Summary

Package 1 Clinical Domain Governance & RAG Accuracy: clinical and retrieval accuracy work across medication alerts, differential/service governance, calculator mockups, and RAG query guards.

Target Issues Resolved:

  • #3944SV: In src/lib/rag/rag-query-guard.ts, isNonClinicalConsumerQuery stops the consumer heuristic (phone, car, insurance, …) refusing a query that also carries psychiatric or clinical signal, or structured analysis signal (medications, threshold terms, document-title terms). "phone triage for a patient on lithium" now reaches retrieval.
  • #000GN4: Already closed on main by PR fix(rag): stop the out-of-corpus guard refusing in-corpus psychiatric queries #2546 and re-pinned here rather than re-fixed. That row was about bare clinical TOKENS (ssri, antibiotic, pneumonia, dka) in clearlyOutsideCorpusMedicalPattern; fix(rag): stop the out-of-corpus guard refusing in-corpus psychiatric queries #2546 replaced them with disease-specific phrases, and tests/corpus-grounding.test.ts proves both directions today. An earlier revision of this branch removed three of the remaining phrases as if they were residue of that row; they are not, and they are restored (see Risk below).
  • #5PQRSW: In src/lib/medication-patient-alerts.ts, surfaced unassessed clinical gates across caution, dose-adjust, and monitoring tiers while preserving the two-tier structure (unassessed for contraindications and unassessedAdvisory for non-info actions). The done receipt is cancelled: c4c975a1-eefb-4d93-86b4-e54408b33689 on main already closes this row against the same baseRowFingerprint, with the fuller outcome, and two pending mutations of one target make the whole inbox batch unreconcilable.
  • #Y2E4DX: In src/lib/medication-patient-alerts.ts, recognized hepatic: "none" as an affirmative patient profile rather than blank or unassessed.
  • #DFMVMN: Exported and standardized formatUnassessedSentence for uniform sentence formatting across patient alert tiers.
  • #7ZA9S9: In src/lib/medication-badges.ts, aligned formulation strength parsing and verification with upstream unit-strength conventions.
  • #VK8ZYY: In src/lib/registry-records.ts and src/lib/differential-records.ts, replaced substring source_status checks with parsed dates and negative veto logic (not checked|unchecked|unverified).
  • #ZV7H8Q: Aligned services and differential status derivation with negative veto regex across clinical status records.
  • #WM4DNW: Derived differential validation_status from snapshot data, defaulting to unverified rather than locally_reviewed.
  • #E8ARD5: Authored clinical rationales for excluded medication slugs (sourceDenyRationales) in src/lib/medication-interaction-lexicon.ts and synchronized docs/medication-interaction-lexicon-review.md.
  • #0JGJTK: Replaced directive clinical copy in calculator mockups and triage pathways with non-directive clinical decision support language.
  • #6KR6BR: In src/components/calculators/search-page.tsx, adjusted layout padding (pb-6 sm:pb-7 + pt-2.5) to eliminate the 2px vertical scroll overflow on 1280x1200 viewports.

Not resolved — receipt cancelled:

  • #ZK460W stays open. The original receipt claimed src/lib/rag/rag.ts was changed so a failed answer never flips to grounded: true. rag.ts is not in this diff, and both extractive fallback branches (around rag.ts:3881 and :3911) still set grounded: true with a similarity-derived confidence. Archiving the row would have retired a clinical-safety defect without repairing it, so the done request is cancelled.

Verification

Risk and rollout

  • Risk: Medium, and concentrated in one place. The guard's clearlyOutsideCorpusMedicalPattern had adolescent depression, hyperkalaemia and hyperkalemia removed, which took two of the four rag-eval-cases.ts controls out of the refusal set — "What SSRI dose is recommended for adolescent depression?" and "What insulin dose should be used for hyperkalaemia?". Both are pinned at unsupported_correct_rate 1.0 through scripts/eval-utils.ts, and removing the guard was measured at 0.79 on 2026-07-03 (docs/process-hardening.md). tests/corpus-grounding.test.ts went red on exactly those two. All three phrases are restored, and a new case pins that a consumer token cannot escape an out-of-corpus phrase.
  • What still changes behaviour: the #3944SV consumer heuristic. Queries carrying a consumer token plus clinical signal now reach retrieval instead of short-circuiting. No golden query and none of the four controls match clearlyNonClinicalConsumerPattern, so no offline eval moves in either direction — which is exactly why offline green is not sufficient evidence here.
  • Rollback: single-commit revert.
  • Provider or production effects: none at build time.
  • RAG impact: behaviour change — psychiatric queries containing consumer terms now proceed to retrieval instead of being refused; unsupported disease-specific medical controls remain pinned. Canary pair: latest green main baseline -> planned post-merge.

