Summary

First-party executable and copyable v2 Flows now carry explicit current CLI/model pairs instead of inheriting an adapter default that may not be authorized for the selected credential:

  • Claude: claude-sonnet-5
  • Codex: gpt-5.6-sol
  • Cursor: gpt-5.6-sol-high
  • Grok: grok-4.7

This updates Software Factory, PR review, Babysitter/reviewer, task graph, stuck-run triage, communication/drive flows, provider-selectable examples, and the close-PR dogfood flow. The generated drive-cloud-v2.yaml now copies and verifies the exact model from drive.yaml and refuses a missing model.

The runtime contract is unchanged: authored step > named agent > adapter default precedence and the exact (cli, model) readiness probe remain fail closed. This PR does not change the Claude adapter default.

Incident

This is Flows lane B for failed Cloud v2 run https://agentrelay.com/cloud/dashboard/workflow/b5d6ab22-caee-58c5-a1c7-4c02d4aa9e26/runner. The run reached agent-3 with an omitted model, inherited claude-opus-5, and the connected credential rejected that exact probe.

The incident generator fix landed separately in AgentWorkforce/agentrelay.com#121. This PR repairs the independently shipped Flows sources and prepares the authoritative source commit needed by the later release and Cloud catalog pin update.

Invariant

shipped-source-models.test.ts inventories current first-party TypeScript and declarative v2 source under examples, workflows, and SDK dogfood:

  • every inline agent requires both cli and model;
  • every literal pair must be in the current supported map;
  • current YAML steps require an effective CLI and explicit model;
  • named-agent and dynamic-pair exceptions are explicit, call-exact, count-exact waivers backed by focused tests;
  • generated dist, node_modules, and symlinks are excluded so ignored build products cannot alter the source inventory.

Changing the reviewed Software Factory bytes also updates the hosted capability-isolation digest and its regression fixture.

Corrective review closure

  • The scanner now resolves only immutable, symbol-scoped string constants; mutable aliases remain unresolved and require an exact waiver.
  • Every named-agent declaration must resolve both a literal CLI and model, and every omitted inline pair must map call-exactly to complete named declarations.
  • Dynamic waivers are bound to the exact source file, call identity, and count; regression fixtures prove mutable aliases and incomplete declarations fail.
  • Babysitter, legacy reviewer, and close-PR custom wrappers now require an explicit model; the four supported built-in CLIs retain their current exact pins.
  • Current aliases without verified frozen prices now pair nominal dollar budgets with enforceable token ceilings.
  • The composition test stubs its declared server preflight, so linux-x64-artifact no longer depends on api.github.com availability.
  • Corrective head: a87bfffebe7610953792f90af67105b59129c2bf.

Verification

  • PATH=<node-24.21.0>:<bun-1.4.0> RELAYFLOWD_BIN=<built-relayflowd> npm test in packages/sdk: 218 files passed, 1 skipped; 3513 tests passed, 3 skipped.
  • Focused inventory plus process-group flake rerun: 2 files, 11/11 passed.
  • npm run typecheck:regressions && npm test in packages/surface: generated helpers current; 10 files, 53/53 passed.
  • Babysitter: 53 passed, 7 intentional TODOs, then typecheck and build passed.
  • Research: 27/27 passed and typecheck passed.
  • python3 ops/gen-drive-cloud-v2.py --check: generated workflow current and equivalent.
  • git diff --check: passed.

RED/GREEN evidence: the first full SDK run caught the stale hosted Software Factory digest and the inventory following an ignored dangling symlink. After updating the digest and making traversal source-only, those regressions pass. Environment-only reds from an unset RELAYFLOWD_BIN, Bun 1.4.2, and Node 26 were eliminated by rerunning with the repository-compatible built daemon, Bun 1.4.0, and Node 24.21.0.

Production boundary proof

Fresh post-generator-fix run af723592-ea24-50c0-b7bb-8adaeb0c40a8 completed all 19 authored steps. Agents 3/6/8/10 ran with codex + gpt-5.6-sol; logs contain neither agent_cli_unresolved nor claude-opus-5. Its terminal control-plane status is failed only because the authored workflow deliberately parked needs_human after complete-19, not because of model resolution. The immutable original failed run was not retried or modified.

Rollout / rollback

After review and merge, a human must publish a Flows release before Cloud updates the recommended catalog immutable ref/digest/fixtures. Roll back by reverting this commit before release, or pinning Cloud to the prior artifact after release. No publish, Cloud mutation, merge, or deployment is performed by this PR.


