P1: Prescribing `useMedicationCatalog(query)` refetches the full ~2.5–2.9 MB medication catalogue on every keystroke without debounce, abort, or `fields=index` (~25× larger than index). P2: differentials catalogue + evidence `/api/search` lack abort/debounce; universal typeahead `tookMs` dominated by empty live documents domain (~130–340 ms); cross-namespace mode switches remount the search shell; Answer submit returns 503 `rate_limit_unavailable` when durable limiter is down (fail-closed). Mode HTML load medians ~40–75 ms; typeahead wall ~160–180 ms (`ssri`) / ~350–400 ms (`agitation im lorazepam`) + 250 ms client debounce; catalogue submits (differentials) ~45 ms; document `/api/search` demo-degraded ~230–430 ms. Highest residual live risk: cold hybrid RPC tails (docs #25), not re-measured with soak/eval. | `npm run ensure` → http://localhost:4461; `/api/local-project-id` Clinical KB; paced universal typeahead across 13 modes × 2 queries (Server-Timing); `/api/search` + `/api/medications` (+`fields=index`) + differentials APIs + registry payload sizes; NDJSON vs JSON first-byte; browser walkthrough of 13 mode homes; static review of ClinicalDashboard / universal-search / medication+differential hooks. No OpenAI generation, no `eval:retrieval:latency`, no soak, no hosted CI. Environment had Supabase secrets so universal ran live (`publicAccess`); `/api/search` degraded to demo (`supabase_api_key_configuration_unavailable`). |
 | 2026-07-24 | `codex/safety-plan-no-patient-data-contract` | `b94987c94537f3114a3429848fa908bdecd1d80a` | Safety Plan Generator identifier, local-state, copy, print, privacy-notice and PIA contract | APPROVE. No P0-P2 finding. The patient name/initials field is removed; the builder now asks for identifier-free minimum content, retains working state only in the mounted React component, and makes clipboard/print/PDF export an explicit handling boundary. The PIA and product privacy copy distinguish this local-only tool from provider-backed questions. Highest residual risk is outside Clinical KB: users must handle exported copies under an approved clinical-record process, which the UI now states at the export controls. | Privacy/component DOM 3/3 plus updated privacy-copy 2/2; focused Chromium copy/print/no-fetch-or-XHR 1/1; `verify:cheap` passed all 21 gates, 366 files and 3,245 tests with 1 skip; production-readiness READY using the existing canonical environment without a provider call; production build and client-bundle secret scan passed; offline RAG fixture/manifest 36 cases/21 suites passed. `verify:pr-local` passed runtime, formatting, lint and typecheck, then stopped on the unrelated load-sensitive `reconciliation-preflight` 30-second timeout; that test passed 5/5 isolated and the preceding full suite passed, so the unchanged five-minute gate was not retried. No Supabase, OpenAI, Railway, live RAG, production data or deployment action ran. |
 | 2026-07-24 | PR #1114 / `codex/universal-ledger-main-followup-20260724` | `eedbe594a89eaa0aad8a517ee8808b089cb5ff57` + reviewed working diff | Streamlined-sidebar handoff in the merged universal ledger | APPROVE. PRs #1112, #1116, and #1117 landed the universal-ledger baseline, two preserved UI tasks, and credential/hook hardening; this follow-up preserves that current-main schema and adds only the still-missing sidebar delivery as collision-free `#066`. The queue remains gap-free and every recommended ID has one open row. Sidebar implementation stays recoverable from remote branch `origin/codex/sidebar-test-fix-20260723` at full commit `cd54e68fbf7b07b5dffe3220e36af2caa528da54` until its local/browser/build/hosted merge proof is complete. | Focused sidebar/favourites tests previously passed 18/18 on the recorded implementation commit; this ledger follow-up passed Prettier, remote-ref recovery, 36-row contiguous-order/46-open-ID/next-ID invariants, and `git diff --check`. The broader reconciled precursor passed `verify:cheap` (365 files, 3,242 passed/1 skipped); fresh exact-head hosted CI is required on PR #1114. No OpenAI, Supabase, Railway, deployment, live-app, credential, or production-data action ran. |
 | 2026-07-24 | `codex/universal-ledger-main-final` | `527988c2ccabc98b4d0673d33360c971df65fa0e` + reviewed working diff | Current-main universal-ledger reconciliation after PR #1106 superseded PR #1109 | READY. Kept PR #1106's current-main ledger and IDs, carried forward only non-duplicate recommended work from the superseded branch, and fixed the confirmed SessionStart empty-open defect. Every active recommendation now has a durable open ID; exposed-GitHub-token containment is the first A1 item; the Safety Plan privacy contract, absent-relevance fail-closed rule, stranded-upload recovery, threshold-conflict design, catalogue-toolbar convergence, and Current Clinical Work brief are retained without duplicating #1106's legal/config/release/staging/seed packages. Resolved #014/#034 claims stay archived, and PR #1110's scheduled-diagnostics priority remains intact. Highest residual risk is manual queue/open-table drift. | Empty-open fixture and real-ledger Bash execution passed; 33 contiguous recommendations reference tracked open IDs; 43 open items; no duplicate queued IDs; `docs:check-links`, `docs:check-index`, `docs:check-scripts`, `check:skills`, Prettier, and `git diff --check` passed. No OpenAI, Supabase, Railway, production, deployment, live-app, or credential action. |