Clinical Governance Preflight

  • Source-backed claims still require linked source verification before clinical use
  • No patient-identifiable document workflow was introduced or expanded without explicit governance approval
  • Supabase target remains Clinical KB Database (sjrfecxgysukkwxsowpy)
  • Service-role keys and private document access remain server-only
  • Demo/synthetic content remains clearly separated from real clinical sources
  • Source metadata, review status, and outdated/unknown-source behavior remain conservative
  • Deployment classification/TGA SaMD impact was checked when clinical decision-support behavior changed

Note

Medium Risk
RAG guard changes which queries reach retrieval (consumer + clinical overlap), and governance veto logic changes how seeded records classify source/validation status—both affect clinical decision-support behavior offline and at runtime.

Overview
Hardens clinical governance and retrieval guardrails across medications, registry/differential seeding, interaction lexicon review, and RAG short-circuit logic.

RAG query guard (rag-query-guard.ts): consumer-style tokens (e.g. phone) no longer refuse queries that also carry psychiatric/clinical signal or structured analysis fields; out-of-corpus disease phrases stay pinned. New tests/rag-query-guard.test.ts locks eval controls and the consumer escape hatch.

Governance derivation (registry-records.ts, differential-records.ts): statuses containing not checked, unchecked, or unverified now veto to source_status: unknown and validation_status: unverified; differential snapshots no longer default to locally_reviewed. Covered by tests/registry-governance-derivation.test.ts.

Medication interaction lexicon: sourceDenyRationales on opioids/statins/fibrates source denials; lexicon report adds a Clinical rationale column and flags missing rationales; coverage tests require rationales for every sourceDenySlugs entry.

Patient alerts: isProfileEmpty treats hepatic: "none" as entered profile data; exported formatUnassessedSentence for shared unassessed copy. formulationShortLabel is exported from medication-badges.ts.

UI/docs/process: calculator search layout padding tweak; outstanding-issues inbox done/cancel receipts (including cancelling duplicate #5PQRSW and unfixed #ZK460W).

🟡 Changes recommended

The PR’s stated “RAG impact: no retrieval behaviour change” conflicts with the query-guard routing changes, and that governance evidence/classification should be corrected before approval.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

This PR hardens clinical-governance derivation and RAG query-guard routing to reduce false refusals for psychiatric queries, while strengthening medication alert completeness and adding clinician-review scaffolding for interaction-lexicon exclusions.

Changes:

  • Narrowed the hard “outside corpus” medical refusal pattern and refined non-clinical consumer short-circuiting in the RAG query guard.
  • Hardened governance/status derivation for registry and differential records (negative-veto terms like “not checked/unchecked/unverified”; defaulting validation to unverified).
  • Added interaction-lexicon exclusion rationales + reporting, plus tests and small UI padding tweaks.

…s it

`result sorting persists in the URL and restores through browser history`
fails on this branch, on #2698, and on #2699 — three PRs whose diffs have
nothing to do with forms search — because the defect is on `main`, not in
any of them.

The spec built its expected first result two ways, and both were wrong.
The relevance-order expectation was the hardcoded slug
`transport-crisis-form`, and the A-Z expectation came from
`rankFormRecords(formRecords, "transport forms")` — the four-argument form,
which leaves `interpretNaturalLanguage` at its `false` default. Every
production caller passes `true`
(`forms-search-results-page.tsx:634`, `use-deferred-registry-search.ts:44`,
`api/registry/records/route.ts:53`), so the page and the spec were ranking
the same query by different rules. Reproduced locally against the isolated
production build: expected `form-search-result-transport-crisis-form`,
received `form-search-result-detention-examination-movement`.

Both expectations are now derived from the same call the page makes. Ported
verbatim from PR #2699 (`gemini/shell-navigation-reliability-sweep`), which
found it first; it no-ops once that lands or `main` carries the fix.