Note

Medium Risk
Touches agent dispatch, budget composition, and preflight probing across many first-party flows and the SDK entrypoints; incorrect pins or probe timing could block runs, but changes align with existing fail-closed preflight rather than weakening auth or spend limits.

Overview
First-party flows, plugins, and dogfood paths now declare explicit cli + model pairs (current pins like claude-sonnet-5, gpt-5.6-sol) instead of relying on adapter defaults that can fail credential probes at runtime. Custom reviewer/repair wrappers must supply reviewerModel / input.model; built-in harnesses get generated defaults only when overrides are absent, not when blank.

Budgets move from shorthand strings to structured { tokens, dollars, wallclock }, with docs and examples using 100,000 tokens per nominal dollar when frozen prices are missing so enforcement stays on tokens. Flow-extension manifests and composition now understand token ceilings alongside dollars/wallclock.

Runtime/SDK: --probe-cli is served from both the ordinary flows CLI and the sealed authored Node entry so flows can fail closed on CLI/model readiness before GitHub or repo effects (Babysitter legacy reviewer, close-pr repair loop). gen-drive-cloud-v2.py inlines roster cli/model on every agent step. Hosted Software Factory digest and extensive shipped-source static analysis tests guard inline agent/LLM calls, declarative YAML, and budget literals.

Summary by cubic

Pins explicit CLI/model pairs across first-party executable, copyable v2, and active v1 Cloud flows so runs no longer inherit adapter defaults that can fail credential checks; invalid or ambiguous configurations now fail before agent work starts.

Model contract

  • Supported pairs (claude-sonnet-5, claude-opus-5, gpt-5.6-sol, gpt-5.6-sol-high, grok-4.7) are pinned across Software Factory, PR review, Babysitter/reviewer, task graph, stuck-run triage, communication/drive flows, provider examples, and the close-PR dogfood flow.
  • The shipped-source invariant (shipped-source-models.test.ts) audits TypeScript and YAML agent/llm calls, covering callable aliases, bound/indirect/nested/returned receivers, mutation and aggregate provenance, assignment/reflective and callable-member write targets, and flow-header binding.
  • Named-agent and budget declarations are accepted only from the inline flow header; invalid or ambiguous configurations fail closed.
  • Runtime precedence (authored step > named agent > adapter default) and pinned readiness probing are unchanged; the Claude adapter default is untouched.

Budgets and validation

  • Budgets use literal immutable dollar and token ceilings; unpriced aliases use 100,000 tokens per nominal dollar.
  • Custom Babysitter and close-PR CLI/model overrides are validated and probed through the sealed authored runtime before any repository or GitHub effects; blank overrides fail closed.
  • prospect-demo now requests and posts structured { message: string } output.
  • Generated drive-cloud-v2.yaml copies and verifies the exact model from drive.yaml.
  • Focused and full SDK gates pass (218 files / 1 skipped; 3516 tests / 3 skipped) with typechecks, generator equivalence, and git diff --check green.
  • Rollout: publish a Flows release after merge before Cloud updates its catalog reference; no Cloud mutation or deployment is performed by this PR.

  • The shipped-source invariant now scans both f.agent(...) and f.llm(...); a mutation fixture proves an LLM-only missing model and missing token ceiling fail the gate.
  • The close-PR dogfood flow validates a custom CLI/model pair immediately after input parsing, before any worktree or GitHub side effect; its regression proves no cd or gh command runs on invalid input.
  • Focused regression gate: 2 files, 37/37 tests passed.
  • Full SDK gate with Node 24.21.0, Bun 1.4.0, and the built RELAYFLOWD_BIN: 218 files passed / 1 skipped; 3514 tests passed / 3 skipped.

  • The shipped-source invariant inventories f.agent(...), f.llm(...), and tagged-template f.llm syntax. Tagged calls fail as unpinned; prospect-demo now uses the options form with claude / claude-sonnet-5 and an output string schema.
  • All user-supplied CLI/model entrypoints changed by this PR were audited. close-pr and current/legacy Babysitter validate normalized declaration syntax before filesystem, GitHub, or network effects; invalid custom values fail closed.
  • Focused final-state gate: 2 files, 38/38 tests passed.
  • Prospect-demo strict standalone typecheck with --skipLibCheck: passed.
  • Babysitter final state: 54 passed / 7 intentional TODOs; typecheck passed.
  • Full SDK final-state gate with Node 24.21.0, Bun 1.4.0, and the built RELAYFLOWD_BIN: 218 files passed / 1 skipped; 3515 tests passed / 3 skipped.

