SDK factory activation uses `client.refresh-credentials-endpoint`, not the - provider-internal `credentials.uri`; verified against pinned - [AwsClientProperties](https://github.com/apache/iceberg/blob/apache-iceberg-1.11.0/aws/src/main/java/org/apache/iceberg/aws/AwsClientProperties.java) - and [VendedCredentialsProvider](https://github.com/apache/iceberg/blob/apache-iceberg-1.11.0/aws/src/main/java/org/apache/iceberg/aws/s3/VendedCredentialsProvider.java). - Wire/issuer slice verified: library all-target tests, fmt, workspace lint and - explicit server `iceberg-e2e` lint pass. Official Java FileIO fetched the Rust - response from a test HTTP endpoint, cached it, and completed real native PUT, - multipart, HEAD, GET, seek and embedded-error checks (178.19 s). This is not - a production catalog credentials endpoint or a timed refresh acceptance test. - Maven reports the existing SDK daemon-thread cleanup warnings with exit 0. -- [ ] **Selected-use validation**: complete format semantics and validate - canonical unbound files against trusted metadata/manifest declarations. Do not - infer use from names, headers or upload container bytes. - First slice: `ManifestReader` binds unbound canonical uploads only to the - selected manifest declaration; `ManifestListReader` streams the selected list - with one bounded decoded block, exact location/kind checks and cancellation - poisoning. Both require EOF before claiming completion. `bind_kind` must - validate the original authority before constructing any derived view. - Keep historical writer-version selection, snapshot enumeration completeness, - cross-manifest invariants and Parquet/ORC data/delete semantic checks separate; - this streaming slice does not establish a publishable table generation. - Verified the streaming slice with library all-target tests and focused - canonical-corruption/invalid-authority tests, fmt and workspace lint. No table - capability is advertised by these helpers; production credential endpoints - remain dependent on live table authority, not arbitrary caller TableIds. - Verified selection slice: `ManifestListSelection` and `open_selected` bind the - list to trusted historical snapshot ID, parent, sequence and v3 row-ID range. - Validate optional OCF linkage against that selection, reject future manifest - sequences and require newly added manifests to use the snapshot sequence. - Preserve compatibility with writers that omit these non-required OCF keys; - never substitute current table format version for the historical writer. - Standard evidence: pinned specification, Snapshots and Manifest Lists, and - [official ManifestListWriter](https://github.com/apache/iceberg/blob/apache-iceberg-1.11.0/core/src/main/java/org/apache/iceberg/ManifestListWriter.java) - (including literal `null` parent metadata). The official - [ManifestLists reader](https://github.com/apache/iceberg/blob/apache-iceberg-1.11.0/core/src/main/java/org/apache/iceberg/ManifestLists.java) - projects fields rather than requiring the writer's optional OCF linkage. - This slice does not prove row-ID assignment intervals or validate data/delete - bytes. Tests cover optional/official-style - headers, empty-list mismatches, scope overflow, reused/new manifest sequences, - and poisoned cursors after selection failure. - Enumeration slice: `SnapshotManifestReader` owns a fresh selected list and - sequentially resolves each canonical manifest plus trusted historical context. - It cannot skip missing/corrupt manifests or bypass EOF totals. Retain one list - block, one manifest reader and a separately budgeted identity index; cap manifests, entries and aggregate - manifest bytes. `finish` exposes counts only after the list and every manifest - reached verified EOF. Cancellation during authority resolution or inner reads - poisons the outer cursor. `SnapshotManifestSource` implementations must fence - the candidate generation; none is wired to production table authority yet. - Enumeration completion is not data/delete byte validation, DV bitmap/data-row - binding, historical row-ID preservation, or publication proof. - Verification: 12 added selection/enumeration tests pass; library all-target - tests, workspace fmt check and workspace clippy pass. Fixture chunk copies - preserve owner binding by writing fresh trees rather than relabeling FileIds. - Historical-read correction: snapshot JSON does not carry a writer format - version. Follow the specification's Writer Requirements read-compatibility - matrix instead of inferring an exact historical version. `ManifestListSelection` - now carries current `table_version`; `ManifestListProjection::for_read` defaults - missing content/sequences and retains unknown optional counts. The strict `new` - projection remains available for validating a known writer's output; commit - integration must enforce new-file writer requirements separately. - Upgraded v3 tables accept old snapshots with no row lineage, while malformed - present values and inconsistent optional OCF linkage still fail. Canonical - list tests cover v1/v2 snapshots in v2/v3 tables with and without writer headers. - Evidence: pinned specification Writer Requirements and Row Lineage upgrade - rules; official - [SnapshotParser](https://github.com/apache/iceberg/blob/apache-iceberg-1.11.0/core/src/main/java/org/apache/iceberg/SnapshotParser.java) - preserves historical absent sequence/lineage, and - [GenericManifestFile](https://github.com/apache/iceberg/blob/apache-iceberg-1.11.0/core/src/main/java/org/apache/iceberg/GenericManifestFile.java) - applies field-based defaults without guessing a historical writer version. - - Historical-read gates: 24 focused list/snapshot tests, workspace fmt and - workspace clippy pass. No new format capability or production route is enabled. - - Remaining execution slices from the ten-task batch, in dependency order: - 2. Cross-manifest identity/descriptor consistency and row-ID assignment ranges. - Row-ID slice implemented: keep only the snapshot allocation and current/next - manifest cursor; use actual inherited counts, not row-count estimates. - Reject missing assignments, overlapping newly assigned intervals, new ranges - escaping `first-row-id + added-rows`, and reused ranges crossing into the new - allocation. Gaps and unused allocation remain valid. Scope checks do not - replace comparison against prior metadata to prove preservation of old IDs. - Exact identity slice: `SnapshotIdentityIndex` rejects repeated manifests and - live ordinary paths, checks shared Puffin physical lengths, disjoint DV spans - and unique DV targets. Deleted entries do not count as live references. - Distinct DVs in the same Puffin file are valid (specification Row-level Deletes). - Integrate checks before entries escape `SnapshotManifestReader`; EOF summary - is unavailable after index failure. Independent node and retained-key-byte - limits bound transient memory (hard ceilings: one million keys and 64 MiB of - key bytes); no eviction, probabilistic membership or unbounded collection. - Larger snapshots currently fail the configured budget rather than spilling; - future external-memory optimization must retain exactness and orphan evidence. - These limits are not service-wide admission until production wiring lands. - Verified 17 identity/snapshot tests plus workspace fmt/clippy; the earlier - row-ID slice passed 11 snapshot tests. Remaining historical-preservation and - physical-file checks require prior selected metadata and canonical readers. - 3. Canonical Parquet schema/field-ID/row-count and selected data/delete checks. - Footer slice: `file/parquet/` decodes bounded Thrift Compact metadata from - canonical footer ranges, never stored hints. Independent footer/value/depth/ - schema/row-group limits bound input and decoded structures. Validate required - field types, duplicate Thrift fields, schema preorder/IDs, row-group column - counts and physical types, column byte spans, and aggregate rows/byte counts. - Reject encrypted/external metadata explicitly. This is not page decoding or - complete Iceberg logical-type/equality/position-delete validation. Typed - logical annotations now retain decimal parameters, integer width/signedness, - time units/UTC flags, Variant version and spatial CRS/algorithm. Validate - required annotation wire types and unions; unknown annotation IDs remain - explicit. Physical/logical compatibility and legacy annotation agreement - still require separate validation. - Evidence: Apache - [Parquet 2.10 IDL](https://github.com/apache/parquet-format/blob/apache-parquet-format-2.10.0/src/main/thrift/parquet.thrift) - and [Compact protocol](https://github.com/apache/thrift/blob/master/doc/specs/thrift-compact-protocol.md). - `parquet_official_footer.rs` embeds the 730-byte footer from Apache - [alltypes_plain.parquet](https://github.com/apache/parquet-testing/blob/master/data/alltypes_plain.parquet) - (original file length 1851, footer offset 1113), exercising real delta headers. - The test supplies placeholder body bytes and tests only footer interpretation, - not those data pages or official Iceberg writer acceptance. - Footer checkpoint: library all-target tests, seven focused footer tests, - workspace fmt and clippy pass. Collections grow only as decoded values arrive; - nested advertised sizes cannot multiply speculative vector reservations. - Annotation checkpoint: three annotation tests and seven footer tests plus - workspace fmt/clippy pass. Current Parquet IDL supplies Variant/spatial - annotations; Iceberg's pinned mapping and Java `TypeToMessageType` remain - the selected-use compatibility contract, not generic Parquet permissiveness. - Column checkpoint: match every ordered column path to its schema leaf, - excluding the root and retaining nested/repeated ancestry. Non-repeated - column value counts (including nulls) must equal row-group row counts; - repeated columns are not incorrectly constrained to that equality. Four - column tests cover swapped same-type siblings, paths, counts and ancestry; - all 14 focused Parquet tests and workspace fmt/clippy pass. - Selected footer binding: `manifest::read_selected_parquet_metadata` checks - table/location/format/length and live entry status before storage access, - binds content kind from the manifest without changing the upload, and compares - canonical footer rows with manifest `record_count`. Its result is metadata, - not a schema/delete/page-validation proof. Three tests cover all content kinds, - incompatible prebound kinds, no-I/O descriptor rejection and false row counts. - Selected schema/delete slice now implemented through `read_parquet_selection`, - `validate_parquet_schema` and `validate_parquet_position_deletes`: - - Field IDs bind to retained historical fields and logical parents; explicit - bounded name mappings normalize collection paths. No-ID files use the SDK's - top-level ordinal fallback. Missing required fields accept non-null initial - defaults; default value interpretation remains the table/read planner's job. - - Validate primitive/logical mappings, numeric and decimal promotions, - v3 date promotion, nested/legacy LIST, MAP key/value identity, and Variant - unshredded/shredded schema layouts. Variant payloads are not decoded here. - - Equality-delete IDs must be present, unique, eligible primitive fields - outside collections. Position-delete reserved columns and optional row - projection bind separately; optional row payloads are not decoded here. - - Canonical position-delete pages validate every path/position pair, sorted - order, referenced-file binding and applicable target row bounds. Duplicate - pairs are permitted. The caller resolves selected-scope applicability; - old delete files may reference removed data files. Results publish only - after exact EOF; these functions change no catalog authority. - - Page V1/V2, PLAIN, dictionary RLE/bitpacking, delta integer/string and - byte-stream-split encodings are bounded independently by page bytes, - decoded values, page count and total rows. Supported codecs: uncompressed, - Snappy, Gzip, Zstd and LZ4_RAW. Unsupported codecs/encodings fail explicitly; - this is not an unrestricted Parquet reader. Maximum decoded page 8 MiB; - Zstd windows also capped at 8 MiB. CRC is checked when present. - - `parquet_iceberg_fixture.rs` contains complete files produced by Iceberg - Java 1.11.0 / parquet-mr 1.17.1, Zstd, both page versions, 100 deletes each. - Tests read their actual body bytes, including corruption rejection. - Reproduction source and pinned Maven dependencies are in - `tests/common/parquet_java/`; run Maven through `pixi run -e iceberg-e2e` - with `JAVA_HOME="$CONDA_PREFIX/lib/jvm"`, goal `compile exec:java` and - `-Dexec.args="s3://iceberg-aeaqcaibaeaqcaibaeaqcaibae/t/02020202020202020202020202020202/data/target.parquet"`. - The normal Rust gate uses embedded fixtures and does not require Maven. - - Added safe Snappy/Zstd dependencies; lockfile pins jobserver 0.1.32 instead - of 0.1.35 to preserve the workspace's Rust 1.75 compatibility floor. - No new local unsafe exception or production lock is introduced. - Schema/delete checkpoint: 22 new tests pass, including complete official SDK - page fixtures and corrupt-body rejection. Library `--all-targets`, workspace - `rs-fmt-check` and `rs-lint` pass. Compatibility decisions follow Iceberg - 1.11.0 `ParquetSchemaUtil`, `TypeToMessageType`, `ApplyNameMapping` and - `BaseParquetReaders`, plus Parquet encoding and Variant shredding contracts. - Combined checkpoint: `pixi run -- cargo test -p crowdb-access-iceberg - --all-targets`, `pixi run rs-fmt-check` and `pixi run rs-lint` pass. These are - library gates; no production table API or new server acceptance is claimed. - Remaining integration/coverage within this task: - - Supply trusted historical contexts, default values and name mappings from - selected table metadata. Unknown-to-concrete promotion remains explicitly - unsupported; full default-value validation belongs to metadata validation. - Expand official SDK fixtures for nested data, Variant and spatial fields; - current schema cases use synthetic structures, not official body readers. - - Equality values and optional position-delete row payloads are not scanned; - general data-page validation is outside this reserved-column decoder. - - Connect the resulting validation to full selected snapshot traversal; - a standalone metadata-returning function must not become a commit proof. - 4. Deferred to R186: canonical ORC equivalent checks with bounded decoding. - Consult the current - [ORC protobuf](https://github.com/apache/orc-format/blob/main/src/main/proto/orc/proto/orc_proto.proto) - alongside pinned Iceberg ORC mapping and official writer/reader code. The - specification website's Footer field 11 differs from the current protobuf - (`calendar`); do not copy that example as the wire authority. Bound encoded - bytes, decoded bytes, protobuf work, type depth/count and stripe count - independently. Compression framing uses independent three-byte chunks; - codec/column encryption support must be explicit, not silently ignored. - 5. Bind complete snapshot enumeration, actual file row counts and DV validation. - Current user-approved sequence skips deferred ORC: finish this integration, - then items 6, 7 and 8. Reject unsupported selected formats explicitly. - Library orchestration implemented as `manifest::validate_snapshot_files`: - three complete bounded enumerations validate data first, DVs second and - remaining deletes last. Canonical Parquet footer rows/schema populate an - independently count/byte-bounded index; retained historical contexts are - shared per manifest and charged to that index. No metrics maps are retained. - Position deletes apply only to selected data with matching spec/partition - and a data sequence no greater than the delete sequence, unless superseded - by an applicable DV. Removed or otherwise inapplicable targets do not borrow - another file's row count. Every DV still validates its canonical descriptor - and bitmap; applicable DVs additionally check the canonical data row bound. - Independent aggregate delete-row, DV-count/blob-byte and index budgets fail - closed; errors/cancellation return no completion result or authority mutation. - Six integration tests cover actual SDK position-delete pages, manifest - ordering, stale targets, false footer counts, missing authorities, deferred - ORC, index limits, aggregate equality-delete work, DV supersession and DV row overflow. Canonical data footer - fixtures intentionally do not claim general data-page scanning. - Remaining: generation-trusted source wiring from item 7, prior-snapshot - delete/DV preservation in commit validation, and production table publication. - The summary is not a full commit proof or equality-value scan. - 6. Bounded TableHead/name mappings and generation-qualified repository. - Library core implemented in `src/table/`: separate bounded head and name - mapping records, append-only FlatBuffers union tags, strict key binding, - stable TableId versus optional v1 Iceberg UUID, namespace/name epoch, - lifecycle, metadata generation/location/FileId/digest and operation fences. - `TableRepository::select` resolves only published head-qualified names and - binds one immutable JSON record without rereading a newer head midway. - `ensure_current` compares the complete head and active catalog context; it - is explicitly a read check, never a replacement for publication CAS. - Four tests cover record bounds/key/version checks, stale reservations/names, - tombstones, metadata corruption, catalog retirement and generation changes. - Tests install fixture records only; no alternate production publisher or - new unsafe exception/lock is introduced. Full namespace/REST composition, - JSON validation and ALL/REFS responses remain in items 7 and 8. - Checkpoint gates: both `crowdb-access-iceberg` and `crowdb-protocol` - `--all-targets` tests pass; the final added equality-work case also passes - its focused gate. Workspace `rs-fmt-check` and `rs-lint` pass. No server - endpoint or complete table metadata acceptance is claimed by this checkpoint. - 7. Full v1/v2/v3 table metadata validation, preserving original JSON. - Implemented library checkpoint: `TableMetadataDocument` preserves original - bytes, verifies selected head/digest, and decodes duplicate-free JSON under - independent byte/value/string/depth/collection limits. Canonical reads bind - the immutable file identity and verify the entire file before parsing. - Version envelopes, UUID/native location binding, independent schema - structure/identifier checks and last-column bounds are validated. Snapshot - graphs, retained parent sequencing, refs/main, row allocation ranges, logs, - statistics and encryption-key structures are checked without treating these - structures as proof of their files. Upgraded sequence-zero history and - missing historical row lineage remain readable; log ordering follows the - official SDK's 60-second clock-skew tolerance. - Pinned Java 1.11.0 `TableMetadataParser` v1/v2/v3 empty-table fixtures are - generated by `TestMetadataFixtures` in the existing Maven harness and - checked for byte-preserving reads. Thirteen new tests cover this checkpoint; - SDK fixtures do not yet cover evolved schemas or nonempty snapshots. - Follow-up implemented: typed initial/write defaults (including recursive - collection values, typed map-key uniqueness, decimal scale/precision, - temporal precision/range and empty struct defaults); bounded embedded name - mapping; partition field identities/source/transform checks and sort order - direction/null-order checks. Default layouts bind current schema; historical - layouts retain dropped sources instead of binding every old spec to current - columns. Independent schemas remain readable without inventing a linear - evolution history from their array order. Legacy v1 schema IDs are retained. - Java fixtures now include v2/v3 dropped partition/sort source columns and v3 - decimal/nanosecond defaults, produced and round-tripped by the pinned SDK. - Remaining: prior/candidate schema and partition/sort evolution validation, - including immutable initial defaults, ID reuse and upgrades; trusted - manifest contexts and complete file-validation wiring. These checks need - selected prior-generation authority; do not mistake document parsing for - commit admission. Expand nonempty official snapshot fixtures before closure. - Implemented checkpoint: `commit::validate_metadata_transition` binds prior/candidate - identities, the immediate successor generation, an explicit ordered upgrade - trace, monotone allocation counters and retained/new snapshot distinctions. - Never infer update order from schema-array ordering: the official builder - supports selecting an older retained schema before further updates. The - ordered evaluator must validate each actual schema/layout update at its - application point; this transition helper is deliberately not a full commit - proof. Preserve allocations from intermediate snapshots removed in the same - transaction and require lineage on newly added v3 snapshots only. - The closed `TableRequirement` union covers all eight pinned table requirement - variants, including required-but-nullable ref snapshot IDs, implicit v1 main, - legacy partition high-water inference and distinct invalid/budget/conflict - results. Evaluation is pure over one selected document; wire request bounds, - ordered updates and CAS/recovery are still separate unfinished phases. - Eight transition/requirement tests plus metadata/load/list regression tests - pass, with workspace fmt/clippy gates. Do not advertise commit support yet. - Next wire checkpoint: `CommitRequest::decode` bounds complete JSON and both - union counts before returning typed requirements and all 23 table update - variants. Unknown/view actions, duplicate keys at any depth, malformed - payload shapes and route/body identifier mismatch fail closed. Nested schema, - layout, snapshot and auxiliary payloads retain original raw JSON separately - from their decoded fields so future optional numbers are not rounded during - candidate construction. Four request tests cover this layer; decoding is - not update evaluation or semantic admission. The direct v1-to-v3 policy was - subsequently confirmed in R177: the ordered evaluator expands it into both - adjacent internal transitions, rather than rejecting the client request. - Scalar admission now rejects malformed UUIDs, unsupported target versions, - invalid schema/spec/order selectors and invalid branch/tag retention values. - The `-1` last-added selector remains legal; actual existence, source-version - transitions and native location authority belong to ordered evaluation. - Reference retention follows the pinned Java `SnapshotRef.Builder`: positive - values only, with branch-only minimum-count and snapshot-age settings. - Six request tests pass, including null retention, integer boundaries and - duplicate removal IDs. Deprecated last-column/statistics snapshot fields - must not become authority: the pinned `MetadataUpdateParser` derives these - from nested payloads instead. Nested payload semantics remain unfinished. - Retained-definition checkpoint: transitions now reject mutation of an - existing schema/spec/order ID, including changed field names, transforms, - sort direction and defaults. Definition comparison charges every nested JSON - value before cloning, under the shared transition work limit. Legacy v1 - schema/spec envelopes and implicit partition IDs normalize to modern forms; - empty identifier-ID sets and their ordering do not invent a change. - Removed history and new definition IDs remain legal at this layer. New-ID - schema evolution still needs ordered validation and is not inferred from the - final current schema. Seven transition tests cover this checkpoint. The - legacy counter fixture now retains spec 0 instead of changing its meaning - during an upgrade. No commit endpoint or publication path is enabled. - Generation-context checkpoint: `TableMetadataDocument::manifest_context` - selects retained schema/spec IDs from that document, binds the actual pair, - and optionally attaches bounded retained schema history for dropped-column - metrics. Lookup and nested reconstruction share an explicit work budget. - Current schema is never substituted for a requested historical schema; - missing history fails closed rather than trusting uploaded Avro headers. - Three tests cover historical partition sources, incompatible pairs, v1 - implicit IDs, missing history and count/work limits. This is the context - factory only: canonical file resolution, reused-manifest provenance after - schema expiration, complete snapshot validation and publication fencing - remain to be composed by the evaluator/source layer. - Nonempty pinned SDK fixtures now cover all three table versions. The Java - generator `TestSnapshotMetadataFixtures` adds two snapshots, moves main, - tags the first snapshot and round-trips the canonical JSON through Iceberg - 1.11.0. Rust verifies original bytes, parents, v1 sequence-zero inheritance, - refs and v3 row allocations against the generated documents. This fixture - validates metadata interoperability, not the referenced Avro files or REST - E2E. Regenerate with the existing Maven harness using - `-Dexec.mainClass=TestSnapshotMetadataFixtures` and the native test table URI. - Verification: the Maven generator succeeds (existing SLF4J provider warnings - are nonfatal); complete library `--all-targets`, workspace fmt and clippy - pass after these transition/context/SDK-fixture checkpoints. - Keep `TableMetadataDocument` explicitly documented as a partial validation - result, not a publishable generation or a REST capability. No endpoint is - advertised by this checkpoint. Files: `src/table/metadata.rs`, its children, - and `tests/table_metadata_*_test.rs` in `crowdb-access-iceberg`. - Checkpoint gates: library `--all-targets` tests pass; final focused metadata - tests (13), workspace `rs-fmt-check` and `rs-lint` pass. No user-guide changes. - Cross-check pinned spec and official SDK fixtures before accepting historical - schema/spec combinations; do not treat manifest header claims as trusted - table metadata or assume all historical schemas remain in current metadata. - 8. Generation-consistent load/list/exists, ALL/REFS, ETags and fallback. - Implemented library read slice: `TableLoader` resolves live namespace and - table identities, reads one selected canonical file, then rechecks head and - namespace identity/name epoch. Concurrent changes fail with conflict rather - than mixing metadata generations. ALL returns original bytes; REFS selects - branch/tag target snapshots and preserves other raw JSON values. ETags bind - catalog/TableId/generation/digest and loading mode, as required by the REST - specification; a matching conditional request cannot bypass corruption or - lifecycle checks. Canonical-only loading works without projections; no - projection fast path is enabled before an equivalent validation proof exists. - `TableLister` qualifies each mapping against its head, signs namespace/name - epoch/context/page-size-bound tokens and counts stale entries toward work. - Absent tokens collect the complete bounded result; empty tokens start paging. - Work and retained-name byte exhaustion fail before any result is returned. - Files: `src/table/load.rs`, `list.rs`, `list/token.rs`; table load/list tests. - Access Server adapter checkpoint: `iceberg/table_read.rs` composes GET load, - HEAD exists and complete/paged table listing after shared bearer/catalog - admission. It preserves raw metadata inside the standard response envelope, - uses mode-specific ETags/304, checks query/header bounds and single path - decoding, and retains one of four lock-free spool permits through response - delivery. Complete and paged lists share admission; output bytes are capped - before any response is sent. Failed requests release admission. - Five fixture-backed TCP tests cover ALL/REFS, conditional/HEAD, large unknown - numeric values, escaped names, token binding, all credential roles, missing - objects, corruption and resource admission. Setup is exclusively through - `with_table_reads_for_tests` behind `test-util`; production runtime and - advertised capabilities remain unchanged. No second publisher is introduced. - Remaining: production activation with credential vending and final metadata - validation; official-client ALL/REFS/conditional and complete/paged list E2E. - Run server tests and clippy with `--features iceberg`: default server feature - selection skips these tests entirely and is not evidence of validation. - Keep table capabilities unadvertised until these integration gates pass. - Adapter gates pass: server `--features iceberg --all-targets` tests and - clippy, production-only `--no-default-features --features iceberg` library - check, workspace fmt and `rs-lint`. The native/full-stack E2E feature is - intentionally separate and is not claimed by this checkpoint. - Official Java RESTCatalog read acceptance now passes against the same TCP - fixture service: page-size-one listing, HEAD existence/missing table, ALL - and REFS loads, repeated conditional loads, tag/main state, escaped names - and REFS-to-ALL snapshot hydration. A test FileIO throws on every file - operation, proving hydration uses REST rather than hidden file access. - Fixture-installed handlers advertise exactly the three implemented read - endpoints so the pinned SDK endpoint checks run normally. Production cannot - install them yet; its config remains unchanged and disabled table routes - return the standard unsupported response. This is official-client protocol - acceptance over fixture authority, not native-backend or commit E2E. - Files: `tests/iceberg_table_sdk_test.rs` and - `tests/common/iceberg_java/src/main/java/TestIcebergCatalogReads.java`. - Run explicitly (the Maven-dependent test is ignored by ordinary suites): - `pixi run -e iceberg-e2e -- bash -c 'export JAVA_HOME="$CONDA_PREFIX/lib/jvm" CROWDB_ICEBERG_E2E_MVN="$CONDA_PREFIX/bin/mvn"; pixi run -e default -- cargo test -p crowdb-access-server --features iceberg-e2e --test iceberg_table_sdk_test -- --ignored --nocapture'`. - The explicit inner `-e default` is required: the Java environment has no - Cargo, and an unqualified nested `pixi run` inherits that environment. - SDK read gates pass: the explicit ignored Java test, server Iceberg-feature - all-target tests/clippy, the SDK-feature target clippy, workspace fmt/lint. - Selected-use name-mapping compilation remains pending. Inspection of the - pinned SDK found dot-flattening and repeated-null-ID indexing limitations - relative to the table specification; the compatibility policy is recorded - in R177 rather than silently adding a restriction or changing field binding. - Gates for this read/default slice: library all-target tests and final focused - metadata/load/list tests pass, as do workspace fmt/clippy; pinned Java fixture - generation succeeds (nonfatal existing SLF4J binding warnings only). - 9. Production credentials with live table authorization and timed SDK refresh. - 10.