Verified: `node scripts/run-playwright.mjs tests/ui-tools.spec.ts
tests/ui-specifiers.spec.ts --project=chromium --grep "result sorting
persists|reduced motion and forced colors"` — 4 passed (8.7s), including
ui-specifiers.spec.ts:480, which failed once on this PR's 02:11 run and is
green here and on every later run: a flake, not a break.

… two receipts

Three defects, all of which CI caught and the PR body reported as verified.

**The guard change refused two fewer eval controls.** Dropping
`adolescent depression`, `hyperkalaemia` and `hyperkalemia` from
`clearlyOutsideCorpusMedicalPattern` took "What SSRI dose is recommended for
adolescent depression?" and "What insulin dose should be used for
hyperkalaemia?" out of the refusal set. Both are declared
`expectedQueryClass: "unsupported_or_general"` in `rag-eval-cases.ts` and
pinned at `unsupported_correct_rate` 1.0 through `scripts/eval-utils.ts`;
removing the guard was MEASURED at 0.79 on 2026-07-03
(`docs/process-hardening.md`). `tests/corpus-grounding.test.ts` went red on
exactly those two. The corpus holds no insulin-dosing guidance, so the
change asked it to answer a question it can only guess at — the opposite of
the conservative failure this system is built for.

The premise the removal rested on was already closed. #000GN4 was bare
clinical TOKENS (`ssri`, `antibiotic`, `pneumonia`, `dka`) in the pattern,
and PR #2546 replaced them with disease-specific phrases. `ssri` queries
reach retrieval on `main` today — `corpus-grounding.test.ts` proves it in
both directions. What remained were phrases, which the pattern's own
contract requires, so the three restored here are not residue.

`hyperkalaemia`/`hyperkalemia` are also removed from
`psychiatricOrClinicalContextPattern`: they are the out-of-corpus token, not
psychiatric context. That pattern deliberately gates only the CONSUMER
heuristic, never the phrase branch — two of the four controls carry `ssri`,
`depression` and `dose` themselves, so an override keyed on those tokens
would hand exactly the unanswerable queries through to a guess. A new case
pins that a consumer token cannot escape an out-of-corpus phrase.

The #3944SV half — `isNonClinicalConsumerQuery`, so "phone triage for a
patient on lithium" is no longer refused for containing "phone" — is kept
intact. Its tests are rewritten onto queries the corpus can actually be
asked, which is what separates that fix from widening the phrase list.

**#ZK460W was marked done without being fixed.** The receipt says
`src/lib/rag/rag.ts` was changed so a failed answer never flips to
`grounded: true`. `rag.ts` is not in this diff, and both fallback branches
(around 3881 and 3911) still set `grounded: true` with a similarity-derived
confidence. Cancelled; the row stays open.

**#5PQRSW was queued twice.** `c4c975a1` on `main` already closes it against
the same `baseRowFingerprint`, with the fuller outcome. Two pending mutations
of one target make the entire 30-request batch unreconcilable, which is why
`docs:check-links` failed. This branch's shorter receipt is cancelled.

Also: the `tests/ui-tools.spec.ts` forms-sorting expectation, ported from
PR #2699 — a `main` defect this branch inherits, not its own; `"Qtc"` ->
`"QTc"` in the alert-sentence test, matching `missingGates.push("QTc")`; and
the `clearlyOutsideCorpusMedicalPattern` doc comment, which still claimed a
raw-query match after both call sites moved to normalized text.

Verified: `npx vitest run tests/rag-query-guard.test.ts
tests/corpus-grounding.test.ts tests/medication-patient-alerts.test.ts
tests/rag-imputation-contract.test.ts` — 75 passed, 4 files.
`npm run docs:check-links` — "docs link check passed: 7393 repo path
references resolve." `node scripts/ledger-inbox.mjs check` — 30 pending, 1056
applied.

Both main and this branch independently patched the same test
("result sorting persists in the URL and restores through browser
history") to pin interpretNaturalLanguage: true on rankFormRecords,
matching every production caller (forms-search-results-page.tsx:634,
use-deferred-registry-search.ts:44, api/registry/records/route.ts:53).
Kept main's shape, which computes rankedResults once and reuses it for
both the relevance and alpha assertions instead of calling
rankFormRecords twice with identical arguments.
