It does not reproduce in isolation, on a single spec, or locally. The documented workaround is to scope the locator to the visible root. **Reproduced locally 2026-07-28** (isolated _production_ build via `run-playwright.mjs`, full `verify:ui`): `ui-tools.spec.ts:563` duplicated `forms-home` and `ui-smoke.spec.ts:3001` duplicated `favourite-row-lithium-monitoring-guideline`; in both, copy 1 is nested under `mobile-composer-reserve-pad`. Both pass when run alone, so it is load/order-dependent, not build-mode dependent — this also corrects an earlier note that CI uses `next dev`; it does not. **Strongest evidence (CI run `30345484316`, 2026-07-28): `ui-overlap.spec.ts:199` on `/` asserted `toHaveCount(1)` successfully and then the same `header#search` locator resolved to 2 a statement later, one of them hidden.** A duplicate that appears _after_ a passing count assertion is a stream/hydration artifact by construction, not a static double mount and not something a CSS or component change can cause. That makes four distinct testids across four specs with the identical shape. **Mitigated, not fixed, on `main` (2026-07-28):** `3a8edb93` rewrapped `gotoHome` in `tests/ui-overlap.spec.ts` to retry count-and-visibility together via `toPass`, so a transient second header no longer trips strict mode there — its own note says "checking count then immediately calling waitFor races that flicker into a strict-mode violation". That hardens one helper; the duplicate root itself is unchanged and other specs remain exposed. **Confirmed pre-existing:** at `631d90d2`, the commit before PR #1316's first commit, that spec already documented "two `header#search` nodes" and "a second transient `header#search` can exist briefly" — so this predates that branch. **Next:** with a full-suite repro now available, bisect the preceding specs to find the state that triggers the second mount, then either scope the shared helpers to the visible root once or fix the mount. **Stop:** do not paper over new occurrences with `.first()` before the duplicate itself is explained. | PR #1316 CI runs; PR #1294 note on main; session 2026-07-28 | 2026-07-28 | | #094 | P2 | rec | Design-system gates assert structure, not rendered effect | **Outcome:** a style contract cannot pass while the style is inert. **Detail:** PR #1316's accent rail shipped inert because `.search-band` sat in `@layer components`, which loses to Tailwind's utilities layer regardless of specificity — and the test asserted `toHaveClass("search-band")`, i.e. class presence, not effect.

They do not. The route's auth, rate limiting, scope resolution, related-document enrichment and telemetry write are all invisible to this suite, so a round trip added to any of them leaves it green — and the refusal budget below is about *retrieval*, not about an adversarial HTTP request, which still pays the route preamble. **The measured shape is itself the finding:** one search costs **11 round trips** — `rag_aliases` 1, `match_document_chunks_text_v2` **3**, `match_document_table_facts_text_v2` **3**, `get_related_document_metadata_v2` 1, `document_index_quality` 1, `document_images` 2 — so the two text RPCs are each issued three times per search. Pinned by total *and* breakdown, because a refactor swapping one probe for an unrelated query would keep the total at 11 while changing the traffic. Deterministic across three consecutive runs. The refusal budget asserts **zero** Supabase traffic, matching `rag.ts`'s claim that prompt-injection intent is refused before any query issues, and was proven against the broken shape: with a non-refused query it fails on the round-trip assertion (`expected 11 to be +0`), which is why that assertion is ordered ahead of the results assertion. **Next:** (a) add the route-level budget this suite does not provide — drive `POST` from `src/app/api/search/route.ts` with counted clients, following the `tests/answer-route-preamble.test.ts` pattern, so a round trip added to the route preamble or post-processing is a red gate; (b) decide whether `match_document_chunks_text_v2` ×3 and `match_document_table_facts_text_v2` ×3 per search are intended or a probe that should be collapsed — a latency question this budget surfaced but does not answer, and one that touches retrieval, so any change needs the usual RAG gate. (c) `scripts/eval-rag-offline.mjs` and `scripts/test-rag-offline.mjs` remain unwired; the offline contract runner is now the de-facto single home for budgets, so either adopt that explicitly here or wire them. | `docs/audit/latency-audit-2026-07-28.md` measurement plan; `src/lib/server-timing.ts`; `src/lib/answer-stream-contract.ts:18-21` | 2026-07-29 | | #099 | P2 | task | Remove the remaining fixed per-request round trips | **Outcome:** the answer path stops paying avoidable per-request Supabase round trips. **Done 2026-07-29:** shared-cache-hit promotion deferred off the response path with its mid-request staleness guard intact and documented (`rag.ts:3234`, `rag-cache.ts`); scope resolution overlapped with the rate-limit RPC, signal threaded so a client disconnect finally cancels its paginated queries (`answer/route.ts`). **REFUTED on PR #1377 review — do not retry:** the same pass also overlapped scope with the rate-limit RPC and aborted it on deny, claiming the limiter could "deny for free". It cannot. With caller-supplied `filters` or explicit ids, scope passes its zero-query early returns (`search-scope.ts:242,253`) into the paginated `documents` loop at `:269`, and an `AbortSignal` cancels the client request without un-executing a statement Postgres already began — so throttled traffic kept burning database capacity while collecting 429s, against `capacity-review.md:106-113`'s first-soft-failure warning. Scope is behind admission again, pinned by `tests/answer-route-preamble.test.ts`. Re-attempting the overlap requires a non-database admission gate ahead of the durable limiter first. **Remaining:** (a) the 8 `setCachedSearch` awaits — deferring changes `throwIfAborted` semantics and widens a real mutation window because the clone happens after an `await`, so each branch needs discharging individually; (b) batch the anonymous subject+global rate-limit pair, which needs a NEW atomic RPC modelled on `consume_summary_rate_limits_atomic` and cannot be called until the operator applies it — `Promise.all` is the WRONG fix because it consumes the global bucket even when the subject bucket already denied; (c) stop the proxy and route handler resolving identity twice per authenticated request — no in-process memo can do this (different `Request` objects), so the proxy must forward unspoofable verified claims via a header it controls.