Run the - pinned compatibility kit, Java/Rust clients and supported engine profiles; - publish executable version/capability results. Explicitly record pending GC - coverage rather than closing R184. Files: library `src/rest/`, server runtime, - conformance fixtures, test environment and a per-requirement REST plan. -- [ ] **Implement reclamation later**: durable candidates, bounded reachability, - retention/pins, deletion proofs, isolated worker budgets and operator controls. - Reconcile data retained during the functional checkpoint. Close R183 only after - deletion safety and restart gates. Files: library `src/gc/`, server operator - integration and tests; a new reclamation plan. -- [ ] **Close full conformance**: run remaining reclamation-dependent and complete - cross-feature acceptance, then close R184 and the original correctness - milestone. R185 cache optimization remains outside this plan. Files: client - fixtures, affected permanent design, requirement/index and execution plans. - -## Consolidated files and verification - -- Production: `lib/crowdb-access-iceberg/src/`, scoped additions to - `lib/crowdb-protocol/src/fbs/iceberg.fbs`, and - `app/crowdb-access-server/src/iceberg/`. -- Tests: `lib/crowdb-access-iceberg/tests/`, - `app/crowdb-access-server/tests/`, protocol tests when schema changes, and - pinned conformance environments.

Prefix server-spawning tests with `pixi run clean-env &&`. - Passing config-only client tests does not count as full catalog acceptance. -- Keep coherent verified commits and truthful checkpoints. A seven-hour absence - is not a delivery estimate for six requirements; start with remaining R179 - execution/recovery and continue in the approved order, bypassing only tasks that - depend on unresolved human decisions recorded in R177. +- Prefix native tests with clean-env using the same isolated + `CROWDB_RUNTIME_ROOT=$PWD/.crowdb-runtime/ephemeral/iceberg-catalog-e2e`; + preserve unrelated persistent port claims.

This CAS validates admission without changing the name epoch or - property revision. Reserve-before-admit ordering ensures that drop either sees - the reservation or wins the parent CAS and prevents publication. Cross-namespace - table moves use this protocol for their destination too. - Drop CASes `Ready` to `Dropping` before scanning both child index ranges. - Published children cause a return to `Ready` and a not-empty result. Unresolved - reservations block an empty proof; bounded recovery settles them, with a - retryable 503 if the work budget expires.

Keep necessary unsafe code + confined to the existing FFI and low-level boundaries. +- Put integration tests in each crate's `tests/` directory. +- Put shared integration-test helpers in `tests/common/` and name helper types + with a `Test` prefix. +- Use structured `tracing` fields and established domain identifiers. +- Follow the existing `foo.rs` plus `foo/` module layout; do not add `mod.rs`. + +### C++ + +- Follow the repository `.clang-format` and `.clang-tidy` configuration. +- Keep public subsystem headers under the matching `include//` tree and + private headers with their implementation. +- Add GoogleTest coverage under the owning component's `tests/` directory. -### C++ (crowdb-tree) +### Web UI -- Follow `.clang-format` and `.clang-tidy` configs. -- GoogleTest for tests under `lib/crowdb-tree/tests/`. +- Follow existing React and TypeScript component patterns. +- Add focused unit tests and update Playwright E2E coverage for visible behavior. +- Verify the real backend path when UI behavior depends on service state. -### Design Docs +A bug fix should normally add a failing regression test first, then fix the root +cause. Do not weaken assertions, add retries, disable durability, or bypass +security boundaries to make a test pass. -- Start at `doc/doc_index.md` — match your task to a row, then open only that doc. -- If you add/rename/rescope a doc, update `doc_index.md` in the same commit. -- See `doc/design/kv/design-crowdb-kv.md` for architecture context before making non-trivial changes. +## Pull requests -## Pull Request Process +1.

They must build the workspace, discover +an internal process order, provision topology and storage metadata, initialize +credentials and an Iceberg catalog, and keep several processes alive. This +blocks the development, demonstration, CI, and client-interoperability use cases +defined by the source Docker release brief provided for this requirement. + +The existing full-stack harness proves many components together, but its +in-process setup and temporary paths are not a distributable runtime contract. +The [user guide](../user-manual/user-guide.md) describes manual service +operation, while the [ChunkDB root design](../design/chunkdb/design-crowdb-chunkdb.md) +permits an explicit `unsafe_colocated` minimum topology without promising disk, +node, or zone fault tolerance. Packaging ad hoc test behavior would create a +second storage semantic, hide partial startup, expose internal ports, or lose +state on restart. The preview instead needs a bounded, reproducible composition +of the normal binaries with an honest non-production boundary. + +`crowdb-web` also has an unresolved authority split that a container must not +preserve. Its current `--config` path loads one `ConsoleConfig`/`registry.toml` +containing racks, nodes, servers, stores, groups, process launch settings, and +management endpoints. Lifecycle handlers commit that local file first and then +attempt Group 0 sysdata updates best-effort, so a failed Group 0 write can leave +the UI and cluster divergent. Startup logs that Group 0 is authoritative when it +is ready, but `startup_topology_check` still calls the local +`restore_persisted_topology` path. The same file therefore mixes cluster +authority, bootstrap discovery, machine-local launch policy, runtime endpoint +hints, and UI state; two consoles can independently overwrite different local +truths. Group 0 already owns cluster topology and service registration, while +binary paths, SSH/local launch settings, PIDs, and monitor state are deployment +concerns. The Docker composition needs that boundary corrected rather than +backing up another `registry.toml` beside Group 0. + +Concrete scenarios are a developer uploading and range-reading Parquet through +S3, a PyIceberg client using the enabled REST catalog and FileIO operations, an +operator viewing the same instance in the web console, and a CI job restarting +the container against the same volume before repeating those operations. + +## Solution + +The first image is a single-host preview for disposable development and +integration data. It is not a production, high-availability, upgrade-stable, or +fault-tolerant deployment. + +- **DOCKER-I1 — One-command service:** one documented container invocation + starts one usable CROWDB instance and exposes only S3 on port 16000, Iceberg + REST/FileIO on port 8181, and the web console on port 14000. +- **DOCKER-I2 — Product-path fidelity:** the image runs the normal + `crowdb-kv-server`, `crowdb-diskdb`, `crowdb-diskio`, `crowdb-chunkdb`, + `crowdb-chunk-kv-server`, `crowdb-access-server`, `crowdb-iceberg`, and + `crowdb-web` binaries. Docker-only code may compose and bootstrap them but may + not replace their protocol or persistence semantics. +- **DOCKER-I3 — One durable boundary:** all durable database files, topology, + bootstrap state, credentials, and bounded rotating logs live below the single + `/opt/crowdb/data` mounted data root. Executables and packaged UI/config + templates are immutable image content; generated runtime configs, sockets, + status, and process IDs live below `/opt/crowdb/run` and are disposable. +- **DOCKER-I4 — Dependency-gated readiness:** container readiness becomes true + only after durable bootstrap is complete and KV, disk, chunk, S3, Iceberg, and + web probes all confirm the same instance is usable. A live PID is not proof of + readiness. +- **DOCKER-I5 — Monitored recovery:** a dedicated `crowdb-monitor` daemon is PID + 1 and the sole owner of every child process. It detects unexpected exits and + failed bounded liveness probes, drops readiness before recovery, terminates and + reaps the old process, and restarts the failed process plus affected dependents + in dependency order with the same durable identity and configuration. Restart + attempts use bounded backoff and a finite crash-loop budget; exhaustion + terminates the + container nonzero so the container runtime's restart policy can recreate it. + `SIGTERM` disables restart, stops external admission first, drains bounded + work, stops dependent services in reverse order, and leaves restartable + durable state. +- **DOCKER-I6 — Secret boundary:** the image contains no baked-in credentials or + fixed production secrets. Secret values never appear in image layers, command + arguments, health output, or ordinary logs. +- **DOCKER-I7 — Honest preview:** startup output, UI, examples, labels, and + release metadata identify this as a single-node non-production preview and + advertise only capabilities proven by its pinned acceptance matrix. +- **DOCKER-I8 — Runtime-only initialization:** the image contains no initialized + disk, topology, group, tenant, catalog, or bootstrap manifest. On an empty data + root, `crowdb-monitor` creates Group 0, Group 1, and the remaining topology at + runtime. On a complete existing data root it performs validation only and + never reissues creation. An interrupted initialization resumes with the same + durable identities; unknown or conflicting existing state fails without + mutation. +- **DOCKER-I9 — Convenient authenticated access:** on first boot the monitor + generates strong S3 and Iceberg credentials, stores them only in the mounted + secret directory with mode 0600, and exposes client credentials through an + explicit local retrieval command. Startup logs print the retrieval command and + public endpoints but never credential values. +- **DOCKER-I10 — Honest multi-disk simulation:** the preview provisions one node, + one disk group, and four 16 GiB sparse file-backed disks with one zone each. + Each registered disk has its own stable identity and backing file so DiskDB and + DiskIO exercise a normal multi-disk topology. All files remain on one host + filesystem and are not presented as replica or independent failure-domain + durability. +- **DOCKER-I11 — One configuration authority:** Group 0 is the sole durable + authority for cluster topology and service registration. `crowdb-web.toml` + contains only web-process startup policy. `registry.toml`, when used outside + this image, contains only machine-local launch records and cannot override or + restore Group 0 state. Container mode has no `registry.toml` and never falls + back to local topology after Group 0 exists. +- **DOCKER-I12 — Verifiable preview publication:** release-tag workflows publish + the gated `linux/amd64` image to one public Docker Hub repository only after + manual approval. Version and `git-` tags are immutable; `preview` is the + sole moving convenience tag and `latest` is not published. Every public digest + has a verifiable signature, SBOM, and build provenance. Pull-request workflows + build and test but have no publication authority. +- **DOCKER-I13 — Deployment-profile boundary:** container implementation lives + under the repository-root `container/` directory. `crowdb-monitor` provides a + topology-neutral process graph, supervision, probe, rendering, and bootstrap + runtime; the named **CROWDB Single-Node Preview** profile supplies this + requirement's two groups, four file disks, services, ports, and paths. A future + multi-node image or bare-metal launcher can reuse the monitor without adding + single-node policy branches to its supervision core. + +```text +crowdb-monitor (PID 1) -> start / probe / restart every process + host clients -> S3 access server -----------+ + -> Iceberg REST/FileIO --------+-> Chunk-KV -> ChunkDB -> DiskDB/DiskIO + -> web console ----------------+ | + +-> one KV server + +-> Group 0: system + +-> Group 1: data +``` + +The source layout for this deployment is: + +```text +container/ + crowdb-monitor/ reusable deployment runtime crate and binary + single-node-preview/ CROWDB Single-Node Preview profile + Dockerfile amd64 multi-stage image + templates/ profile-owned service configuration inputs + tests/ profile and container acceptance assets +``` + +Only the current profile is created by R187. Later container profiles may add +sibling directories; a later bare-metal requirement may package the same monitor +without moving or duplicating its runtime code. + +### Web configuration authority + +- **Group 0:** owns racks, nodes, disk groups, disks, stores, groups, replicas, + bindings, and the service registry. Web topology reads and mutations use Group + 0 directly; a successful local file write cannot substitute for a failed Group + 0 mutation. When Group 0 is unavailable after initialization, topology APIs + fail unavailable rather than serving or restoring a local topology copy. +- **`crowdb-web.toml`:** is a versioned, non-secret process configuration. It + contains the web bind address and port, Group 0 management seeds, packaged UI + root, monitor status endpoint, log policy, request bounds, and a mode selecting + monitor-managed or standalone operation. It contains no racks, nodes, stores, + groups, replicas, service inventory, PIDs, binary paths, credentials, or SSH + material. In this image `crowdb-monitor` renders it at + `/opt/crowdb/run/config/crowdb-web.toml` on every start and invokes + `crowdb-web --config` with that path. +- **`registry.toml`:** is an optional, versioned standalone deployment registry, + selected only by a separate `crowdb-web --registry` option. It may map stable + Group 0 node/service identities to machine-local connection and launch policy: + host, SSH credential reference, binary and service-config path, workspace, and + auto-start choice. It stores no topology relationships, stores, groups, + replicas, authoritative service endpoint, health, PID, monitor state, UI + preference, or inline secret. Container monitor-managed mode rejects a + registry path because `crowdb-monitor` owns every process. +- **Runtime/UI state:** live endpoints come from Group 0 service discovery; + process PID, restart generation, and crash-loop state come from + `crowdb-monitor`; browser-only preferences remain in browser storage. None is + copied into either TOML file. +- **Unreleased format replacement:** the current mixed `ConsoleConfig` format is + not a compatibility surface because CROWDB has not released it.

Each log file is limited +to 30 MiB with five rotated files, and warning/error output is also mirrored to +container stderr. `/opt/crowdb/run` and all image paths are never +part of a data backup.

The build + stage uses the repository's pinned Rust, C++, and UI dependency inputs to + produce release binaries and installs the `crowdb-web` static UI under + `/opt/crowdb/ui`; the web service must resolve that packaged runtime + path rather than a build-workspace path. The build must not execute database + initialization or copy any generated disk, topology, Group 0, Group 1, tenant, + catalog, credential, or bootstrap-manifest state into an image layer. The + runtime stage is based on a digest-pinned `ubuntu:24.04`, contains only + required runtime libraries and artifacts, runs as a dedicated non-root user, + and records the source revision and preview version in OCI labels. Build + context excludes local runtime data, credentials, test output, VCS data, and + unrelated build products. +2. Add a dedicated `crowdb-monitor` deployment daemon as the image entrypoint + and PID 1. It owns configuration validation, runtime initialization, child + creation and reaping, process and functional-liveness monitoring, restart + backoff and budgets, readiness aggregation, signal handling, and shutdown. It + classifies the durable root before mutation, validates every path, address, + capacity, and secret input before starting storage, and never interprets S3 + or Iceberg requests. A replacement child may start only after the prior PID is + reaped and its listeners are no longer serving; the daemon never permits + overlapping owners of one durable identity. +3. Drive the minimum topology through existing management and client APIs only + at runtime. For an empty data root, `crowdb-monitor` durably records a + versioned `Initializing` manifest with generated stable identities, starts the + minimum dependencies needed for management calls, and creates one rack, one + node, one disk group, four stable disk identities backed by the 16 GiB sparse + files `/opt/crowdb/data/disks/disk-0001.img` through `disk-0004.img`, one + DiskDB instance, one `unsafe_colocated` ChunkDB placement domain, one Chunk-KV + service, one S3 tenant, one active Iceberg catalog, and one KV server with + exactly two groups. + Group 0 is the system group and owns topology, service, and other system + authority; Group 1 is the data group and owns user data routed by the preview. + Each step is replay-safe and advances the manifest until it is durably + `Ready`. If startup finds `Initializing`, the monitor resumes with the same + identities and operation inputs. If startup finds `Ready`, it makes no create + call: it starts services against existing state and validates both group + identities, roles, bindings, tenant, catalog, and disk before readiness. A + non-empty root with a missing, corrupt, unsupported, or conflicting manifest + fails without creating, replacing, or truncating anything. +4. Start dependencies in probe order: the KV server with ready Group 0 and Group + 1, DiskDB and DiskIO, ChunkDB, Chunk-KV, S3 and Iceberg access processes, then + `crowdb-web`. Each stage has a bounded deadline and emits a diagnostic naming + the failed component. Partial startup never reports ready. On crash or failed + liveness, `crowdb-monitor` first marks the instance unready, stops affected + dependents, restarts the failed layer, revalidates its durable authority, and + then restarts dependents in this same order. Internal management, RPC, and + health listeners bind only to the container network namespace and are not + declared as public image ports. +5. Configure `crowdb-access-server` with normal S3 authentication on + `0.0.0.0:16000`, `crowdb-iceberg` with its independent authenticated catalog + and native FileIO listener on `0.0.0.0:8181`, and `crowdb-web` on + `0.0.0.0:14000`. The quick start maps these ports one-to-one and uses + `http://localhost:16000`, `http://localhost:8181`, and + `http://localhost:14000`. `CROWDB_ICEBERG_PUBLIC_URI` defaults to the local + Iceberg URI and is the one documented override when a remote hostname, + reverse proxy, or different host-port mapping changes the client-visible + address. S3 buckets and credentials do not select or authorize Iceberg + resources. +6. Make authentication automatic but explicit. On a fresh volume, + `crowdb-monitor` generates the S3 master key, one preview S3 access-key pair, + and four distinct Iceberg read/write/manage/clear bearer tokens required by + the existing services. It writes all server-only material to + `/opt/crowdb/data/secrets/server.env` and writes only client endpoints, region, + S3 access key/secret, and the Iceberg writer token to + `/opt/crowdb/data/secrets/client.env`; both files are owned by the container + user with mode 0600 and are reused unchanged after restart. The local command + `crowdb-monitor credentials show --format env` prints `client.env` only when + explicitly invoked, so the quick start can use + `docker exec crowdb crowdb-monitor credentials show --format env` while normal + startup logs reveal only that command. Authentication is necessary because S3 + requires SigV4 credentials and the Iceberg server requires distinct bearer + roles; automatic generation removes that setup burden without disabling either + protocol boundary. +7. Refactor `crowdb-web` and `crowdb-console-shared` around the configuration + authority contract before shipping the compiled UI. Replace the current mixed + `ConsoleConfig` load with distinct versioned web-process and optional launch + registry models; make `--config` and `--registry` unambiguous; and remove the + old parser, writer, restore path, fixtures, and docs without compatibility + handling. Topology handlers commit Group 0 first and refresh their read model + only after success; they never persist topology + locally or ignore a Group 0 failure. Startup uses configured seeds to load + Group 0 and service discovery rather than calling local + `restore_persisted_topology` once Group 0 exists. In monitor-managed mode the + console has no registry engine, overlays `crowdb-monitor` process/restart state + onto Group 0 service records, and rejects process-lifecycle mutations because + the monitor is the sole process owner. The web UI displays source and stale/ + unavailable status instead of presenting a local fallback as authoritative. +8. Enforce the mounted data-root contract and subtree ownership shown above. + Starting without `/opt/crowdb/data` requires an explicit disposable mode; + otherwise startup fails before writing data. Empty-root detection cannot treat + a non-empty directory as fresh merely because its manifest is absent. Reject + missing-on-non-empty, corrupt, unsupported, or state-conflicting bootstrap + manifests and on-disk layout versions without mutation. The four disk + identities, backing paths, one-zone layouts, and 16 GiB per-disk capacities + are fixed in the first bootstrap manifest; adding, removing, replacing, or + resizing a disk is unsupported in this preview. This preview does not promise + in-place upgrade compatibility until a later requirement defines it. +9. Add container-level liveness and readiness commands. Container liveness + proves `crowdb-monitor` is responsive and its event loop is advancing without + contacting external networks. The monitor separately runs bounded functional + liveness probes for every child rather than treating a PID as healthy. + Readiness checks the web `/healthz`, KV leadership and topology, storage + registration, S3 health, Iceberg `/v1/config`, completion of bootstrap, and + absence of an active restart. Probes use internal least-privilege credentials, + bounded timeouts, per-process failure thresholds, and disclose no secrets. +10. Add a hermetic Docker acceptance harness and pixi tasks for image build and + test. It starts from an empty named volume, waits for readiness, runs AWS CLI + and boto3 object PUT/LIST/HEAD/range-GET/GET against a Parquet fixture, runs + the pinned PyIceberg operations currently enabled by R184, checks the web UI + and API, restarts the container with the same volume, and repeats reads and + catalog loads. It also tests first-start runtime initialization, interruption + and replay after every initialization step, restart with a `Ready` manifest + without creation calls, invalid configuration, unavailable dependency, every + required-process crash and liveness hang, successful monitored restart, + crash-loop budget exhaustion, monitor failure, `SIGTERM`, wrong secrets, + read-only/unwritable volume, and missing, corrupt, incompatible, or conflicting + bootstrap manifest outcomes. +11. Publish a minimal quick start that pins an image tag, maps ports 16000, 8181, + and 14000, mounts one host data path at `/opt/crowdb/data`, configures the + container runtime restart policy for monitor-budget exhaustion, retrieves + generated preview credentials with the explicit monitor command, and includes + independent S3 and Iceberg examples. The compatibility list names exact + tested client versions and operations; pure Parquet-over-S3 results are not + presented as Iceberg conformance. +12. Add separate CI build/test and release workflows. Pull requests build the + amd64 image and run all Docker gates without registry write credentials. A + Git release tag reruns the complete gates for the exact commit, waits for + manual approval, then publishes to the public Docker Hub repository under an + immutable release-version tag, immutable `git-` tag, and moving + `preview` tag. The workflow never emits `latest`, refuses to overwrite either + immutable tag, and attaches a signature, SBOM, and build provenance to the + published digest. arm64 publication is deferred until a later requirement + supplies a Linux arm64 toolchain and the complete Docker E2E matrix. +13. Keep reusable deployment mechanics in the `container/crowdb-monitor` crate + and every single-node decision in `container/single-node-preview`. The + monitor consumes a validated profile to construct its dependency graph, + render configs, bootstrap authorities, and aggregate health; it does not + infer topology from its executable name or Docker environment. Unit tests + exercise the runtime with synthetic profiles, while Docker acceptance uses + only the named single-node profile. Do not create placeholder multi-node or + bare-metal implementations in R187. + +## Dependencies + +- Depends on the delivered S3 baseline R152 through R166 and its restart-safe + object path. R167 multipart upload, R168 shared-object reclamation, R169 shared + chunk-tree GC, and R170 RDMA are not required for the initial image and must + not be implied by its capability claims. +- Depends on R177's native Iceberg authority and the implemented R178 through + R182 functionality. R183 reclamation and the outstanding R184 conformance + gates remain visible limitations. The image may expose only the R184 routes + and client operations that pass the pinned container matrix; it cannot close + or bypass either requirement. R185 caching and R186 ORC validation are not + dependencies. +- Reuses existing process binaries, management APIs, service registration, + health endpoints, runtime-root conventions, and the compiled + `app/crowdb-web/ui` artifact. R187 owns the required `crowdb-web`/ + `crowdb-console-shared` configuration split and Group 0 authority cleanup; + retaining the current mixed `ConsoleConfig` as a container fallback is not + permitted. Missing composition or probe APIs are added to their owning modules + rather than duplicated in shell parsing. +- Reuses `unsafe_colocated` only as the explicit minimum-topology placement + policy. Its loss-of-resource durability limitation must remain visible in the + image metadata, quick start, and UI. +- Requires a Docker-capable `linux/amd64` acceptance runner. If Docker or native + amd64 execution is unavailable in ordinary CI, the pixi test task must fail + with a clear prerequisite message or run in a separately declared amd64 + container job; it must not silently skip release acceptance. +- Public release requires one Docker Hub repository, a protected release + environment holding write credentials and signing identity, and CI support for + attached SBOM and provenance artifacts. Missing or unauthenticated publication + infrastructure blocks release rather than producing an unsigned or partially + described image; pull-request testing remains available without it. + +## Acceptance + +- Given a clean checkout on a `linux/amd64` runner, when the amd64 image is built + twice from identical locked inputs through pixi, assert both builds publish no + arm64 image or multi-architecture manifest and contain the expected release + binaries and UI, pinned Ubuntu runtime, non-root user, and revision labels, but + contain no source/build/secret files or + initialized disk, topology, group, tenant, catalog, or bootstrap state; record + and gate any permitted nondeterministic metadata.

Invariant: + DOCKER-I11. Integration test. +- Given ready Group 0 and any supplied registry path, when monitor-managed + `crowdb-web` starts, assert it rejects the registry path; with no registry it + uses configured seeds, Group 0 topology, service discovery, and monitor runtime + state, never invokes local topology restore, and marks unavailable/stale + sources accurately. Invariant: DOCKER-I11. E2E test. +- Given the repository's former mixed `ConsoleConfig` files, fixtures, restore + calls, and documentation, when the configuration split lands, assert none + remain in production or test paths and no migration, dual-read, fallback, or + alias accepts that unreleased format.

E2E test. +- Given the P0 S3 client matrix and a Parquet object larger than 1 MiB, when AWS + CLI and boto3 upload, list, head, range-read, and download it, assert bytes and + metadata match and the request traverses the normal large-object path. + Invariants: DOCKER-I1 and DOCKER-I2.

 ## Resolved Decisions
 
 - Docker mode does not manage hardware topology or monitor-owned processes.
-  Logical store/group/replica operations remain in scope and require Group 0

-- Docker logical writes reuse the existing Iceberg management bearer token.
-  The public status view stays unauthenticated, while writes require the token;
-  no new credential is generated.