Subject: [PATCH 02/16] fix: resolve search performance findings across modes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Debounce/abort prescribing medication catalogue fetches with fields=index,
harden differentials catalogue and evidence search cancellation, soft-timeout
universal documents typeahead (750ms), keep GlobalSearchShell mounted via a
shared (search-app) layout, and allow Answer rate-limit in-memory fallback in
non-production when the durable RPC is unavailable.

RAG impact: no retrieval behaviour change — typeahead documents domain timeout
only; ranking formulas and full /api/search path unchanged.

+| 2026-07-24 | `cursor/search-performance-review-4ee9` / PR #1134 | pending-fix-commit | Search performance findings remediation (prescribing, differentials, typeahead docs timeout, shared shell, answer rate-limit fallback) | FIXED. P1 prescribing catalogue now debounces (250 ms), aborts in-flight fetches, and uses `fields=index`. Differentials catalogue + evidence search abort/debounce. Universal documents typeahead timeout 6 s→750 ms (RAG impact: no retrieval behaviour change — typeahead timeout only). Shared `(search-app)` layout keeps GlobalSearchShell mounted across mode homes. Answer rate-limit fails closed only in production; development uses in-memory fallback when durable RPC is unavailable. | Focused Vitest 362 via test:focused; api-rate-limit/search-shell/universal/route/site-map suites green; `npm run ensure` smoke 200 on mode homes; `/api/answer/stream` 200 after fallback. No OpenAI spend beyond local answer stream smoke; no live eval/soak. |
 | 2026-07-24 | `main` | `6ceaaff50712e10e857bf9a5a7ec88b530bf7b35` | Search performance across modes (load + typeahead + submit; local ensure) | CHANGES REQUESTED / findings. No P0. P1: Prescribing `useMedicationCatalog(query)` refetches the full ~2.5–2.9 MB medication catalogue on every keystroke without debounce, abort, or `fields=index` (~25× larger than index). P2: differentials catalogue + evidence `/api/search` lack abort/debounce; universal typeahead `tookMs` dominated by empty live documents domain (~130–340 ms); cross-namespace mode switches remount the search shell; Answer submit returns 503 `rate_limit_unavailable` when durable limiter is down (fail-closed). Mode HTML load medians ~40–75 ms; typeahead wall ~160–180 ms (`ssri`) / ~350–400 ms (`agitation im lorazepam`) + 250 ms client debounce; catalogue submits (differentials) ~45 ms; document `/api/search` demo-degraded ~230–430 ms. Highest residual live risk: cold hybrid RPC tails (docs #25), not re-measured with soak/eval. | `npm run ensure` → http://localhost:4461; `/api/local-project-id` Clinical KB; paced universal typeahead across 13 modes × 2 queries (Server-Timing); `/api/search` + `/api/medications` (+`fields=index`) + differentials APIs + registry payload sizes; NDJSON vs JSON first-byte; browser walkthrough of 13 mode homes; static review of ClinicalDashboard / universal-search / medication+differential hooks. No OpenAI generation, no `eval:retrieval:latency`, no soak, no hosted CI. Environment had Supabase secrets so universal ran live (`publicAccess`); `/api/search` degraded to demo (`supabase_api_key_configuration_unavailable`). |
 | 2026-07-24 | `codex/safety-plan-no-patient-data-contract` | `b94987c94537f3114a3429848fa908bdecd1d80a` | Safety Plan Generator identifier, local-state, copy, print, privacy-notice and PIA contract | APPROVE. No P0-P2 finding. The patient name/initials field is removed; the builder now asks for identifier-free minimum content, retains working state only in the mounted React component, and makes clipboard/print/PDF export an explicit handling boundary. The PIA and product privacy copy distinguish this local-only tool from provider-backed questions. Highest residual risk is outside Clinical KB: users must handle exported copies under an approved clinical-record process, which the UI now states at the export controls. | Privacy/component DOM 3/3 plus updated privacy-copy 2/2; focused Chromium copy/print/no-fetch-or-XHR 1/1; `verify:cheap` passed all 21 gates, 366 files and 3,245 tests with 1 skip; production-readiness READY using the existing canonical environment without a provider call; production build and client-bundle secret scan passed; offline RAG fixture/manifest 36 cases/21 suites passed. `verify:pr-local` passed runtime, formatting, lint and typecheck, then stopped on the unrelated load-sensitive `reconciliation-preflight` 30-second timeout; that test passed 5/5 isolated and the preceding full suite passed, so the unchanged five-minute gate was not retried. No Supabase, OpenAI, Railway, live RAG, production data or deployment action ran. |
 | 2026-07-24 | PR #1114 / `codex/universal-ledger-main-followup-20260724` | `eedbe594a89eaa0aad8a517ee8808b089cb5ff57` + reviewed working diff | Streamlined-sidebar handoff in the merged universal ledger | APPROVE. PRs #1112, #1116, and #1117 landed the universal-ledger baseline, two preserved UI tasks, and credential/hook hardening; this follow-up preserves that current-main schema and adds only the still-missing sidebar delivery as collision-free `#066`. The queue remains gap-free and every recommended ID has one open row. Sidebar implementation stays recoverable from remote branch `origin/codex/sidebar-test-fix-20260723` at full commit `cd54e68fbf7b07b5dffe3220e36af2caa528da54` until its local/browser/build/hosted merge proof is complete. | Focused sidebar/favourites tests previously passed 18/18 on the recorded implementation commit; this ledger follow-up passed Prettier, remote-ref recovery, 36-row contiguous-order/46-open-ID/next-ID invariants, and `git diff --check`. The broader reconciled precursor passed `verify:cheap` (365 files, 3,242 passed/1 skipped); fresh exact-head hosted CI is required on PR #1114. No OpenAI, Supabase, Railway, deployment, live-app, credential, or production-data action ran. |

