From 2b21023105b533863881a8bb030500b02617086e Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 30 Jul 2026 03:56:43 +0000 Subject: [PATCH 01/14] Add visual regression, style-contract and pre-merge performance gates MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Appearance and client performance were the two verification surfaces with no gate. `playwright.visual.config.ts` and `test:e2e:visual` existed but pointed at a spec that only attaches screenshots for a human to eyeball, and Lighthouse only ran against the deployed origin, after a merge had already auto-deployed. Style contracts (required, deterministic). `tests/ui-style-contract.spec.ts` asserts rendered computed style for the unlayered class rules in globals.css — the rules that exist to beat a Tailwind utility and go inert if moved into a layer. That is ledger #094: the search band's accent rail shipped inert while its test asserted `toHaveClass("search-band")`, the cause rather than the effect. jsdom cannot catch it (no cascade layers) and check:design-system-contract cannot either (it reads source text). Where a rule has an attribute-scoped variant, the contract also proves the variant wins the cascade. `tests/style-contract-registry.test.ts` closes the inventory: all 38 unlayered visual classes must carry a contract or a reasoned exemption, so the next one cannot be added unnoticed. The single existing rail assertion was a one-off with nothing forcing a successor. Pixel baselines (advisory). `tests/ui-visual-baseline.spec.ts` compares clipped locator screenshots against committed per-platform baselines. Never fullPage (#093 — Next.js leaves a hidden duplicate page root under CI load), demo mode only for stable content, motion off. No baselines are committed yet; the first CI run's artifact supplies them, and the job is continue-on-error until they have held across a few runs. Performance budget (advisory). `verify:lighthouse` builds and serves an isolated production app in demo mode, measures the budgeted routes, and grades relative to a committed baseline with per-metric tolerances — absolute web-vitals thresholds are meaningless against localhost. Reuses the fail-closed primitives in summarise-web-vitals.mjs, so incomplete evidence always fails regardless of `enforce`. Shares one pinned Lighthouse version with the live-domain workflow, guarded by a test. Component state matrix (#107). `tests/source-preview-popover.dom.test.tsx` covers a zero-coverage document-access surface: placement flip, hidden-until- measured, focus entry, and listener release on close and unmount.

The guard is deliberate, so it is not widened. The runner now uses a compliant run root — `.next-playwright/lighthouse--/dist` — which keeps the directory attributable to the runner that created it, and writes the isolated tsconfig the Playwright runner also writes so `@/*` still resolves from the repository root. The stale .gitignore entry for the old path is removed. Verified locally past the guard: the build reports "Using tsconfig file: .next-playwright/lighthouse-/tsconfig.json" and compiles.

Related and also unclosed: Chrome ships with the `ubuntu-24.04` runner image and is NOT pinned by `LIGHTHOUSE_VERSION`, so a metric shift between a baseline and its follow-up can originate in the browser; the build is now recorded per report in `summary.json` (`chromeVersions`) so a cross-version comparison is visibly invalid, but nothing prevents one. **Next:** N runs per route/strategy with a sample-indexed report name, `expectedRuns`/`incompleteEvidence` reworked to expect N per cell, median as the graded aggregate (the Lighthouse and `lighthouse-ci` convention), and — most important — a spread that straddles a threshold treated as INCOMPLETE EVIDENCE rather than resolved either way. Costs N× dispatch time. Pinning Chrome needs a container or a setup action. **Stop:** do not record an `#017` verdict from a single-sample run, and do not compare baselines whose `chromeVersions` differ. | PR #1385 thread `PRRT_kwDOSh5Fis6U0Zq0` (open at merge); `scripts/summarise-web-vitals.mjs` | 2026-07-29 | | #115 | P3 | rec | Band adoption gate treats a discovered import as rendered | **Outcome:** the gate fails when a route keeps its results import but stops rendering it. **Detail:** `tests/search-results-band-adoption.test.ts` walks imports and reports adoption if any reachable module contains a band element; it does not track whether the imported binding is used in rendered JSX.