-- **Group 0:** owns racks, nodes, disk groups, disks, stores, groups, replicas,
-  bindings, and the service registry. CLI and Web in every deployment mode use
-  the same Group 0-backed logical store/group/replica read and write flow;
-  deployment mode does not select a different logical operation implementation.
-  CLI and bare-metal Web also share Group 0-backed hardware operations; Web KV
-  routing and status never revive a local topology fallback. Initial Group 0
-  bootstrap alone uses explicit pre-authority intent. On Group 0 creation it
-  transfers and verifies every topology record, then deletes local topology.
-  If transfer is interrupted, only confirmed matching bootstrap intent may be
-  resumed; a mismatch fails visibly without overwriting Group 0. Once Group 0
-  exists, no read or write falls back to local topology, even if Group 0 is
-  temporarily unavailable; inability to determine whether Group 0 exists also
-  fails unavailable rather than assuming a fresh bootstrap. Local deployment
-  records then describe launch policy or process state only, including the S3
-  mini-cluster.
-  Docker mode does not manage hardware topology (racks, nodes, disk groups, or
-  disks) or monitor-owned processes, but permits logical store, group, and
-  replica operations through that shared flow after Web authenticates with the
-  existing Iceberg management bearer token. Bare-metal mode may manage deployment
-  and hardware topology as well. A successful local file write cannot
-  substitute for a failed Group 0 mutation. When Group 0 is unavailable,
-  topology APIs fail unavailable rather than serving or restoring a local copy.
+- **Group 0:** owns the container's CROWDB rack/node/disk identities,
+  ownership and binding maps, stores, groups, replicas, and service registry.
+  The monitor initializes this fixed profile, verifies committed identity and
+  content on resume, and does not keep a second console topology copy. Docker
+  Web reads those records and live registrations through the existing Group 0
+  client path. An unavailable Group 0 fails cluster queries closed; no local
+  topology or process snapshot substitutes for system metadata. Wider
+  CLI/bare-metal convergence is R188.
 - **`crowdb-web.toml`:** is a versioned, non-secret process configuration. It
   contains the web bind address and port, Group 0 management seeds, packaged UI
-  root, monitor status endpoint, log policy, request bounds, and a mode selecting
-  Docker or bare-metal operation. It contains no racks, nodes, stores,
-  groups, replicas, service inventory, PIDs, binary paths, credentials, or SSH
-  material. In this image `crowdb-monitor` renders it at
+  root, monitor status endpoint, log policy, and request bounds. It contains
+  no topology, process PID, binary path, inline credential, or SSH material.
+  In this image `crowdb-monitor` renders it at
   `/opt/crowdb/run/config/crowdb-web.toml` on every start and invokes
   `crowdb-web --config` with that path.
-- **`registry.toml`:** is an optional, versioned bare-metal deployment registry,
-  selected only by a separate `crowdb-web --registry` option. It may map stable
-  Group 0 node/service identities to machine-local connection and launch policy:
-  host, SSH credential reference, binary and service-config path, workspace, and
-  auto-start choice. It stores no topology relationships, stores, groups,
-  replicas, authoritative service endpoint, health, PID, monitor state, UI
-  preference, or inline secret. Docker mode rejects a
-  registry path because `crowdb-monitor` owns every process.
-- **Runtime/UI state:** live endpoints come from Group 0 service discovery;
-  process PID, restart generation, and crash-loop state come from
-  `crowdb-monitor`; browser-only preferences remain in browser storage. None is
-  copied into either TOML file.
-- **Unreleased format replacement:** the current mixed `ConsoleConfig` format is
-  not a compatibility surface because CROWDB has not released it. Remove its
-  parser, writer, restore behavior, fixtures, and documentation in the same
-  change; do not add a legacy-format migration tool, dual reader, fallback, or
-  schema alias. The one-time transfer of current bootstrap intent into a newly
-  created Group 0 is runtime initialization, not support for old mixed files.
-  Existing development files are unsupported inputs and may be deleted.

+### R188: console — Group 0 authority and deployment configuration cleanup
+
+## Status
+
+Deferred until the R187 single-node Docker image is publish-ready. This work
+must not delay the preview image or turn Group 0 into a Docker deployment
+registry.
+
+## Problem
+
+The unreleased `ConsoleConfig` in
+[`design-crowdb-console.md`](../design/console/design-crowdb-console.md)
+currently mixes cluster topology with host, SSH, binary, port, PID, and local
+launch information. CLI and bare-metal Web can write the local file before a
+Group 0 mutation succeeds, and some reads and restart paths still accept that
+file or a monitor cache as topology authority. A second console can therefore
+observe a different cluster, while an outage can resurrect stale topology.
+
+R187's Docker monitor already owns container process supervision; Group 0 owns
+CROWDB system metadata, not container IDs, images, mounts, PIDs, restart
+generations, or machine-local launch policy. Completing a cross-mode console
+rewrite is not a prerequisite for packaging that monitor and the single-node
+profile. The remaining boundary cleanup belongs in this separate requirement.
+
+## Solution
+
+1. Keep Group 0 as the durable authority for CROWDB hardware hierarchy,
+   ownership and binding maps, KV store/group/replica metadata, and service
+   registration. Do not add Docker or bare-metal process deployment records to
+   Group 0. Docker process state comes from `crowdb-monitor`; bare-metal launch
+   policy remains local. Deployment mode changes which lifecycle and hardware
+   controls are allowed, not the meaning of Group 0 records.
+2. Replace the mixed `ConsoleConfig` persistence in
+   `crowdb-console-shared::config`, `crowdb-web`, and `crowdb-cli` with a
+   versioned Web process configuration and a separate bare-metal launch-only
+   registry. Finish wiring the existing `LaunchRegistry` parser to actual
+   bare-metal deploy/restart operations; remove the unreleased mixed
+   parser/writer, topology fields, restore path, fixtures, and fallback rather
+   than adding a compatibility reader. Retain SSH credential references,
+   binary/config paths, workspace, and auto-start policy locally; never persist
+   inline secrets or runtime PID as topology. Docker Web rejects a launch
+   registry and keeps its monitor-owned process path.
+3. Unify CLI and bare-metal Web hardware mutations through Group 0-backed
+   operations in `crowdb-console-shared::ops::hardware`. Confirm writes before
+   updating a read model; preserve conflicts and uncertain results. Docker Web
+   continues to reject hardware and process mutations.
+4. Complete the common Group 0-backed logical store/group/replica flow in
+   `crowdb-console-shared::ops::kv_logical` for CLI and both Web modes. Reconcile
+   lost responses by reading confirmed authority, test multi-node fan-out and
+   rollback, and remove local logical-topology commits. A failed node-side
+   deletion must not erase surviving Group 0 membership.
+5. Replace config-backed monitor refresh, KV endpoint fallback, and
+   physical/deployment topology reads with Group 0 membership and live service
+   registration. A missing or ambiguous live endpoint fails unavailable; a
+   stopped service may still have local launch policy but is not reported as
+   live. Neither a local launch registry nor a monitor cache is an authority
+   fallback during a Group 0 outage.
+6. Keep pre-Group-0 bootstrap intent separate. After creation, verify every
+   committed hardware and logical record and delete the local topology copy.
+   Persist enough bootstrap identity to resume an interrupted transfer, prove
+   already committed content, and reject conflict. Destroy/clean must use
+   confirmed Group 0 state. If nonmember KV processes were launched before
+   Group 0 exists, propagate usable Group 0 seed hints after initialization
+   before treating their registration as live; seed hints are not topology.
+7. Audit the S3 mini-cluster's local `console.toml` and restart path under the
+   same authority boundary. Retain only launch inputs and bootstrap seeds
+   locally after Group 0 cutover; do not replay a local topology copy.
+8. Migrate the verified bare-metal deployment and operations material from the
+   old `doc/user-manual/user-guide.md` into
+   `doc/user-manual/bare-metal-user-guide.md`, organized by KV cluster, chunk
+   layer, and data access servers. State that bare-metal is not yet
+   production-ready. Remove the old combined guide only after its supported
+   material and links are migrated; Docker documentation remains independent.
+
+## Dependencies
+
+- R187 provides the working single-node Docker profile, monitor-owned process
+  state, managed Web baseline, and Group 0-backed system metadata. R187 release
+  readiness does not depend on this cross-mode cleanup.
+- The existing Group 0 schema and `crowdb-kv-client` service APIs remain the
+  authority. If a live registration is absent, operations fail unavailable or
+  wait for registration; local launch policy never substitutes for it.
+- The old mixed console file is unreleased. No on-disk compatibility promise or
+  migration tool is required, but bootstrap replay must not overwrite a
+  confirmed initialized cluster.
+
+## Acceptance
+
+- Given a Docker process restart and a bare-metal process restart, when runtime
+  state is queried, assert Docker PID/restart state comes from the monitor and
+  bare-metal launch policy stays local, while neither appears as Group 0
+  topology. Invariant: deployment state is not sysdata. Integration test.
+- Given a mixed legacy config and valid/invalid launch registries, when Web and
+  CLI start, assert only versioned process and launch inputs are accepted, no
+  local topology is restored, Docker rejects the registry, and inline secrets
+  or topology fields fail validation. Invariant: separated configuration.
+  Integration test.
+- Given two bare-metal consoles and one ready Group 0, when each mutates racks,
+  nodes, disk groups, or disks and a write conflicts or loses its response,
+  assert both read one confirmed result and neither commits a local-first
+  topology change. Invariant: hardware authority. Integration test.
+- Given CLI, Docker Web, and bare-metal Web with the same Group 0, when each
+  performs authenticated logical store/group/replica operations, assert one
+  shared result, correct fan-out/rollback, and no local logical copy.
+  Invariant: common logical authority. Integration test.
+- Given missing, duplicated, or expired registrations and then a Group 0
+  outage, when topology, endpoint, or deployment status is read, assert no
+  stale local endpoint or monitor snapshot is presented as authoritative.
+  Invariant: fail-closed discovery. Integration test.
+- Given a crash before and after each bootstrap commit and before local
+  deletion, when startup resumes, assert it proves identity and committed
+  content, writes only safely missing records, and rejects conflict without
+  overwriting Group 0. Invariant: replay-safe cutover. Integration test.
+- Given nonmember KV processes launched before Group 0 initialization, when
+  Group 0 is created and seed hints are propagated, assert each process
+  registers exactly one live node identity before logical operations use it.
+  Invariant: registration readiness. E2E test.
+- Given a persisted S3 mini-cluster and a Group 0 outage, when it restarts or
+  tears down, assert local launch data cannot recreate or mask old cluster
+  topology. Invariant: no secondary authority. Integration test.
+- Given the two deployment guides and a reader following bare-metal steps,
+  when the reader deploys KV, chunk services, and Iceberg or S3 access servers,
+  assert each layer has a verified setup and health check, the non-production
+  boundary is explicit, and no link targets the removed combined guide.
+  Invariant: deployment guidance follows its implementation. E2E test.

+### R189: access server / Iceberg — Container client and engine workflows
+
+## Status
+
+Deferred until R187 provides a publish-ready single-node image. This is a
+separate client-ecosystem project, not a gate for publishing the non-production
+Docker preview or closing R184's REST/official-SDK acceptance.
+
+## Problem
+
+R184 proves the declared REST protocol with official SDKs and a supported
+subset of the Apache compatibility kit. R187 proves a packaged container with
+PyIceberg and S3 client fixtures. Neither proves that a developer can connect a
+notebook, dataframe library, SQL engine, or distributed compute engine to the
+same image and obtain correct table rows across commits and restarts. A catalog
+endpoint alone is insufficient: clients may require different credential
+delegation, file-location, format-version, and delete-file behavior. Advertising
+untested client compatibility would mislead evaluators of the preview.
+
+The [access architecture](../design/access-server/design-crowdb-access-server.md)
+keeps Iceberg table authority separate from general S3 buckets. This project
+tests clients against that boundary rather than assuming an S3-shaped file URI
+is a normal S3 object.
+
+## Solution
+
+1. Build an isolated, reproducible client harness around the R187 image and
+   `container/single-node-container/tests/`. Pin each client and dependency in
+   Pixi or a locked external image, record its exact version and operation
+   profile, publish only S3/Iceberg/Web ports, and use generated scoped
+   credentials. Tests must not modify the user's persistent volume or accept
+   arbitrary external object locations as native Iceberg files.
+2. Prove the Python notebook/dataframe path first: PyIceberg discovers the
+   REST catalog, writes a small Arrow/Parquet-backed table through its supported
+   FileIO, and reads selected rows and a prior snapshot into Arrow batches and
+   pandas. Test Polars through PyIceberg's conversion separately. Include a
+   notebook-style analysis and a batch-oriented ML/data-processing consumer;
+   distinguish eagerly materialized dataframes from a bounded Arrow batch
+   reader. Keep version and feature claims limited to pinned passing fixtures.
+3. Test a local SQL path with DuckDB's Iceberg REST catalog integration, not
+   only a static metadata-file scan or a PyIceberg-to-DuckDB in-memory copy.
+   Verify catalog discovery, delegated file access, SELECT and a supported
+   write if the pinned client and current CROWDB profile permit it. If its
+   required FileIO or authentication contract is unsupported, record the exact
+   first divergence and a separate implementation dependency; do not expose a
+   misleading success recipe.
+4. In the separately provisioned engine project, pin Spark, Flink and Trino
+   profiles against the same container and run the capabilities each client
+   actually supports: namespace/table lifecycle, append/read, schema or
+   partition evolution, snapshots/time travel, row-level deletes, and restart.
+   Compare one engine's committed rows with another engine and PyIceberg; do
+   not claim an engine or format version compatible from catalog-only tests.
+   Failures must identify REST, FileIO, format, credential or client behavior
+   without weakening the server's authority and durability contracts.
+   Exercise a cross-tool handoff where one client writes, another reads, and a
+   third verifies the same selected snapshot after a container restart.
+5. Evaluate streaming/ingest as a later scenario, starting with the official
+   Iceberg Kafka Connect sink only after its pinned connector can use the
+   supported REST and FileIO profile. Record its setup and first divergence
+   separately; Kafka infrastructure is not required for the Python/SQL/engine
+   acceptance above. Exercise a simple BI query through a tested SQL engine;
+   do not claim direct BI-tool or catalog compatibility without its own fixture.
+6. Add only passing, reproducible recipes to
+   `doc/user-manual/docker-single-node-user-guide.md`. Maintain a client
+   capability matrix with tested versions, read/write scope, known exclusions,
+   and links to executable fixtures. Label the image and all examples as
+   development/test, not production data storage or upgrade-stable service.
+   A direct Parquet file read or generic S3 object operation does not establish
+   Iceberg catalog, snapshot, or table-row compatibility.
+
+## Dependencies
+
+- R187 supplies the image, volume/port contract, monitor, credentials, and
+  container test baseline. R184 supplies REST/SDK conformance and the declared
+  capability profile. This requirement does not block either one's completion.
+- R177's deferred cross-engine acceptance moves here. R186 ORC, R185 caching,
+  production durability, and general S3 bucket semantics are not prerequisites;
+  unsupported operations remain explicitly excluded from published recipes.
+- The official [PyIceberg API](https://py.iceberg.apache.org/api/) documents
+  Arrow batches and pandas conversion; the official
+  [DuckDB catalog guide](https://duckdb.org/docs/current/core_extensions/iceberg/catalogs)
+  documents direct REST attachment. These describe client capabilities, not
+  proven CROWDB compatibility. Pin versions before implementation.
+
+## Acceptance
+
+- Given a clean R187 image and isolated volume, when the client harness starts
+  and exits, assert fixed versions, generated scoped credentials, bounded test
+  data, no internal port publication, complete diagnostic artifacts on failure,
+  and no change to another volume. Invariant: reproducible isolation. E2E test.
+- Given a PyIceberg-written Parquet table with multiple snapshots, when Arrow
+  batches, pandas and Polars read a filtered current and historical view before
+  and after container restart, assert identical rows, types and snapshot
+  selection; the batch path does not materialize the whole result at once.
+  Invariant: Python dataframe correctness. E2E test.
+- Given a notebook-style query and a batch-oriented downstream consumer, when
+  each uses the PyIceberg catalog and Arrow batch reader, assert selected rows
+  and types agree with the table snapshot and memory use is bounded by the
+  chosen batch rather than the full table. Invariant: analysis and ML consume
+  catalog-selected data. E2E test.
+- Given a pinned DuckDB Iceberg REST profile, when it attaches CROWDB and
+  queries a PyIceberg-created table, assert rows and catalog identity match; if
+  direct attachment cannot satisfy the declared CROWDB FileIO contract, assert
+  the failure is classified and no direct-DuckDB recipe is published.
+  Invariant: direct SQL claims require proof. E2E test.
+- Given pinned Spark, Flink and Trino profiles with only supported operations,
+  when each writes or reads and another client verifies after restart, assert
+  committed rows, schema, snapshots and supported deletes agree, with every
+  unsupported operation recorded rather than counted as a pass. Invariant:
+  cross-engine interoperability. E2E test.
+- Given a table written by one client and changed by another, when a third
+  client reads before and after container restart, assert the selected snapshot
+  and visible rows agree across clients; reading the underlying Parquet file
+  alone is not counted as a catalog pass. Invariant: cross-tool handoff follows
+  Iceberg authority. E2E test.
+- Given a candidate Iceberg Kafka Connect sink and an isolated event stream,
+  when its REST/FileIO handshake and one append are attempted, assert either a
+  verified end-to-end row result or a documented first unsupported boundary;
+  neither outcome blocks the core client matrix. Invariant: honest ingest
+  compatibility. E2E test.
+- Given a verified SQL engine and a small dashboard-style aggregate query,
+  when the query runs against a catalog table, assert its result matches the
+  selected snapshot; do not claim an untested BI tool connects directly to
+  CROWDB. Invariant: BI recipes use a proven SQL path. E2E test.
+- Given the client recipes and matrix, when a user follows each published
+  example against the pinned image, assert every advertised operation passes
+  and the non-production, no-upgrade and format limits remain visible.
+  Invariant: documentation follows evidence. E2E test.

