User description

Summary

• Persist bounded generation-degradation scalars even when the public payload is unserved, preserving the telemetry implementation already merged on main.
• Measure remaining route budget from the actual deadline at completion. Treat “no more than” and “at most” equivalently for unitless, clinical-unit, and scientific quantities.
• Keep document lookup support, citations, and derived source panels aligned. Match qualifiers across each document’s chunks, exclude partial matches, and reserve a citation for each named document.
• Render TXT/PDF viewer labels accurately and test danger-source suppression in SSE evidence previews.
• Enforce worker document/MIME allowlists inside a new atomic claim RPC overload. Keep the existing unscoped RPC for older workers; document scope configuration and fail-closed rollout behavior.
• Resolve real conflicts with main without rewriting the PR history.

Areas touched: Answer engine, App experience, Source intake and indexing, Data platform and access

RAG impact: no retrieval behaviour change — fixes affect answer verification, document-list attribution, source-panel consistency, and bounded telemetry; retrieval scores and ordering are unchanged.

Verification

• Targeted regression suites: 9 passed; 295 passed (295).
• Offline RAG gate: 26 passed; 982 passed (982); fixture validation passed 36 golden cases, 26 suites, and 26 programme cases.
• Local SQL execution: 10 scoped-claim scenarios passed, including mixed queues, intersecting allowlists, eligibility changes, active sibling leases, and locked-document MIME rechecks.
• TypeScript compilation passed with zero errors after correcting a new test fixture.
• Changed-file lint and TypeScript push guards passed. Repository-wide formatting completed. Migration-role, SECURITY DEFINER grants, organisation, diff-integrity, and maintainability checks passed.
• After helper extraction, lookup/adversarial suites passed 2 files; 31 tests.
• Independent standards/specification review completed; follow-up review confirmed citation-budget and retained-source corrections.
• Expected in CI for this event/scope: PR policy, static checks, safety, coverage, ingestion SAST, build/container checks, applicable browser/Lighthouse jobs, migration replay, and the PR required aggregate.
• Hosted CI observed at faf351d7f195a3c1bc89e1819297899a8c7f2f95: production build, safety/config, ingestion SAST, Playwright build, Lighthouse, migration application, and database behavior tests passed. The job regenerated a fresh drift-manifest artifact.
• Required CI is not green: static checks and one unit partition report stale numeric-test governance evidence and the old drift manifest. A narrowly scoped engineering drift exception is committed locally and its 43 focused governance tests pass; clinical approvals and reviewed digests remain unchanged.
• Blocked: retrieving the generated drift-manifest artifact is denied by the current workspace network policy. The manifest and final governance correction still need publication followed by a fresh exact-head CI run. Container verification was still running at the last observation.
• Local image unpack failed with no space left on device; the documented local drift push override was used to reach CI without weakening required hosted gates.
• UI verification not run: no further UI edits were made during this review; fresh browser proof for the PR’s existing label changes remains assigned to the applicable hosted CI jobs.
• Provider-backed clinical/RAG evaluations and live database checks were not run. Local offline proof does not establish clinical release readiness.

Risk and rollout

• Risk: Medium. The claim fix adds a database function overload; answer-side matching intentionally excludes partial document matches.
• Rollback: Revert the PR’s application changes. Any live database rollback requires its own specifically approved migration.
• Merge gate: This PR now includes supabase/migrations/20261017175448_scope_ingestion_claim_atomically.sql. Merging to main automatically applies it to the live clinical database and deploys the app/worker. Merge only inside the owner’s specifically approved database-change window. Do not enable auto-merge for this migration PR.
• Production effects: No live mutation or deployment was performed during this review. Scoped workers require the new overload; a missing overload fails closed instead of claiming unfiltered jobs.

Clinical Governance Preflight

Synthetic evidence was used for regression tests and local SQL execution. No patient data or live clinical sources were changed. Numeric/source safeguards remain active, and retrieval scores/order remain unchanged. The new SECURITY DEFINER overload retains service-role-only execution with PUBLIC, anon, and authenticated access revoked. Local checks do not establish clinical sign-off or authorize the database merge.