Only the documents-list use stays ordering-safe; `(status,id)` is canary-gated too — see runbook, and making that `.limit(12)` deterministic first does **not** lift the gate — an unordered `LIMIT` has no stable selection to preserve, so imposing an order can pick a different twelve and is itself an ordering behaviour change on a retrieval surface, which AGENTS.md requires a canary pair for. Sequencing the ordering fix first is worthwhile (unordered `LIMIT` on a retrieval input is latent nondeterminism regardless) but yields two canary-gated changes, not one (PR #1377 review). **Deliberately NO migration file:** an additive-index migration without a synchronized `schema.sql` mirror and regenerated drift manifest is exactly what closed PR #1312, and the mirror cannot come first because `required_indexes` in `search_schema_health()` (`schema.sql:3178`) runs against live. **Next (operator):** **author the migration first** — `supabase/migrations/` is the source of truth and `schema.sql` only a mirror, so hand-run operator SQL never reaches staging, disaster-recovery replay, or a local `supabase db reset`, and a `required_indexes` registration would fail there (PR #1377 review); follow the `20260717170000_registry_projection_cleanup.sql` idempotent pattern. **That migration must also carry the health-function change** — `required_indexes` lives inside `search_schema_health()`, which is redefined by `create or replace function` in eleven migrations (copy `20260705180000_reconcile_search_health_indexes.sql:62`); editing `schema.sql:3177` alone moves only the mirror and leaves the indexes unmonitored on hosted (PR #1377 review). Then apply concurrently, confirm `indisvalid`, mirror both the index statements and the identical function body into `schema.sql`, run `npm run drift:manifest` (Docker), and deploy the migration LAST — in that order, in one change. Expect `check:drift` to report them as unexpected between steps 1 and 2. **Rollback is three deployed phases, not the reverse of one:** retract `required_indexes` via its own `create or replace function` migration and deploy → drop concurrently live → only then deploy the `schema.sql` removal plus an idempotent forward `drop index if exists` migration, because Supabase wraps migrations in a transaction and a plain `DROP INDEX` there takes the lock the concurrent procedure exists to avoid (PR #1377 review). | `docs/audit/latency-audit-2026-07-28.md` L2-3/L2-5; `docs/operator-apply-performance-latency-remediation.md` | 2026-07-29 | | #103 | P2 | issue | Wide table-facts trigram index missing from `schema.sql` | **Outcome:** the migration chain and `schema.sql` agree on `document_table_facts` trigram indexes. `supabase/migrations/20260714190000_document_table_facts_trgm_idx.sql` creates a wide 5-column trigram index that is **absent from `supabase/schema.sql`**, so local replay and the live database can diverge. Distinct from #102: different owner and verification path. **Next:** confirm whether the wide index exists live, then take one of exactly two routes — **retained:** mirror `document_table_facts_text_trgm_idx` into `supabase/schema.sql` beside the narrow one and regenerate `drift-manifest.json`; **redundant:** drop it through a new forward migration, never by deleting `20260714190000`. **`drift-allowlist.json` is NOT a third option** (PR #1377 review): its own header scopes it to _"Known live-vs-`schema.sql` divergence"_, so it can silence a live drift finding but cannot reconcile the migration chain with the mirror — a fresh `supabase db reset` still runs `20260714190000` and creates the index while `schema.sql` still omits it, leaving this row's stated outcome unmet. **No offline gate catches this today:** the migration↔`schema.sql` parity test (`tests/drift-detection.test.ts:59-68`) only asserts one migration's `schema_drift_snapshot` function definition, not an index inventory — which is why this sits open rather than red in CI, and why a replay-to-schema inventory comparison is the check that would have caught it. Note the narrow `document_table_facts_title_row_param_trgm_idx` (`schema.sql:6425`) is the one the effective RPC expression (`:6726`) actually matches, so the wide index may be genuinely redundant — do not drop it without live scan evidence, per the monitored-not-auto-fixed index policy. | `docs/audit/latency-audit-2026-07-28.md` limitations; `npm run check:drift` | 2026-07-29 | | #110 | P3 | task | Design-system project token manifest lags its stylesheet | **Outcome:** the claude.ai/design token panel matches the shipped stylesheet. **Detail:** PR #1375 pushed a recompiled `_ds_bundle.css` (Clinical Sky, `--e0`–`--e4`, 4px radius grid, `--tracking-eyebrow`/`--leading-display`/`--leading-prose`) plus the four changed guideline docs to project `08d6f126`, but `_ds_manifest.json` is converter-generated and still advertises `--text-4xs: 0.5rem`, the old `--radius-lg/xl/2xl` values, and `--tw-leading`/`--tw-tracking` entries scoped to the retired `.leading-[…]` / `.tracking-[0.08em]` utilities.