-# CROWDB Single-Node Preview Plan
-
-Upstream: [R187](../backlog/R187-deployment-single-node-docker-preview.md)
-
-Goal: ship the `linux/amd64` CROWDB Single-Node Preview image with a reusable,
-profile-driven monitor, runtime bootstrap, S3/Iceberg/Web access, restart safety,
-and verifiable release assets.
-
-## Phase 1 — Deployment runtime foundation
-
-- [x] **Profile and layout model**: add the `crowdb-monitor` workspace crate under
-  `container/crowdb-monitor`; define versioned deployment-profile, path, service,
-  dependency, probe, restart, public-endpoint, and bootstrap inputs; validate
-  cycles, duplicate identities/listeners, path escape, missing dependencies,
-  unsupported versions, and profile-owned topology. Keep single-node constants
-  out of the reusable graph/supervision modules. Files:
-  `Cargo.toml`, `container/crowdb-monitor/Cargo.toml`,
-  `container/crowdb-monitor/src/{lib,profile,layout}.rs`,
-  `container/crowdb-monitor/tests/profile_test.rs`.
-- [x] **Single-node profile**: add the named `crowdb-single-node-preview`
-  profile with Group 0/1, four stable 16 GiB file disks, process graph, ports,
-  `/opt/crowdb` paths, probes, log bounds, and public preview labels. Install only
-  this profile in R187; add no future-profile placeholders. Files:
-  `container/single-node-preview/profile.toml`,
-  `container/single-node-preview/templates/*.toml`,
-  `container/crowdb-monitor/tests/single_node_profile_test.rs`.
-- [x] **Manifest state machine**: implement atomic, mode-0600
-  `Initializing`/`Ready` manifest persistence, stable generated identities,
-  exact-profile/config digests, empty-root classification, interrupted-step
-  replay, Ready validation-only restart, and fail-closed handling for unknown or
-  conflicting state. Files:
-  `container/crowdb-monitor/src/{manifest,bootstrap}.rs`,
-  `container/crowdb-monitor/tests/manifest_test.rs`.
-- [x] **Secrets and credentials command**: generate and atomically persist the
-  S3 master key/access pair and four distinct Iceberg bearer tokens, split
-  server/client env files, redact diagnostics, and implement `credentials show
-  --format env` without exposing server-only material. Files:
-  `container/crowdb-monitor/src/{credentials,command}.rs`,
-  `container/crowdb-monitor/tests/credentials_test.rs`. Server master key and
-  four bearer tokens, private file persistence, and explicit client-file retrieval
-  are done. Group 0-backed S3 issuance and `client.env` persistence are
-  invoked from monitor `run` and covered by focused and real-stack tests.
-
-## Phase 2 — Process supervision and health
-
-- [x] **Config rendering**: render all child configs into
-  `/opt/crowdb/run/config` from immutable templates and validated profile values;
-  pass durable/log paths explicitly and prevent secrets from entering command
-  arguments or rendered non-secret configs. Files:
-  `container/crowdb-monitor/src/render.rs`,
-  `container/single-node-preview/templates/*.toml`,
-  `container/crowdb-monitor/tests/render_test.rs`.
-- [~] **PID 1 supervisor**: implement child ownership/reaping, dependency-order
-  start, reverse-order drain, SIGTERM restart suppression, functional probes,
-  readiness aggregation, affected-dependent restart, finite exponential backoff,
-  crash-loop exit, non-overlap fencing, and atomic status/PID output. Files:
-  `container/crowdb-monitor/src/{main,process,probe,supervisor,status}.rs`,
-  `container/crowdb-monitor/tests/supervisor_test.rs`. Bounded probes, atomic
-  status snapshots, child ownership/reaping, TERM/KILL escalation, and bounded
-  per-child logs are implemented. The single-loop supervisor now starts after
-  healthy dependencies, drops readiness on probe failure, restarts affected
-  services with finite backoff, handles SIGTERM drain, and tests exit recovery
-  and budget exhaustion. Dependent cascade and transient-probe recovery tests
-  also pass. A configurable stable-health period now resets the crash-loop
-  budget and logs that transition. Remaining: real-bootstrap staging,
-  PID 1 acceptance and durable-authority revalidation after child recovery.
-  Profile-declared listeners are now fenced after reaping and before replacement;
-  a surviving listener fails the monitor instead of admitting overlap.
-- [~] **Monitor lifecycle log**: persist important bootstrap, readiness, child
-  lifecycle, probe failure, restart, drain, and exhaustion events under durable
-  `log/monitor/`; retain bounded rotation, redact by using fixed event fields,
-  and mirror warning-class transitions to stderr. Event storage and child
-  start/stop plus supervisor readiness, probe failure, restart, drain, and
-  exhaustion logging are implemented. KV bootstrap step start/completion/failure
-  events are connected; disk files, hardware, S3, and Iceberg also log their
-  durable steps. DiskIO, chunk, and Web authority probes now log start,
-  completion, or failure. Full-process log acceptance remains. Files:
-  `container/crowdb-monitor/src/monitor_log.rs`,
-  `container/crowdb-monitor/tests/monitor_log_test.rs`.
-- [~] **Monitor commands**: expose `run`, `liveness`, `readiness`, and credentials
-  subcommands with bounded local operation and stable exit codes for Docker
-  health checks. Files: `container/crowdb-monitor/src/{main,command}.rs`,
-  `container/crowdb-monitor/tests/command_test.rs`. `validate`, `credentials
-  show`, `liveness`, and `readiness` are implemented. `run` now stages KV,
-  disks, hardware, DiskDB/DiskIO, chunk services, S3 credentials, Iceberg
-  catalog, S3/Iceberg listeners, then Web; failed startup drains children and
-  cannot mark readiness. The preflight rejects template digest drift and
-  foreign nonempty roots. Full-process/container acceptance still remains.
-  Liveness now round-trips a local 0700-directory Unix socket instead of
-  treating a fresh status file as proof that bootstrap/event-loop work advances;
-  readiness remains the durable status plus child-health gate.
-
-## Phase 3 — Single-node runtime bootstrap
-
-- [x] **KV bootstrap**: start one `crowdb-kv-server` at the fixed root/ports,
-  create Group 0 through `/system/init`, create Group 1 through management APIs,
-  wait for exact leadership/readiness, and on restart prove both groups' durable
-  identities without issuing creation calls. Files:
-  `container/crowdb-monitor/src/bootstrap/{kv,http}.rs`,
-  `container/single-node-preview/templates/kv.toml`,
-  `container/crowdb-monitor/tests/kv_bootstrap_test.rs`. The existing management
-  API contract is used for Group 0/1, with exact identity/readiness checks,
-  response-loss proof before replay, and validation-only Ready restart. Mock
-  HTTP tests pass and monitor events are verified. A real-process test now
-  starts KV through `Supervisor`, creates Group 0/1 through the management API,
-  shuts down, and validates both after restart. Monitor `run` stages this step.
-- [x] **Four-disk storage bootstrap**: create sparse files without truncating
-  existing bytes; write rack/node/disk-group/four-disk authority to Group 0;
-  render and start DiskDB and DiskIO; validate all stable disk IDs, one-zone 16
-  GiB capacities, registration, and direct per-disk readiness. Files:
-  `container/crowdb-monitor/src/bootstrap/{hardware,storage}.rs`,
-  `container/single-node-preview/templates/{diskdb,diskio}.toml`,
-  `container/crowdb-monitor/tests/storage_bootstrap_test.rs`. Sparse-file
-  provisioning, restart validation, missing/changed disk rejection, and step
-  logging are implemented in `bootstrap/disk_files.rs`. Group 0 rack/node/
-  disk-group/four-disk authority, stable DiskDB owner, and Group 1 bind are
-  reconciled through `HardwareClient` with preflight conflict rejection and
-  real-KV tests in `bootstrap/hardware.rs`. Real DiskDB/DiskIO processes now
-  register their owner in Group 0; the monitor waits for the matching registry
-  record and fsyncs all four disk IDs through DiskIO. The same authority and
-  disk probe pass after a persisted restart. Monitor `run` stages these services.
-- [x] **Chunk services bootstrap**: render/start ChunkDB in explicit
-  `unsafe_colocated` mode and Chunk-KV with metadata Group 1; establish service
-  registry/catalog authority and readiness without enabling split or claiming
-  a failure domain. Files:
-  `container/crowdb-monitor/src/bootstrap/chunk.rs`,
-  `container/single-node-preview/templates/{chunkdb,chunk-kv}.toml`,
-  `container/crowdb-monitor/tests/chunk_bootstrap_test.rs`. The named ChunkDB
-  template now explicitly selects `unsafe_colocated`. Real-process first boot
-  reaches ChunkDB and Chunk-KV readiness with Group 0-issued binding and serving
-  grant. The file-backed O_DIRECT read path now uses an aligned bounce buffer
-  for byte-range requests; a 238-byte RPC regression test and the full
-  KV/DiskDB/DiskIO/ChunkDB/Chunk-KV persisted-restart test pass. Monitor `run`
-  stages both services. A bounded Group 0 registry probe now requires exactly
-  one live matching instance for each service and confirms the bootstrap
-  partition is hosted at its configured owner epoch. The real-process restart
-  test rejects mismatched ChunkDB and Chunk-KV identities before restoring
-  their rendered configs.
-- [x] **S3 credential bootstrap**: after Group 0 readiness, issue one preview
-  user through the existing authority, recover a lost issuance response via
-  `ensure-user`, and use read-only `lookup-user` on Ready restart. Persist
-  `client.env` before advancing the manifest, validate it against Group 0 on
-  restart, and reject a conflict. The focused monitor tests and real S3 stack
-  cover replay. Files: `app/crowdb-access-server/src/{credentials,main}.rs`,
-  `container/crowdb-monitor/src/bootstrap/s3.rs`,
-  `container/crowdb-monitor/tests/access_bootstrap_test.rs`. Verified by two
-  focused monitor tests and the 17-case real S3 full-stack suite.
-- [x] **Iceberg catalog and access listeners**: initialize/activate the
-  catalog with durable UUIDv7 request identities, start authenticated S3 and
-  Iceberg listeners on container ports 8010/80, default client-visible
-  Iceberg URI to host port 80, and validate discovery/health without
-  trusted-network bypass. Wire both bootstrap steps into monitor `run` after
-  the storage services. Files:
-  `container/crowdb-monitor/src/bootstrap/iceberg.rs`,
-  `container/crowdb-monitor/src/main.rs`, and matching real-process tests.
-  The isolated catalog reconciler now reserves durable UUIDv7 operation IDs
-  before management calls, pins the catalog identity in the manifest, proves
-  lost responses through read-only inspection, and rejects foreign or changed
-  catalog state on restart. Mock-process replay and conflict tests pass.
-  The profile now references the Iceberg read token for authenticated
-  `/v1/config` probes; the supervisor passes it from runtime-only environment
-  during start, periodic health, and restart. Focused probe and restart tests
-  pass. Monitor `run` stages catalog and access listeners after storage and S3
-  bootstrap. The real KV/DiskDB/DiskIO/ChunkDB/Chunk-KV test now initializes
-  and activates the catalog, starts the authenticated Iceberg listener, and
-  validates both after persisted restart. Full container acceptance remains in
-  Phase 5.
-
-## Phase 4 — Web authority cleanup
-
-- [~] **Split configuration models**: replace mixed `ConsoleConfig` persistence
-  with versioned `crowdb-web.toml` process configuration and optional bare-metal
-  launch-only `registry.toml`; use distinct `--config`/`--registry` inputs,
-  reject registry in Docker mode, reject inline secrets/topology/runtime
-  fields, and remove the unreleased old parser/writer/fixtures without migration
-  or aliases. Files: `lib/crowdb-console-shared/src/config.rs` and focused child
-  modules, `app/crowdb-web/src/main.rs`, affected config tests. Strict versioned
-  `WebProcessConfig` and `LaunchRegistry` schemas now parse and validate the
-  packaged template, reject unknown topology/secrets and malformed paths, and
-  have focused tests. `crowdb-web --config` now loads the strict process schema
-  before logging or listener bind, uses its bind/log/UI paths, and never loads
-  the legacy mixed file in Docker mode. The unreleased mixed file is
-  rejected as a `--config` input. `--registry` is now a distinct, validated
-  bare-metal-only input; Docker mode rejects it before listener bind. Both
-  process-config modes remain fail-closed on topology APIs while the Group 0
-  projection is unfinished. Bare-metal launch-policy use and removal of the old
-  default parser/writer remain. Legacy bare-metal registry parse errors now
-  abort before listener bind instead of silently falling back to empty state.
-- [ ] **Unified hardware-topology authority**: make CLI and bare-metal Web
-  rack/node/disk-group/disk reads and mutations use the same Group 0 operation
-  path instead of local-first changes followed by ignored sysdata errors.
-  Docker Web keeps these mutations disabled. Preserve conflicts and uncertain
-  results, and use explicit pre-Group-0 bootstrap inputs only during initial
-  cluster creation. Files: `lib/crowdb-console-shared/src/ops/hardware.rs`,
-  `app/crowdb-cli/src/commands/cluster/hardware.rs`,
-  `app/crowdb-web/src/{state,lifecycle,physical}.rs`, and tests.
-  Startup no longer replays local topology when Group 0 is ready or cannot be
-  confirmed. Configured Group 0 seeds now initialize the shared KV client, and
-  `/api/authority` probes Group 0 with the configured request timeout while
-  remaining unavailable until the managed API projection is complete. Remaining:
-  replace local-first hardware mutations and delete obsolete persistence.
-- [ ] **Unified Group 0 logical operations**: make CLI and Web in Docker and
-  bare-metal modes call the same store/group/replica orchestration in
-  `lib/crowdb-console-shared/src/ops/kv_logical.rs`. Resolve node management
-  endpoints from Group 0 service registration with an explicit node identity;
-  do not use `ConsoleConfig.servers`, a Docker profile, or a mode-specific
-  fallback for normal operations. Keep initial Group 0 bootstrap separate
-  because its authority does not yet exist. Remove local store/group/replica
-  record updates and commits from both callers. Preserve fan-out, confirmed
-  metadata writes, conflict and response-loss reconciliation, and fail-closed
-  behavior when Group 0 is unavailable. Tests exercise the same operation from
-  CLI and both Web modes against one Group 0. Files:
-  `lib/crowdb-console-shared/src/ops/{context,kv_logical}.rs`,
-  `lib/crowdb-kv-client/src/service/**`, `app/crowdb-cli/src/commands/kv/logical.rs`,
-  `app/crowdb-web/src/mgmt/{store_ops,group_ops,replica_ops}.rs`, and tests.
-  KV registration now carries a distinct optional node identity; the preview,
-  local deploy, and SSH deploy set it explicitly. Shared logical operations
-  resolve live Group 0 registration instead of local server records, and the
-  CLI/Web no longer commit local store/group/replica copies. Node-side delete
-  failures now retain Group 0 records. Remaining: ambiguous-response
-  reconciliation, multi-node fan-out/rollback tests, and removal of legacy
-  bootstrap/deployment-state dependencies. Group 0 initialization now waits
-  for exactly one live management registration per node before reporting
-  success; KV registration retries promptly until its first success.
-  Bare-metal and CLI test fixtures verify that readiness boundary. An
-  unreachable replica target now fails deletion while retaining Group 0
-  membership, and the leader-removal test verifies this fail-closed behavior.
-- [ ] **Unified topology reads and routing**: remove Web KV endpoint and
-  group-node fallback to `ConsoleConfig.servers/groups`, and remove monitor-cache
-  views that present a local copy as authority. Resolve membership from Group 0
-  and live endpoints from the service registry in CLI and Web; fail unavailable
-  rather than returning stale local topology. Files: `app/crowdb-web/src/{kv,mgmt,physical}.rs`,
-  `lib/crowdb-console-shared/src/ops/context.rs`, `lib/crowdb-kv-client/src/service/**`,
-  and read/leader-change tests.
-  Web KV data-plane requests now check Group 0 replica membership and live
-  KV-server registrations before discovery; they no longer use locally persisted
-  server/group entries as authority; a cache leader hint is accepted only for
-  a Group 0 member with one live registration and a reported store port. The
-  endpoint route now shares that discovery and rejects an unconfirmed leader
-  instead of using a local or first-healthy fallback. Bare-metal Web store
-  list/detail now project Group 0 records using bulk group/replica scans and
-  verified cache leader overlays; cached-only stores fail closed when Group 0
-  is unavailable. The bare-metal Web group list now reuses that Group 0
-  projection. Group and replica detail/list views now start from Group 0
-  membership, query only uniquely registered live management endpoints,
-  and surface unobserved replicas as `unknown` rather than inventing a
-  follower. Remaining: remove config-backed monitor refresh and convert
-  physical/deployment read projections.
-  Non-member KV keepalive now accepts Group 0 management seeds instead of
-  seeding its own RPC port; local and SSH deploys pass the verified Group 0
-  member registrations when the cluster exists. Initial Group 0 hosts deploy
-  before bootstrap, while other nodes deploy afterward. The real-backend
-  `22-kv-topology` Playwright spec passes all five cases with this ordering.
-  KV restart now obtains retained Group 0 connection hints before stopping
-  the old process; Web passes its current runtime PID into the shared restart
-  path. This also supports an all-stopped Group 0 without pretending launch
-  hints are authoritative topology.
-  Real-backend store/group and reconfiguration suites now use the same
-  Group 0-first deployment sequence and pass all six cases. An operator who
-  predeploys nonmember servers before Group 0 initialization still needs a
-  post-init seed refresh; do not count those nodes as registered until that
-  propagation exists.
-- [~] **Bootstrap and teardown authority boundary**: keep initial Group 0
-  bootstrap intent separate because Group 0 does not exist yet. After creating
-  Group 0, transfer and verify every hardware/store/group/replica record, then
-  remove local topology; only launch policy remains. Persist a bootstrap
-  identity/phase sufficient to resume an interrupted transfer without treating
-  arbitrary old local state as authority. On restart, prove identity and
-  committed content, write only safely missing records, and fail on conflict;
-  never serve local topology once Group 0 exists, including during an outage.
-  Make destroy/clean read live Group 0 state, not a `ConsoleConfig` snapshot.
-  Test crash before/after each commit and before local deletion. Files:
-  `lib/crowdb-console-shared/src/ops/cluster.rs`,
-  `app/crowdb-web/src/mgmt/{cluster_init,topology}.rs`, CLI cluster commands,
-  bootstrap-state storage, and failure/restart tests. The preview bootstrap now
-  records its profile-owned store, groups, and replicas in Group 0 with full
-  preflight, read-after-write reconciliation, and restart validation. The
-  legacy bare-metal initial transfer and destroy/clean authority path remain.
-- [ ] **Deployment records are not topology**: use `registry.toml` only for
-  bare-metal launch policy and monitor state only for Docker process lifecycle.
-  CLI/Web service deploy, restart, stop, and DiskDB proxy status must discover
-  live endpoints from Group 0 service registration, not persisted `ServerEntry`
-  or PID fields. Keep deployment control mode-specific, not a second logical or
-  hardware authority. Files: `lib/crowdb-console-shared/src/ops/kv_server.rs`,
-  `app/crowdb-cli/src/commands/kv/server.rs`,
-  `app/crowdb-web/src/{lifecycle,diskdb,mgmt}.rs`, and tests.
-- [ ] **S3 mini-cluster authority audit**: keep its local data-dir record for
-  process restart and bootstrap seeds only. Transfer any pre-Group-0 topology
-  intent into Group 0 and delete that local topology after verification. Once
-  Group 0 exists, route normal hardware/logical queries and operations through
-  the same shared Group 0 path without local fallback. Files:
-  `lib/crowdb-console-shared/src/ops/s3.rs` and mini-cluster restart tests.
-- [x] **Web logical authorization**: pass the existing Iceberg management
-  token to Docker Web through its environment and require an exact bearer
-  token before any logical write RPC in either Web mode. Keep public status
-  reads available and hardware/process writes unavailable in Docker even with
-  the token. Add malformed/missing/wrong-token and forbidden-hardware tests;
-  do not expose logical write routes until the shared operation passes.
-- [ ] **Docker-mode Web UI**: start `crowdb-web` from rendered config, overlay
-  monitor PID/restart/crash state on Group 0 service records, disable conflicting
-  lifecycle controls, and show source/unavailable state in the UI. Add focused
-  Rust, component, and real-backend Playwright assertions. Files:
-  `app/crowdb-web/src/**`, `app/crowdb-web/ui/src/**`, and the matching
-  `app/crowdb-web/ui/e2e/flows/*` specs. The monitor now also requires
-  `/api/authority` to affirm `source=group0` and `available=true` before
-  publishing readiness, so the existing web health-only behavior cannot
-  falsely mark the preview ready. A managed Web process now reports unavailable
-  authority and rejects all `/api/*` topology reads/writes rather than serving
-  empty local state or accepting local-only mutations. The Group 0 projection
-  and UI overlay are in progress. Docker-mode hardware-topology and process
-  mutations remain forbidden; logical store/group/replica operations must not
-  be rejected by mode once the Group 0 write path is implemented. Managed
-  logical reads and writes now use Group 0 directly; writes require the exact
-  management bearer. The preview UI has in-memory token entry and logical
-  controls, with a focused browser assertion. Bare-metal hardware/process
-  management and full real-backend UI acceptance remain. Managed authority
-  now waits for live KV management registration for each hosted store node,
-  preventing a ready response before logical writes can resolve endpoints.
-
-## Phase 5 — Image and local acceptance
-
-- [x] **Image assets**: add the digest-pinned Ubuntu 24.04 amd64 multi-stage
-  Dockerfile, `.dockerignore`, non-root user, `/opt/crowdb` install layout,
-  immutable UI/templates/profile, entrypoint, OCI labels from `VERSION`, exposed
-  public ports only, and monitor health checks. Files:
-  `container/single-node-preview/{Dockerfile,.dockerignore}` and build support.
-  Default invocation maps host `80:80` for Iceberg. Enable binding container
-  port 80 for the non-root Iceberg process without running the whole image as root.
-  Built `crowdb-single-node-preview:dev` with digest-pinned Ubuntu 24.04,
-  release binaries and packaged UI, UID 10001, and file-scoped port-80
-  capability. The image smoke verifies the profile, binary loading, labels,
-  capability, and default anonymous-volume declaration. Source ports changed to
-  S3 8010 and Web 8080. The previous image is retained under its backup tag;
-  the rebuilt image passes smoke and the complete container E2E suite.
-- [x] **Pixi tasks**: add `build-docker-preview` and `test-docker-preview`, include
-  the monitor in workspace build/test coverage, and keep Docker prerequisite
-  failures explicit. Files: `pixi.toml`, task-coverage configuration/tests.
-  Both tasks run through Pixi; the monitor is assigned to `test-monitor` and
-  `test-server`. Test-task coverage and monitor tests pass.
-- [x] **Container E2E**: test empty boot, directory/permission contract,
-  credentials retrieval, AWS CLI/boto3 Parquet PUT/LIST/HEAD/range-GET/GET,
-  pinned PyIceberg operations, web health/status, SIGTERM/recreate persistence,
-  interrupted bootstrap, every child crash/hang, crash-loop exhaustion, monitor
-  failure, invalid manifests/config, and internal-port isolation. Files:
-  `container/single-node-preview/tests/**`. The first full-image empty-volume
-  boot exposed DiskIO selecting an invalid io_uring engine when container
-  seccomp rejects ring initialization; `UringEngine` now rejects the invalid
-  ring so the existing blocking fallback can run. The next boot exposed a
-  stale DiskIO registration on interrupted-volume restart; the probe now
-  requires a post-start heartbeat before connecting. Storage and Iceberg/S3
-  initialization then passed, but the Web Group 0 snapshot found no store,
-  group, or replica records. The preview now reconciles these records before
-  starting storage dependents; a bounded Web startup check keeps monitor status
-  fresh while waiting.
-  A repeatable boot, public endpoint, credential, internal-port, default
-  anonymous-volume, and persisted-restart test is connected to
-  `test-docker-preview`. A fresh-volume run exposed the KV monitor planning a
-  split despite disabled balance; the planner now skips automatic split and
-  transfer when no balance policy exists. The focused domain-monitor tests and
-  E2E check that regression. `pixi run test-docker-preview` now passes all
-  implemented boot, restart, and anonymous-volume cases without publishing.
-  Boto3 Parquet PUT/LIST/HEAD/range-GET/GET and PyIceberg namespace and table
-  create/list/property operations now pass through the container and after a
-  persisted restart. Web logical store create/read/delete with bearer auth
-  also passes through the image. All eight children passed SIGKILL and SIGSTOP
-  recovery checks after DiskIO switched from a TCP-only probe to an RPC Ping.
-  Crash-loop exhaustion, corrupt manifest/profile rejection, and PID 1 death
-  also passed. A real PID 1 kill after a persisted bootstrap step now proves
-  replay on the same volume retains deployment identity, completes all steps,
-  and serves S3, Iceberg, and Web. That test exposed restore-mode reuse of
-  Store 0's persisted RPC port from the allocation pool; restored ports are
-  now claimed before new stores are allocated, with a focused restart test.
-  The rebuilt amd64 image passes release policy, image smoke, and full
-  container E2E without publishing.
-- [ ] **Quick start and operations docs**: document the image name
-  `crowdb-single-node-preview`, ports, one mount, credential command, restart
-  policy, exact limitations, tested clients, backup boundary, and no production/
-  compatibility promise. Files: `README.md`, `doc/user-manual/user-guide.md`,
-  rebuilt `doc/user-manual/user-guide.html`, Docker overview assets.
-
-## Phase 6 — CI and publication
-
-- [x] **PR Docker CI**: add an amd64 build/test job with no registry write
-  credentials and failure artifacts. Files: `.github/workflows/ci.yml`. An
-  isolated `ubuntu-24.04` job now runs Pixi image smoke and container E2E with
-  read-only repository permission and prints Docker diagnostics on failure;
-  upload structured failure artifacts. The container E2E copies monitor and
-  service logs, excluding secrets, into a failure-artifact directory; CI and
-  release verify jobs upload it. The local release-policy gate passes.
-- [~] **Release workflow**: add manual-only, release-tag-targeted publication to
-  `crowdb/crowdb-iceberg`, gated by a protected GitHub environment, with
-  immutable version and `git-` tags, moving `preview`, no `latest`,
-  collision rejection, signature, SBOM, and provenance. The workflow now has
-  only `workflow_dispatch`, verifies the release tag and all required gates
-  without registry credentials, and publishes/signs only after the
-  `preview-release` environment. It fails closed until an administrator enables
-  that protected environment with required reviewers, sets
-  `PREVIEW_RELEASE_ENABLED=true`, `DOCKERHUB_USERNAME`, and `DOCKERHUB_TOKEN`,
-  and enables immutable Docker Hub release tags. No publish has been run.
-  Files: `.github/workflows/release-container.yml` and release config.
-- [ ] **Release acceptance**: test workflow policy, artifact architecture,
-  attached evidence, tag immutability, failed-gate/absent-approval behavior, and
-  exact source revision without using real publication credentials in PR tests.
-  Files: workflow policy tests under `container/single-node-preview/tests/`.
-  Local policy checks now require the full verification suite, no publication
-  credentials in its job, a protected publish environment, and the release
-  enable gate. Image smoke checks amd64, source-revision and version labels.
-  GitHub environment protection and Docker Hub tag immutability still require
-  administrator configuration before manual publication can be accepted.
-
-## Phase 7 — Verification and cleanup
-
-- [ ] **Focused gates**: run monitor unit/integration tests, changed console tests,
-  targeted UI E2E, image build, S3/PyIceberg/container E2E, Rust fmt/clippy, and
-  changed C++ format/tree-lint separately; record confirmed pre-existing failures.
-- [ ] **Permanent architecture**: update the matched deployment/config/console
-  design and user manual with implemented current behavior; index permanent docs.
-- [ ] **Requirement cleanup**: after every acceptance case passes, remove R187,
-  its backlog index entry, and this plan in the final coherent commit.

+# CROWDB Single-Node Container Plan
+
+Upstream: [R187](../backlog/R187-deployment-single-node-docker-preview.md).
+Follow-up: [R188](../backlog/R188-console-group0-authority.md) owns cross-mode
+Console/CLI and bare-metal configuration cleanup.
+
+Goal: finish and verify the `linux/amd64` single-node Docker preview so an
+administrator can manually publish it without waiting for a general Console
+rewrite. Completed implementation is summarized in the R187 requirement and
+git history; this plan tracks only work still needed.
+
+## Boundary
+
+- Group 0 stores CROWDB system metadata: hardware identities, binding and
+  ownership maps, KV topology, and service registration. It never stores
+  container identity, image, mount, PID, restart generation, or launch policy.
+- `crowdb-monitor` owns all Docker child processes and their runtime state.
+  Docker Web reads Group 0 for cluster state and monitor status for process
+  state. Docker Web does not manage hardware topology or child lifecycles.
+- Bare-metal launch registry wiring, old `ConsoleConfig` removal, CLI/Web
+  cross-mode authority convergence, interrupted bare-metal topology transfer,
+  S3 mini-cluster cleanup, and pre-Group-0 nonmember seed propagation belong
+  to R188, not the Docker publication gate. Do not introduce a Docker-only
+  topology or logical-operation implementation to avoid that follow-up.
+
+## Runtime and Web
+
+- [~] **Full-process log and command acceptance**: prove the durable monitor
+  event log records bootstrap, readiness, child restart, probe failure, drain,
+  and exhaustion without secrets; check rotation. Exercise `run`, `liveness`,
+  `readiness`, and `credentials show` in the built container with stable exit
+  codes and bounded operation. Files: `container/crowdb-monitor/src/**`,
+  `container/crowdb-monitor/tests/**`,
+  `container/single-node-container/tests/container-e2e.sh`.
+- [ ] **Crash dump location and retention**: document and test how Linux
+  host `core_pattern`, Docker's core ulimit, and the non-root container affect
+  CROWDB child and PID 1 crashes. Cover a plain relative core-file pattern,
+  Ubuntu Apport, systemd-coredump, and Docker Desktop's Linux VM. Choose a
+  bounded, private location under the mounted `/opt/crowdb/data` volume where
+  the host permits file dumps; otherwise report the host collector location
+  and provide explicit setup guidance instead of claiming the volume contains
+  a core. Verify one disposable child crash end to end, retention/cleanup,
+  secret exposure, and symbolization against the exact binary build. Do not
+  change the host-wide `core_pattern` from inside the container. Files:
+  `container/single-node-container/{Dockerfile,entrypoint.sh,tests/**}`,
+  `container/crowdb-monitor/src/**`,
+  `doc/user-manual/docker-single-node-user-guide.md`.
+- [ ] **Docker Web read model**: finish the managed-mode Web view using Group 0
+  for CROWDB topology and live service registration, and monitor status for
+  process health/restart state. Show source and unavailable state rather than