Notes

• The existing three-argument claim contract remains available during rollout.
• RAG hotspot files remain within their enforced size budgets.
• Review-thread replies and resolution remain open; this task did not explicitly authorize those GitHub conversation writes.

Summary by CodeRabbit

• New Features
  • Document previews and actions now display file types based on the document’s format, including when its filename extension is misleading.
  • Document searches can return files that collectively match the requested details, with citations tied to the matching documents.
  • Worker configurations can restrict which document IDs and file types are eligible for processing.
• Bug Fixes
  • Answer checks now recognize “no more than” and “at most” as equivalent upper limits, including in clinical quantities and alcohol recommendations.
  • Worker processing now skips jobs that are not yet due or have not reached an expired lease.

CodeAnt-AI Description

Align document matches, ingestion scope, and file labels with actual evidence and file types

What Changed

• Document lookup lists only documents whose evidence covers the requested topics, and citations and source panels reflect the same matches within the five-citation limit.
• Workers can restrict claims by document and file type before jobs are leased. Invalid allowlists claim no jobs, and excluded jobs do not use attempts or block eligible jobs.
• Clinical answer checks treat “no more than” and “at most” consistently, including when checking quantities and alcohol guidance.
• Document viewer actions and previews show the file’s actual type instead of assuming every document is a PDF.
• Generation degradation details are recorded even when the related rollout is not served, with remaining route time measured at completion. Evidence previews exclude danger-level sources.

Impact

✅ Document matches cite evidence for all requested topics
✅ Scoped workers leave unrelated jobs untouched
✅ Accurate TXT, image, and document download labels

📝 Walkthrough

The pull request updates document-kind labels, RAG answer matching and evidence selection, generation-degradation logging, and worker ingestion-job claims. It adds a scoped database claim function, worker configuration and wiring, and regression tests for these changes.

Changes: Document file-kind labels

Layer / File(s)	Summary
Derive and display file kind src/components/clinical-dashboard/document-ui.tsx, src/components/DocumentViewer.tsx, src/components/document-viewer/document-overview-landing.tsx, tests/answer-source-rows.test.ts	The shared helper maps recognized MIME types to display labels, then falls back to filename detection and a default. The viewer and overview use the derived kind in their labels. Tests cover MIME-type precedence and fallback behavior.

Alcohol-limit answer matching

Layer / File(s)	Summary
Recognize equivalent limit phrases src/lib/answer-verification.ts, src/lib/rag/rag-answer-shape-checks.ts, src/lib/rag/rag-original-section-delivery.ts, tests/answer-verification.test.ts, docs/branch-review-records/*, docs/clinical-hazard-controls.json	Clinical and labelled-band checks, opening-answer checks, and adult recommendation checks accept “no more than” or “at most.” Display normalization strips “no more than” from quantity text. Delivery checks accept additional equivalent phrasing. Tests cover comparator equivalence and distinguish “at least.” The review record and hazard-control record document regression coverage and review status.
Validate source-bound alcohol summaries src/lib/rag/rag-source-bound-alcohol-summary.ts, tests/answer-verification.test.ts	Adult recommendations can pass source validation through support for the full clause or separate support for age scope and limits. The expected answer lead accepts either comparator phrase.

RAG document-support answers

Layer / File(s)	Summary
Build answers from qualifying documents src/lib/rag/rag-document-support-list.ts, src/lib/rag/rag-extractive-builder.ts, tests/rag-document-support-list.test.ts	The helper can keep documents whose chunks collectively cover every non-metadata query qualifier. It builds answer citations and sections within a five-citation budget. The extractive builder enables filtering, uses the helper’s citation IDs, and rebuilds derived artifacts when answer-source and filtered-result counts differ. Tests cover matching, citations, limits, and no-match answers.