 | 2026-07-24 | `main` | `6ceaaff50712e10e857bf9a5a7ec88b530bf7b35` | Search performance across modes (load + typeahead + submit; local ensure) | CHANGES REQUESTED / findings. No P0. P1: Prescribing `useMedicationCatalog(query)` refetches the full ~2.5–2.9 MB medication catalogue on every keystroke without debounce, abort, or `fields=index` (~25× larger than index). P2: differentials catalogue + evidence `/api/search` lack abort/debounce; universal typeahead `tookMs` dominated by empty live documents domain (~130–340 ms); cross-namespace mode switches remount the search shell; Answer submit returns 503 `rate_limit_unavailable` when durable limiter is down (fail-closed). Mode HTML load medians ~40–75 ms; typeahead wall ~160–180 ms (`ssri`) / ~350–400 ms (`agitation im lorazepam`) + 250 ms client debounce; catalogue submits (differentials) ~45 ms; document `/api/search` demo-degraded ~230–430 ms. Highest residual live risk: cold hybrid RPC tails (docs #25), not re-measured with soak/eval. | `npm run ensure` → http://localhost:4461; `/api/local-project-id` Clinical KB; paced universal typeahead across 13 modes × 2 queries (Server-Timing); `/api/search` + `/api/medications` (+`fields=index`) + differentials APIs + registry payload sizes; NDJSON vs JSON first-byte; browser walkthrough of 13 mode homes; static review of ClinicalDashboard / universal-search / medication+differential hooks. No OpenAI generation, no `eval:retrieval:latency`, no soak, no hosted CI. Environment had Supabase secrets so universal ran live (`publicAccess`); `/api/search` degraded to demo (`supabase_api_key_configuration_unavailable`). |
 | 2026-07-24 | `codex/safety-plan-no-patient-data-contract` | `b94987c94537f3114a3429848fa908bdecd1d80a` | Safety Plan Generator identifier, local-state, copy, print, privacy-notice and PIA contract | APPROVE. No P0-P2 finding. The patient name/initials field is removed; the builder now asks for identifier-free minimum content, retains working state only in the mounted React component, and makes clipboard/print/PDF export an explicit handling boundary. The PIA and product privacy copy distinguish this local-only tool from provider-backed questions. Highest residual risk is outside Clinical KB: users must handle exported copies under an approved clinical-record process, which the UI now states at the export controls. | Privacy/component DOM 3/3 plus updated privacy-copy 2/2; focused Chromium copy/print/no-fetch-or-XHR 1/1; `verify:cheap` passed all 21 gates, 366 files and 3,245 tests with 1 skip; production-readiness READY using the existing canonical environment without a provider call; production build and client-bundle secret scan passed; offline RAG fixture/manifest 36 cases/21 suites passed. `verify:pr-local` passed runtime, formatting, lint and typecheck, then stopped on the unrelated load-sensitive `reconciliation-preflight` 30-second timeout; that test passed 5/5 isolated and the preceding full suite passed, so the unchanged five-minute gate was not retried. No Supabase, OpenAI, Railway, live RAG, production data or deployment action ran. |
 | 2026-07-24 | PR #1114 / `codex/universal-ledger-main-followup-20260724` | `eedbe594a89eaa0aad8a517ee8808b089cb5ff57` + reviewed working diff | Streamlined-sidebar handoff in the merged universal ledger | APPROVE. PRs #1112, #1116, and #1117 landed the universal-ledger baseline, two preserved UI tasks, and credential/hook hardening; this follow-up preserves that current-main schema and adds only the still-missing sidebar delivery as collision-free `#066`. The queue remains gap-free and every recommended ID has one open row. Sidebar implementation stays recoverable from remote branch `origin/codex/sidebar-test-fix-20260723` at full commit `cd54e68fbf7b07b5dffe3220e36af2caa528da54` until its local/browser/build/hosted merge proof is complete. | Focused sidebar/favourites tests previously passed 18/18 on the recorded implementation commit; this ledger follow-up passed Prettier, remote-ref recovery, 36-row contiguous-order/46-open-ID/next-ID invariants, and `git diff --check`. The broader reconciled precursor passed `verify:cheap` (365 files, 3,242 passed/1 skipped); fresh exact-head hosted CI is required on PR #1114. No OpenAI, Supabase, Railway, deployment, live-app, credential, or production-data action ran. |