+
+## Release Readiness
+
+- [ ] **Fresh image acceptance**: build a new amd64 image from the final
+  revision after the image-size task and run image smoke plus the full container
+  E2E on an empty volume and a persisted restart. Recheck S3 Parquet
+  PUT/LIST/HEAD/range-GET/GET,
+  PyIceberg namespace/table operations, Web access, generated credentials,
+  anonymous and named volumes, public ports 80/8010/8080, internal-port
+  isolation, failure/restart behavior, and non-root operation. Preserve the
+  existing image tag until the replacement passes. Files:
+  `container/single-node-container/{Dockerfile,tests/**}`, `pixi.toml`.
+- [ ] **Release policy acceptance**: verify the manual-only workflow publishes
+  only `crowdb/crowdb-iceberg-single-node` `linux/amd64` from the exact release-tag
+  revision, keeps immutable version and `git-` tags, moves only
+  `preview`, never emits `latest`, and attaches signature, SBOM, provenance,
+  and failure artifacts. Test failed verification, absent approval/gate, and
+  existing-tag rejection without registry write credentials. Files:
+  `.github/workflows/{ci,release-container}.yml`,
+  `container/single-node-container/tests/release-policy.sh`.
+- [ ] **Administrator release prerequisites**: before a real manual publish,
+  create or verify the `crowdb/crowdb-iceberg-single-node` Docker Hub repository
+  and confirm the protected `preview-release` GitHub environment has required
+  reviewers, `PREVIEW_RELEASE_ENABLED=true`, `DOCKERHUB_USERNAME`, and
+  `DOCKERHUB_TOKEN`; enable immutable release tags in Docker Hub. These are
+  external settings, not repository code. Do not publish automatically or
+  claim a completed public release before the manual workflow succeeds.
+- [ ] **Docker single-node guide**: create
+  `doc/user-manual/docker-single-node-user-guide.md` for the image name, one
+  mounted volume, ports, credential command, restart policy, tested Iceberg and
+  S3 clients, limitations, backup boundary, and non-production/no-upgrade
+  promise. Link it directly from `README.md` and `doc/doc_index.md`; update the
+  HTML generation path and Docker overview assets. Keep the existing
+  `user-guide.md` until its bare-metal content is migrated and verified under
+  `bare-metal-user-guide.md`; that later migration is not a Docker release gate.
+  Files: `README.md`, `doc/doc_index.md`, `doc/user-manual/**`.
+
+## Deferred Footprint Experiments
+
+These are optional, non-blocking experiments after the current image passes
+the release gate. Change `pixi.toml` and `pixi.lock` only after choosing a
+source and reproducible build for static Folly: the locked conda-forge `folly`
+package supplies `libfolly.so`, not `libfolly.a`.
+
+- [ ] **Folly removal comparison**: first evaluate replacing the RPC pending
+  map with a lock-free design preserving
+  collision handling, cancellation, timeout, and concurrent completion
+  semantics. Benchmark contention and latency before changing the hot path;
+  never substitute a mutex-protected map solely to reduce image size. Success
+  means removing Folly and its dependency closure from the image, not removing
+  every Boost or other library used independently elsewhere. Files:
+  `lib/crowdb-rpc/include/crowdb-rpc/client/client.h`,
+  `lib/crowdb-rpc/src/client/**`, `lib/crowdb-rpc/tests/**`,
+  `lib/crowdb-rpc/CMakeLists.txt`, `pixi.toml`, `pixi.lock`.
+- [ ] **Static Folly comparison**: if keeping Folly is preferable after the
+  pending-map evaluation, build a pinned Folly source revision as a static
+  archive through Pixi, link the existing `ConcurrentHashMap` use, and measure
+  the complete image and `crowdb-diskio` dependency closure against the
+  dynamic build. Require an equal or smaller image, no new unresolved symbols,
+  all affected C++ tests, and container E2E before switching the default. Do
+  not assume static linking reduces size; retain the dynamic path until
+  measured. Files: `pixi.toml`, `pixi.lock`, `lib/crowdb-rpc/CMakeLists.txt`,
+  `container/single-node-container/**`.
+- [ ] **Rust binary comparison**: preserve usable CROWDB function names and
+  source-line diagnostics before pursuing size reductions. First evaluate
+  line tables for CROWDB-owned crates only, C++ `-g1`, and separate versus
+  bundled symbols; verify a real container crash can be symbolized from the
+  exact image revision. Compare the complete image size before deciding; keep
+  debug information and core dumps if the size is acceptable. Do not apply
+  `strip --strip-unneeded` to CROWDB binaries as a default optimization. Then
+  measure `lto="thin"` versus `lto="fat"`,
+  `codegen-units=1`, `opt-level="s"` versus `"z"`, and `panic="abort"`
+  separately, including request latency, crash diagnostics, and release build
+  time. The current release profile uses Cargo defaults:
+  `opt-level=3`, no cross-crate LTO, 16 codegen units, `panic="unwind"`, and
+  no DWARF. Do not enable dynamic Rust standard-library linking without a
+  portability and total-image-size comparison across all eight Rust programs; a
+  shared Rust standard library would not automatically share application
+  crates. Files: `Cargo.toml`, `pixi.toml`,
+  `container/single-node-container/collect-libs.sh`.
+
+Current baseline: packaged `crowdb-iceberg` is 22,179,480 bytes; its `.text`
+is about 13 MiB and `.symtab` plus `.strtab` about 4 MiB. Packaged binaries
+currently use `strip --strip-debug`, so DWARF line tables are absent while the
+normal symbol table remains. Cargo release also defaults to no debug info; the
+builder's original Rust artifacts therefore do not provide release line tables.
+For `crowdb-monitor`, the no-DWARF release binary was 11,803,832 bytes.
+Enabling `line-tables-only` for all dependencies made it 88,084,496 bytes;
+compressing those debug sections with zlib made it 27,761,104 bytes. This
+large per-binary increase has not been extrapolated to the complete image.
+The experiment enabling line tables only for the CROWDB-owned crate was
+interrupted at the user's request and remains unmeasured.
+On a disposable copy of `crowdb-iceberg`, `strip --strip-unneeded` reduced
+22,179,480 to 18,056,944 bytes, but this is **not** an approved image change
+because it removes useful CROWDB symbols. The
+dynamic Folly library is about 7.4 MB after
+stripping; Boost.Regex pulls in about 39 MB of ICU libraries. Removing the
+unused Regex export from the Folly link interface eliminated
+`libboost_regex.so` from the local `crowdb-diskio` ELF dependency list and
+passed the 128 DiskIO C++ tests, but the container image has not yet been
+rebuilt with that change.
+
+## Final Gates and Cleanup
+
+- [ ] **Focused gates**: run monitor unit/integration tests, affected Docker
+  Web/component/Playwright tests, image smoke and container E2E, S3 and
+  PyIceberg client acceptance, Rust fmt/clippy, and changed C++ gates
+  separately; diagnose failures without weakening assertions or adding
+  caller-side retries. Record exact passed commands and confirmed unrelated
+  failures in this plan.
+- [ ] **Permanent Docker architecture**: update only the matched deployment
+  and configuration architecture to reflect the shipped container boundary;
+  leave cross-mode Console architecture changes to R188. Reconcile the user
+  manual with the quick-start task rather than editing it ahead of the user's
+  structure decision.
+- [ ] **Requirement cleanup**: after every R187 acceptance case is satisfied
+  and the image is publish-ready, remove R187 and its backlog index entry and
+  this temporary plan in one coherent final cleanup commit. R188 remains open.
+
+## Current Evidence
+
+- Checkpoint gates on 2026-09-27 passed: `pixi run rs-fmt-check`,
+  `pixi run rs-lint`, `pixi run test-monitor`, `pixi run test-console-shared`,
+  `pixi run tree-lint`, `pixi run test-rpc-ct` (71 tests), and
+  `pixi run test-diskio-ct` (128 tests). Tree lint exited zero with warnings
+  in unchanged C++ sources; no C++ source formatting changed. Release-policy,
+  image-smoke and container-e2e scripts passed through Pixi on image
+  `sha256:5cc4ba103df8615061d6c00a49c8bb68f49e2ee208a83d187ccfd10eb8153780`
+  (298,967,926 bytes). Its source label predates this checkpoint commit;
+  final-image acceptance still requires a rebuild from the final revision.
+
+- Recovery authority acceptance passed on the rebuilt image: supervisor
+  readiness remains false after a child restart until the persisted manifest,
+  Group 0, storage, credentials, catalog, and Web authority are revalidated.
+  The container E2E covered all-child crash/hang recovery, persisted-volume
+  restart, monitor-death replay, crash-loop exhaustion, and rejection of a
+  changed durable credential identity. `pixi run rs-fmt-check`,
+  `pixi run rs-lint`, the focused supervisor test, image smoke, and the full
+  container E2E passed.
+- The existing `crowdb-single-node-preview:dev` image passed release policy,
+  image smoke, full container E2E, S3/PyIceberg client operations, persisted
+  restart, all-child SIGKILL/SIGSTOP recovery, crash-loop exhaustion, and PID 1
+  replay. This is evidence for the previous revision, not a final-image gate.
+- Image-size work is complete: the prior image was 484,206,563 bytes and the
+  rebuilt `crowdb-iceberg-single-node:dev` is 298,882,134 bytes. Runtime
+  binaries and required libraries have debug sections removed; staging the
+  capability change in the same layer avoids a 23.5 MB copy-up. Image smoke
+  enforces a 325 MB regression ceiling. Release policy, image smoke, and the
+  full container E2E passed on the rebuilt image; a final publishable revision
+  still needs the release gates.
+- Managed Web already reads logical topology from Group 0, requires the
+  management bearer for logical writes, and denies Docker hardware/process
+  mutations. The complete process-status UI and outage presentation still
+  need acceptance.
+- PR Docker CI builds/tests without registry credentials and uploads failure
+  logs. The release workflow is manual and fail-closed, but public publication
+  has not run and administrator settings remain external.
+

 ## Tests
 
-- Unit: profile/layout/manifest/credentials/render/supervisor/config schema and
-  release-policy tests.
-- Integration: bootstrap replay, Group 0/1, four disks, service graph, Web
-  authority, process restart, filesystem and secret boundaries.
-- E2E: built amd64 image, S3 clients, PyIceberg, visible Web UI, persistence,
-  signals/faults, readiness, and internal-port isolation.
-- Gates: `pixi run build-docker-preview`, `pixi run test-docker-preview`,
-  `pixi run -e s3-e2e test-boto3-e2e`,
-  `pixi run -e iceberg-e2e test-pyiceberg-e2e`, `pixi run test-console`,
-  `pixi run test-console-ui`, `pixi run rs-fmt-check`, `pixi run rs-lint`, and
-  changed C++ gates when applicable.
-
-## Resolved Decisions
-
-- Docker mode does not manage hardware topology or monitor-owned processes.
-  CLI and Web in both modes use one Group 0-backed logical store/group/replica
-  flow. Bare-metal mode may manage deployment and hardware topology.
-- Web logical writes reuse the existing Iceberg management bearer token in
-  both modes. Public status remains unauthenticated; no new credential is
-  generated.
+- Unit: `pixi run test-monitor`, focused managed Web tests, and
+  `pixi run bash container/single-node-container/tests/release-policy.sh`.
+- Integration: `pixi run -e s3-e2e test-boto3-e2e` and
+  `pixi run -e iceberg-e2e test-pyiceberg-e2e`.
+- E2E: `pixi run build-single-node-container`, `pixi run test-single-node-container`,
+  targeted Playwright through `pixi run`, then `pixi run test-console-ui`.
+- Packaging: image smoke verifies the 325 MB ceiling in CI.
+- Style: `pixi run rs-fmt-check`, `pixi run rs-lint`; if C++ changes,
+  `pixi run tree-lint`, changed-format check, and affected C++ tests.

+  `official_catalog_creates_commits_upgrades_stages_and_refreshes_native_credentials`,
+  and the official create/update/snapshot fixtures compare canonical metadata.
+  `TestIcebergVersionRows` reads actual rows before and after adjacent upgrades,
+  reads historical snapshots, expires them logically, and reloads after restart.
+- **Selected data and deletes:** `TestIcebergSelectedFiles` rejects mismatched
+  selected uses of identical uploaded bytes, reads the original row, verifies
+  equality-delete visibility and reads the historical snapshot. Canonical file
+  validators separately cover position deletes, v3 lineage, deletion vectors,
+  defaults, nested/variant types, integer encodings and nullable values.
+- **Statistics:** `TestIcebergCatalogWrites` and the official partition-statistics
+  fixtures cover publication, replay, evolution and staged creation. Historical
+  omissions follow the explicit compatibility rules described above.
+- **Discovery and authorization:**
+  `discovery_uses_installed_routes_and_unsupported_paths_leave_no_record` and

+  supported cases: namespace create, basic table create, rename, drop,
+  missing-table drop and table list. This is not a full-kit pass. Other cases
+  assume register/views or local filesystem locations that the native authority
+  deliberately rejects. Custom SDK fixtures are not described as kit results.
+- **Large logical files:** `tib_address_space_range_reads_keep_fixed_windows_and_small_authority`
+  and `tib_reclamation_progress_serializes_a_bounded_resumable_cursor` use a

-### R177: access server / Iceberg — Native Iceberg storage blueprint
-
-## Problem
-
-CROWDB has Chunk-KV, chunk storage, and an S3 protocol, but it does not yet have an
-Iceberg authority. Treating Iceberg as ordinary S3 objects would lose the catalog
-name hierarchy, atomic table commits, immutable metadata and data files, snapshot
-reachability, and spec-defined conflict behavior. It would also allow general S3
-overwrite and delete rules to violate the Iceberg table specification.
-
-The implementation needs one program contract before catalog, namespace, table,
-file, reclamation, REST, and cache work can proceed independently. This requirement
-owns that contract and every decision shared by R178 through R185. The permanent
-architecture is [Native Iceberg Storage](../design/access-server/iceberge/design-crowdb-iceberg.md),
-and the backed-up Apache specifications under `doc/design/access-server/iceberge/` are the
-normative protocol and format references.
-
-## Solution
-
-### 1. Core milestone
-
-The first milestone implements one active catalog, multipart namespaces, table
-CRUD and rename, Iceberg format v1, v2, and v3 metadata and files, optimistic table
-commits, snapshots and references, native immutable file storage, and an
-Iceberg-owned S3-shaped FileIO surface. Each format version has separate
-parse/read/create/write capabilities. The implementation supports the spec-defined
-v1-to-v2 and v2-to-v3 upgrades only after validating every intermediate invariant.
-
-The format profile includes schema, partition-spec, and sort-order evolution;
-sequence numbers and row-level deletes; row lineage, deletion vectors, default
-values, and v3 types and encodings; snapshot references and retention metadata;
-statistics and partition statistics; and the Avro, Parquet, ORC, and Puffin rules
-needed by those features. Optional behavior is capability-gated where the table
-spec permits it. A server must not advertise write support for a version while
-ignoring a mandatory field, inheritance rule, validation, or file encoding.
-
-The initial functional checkpoint selects Parquet data/delete files and Puffin
-deletion vectors. Selected ORC validation is explicitly deferred to R186 by user
-decision; ORC byte storage is not a selected-file validation capability. ORC is
-not a prerequisite for this checkpoint, and unsupported selected formats fail
-explicitly. This narrows the initial checkpoint, not the eventual format profile.
-
-The milestone does not advertise views, multi-table transactions, register-table,
-server-side scan planning, multiple active catalogs, tenants, or warehouses.
-Unsupported endpoints and optional features return the precise standard
-unsupported response and perform no mutation.
-
-The user approved a foreground functional checkpoint before reclamation. R179
-through R183 are complete; continue the remaining R184 conformance gates. This
-does not complete the original correctness milestone early. Reclamation requires
-durable positive proof, retention and pins; the worker is opt-in, and unsupported
-shared-range deletion retains pending work rather than claiming reclaimed space.
-Ownership and recovery evidence survive until candidate discovery.
-The functional checkpoint uses existing provisioned disk capacity: insufficient
-eligible space prevents new chunk allocation. It requires no separate Iceberg
-quota or pre-full write-stop policy. Full-capacity failure/recovery acceptance
-belongs to reclamation; per-request bounds do not bound retained
-storage. No mandatory semantics of an advertised version are deferred.
-
-### 2. Authority hierarchy
-
-```text
-system root -> active CatalogId/activation epoch
-  -> catalog authority
-     -> namespace name index -> NamespaceId -> namespace authority
-        -> table name index -> TableId -> TableHead/current metadata generation
-           -> immutable metadata, manifest, data, delete, and statistics files
-```
-
-- `CatalogId`, `NamespaceId`, `TableId`, and `FileId` are random, non-zero,
-  non-reused 128-bit CROWDB identities. Iceberg's `table-uuid` remains a distinct
-  spec field in table metadata.
-- Name mappings are ordered lookup indexes. Stable-ID records are authoritative;
-  list and load filter mappings whose ID, lifecycle, or name epoch is stale.
-- All Iceberg keys use a versioned `ICE\0` protocol prefix. Resource authorities,
-  indexes, and operation payloads live below their CatalogId. A separate bounded
-  system scope holds the active root, management operations/audit, and REST
-  idempotency bindings that must survive catalog replacement. System records never
-  provide a resource lookup path into a retired catalog.
-- Chunk-KV stores bounded authorities, mappings, heads, operation state, and file
-  records. Chunk storage owns all non-inline file bytes. Disk, EC, placement, and
-  node identities never enter Iceberg metadata or locations.
-- The immutable standard table metadata JSON plus the `TableHead` that selects it
-  are the recoverable table-state authority. Binary projections are disposable,
-  generation-qualified accelerators.
-
-### 3. Program invariants
-
-- **ICE-I1 — Stable identity:** rename never changes a CatalogId, NamespaceId,
-  TableId, FileId, metadata location, or committed bytes.
-- **ICE-I2 — One authority:** an index, cache, projection, or notification cannot
-  publish or repair catalog state; it must validate against its stable authority.
-- **ICE-I3 — Atomic generation:** one successful commit performs one `TableHead`
-  compare-exchange that selects one complete immutable metadata generation.
-- **ICE-I4 — Immutable files:** a published canonical location always resolves to
-  the same length, digest, and bytes and cannot be overwritten.
-- **ICE-I5 — Bounded work:** no authority value contains unbounded children; every
-  request, scan page, stream window, projection, operation, retry, and GC batch has
-  independent byte, item, and concurrency limits.
-- **ICE-I6 — Recoverable mutation:** a durable request identity, request digest,
-  phase, and result make response-loss retry safe on another Access Server. Reuse
-  of one identity with different input fails.
-- **ICE-I7 — Domain clear:** after clear completes, no new request, cache entry,
-  credential, location, or resource retry can expose retired catalog resources.
-  Authorized management status, audit, and result replay may identify the retired
-  CatalogId without granting access to its resources.
-- **ICE-I8 — Spec honesty:** only implemented endpoints and format capabilities are
-  advertised; unknown, disabled, or lossy requirements and updates fail closed.
-- **ICE-I9 — Protocol ownership:** the Iceberg FileIO surface shares low-level
-  storage clients with S3 but never uses general S3 bucket/object authority.
-- **ICE-I10 — Lock-free hot path:** implementations add no catalog-wide or global
-  cache lock to lookup, load, commit, or file streaming.
-
-### 4. Requirement decomposition and order
-
-1. R178 establishes the library, active catalog domain, management safety, stable
-   key/value envelope, server lifecycle, and `/v1/config` baseline.
-2. R179 is complete: namespace authority, bounded standard REST operations,
-   child/drop fencing, official-client boundary acceptance and native restart.
-   Its contract is retained in [Native Iceberg Storage](../design/access-server/iceberge/design-crowdb-iceberg.md).
-3. R180 is complete: native immutable files, bounded streaming/range FileIO,
-   durable multipart, delegated credentials and validated generation-local
-   metadata projections, with native fault/restart and official SDK acceptance.
-4. R181 is complete: table identity, v1/v2/v3 metadata validation, lifecycle,
-   load/list/exists, rename/drop and fault/replay acceptance on native files.
-5. R182 is complete: atomic create/staged-create and update commits, requirements,
-   format upgrades, idempotency, conflict classification and native fault recovery.
-6. R183 implements snapshot-aware purge, orphan cleanup, retired catalog cleanup,
-   and bounded reclamation after R180 through R182 define reachability.
-7. R184 completes public REST integration, authentication, endpoint discovery,
-   standard errors, and official-client conformance for the core profile.
-8. R185 adds bounded caches and cross-server invalidation after all identities,
-   epochs, digests, and reclamation fences are stable.
-
-R178 through R184 form the correctness milestone. R185 is a later performance
-milestone and cannot be required for correctness.
-
-### 5. Resolved open issues
-
-All open issues from the former R177-A through R177-D drafts and the former R178
-cache draft are answered here. Child requirements must reference these decisions
-and must not carry independent open questions.
-
-1. **Clear boundary:** a root CAS enters durable maintenance and stops fresh
-   authoritative admission and lease renewal. Existing root leases may still admit
-   old-context work until their fixed expiry. A later root CAS selects the new
-   catalog while maintenance remains active. Clear completes and new-catalog
-   admission opens only after the persisted old-lease, request, and delegated-access
-   deadlines have passed. Lease validity starts before the authoritative root read,
-   never on receipt of a delayed response; delegation cannot extend the bound.
-   Restart and reconciliation preserve those deadlines and configured clock-skew
-   allowance. No instance-registry acknowledgement is required. Reclamation also
-   waits for durable reader and operator pins. R178 owns this state machine.
-2. **Tenant:** the first milestone stores no default tenant and puts no fixed
-   TenantId in hot keys. A later tenant root may map to an active CatalogId without
-   changing catalog-scoped keys.
-3. **Warehouse:** absent or empty `warehouse` selects the sole catalog. Any non-empty
-   value returns the spec-defined `NoSuchWarehouse` response; it is never ignored
-   or created implicitly.
-4. **Retired-catalog safety:** a configurable minimum retention period, clear grace,
-   durable reader pins, and explicit operator pins all fence physical GC.
-5. **Catalog management:** R178 owns authenticated initialize/status/rename/clear
-   management commands. Clear requires a dedicated privilege, explicit destructive
-   confirmation, request identity, and durable audit record; it is not an Iceberg
-   REST endpoint. System-scoped management records preserve the original result
-   across later clears; authentication and digest validation precede replay, and
-   replay precedes checking the current epoch for a new mutation.
-6. **Namespaces:** arbitrary multipart identifiers are supported within configured
-   maximum levels and encoded bytes. Parent listing is complete. Namespace rename
-   is not implemented because it is non-standard; table rename may move across
-   namespaces.
-7. **Namespace drop:** child creation and rename-in first durably reserve their
-   parent/name index entry, then validate the parent through a `Ready` CAS before
-   publication. Drop CASes the parent to `Dropping` before probing those same index
-   ranges. Unresolved reservations prevent an empty proof; recovery settles them
-   before removal. A published child restores `Ready` and returns not-empty;
-   tombstoning requires a complete empty proof. The namespace layer implements
-   bounded recovery and single-key CAS; there is no cross-key transaction or process lock.
-8. **Namespace listing:** scan ordered mappings with bounded over-fetch, validate
-   targets in bounded batches, and bind the opaque continuation token to catalog,
-   parent, parameters, and last scanned key. Stale mappings are omitted. An absent
-   `pageToken` requires one complete response with a null next token; an empty
-   `pageToken` starts pagination. The namespace layer implements bounded spooling
-   and a pre-response 503 on resource exhaustion, never a successful truncated listing.
-9. **Namespace properties:** at most 256 entries; keys and values are UTF-8 without
-   NUL, at most 1 KiB and 8 KiB respectively; the encoded authority is at most
-   64 KiB. Duplicate remove/update keys return the standard 422 response. Mapping
-   name epochs, property revisions, and admission fences are distinct; property
-   updates and failed drops never invalidate an otherwise current name mapping.
-10. **Metadata projections:** metadata JSON gets a durable, disposable,
-    generation-local root/page/child projection. Other parsed format structures
-    stay in R185's memory cache until measurements justify a later requirement.
-11. **Register table:** it is deferred and not advertised because external
-    locations could bypass native CROWDB file authority.
-12. **Table identity:** CROWDB TableId and Iceberg `table-uuid` are distinct and
-    both validated. Neither is derived from a mutable name.
-13. **Rename and drop:** durable operation records reserve destinations and drive
-    a recoverable state machine. `TableHead` name epoch/lifecycle decides validity;
-    stale source or target mappings are filtered. An old name never remains an
-    alias after rename.
-14. **Snapshot loading:** both `ALL` and `REFS` are supported for declared endpoints;
-    each is generated from the same selected metadata generation.
-15. **Format profile:** v1, v2, and v3 each support parse, read, create, and write.
-    Mandatory version-specific semantics are implemented, and v1-to-v2 and
-    v2-to-v3 upgrades are supported. Optional spec features remain separately
-    capability-gated and cannot be silently discarded.
-16. **Canonical location:** use the table prefix
-    `s3://iceberg-/t//`. An exact client-created
-    relative key beneath it maps once to a server FileId. The reserved bucket and
-    prefix are decoded by the Iceberg-owned FileIO service; catalog, namespace, and
-    table names never participate in a location.
-17. **FileIO operations:** the first writable milestone includes immutable PUT,
-    HEAD, one-range GET, create/upload/list/complete/abort multipart, and delegated
-    credentials. Bucket CRUD, overwrite, tagging, lifecycle, and unrestricted
-    DELETE are unsupported.
-    Standard FileIO PUT supplies a location and bytes without Iceberg content
-    type. Native file authority records the verified physical format and may keep
-    semantic kind unbound. A selected manifest or metadata reference supplies
-    semantic usage; load and commit admission validate that usage against canonical
-    bytes before publishing a table head. Filenames and Parquet schemas never
-    decide data versus equality-delete kind.
-18. **Multipart:** multipart is required for the first writable milestone; all
-    sessions, parts, bytes, TTLs, completion, and abort work are durable and bounded.
-19. **Reclamation:** R183 uses generation-indexed candidates plus traversal from
-    retained snapshot roots and metadata logs. It never relies on racing per-file
-    reference counts.
-20. **Projection retention:** metadata projections are generation-local without
-    cross-generation content deduplication in the first milestone. Simple bounded
-    GC is preferred over reference-count and write-amplification complexity.
-21. **Cache clear fencing:** R185 uses the lease-plus-grace clear boundary in item
-    1; notification remains only a latency optimization.
-22. **Cache limits:** R185 defines separate configurable hard caps for every class,
-    queue, batch, fill, and fanout dimension. Initial defaults come from its focused
-    benchmark gate and configuration tests; no class inherits an unbounded or
-    universal one-size value.
-23. **REST retries:** R178 supplies optional UUIDv7 `Idempotency-Key` handling and
-    an advertised retention window before namespace endpoints land. Durable system
-    bindings fix the principal, operation, digest, CatalogId, and activation epoch;
-    retired bindings reject resource replay and cannot initiate work in the new
-    catalog. Final successes and deterministic terminal 4xx are replayed; 5xx do
-    not finalize the operation. Requests without a key have internal recovery
-    identities but no cross-request exactly-once guarantee.
-
-### Confirmed Compatibility Decisions
-
-- **Storage capacity boundary (OI-3, confirmed 2026-09-24):** use the existing
-  disk provisioning/allocation flow, including configured capacity limits for
-  the current file-backed simulated disks. When managed disk capacity cannot satisfy
-  a new chunk, allocation fails naturally; do not add an Iceberg-layer quota or
-  pre-full stop threshold for the current checkpoint. R183 records full-capacity
-  failure safety, later GC and recovery requirements. This settles the capacity
-  policy, not an assertion that unimplemented GC or full-disk tests have passed.
-
-- **Engine testing deferred (OI-2, confirmed 2026-09-24):** do not run Spark,
-  Flink or Trino acceptance in the current implementation phase. R189 owns the
-  separate client/engine project against the single-node container and will pin
-  its engine/version/deployment matrix there. This removes the immediate
-  selection decision, not the outstanding interoperability obligation. Do not
-  advertise untested engine compatibility. R184 REST/official-SDK acceptance
-  can close independently after its own evidence audit.
-
-- **Functional/performance acceptance split (OI-1, confirmed 2026-09-24):**
-  functional correctness uses a bounded runtime profile independently of a
-  subsecond latency target. Preserve the original 500-ms clear/restart timing
-  coverage; move full namespace CRUD assertions to a separate functional test,
-  not out of the suite. A larger functional deadline is not a performance
-  improvement or latency guarantee. Fix only obvious performance bugs with
-  demonstrated root causes and correctness regression tests. Record broader
-  optimization candidates for a later consolidated performance backlog.
-  Do not add test-side retries, suppress failures, weaken assertions, bypass
-  durability/authorization, or change concurrency/clear semantics to fabricate
-  a performance result.
-  A native fault-matrix diagnostic returned one unconfirmed five-second
-  `Store(Client(Deadline))` from the independent verification client after HTTP
-  replay succeeded. Subsequent complete acceptance passed without changing that
-  timeout or adding retries. Track the observation and future routing/transport
-  capture in the [performance follow-up](../working/plan-iceberg-functional-catalog.md#performance-work-to-consolidate-later);
-  do not claim its root cause is fixed or turn it into a new human design choice.
-
-- **Name-mapping interoperability profile (confirmed 2026-09-24):** selected-use
-  admission uses the pinned Java 1.11.0 SDK-safe intersection. Reject colliding
-  dotted paths and multiple ID-less mapping nodes; preserve segmented paths and
-  literal dots for accepted mappings. This is an input-profile restriction, not
-  a claim that the table specification bans those cases. The pinned SDK's
-  [MappingUtil](https://github.com/apache/iceberg/blob/apache-iceberg-1.11.0/core/src/main/java/org/apache/iceberg/mapping/MappingUtil.java)
-  flattens nested paths with dots into unique map keys, and its ID index treats
-  repeated null IDs as duplicates. Thus a literal `a.b` alongside child `b` of
-  `a`, or multiple ID-less imported fields, can fail SDK indexing even when
-  structurally valid under the table format. Structural parsing remains separate
-  from selected-use compatibility validation; never flatten an ambiguous path
-  into a different field binding.
-
-- **Direct format upgrades (confirmed 2026-09-24):** allow explicit v1-to-v3,
-  applying both intermediate version rules internally. The pinned official
-  [TableMetadata.Builder](https://github.com/apache/iceberg/blob/apache-iceberg-1.11.0/core/src/main/java/org/apache/iceberg/TableMetadata.java)
-  `upgradeFormatVersion` rejects downgrades and unsupported targets but does not
-  reject skipped versions. The evaluator expands the request into adjacent
-  internal steps; transition checking consumes that expanded trace. This does
-  not relax downgrade, unsupported-version or semantic-preservation checks.
-
-## Dependencies
-
-- Depends on routed Chunk-KV compare-exchange and scans, chunk streaming and range
-  reads, stable request identities, Group-0 service discovery, and `crowdb-rpc`.
-- The Apache Iceberg REST OpenAPI and table specification in
-  `doc/design/access-server/iceberge/` are normative. Apache Java, `iceberg-rust`, official
-  clients, and the REST Compatibility Kit are test oracles, not production
-  authorities.
-- R178 through R185 depend on this requirement. A material decision change must
-  first update R177 and the affected acceptance contracts.
-- General S3 requirements do not gate Iceberg correctness. Shared chunk and
-  transport improvements may be reused only below the protocol-authority boundary.
-
-## Acceptance
-
-- Given the eight child requirements, when their scopes and dependencies are
-  inspected, assert every core Catalog, Namespace, Table, commit, FileIO,
-  reclamation, REST, and cache concern has exactly one owner and R185 is not on the
-  correctness path. Invariant: ICE-I2 one authority. Integration test.
-- Given every declared v1, v2, and v3 capability and upgrade, when metadata and
-  files are compared with the backed-up table spec and reference implementations,
-  assert mandatory semantics are preserved and unknown or disabled optional
-  features fail before mutation. Invariant: ICE-I8 spec honesty. Integration test.
-- Given any supported or unsupported REST endpoint, when `/v1/config` and an
-  operation are compared with the backed-up OpenAPI, assert advertised behavior is
-  implemented and unadvertised behavior fails without mutation. Invariant: ICE-I8
-  spec honesty. E2E test.
-- Given rename, commit, clear, response loss, and crash injection, when another
-  Access Server resumes the operation, assert stable identities, one selected
-  generation, retry digest equality, and the clear boundary remain true.
-  Invariants: ICE-I1, ICE-I3, ICE-I6, and ICE-I7. Integration test.
-- Given metadata from bytes to hundreds of MiB and data files to TiB scale, when
-  load, commit, range read, and GC execute, assert no KV value, request allocation,
-  stream window, page, or background batch grows with the complete table or file.
-  Invariant: ICE-I5 bounded work. Integration test.
-- Given the canonical S3-shaped location and a general S3 object with a similar
-  textual key, when each is accessed, assert only the Iceberg authority can publish,
-  overwrite, authorize deletion, or reclaim the Iceberg file. Invariants: ICE-I4
-  and ICE-I9. E2E test.
-
-Required gates:
-
-- `pixi run -- cargo test -p crowdb-access-iceberg --all-targets`
-- `pixi run -- cargo test -p crowdb-access-server --all-targets`
-- `pixi run -- cargo fmt --all -- --check`
-- `pixi run rs-lint`
-
-## Open Questions
-
-- **Shared-chunk deletion range contract (confirmed 2026-09-26):**
-  `DeleteChunkRange.chunk_offset/chunk_size` remain two independent u32 fields,
-  both measured in bytes. No KiB conversion, alignment requirement, rounding or
-  u64 widening is needed. The API receives exact object ranges; physical shared
-  reclamation remains deferred and unsupported responses retain durable work.
-
-OI-1 separates functional/performance acceptance; OI-2 defers engine testing to
-the user's later independent project;
-OI-3 uses the existing disk/chunk allocation capacity boundary, with remaining
-GC and exhaustion-recovery requirements recorded in R183.
-
-- **OI-4 — Partition-statistics historical fields (confirmed):**
-  the backed-up specification's Partition Statistics File section describes a
-  union of all historical partition fields. Pinned Java 1.11.0
-  [Partitioning.partitionType / allActiveFieldIds](https://github.com/apache/iceberg/blob/apache-iceberg-1.11.0/core/src/main/java/org/apache/iceberg/Partitioning.java)
-  instead filters out fields whose source columns are absent from the current
-  schema. The user confirmed compatibility with this SDK projection: accept
-  this explicit omission case while validating retained
-  fields, types, row ordering and counts; do not silently treat omitted partition
-  values as known or broaden omissions to arbitrary fields. Statistics publication
-  now validates canonical rows and selected manifest counts; accepted immutable
-  references retain their writer semantics across evolution. This decision is resolved.
-
-- **OI-5 — Ordinary delete-rewrite equivalence responsibility (confirmed):**
-  distinguish valid file/metadata structure from proving that a rewrite preserves
-  the logical set of live rows. Java 1.11.0
-  [RewriteFiles](https://github.com/apache/iceberg/blob/apache-iceberg-1.11.0/api/src/main/java/org/apache/iceberg/RewriteFiles.java)
-  requires the caller's replacement data/delete records to preserve logical
-  equivalence. Its
-  [REST CatalogHandlers.commit](https://github.com/apache/iceberg/blob/apache-iceberg-1.11.0/core/src/main/java/org/apache/iceberg/rest/CatalogHandlers.java)
-  validates requirements, applies metadata updates and delegates publication;
-  that handler does not scan rows to prove equivalence.
-  - User decision: keep this computation the writer/engine's responsibility,
-    preserving CROWDB's implemented authorization, immutable-file authority,
-    schema/sequence/partition validation, position bounds, DV merge checks and
-    atomic publication. Add explicit compatibility tests and document that
-    ordinary equality/position-delete rewrites are not a server-side row-set
-    equivalence proof. This is not permission to bypass existing checks.
-  - Do not implement server-side row-set equivalence evaluation or make it a
-    catalog completion prerequisite. This assigns responsibility; it does not
-    assert that every engine independently recomputes and verifies its output.
-    Filename retention, matching counts or rejecting every removed delete are
-    not substitutes for equivalence and must not restrict legal compaction.
-  - This decision does not change the confirmed partition-statistics omission,
-    GC, ORC or engine-test deferrals. No human decision remains pending here.
-
-Unfinished implementation and unexecuted acceptance remain in the working plans.
-R179–R182 are closed by their acceptance gates, not by these decisions.
-R183 is complete; R184 REST conformance and R189 client/engine workflows remain open.
-
-- **OI-6 — Legacy zero format capability bits (resolved):** existing catalog
-  authorities persist zero even though installed table routes currently accept
-  v1/v2/v3 operations. Startup, REST, FileIO and credential refresh reject any
-  nonzero bits; config therefore advertises false while table operations work.
-  R184 must establish a durable version policy before changing these checks.
-  The operator explicitly activates a validated supported profile with an
-  authenticated, CAS-backed management operation. Zero remains literal and is
-  never silently widened on startup. The operation preserves catalog identity,
-  activation epoch, names, bounds, tables and prior retry records, and advances
-  only configuration generation. A pre-activation config request must not
-  advertise unsupported values as an operational profile; existing table data
-  remains intact while the operator rolls out activation. Clear creates a new
-  zero-profile catalog and therefore requires explicit activation again.
-
-- **OI-7 — REST retry-slot collision (resolved):** a prior native Java run
-  returned 503 when `TableWrites::admit` received `CatalogError::Busy`; that
-  observation did not establish whether the request carried a client key or
-  whether the Busy was a slot collision. The user selected stable fast-hash
-  primary slots with exact-identity durable overflow keys in `crowdb-common`;
-  C++ RPC remains unchanged. No old SHA-256 slot compatibility is required.
-  Deliberate library and real HTTP UUIDv7 collisions now admit and independently
-  replay both operations. The unmodified three-case Apache Java 1.11.0 native
-  FileIO suite passed twice consecutively under Pixi JDK 21. These results
-  resolve the collision policy, not the unproven cause of the earlier 503 or
-  all possible storage stalls. A new failure requires its own trace. R183 owns
-  physical reclamation of expired slot and overflow records.
-
-- **OI-8/OI-9 — Live GC scope (confirmed):** never interrupt reads or hold a
-  live table in `Reclaiming` for reclamation. R183 may leak unreachable files in
-  a Ready table. It physically reclaims only after table purge or catalog
-  retirement makes the entire authority inactive. A file selected by a pending
-  or future commit is therefore never sealed or deleted by a live pass. Existing
-  live tasks are retired without further deletion and any owned head fence is
-  released. No candidate-sealing or optimistic reproof protocol is required.

