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. Computed style showed `1px rgb(229,231,235)` where `2px rgb(11,111,134)` was intended. The same shape of gap let a rail-colour assertion compare a colour against a width and pass unconditionally. **Next:** for contracts where the visual IS the requirement (rails, forced-colors thickness, tap targets), assert `getComputedStyle` in a Playwright case rather than class names in a DOM test, and add the unlayered-component convention to the design-system contract check. **Stop:** do not convert existing passing DOM tests wholesale; add computed-style proof only where the effect carries the meaning. | PR #1316 Codex P2 finding; session 2026-07-28 | 2026-07-28 | -| #095 | P3 | issue | `PR required` reports failure for concurrency-cancelled jobs | **Outcome:** a red `PR required` means a real failure. **Detail:** the aggregate calls `require_success` on `coverage`/`production-ui`, so any push that supersedes an in-flight run reports `coverage result was cancelled` → exit 1, indistinguishable at a glance from a genuine failure.

Eleven such reds were produced on PR #1316 in one session, and `Production UI` never once ran to completion. **FIXED 2026-07-30:** the aggregate now distinguishes the two. `require_success` / `require_skipped_or_success` route a `cancelled` result through a shared `cancelled_error` helper instead of reporting it as a plain failure. **First attempt was invalid and hosted CI was the only thing that caught it:** it passed the workflow-level cancelled status function through an `env:` value, but GitHub allows those functions (success/failure/cancelled/always) ONLY in `if:` conditions, so `ci.yml` failed to parse — the run was named `.github/workflows/ci.yml` rather than `CI` and created **zero jobs**. Valid YAML and invalid Actions schema, so prettier, lint, typecheck, `check:github-actions` and the full unit suite all passed the broken file. Reading each job's own `cancelled` result needs no such expression and loses nothing, since a supersession cancels the upstream jobs anyway. A new guard now fails locally on any status-check function outside an `if:` across `.github/workflows/**` — and it immediately caught a second instance in the explanatory comment written to warn about the first, because expressions are interpolated inside `run:` blocks too. **Second review finding, also real:** the first working version exited on the first non-success, so a run that was cancelled AND broken — `safety` cancelled while `build` had already failed — announced "not a real failure" and hid the break entirely, which is worse than the ambiguity the change set out to remove. It also asserted supersession as fact, wrong for a hand-cancelled run. Now two-pass: every requirement is recorded before anything is reported, **genuine failures win and are all listed**, a concurrent cancellation is demoted to a `::warning::` context line, and the cancelled-only headline states both possible causes instead of asserting one. Mutation-proven: four cases fail against the first-exit version. The message is actionable rather than merely accurate: it names the supersession, points at the newest run for the current head, and tells a reader who finds NO newer run that the run was hand-cancelled, verified nothing, and must be re-run rather than merged past. Measured cost of the ambiguity before the fix: one 2026-07-30 session spent four separate investigations on `::error::changes result was cancelled` / `static-pr result was cancelled`, while PR #1401 merged straight through an unrelated red the repo had learned to ignore. **The tempting fix was rejected as unsafe.** Treating `cancelled` as neutral, or skipping the aggregate via `if: !cancelled()`, would make the red disappear — but GitHub counts a SKIPPED required check as PASSING, so a hand-cancelled run on the current head would become mergeable with nothing verified. The result therefore stays RED; only the diagnosis cost was removed. Guarded by seven cases in `tests/ci-cache-safety.test.ts` that EXECUTE the extracted aggregate script under synthetic job results rather than grepping the YAML (the defect was behavioural, and a structural assertion passed against it — see `#094`), including one that pins `if: always()` plus the wiring, and one that asserts no cancelled required job can ever exit 0. Mutation-proven: three of them fail against the pre-fix aggregate. **Stop:** do not relax `require_success` for genuine failures, and do not make this aggregate skippable — a skipped required check reads as green. | PR #1316 runs 30340972329 / 30341225585; session 2026-07-28 | 2026-07-28 | | #096 | P2 | task | PR #1316 review follow-ups — adoption-gate coverage closed | **Outcome:** the two remaining PR #1316 review findings are fixed on `main` with tests. **Do not chase the commits.