Answer-selection checks

Layer / File(s)	Summary
Update answer-selection expectations tests/answer-stream-preview-order.test.ts, tests/rag-adversarial-harness.test.ts	The SSE preview test checks that a clean source is selected over a danger-level source. The mismatched-attribution case now uses the standard fixture expectation check instead of a registered divergence.

Generation-degradation telemetry

Layer / File(s)	Summary
Record and project degradation metadata src/lib/rag/rag-generation-degradation.ts, src/lib/rag/rag-answer-telemetry-metadata.ts, tests/rag-generation-degradation.test.ts, tests/rag-telemetry-canary-absence.test.ts	The recorder exposes a metadata projection and captures remaining route budget. Tests cover empty and populated metadata, canary-token exclusion, and timeout recording.
Attach metadata to query logs src/lib/rag/rag.ts	The RAG route supplies the remaining-budget callback and adds recorder metadata to successful-generation and generation-fallback query logs.

Worker ingestion-job claim scope

Layer / File(s)	Summary
Add scope filters to the claim RPC supabase/migrations/20261017175448_scope_ingestion_claim_atomically.sql, supabase/schema.sql, src/lib/supabase/database.types.ts, supabase/applied-migration-hashes.json, supabase/drift-manifest.json, tests/sql/ingestion-claim-scope.sql	The new RPC overload accepts optional document-ID and file-type filters. It checks job eligibility and document authority before leasing jobs. SQL tests cover scoped and legacy calls, allowlist mismatches, and due times.
Resolve and pass worker claim scope worker/behavior.ts, worker/main.ts, .env.example, tests/rag-generation-degradation.test.ts, tests/worker-row-contract.test.ts, docs/worker-deploy-runbook.md	Worker helpers normalize allowlists, resolve environment settings, and check candidate scope and claimability. The worker passes active allowlists to the RPC. Tests and deployment documentation cover configuration and claim behavior.

SessionStart pipe handling

Layer / File(s)	Summary
Handle successful dependents that close stdin scripts/claude-session-start.mjs, tests/claude-cloud-lifecycle.test.ts	The hook ignores EPIPE when a dependent exits successfully. The test covers a large SessionStart payload when dependents do not read stdin.

Merge Risk: 🔵 Low · up to 84fec

This update only records a time-limited engineering exception for the answer-verification tests. Two small open issues remain from earlier review. Worker job claims may skip documents whose stored file type has stray spaces. Some compound document-lookup answers may leave out a document that should be cited. Neither blocks the main workflows. The PR is mergeable once exact-head CI is green and these follow-ups are acknowledged.

High-Level Assessment

The following are alternative approaches to this PR:

1. Enforce worker scope inside the claim RPC

• ➕ Makes selection and claiming atomic.
• ➕ Avoids a pre-check-to-claim race and dependence on a separate candidate query.
• ➖ Requires a database-function change and deployment coordination.
• ➖ Expands the claim RPC’s contract for scoped workers.

Recommendation: The PR’s pre-check is a contained way to avoid claiming jobs when visible eligible candidates fall outside scope. If worker scope must be a strict isolation guarantee, move filtering into the claim RPC: the separate query cannot guarantee that the subsequently claimed jobs are the ones it checked.

1. Unused client-side claim filters look enforced 🟡 Low 🐞 Bug ⚙ Maintainability

Description

isPreClaimCandidateAllowed and isClaimableIngestionJobCandidate are imported into and
re-exported from worker/main.ts, but nothing calls them now that scope enforcement lives in the
five-argument SQL overload. Their unit tests in rag-generation-degradation.test.ts exercise
client-side logic that never runs. A later maintainer may assume the TS checks guard claims, or may
edit them expecting a behaviour change, while the real filtering (including the hard-coded
max_attempts ?? 3 default) can drift from the SQL.

2. Lookups cite contrary clinical guidance 🟡 Low 🐞 Bug ≡ Correctness

Description

documentLookupMetaTokenPattern removes recommend from the qualifiers that a document must match,
although it can express the clinical position the query asks for. For a query asking which documents
support and recommend anticoagulation in pregnancy, a retrieved document saying it is
contraindicated can be named and cited solely because it mentions anticoagulation and pregnancy.

