docs(issues): keep #248 open and track residual live drift

[BigSimmo]

Summary

• Keep ledger row #248 open. The evidence establishes that migration 20260705180000_reconcile_search_health_indexes.sql is recorded as applied while two of its canonical indexes are missing, but does not yet distinguish skipped DDL/history repair from indexes created and later dropped.
• Update the remediation plan and playbook so the approved read-only migration-history and audit check is the decision point for that cause.
• Clarify that restoring the two canonical concatenated-expression trigram indexes is confirmed drift repair. It neither implements nor pre-empts #102's separately canary-gated bare-column indexes.
• Replace the previous queued inbox requests: withdraw the closure of #248, retain it as an investigation, and track the broader P1 live-drift remediation without asserting an unproven root cause.

Verification

• JSON inbox requests parsed before commit.
• Remote branch updated atomically from 953db86 to c3990af; the commit is limited to the two remediation documents and four inbox-request changes.
• No provider, database, or production mutation was performed. CI remains the authoritative validation for this documentation-only patch.

Risk

Low. This corrects documentation and immutable inbox requests only.

Summary by CodeRabbit

• Documentation
  • Added a comprehensive database remediation plan covering drift investigation, migration history, RPC reconciliation, index restoration, validation, and safeguards.
  • Added a phased remediation playbook with safety constraints, approval boundaries, evidence requirements, and completion criteria.
  • Documented live-drift forensics and branch review outcomes.
• Issue Tracking
  • Recorded database drift findings, including missing and unexpected indexes, divergent retrieval logic, and required read-only investigation steps.

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:18 minutes

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

Added documentation for live database drift remediation. The changes define phased investigation, staging rehearsal, RPC and index repair, validation, safeguards, approval boundaries, audit evidence, and issue tracking.

Changes

Database remediation workflow

Layer / File(s)	Summary
Evidence and governance records docs/database-remediation-plan.md, docs/audit/live-drift-forensics-2026-08.md, docs/outstanding-issues-inbox/*, docs/branch-review-records/*	Defines remediation ownership, evidence requirements, approval boundaries, audit tracking, and live-drift issue records.
Investigation and staging workflow docs/database-remediation-plan.md, docs/database-remediation-playbook.md	Defines repository enablement, read-only production forensics, and staging migration-parity rehearsal procedures.
RPC and index remediation docs/database-remediation-plan.md, docs/database-remediation-playbook.md	Defines RPC reconciliation, index restoration, validation, measurement, and closure procedures.
Safeguards and deferred work docs/database-remediation-plan.md, docs/database-remediation-playbook.md	Defines migration-history safeguards, runtime coverage checks, deferred debt, sequencing rationale, and cross-session handoff tracking.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Mergeability Score:🟡 Moderate · up to c3990

The documentation currently omits decisive verification evidence, permits external actions without an explicit confirmation gate, and describes migration-history validation in a way that would not enforce the intended check. That could mislead operators or create a false sense of protection, so the PR should not merge until these bounded issues are corrected or explicitly accepted.

Summary

• Kept issue #248 open and reframed the migration cause as unresolved until read-only migration-history and audit evidence can distinguish skipped DDL from indexes created and later dropped. docs/outstanding-issues-inbox/a3dca734-d253-4c42-8edc-dc690dd140dc.jsonL5-L10
• Updated the remediation plan and playbook to avoid presenting the mark-applied hypothesis as proven, while retaining the evidence that a persisted partial migration is impossible. docs/database-remediation-plan.mdL3-L12docs/database-remediation-plan.mdL43-L56docs/database-remediation-playbook.mdL14-L20
• Clarified that restoring the two missing canonical concatenated-expression trigram indexes is confirmed drift repair and neither implements nor preempts #102’s separately canary-gated bare-column indexes. docs/database-remediation-plan.mdL107-L112docs/database-remediation-playbook.mdL57-L60docs/database-remediation-playbook.mdL177-L185
• Replaced the previous queued issue records with writer-generated inbox requests that preserve #248 and track the broader P1 live-drift remediation under the corrected hypotheses. docs/outstanding-issues-inbox/a3dca734-d253-4c42-8edc-dc690dd140dc.jsonL1-L11docs/outstanding-issues-inbox/dec50a21-f143-485d-a6b1-f9c3621013a6.jsonL1-L13