Subject: [PATCH 05/16] fix: sync shared search shell mode on pathname
 navigation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Keep searchMode in sync when the shared (search-app) layout navigates
between mode homes with an unchanged empty query string (/services → /dsm).
Index the (search-app) route group for docs:check-index and merge latest main.

RAG impact: no retrieval behaviour change — shell URL sync and docs index only.

Subject: [PATCH 06/16] docs: sync PR #1134 policy body for CI gate

Provide PR_POLICY_BODY.md so Sync PR policy body can rewrite the
stale ledger-only description with RAG impact, verification,
risk, and clinical governance preflight. Update babysit ledger row.

+## Summary
+
+- Fix cross-mode search performance findings: prescribing catalogue debounce/abort/`fields=index`, differentials abort/debounce, universal documents typeahead soft-timeout (750ms), shared `(search-app)` shell to avoid composer remount, and Answer rate-limit in-memory fallback outside production.
+- Fix Bugbot regression: shared-shell pathname navigation (`/services` → `/dsm`) now syncs `searchMode` even when the query string is unchanged.
+
+RAG impact: no retrieval behaviour change — typeahead documents domain timeout and shell URL sync only; ranking formulas and full `/api/search` retrieval path unchanged.
+
+## Verification
+
+- [x] `npm run verify:pr-local` — focused Vitest on touched sources (362) plus api-rate-limit / search-shell / universal / route / site-map suites green; `docs:check-index` OK
+- [x] UI verification not run: full `verify:ui` not required for this pass; mode-home smoke via `npm run ensure` returned HTTP 200 for `/`, `/services`, `/dsm`, `/documents/search`, `/therapy-compass`, `/?mode=prescribing`, and `/api/answer/stream` returned 200 after the rate-limit fallback fix
+- Verification not run: `eval:retrieval:latency` / soak / live OpenAI canary — approval-gated provider work; not needed for timeout-only typeahead change
+
+## Risk and rollout
+
+- Risk: medium — shared layout remount change and rate-limit fallback behaviour in non-production; production Answer/upload still fail closed when the durable limiter is unavailable
+- Rollback: revert this PR; mode routes return to per-segment `GlobalSearchShell` layouts and prior timeout/fallback behaviour
+- Provider or production effects: None
+
+## Clinical Governance Preflight
+
+- [x] Source-backed claims still require linked source verification before clinical use
+- [x] No patient-identifiable document workflow was introduced or expanded without explicit governance approval
+- [x] Supabase target remains `[REDACTED]` (`[REDACTED]`)
+- [x] Service-role keys and private document access remain server-only
+- [x] Demo/synthetic content remains clearly separated from real clinical sources
+- [x] Source metadata, review status, and outdated/unknown-source behavior remain conservative
+- [x] Deployment classification/TGA SaMD impact was checked when clinical decision-support behavior changed
+
+## Notes
+
+- Prescribing list-row patient alerts that need full section rows remain on the medication detail page (`fields=index` strips sections by design).
+- Live hybrid RPC cold tails remain a separate approval-gated follow-up.