** The seven Codex follow-up SHAs (`ff5b682`, `77cfe12`, `9840ed9`, `81ffb86`, `a5d6561`, `967e16c`, `e544d0d`) are **unreachable** — `git fetch origin ` fails for all seven, no open PR or branch carries them, and none was in the squash merge `4bcfeb90`. They were authored in a sandbox on a branch named `work` and never pushed, so the "follow-up PR metadata" each reported does not exist. **Durable source:** the [PR #1316 review threads](https://github.com/BigSimmo/Database/pull/1316/files) persist and describe every fix with file and line detail; re-derive from those, not from the hashes. **Was live on `main` through 2026-07-28:** the band adoption gate skipped query-backed root modes — `modeHrefToPagePath` returned null for `pathOnly === "/"`, so `/?mode=prescribing` and Documents never entered the route inventory and the root dashboard page was unchecked. Closed on PR #1394 (see Adoption-gate gap closed below). **Already fixed independently, no action:** favourites hub counts (`libraryCountsTrusted`), the document-search status derivation, the 401 session-expiry path, and the record-path duplicate notice. **Corrected 2026-07-28 — the Therapy Compass retry-waiter finding is NOT a live defect.** `use-therapy-data.ts:68` `retryWaitersRef` is genuinely unscoped, so a newer request can settle an older retry's promise, but no caller observes it: `useTherapyData` lives in the long-lived `TcProvider` (`bindings.tsx:206`) and `requestKey` derives only from `screen`, so it cannot change without the screen changing; the sole awaiting caller is the band's `AsyncButton` inside `search-screen.tsx:33`, which unmounts on that transition, and `workspace.tsx:36` uses `onClick={b.retryData}` which discards the promise. An earlier note here claimed a visible "Retry stops being busy" symptom — that was wrong and is retained only as the correction. It becomes real if a future caller ever awaits `retry()` from a control that survives a `requestKey` change. **Adoption-gate gap closed 2026-07-29.** Root-path and href-less modes now resolve to `src/app/(search-app)/page.tsx`. Closing it surfaced two further defects in the same gate that the original finding did not name: the hand-rolled walk was capped at two import hops while the root route's real chain is four (`layout -> shared-search-app-shell -> global-search-shell -> ClinicalDashboard -> document-search-results`), and it followed neither `layout.tsx` — which is where that route's band actually comes from, since the page renders only a pass-through — nor `dynamic(() => import(...))`, which is how the dashboard code-splits its mode workspaces. All three are fixed together with a bounded BFS; each was verified load-bearing by reverting it and watching the gate fail. **Stop:** not user-facing; do not let it block a release, and do not add waiter keying without a reproducer showing a still-mounted control whose busy state clears early. | PR #1316 review sweep; session 2026-07-28 | 2026-07-28 | | #097 | P3 | issue | Gitleaks reports a false red when the PR head moves mid-run | **Outcome:** a red `Gitleaks` means a secret was found, not that someone pushed. **Detail:** on 2026-07-28 the job triggered for head `9bace1d1` checked out that merge ref, then queried the API and built its range against head `40278453` — pushed seconds later and absent from the checkout. Git rejected the range (`fatal: Invalid revision range`), so it scanned `~0 bytes`, logged `no leaks found in partial scan`, and exited 1. The scan did not run at all, which is worse than a normal failure because the natural reading is "noise, ignore it". It cleared on its own once the head stopped moving (`23 commits scanned`, `~198 KB`, `no leaks found`). Both range endpoints resolve in any complete checkout — verified locally against the branch and the PR merge ref — so this is not a `fetch-depth` problem. **Next:** pin the scan to a range the job controls (`base.sha`..the checked-out head) instead of re-querying the API mid-run, so a concurrent push cannot invalidate it. **Related:** same push-churn family as #095. **Stop:** do not weaken the gate to a soft-pass; the fix is a stable range, not a tolerated failure. | PR #1316 runs 30344938800 / 30346797225; session 2026-07-28 | 2026-07-28 | | #098 | P2 | task | Offline round-trip budget harness for the hot routes | **Outcome:** per-scenario Supabase round-trip counts are pinned by a test, so an extra round trip on a hot path is a red gate rather than an inference. **Done 2026-07-29:** the measurement gap is closed — `Server-Timing` now covers `auth`/`ratelimit`/`scope` on `/api/answer`, `auth`/`ratelimit`/`search`/`total` on `/api/search`, and `auth`/`ratelimit` on `/api/answer/stream` (previously the route the UI actually calls emitted no header at all). Headers flush before the first SSE frame, so in-stream stages cannot reach a header and must NOT be routed through the governed `progress`/`final` contract. `tests/answer-route-preamble.test.ts` pins admission-before-scope (no scope call while the limiter is pending or after a deny) and the client-disconnect abort signal. **Next:** generalise it — wrap the Supabase client in a counting proxy and assert per-scenario query budgets over the existing offline suites — `scripts/eval-rag-offline.mjs`, `scripts/test-rag-offline.mjs`, `scripts/rag-offline-contract.mjs` and the contract fixture `scripts/fixtures/rag-offline-contract-tests.json`. **An earlier version of this row named `test-cache-path.mjs` and `check-rag-fixtures.mjs`** (corrected 2026-07-29, PR #1377 review, matching the audit's own retraction): neither exercises a RAG request — the first computes Vitest/TypeScript cache paths, the second only validates fixture manifests — so building the harness on them would have counted nothing.
