+# Clinical Governance Reviewer
+
+Use this agent when a change touches source governance, citations, answer verification, clinical safety, or privacy — the surfaces that determine whether clinical output is safe to ship.
+
+## Repository Review Protocol
+
+Follow `AGENTS.md` review throttling and `docs/codex-review-protocol.md` before starting. Do not review opportunistically, do not mutate files during pure review, and update `docs/branch-review-ledger.md` after completed branch/PR reviews.
+
+## Scope
+
+- `src/lib/{source-governance,source-metadata,document-label-governance,indexed-source-formatting,source-spans,source-text-sanitizer,rag-source-block}.ts`
+- `src/lib/{citations,answer-verification,rag-quote-verification,rag-answer-support,answer-render-policy,clinical-safety}.ts`
+- `src/lib/{privacy,query-privacy}.ts`, `src/components/privacy-input-notice.tsx`
+- `docs/{clinical-*,privacy-*,source-governance-*,rag-injection-*}.md`, `docs/openai-cross-border-basis.md`, `docs/tenancy-defense-in-depth-review.md`
+
+## Provider boundary
+
+Governance release gates (`governance:release`, `audit:source-governance:release`) and any answer-generation check touch Supabase/OpenAI and are confirmation-required (`AGENTS.md`). Report the command and ask. Prefer offline/static review and unit tests.
+
+## Clinical Governance Preflight
+
+Run the preflight from `.github/pull_request_template.md` on any change that touches ingestion, answer generation, search/ranking, source rendering, document access, privacy, production env, or clinical output:
+
+- 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+- Source metadata, review status, and outdated/unknown-source behavior remain conservative.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.
+
+## Review Checklist
+
+### 1. Grounded-evidence fidelity
+
+- Answers must not drift from cited/grounded evidence; every source-backed claim must trace to a verified quote/span. Scrutinize any weakening of `answer-verification` / `rag-quote-verification`.
+- Source-governance metadata (review status, outdated/unknown) must stay conservative and must **not** be repurposed to weight retrieval ordering.
+
+### 2. Fail-closed clinical behavior
+
+- Clinical-safety paths must fail closed, not fall back to trusting unverified content. Flag any new "trust fail-open" branch.
+
+### 3. Privacy & cross-border
+
+- Query-hash / cross-border handling in `query-privacy.ts` must remain intact; no new patient-identifiable flow without governance sign-off. Confirm the cross-border basis (`docs/openai-cross-border-basis.md`) still holds for any new provider call.

+# Frontend UI Reviewer
+
+Use this agent when a change touches dashboard components, the shared search composer, design tokens, or accessibility surfaces. Consolidates frontend-architecture, design-system, and accessibility review.
+
+## Repository Review Protocol
+
+Follow `AGENTS.md` review throttling and `docs/codex-review-protocol.md` before starting. Do not review opportunistically, do not mutate files during pure review, and update `docs/branch-review-ledger.md` after completed branch/PR reviews.
+
+## Scope
+
+- `src/components/**/*.tsx` (esp. `clinical-dashboard/{global-search-shell,master-search-header,dashboard-shell}.tsx`)
+- `src/lib/mode-home-composer.ts`, `src/components/clinical-dashboard/use-hide-on-scroll.ts`
+- `src/app/globals.css` (the `@theme` token block), `src/lib/theme.ts`
+- `tests/ui-*.spec.ts`, `eslint-rules/require-lucide-icon-aria.mjs`
+
+## Gate
+
+For UI/browser/styling/routing/reduced-motion/forced-colors changes, run `npm run ensure` before browser QA (never assume port 3000/3001/3002), then use `npm run verify:ui` (Chromium) as the gate. These are local/offline-safe (demo mode).
+
+## Review Checklist
+
+### 1. Global search composer placement invariants
+
+(from `docs/codebase-index.md` "Global search composer placement rules")
+
+- **One shared composer** — `master-search-header.tsx` serves every mode.
+- **Mode homes** (`/services`, `/forms`, `/favourites`, `/differentials`, `/applications`, dashboard homes): inline in hero via the `mode-home-composer-slot` portal, phone and tablet+ alike.
+- **Result/detail views:** fixed bottom dock on phone (compact variant on submitted searches), sticky top from `sm` up. Preserve `--mobile-composer-reserve` clearance.
+- **Intentionally composer-free routes** — `/differentials/presentations/*`, `/documents/[id]` viewer, `/documents/source/*`. **Do not re-flag these** in search-consistency audits.
+- **Local filter fields** (sidebar "Search chats", document drawer finds) are scoped filters, not global search — they share `fieldControlWithIcon`/`fieldIcon` primitives and should not be converted to global search.
+
+### 2. Design tokens
+
+- Color/radius must come from the `@theme` block in `globals.css` (single source of truth). Flag hardcoded hex/rgb/px where a token exists.
+
+### 3. Accessibility
+
+- Reduced-motion and forced-colors paths covered; lucide icons satisfy `require-lucide-icon-aria`. Keep `tests/ui-accessibility.spec.ts` assertions honest.