  • prospect-demo now asks for JSON matching its object output schema ({ message: string }) and posts result.message, so the pinned options-form f.llm call does not fail schema verification on a normal response.
  • Focused shipped-source/close-pr gate: 2 files, 38/38 tests passed.
  • Prospect-demo standalone strict typecheck with --skipLibCheck: passed.
  • Final serialized full SDK gate with Node 24.21.0, Bun 1.4.0, and the built RELAYFLOWD_BIN: 218 files passed / 1 skipped; 3515 tests passed / 3 skipped.
  • The normal parallel full gate reached 3514 passing tests and one unrelated transient worker-cli hidden .bun-build EACCES race; its isolated file passed 18/18 before the clean serialized full gate.
  • python3 ops/gen-drive-cloud-v2.py --check, git diff --check, and the live base guard passed; origin/main remains 66eb9a932239af0a4d2e318b64607010b1f6c474.

  • Legacy Babysitter now applies generated reviewer defaults only when CLI/model inputs are absent; explicitly blank or whitespace values fail syntax validation before repository, GitHub, network, or agent effects.
  • A body-level regression invokes the exported legacy flow with blank CLI and blank model cases and proves zero commands and zero agent dispatches.
  • Babysitter suite: 55 passed / 7 intentional TODOs; typecheck passed. Legacy reviewer suite: 50/50 passed.
  • Focused shipped-source/close-pr SDK gate: 2 files, 38/38 passed.

  • Declarative shipped-source inventory now validates both type: agent and type: llm steps through the same supported-pair gate; mutation fixtures prove missing and unsupported YAML LLM models fail.
  • TypeScript budget inventory now parses literal dollars and tokens, rejecting missing/nonliteral/negative values, zero-dollar budgets, and ceilings above 100,000 tokens per dollar. Mutation coverage rejects 20,000,000 / $2 and accepts the 200,000 / $2 boundary.
  • Focused invariant gate: 3/3 passed.
  • Final constrained full SDK corpus with Node 24.21.0, Bun 1.4.0, and the built RELAYFLOWD_BIN: 218 files passed / 1 skipped; 3515 tests passed / 3 skipped.
  • Earlier parallel full runs exposed unrelated process-group/hosted-snapshot flakes; the affected files passed isolated (9/9 and 27/27) before the clean constrained full run.
  • python3 ops/gen-drive-cloud-v2.py --check, git diff --check, and the exact live base/head guard passed; base remains 66eb9a932239af0a4d2e318b64607010b1f6c474.

  • The shipped declarative inventory now covers the actively launched v1 workflows/drive-cloud.yaml alongside current v2 sources, resolves roster-backed steps, and rejects incomplete roster pairs. Regeneration added exact models to all three v1 Cloud roster declarations.
  • Budget enforcement now resolves shorthand properties and identifier-backed object/numeric literals only through symbol-scoped const declarations; a factored 20,000,000-token / $2 budget regression is rejected.
  • Focused invariant gate: 1 file, 3/3 passed. Production and test TypeScript typechecks passed.
  • Full pinned Node 24.21.0 + Bun 1.4.0 + built RELAYFLOWD_BIN SDK gate: 218 files passed / 1 skipped; 3515 tests passed / 3 skipped; duration 135.19s.

  • Rejected mutable const budget aliases: identifier-backed budget objects are accepted only when their symbol is immutable and used solely as a direct budget header binding.
  • Property mutation/access, aliasing, calls, spreads, duplicate ceiling fields, mutable declarations, and nonliteral values now fail closed.

📝 Walkthrough

Walkthrough

Flows and workflows now specify model identifiers and token ceilings. Reviewer and repair flows validate CLI/model pairs and probe readiness. SDK changes add extension token-budget handling and TypeScript scanners that audit model declarations, invocation patterns, flow headers, and budgets.