Code

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

The added pattern excludes forms of recommend, while the matching loop checks only tokens left
after that exclusion. Queries beginning 'Which documents support' take the document-lookup path, and
the retained chunks become the named documents and their citations without a further recommendation
check.

1. Supported documents disappear from results ✗ Dismissed

Description

coveringChunkIds accepts early partial matches without checking whether a later chunk covers the
same qualifiers with fewer citations. When those early chunks exhaust the five-citation budget, a
fully supporting document can be omitted from the answer and source panels, or the only supporting
document can be skipped and the quality-gap answer returned.

Code

src/lib/rag/rag-document-support-list.ts[R55-59]

+      const added = (matchesByResult.get(chunk.id) ?? []).filter((token) => !covered.has(token));

Relevance

●●● Strong

Greedy covering selection can exhaust the citation budget before a later, more compact supporting
chunk.

PR-#3523

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

In the six-qualifier case, six single-qualifier chunks can be selected before a later chunk covering
all six is considered, causing the budget check to discard the only supporting document. In the

Greedy covering-chunk selection spends citations on early partial matches even when a later chunk provides the same coverage, excluding supporting documents under the five-citation limit.

## Fix Focus Areas
- src/lib/rag/rag-document-support-list.ts[49-72]
- tests/rag-document-support-list.test.ts[88-115]

## Recommended Fix
Choose a minimal or bounded-small covering set for each document before applying the citation budget, so a set of at most five chunks is used when one exists. Add regressions with single-qualifier chunks preceding an all-qualifier chunk: verify that a sole supporting document remains named and cited in the six-qualifier case, and that another complete document can be included when the smaller set leaves enough citation capacity.

2. Some document citations omit qualifiers ✗ Dismissed

Description

buildDocumentSupportListAnswer reserves one citation per named document before allocating

one supplies the query’s qualifiers across two chunks, its second chunk is omitted even though the

clock skew can make another row claimable before any per-row check; the client query also has no

7. Bad allowlists keep claim polling failing ✗ Dismissed

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
`answerLatencyMetadata` has a new optional `degradation` parameter that no caller passes. The degradation scalars are added through `generationDegradation.metadata()` instead.

## Fix Focus Areas
- src/lib/rag/rag-answer-telemetry-metadata.ts[6-10]
- src/lib/rag/rag-answer-telemetry-metadata.ts[46-57]

## Recommended Fix
Pick one path. Either remove the `degradation` parameter, its spread and the re-export, or pass `answer.generationDegradation` through it and drop the separate `generationDegradation.metadata()` spreads, keeping in mind that the public record is `undefined` when the recorder is disabled.

CodeAnt Nitpicks

4 code suggestions

1. A competing claimant can take the in-scope jobs after this snapshot; the later unfiltered claim RPC can then lease an out-of-scope job.

Race condition · worker/main.ts:406-414

---

2. compactDocumentType updates the tile and metadata, but overview buttons still show generic labels for TXT files, so the promised file-kind-specific action labels are missing.

Incomplete implementation · src/components/document-viewer/document-overview-landing.tsx:23-25

---

3. expectedLeadPattern rejects supported answers using per week or in any single day, so this renderer returns null instead of normalizing them to source wording.

Logic error · src/lib/rag/rag-source-bound-alcohol-summary.ts:327

---

4. This invalid schemaVersion makes the projector reject the fixture before checking its canary reason or attempts, so the test passes without verifying those fields are removed.

Incomplete implementation · tests/rag-telemetry-canary-absence.test.ts:132

CodeAnt PR Risk: Medium Risk

• The PR needs attention before merging because its database migration requires an approved change window.
• The runbook says merging to main changes the live database and that this PR does not authorize that change; confirm the window before merging.

Code Review ✅ Approved 4 closed / 4 findings

🔴 High risk · The new SECURITY DEFINER claim RPC migration changes database leasing and access; a scope or locking error could claim excluded jobs or consume their attempts.