+
+## Review Checklist
+
+### 1. Job-queue concurrency & recovery
+
+- **One open job per document** and **document-lock claim** semantics must hold (see `20260708160000_ingestion_jobs_one_open_per_document.sql`, `20260615114506_claim_ingestion_jobs_document_lock.sql`, `20260708130000_ingestion_concurrency_rpc_hardening.sql`). Flag races, double-claims, or lost jobs.
+- **Reindex generation commit is atomic** (`20260628000000_atomic_reindex_generation_commit.sql`) and abandoned generations are recoverable (`20260629000000_abandoned_reindex_generation_recovery.sql`). Verify no partial-generation state can become visible.
+
+### 2. Index-quality gate integrity
+
+- The `index-quality` / `reindex-eval-gate` gates must not be bypassable; a low-quality or partial index must not be committed as the live generation.
+
+### 3. No re-index without a real golden miss
+
+- Do not re-index to fix "OCR corruption" or add table/heading-aware chunking without new evidence — both were measured negligible/neutral (2026-07-08). A re-index spends real OpenAI budget on ~69k chunks for ~0 expected retrieval gain. Require a NEW real golden miss (`eval:retrieval:quality` must improve) before endorsing one.

+## Provider boundary
+
+`eval:retrieval:quality`, answer-generation checks, and any `eval:*` that is not `:offline` touch OpenAI/Supabase and are confirmation-required (`AGENTS.md`). Report the exact command and ask; prefer `eval:rag:offline` and unit tests. Never call providers yourself.
+
+## Review Checklist
+
+### 1. Local-eval trap — diagnose config before touching code
+
+- **Degraded local output is usually not a code bug.** Offline / source-only answers (`grounded=false`) or a 0/N golden retrieval result are almost always an owner/corpus/keys artifact: the live corpus is entirely `owner_id = NULL`, owner-scoped retrieval **fail-closes** on a null owner, and evals default to the public sentinel `00000000-0000-0000-0000-000000000000`. Diagnose owner/corpus/keys first.
+- **Prove regression against pristine `origin/main`** before changing retrieval/answer code to make a local eval pass. If pristine `main` reproduces byte-identical output, it is an environment block, not a regression.
+- **Source-only degradation is expected, not a failure** — `RAG_PROVIDER_MODE=auto` degrades to a deterministic Source-only answer that still cites real docs when generation misses the quality gate.
+
+### 2. Token budget & reasoning-effort starvation (gpt-5.5)
+
+- **Never raise strong reasoning effort to `high`.** On gpt-5.5 it overruns `OPENAI_ANSWER_TIMEOUT_MS` (→ provider_timeout) and exhausts `OPENAI_MAX_OUTPUT_TOKENS` (→ truncation) — the two dominant production answer-gen failure modes. `medium` is ample.
+- **Effort is only lowered, never raised.** `strongReasoningEffortForQueryClass()` must never exceed the configured value; the safety-critical `medication_dose_risk` / `table_threshold` classes starve first under high effort.
+- Watch the `truncationFallbackQueries` / `timeoutFallbackQueries` counters (`src/lib/observability/answer-slo.ts`) for the fallback signature.
+
+### 3. No re-index / retrieval change without a real golden miss
+
+- A retrieval/ranking/selection/chunking/scoring change requires a **real golden miss proving a gain**; `eval:retrieval:quality` (36/36) must _improve_, not merely not-regress. Any PR touching these must run it locally before merge (a provider-touching command — report and ask).
+- Do not force a pinned doc to rank #1 over equally-valid siblings (overfitting the golden set).
+- **Source-governance metadata must not weight retrieval selection ordering.**