Changes

Model declarations and validation

Layer / File(s) Summary
Babysitter reviewer model selection
examples/babysitter/*, examples/babysitter/legacy/*, examples/babysitter/tests/*, docs/SURFACE.md
Reviewer flows validate settings, select defaults for supported CLIs, require models for custom CLIs, and check readiness. Schemas, budgets, examples, and tests are updated.
Authored-runtime CLI/model probe
packages/sdk/src/authored-node-entry.ts, packages/sdk/src/authored-node-utility.ts, packages/sdk/src/cli.ts, packages/sdk/tests/*probe*, packages/sdk/tests/authored-node-runtime.test.ts
The authored Node entry point and CLI handle model-scoped probe arguments before normal startup or verb parsing. The utility calls the probe and returns its result.
Close-PR repair model selection
packages/sdk/scripts/dogfood/close-pr*, packages/sdk/tests/close-pr-flow.test.ts
The flow validates CLI/model values and checks readiness before repository or GitHub operations. It passes the resolved values to the repair agent.
Extension token-budget validation and composition
packages/sdk/src/flow-extension-*, packages/sdk/src/hosted-extension-manifest.ts, packages/sdk/src/cli/add-extension.ts, packages/sdk/tests/flow-extension-compose.test.ts, packages/sdk/tests/plugin-extension.test.ts, packages/sdk/tests/hosted-extension-protocol.test.ts
Extension manifests accept positive safe-integer token ceilings. The loader composes declared limits, rejects incompatible ceilings, and displays token budgets.
Static binding and invocation analysis
packages/sdk/tests/helpers/shipped-source-*
New TypeScript helpers trace binding provenance, static values, global members, writes, reflective calls, and flow and worker invocations.
Shipped model and budget audits
packages/sdk/tests/shipped-source-models.test.ts, packages/sdk/tests/shipped-source-worker-invocations.test.ts, packages/sdk/tests/shipped-source-model-provenance.test.ts, packages/sdk/tsconfig.tests.json
Tests audit TypeScript and declarative model pairs, named-agent pins, flow headers, worker calls, and token ceilings.
Flow models and token ceilings
docs/BUDGET.md, docs/SURFACE.md, examples/*, workflows/*
Flow and workflow declarations specify model identifiers. Several budgets add numeric token ceilings. Research declarations, tests, and budget documentation are updated.
Generated workflows and demo/runtime updates
ops/gen-drive-cloud-v2.py, examples/prospect-demo/demo.flow.ts, packages/sdk/src/hosted-extension-runtime.ts, packages/sdk/tests/babysitter-native-extension.test.ts
The workflow generator requires and verifies roster models. The demo posts a schema-constrained message field. The hosted extension digest and related test fixture change.

Priority: ⬆️ High

Estimated code review effort: 5 (Critical) | ~120 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to 49eed

The model pinning, readiness checks, and budget ceilings introduce no known blocking issues. One small follow-up remains: two new audit test files should be added to the test typecheck configuration so type errors in those files are caught.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 49eed

The changes make execution choices explicit and add limits without a demonstrated new privilege path. Deployment and downstream enforcement remain only partly verified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — Model pins affect provider selection for shipped flows, while token-budget declarations affect extension composition and the existing execution-budget handoff. No new cross-system authority edge is established by the inspected changes.

Trust Boundaries and Controls

  • observed — The changed repair flow fails its initial readiness check unless the resolved executable exists and reports authentication and model availability; its agent step also passes through SDK preflight before admission.

Resilience and Maintainability Implications

  • observed — The SDK preflight caches CLI probe outcomes during one authored execution. Repeated step checks therefore do not, by themselves, establish fresh credential status after a mid-run change; the inspected change did not introduce this cache.

Hardening Proposals

  • proposed — If mid-run credential revocation must stop later repair attempts, bound the lifetime of cached readiness results or require a fresh check before each attempt.

It hops through probes before the run,
Then tests each path when checks are done.

for immutable declarations that are in scope and not reassigned before .agent()
runs; leave mutable or reassigned identifiers unresolved so they require a
waiver.
- Around line 90-93: Update scanTypeScript to count named-agent declarations
where either cli or model fails to resolve, and include that count in its
returned result. In the test that consumes scanTypeScript, assert the count is
zero so incomplete declarations fail even when other named agents are complete.

Getter inventory misses paired setters

Medium Severity

The new object-literal getter walk treats the first same-name member in reverse order as definitive. A later set accessor shares that name, so lookup returns without reading the getter. A get/set pair therefore hides the getter value and the worker or flow call is omitted from the shipped-source inventory.

HOLD at exact head c69f9b2.