-### R184: access server / Iceberg — REST integration and core conformance
-
-## Problem
-
-Component repositories can be locally correct while the public catalog remains
-incompatible: `/v1/config` may advertise unimplemented routes, identifiers may be
-decoded differently between handlers, error types may not match the OpenAPI,
-authentication may disclose renamed resources, and an official Iceberg client
-may exercise a different sequence from unit tests.
-
-R178 through R183 define the native authority and operations. This requirement
-owns the single public REST composition, capability discovery, common protocol
-behavior, and conformance evidence for the first usable milestone.
-
-## Solution
-
-- **REST-I1 — Honest discovery:** `/v1/config` advertises exactly the enabled and
-  verified endpoint and format capability set.
-- **REST-I2 — One protocol boundary:** all handlers share bounded decoding,
-  authentication, authorization, request identity, error serialization, admission,
-  deadlines, cancellation, and metrics.
-- **REST-I3 — Standard semantics:** declared behavior matches the backed-up OpenAPI
-  and v1/v2/v3 table spec rather than one client implementation's quirks.
-- **REST-I4 — Failure isolation:** invalid, unauthorized, oversized, timed-out, or
-  cancelled requests do not leave an ambiguous mutation.
-- **REST-I5 — Interoperability:** official clients can create, evolve, write, commit,
-  load, time-travel, read, rename, expire, and drop core tables through CROWDB.
-
-1. Complete `app/crowdb-access-server/src/iceberg/` routing and
-   `lib/crowdb-access-iceberg/src/rest/`. Use one generated-or-verified wire schema
-   model tied to the backed-up OpenAPI; domain repositories never parse raw HTTP.
-2. Advertise config, namespace CRUD/properties/exists, table list/create/load/update/
-   drop/exists/rename, credentials, and metrics only when their requirements and
-   runtime dependencies are enabled. Do not advertise register-table, views,
-   transactions, or scan planning.
-3. Extend R178's common identity/authentication boundary and R179's namespace
-   decoding and pagination contracts to the complete surface. Implement decoding
-   for prefix, multipart namespace, table identifier,
-   pagination, idempotency key, data-access, snapshot-loading-mode, ETag, warehouse,
-   and purge parameters. Enforce header, URI, query, JSON, and response bounds
-   before allocating domain work.
-4. Apply configured bearer/OAuth authentication before namespace or table lookup and
-   authorize each catalog, namespace, table, management, credential, and file
-   action separately. Only advertise the token endpoint if token issuance is
-   configured and implemented. Error details never disclose a destination rename,
-   location, credential, or existence to an unauthorized principal.
-5. Map domain outcomes to the exact standard status and Iceberg error type. Preserve
-   conflict categories needed for client retry; never turn unknown updates,
-   unsupported operations, corruption, or expired authority into success.
-6. Add a conformance harness that runs the Apache REST Compatibility Kit and
-   official Java and Rust clients against one and multiple Access Servers with
-   fault injection. Treat the backed-up specs as authority when test oracles
-   disagree. R189 owns compute-engine and dataframe workflows.
-7. Publish an executable v1/v2/v3 capability matrix. Cover create/read/write and
-   v1-to-v2/v2-to-v3 upgrades with version-specific fixtures, including row-level
-   deletes, row lineage, deletion vectors, defaults, types, statistics, and format
-   encodings required by the declared profile.
-8. Add protocol metrics for endpoint, outcome class, latency, admitted bytes,
-   response bytes, retry/conflict class, and selected format version without logging
-   credentials, payloads, or unbounded identifiers.
-
-## Dependencies
-
-- Depends on R177 through R183. R184 is the integration gate for the core
-  correctness milestone.
-- R177 also permits an earlier foreground functional checkpoint before R183.
-  Build on completed namespace acceptance and run REST/client integration with
-  R180 through R182; retain reclamation-dependent gates as pending and do not
-  close R184 at that checkpoint.
-- Reuses the Access Server HTTP runtime and authentication infrastructure but keeps
-  an independent listener, routes, admission budgets, metrics, and shutdown drain.
-- R185 is deliberately not a dependency. Conformance must pass with caches disabled.
-- Client/version combinations selected for release must be pinned in the test
-  environment; oracle updates do not silently change the specification contract.
-- R189 owns Spark, Flink, Trino, Python dataframe, local SQL and ingest
-  interoperability against the R187 container. Its later results are not a
-  prerequisite for closing this REST/official-SDK requirement.
-
-## Acceptance
-
-- Given every enabled and disabled endpoint combination, when `/v1/config` is
-  queried and each route is called, assert discovery lists exactly callable routes
-  and unadvertised routes return unsupported without mutation. Invariant: REST-I1.
-  E2E test.
-- Given malformed identifiers, separators, tokens, headers, JSON unions, oversized
-  bodies, deadlines, and cancellation at mutation crash points, when requests run,
-  assert common errors are stable and durable operations are absent or recoverable.
-  Invariants: REST-I2 and REST-I4. E2E test.
-- Given requests without page tokens, empty tokens, UUIDv7 retry keys, terminal
-  conflicts, response loss, and catalog clear, when official clients list and retry,
-  assert complete unpaginated success, bounded resource errors, advertised key
-  retention, and no replay of retired resources. Invariants: REST-I2 and REST-I3.
-  E2E test.
-- Given principals with catalog, namespace, table, file, management, and no access,
-  when all route classes and rename hints are exercised, assert only authorized
-  information and credentials are returned. Invariant: REST-I2. E2E test.
-- Given the Apache compatibility kit and official Java and Rust clients, when the
-  declared endpoint matrix runs against multiple servers with response loss, assert
-  standard successes, conflicts, retries, pagination, and errors pass. Invariants:
-  REST-I3 and REST-I5. E2E test.
-- Given v1, v2, and v3 fixture matrices and valid upgrades, when differential tests
-  run against reference implementations, assert metadata and visible rows agree;
-  any oracle disagreement is resolved against the backed-up spec and recorded in
-  the fixture. Invariant: REST-I3. Integration test.

 ## Completed summary
 
-- R179 namespace and R181 table lifecycle acceptance are closed, with independent
-  writer credentials, bounded listing, rename/drop fencing, durable replay and
-  native/official-client recovery evidence. Implementations: `442f26c7`,
-  `4bbc2226`.
-- R182 atomic commits are closed: `af4ae819`, cleanup `0fef46c0`. Native process
-  kills cover 182 before/after durable-write cases across create, stage, publish
-  and update; independent listeners preserve exact replay and one visible head.
-  Head-CAS loser, bounded admission, statistics evolution and official SDK
-  publication/restart pass. Ordinary rewrite row-set equivalence stays engine-owned.
-- R180 FileIO is closed: `0a848834`. Immutable streaming/range files, durable
-  multipart, delegated credentials and validated generation-local REFS projections
-  pass acceptance. Corrupt/partial projections fall back to canonical JSON;
-  ALL and commit admission still parse canonical metadata.
-- Native PUT/Complete process kills pass all 44 cases twice. Background recovery
-  settles credits without extra Complete requests. Native credential lifecycle,
-  official Java FileIO/selected data-delete/catalog fixtures and Chunk-KV restart
-  pass; this is not an all-service DiskIO restart or physical-GC claim.
-- Evidence-backed FileIO fixes align bounded copy windows, avoid competing active
-  recovery, duplicate JSON scans and repeated directory reads, and overlap one
-  frame of copy I/O. The unchanged 5-MiB raw multipart fixture passes three runs;
-  no request timeout, caller retry, authority check or durability gate was relaxed.
-- Final gates: 616 library tests, 70 Iceberg-enabled server tests, default server
-  tests, 14 no-default transport tests, fmt, workspace lint and explicit
-  Iceberg-E2E clippy pass. Existing Maven warnings remain visible. Only the Pixi
-  toolchain was verified; locked LZ4 dependencies exceed the declared Rust 1.75
-  MSRV, so Rust 1.75 compatibility is not claimed.
-- ORC and broad engine/performance acceptance remain separately scoped below.
-  Physical GC has its own completed native acceptance and remains opt-in.
-  Unconfirmed diagnostic deadlines are retained as observations,
-  not claimed fixes or pending human design choices.
-
-## Remaining tasks in dependency order
-
-R179–R183 are complete. Continue foreground R184; R186 stays deferred.
-
-Execution detail and difficulty: [R184 REST conformance plan](plan-iceberg-rest-conformance.md).
-R184 route discovery, common admission and bounded metrics are implemented;
-explicit capability activation is selected and implemented. Foreground R184
-client/REST gates pass; engine and reclamation-dependent closure remains open.
-
-Pixi already pins OpenJDK 21 and Maven in the `iceberg-e2e` environment. The
-`test-java-iceberg-fileio-e2e` task now runs all three official Java native
-cases serially; two consecutive complete runs passed. A real HTTP UUIDv7
-collision test also confirms independent admission and replay. This resolves
-the fixed-slot collision policy, not every historical storage deadline.
-
-- [ ] **Release conformance — R184**: official Rust 0.10.0 namespace/table
-  lifecycle and lost-create-response recovery pass across two listeners; the
-  native variant also passes after Chunk-KV/listener restart. Apache RCK 1.11.0
-  isolated namespace, basic-create, rename, drop, missing-drop and list tests
-  pass; Java 1.11.0 RESTCatalog also reports a lost create response while a
-  second listener sees the committed table. The full
-  kit requires unsupported register/view cleanup and assumes external locations/
-  files outside native selected-file authority. An official Rust client also
-  rejects stale reads after clear/reactivation in the two-listener memory fixture.
-  The official Java SDK does not automatically retry mutation POST after a lost
-  response; direct HTTP fixtures cover same-key server replay. Native retirement
-  grace and two consecutive native Java FileIO suites pass. R189 owns engine
-  acceptance; physical GC has separate native acceptance under R183.
-  Files: conformance environments, SDK fixtures and capability tests.
-- [ ] **Requirement closure**: compare each requirement's acceptance cases with
-  executable evidence; update affected permanent architecture only as needed.
-  Remove each completed requirement/index entry and its plan together.
-  R189 separately owns container client/engine workflows; do not claim its
-  acceptance from this REST/official-SDK evidence.
-  - `file_scale_test` now verifies fixed range-read windows and serialized GC
-    cursors across a logical TiB address space using repeated immutable block
-    references; this is a traversal/bounds test, not a physical TiB benchmark.
-    Metadata selections of 256 MiB and 1 TiB fail the configured 64-MiB hard
-    limit before block I/O. Both focused test targets passed on 2026-09-27.
+The core milestone is complete. Native fault/restart acceptance, official Java
+1.11.0 and Rust 0.10.0 clients, the six supported Apache RCK cases, route/version
+admission, actual Parquet rows/deletes, upgrade/expiry/restart, and bounded logical
+TiB traversal have executable evidence. The permanent design records the matrix
+and exclusions. Full RCK, ORC and compute-engine certification are not claimed.
+
+Closure gates on 2026-09-27 passed: complete Iceberg library suite, default and
+Iceberg-E2E server all-targets (with the pinned Python environment), workspace
+fmt/lint and Iceberg-E2E clippy. The expanded native Java catalog case passed
+with v1/v2/v3 actual row reads and restart. A discovered post-drop FileIO pin
+regression is fixed, with GC proof/fence/worker coverage. No timeout or retry
+assertion was relaxed.
 
 ## Next — R189 container client/engine project
 
 - [ ] **Client and engine interoperability — R189**: after R187 is
   publish-ready, test Python dataframe, local SQL, Spark, Flink and Trino
   workflows in the separate container project. Pin versions and profiles there;
-  do not start broad engine tests during R184 closure.
+  do not infer engine certification from the completed SDK acceptance.
 - Preserve the acceptance scope: create/evolve/write/commit/load, time travel,
   row-level deletes, rename/expire/drop, cross-engine results and server restarts.
   Reuse existing SDK/native evidence, but do not treat it as engine certification.
 - Keep R189 client/engine acceptance pending until that project supplies
   executable results. Its environment and commands are specified when built.
 
-## Human decisions
-
-Only [R177 Open Questions](../backlog/R177-access-iceberg-catalog-foundation.md#open-questions)
-is authoritative. OI-6 is resolved as explicit management activation; no human
-decision remains for the currently executable REST work.
-
-OI-1 is resolved: functionality and performance are separate acceptance tracks.
-OI-2 is deferred by agreement to the user's later testing project, listed in Next.
-OI-3 is resolved: provisioned disk capacity and chunk allocation failure provide
-the capacity boundary, including configured limits for file-backed simulated
-disks. R183 completed GC/full-capacity recovery acceptance;
-no separate Iceberg quota or pre-full stop threshold is required.
-Fix evidence-backed obvious performance bugs; record architectural optimization
-work below for a consolidated backlog after functional implementation. Never
-trade away durability, fencing, bounds or assertions for a passing timing result.
+## Decisions and remaining ownership
+
+The completed catalog contract and confirmed compatibility decisions live in
+[Native Iceberg Storage](../design/access-server/iceberge/design-crowdb-iceberg.md).
+No human decision remains for REST/official-SDK correctness. R189 owns the
+separate engine project; R186 owns selected ORC, and R185 owns optional caches.
+Provisioned disk capacity remains the allocation boundary. Functional acceptance
+is separate from latency targets; preserve the observations below.
 
