Evidence

Evidence: demonstrated — a local Next.js application against an isolated local PostgreSQL instance, exercised at this head: requests with no credential and with a wrong credential returned the rejected shape, the configured credential returned the healthy shape, a second authorized call inside the shared interval returned the identical evaluation timestamp with no database statements logged for it (a control statement confirmed logging was live), and a fresh evaluation after the interval returned the alert result for seeded recent reviews. The regenerated migration applied on a fresh database and the detector window query planned as an index scan on the new index.

Changes

• Define the monitor credential through the existing server environment configuration.
• Share a 60-second evaluation result per application instance, including its response status and timestamp.
• Add a concurrent index for the detector time window while retaining timestamp fallback semantics and alert thresholds.
• Document owner-operated configuration, deployment, and rotation.

Verification

At the current head:

• The branch migration is generated at the next free sequence position after the merged default branch (0302_regular_maverick), its generated DDL is unchanged, and a subsequent drizzle-kit generate reports no schema drift.
• That migration applied on top of the merged default-branch migration chain on a fresh database, and the bootstrap check passed; the resulting index exists with the expected definition and is valid and ready.
• Detector window query plan on the merged tree: with sequential scans disabled on the local instance, the planner resolves the window predicate through a bitmap index scan on the new index, which confirms the index predicate matches the detector filter. This is a usability check, not a cost comparison against production data.
• Database package suite: 50 tests passed. Focused route and detector suites: 41 tests passed.
• Running web application against that database:
  • No credential and a wrong credential each returned the rejected shape with status 401.
  • The configured credential returned status 200 with the healthy shape.
  • The first evaluation in the interval logged six detector statements; a second authorized call two seconds later returned the same evaluation timestamp and logged none, while a control statement was recorded on the same connection log.
  • After the interval elapsed, a fresh evaluation ran and returned status 503 with the alert result for the seeded recent reviews.
• Carried over from the earlier head whose index DDL is identical (this head only renumbered the migration): over a large synthetic history the index resolved the recent rows by bitmap index scan in a few milliseconds; not re-measured at this head.
• No visual surface changed. Production monitor configuration was not exercised or modified.

Production prerequisites

Apply packages/db/src/migrations/0302_regular_maverick.sql (the detector window index) before application deployment. The owner must run pnpm web:env set CODE_REVIEW_HEALTH_SECRET and coordinate the application deployment with the external monitor's bearer header update. See ENVIRONMENT.md.

Proxy answers

The owner's proxy gave these answers in the owner's place.

1. Question: Monitor contract: Plan decision: use a dedicated CODE_REVIEW_HEALTH_SECRET with Authorization: Bearer, preserve detector policy, add a 60-second per-instance shared evaluation, and document an operator-coordinated provisioning/deploy/monitor update. The monitor configuration is outside this repository, and this session will not change production. Which transport and rollout contract should this PR adopt?
   Answer: Bearer header; coordinated cutover
   Confidence: 0.60 · Precedent: Replace old paths instead of keeping them alongside: session ad6a3f589364, "alongside? why not instead?"; record any real external gap in the PR: session 55c9c80332a7
2. Question: Review recovery: The merge commit has green CI and no current-head Kilo Code Review check; the prior head's review was approved, and its generated detector migration matches byte-for-byte after index regeneration. How should I resolve the missing current-head review?
   Answer: Retry on review page
   Confidence: 0.85 · Precedent: Never accept "blocked" or "failed" as an end state: session 55c9c80332a7, "blocked is not an acceptable end state"; Do the least work possible: session 00eb2a1d3e4b, "do not redo work that was already done"
3. Question: Review fallback: The review page redirects this VM to sign-in, so I cannot use its retry action. The merge commit adds main plus the regenerated migration; its DDL is byte-identical to the reviewed migration, and the prior review summary is clean. How should I proceed?
   Answer: Use prior clean review
   Confidence: 0.80 · Precedent: Regrade only after meaningful changes: session 55c9c80332a7, "regrading should only happen if there were meaningful changes". A main merge with byte-identical migration DDL is not meaningful. Also, blocked is not an acceptable end state: "blocked is not an acceptable end state".

Code Review Summary

Status: No Issues Found | Recommendation: Merge

Executive Summary

The new delta renames the redundant code-review window index migration to 0302_regular_maverick after merged main's 0300/0301, with byte-identical DDL, an intact snapshot prevId chain, a unique journal index sequence, and an index name still matching the detector query.

Assumptions: [INFERENCE] Migration apply and drizzle-kit generate were not executed in this read-only review. The large incremental range includes merged main changes (device auth, contributor credits, mobile/i18n, etc.) that this PR did not author; only the migration renumbering and PR body update are new PR changes. Generated snapshot/journal contents were checked for chain and index consistency rather than line-reviewed. The external monitor bearer-header cutover and CODE_REVIEW_HEALTH_SECRET provisioning remain operational steps documented in ENVIRONMENT.md.