Substantive unresolved-spread inventory gap: a statically known trailing reflective-writer source is discarded when an unresolved spread occurs earlier in the .apply argument array.

Worker repros followed by box.run("review", {task:"x"}) return calls: 0, missing: 0, unresolved: []:

  • declare const extras:any[]; Object.assign.apply(Object, [box, ...extras, {run:f.agent}])
  • declare const extras:any[]; Reflect.apply(Object.assign, Object, [box, ...extras, {run:f.agent}])

The target remains deterministically box, and the final object is always an Object.assign source regardless of the spread length, so its known f.agent storage must be inventoried. Imported-flow analogs with trailing {define:surface.flow} return invalidFlowHeaders: 0.

Cause: staticArrayElements returns immediately when it cannot resolve a spread and preserves only the prefix; it never visits statically known trailing elements. Direct Object.assign(box, ...extras, {run:f.agent}) correctly fails closed.

All prior direct/destructuring/globalThis/helper-composition/nested-Reflect.apply/accessor/alias/branched-apply repros now pass. Evidence: focused 7-file Vitest gate passed 167/167; npm run typecheck and npm run typecheck:tests passed. Final guard: PR OPEN, exact base/head, local HEAD aligned, worktree clean.

P2 Badge Trace reflective-write targets returned from local calls

Fresh evidence beyond the fixed identifier aliases is const identity = (x: any) => x; Object.assign(identity(box), { run: f.agent }); box.run('review', { task: 'x' }): the call returns box at runtime, but this branch rejects every non-member call expression, so the member write is never associated with box and the unpinned worker invocation disappears from the inventory. Propagate return provenance through local calls used as reflective-write targets, or conservatively retain the later member call as unauditable.

Fresh evidence beyond the fixed plain aliased map is const descriptors = { ...{ run: { value: f.agent } } }; Object.defineProperties(box, descriptors); box.run('review', { task: 'x' }): objectLiteralCandidates returns the outer literal, but this loop skips its SpreadAssignment, so no write to box.run is recorded and the runtime worker call bypasses the model inventory. Expand statically known descriptor-map spreads, or fail closed when a descriptor key may be hidden behind one.

P2 Badge Break the circular provenance-module imports

Move the shared aggregate primitives behind an acyclic boundary: this import makes binding-provenance depend on binding-values, while binding-values imports binding-provenance, and binding-provenance also imports member-writes, which imports it back. The split therefore leaves multiple circular modules whose initialization safety depends on none of the imported helpers being called during module evaluation, making later provenance changes unusually fragile and defeating the intended single-purpose separation.

Fixed in 1e12307. Provenance is now layered acyclically: raw bindings and assignments are leaf dependencies; binding-value evaluation sits above them; base aggregate resolution feeds callable and intrinsic decoding; reflective member writes consume those lower layers; and all-candidate aggregate resolution is the top layer. No lower module imports back from a higher layer, and every related module remains below 500 lines.

Fixed all exact-head c69f9b2 findings in 1e12307. Static array decoding now preserves every resolvable branch and statically known suffix after unresolved spreads; paired setters no longer mask callable getters; reflective-write targets follow local-call return parameters; defineProperties expands descriptor-map spreads; and provenance modules now form an acyclic dependency stack. Worker mutations total 215 and invalid flow headers total 135. Captured evidence: focused SDK 9 files / 207 tests passed; npm run typecheck and typecheck:tests exited 0; git diff --check passed. Every provenance module remains below 500 lines. Live base/head/local/remote are aligned, the PR is open, and the worktree is clean. All reviews of c69f9b2 and earlier are superseded.

HOLD at exact head 1e12307.

Substantive local identity-call target gap: reflective target provenance follows a directly returned formal parameter/member, but not a returned local alias, assignment alias, or wrapped branch of that parameter.

Worker repros followed by box.run("review", {task:"x"}) return calls: 0, missing: 0, unresolved: []:

  • function identity(value){ const alias=value; return alias } Object.assign(identity(box), {run:f.agent})
  • function identity(value){ let alias; alias=value; return alias } Object.assign(identity(box), {run:f.agent})
  • function identity(value){ return flag ? value : value } Object.assign(identity(box), {run:f.agent})

Imported-flow analogs using {define:surface.flow} return invalidFlowHeaders: 0.

Cause: memberAssignmentPaths handles CallExpression returns by passing the returned expression through memberPath, then maps it only when that exact symbol is a formal parameter. It does not resolve returned local aliases through declarations/assigned values or wrapped branches back to the parameter. This regresses the existing transitive returned-receiver alias/assignment contract.