So a sandboxed session has no way to bridge the builds, and the honest options reduce to two: request the write permission explicitly, or state that no browser evidence is available and leave the browser claim unmade. **Retracted the same day, by me:** the sentence above claiming the options "reduce to two" was wrong, and it is left standing rather than deleted because the retraction is the useful part. There is a third route that needs no filesystem write at all: **`PLAYWRIGHT_CHROMIUM_EXECUTABLE_PATH`**, read by `playwright.config.ts:11` and honoured by the preflight (`scripts/playwright-browser-preflight.mjs:101`), pointed at the container's existing `1194` binary. Verified by launching it, not by reading the flag: `chromium.launch({ executablePath: "/opt/pw-browsers/chromium_headless_shell-1194/chrome-linux/headless_shell" })` under the repo's Playwright 1.62 client reported `version 141.0.7390.37`, rendered a page and measured a `boundingBox` of the expected height. So a sandboxed remote session **can** produce browser evidence, and the earlier claim that it cannot was an over-generalisation from one blocked `mkdir`.

Both guards therefore protect exactly the environment least likely to break the rule, which is why the AGENTS.md format-before-push instruction is still load-bearing even though the tooling now exists. Observed directly on PR #1400: a push landed while auto-merge was armed with nothing to stop it. **Next:** provide `gh` (or a token-based equivalent) in agent environments so the sentinel can evaluate. **Do not move the format check into `pull_request_target`** — that context carries secrets and a write token, and a format check must execute PR-head code including this repo's now-loadable dynamic `prettier.config.*`, which is the classic privileged-context vector; `.github/workflows/pr-policy.yml` deliberately checks out only `github.workflow_sha` for exactly this reason. Formatting is already enforced server-side by `Static PR checks` running `format:check` on ordinary `pull_request` CI, so the guard's only unique value is failing fast before the push — nothing to duplicate.

Stripping the padding and running `prettier --write` restored the file byte-for-byte identical to the original, so un-padding requires prettier-ignoring the file — which PR #1479 does, following the precedent already set for `docs/branch-review-ledger.md`. Nothing structural is lost: `check:outstanding-issues` gates row shape, ids, the marker and the merge attribute far more strictly than column alignment ever did. **The mechanism is narrower than this row claimed.** "A single row's edit re-pads all 59 open rows" holds only when the edit raises a column's **maximum** width; an edit inside the existing maxima is 2 changed lines either way. Measured on the real file: lengthening a Detail cell = 2 lines padded and 2 un-padded; widening a Summary past the column max = **144 lines padded vs 2 un-padded**. Appending a new row is precisely the max-raising operation, and appending is what agents do to this file constantly, so the worst case was also the common case. **Stop:** do not re-enable Prettier on this file to "tidy" the table; the alignment is the defect. | `.prettierignore`; `.gitattributes`; `scripts/check-outstanding-issues.mjs`; PR #1444; PR #1479 | 2026-07-30 | | #142 | P3 | task | Four loose dated docs need source and migration edits before they can be filed | **Outcome:** every dated point-in-time doc lives in `docs/audit/` or `docs/archive/` as `docs/README.md` requires, not loose at the `docs/` top level. **Detail:** PR #1436 filed the five that were docs-only moves. These four are referenced from outside `docs/`, so relocating them means editing source, tests and migration SQL comments — a different risk class than a docs tidy, and not worth bundling into one: `capacity-review.md` (`scripts/soak-test.ts`), `tenancy-defense-in-depth-review.md` (`src/lib/owner-scope.ts`, `tests/owner-scope-guard.test.ts`, two migrations, `SECURITY.md`, `.claude/agents/clinical-governance-reviewer.md`), `operator-apply-july8-batch.md` (three migrations plus `supabase/schema.sql`), `scale-readiness-review.md` (one migration). Also note `forward-codify-retrieval-rpcs-workorder.md` is indexed as a completed workorder but live is still ahead of the repo on those RPCs, so archiving it would misrepresent open operator work. **Next:** treat as low priority — the docs are correctly indexed and reachable where they are; only file them if a pass is already editing those migrations.