Atomic scoped claim RPC overload enforces worker document and MIME allowlists, alongside citation-budget, document-lookup, MIME labeling, and telemetry fixes. Resolved this session: the pre-claim scope check that could act on stale rows, workers failing claims before the migration is applied, the stale drift manifest for the new claim signature, and the lookup 'no documents' gap when no single document matched every token. No open findings remain.

✅ 4 closed

✅ Bug: Pre-claim scope guard is check-then-act; claimed rows are never re-checked

📄 worker/main.ts:404-418 📄 worker/behavior.ts:721-735
claimJobs reads ingestion_jobs in a separate query, decides whether every eligible row is in scope, and only then calls claim_ingestion_jobs. The RPC picks candidates again on its own, by created_at, id, skipping any document that is locked. So if an out-of-scope job becomes eligible between the two calls, this worker still claims and processes it. That happens when a job is inserted, a next_run_at passes, or another worker's lease expires. Nothing checks the returned rows against WORKER_ALLOWED_DOCUMENT_IDS/WORKER_ALLOWED_FILE_TYPES afterwards. The read also has no limit, so PostgREST's row cap can hide eligible out-of-scope rows that the RPC can still reach once it skips locked documents. On top of that, a single eligible out-of-scope job anywhere in the queue makes a scoped worker return [] on every poll, so it stalls. The fix is to enforce scope where the claim happens: pass the allow-lists into claim_ingestion_jobs, or at minimum filter accepted after the claim and release out-of-scope rows through the normal fail/retry path.

✅ Bug: Worker always sends new RPC args; claims fail until migration applied

📄 worker/main.ts:404-413 📄 supabase/migrations/20261017100000_scope_ingestion_job_claims.sql:2-10
claimJobs now passes p_allowed_document_ids and p_allowed_file_types on every call, including when no scope is configured and both arrays are empty. The Railway worker auto-deploys from main, but migrations are applied by an operator (the PR notes say live migrations are deferred). Until 20261017100000_scope_ingestion_job_claims.sql is applied and PostgREST's schema cache reloads, PostgREST cannot find a claim_ingestion_jobs overload that takes these named args. It returns an error (PGRST202), claimJobs throws, and every worker stops claiming ingestion jobs. Fix: send the two scope args only when scopeFilter.active is true. Unscoped workers then keep using the existing 3-arg signature, which still works after the migration because of the defaults.

✅ Quality: drift-manifest.json not regenerated for new claim_ingestion_jobs signature

📄 supabase/migrations/20261017100000_scope_ingestion_job_claims.sql:1-15
The migration drops public.claim_ingestion_jobs(text,integer,integer) and recreates it with a 5-argument signature and a new body. supabase/drift-manifest.json still lists the old 3-argument signature with def_hash 64a776fa…. check:drift-manifest-freshness deep-compares the committed manifest snapshot against one regenerated from the migration chain, so CI will fail. If the check were bypassed, the post-merge live-drift check would go red once the migration is applied. Fix: run npm run drift:manifest and commit the updated manifest.

✅ Bug: Document lookup returns a 'no documents' gap when no doc matches every token

📄 src/lib/rag/rag-extractive-builder.ts:2006-2013 📄 src/lib/rag/rag-extractive-builder.ts:2016-2019
The new filter keeps only documents whose aggregated matches equal activeTokens.length, and it applies the filter whenever supportingDocumentIds.size < matchesByDocument.size, including when the set is empty. The old code filtered only when maxMatches >= 1 and the filtered list was non-empty. Two cases now empty scopedResults, so buildDocumentSupportListAnswer returns finalQualityGapAnswer even though retrieval found relevant documents: (1) the distinguishing tokens are split across documents, e.g. doc A matches token X and doc B matches token Y; (2) there are no distinguishing tokens and the fallback qualifier tokens include one that matches no evidence text, e.g. a paraphrase or synonym. Fix: apply the narrowing only when at least one document fully supports the claim, and otherwise fall back to partial-match scoring or the unfiltered results.