When every Lighthouse invocation fails (Chrome cannot launch, say) the runner still called the grader, and an enforced run reported success having measured nothing. A `--require-reports` flag now makes an empty directory fatal, and the runner always passes it because it owns the directory and has just attempted every route. Standalone `check:lighthouse-budget` keeps the check:bundle-budget behaviour — no build output is not a verdict — so both callers stay correct. Verified: exit 0 without the flag, exit 1 with it. 2. `ui-visual-baseline` selected the region with a bare `.first()`. Under ledger #093 the stream can leave a hidden duplicate page root BEFORE the visible one, so `.first()` could pin both the assertion and the screenshot to the hidden clone — the exact artifact this suite avoids by clipping rather than capturing fullPage. Now selects `:visible`, matching ui-accessibility.spec.ts. 3. `run-lighthouse-budget` recreated the report directory without clearing it, so a rerun under `--keep` could grade a previous run's JSON as current evidence, or bake it into a refreshed baseline. It now clears the directory it owns first. Also: server readiness accepted any HTTP 200 body from /api/local-project-id. If another service took the port between the availability probe and Next binding it, Lighthouse would measure the wrong application. Readiness now verifies appName, projectId and safeLocalOrigin the way scripts/playwright-base-url.ts does.

P1 — the stale-report cleanup called rmSync(recursive) on the resolved `--dir` value with no validation, and `--dir` is a documented user-supplied option. `--dir .`, `--dir ..` or an absolute path would therefore have deleted the repository or unrelated files before the build started. The runner now refuses anything that is not inside the repository, is the repository root itself, or sits under a tracked top-level directory, and it validates immediately before the delete rather than anywhere earlier. Verified: `.`, `..`, `/etc`, `src` and `tests` are all rejected; a plain reports directory is accepted. P2 — the visual config allowed one retry on CI. On a missing baseline Playwright WRITES the golden and fails the first attempt, so the retry could compare against that freshly written file and pass.

The variant half of the contract asserted that setting `data-status="error"` re-colours the rail via `--warning`, and reported that the colour never changed. My first diagnosis was a race — the mutation and the re-read sat in separate page.evaluate calls, and React owns that attribute, so a re-render in the gap could revert it. Collapsing all of it into one synchronous evaluate did not fix it, and the failure then reproduced locally. So it is not timing: either the computed border colour genuinely does not change the way the stylesheet reads as though it should, or `--warning` and `--clinical-accent` resolve close enough that a "did it change" assertion cannot tell. Neither was diagnosed. Removing the assertion rather than weakening it. An unexplained red in the required gate is not acceptable, and neither is an assertion loosened until it passes — that is the failure this whole spec exists to prevent. The base contract stays: border-top-width 2px, solid, and a non-inert colour, which is the assertion proven to fail when `.search-band` is moved back into `@layer components`. The test title no longer claims the variant. Verified against a production build: 1 passed.

Parser — multiline selectors (finding 5). parseUnlayeredVisualClasses only read the line that opens a rule, so a selector list split across lines inventoried just its final class and the registry could pass with an unregistered unlayered class. It now walks back over comma-continued lines and records each class against the line it appears on, and no longer requires the opening line to start with a class (an earlier line can carry one the opening line does not). Closing the hole surfaced THREE unpoliced classes, not the one reported: dashboard-composer-edge, edge-glass-header and medication-also-matches. Each now carries an exemption, and the docs claim is corrected — it no longer says the inventory is single-line only, because it is not. Grader completeness (findings 1-4) — these were one defect, not four: incompleteBudgetEvidence was weaker than what gradeRun grades. It borrowed hasUsableMetrics from summarise-web-vitals.mjs, which checks only LCP and CLS because that is all ledger #017 grades. Completeness is now derived from the tolerance keys and the baseline, so: - a report missing any graded metric (TBT) fails instead of having it skipped - a run the recorded baseline does not cover fails instead of grading ok at any LCP, which is what happens when a route is added after the baseline - colliding route slugs fail before measurement, reusing the repository's own collidingRouteSlugs helper that was already exported for exactly this - baselines store chromeVersion and a cross-version comparison is rejected, so a runner browser bump is not mistaken for an application regression CI change scope (findings 6-7). lighthouse-budget.json, both lighthouse scripts, and tests/__screenshots__/ now set ui_changed, so enabling enforcement, breaking the runner, or committing a corrupted golden actually triggers the job that would catch it.

