A server booting on rules already installed only reconciled the whole-shape regions of the OpenFGA store, so a store restored to another point than Postgres kept answering for owner and membership facts the database no longer holds and missed the ones it gained. This builds R70 decision 6. Every adopted boot now hands subql's OpenFgaPolicy::reconcile_store (subql #139, already in the pin) every keyed fact and every group replay, and the store comes back equal to the database before the server serves. Nothing is written until every difference is known, so a failed boot retries safely, and a store that already matches costs one read and no writes.

The new live test an_adopted_boot_reconciles_a_store_left_at_another_point moves the database while the store stays put, and fails against the whole-shape-only path because the deleted row's fact stays and the new row's never arrives. a_second_boot_reconciles_the_installed_model now also checks that an unchanged store is left untouched. The plan's R70 section and chapter 20 mark decision 6 as built, so R70 now waits only on R75 for step 2's frontier leg.

Adopted boots reconciled only whole shape regions, so keyed facts could remain inconsistent with Postgres. A database restore could leave stale grants active or omit grants that exist in the database.

The fix reconciles the full OpenFGA store against Postgres before the server serves. It finds all differences before writing and changes only mismatched facts. If the store already matches, reconciliation makes no writes.

📝 Walkthrough

Adopted OpenFGA models now reconcile keyed and whole-shape facts against Postgres during boot. Reconciliation determines differences before writing and returns added and removed counts. Tests cover fact changes and reconciliation failures, and deployment documentation describes restore behavior.

Changes: Store reconciliation

Layer / File(s) Summary
Reconcile keyed and whole-shape facts
crates/connetto-server/src/openfga.rs
reconcile_store replaces reconcile_materialised. It reconciles keyed and whole-shape facts, writes differences after determining them, and returns added and removed counts.
Wire reconciliation into adopted-model boots
crates/connetto-server/src/builder/mod.rs, crates/connetto-server/tests/it/*, docs/architecture/20-deployment.md, plans/master-implementation-plan.md
Adopted-model boots call reconcile_store and log the counts. Integration tests verify that stale facts are removed, missing facts are added, a second reconciliation makes no changes, and store or fact-query failures return SetupError::Store. Documentation and the implementation plan describe the updated behavior.

Adopted boots now bring the whole OpenFGA store in line with the database before serving. The deployment chapter now consistently describes this as built. No concrete merge-blocking defect remains at the current head.

Full details: Docstring Coverage

Explanation

Docstring coverage is 100.00% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 9 functions across 4 files. (2 skipped: 2 unsupported.)

Full details: No Placeholder Implementations

Explanation

No added line in the six changed files contains todo!, unimplemented!, the specified panic! placeholders, NotImplementedError, a not-implemented throw, or a new TODO, FIXME, HACK, or XXX comment. The added Rust code is executable reconciliation logic and tests.

Full details: No Blanket Diagnostic Suppression

Explanation

No added line matches the prohibited blanket suppressions. The Rust changes add no allow, deny, or warning-level suppression attributes. The added expect calls are runtime test assertions, not diagnostic suppression directives.

Full details: Behavior Change Carries A Test

Explanation

The pull request changes runtime behavior in crates/connetto-server/src/builder/mod.rs and src/openfga.rs. It also changes test files under crates/connetto-server/tests/, including tests for adopted-boot reconciliation, zero changes, and reconciliation failures.

Full details: Git Dependency Pin Stays Out Of Commits

Explanation

Cargo.lock is unchanged in the reviewed pull-request range, so the failure condition does not apply. The repository does contain bare git dependencies, but they cannot fail this check without a Cargo.lock change.

Full details: Pre-Alpha Has No Deployments

Explanation

The workspace package version is 0.0.0, so the pre-alpha rule applies. Added lines contain no migration guide, migration SQL, upgrade path, existing-deployment, version-bump, rollout, deprecation, compatibility-shim, or old-client-alias wording. The startup refusal describes an unreconcilable store, which the check explicitly permits.

Full details: Prose Punctuation

Explanation

Added prose contains no semicolons, em dashes, en dashes, punctuation hyphens between words, curly quotes, or ellipsis glyphs. Semicolons in added lines are code terminators, and hyphens occur only in compound words or identifiers.

🟡 Minor · Chapter 20 contradicts itself about the boot reconcile. · 20-deployment.md:27

docs/architecture/20-deployment.md:27
📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Chapter 20 contradicts itself about the boot reconcile.

Line 56 now states the whole-store reconcile is built (R70, 2026-10-06). Two unchanged lines still state the old behavior:

  • Line 27 says an adopted model "reconciles only its whole-shape regions".
  • Line 66 says "Decided (R70), not built" for the same behavior.

Update both lines. Make line 27 say an installed model reconciles the whole store. Remove line 66, or mark it Built (R70). The header at line 43, "Built defective for authorization, whose fix is Decided (R70), not built", also needs a check against the new status.

As per path instructions for **/*.md: the chapter must keep one consistent account of what is built.

Also applies to: 66-66

@coderabbitai Chapter 20 now gives one account. The OpenFGA row says an installed model reconciles the whole store against Postgres, the restore heading reads "Built for rows, logins, authorization and the chunk store" and cites an_adopted_boot_reconciles_a_store_left_at_another_point as the proof, and the "Decided (R70), not built" line is gone. The same push adds an_adopted_boot_that_cannot_reconcile_refuses, which covers the boot refusing when the store or the facts cannot be read.

@LucaCappelletti94 The documentation concern is addressed.

The new test asserts reconciliation errors for unreadable facts and an unknown store. It does not call the builder, but the adopted startup path propagates those errors with ?.

I verified the source. I did not run the tests.
