governance(acv2): authorize projection-job canonical migration closure

[laiqian0239-glitch]

Work package

ACV2-DOMAIN-EVENT-PROJECTION-JOBS-CANONICAL-MIGRATION-CLOSURE-V1

Independent base-owned closure required before Learned Policy PR #372 may resume.

Fresh trusted base

• main: 915c487784d991e5c683daa6e167950f310b9a47
• authorization branch starts exactly from that commit
• authorization diff: exactly one governance JSON

Root cause

domain_event_projection_jobs remains a durable restart-safe projection recovery table, but its historical Schema 16 definition binds event_id to legacy domain_events(event_id). ACV2 has since made canonical_event_headers the sole canonical event ledger. The current Schema 21/22 ACV2 migration contracts do not canonicalize that still-live job table.

Historical migration IDs/checksums are immutable, so the repair is a new forward-only Schema 23 migration—not an edit to Schema 16/21/22 and not a runtime worker patch.

Exact future implementation scope

Exactly three paths:

• backend/lib/r32SqliteStore.js
• backend/migrations/architectureClosureV2DomainEventProjectionJobsCanonical.js
• backend/tests/architectureClosureV2/wpA/domainEventProjectionJobsCanonicalMigration.test.js

Path-set SHA-256: 001a5da8b5de2f1a740c5ad796301b58fd6101f81ec6d1ca878196d9bad07945

The mandatory first implementation commit is test-only and changes exactly the one ACV2 regression test path.

Learned Policy isolation

PR #372 remains frozen at fb1beeb0e39ad4d6263f71b4c995eb5ec663e6e2 until this authorization and the subsequent implementation closure ordinary-merge. No closure commit may be cherry-picked/rebased into #372; after closure merge, #372 is reconciled as an ordinary successor from fresh main.

Boundary

This proposal grants no implementation authority before its own ordinary two-parent merge. No dependency, workflow, package/lock, product runtime, projection-worker, release or publish change is authorized.

Summary by CodeRabbit

• Documentation
  • Added governance documentation for the ACV2 canonical migration.
  • Defined safeguards to preserve existing job data and claim indexes during migration.
  • Established forward-only, repeatable execution with fail-closed handling for orphaned jobs.
  • Documented validation, isolation, failure-recovery, and change-control requirements to support safe operation.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

The change adds a governance authorization document for the ACV2 Schema 23 migration of domain_event_projection_jobs. It defines the approved implementation scope, data-preservation rules, orphan handling, validation requirements, and release restrictions.

Changes

ACV2 canonical migration authorization

Layer / File(s)	Summary
Authorization scope and implementation baseline governance/layered-ci/acv2-domain-event-projection-jobs-canonical-migration-v1-authorization.json	Defines the trusted baseline, activation conditions, authorized paths, checksums, required commits, and prohibited repository or runtime changes.
Schema 23 migration contract governance/layered-ci/acv2-domain-event-projection-jobs-canonical-migration-v1-authorization.json	Requires R32 registration, canonical foreign-key replacement, preservation of job data and claim indexes, idempotency, checksum pinning, and fail-closed orphan handling.
Validation and governance closure governance/layered-ci/acv2-domain-event-projection-jobs-canonical-migration-v1-authorization.json	Defines merge, testing, reconciliation, authorization precedence, exact-path enforcement, and disabled production or release actions.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 33072

The PR adds an authorization document but omits a required adoption-mode field, causing the governance gate to fail. The change is otherwise localized, but it is not merge-ready until the field is added and checks pass.