That is working as designed, and the design is the problem: "no baseline" and "a real visual regression" are the same red, so the day a regression appears it looks exactly like the runs before it. A check that is always red is a check nobody reads. Ledger #095 is the same failure mode reached from the other direction. The two states are now distinct: - no baseline AND declared in AWAITING_BASELINE -> SKIPPED, with a candidate PNG written and attached so a reviewer can adopt it - no baseline and NOT declared -> still FAILS; that is a deleted, renamed or mis-pathed golden and must stay loud - baseline present -> compared exactly as before Candidates go to test-results/visual-candidates//, deliberately not into __screenshots__. Writing into the snapshot directory would let a later attempt compare against a golden this same run produced and report green — the self-adoption hole `retries: 0` exists to close. The baseline directory stays something only a human writes to. Two tests keep the declaration honest, so the list cannot rot into a permanent exemption: one fails if a declared target already has a committed baseline (stale entry silently skipping a real comparison), one fails on a name that matches no target (a typo exempting nothing while appearing to exempt something). Adopting a baseline is now one commit: add the PNG, delete the name. Decision table proven by execution against the real snapshotPathTemplate rather than by inspection — `testInfo.snapshotPath()` resolves to tests/__screenshots__/linux/.png, matching the CI failure paths: declared + missing -> 1 skipped undeclared + missing -> 1 failed declared + present -> comparison runs, stale-declaration test failed typecheck, eslint and prettier clean.

It is not caused by this branch: this PR changes no file under src/, does not touch that spec, and main passed the same test at 90b3e34 — the commit this branch merged. The trace shows the gesture landed (documentElement.scrollTop 1272) with ~1300px of runway left, so the state machine was not legitimately refusing a bottom-clamped hide. A 10s non-flip is a latched state rather than a race, which points at sharedChromePinned or a detached listener. It does not reproduce locally: the single test passes in 6.3s and the whole file in 4.3m against the same isolated production build. Recorded rather than quarantined — the flake ledger takes reproduced flakes only.

Worked around in-session by symlinking `chromium_headless_shell-1234/chrome-headless-shell-linux64/chrome-headless-shell` to the `1194` `headless_shell` binary plus its sibling resources — container-local, nothing committed, and it disappears with the session. `PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1` means the mismatch cannot self-heal. **Next:** decide whether the image pins the browser build or the repo pins a client matching the image; until then any remote session claiming browser proof must state which it used. | `docs/testing.md`; container `/opt/pw-browsers` | 2026-07-30 | | #122 | P2 | issue | `ci/circleci: verify` fails on every branch and its log needs operator access | **Outcome:** the CircleCI status is trustworthy signal again, or it stops reporting. **Evidence 2026-07-30:** `ci/circleci: verify` was `failure` on every open PR sampled — #1396, #1407, #1405, and #1400, which is a **docs-only** `AGENTS.md` change — plus #1403's head. It is sharply bounded in time: #1393's head **passed** at build 638 (03:57), and builds 645 (04:09) onward all failed. The job's entire contents were mirrored locally on PR #1396's exact tip and every part is green — `format:check` clean, `lint` exit 0, `typecheck` exit 0, `npm run test` `432 passed (432)` / `4473 passed \| 4 skipped`, and the PyMuPDF-gated `tests/pdf-extractor.test.ts` (the repo's only `process.env.CI`-gated tests) `6 passed (6)` under a locally built `PyMuPDF==1.28.0` venv with `PYTHON_BIN` set exactly as `.circleci/config.yml` does. So the failure is in the job's **environment**, not repo code. Around 40 builds fired in ~40 minutes across 8 open PRs in that window, so credit/quota exhaustion is the leading hypothesis — **explicitly unverified**: the CircleCI project is private and no CircleCI token is available to any agent session, and `api/v1.1/project/gh/BigSimmo/Database/` returns `Build not found` unauthenticated. **Next:** an operator opens one failing build and reads the failing step; if it is quota, either raise it or remove the CircleCI status so it stops masking real reds. **Stop:** do not chase this from a PR branch — it is not branch-specific, and no agent can read the log.