Subject: [PATCH 07/16] fix: sync searchMode during render; clear
 maintainability budget

Sync shared-shell URL mode during render so pathname-only navigations
do not paint a stale searchMode frame. Extract ClinicalDashboard lazy
imports and abort-controller helpers so the hotspot stays under budget.

+description: Get an open pull request merge-ready. Use proactively when the user asks to babysit a PR, fix CI, resolve review comments, or clear merge conflicts before merge.
+---
+
+You are a PR babysitter for this Database repository. Your job is to make the current PR merge-ready without merging it yourself.
+
+When invoked:
+
+1. Inspect branch, `git status`, PR mergeability, unresolved review threads, and required CI checks.
+2. Read `docs/codex-review-protocol.md` and `docs/branch-review-ledger.md` before reviewing.
+3. Fix merge conflicts by merging `origin/main` (never rebase/force-push).
+4. Fix valid review findings (including Bugbot) with the smallest scoped change; explain when you disagree.
+5. Fix CI failures caused by this PR's scope. Never weaken CI checks just to pass. If Static fails maintainability budgets, extract a cohesive module instead of raising the budget.
+6. Keep `PR_POLICY_BODY.md` current for clinical-risk / RAG-surface PRs so Sync PR policy body can rewrite the description (Summary, RAG impact, Verification, Risk, Clinical Governance Preflight).
+7. Push scoped fixes and re-watch required checks until mergeable + green + comments triaged.
+8. Record the babysit outcome in `docs/branch-review-ledger.md`.
+
+Hard stops:
+
+- Do not merge into `main` or enable auto-merge.
+- Do not run provider-backed gates without explicit approval.
+- Do not discard unrelated local work.
+- Prefer local/offline verification first (`verify:cheap` / focused Vitest / `docs:check-index`).

Subject: [PATCH 08/16] fix: keep full prescribing catalogue for safety filters

Drop fields=index from the prescribing workspace so Safety/Monitoring
chips and patient alerts still see section-derived signals. Debounce and
abort remain the keystroke-storm controls; identity-only consumers keep
fields=index.

-- Prescribing list-row patient alerts that need full section rows remain on the medication detail page (`fields=index` strips sections by design).
+- Prescribing list rows keep the full catalogue payload so Safety/Monitoring filters and patient alerts still see section-derived signals; keystroke storms are controlled by debounce + abort. `fields=index` remains for identity-only consumers (cross-mode links).

-You are a PR babysitter for this Database repository. Your job is to make the current PR merge-ready without merging it yourself.
-
-When invoked:
-
-1. Inspect branch, `git status`, PR mergeability, unresolved review threads, and required CI checks.
-2. Read `docs/codex-review-protocol.md` and `docs/branch-review-ledger.md` before reviewing.
-3. Fix merge conflicts by merging `origin/main` (never rebase/force-push).
-4. Fix valid review findings (including Bugbot) with the smallest scoped change; explain when you disagree.
-5. Fix CI failures caused by this PR's scope. Never weaken CI checks just to pass. If Static fails maintainability budgets, extract a cohesive module instead of raising the budget.
-6. Keep `PR_POLICY_BODY.md` current for clinical-risk / RAG-surface PRs so Sync PR policy body can rewrite the description (Summary, RAG impact, Verification, Risk, Clinical Governance Preflight).
-7. Push scoped fixes and re-watch required checks until mergeable + green + comments triaged.
-8. Record the babysit outcome in `docs/branch-review-ledger.md`.
-
-Hard stops:
-
-- Do not merge into `main` or enable auto-merge.
-- Do not run provider-backed gates without explicit approval.
-- Do not discard unrelated local work.
-- Prefer local/offline verification first (`verify:cheap` / focused Vitest / `docs:check-index`).

 - Scope: Targeted review of search bar/header/footer chrome behaviour after the edge-to-edge phone dock fix, plus durable repo rules for page-adaptive search chrome.
 - Outcome: No new P0/P1 search chrome defect found in the static review. Fixed one regression hazard: a stale ClinicalDashboard comment still instructed a 0.75rem hidden dock pad despite the implementation/tests requiring 0rem. Added durable search chrome behaviour rules in AGENTS.md and docs/search-chrome-behaviour.md, with a static guard tying the remembered rules to the hidden-reserve contract.
 - Checks: dependency shortcut section count; git diff --check; targeted rg for stale 0.75rem hidden-pad source wording (only negative test assertions remain); targeted Vitest command attempted but blocked by missing node_modules/vitest under Node 20.20.2 in this container.