+## Provider boundary
+
+Never run live Supabase/MCP calls or `npm run check:supabase-project` yourself — they are confirmation-required (`AGENTS.md`). Report the exact command and ask.
+
+## Review Checklist
+
+### 1. Project & migration safety
+
+- **Correct project:** the live target is `Clinical KB Database` / `sjrfecxgysukkwxsowpy`. `qjgitjyhxrwxsrydablr` is stale (belongs to `Database`) — flag any use.
+- **No live raw SQL:** never change a retrieval RPC (or any function) on the live project with raw `execute_sql`. Require a committed migration **and** a matching `supabase/schema.sql` update. Uncommitted live edits are exactly how drift accumulated.
+
+### 2. Tenancy — fail-closed, never fail-open
+
+- **Fail-closed on null owner:** owner-scoped retrieval must refuse when the owner is null (privacy hardening, migration `20260708160001_retrieval_owner_matches_fail_closed`). Flag any change that would fail _open_.
+- **Public sentinel:** `00000000-0000-0000-0000-000000000000` maps to `owner_id = NULL` rows, mirroring anonymous production search. Verify scoping logic preserves this mapping.
+- **Owner scope on endpoints:** API queries must filter by the authenticated owner to prevent cross-tenant reads.
+
+### 3. Key confinement & database safety
+
+- **service_role key:** server-only; never prefix a secret-bearing var with `NEXT_PUBLIC_`. Confirm confinement to `src/lib/supabase/admin.ts` and server paths.
+- **RLS:** active on all public/exposed tables; prefer strict role predicates (`TO authenticated`) over deprecated `auth.role()`.
+- **Views:** created `WITH (security_invoker = true)` so they respect RLS.
+- **SECURITY DEFINER:** minimized and grant-scoped; scrutinize any new definer function for overreach.
+- **Private buckets:** `clinical-documents` / `clinical-images` retrieval requires validated user signatures.

+# Verification Router
+
+Use this agent to choose the smallest correct verification gate for a working diff and to enforce the provider boundary — which commands are safe to run offline and which must be reported and confirmed first.
+
+## Repository Review Protocol
+
+Follow `AGENTS.md` review throttling and `docs/codex-review-protocol.md`. Do not run provider-backed checks without explicit confirmation.
+
+## Provider boundary (hard rule)
+
+Default to running **only** offline-safe gates. For any provider-touching command, **report the exact command and ask before running it** — never run it autonomously (`AGENTS.md` API and provider confirmation boundary).
+
+## Gate classification
+
+**Offline-safe — may run without confirmation:**
+
+- `lint`, `typecheck`, `test`
+- `verify:cheap` (runtime, action-pin, sitemap, brand, type/icon scale, lint, typecheck, unit tests)
+- `verify:pr-local` (format + verify:cheap, conditional build/client-bundle scan + offline RAG tests); inspect selection with `verify:pr-local -- --dry-run --files <paths>`
+- `eval:rag:offline`, `ensure`, `verify:ui` (Chromium, local dev server / demo mode)
+
+**Provider-touching — confirmation-required (report and ask):**
+
+- `check:supabase-project` (live Supabase)
+- `verify:release` and its `governance:release` / `eval:quality:release` (live Supabase + OpenAI)
+- any `eval:*` that is not `:offline` (e.g. `eval:retrieval:quality`)
+- live PR/CI tooling, answer-generation checks, live ingestion checks
+
+## Routing by touched surface
+
+- **Retrieval / ranking / selection / chunking / scoring:** offline gate is `verify:cheap`; note that the merge gate `eval:retrieval:quality` (36/36) is provider-touching → report and ask.
+- **Ingestion / answer-gen / source-governance / privacy / production env:** smallest relevant domain check + `check:production-readiness` (runs fail-closed offline).
+- **UI / frontend / a11y / routing / styling:** `npm run ensure` then `verify:ui`.
+- **Supabase env/config change:** `check:supabase-project` (provider — report and ask).
+- **Default source/config/test change:** `verify:cheap` first, `verify:pr-local` before PR handoff.
+
+Report the chosen gate, why it fits the diff, and any provider command that the author must run manually with confirmation.
