docs(db): update the remediation board — Phases 1.2, 2, 6 landed; Phase 3 reframed (#316)

[BigSimmo]

Summary

• Updates the remediation status board (docs/database-remediation-coordination.md) to the verified state at main173ea9f28: Phase 1.2 complete (PR docs(db): Phase 1.2 RPC divergence dossier — all ten match_* mismatches classified (#316) #2087 — all ten match_* mismatches are attribute-only SET work_mem), Phase 2 complete with PR Replay the migration chain onto staging to parity, and record that the chain does not reproduce schema.sql (Phase 2, #056) #2093 open (staging at 194/194 parity; check:drift vs staging red because the migration chain does not reproduce schema.sql), Phase 6 repo-side complete (PR feat(db): migration-history probe, guard-migration contract, and index-monitoring ratchet (remediation Phase 6) #2058, 6.1 migration not deployed).
• Reframes Phase 3 as repo-side codify work (no eval-canary trigger from the dossier) and records the three owner decisions it needs (work_mem values, canary exemption, 6.1 deploy window) plus the pending inbox/reconcile state.

Docs-only. No code, schema, migration, RAG surface, or provider call.

Verification

• npx prettier --check docs/database-remediation-coordination.md → All matched files use Prettier code style!
• npm run docs:check-links → docs link check passed: 1866 repo path references resolve.

Warning

Review limit reached

You’ve reached a temporary PR review limit under our Fair Usage Limits Policy.

Your recent review volume is higher than typical usage, so adaptive limits are currently applied.

Next review available in:27 minutes

Limit details: You’ve used all 1 included review currently available under your plan. You completed 101 included PR reviews in the past 7 days; at that activity level, included reviews refill at 1 review per hour.

Your organization has reached its usage spending cap. Adjust your spending cap in the billing tab.

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 PR updates the database remediation coordination board with current phase status, evidence, decisions, and ledger notes. It also adds a dated review record that documents commit verification and passing formatting and link checks.

Changes

Database remediation coordination

Layer / File(s)	Summary
Remediation board status update docs/database-remediation-coordination.md, docs/branch-review-records/*.record.md	The board now records current remediation phases, staging parity, RPC classification, reconciliation scope, Phase 6 deliverables, owner decisions, ledger state, and updated evidence. The review record documents commit and pull request verification plus passing Prettier and documentation-link checks.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk:🔵 Low · up to 34bb7

The board could imply that the canary exemption is finalized even though owner approval is still pending, which may cause coordination errors. The PR is otherwise mergeable, but the status wording should be corrected or explicitly accepted.