 ## Performance work to consolidate later

-# Iceberg REST Conformance Plan
-
-Upstream: [R184](../backlog/R184-access-iceberg-rest-conformance.md).
-Program: [functional catalog plan](plan-iceberg-functional-catalog.md).
-
-Goal: finish REST implementation and official-client evidence; R189 owns the
-separate container client/engine workflows.
-
-## Scope and starting point
-
-- Tasks 1–5 are implemented and verified for the declared foreground profile.
-  R179–R183 supply the storage, mutation and reclamation foundation; the R177
-  OI-6 activation decision is implemented. R189 tracks separate engine work.
-- Do not run Spark/Flink/Trino, physical GC or broad performance experiments.
-  Do not update the user guide. Human decisions belong in R177, not this plan.
-- Use the backed-up OpenAPI and table spec under
-  `doc/design/access-server/iceberge/` before selecting behavior. Java fixtures
-  pin Iceberg 1.11.0; the Rust client pins 0.10.0, and the RCK pins the Apache
-  1.11.0 source revision. The supported foreground subset has executable proof.
-
-## Findings from the initial code inspection
-
-- `wire/config.rs` builds all format overrides from `Capabilities::default()`;
-  these are false even when table routes are installed.
-- Initial code persisted zero capability bits, rejected every nonzero profile
-  at listener/REST/FileIO/credential boundaries and nevertheless accepted
-  table routes. R177 OI-6 selects explicit, authenticated activation rather
-  than silently treating zero as unrestricted or migrating at startup.
-- `http.rs` separately assembles endpoint strings and dispatches by broad path
-  prefixes. Table builders can be installed without namespaces, but dispatch
-  rejects every non-config route in that combination: discovery can overstate
-  callable routes. Test and fix this before changing format persistence.
-- Table mutation dispatch accepts POST/DELETE before parsing the complete target;
-  inspect unsupported subpaths before retry-ledger admission. Do not equate a
-  rejected request with proof that no recovery/ledger record was written.
-- No common REST protocol metrics are wired. S3 has an existing bounded atomic
-  metrics pattern, but must not become the Iceberg metric authority.
-- The OpenAPI access-delegation header is an optional list; the server may choose
-  any or none of the offered mechanisms. Prefix is optional. Do not require every
-  client to send the header or invent support for arbitrary nonempty prefixes.
-
-## Tasks in execution order
-
-- [~] **Closure audit**: map every REST acceptance case to executable tests,
-  refresh the library and server gates, preserve the pinned capability and SDK
-  evidence in permanent architecture, then remove the completed requirement and
-  this plan. Keep engine certification in the separate container project.
-  Files: Iceberg architecture, requirement/index, this plan.
-  - Added official Java generic-row reads for v1/v2/v3, both upgrade edges,
-    historical snapshots, logical expiry/reload, and equality-delete visibility.
-    Native acceptance is running; these new rows are not yet certified.
-  - First native attempt stopped before the SDK in two cases: shared setup
-    now creates `analytics`, but callers repeated that POST and got 409.
-    Removed the duplicate caller setup; shared setup still asserts HTTP 200.
-    The standalone FileIO case passed. Actual generic-row reads required the
-    pinned SDK's ORC runtime module even for Parquet; this adds no selected ORC
-    capability.
-  - The expanded catalog run exposed a production read regression after logical
-    drop: `ReaderPins::acquire` rejected Tombstone as Invalid(Record), returning
-    S3 500 for an already authorized HEAD. File reads can now persist a bounded
-    Tombstone pin and recheck the head; Reclaiming still rejects reads and
-    non-Ready tables still reject writes. GC proof/fence/worker suites pass.
-    The native catalog fixture now passes actual v1/v2/v3 rows, upgrade/expiry
-    and restart, with unchanged deadlines and no extra client retry.
-  - One selected-file upload returned an untraced storage 500 in an earlier
-    diagnostic. The isolated selected-file case and subsequent full-suite case
-    both passed. This observation is not claimed fixed by the drop-read change.
-
-- [x] **1. Unified route discovery — medium**: introduce a bounded endpoint
-  descriptor/classifier used by both config discovery and dispatch admission.
-  Keep identifiers encoded until the owning decoder validates them. Do not
-  duplicate an independent route list for metrics later.
-  Files: server `iceberg/http.rs`, new `iceberg/routes.rs`, library
-  `wire/config.rs`, new server `tests/iceberg_route_test.rs`.
-  - Enumerate foundation, namespace, table-read, table-write and credentials
-    combinations, including builder combinations unavailable in production.
-  - Match method and complete path before body reads or retry-ledger mutation;
-    preserve authentication precedence and standard HEAD response bodies.
-  - Verify register, views, transactions, scan planning, token issuance and
-    unsupported methods/subpaths are absent from discovery and cannot mutate.
-  - Check advertised templates against the backed-up OpenAPI, including the
-    optional-prefix convention. Do not add config/token/reporting routes to the
-    advertised set merely because their names appear elsewhere in the spec.
-  - Exit: real HTTP calls agree with discovery, disabled calls preserve authority
-    and ledger bytes, and existing Java discovery/list/load fixtures still pass.
-
-- [x] **2. Common protocol and authorization boundaries — medium**: add a
-  table-driven conformance matrix and repair only demonstrated differences.
-  Files: server `iceberg/http.rs`, `namespace_read.rs`, `namespace_request.rs`,
-  `table_read.rs`, `table_write/request.rs`, `table_write/lifecycle.rs`,
-  `table_credentials.rs`; existing namespace/table/credential HTTP tests.
-  - Cover malformed percent escapes/UTF-8, multipart namespaces, duplicate query
-    parameters and sensitive headers, warehouse, snapshots, ETags and purge.
-    Separate fields that OpenAPI permits ignoring from malformed known fields.
-  - Inspect pinned SDK behavior for absent/list-valued access-delegation headers
-    and credential refresh before changing FileIO configuration responses.
-  - Cover all four bearer roles plus invalid/missing credentials for every route
-    class. Preserve the independent writer role; do not introduce tenant ACLs or
-    OAuth issuance as incidental changes. Reject ambiguous authentication inputs.
-  - Assert no destination/name/location/credential disclosure on rejected calls.
-    Reuse clear, rename, staged-owner and expired-grant fixtures rather than
-    rebuilding the catalog state machine.
-  - Check bounded headers/URI/JSON/response admission and cancellation outcomes;
-    reuse existing durable crash evidence where production paths are unchanged.
-  - Exit: stable status/error types and exact authority/ledger behavior at each
-    rejected boundary, with no widened timeout or client retry policy.
-
-- [x] **3. Persisted format capability reconciliation — high**: establish one
-  effective profile from durable authority, supported implementation and installed
-  services, then use it consistently for discovery and admission.
-  Files: library `catalog/capability.rs`, `catalog/state.rs`,
-  `catalog/repository.rs`, `record/authority.rs`, `wire/config.rs`; server
-  `iceberg/runtime.rs`, `http.rs`, `file_http.rs`, `table_credentials.rs` and
-  table read/write admission; catalog/wire/HTTP/recovery tests.
-  - First trace initialize, clear, rename, restart and retired-context behavior.
-    Specify what legacy zero bits mean and how activation becomes durable before
-    coding migration. Do not reinterpret zero as unrestricted support, silently
-    rewrite stored authority at startup, or clear user data to enable features.
-  - Preserve persisted request/delegation bounds and configuration generations.
-    If migration requires a new operator choice, record concrete alternatives in
-    R177 and continue independent tasks; do not guess the policy.
-  - Test parse/read/create/write separately for v1/v2/v3 and each upgrade edge,
-    including confirmed direct v1-to-v3 intermediate validation. Audit selected
-    and retained versions rather than checking only the incoming JSON number.
-  - Define disabled-version behavior for load, mutations and upgrades; preserve
-    deterministic replay and maintenance fencing. Native byte storage is not
-    selected-format validation and must not infer FileKind from a Parquet PUT.
-  - Test legacy/new profiles, partial valid profiles, unsupported bits, listener
-    dependencies, restart and clear across REST/FileIO/credential refresh.
-  - Exit: config does not understate or overstate actual version admission, and
-    old catalogs cannot silently acquire broader persisted capabilities.
-
-- [x] **4. Bounded protocol observability — medium, cancellation edge medium-high**:
-  add lock-free counters and bounded latency measurements using fixed labels.
-  Files: new library `metrics.rs` and tests; server `iceberg/http.rs`, `body.rs`,
-  request-body readers, table retry/outcome paths and runtime status integration.
-  - Define endpoint/outcome, retry/conflict and selected version enums. Never use
-    namespace, table, raw URL, principal, token or payload as a metric label.
-  - Distinguish dispatch latency from response-body completion; count actual
-    admitted/request-consumed and emitted body bytes, not Content-Length alone.
-    Handle HEAD, empty bodies, streamed errors, timeout, cancellation and Drop
-    without double counting or keeping permits alive.
-  - Reuse the repository's status/export conventions; do not expose an unauthenticated
-    diagnostics route on the catalog listener by default.
-  - Apache client report-metrics POST is a separate protocol operation from
-    server observability. Keep it unadvertised until bounded schema validation,
-    authorization and meaningful handling are implemented; do not return fake
-    success solely to satisfy a client fixture.
-  - Exit: deterministic unit/body tests prove counts and cleanup; endpoint labels
-    remain bounded even under arbitrary paths and error input.
-
-- [x] **5. Official-client and compatibility evidence — medium-high**: extend
-  existing Java/native fixtures, add a pinned official Rust client harness and
-  investigate the Apache REST Compatibility Kit's actual runner/artifacts.
-  Files: server `tests/common/iceberg_java/`, new Rust/kit fixtures under tests,
-  `tests/iceberg_table_sdk_test.rs`, `tests/iceberg_file_http_test.rs`,
-  dedicated Pixi test environment and dependency manifests only as needed.
-  - First run config/namespace/create/load/commit against one listener, then two
-    listeners with response loss and retired-context retry. Reuse native storage.
-  - Build an executable matrix of version, endpoint, selected format, SDK version,
-    fixture and result. Include upgrades, defaults, lineage, deletes/DV, statistics,
-    snapshot refs/time travel, rename/drop and logical snapshot expiry.
-  - Reuse existing verified cases; add missing cases rather than rerunning every
-    historical process-kill scenario after a documentation-only matrix change.
-  - Report upstream-client feature gaps and exact kit omissions explicitly. Do
-    not patch clients, waive errors, or count a custom fixture as the Apache kit.
-  - Exit: REST and official-client rows have executable evidence; R189 owns
-    engine rows, and full R184 closure still requires its evidence audit.
-
-## Verification
-
-Current verified foreground evidence:
-
-- The retry ledger now uses only fast-hash primary slots and exact-identity
-  overflow keys; no previous SHA-256 slot lookup remains. The complete Iceberg
-  library suite, four namespace-write HTTP tests, workspace formatting and
-  lint, and Iceberg-E2E server Clippy pass after the cleanup. The three-case
-  official Java native suite passed twice serially with Pixi OpenJDK 21.
-- Complete route classification and config discovery share one descriptor set.
-  Real HTTP tests cover four installation combinations, absent routes, unchanged
-  store records, authentication order and ambiguous duplicate Authorization.
-- Existing namespace/table/lifecycle/credential/admission suites pass with the
-  shared route gate; a pinned OpenAPI access-delegation list preserves table load.
-- Initial protocol metrics count fixed route/outcome classes, actual consumed
-  request bytes, emitted response bytes, dispatch and body lifetime, retry
-  classification and selected load version. Real HTTP tests cover create, HEAD,
-  unsupported requests, timeout/cancellation classification and v3 load. A
-  manager-only diagnostic endpoint exports the snapshot even when catalog reads
-  stall, without adding an Iceberg REST capability. File body error and drop
-  tests retain bounded streaming and cancellation behavior.
-- R177 OI-6 selects explicit management activation. The implementation adds
-  authenticated `activate UUIDv7 NAME EPOCH CAPABILITY_BITS_HEX` with durable
-  CAS/retry/audit, monotonic bits, unchanged catalog ID/epoch/name/bounds and
-  incremented config generation. Zero-profile config returns 503; table routes
-  reject without mutating while namespace operations remain available. Discovery
-  filters installed routes by the durable profile. Selected-version read,
-  conditional load, HEAD, create, update, lifecycle and credential refresh use
-  the same profile; direct v1-to-v3 upgrade requires both intermediate edges.
-  FileIO grants intersect role and selected read/write/create support rather
-  than infer format from a Parquet PUT. Library and real HTTP tests cover
-  partial profiles, expansion, replay after response loss, direct upgrade and
-  clear reset.
-- Apache Iceberg Rust 0.10.0 official REST client compiles in a separate pinned
-  Cargo fixture and passes namespace and table create/list/load/rename/drop against the
-  live CROWDB HTTP service through two independent listeners sharing one test
-  store. Its dependency lockfile is retained; its injected memory storage
-  factory is not evidence for S3 data I/O.
-- The official Apache Iceberg 1.11.0 RCK is pinned to tag commit
-  `6976e020b894f6a6777704df2b8c4458cb291ae9`. It runs from an external
-  source checkout with a native CROWDB stack. The initial Gradle bootstrap found
-  an inherited invalid `JAVA_HOME`; the fixture now selects the Pixi Java home.
-  The initial full catalog suite ran with its default assumption that namespaces
-  need not be created: 106 tests, 83 failures, 12 skipped, largely at missing
-  namespace admission. The supported `rck.requires-namespace-create=true`
-  setting corrects that harness assumption; its isolated `testBasicCreateTable`
-  and `testCreateNamespace` both pass against native CROWDB. Isolated
-  `testRenameTable`, `testDropTable`, `testDropMissingTable` and `testListTables`
-  also pass. A full configured
-  diagnostic exposed tests that assume
-  register-table/views, direct filesystem metadata paths, or externally supplied
-  data files without CROWDB's selected-file authorization. Unsupported view
-  cleanup then leaves shared test namespaces in place and causes cascading
-  duplicate-namespace and bounded-operation failures. That diagnostic was
-  terminated after the independent failure classes were identified; no full-kit
-  pass is claimed. The pinned harness defaults to six passing supported tests
-  and accepts `CROWDB_ICEBERG_RCK_SELECTOR` for isolated diagnostics. Isolated
-  `testLoadTable` fails at create with HTTP 400: upstream `CatalogTests` calls
-  `withLocation(baseTableLocation(TBL))`, which supplies a `file:/tmp/...` path, while
-  CROWDB requires its reserved native table location. This is not fixed by
-  accepting an unservable path or weakening native FileIO authority.
-- The RCK harness now selects its six supported catalog cases in one Gradle
-  invocation by default. Its JUnit report confirms six tests, zero failures,
-  zero errors and zero skips: create namespace, basic table create, rename,
-  drop, missing-drop and list. `CROWDB_ICEBERG_RCK_SELECTOR` still permits an
-  exact comma-separated diagnostic subset. This is supported-surface evidence,
-  not a claim that the full catalog suite passes.
-- Upstream Java 1.11.0 `RESTSessionCatalog` supplies a fresh UUIDv7
-  `Idempotency-Key` for mutations when config advertises a lifetime, but its
-  `ExponentialHttpRequestRetryStrategy` retries I/O failures only for idempotent
-  HTTP methods, not POST. Rust 0.10.0's `RestCatalog::create_table` builds a POST
-  without a generated idempotency header. Consequently the official SDK
-  create-response-loss fixtures verify an error plus durable visibility rather
-  than inventing automatic same-key mutation retry; that server contract remains
-  covered by direct HTTP fault tests.
-
-Executable foreground evidence matrix (not engine certification):
-
-- **All versions / namespace REST / Rust 0.10.0, Java 1.11.0 and RCK 1.11.0:**
-  `iceberg_rust_sdk_test`, `iceberg_namespace_sdk_test` and the RCK harness.
-  Namespace create/list/load/rename/drop and pagination pass; no data format is
-  selected by these calls.
-- **v1/v2/v3 / table metadata REST / Java 1.11.0:**
-  `iceberg_table_sdk_test`, `table_create_sdk_test`,
-  `commit_evaluator_sdk_test` and `table_metadata_sdk_snapshot_test` pass.
-  These rows select canonical metadata JSON, not data-file reads.
-- **Native selected Parquet and S3 FileIO / Java 1.11.0:**
-  all three `iceberg_file_http_test::official_java_` cases pass serially under
-  Pixi JDK 21, including catalog/Parquet publication, selected data/delete use
-  and restart; this does not establish an ORC or engine row scan.
-- **Fault and retirement / Rust 0.10.0 and Java 1.11.0:**
-  `iceberg_rust_sdk_test`, `iceberg_rust_retired_sdk_test` and
-  `iceberg_java_response_loss_test` pass two-listener response-loss and
-  clear/reactivation checks. The Rust native response-loss case also passes
-  after Chunk-KV and listener restart. SDKs do not automatically replay a
-  lost mutation POST with the same key; direct HTTP tests cover that contract.
-- **Not certified:** the full configured RCK suite needs register/views or
-  external file locations outside the declared native authority; Spark/Flink/
-  Trino results and ORC remain separate pending work. R183 reclamation has
-  separate native acceptance and remains opt-in at runtime.
-
-- **Namespace, version-independent:** Rust 0.10.0 `iceberg_rust_sdk_test`
-  covers create/list/load/rename/drop through two listeners; Java 1.11.0
-  `iceberg_namespace_sdk_test` and Apache RCK 1.11.0 isolated
-  `testCreateNamespace` cover the official REST namespace surface. The Rust
-  command is below; the RCK selector is
-  `org.apache.iceberg.rest.RESTCompatibilityKitCatalogTests.testCreateNamespace`.
-- **Official-client response loss:** Rust 0.10.0
-  `iceberg_rust_sdk_test::official_rust_client_observes_lost_create_reply_on_another_listener`
-  discards the successful create response after publication. The official client
-  sees an error while another independent listener lists and loads the committed
-  table. The separate ignored
-  `official_rust_client_lost_reply_survives_native_storage_restart` repeats the
-  scenario with two real Access Server processes, then restarts Chunk-KV and both
-  listeners before the official client loads and removes the retained table.
-  Neither case claims automatic SDK retry after the lost response.
-  Java 1.11.0 `iceberg_java_response_loss_test` independently verifies that
-  `RESTCatalog` reports the lost POST response while another listener loads and
-  drops the one committed table. Its proxy accepts ordinary client connection
-  closes but rejects an upstream create response other than HTTP 200.
-- **Retired context:** Rust 0.10.0
-  `iceberg_rust_retired_sdk_test::official_rust_client_rejects_retired_catalog_after_clear`
-  keeps two official client instances open across a durable clear and explicit
-  reactivation. The old table becomes unreadable, while the same clients can
-  create and load a new table with the same name in the replacement catalog.
-  This two-listener case uses the in-memory store; it does not claim a native
-  15-minute delegated-access grace run or same-key SDK mutation retry.
-- **v1, table create/update/load:** Java 1.11.0
-  `iceberg_table_sdk_test::official_catalog_creates_commits_upgrades_stages_and_refreshes_native_credentials`
-  creates v1 and commits schema/properties over REST. The same-version creation
-  and update metadata are compared structurally with Java fixtures by
-  `pixi run cargo test -p crowdb-access-iceberg --test table_create_sdk_test`
-  and `pixi run cargo test -p crowdb-access-iceberg --test commit_evaluator_sdk_test`.
-  All pass. The in-memory Java run alone does not prove data-file visibility.
-- **v2, table create/update/load:** the same library commands exercise v2
-  fixture rows. Rust 0.10.0 `iceberg_rust_sdk_test` creates its default v2
-  table on one listener, then lists/loads/renames it across both; Apache RCK 1.11.0
-  isolated `testBasicCreateTable`, `testRenameTable`, `testDropTable`,
-  `testDropMissingTable` and
-  `testListTables` pass against native storage. All pass.
-- **v3 and upgrades:** the same library commands exercise v3 fixture rows;
-  `pixi run cargo test -p crowdb-access-iceberg --test table_metadata_sdk_snapshot_test`
-  checks v1/v2/v3 refs and v3 row lineage. Java 1.11.0's table SDK fixture
-  requests direct v1-to-v3 upgrade over REST, and
-  `pixi run cargo test -p crowdb-access-server --test iceberg_table_http_test`
-  verifies selected v3 load metrics. All pass. These are metadata and REST
-  checks, not an end-to-end v3 row scan.
-- **Deletes and auxiliary files, selected formats:**
-  `pixi run cargo test -p crowdb-access-iceberg --test parquet_position_delete_test`,
-  `--test commit_retained_statistics_test`,
-  `--test partition_statistics_rows_test` and
-  `--test snapshot_manifest_reader_test` pass with pinned format fixtures.
-  Selected-file validation is not a Spark/Flink/Trino read.
-- **Durable retry/restart:** existing server native `iceberg_commit_sdk_test`,
-  `iceberg_file_http_test` and R180–R182 fault suites cover response loss and
-  recovery. `iceberg_full_stack_test::namespace_functional_crud_survives_native_storage_and_listener_restart`
-  passes pinned PyIceberg namespace CRUD against two listeners before and after
-  a Chunk-KV restart. The native Rust response-loss fixture above covers a
-  successful create response lost at the HTTP boundary; the in-memory retired
-  fixture covers stale official-client reads but not same-key mutation retry.
-- **Outside the declared foreground profile:** the full configured RCK catalog
-  suite exercises register/views and foreign file locations; official SDKs do
-  not issue automatic same-key retries for lost mutation POST responses.
-  Engine row-level visibility remains pending; R183 native reclamation acceptance
-  is complete and remains separate from this foreground profile.

-Native Java FileIO diagnostic on 2026-09-25: the three-test serial suite passed
-two cases, but the catalog/Parquet case returned HTTP 503 during partition
-statistics publication. The corresponding native chunk-stream log showed an
-append stuck in `append_durability` and `WriteStalled`; a second serial run
-failed earlier during catalog initialization with `Store(Client(Deadline))`.
-After the service binaries were rebuilt, the exact catalog/Parquet case passed
-alone twice, including restart verification; two serial suites still failed at
-different table operations while another serial suite passed all three cases.
-Temporary stage instrumentation localized one new 503 to `TableWrites::admit`
-returning `CatalogError::Busy` from the REST retry ledger before mutation. The
-earlier journal stall and this retry-admission failure are separate observations.
-The retry-slot collision policy now uses exact-identity overflow after a
-fast-hash primary slot. Deliberate library and real HTTP UUIDv7 collisions
-admit and replay independently. The unmodified three-case Java native suite
-passed twice consecutively under Pixi JDK 21; `test-java-iceberg-fileio-e2e`
-now runs all three serially. The earlier Busy remains unattributed to a
-specific request header or collision. The temporary instrumentation was
-removed; do not weaken fixtures or widen timeouts if the failure recurs.
-
-The native official Rust retired-catalog full-grace case also reaches
-`Store(Client(Deadline))` after about 20 minutes; Chunk-KV reports a partition
-already in `WriteStalled`, but the old logs omit the first stream error. The
-uncommitted diagnostic work records journal append and idle renewal failures.
-The first instrumented recurrence showed a journal `WriteStalled` at the clear
-write and a failed ChunkDB cursor advance, without a disk-capacity error. The
-underlying idle writer had a 30-second lease, while Chunk Stream scheduled
-renewal every 12 minutes; ChunkDB's same-cursor advance also returned without
-persisting the renewed lease. Production now schedules renewal within one
-third of the configured lease and persists the same-cursor renewal. The
-first rerun still failed because the test launched a prebuilt Chunk-KV server
-binary from before those fixes. After explicitly rebuilding ChunkDB and
-Chunk-KV, the isolated native Rust full-grace test passed in 1242.99 seconds.
-This covers retired-catalog reads and clear/reactivation over refreshed native
-storage, not the full RCK suite or physical reclamation.
-Chunk Stream now retries confirmed-absent appends by repeated rollover and
-resolves cursor/manifest uncertainty against durable state. Small write and
-production Chunk Stream share the mirror-strip write and replacement flow;
-the stream worker retains the active strip image, including its acknowledged
-prefix, and replacement resolves uncertain publication against chunk metadata
-before another attempt. Focused small-write, stream, production-adapter and
-partition tests pass. Chunk-KV now names the drained handoff state
-`TransferQuiesced`; any journal append error, including a malformed position
-count, instead moves that partition to `Recovering`. A focused injected journal
-failure test confirms no later write or handoff checkpoint can treat it as a
-healthy transfer source. The transfer worker and partition suites pass.
-
-Pinned client commands:
-
-- Native harnesses launch prebuilt service executables; run
-  `pixi run cargo build -p crowdb-chunkdb -p crowdb-chunk-kv-server`
-  after changing those services or their dependencies, before running a native
-  test. `cargo test -p crowdb-access-server` alone does not rebuild them.
-- Rust 0.10.0: `pixi run cargo test -p crowdb-access-server --features
-  iceberg-e2e --test iceberg_rust_sdk_test -- --ignored --nocapture`.
-- Apache RCK 1.11.0: clone tag `apache-iceberg-1.11.0` outside the workspace,
-  set `CROWDB_ICEBERG_RCK_ROOT` to its root, clean an isolated
-  `CROWDB_RUNTIME_ROOT`, then run `pixi run cargo test -p
-  crowdb-access-server --features iceberg-e2e --test iceberg_rck_test --
-  --ignored --nocapture --test-threads=1`. The test executes the unmodified
-  upstream Gradle task for six supported catalog cases and injects
-  `rck.local=false` and `rck.requires-namespace-create=true`.
-
-- Unit: capability bit/profile tests, wire/config/parameter tests, bounded metrics
-  counters and body lifecycle. Place all Rust tests under each crate's `tests/`.
-- Integration: real HTTP route/role combinations, durable rejection, legacy
-  authority and context changes, admission and cancellation. Reuse existing
-  `tests/common/iceberg_store.rs` and native fixtures.
-- E2E: pinned Java, Rust and Apache kit; one native stack at a time. Set the same
-  isolated `CROWDB_RUNTIME_ROOT` for `pixi run clean-env` and the test command.
-  Preserve unrelated persistent state. Never clean a running stack.
-- Start with changed test targets, then
-  `pixi run cargo test -p crowdb-access-iceberg --all-targets`
-  and default/Iceberg server all-targets.
-  Keep the no-default Iceberg transport gate when touching the common boundary.
-- Gates: `pixi run cargo fmt --all -- --check`, `pixi run rs-lint`, and
-  `pixi run cargo clippy -p crowdb-access-server --features iceberg-e2e --all-targets -- -D warnings`.
-- Java and native commands/environment are in the functional plan's verification
-  section. Rust/kit commands must be recorded after the actual harness is pinned.
-- No new runtime locks or unsafe exceptions. Investigate timing failures instead
-  of weakening assertions, widening deadlines or adding test-side retries.
-
-Foreground gate on 2026-09-25: workspace Rust format and lint, Iceberg-E2E
-Clippy, complete Chunk-KV and Iceberg library suites, default, Iceberg-enabled
-and no-default Iceberg Access Server suites, the six-case Apache RCK subset,
-official Rust two-listener and native restart cases, Java response-loss and
-four table SDK cases, and all three native Java FileIO cases pass. One Rust
-native test invocation without an isolated runtime root hit the test harness's
-paired-port assertion after the RCK run; the same test passed under the plan's
-isolated runtime root.
-
-## Completion boundaries
-
-- Main implementation checkpoint: tasks 1–4 and their targeted acceptance.
-- Foreground interoperability checkpoint: task 5, excluding explicitly deferred
-  engine and reclamation gates.
-- Full R184 closure: audit its REST/official-SDK acceptance against executable
-  evidence, update affected architecture, and remove the requirement and this
-  plan together. R183 evidence is complete. R189 client/engine acceptance is
-  independent and cannot be claimed from the R184 SDK results.

+# Single-node container development
+
+For running CROWDB, see the [Docker user guide](../../doc/user-manual/docker-single-node-user-guide.md).
+This page describes building from source on a Linux amd64 development or CI host.
+
+```sh
+pixi run build-single-node-container
+pixi run test-single-node-container
+```
+
+- Compilation runs on the host with the locked repository dependencies. Cargo
+  and CMake reuse existing build outputs; npm uses its local download cache.
+- The build stages release programs, their required shared libraries, UI and
+  deployment files under `target/container-runtime`. Existing runtime data and
+  credentials are never part of the Docker context.
+- Docker only packages these files into the pinned Ubuntu runtime image. It
+  does not install Pixi or compilers, compile source, or use a custom base image.
+- Packaging checks dynamic linkage inside Ubuntu and verifies the staged
+  revision/version against image metadata. A different host ABI must pass these
+  checks and the container tests before its artifacts can be used.
+- The default local image is `crowdb-iceberg-single-node:dev`. Set
+  `CROWDB_CONTAINER_IMAGE` to build and test a separate candidate tag.
+
+`pixi run stage-single-node-container` produces the runtime directory without
+building a Docker image. The release workflow archives the verified directory
+and packages those same files in its publish job, without recompiling them.
+Docker Hub publication is manual; actual publication verification is deferred
+until administrator preparation is complete.