Verification

• _journal.json indexes are contiguous 0..302 with 0302_regular_maverick appended after main's 0300/0301 and monotonically increasing when.
• 0302_snapshot.json prevId equals 0301_snapshot.json id, and the snapshot carries both main's new columns and the new index.
• idx_cloud_agent_code_reviews_started_at_effective appears only in 0302_regular_maverick.sql, its snapshot, and packages/db/src/schema.ts; no orphaned 0300_secret_the_phantom.sql remains.
• The migration SQL is a 100% rename of the previously reviewed file, and its expression/predicate still matches startedReviewsCteSql in detectors.ts.

Previous review (commit 59a98ef)

Status: No Issues Found | Recommendation: Merge

Executive Summary

The incremental delta regenerates the redundant code-review window index on the merged tree as migration 0300, after main's 0299_lame_mojo, with an intact snapshot prevId chain, no duplicate index name, and unchanged detector/route code that still matches the index expression.

Assumptions: [INFERENCE] Migration apply was not executed in this read-only review. The generated SQL is identical to the previously reviewed migration apart from the file name, the index name appears in exactly one migration plus packages/db/src/schema.ts, and the journal/snapshot files are generated artifacts excluded from review. The 0299/environment-table changes in the incremental range come from merged main, not this PR, and were not treated as PR findings. The external monitor bearer-header cutover and CODE_REVIEW_HEALTH_SECRET provisioning remain operational steps documented in ENVIRONMENT.md.

Previous review (commit 1c18d66)

Status: No Issues Found | Recommendation: Merge

Executive Summary

The incremental delta renumbers the redundant code-review window index from migration 0296 to 0299 and it now matches the merged journal, schema definition, and existing COMMIT; CREATE INDEX CONCURRENTLY ...; BEGIN; pattern with no duplicate index name.

Assumptions: [INFERENCE] Migration apply was not executed in this read-only review; the SQL is byte-identical to the previously reviewed migration apart from the file name, the index name appears in exactly one migration, and the snapshot/journal files are generated artifacts excluded from review.

Previous review (commit 347dd40)

Status: No Issues Found | Recommendation: Merge

Executive Summary

The monitor endpoint now uses a dedicated bearer secret with timing-safe comparison, a 60-second per-instance cache, and a matching partial expression index; the detector SQL rewrite preserves the prior window/fallback semantics.

Assumptions: [INFERENCE] The external monitor's bearer-header cutover and CODE_REVIEW_HEALTH_SECRET provisioning in production are operational steps outside the repository, as documented in ENVIRONMENT.md; stale monitor configuration would yield 401s. Migration execution was not run in this read-only review, but the COMMIT; CREATE INDEX CONCURRENTLY ...; BEGIN; pattern matches existing migrations (e.g. 0272, 0278), the snapshot diff is limited to the new index, and the index predicate/expression matches the detector query exactly. Promise.withResolvers used in tests is supported by the repo's Node >=24 engine.

Changes requested: the index migration is missing at the current head.

• Merge commit bc04ca0 resolved the collision with 0299_lame_mojo by deleting 0299_tidy_grey_gargoyle.sql and its journal and snapshot entries.
• packages/db/src/schema.ts still declares idx_cloud_agent_code_reviews_started_at_effective, but no migration or snapshot creates it. If merged, production never gets the index, and the next generated migration would pick up this index by accident.
• Merge the latest main, then regenerate the index migration at the next free number after main's latest migration. Use the existing COMMIT; CREATE INDEX CONCURRENTLY ...; BEGIN; pattern.
• Update the PR body's production prerequisites to name the new migration file.
• Re-run the detector query plan check and the DB tests on the merged tree.

[iscekic]

Changes requested: renumber the migration again. It collides with main.

• main now has 0301_contributor_credit_window (from fix(contributor-champions): apply the credit window to enrollment and tier changes #8701). This branch adds 0301_review_window_index, so it conflicts in packages/db/src/migrations/meta/0301_snapshot.json and meta/_journal.json.
• Merge the latest main, take main's journal and snapshots, and regenerate this migration at the next free number after main's latest migration (currently 0302).
• Three open PRs (cli-sessions: share and fork storage rules #8224, fix(reviews): share monitor evaluation results #8664, fix(auth): maintain native verification state #8845) need a new migration. Only one of them can use 0302. If another one merges first, merge main again and regenerate this migration again.
• Re-run the migration chain on an empty database and the drizzle check on the merged tree.

[iscekic]

bot: Both requests are addressed at the current head.

• Merged the latest default branch and kept its journal and snapshots; the branch migration is regenerated at the next free sequence position after it.
• The generated index DDL is unchanged and a follow-up drizzle-kit generate reports no schema drift.
• Applied the full migration chain on a fresh database and re-ran the bootstrap check; the index exists with the expected definition, valid and ready.
• Re-ran the detector window query plan check: the planner selects the new index with a bitmap index scan over the window condition.
• Database package suite and the focused route and detector suites pass.
• The PR body's production prerequisites now name the migration file.
