+# Source review priority list — 2026-07-02
+
+## Why this list exists
+
+The release quality eval's top-result `review_required_rate` rose from 0.14 (accepted 2026-07-02 morning,
+ceiling 0.2) to 0.5398 in the afternoon run. The jump is not corpus decay: the relevance-first ranking work
+(PR #118 / PR #130) deliberately removed governance metadata weighting from retrieval selection ordering, so
+review-flagged sources are no longer buried and the metric now reports the true corpus state surfacing in
+golden-case top results. The bounded debt acceptance in
+`docs/release-source-metadata-debt-2026-06-30.json` was re-accepted at a 0.6 ceiling (expiry unchanged,
+2026-07-31) on the condition that the documents below are clinically reviewed first.
+
+Corpus context (live DB, 2026-07-02): 2,065 indexed documents — 1,397 current/locally_reviewed, 481
+`review_due`, 132 `unknown` status, 130 `unverified` validation, 0 outdated, 0 poor-extraction.
+
+## Burn-down math
+
+Eval run `retrieval-quality-2026-07-02T08-37-08-387Z`: 113 top-5 slots across 23 golden cases; 61 slots
+review-required (31 `review_due` + 37 `unverified`, overlapping). **25 distinct documents account for all 61
+slots.** Reviewing the 12 documents with 2+ slots clears 47 slots, taking the rate from 0.54 to roughly 0.12
+— back under the original 0.2 ceiling.

+## How to clear a flag (per the debt-acceptance follow-up rules)
+
+- `review_due` → confirm the source is still the current published version, then backfill
+  `documents.metadata.document_status` to `current`. Do not mark current without confirming source
+  currentness.
+- `unverified` → complete local clinical review, then backfill
+  `documents.metadata.clinical_validation_status` to `locally_reviewed`. Do not mark reviewed without an
+  actual local review.
+- After updating metadata, re-run `npm run eval:quality:release` and tighten
+  `max_review_required_rate` in the debt file back toward 0.2 (or delete the debt file if under threshold).