They must build the workspace, discover -an internal process order, provision topology and storage metadata, initialize -credentials and an Iceberg catalog, and keep several processes alive. This -blocks the development, demonstration, CI, and client-interoperability use cases -defined by the source Docker release brief provided for this requirement. - -The existing full-stack harness proves many components together, but its -in-process setup and temporary paths are not a distributable runtime contract. -The [user guide](../user-manual/user-guide.md) describes manual service -operation, while the [ChunkDB root design](../design/chunkdb/design-crowdb-chunkdb.md) -permits an explicit `unsafe_colocated` minimum topology without promising disk, -node, or zone fault tolerance. Packaging ad hoc test behavior would create a -second storage semantic, hide partial startup, expose internal ports, or lose -state on restart. The preview instead needs a bounded, reproducible composition -of the normal binaries with an honest non-production boundary. - -`crowdb-web` also has an unresolved authority split: its older bare-metal -configuration mixes cluster topology and launch policy. The Docker image must -not copy or replay that file. Its monitor owns container processes, while -Group 0 owns CROWDB system topology and service registration. The wider -CLI/bare-metal configuration and authority cleanup is tracked separately by -[R188](R188-console-group0-authority.md), not required to verify this local image. - -Concrete scenarios are a developer uploading and range-reading Parquet through -S3, a PyIceberg client using the enabled REST catalog and FileIO operations, an -operator viewing the same instance in the web console, and a CI job restarting -the container against the same volume before repeating those operations. - -## Solution - -The first image is a single-host preview for disposable development and -integration data. It is not a production, high-availability, upgrade-stable, or -fault-tolerant deployment. - -- **DOCKER-I1 — One-command service:** one documented container invocation - starts one usable CROWDB instance and publishes Iceberg REST/FileIO on host - port 80. The container also listens for independent S3 on 81 and Web on - 8080; S3 publication is optional and the unfinished GUI is not published - by user-guide examples. These overrides do not change bare-metal defaults. -- **DOCKER-I2 — Product-path fidelity:** the image runs the normal - `crowdb-kv-server`, `crowdb-diskdb`, `crowdb-diskio`, `crowdb-chunkdb`, - `crowdb-chunk-kv-server`, `crowdb-access-server`, `crowdb-iceberg`, and - `crowdb-web` binaries. Docker-only code may compose and bootstrap them but may - not replace their protocol or persistence semantics. -- **DOCKER-I3 — One durable boundary:** all durable database files, topology, - bootstrap state, credentials, and bounded rotating logs live below the single - `/opt/crowdb/data` mounted data root. The image declares this path as a Docker - volume, so an omitted mount creates an anonymous volume for a disposable - trial; startup recommends an explicit named volume for data to retain across - container recreation. Executables and packaged UI/config - templates are immutable image content; generated runtime configs, sockets, - status, and process IDs live below `/opt/crowdb/run` and are disposable. The - monitor records important bootstrap, readiness, child lifecycle, probe - failure, restart, drain, and exhaustion changes in its own bounded - `log/monitor/` files; ordinary logs contain no secrets. -- **DOCKER-I4 — Dependency-gated readiness:** container readiness becomes true - only after durable bootstrap is complete and KV, disk, chunk, S3, Iceberg, and - web probes all confirm the same instance is usable. A live PID is not proof of - readiness. -- **DOCKER-I5 — Monitored recovery:** a dedicated `crowdb-monitor` daemon is PID - 1 and the sole owner of every child process. It detects unexpected exits and - failed bounded liveness probes, drops readiness before recovery, terminates and - reaps the old process, and restarts the failed process plus affected dependents - in dependency order with the same durable identity and configuration. Restart - attempts use bounded backoff and a finite crash-loop budget; exhaustion - terminates the - container nonzero so the container runtime's restart policy can recreate it. - `SIGTERM` disables restart, stops external admission first, drains bounded - work, stops dependent services in reverse order, and leaves restartable - durable state. -- **DOCKER-I6 — Secret boundary:** the image contains no baked-in credentials or - fixed production secrets. Secret values never appear in image layers, command - arguments, health output, or ordinary logs. -- **DOCKER-I7 — Honest preview:** startup output, UI, examples, labels, and - release metadata identify this as a single-node non-production preview and - advertise only capabilities proven by its pinned acceptance matrix. -- **DOCKER-I8 — Runtime-only initialization:** the image contains no initialized - disk, topology, group, tenant, catalog, or bootstrap manifest. On an empty data - root, `crowdb-monitor` creates Group 0, Group 1, and the remaining topology at - runtime. On a complete existing data root it performs validation only and - never reissues creation. An interrupted initialization resumes with the same - durable identities; unknown or conflicting existing state fails without - mutation. -- **DOCKER-I9 — Convenient authenticated access:** on first boot the monitor - generates strong S3 and Iceberg credentials, stores them only in the mounted - secret directory with mode 0600, and exposes client credentials through an - explicit local retrieval command. Startup logs print the retrieval command and - public endpoints but never credential values. -- **DOCKER-I10 — Honest multi-disk simulation:** the preview provisions one node, - one disk group, and four 16 GiB sparse file-backed disks with one zone each. - Each registered disk has its own stable identity and backing file so DiskDB and - DiskIO exercise a normal multi-disk topology. All files remain on one host - filesystem and are not presented as replica or independent failure-domain - durability. -- **DOCKER-I11 — Container authority boundary:** Group 0 is the sole durable - authority for CROWDB cluster topology and service registration after the - monitor creates it. The monitor's durable manifest contains bootstrap - identity and progress, not an independent topology authority; an interrupted - bootstrap resumes only after proving the same Group 0 state. Docker Web uses - configured Group 0 seeds and service registration for cluster information, - and monitor status for PID, restart, and health information. It never loads, - writes, or restores a local console topology or `registry.toml`; Group 0 - does not manage Docker image, volume, process, or launch information. -- **DOCKER-I12 — Verifiable preview publication:** only a manually triggered - workflow targeting a Git release tag may publish the gated `linux/amd64` - image to `crowdb/crowdb-iceberg`, after protected-environment approval. - Creating or pushing a tag alone never publishes. Version and `git-` - tags are immutable; moving `preview` and `latest` tags are not published. Every public digest - has a verifiable signature, SBOM, and build provenance. Pull-request workflows - build and test but have no publication authority. -- **DOCKER-I13 — Deployment-profile boundary:** container implementation lives - under the repository-root `container/` directory. `crowdb-monitor` provides a - topology-neutral process graph, supervision, probe, rendering, and bootstrap - runtime; the named **CROWDB Single-Node Container** profile supplies this - requirement's two groups, four file disks, services, ports, and paths. A future - multi-node image or bare-metal launcher can reuse the monitor without adding - single-node policy branches to its supervision core. - -```text -crowdb-monitor (PID 1) -> start / probe / restart every process - host clients -> S3 access server -----------+ - -> Iceberg REST/FileIO --------+-> Chunk-KV -> ChunkDB -> DiskDB/DiskIO - -> web console ----------------+ | - +-> one KV server - +-> Group 0: system - +-> Group 1: data -``` - -The source layout for this deployment is: - -```text -container/ - crowdb-monitor/ reusable deployment runtime crate and binary - single-node-container/ CROWDB Single-Node Container profile - Dockerfile amd64 runtime-only image - templates/ profile-owned service configuration inputs - tests/ profile and container acceptance assets -``` - -Only the current profile is created by R187.

Docker - Web reads those records and live registrations through the existing Group 0 - client path. An unavailable Group 0 fails cluster queries closed; no local - topology or process snapshot substitutes for system metadata. Wider - CLI/bare-metal convergence is R188. -- **`crowdb-web.toml`:** is a versioned, non-secret process configuration. It - contains the web bind address and port, Group 0 management seeds, packaged UI - root, monitor status endpoint, log policy, and request bounds. It contains - no topology, process PID, binary path, inline credential, or SSH material. - In this image `crowdb-monitor` renders it at - `/opt/crowdb/run/config/crowdb-web.toml` on every start and invokes - `crowdb-web --config` with that path. -- **Runtime/UI state:** the monitor alone owns Docker child PIDs, restart - generation, probes, and crash-loop state.

The monitor sets `CROWDB_RUNTIME_ROOT=/opt/crowdb/run` and -passes explicit data and log paths to every child. - -1. Build release artifacts on the existing Linux amd64 host with the - repository's locked Rust, C++, and UI dependencies, reusing incremental - compilation. Docker only packages the prepared runtime files; it does not - install Pixi or compilers, run source compilation, or require a custom base - image. The first preview publishes no arm64 image or multi-architecture - manifest. Install the `crowdb-web` static UI under - `/opt/crowdb/ui`; the web service must resolve that packaged runtime - path rather than a build-workspace path. The build must not execute database - initialization or copy any generated disk, topology, Group 0, Group 1, tenant, - catalog, credential, or bootstrap-manifest state into an image layer. The - runtime image is based on a digest-pinned `ubuntu:24.04`, contains only - required runtime libraries and artifacts, runs as a dedicated non-root user, - and records the source revision and preview version in OCI labels. Build - context excludes local runtime data, credentials, test output, VCS data, and - unrelated build products. Reject incompatible host binaries during image - linkage checks and acceptance. The release job consumes the exact staged - runtime files from its successful verification job instead of recompiling. -2. Add a dedicated `crowdb-monitor` deployment daemon as the image entrypoint - and PID 1. It owns configuration validation, runtime initialization, child - creation and reaping, process and functional-liveness monitoring, restart - backoff and budgets, readiness aggregation, signal handling, and shutdown. It - classifies the durable root before mutation, validates every path, address, - capacity, and secret input before starting storage, and never interprets S3 - or Iceberg requests. A replacement child may start only after the prior PID is - reaped and its listeners are no longer serving; the daemon never permits - overlapping owners of one durable identity. -3. Drive the minimum topology through existing management and client APIs only - at runtime. For an empty data root, `crowdb-monitor` durably records a - versioned `Initializing` manifest with generated stable identities, starts the - minimum dependencies needed for management calls, and creates one rack, one - node, one disk group, four stable disk identities backed by the 16 GiB sparse - files `/opt/crowdb/data/disks/disk-0001.img` through `disk-0004.img`, one - DiskDB instance, one `unsafe_colocated` ChunkDB placement domain, one Chunk-KV - service, one S3 tenant, one active Iceberg catalog, and one KV server with - exactly two groups. - Group 0 is the system group and owns topology, service, and other system - authority; Group 1 is the data group and owns user data routed by the preview. - Each step is replay-safe and advances the manifest until it is durably - `Ready`. If startup finds `Initializing`, the monitor resumes with the same - identities and operation inputs. If startup finds `Ready`, it makes no create - call: it starts services against existing state and validates both group - identities, roles, bindings, tenant, catalog, and disk before readiness. A - non-empty root with a missing, corrupt, unsupported, or conflicting manifest - fails without creating, replacing, or truncating anything. -4. Start dependencies in probe order: the KV server with ready Group 0 and Group - 1, DiskDB and DiskIO, ChunkDB, Chunk-KV, S3 and Iceberg access processes, then - `crowdb-web`. Each stage has a bounded deadline and emits a diagnostic naming - the failed component. Partial startup never reports ready. On crash or failed - liveness, `crowdb-monitor` first marks the instance unready, stops affected - dependents, restarts the failed layer, revalidates its durable authority, and - then restarts dependents in this same order. Internal management, RPC, and - health listeners bind only to the container network namespace and are not - declared as public image ports. -5. Configure `crowdb-access-server` with normal S3 authentication on - `0.0.0.0:81`, `crowdb-iceberg` with its independent authenticated catalog - and native FileIO listener on `0.0.0.0:80`, and `crowdb-web` on - `0.0.0.0:8080`. The quick start maps only Iceberg port 80 and uses - `http://localhost`. Optional S3 publication maps port 81; the unfinished - GUI is not published. `CROWDB_ICEBERG_PUBLIC_URI` defaults to the local - Iceberg URI and is the one documented override when a remote hostname, - reverse proxy, or different host-port mapping changes the client-visible - address. S3 buckets and credentials do not select or authorize Iceberg - resources. -6. Make authentication automatic but explicit. On a fresh volume, - `crowdb-monitor` generates the S3 master key, one preview S3 access-key pair, - and four distinct Iceberg read/write/manage/clear bearer tokens required by - the existing services. It writes all server-only material to - `/opt/crowdb/data/secrets/server.env` and writes only client endpoints, region, - S3 access key/secret, and the Iceberg writer token to - `/opt/crowdb/data/secrets/client.env`; both files are owned by the container - user with mode 0600 and are reused unchanged after restart. The local command - `crowdb-monitor credentials show --format env` prints `client.env` only when - explicitly invoked, so the quick start can use - `docker exec crowdb crowdb-monitor credentials show --format env` while normal - startup logs reveal only that command. Authentication is necessary because S3 - requires SigV4 credentials and the Iceberg server requires distinct bearer - roles; automatic generation removes that setup burden without disabling either - protocol boundary. -7. Run Docker Web from the monitor-rendered `crowdb-web.toml` without a local - console registry or topology restore. Its cluster read model uses Group 0 - and live registration; its process read model uses monitor status. It rejects - hardware and process mutations and requires the management bearer for - logical writes. The web UI identifies each source and shows unavailable - state rather than a fabricated local fallback. CLI/bare-metal configuration - migration and cross-mode tests belong to R188. -8. Enforce the mounted data-root contract and subtree ownership shown above. - The image declares `/opt/crowdb/data` as a volume so a run without an - explicit mount uses Docker's anonymous volume; startup explains how to use - a named volume instead. Empty-root detection cannot treat - a non-empty directory as fresh merely because its manifest is absent. Reject - missing-on-non-empty, corrupt, unsupported, or state-conflicting bootstrap - manifests and on-disk layout versions without mutation. The four disk - identities, backing paths, one-zone layouts, and 16 GiB per-disk capacities - are fixed in the first bootstrap manifest; adding, removing, replacing, or - resizing a disk is unsupported in this preview. This preview does not promise - in-place upgrade compatibility until a later requirement defines it. -9. Add container-level liveness and readiness commands. Container liveness - proves `crowdb-monitor` is responsive and its event loop is advancing without - contacting external networks. The monitor separately runs bounded functional - liveness probes for every child rather than treating a PID as healthy. - Readiness checks the web `/healthz`, KV leadership and topology, storage - registration, S3 health, Iceberg `/v1/config`, completion of bootstrap, and - absence of an active restart. Probes use internal least-privilege credentials, - bounded timeouts, per-process failure thresholds, and disclose no secrets. -10. Add a hermetic Docker acceptance harness and pixi tasks for image build and - test. It starts from an empty named volume, waits for readiness, runs AWS CLI - and boto3 object PUT/LIST/HEAD/range-GET/GET against a Parquet fixture, runs - the pinned PyIceberg operations currently enabled by R184, checks the web UI - and API, restarts the container with the same volume, and repeats reads and - catalog loads. It also tests first-start runtime initialization, interruption - and replay after every initialization step, restart with a `Ready` manifest - without creation calls, invalid configuration, unavailable dependency, every - required-process crash and liveness hang, successful monitored restart, - crash-loop budget exhaustion, monitor failure, `SIGTERM`, wrong secrets, - read-only/unwritable volume, and missing, corrupt, incompatible, or conflicting - bootstrap manifest outcomes. -11. Publish `doc/user-manual/docker-single-node-user-guide.md` as the Docker - quick start. Its minimal Docker command pins a version tag, names the - container `crowdb-iceberg`, and maps only port 80. Common options and an - extended example explain a named volume at `/opt/crowdb/data`, optional S3, - runtime restart policy, shutdown allowance and log rotation. It retrieves - generated preview credentials with the explicit monitor command, and includes - independent S3 and Iceberg examples. The compatibility list names exact - tested client versions and operations; pure Parquet-over-S3 results are not - presented as Iceberg conformance. -12. Add separate CI build/test and release workflows. Pull requests build the - amd64 image and run all Docker gates without registry write credentials. A - operator manually triggers the release workflow against a Git release tag; - it reruns the complete gates for the exact commit, waits for protected- - environment approval, then publishes to `crowdb/crowdb-iceberg` under an - immutable release-version tag and immutable `git-` tag. The workflow never emits `latest`, refuses to overwrite either - immutable tag, and attaches a signature, SBOM, and build provenance to the - published digest. arm64 publication is deferred until a later requirement - supplies a Linux arm64 toolchain and the complete Docker E2E matrix. -13. Keep reusable deployment mechanics in the `container/crowdb-monitor` crate - and every single-node decision in `container/single-node-container`. The - monitor consumes a validated profile to construct its dependency graph, - render configs, bootstrap authorities, and aggregate health; it does not - infer topology from its executable name or Docker environment. Unit tests - exercise the runtime with synthetic profiles, while Docker acceptance uses - only the named single-node profile. Do not create placeholder multi-node or - bare-metal implementations in R187. - -## Dependencies - -- Depends on the delivered S3 baseline R152 through R166 and its restart-safe - object path. R167 multipart upload, R168 shared-object reclamation, R169 shared - chunk-tree GC, and R170 RDMA are not required for the initial image and must - not be implied by its capability claims. -- Depends on R177's native Iceberg authority and the implemented R178 through - R183 functionality.

Log: `/tmp/crowdb-r187-final-container.log`. -- Release native acceptance passes upload, storage restart, GC and credential - cases, but the crash matrix returns HTTP 500 while preparing multipart case - `true-17-false` before fault injection. Diagnosis is ongoing; the suite is - not accepted. Java/Rust/RCK acceptance runs separately while investigating. -- The test harness's two runtime-namespace tests now have an explicit - `test-harness` Pixi task in `test-unit`; both pass. CI coverage includes all - 25 workspace packages without a support-package exception. -- Native crash replay exposed an RPC connection startup race: the worker was - registered before its frame handler and live-connection entry. A first - request could be consumed without dispatch or receive a rejected response, - surfacing as a 5-second Chunk-KV client deadline or an Iceberg HTTP 500. - Install callbacks and register the connection before exposing it to the - worker. The focused C++ first-frame test and all 71 RPC tests pass; complete - native and final container acceptance is being rerun. -- Java SDK acceptance passes all ten tests. The Rust SDK fixture lockfile had - version `0.1.0` while its manifest is `0.1.0-dev`; `--locked` refused to run, - and the test timed out waiting for the fixture handshake. Refresh the - fixture lockfile, build the pinned fixture before Rust SDK tests, and run its - binary through Pixi to keep compilation outside the handshake clock. RCK - passes its pinned Apache compatibility selectors; the complete Rust SDK - rerun passes five cases, including the full durable retirement grace. -- Final native suite passes nine cases in 1024.67 seconds, including all - file/table publication crash boundaries, credentials, GC and storage restart. - Java passes ten cases, Rust five, RCK one, and access-server 85. Rust fmt, - clippy, C++ format, RPC 71 tests, tree lint, CI coverage, version and release - policy checks pass. The last local image rebuild follows the final commit. -- New native suite diagnosis: multipart's 5 MiB part received/stored in 7.39 s, - then reread all staged blocks for Content-MD5, reaching 9.62 s before catalog - publication against a 10 s request budget. The suite failed twice with 503; - isolated runs passed near the deadline. Move MD5 to the decoded input stream, - checking it at successful EOF before publication. No timeout, durability or - assertion changes. Two new regressions failed before the change; all seven - file-encoding tests pass afterward. Full native and SDK acceptance is pending. -- Tooling gates: 25-package CI reachability, version consistency (`0.1.0-dev`), - shell syntax and both workflow actionlint checks pass. Public documentation - local links pass; the conduct policy needs no changes. -- Performance investigation is deferred at the user's request. The observed - debug/null-DiskIO upload timing is not an NVMe bandwidth measurement. Keep - current work scoped to correctness, acceptance and release preparation; do - not add a block-write pipeline optimization to this requirement. R190 now - tracks the full read/write/delete/GC review and refactor; the user explicitly - selected R187 completion first. -- Requested comparison only: release build, native DiskIO null stack, 5 MiB - JSON with Content-MD5; three ordinary PUTs took 2791/2682/2752 ms and three - UploadPart requests took 2091/2184/2159 ms (all HTTP 200). Timings include - HTTP response completion, exclude client signing and setup; UploadPart does - not include CompleteMultipartUpload. Temporary probe removed. Evidence: - `/tmp/crowdb-put-comparison-release.log`. Keep the original multipart size. -- MD5 fix committed as `b57409fc`; file encoding tests, native multipart upload, - native file recovery matrix, Rust fmt and clippy pass. Moved C++ link-isolation - probe and `pixi run tree-lint` both exit 0. -- Newly enabled credential lifecycle test duplicated the shared setup's - `analytics` namespace creation (409 instead of 200). Remove that redundant - setup call, preserving lifecycle assertions; verification is pending. -- Native storage restart test passed once, then returned - `Store(Client(Deadline))` while initializing multipart admission after its - second Chunk-KV restart. An isolated run with client diagnostics is in progress. -- Accepted local image from revision `481000f0`: - `crowdb-iceberg-single-node:v0.1.0-dev`, - `sha256:f93388a48fd85025330c71b35d5dc9020449c9e6de331d8391e970ea135fe573`, - 259,759,890 bytes. Image smoke and complete container E2E pass, including - all eight crash/hang recovery paths, Web outage/recovery, persisted restart, - budget exhaustion, lifecycle and secret-free logs, invalid identity, - manifest/profile rejection, anonymous volume and PID 1 death. Previous `dev` - tag remains intact. No Docker Hub publication occurred. -- Final Web integration passes. Console UI passes all 86 component and 56 - browser tests (4.6m). Full KV Server and monitor pass; Rust fmt/clippy pass. - Full S3/PyIceberg acceptance passed on the host packaging revision; the final - container E2E rechecks those clients against this exact runtime image. - -- Revision `c6badf31` builds and passes image smoke as - `crowdb-iceberg-single-node:verified-candidate`, image - `sha256:e8fb20a5c07b17f6bcb7dd57c84d1bae97d9c0b231f73a251b8ab00c2d162559`, - 259,713,194 bytes. Its full E2E stopped at the DiskIO crash event assertion: - recovery reached Ready, but an earlier `probe_failed` suppressed the later - `child_exited` event. Add the failure-order regression and fix event emission - before accepting this revision.

Emit the exit independently of the probe-failure count; - recovery still happens once. All eight supervisor tests and the full monitor - suite pass, along with Rust fmt/clippy. Rebuild and rerun container E2E with - this correction before marking fresh-image acceptance complete. - -- Host candidate complete container E2E passed: interrupted initialization, - first boot, authenticated clients/logical writes, all eight children under - KILL and STOP, recovered browser view, persisted-volume restart, restart - exhaustion, lifecycle/secret-free logs, durable identity rejection, corrupt - manifest/invalid profile rejection, anonymous volume and monitor death. -- Full S3 client acceptance passed (17 cases); full PyIceberg task passed, - including native storage/listener restart. Rust fmt/lint and release policy - checks passed for the packaging change. The five Console browser failures - are being resolved in the Console authority follow-up; R187 is not yet closed. - -- Host-compiled candidate image builds successfully and passes image smoke, - including container-only ports/capabilities and the Regex/ICU exclusion. - Size is 259,561,209 bytes versus 298,967,926 for the previous image, a - 39,406,717-byte reduction. Packaging identical staged files with a warm Docker - cache took 0.476 seconds; this excludes compilation and is not a cold-build - measurement. An incorrect source-revision build argument is rejected. -- Real-container browser acceptance passes: Group 0 outage clears topology - while monitor process state remains visible, then topology recovers. Full - container crash/hang/restart acceptance also passed on the host candidate. -- Workspace Rust fmt and lint pass after host packaging changes. Local release - policy checks pass; actual Docker Hub publication remains deferred. - -- The user superseded the isolated Docker compilation flow with host - incremental compilation followed by runtime-only Docker packaging. No custom - CROWDB base image is required. `patchelf` is now a locked Linux host packaging - tool, not a runtime dependency. -- Full Console UI run: 85 component tests pass; browser suite has 51 passing - and 5 failing tests. One failure reports missing live registration for a - pre-Group-0 nonmember node. These failures remain under diagnosis. - -- Full `pixi run test-console` completed with exit 0 before the nonmember - discovery fix. Its affected browser regressions now pass; updated complete - Console gates are tracked in the Console authority plan. -- Candidate image build attempt 1 failed during dependency download, before - compilation: compiler-rt package transfer ended with TLS unexpected EOF. - Attempt 2 uses a BuildKit rattler cache so completed package downloads survive - failed builds. No release workflow was triggered. -- Release policy and shell syntax checks pass with the retained manual job and - version/commit tags; moving `preview` and `latest` tags are rejected. -- Folly dependency audit: only `ConcurrentHashMap` is used by CROWDB RPC. The - locked shared Folly requires Boost.ProgramOptions, Context and Filesystem; - Filesystem also brings Container. These four packaged libraries total about - 0.84 MB. Removing them without rebuilding/replacing Folly breaks its loader - contract. The much larger Regex/ICU closure is already absent from local - DiskIO after the link fix; image smoke now explicitly rejects its return. - -- User-facing quick start uses only Docker, a version tag, container name - `crowdb-iceberg`, and the Iceberg port-80 mapping. S3 on 81 is optional; - the unfinished GUI on 8080 is not published by guide examples. Container - listener overrides do not change bare-metal defaults. Common options and - an extended persistent-volume example follow the minimal startup path. -- Monitor log regression gates pass: complete JSON events survive rotation, - five files per child log channel are retained across PID generations, and - unrelated files are preserved. Missing files during concurrent rotation are - tolerated; active child logs are not unlinked. Child stderr mirrors into - Docker logs under the existing profile policy. Focused monitor-log/process - tests, workspace fmt and lint passed on 2026-09-27. -- Docker Hub release workflow and local policy checks are retained. The user - deferred only actual publication verification until their preparation is done. -- Release preparation is confirmed for `crowdb/crowdb-iceberg:v0.1.0-dev`; - `VERSION` remains `0.1.0-dev`. Publication uses the GitHub `DockerHub` - environment and its user-configured reviewer approval. The extra - `PREVIEW_RELEASE_ENABLED` variable has been removed at the user's request. - `DOCKERHUB_USERNAME` remains an environment variable and `DOCKERHUB_TOKEN` - a secret. Release policy checks pass; no registry publication has run. -- Candidate builds and smoke/E2E scripts accept `CROWDB_CONTAINER_IMAGE` so the - existing dev tag can remain intact during final-image verification. -- Docker Markdown/HTML guide now records volume, ports, credentials, probes, - client boundaries, restart, logs and host core-collector limitations. Core - volume retention and source-line symbolization moved to R188 at the user's - request and are not R187 completion gates. - -- Checkpoint gates on 2026-09-27 passed: `pixi run rs-fmt-check`, - `pixi run rs-lint`, `pixi run test-monitor`, `pixi run test-console-shared`, - `pixi run tree-lint`, `pixi run test-rpc-ct` (71 tests), and - `pixi run test-diskio-ct` (128 tests). Tree lint exited zero with warnings - in unchanged C++ sources; no C++ source formatting changed.

Its source label predates this checkpoint commit; - final-image acceptance still requires a rebuild from the final revision. - -- Recovery authority acceptance passed on the rebuilt image: supervisor - readiness remains false after a child restart until the persisted manifest, - Group 0, storage, credentials, catalog, and Web authority are revalidated. - The container E2E covered all-child crash/hang recovery, persisted-volume - restart, monitor-death replay, crash-loop exhaustion, and rejection of a - changed durable credential identity. `pixi run rs-fmt-check`, - `pixi run rs-lint`, the focused supervisor test, image smoke, and the full - container E2E passed. -- The existing `crowdb-single-node-preview:dev` image passed release policy, - image smoke, full container E2E, S3/PyIceberg client operations, persisted - restart, all-child SIGKILL/SIGSTOP recovery, crash-loop exhaustion, and PID 1 - replay.