All accepted HOLD repros for unresolved spread suffixes, paired accessors, helper/Reflect.apply composition, nested Reflect.apply, descriptor spreads, direct identity targets, and globalThis now pass. The shipped-source helper import graph is acyclic and all 17 modules are below 500 lines (largest 477).

Evidence: focused 9-file Vitest gate passed 234/234; npm run typecheck and npm run typecheck:tests passed. Final REST + remote-ref guard: PR OPEN/non-draft, exact base/head, remote pull ref and local HEAD aligned, worktree clean.

Computed binding keys lose provenance

High Severity

The local staticPropertySegment no longer follows binding aliases or logical/await branches, and it mutates the caller seen set. Computed destructuring keys such as a renamed const or nested { [key]: { [key]: run } } fail to resolve, so bindingSource drops the pair and f.agent / f.llm aliases skip inventory.

Descriptor maps miss member writes

High Severity

objectLiteralCandidates now uses singular aggregateExpressionValue, which does not consult assignedMemberValues. A descriptor map stored only through a member write is invisible to defineProperties / defineProperty provenance, so later box.define / box.run calls are not inventoried.

Returned targets drop captured bindings

Medium Severity

The new call-expression path in memberAssignmentPaths follows a returned identifier only when it is a parameter. A helper that returns a captured target yields an empty path, so Object.assign(getBox(), …) never links the write to box.

Base aggregate skips member-assigned aliases

High Severity

baseAggregateExpressionValues omits assignedMemberValues, and callable/global/intrinsic matching now uses only that helper. An intrinsic stored as helpers.assign = Object.assign is not recognized, so later helpers.assign(box, { run: f.agent }) writes never enter inventory.

P2 Badge Expand wrapped local-call return targets

Fresh evidence beyond the fixed direct identity(box) case is a local helper such as function choose(value) { return flag ? value : other; }: Object.assign(choose(box), { run: f.agent }) can mutate box at runtime, but the conditional return is neither a memberPath nor a shape handled by memberAssignmentPaths, so box.run('review', badOptions) contributes no inventory entry. Recurse through conditional/logical/comma/await return branches here, or conservatively retain the resulting member call as unauditable.

P2 Badge Resolve aliased descriptor getters

Fresh evidence beyond the fixed inline accessor forms is const getter = () => f.agent; Object.defineProperty(box, 'run', { get: getter }); box.run('review', badOptions). This branch extracts returns only when the get initializer is syntactically an inline arrow/function; an identifier getter falls through to the nonexistent descriptor value, so the runtime worker call disappears from the inventory. Follow local getter aliases and their return provenance, or classify the installed property as unauditable.

P2 Badge Split the binding-value resolver before extending it

This newly added module is already 477 lines, again approaching the repository's explicit 500-line design-smell boundary after the earlier provenance split. It combines computed-property resolution, object/aggregate traversal, binding defaults, assignment candidates, static array expansion, and call-argument expansion; split the member/aggregate and array/call concerns so the next provenance fix does not immediately push this module over the enforced limit.

Fixed all exact-head 1e12307 findings in 49eedbe. Local-call reflective targets now retain returned const/assignment aliases, equivalent wrapped branches, and captured roots; direct member assignments feed intrinsic aliases and descriptor maps into base aggregate provenance; computed binding keys resolve through immutable aliases/bindings/wrappers; aliased descriptor getters contribute returned callables. The provenance split is acyclic across 20 helper modules; the largest is 446 lines. Worker mutations total 226 and invalid flow headers total 146. Captured evidence: focused SDK 9 files / 207 tests passed; npm run typecheck and typecheck:tests exited 0; git diff --check passed. Live base/head/local/remote are aligned, the PR is open/non-draft/mergeable, the worktree is clean, and unresolved review-thread count is zero. All reviews of 1e12307 and earlier are superseded.

@khaliqgant, I’ll request a fresh full review of #584 against base 66eb9a932239af0a4d2e318b64607010b1f6c474 and head 49eedbec32474df86f8034f97ce0e85c7bd38fe5. Earlier review state is stale for this head.

The review should cover the complete changeset. It should focus on the provenance and module-boundary cases you listed, extension budget composition, custom-wrapper identity, flow and worker inventory, approval-only behavior, readiness entrypoints, and the model, budget, generator, and readiness contract.