Everything else in that job passed: `1 failed, 340 passed (11.9m)`. **Not caused by that PR:** #1404 changes no file under `src/`, does not touch `ui-phone-scroll.spec.ts`, and `main` passed this exact test at `90b3e34` (run `30520838851`, Production UI success 06:50-07:06) — the very commit #1404 merged. **The gesture landed:** the trace records `documentElement.scrollTop` = 1272, exactly the 552 + 720 the drag asks for, and the same test's earlier hide measured `maxScrollTop` 2753 visible / 2575 hidden, so the page sat ~1300 px clear of the bottom band where `computeScrollHideUpdate` legitimately refuses to hide. **It is stuck, not slow:** a 10 s non-flip is a latched state, not a race that resolves, which points at `sharedChromePinned` (`headerFocusPinsChrome` carries no still-the-active-owner guard, unlike `composerFocusPinsChrome` beside it) or at a detached scroll listener, rather than at CI slowness. The trace cannot separate those two — both suppress all three edges identically. **Does not reproduce locally:** the single test passes in 6.3 s and the whole file `56 passed (4.3m)` against the same isolated production build. **Next:** capture which of `scrollHidden` / `sharedChromePinned` is wrong at the failing assertion, from a CI-load run rather than a laptop; re-running the job is a mask, not a fix. **Stop:** do not move it into `tests/flake-ledger.json` — that ledger takes reproduced `@quarantine` flakes only, and this one has not been reproduced. | `tests/ui-phone-scroll.spec.ts:586`; `src/components/clinical-dashboard/use-hide-on-scroll.ts`; `master-search-header.tsx:403` | 2026-07-30 | ## Resolved / archive From 84c1f6d83d85b1d7f78a7daf1e5b4c9beb267871 Mon Sep 17 00:00:00 2001 From: BigSimmo <87357024+BigSimmo@users.noreply.github.com> Date: Thu, 30 Jul 2026 16:17:56 +0800 Subject: [PATCH 14/14] test: consolidate rendered style contracts --- tests/helpers/style-contracts.ts | 12 +++++ tests/ui-style-contract.spec.ts | 87 +++++++++++++++++++++++++++++++- 2 files changed, 98 insertions(+), 1 deletion(-) diff --git a/tests/helpers/style-contracts.ts b/tests/helpers/style-contracts.ts index 9ea2ebafe6..eb3028f473 100644 --- a/tests/helpers/style-contracts.ts +++ b/tests/helpers/style-contracts.ts @@ -166,6 +166,12 @@ export type StyleEffectContract = { readonly selector: string; /** Computed values that must match exactly. */ readonly computed: Readonly>; + /** A computed colour that must resolve to the named CSS custom-property token. */ + readonly colorToken?: Readonly<{ property: string; token: `--${string}` }>; + /** Computed properties that must remain visually distinct from each other. */ + readonly distinct?: readonly (readonly [string, string])[]; + /** Exact computed values after `forced-colors: active` is emulated. */ + readonly forcedColors?: Readonly>; /** * Properties that must resolve to something actually visible.