✅ Action performed

HOLD — substantive provenance gap remains at exact head 49eedbe.

Local identity-call receiver targets are not mapped through three statically analyzable formal/actual shapes:

  1. Rest formal: function id(...values) { return values[0] }; Object.assign(id(box), { run: f.agent }); box.run(...)
  2. Destructured formal: function id({ value }) { return value }; Object.assign(id({ value: box }), { run: f.agent }); box.run(...)
  3. Static spread actual: function id(value) { return value }; Object.assign(id(...[box]), { run: f.agent }); box.run(...)

Each worker mutation is incorrectly trusted with calls=0, missing=0, unresolved=0. Imported-flow analogues using surface.flow likewise produce invalidFlowHeaders=0, calls=0, unresolved=0. The CallExpression branch in memberAssignmentPaths maps only identifier parameters by exact symbol and indexes raw arguments, so it does not carry rest-member paths, binding-pattern paths, or expand statically known spread actuals. These are conservative inventory bypasses and should fail closed or resolve correctly.

Previously accepted HOLD reproductions replayed cleanly at this head: returned const/assignment/wrapped/captured/nested local targets; member/nested intrinsic aliases; computed/logical/nested keys; aliased/assigned descriptor getters; spread descriptor maps; unresolved-spread suffixes; accessor pairs; nested Reflect.apply.

Validation: focused SDK contract gate 9 files / 234 tests passed; npm run typecheck passed; npm run typecheck:tests passed. Provenance helper graph: 20 modules, no cycles, maximum 447 lines, none over 500.

Immediately before recording: PR OPEN/non-draft; base 66eb9a9; GitHub/remote/local head all 49eedbe; worktree clean.

P2 Badge Follow direct member writes through receiver aliases

Fresh evidence beyond the fixed direct box.run = f.agent case is const box: any = {}, alias = box; alias.run = f.agent; box.run('review', badOptions): direct writes are indexed under the syntactic root symbol (alias), while this lookup queries only box, so the runtime worker contributes no inventory entry. The same gap affects aliased member assignments of flow constructors, intrinsic writers, and descriptor maps; resolve equivalent receiver roots or conservatively retain the later call as unauditable.

P2 Badge Map defaulted local-call return parameters to their targets

When a reflective target is returned through a defaulted parameter, such as function target(value = box) { return value; } Object.assign(target(), { run: f.agent }); box.run('review', badOptions), the parameter is found but its missing actual argument makes this branch return no target path. The write is therefore never associated with box, and the runtime worker—or analogous flow constructor—disappears from the inventory; map parameter defaults (and other formal-to-actual shapes) or fail closed on the resulting member call.

P2 Badge Fail closed on unresolved computed binding keys

A mutable but runtime-known key such as let key: string; key = 'agent'; const { [key]: run } = f; run('review', badOptions) is rejected by this resolver because it accepts only const initializers, after which bindingSource drops the binding entirely. The executed worker contributes zero inventory calls, and the equivalent flow binding bypasses budget validation; trace assignment candidates or classify calls through unresolved computed bindings as unauditable rather than ignoring them.

Computed keys miss wrapped sources

Medium Severity

The new computed-key walker only follows const variable literals and raw object or array literals. A key sourced from a conditional, logical wrapper, or binding alias never resolves, so bindingSource fails. Worker inventory has no fallback and drops that agent/llm call, which lets an unpinned pair through the shipped-source gate.

The review should cover the complete changeset. It should focus on formal-to-actual mapping, static spread arguments, receiver aliases, computed-key resolution and fail-closed behavior, cycle termination, test typechecking, and helper-module boundaries. It should also check extension budgets, flow and worker inventory, approval-only behavior, readiness entrypoints, and the full model, budget, generator, and readiness contract.

Rest formals drop returned member paths

Medium Severity

Rest-parameter forwarding concatenates formalPath with returnedMember.path, then treats every segment after the index as a value lookup and passes an empty suffix. Ordinary parameters keep the returned member path as a suffix on the actual, so return value.nested still attributes the write to the argument. return values[0].nested does not, so Object.assign(id(box), …) is recorded on the rest formal instead of box and the later box.nested call drops out of inventory. String indexes such as values['0'] also fail because the offset check requires a number instead of canonicalArrayIndex.

Array rest bindings lose start offset

Medium Severity

bindingNamePaths forwards an array-rest element on the parent path and never records the rest start index. A formal such as [skip, ...rest] therefore treats rest[0] as offset 0 of the original array instead of 1. Writes through that returned value attach to the wrong slot or the rest binding, so the corresponding worker or flow call is not inventoried.

P2 Badge Apply defaults to explicit undefined actuals

When a local helper is called with an explicit undefined, such as function target(value = box) { return value; } Object.assign(target(undefined), { run: f.agent }); box.run('review', badOptions), JavaScript uses the parameter initializer, but this mapping selects the undefined expression rather than parameter.initializer. The reflective write is therefore not associated with box, so the worker invocation disappears from the shipped-source inventory and an unsupported model pair can pass the gate; recognize statically undefined actuals as default-triggering or retain the call as unauditable.

P2 Badge Preserve alternate statically expanded spread actuals

For a spread such as id(...(flag ? [other] : [box])), staticArrayElements returns both branches, but this function appends only the primary spread.values and discards spread.alternatives. Consequently Object.assign(id(...(flag ? [other] : [box])), { run: f.agent }); box.run('review', badOptions) omits the runtime worker path when the alternate branch is chosen; expand every static candidate or conservatively classify the affected invocation as unauditable.

P2 Badge Resolve assigned keys in direct member writes

An assigned computed key such as let key: string; key = 'run'; box[key] = f.agent; box.run('review', badOptions) is unresolved here because this static-key resolver follows bindings and const initializers but not assignment candidates. sourcesAtTarget then drops the direct write, so the executed worker contributes no inventory entry; use the assignment-aware key resolution already available to binding provenance or fail closed on the later member call.

P2 Badge Follow assigned receiver aliases for direct writes

Fresh evidence beyond the fixed immutable declaration alias is const box: any = {}; let alias: any; alias = box; alias.run = f.agent; box.run('review', badOptions): receiver-root discovery follows only binding and variable initializers, so the write is indexed under alias but never under box. The runtime worker invocation consequently disappears from the inventory; follow assignment-derived receiver roots or retain calls through the original aggregate as unauditable.

HOLD - substantive receiver-alias provenance bypass remains at exact head 638d4be.

directMemberPaths repairs only the simple immutable const alias = box form. Definite writes through assigned, wrapped, destructured, and aggregate aliases are still not attributed to the original receiver.

Representative worker:

declare const f: any;
const box: any = {};
const holder = { alias: box };
holder.alias.run = f.agent;
box.run("r", { task: "x" });

Flow analogue:

import * as surface from "@relayflows/surface";
const box: any = {};
const holder = { alias: box };
holder.alias.define = surface.flow;
box.define("x", { budget: "$2" }, () => {});

Literal repro command:

TMPDIR=/dev/shm bun -e "import{writeFileSync,rmSync}from\"node:fs\";import{scanTypeScript as s}from\"./tests/helpers/shipped-source-typescript.ts\";const cases={worker:\"declare const f:any;const box:any={};const holder={alias:box};holder.alias.run=f.agent;box.run(\\\"r\\\",{task:\\\"x\\\"});\",flow:\"import * as surface from \\\"@relayflows/surface\\\";const box:any={};const holder={alias:box};holder.alias.define=surface.flow;box.define(\\\"x\\\",{budget:\\\"\$2\\\"},()=>{});\"};for(const[n,src]of Object.entries(cases)){const p=\"/dev/shm/638d-\"+n+\".flow.ts\";writeFileSync(p,src);const x=s(p);console.log(JSON.stringify({n,calls:x.calls,missing:x.missing.length,unresolved:x.unresolved.length,invalidFlowHeaders:x.invalidFlowHeaders.length}));rmSync(p);}"

Captured output:

{"n":"worker","calls":0,"missing":0,"unresolved":0,"invalidFlowHeaders":0}
{"n":"flow","calls":0,"missing":0,"unresolved":0,"invalidFlowHeaders":0}

The same zero-inventory result reproduces for let alias; alias = box, const alias = flag ? box : box, logical wrappers, array aggregates, binding-element aliases, assigned destructuring, and Object.assign(holder.alias, ...). Cause: directMemberPaths follows identifier declarations and bindings only into identifier or member syntax, not assignedValues, wrapped branches, or aggregate member values.

The prior 49eed HOLD cases now pass: rest, destructured, and default formal mapping; statically expanded spread actuals; computed-key sources; cyclic descriptor/getter termination.
