test(style-contract): deterministic Gate 2 tap-carrier enumeration (#293 finding 2) - #1962
Conversation
…-carrier enumeration Ledger #293 finding 2: the earlier rendered-interactive enumeration on the live-search route `/services?q=CMHT&run=1` was nondeterministic across repeated runs (6, 5, 4, 3, 3, 9 distinct sub-floor shapes) because it raced the async search render, and was reverted rather than landed. Finding 1 (the "min-height overridden to 0" claim) was separately refuted as an intentional `sm:min-h-0` desktop release and is untouched here. Adds a new Playwright test that closes finding 2 two ways at once, per #293's own revised "Next": runs on `/forms`'s no-query home (fixed-array content once its registry summary settles, never a live-search route) at a phone viewport (390x844, below the `sm:` breakpoint so the release does not apply), enumerates all `min-h-tap` carriers with an explicit `.sort()` so output never depends on DOM traversal or classList iteration order, and polls the enumeration itself until three consecutive reads agree rather than trusting `networkidle` (already known unusable on this app's routes per `ui-specifiers.spec.ts`). The test itself repeats three full navigate-and-enumerate cycles and asserts they agree exactly — the same shape of proof as the original six-run evidence — so a reintroduced race fails this test rather than surfacing as CI flake. Verified: narrow test passes in isolation and after a full spec-file run (10/10), full `verify:pr-local` passes (lint, typecheck, 606 test files / 6549 tests, RAG fixtures, medication-interaction index); the one red step, check:medication-lexicon-report, is a documented pre-existing flake on origin/main itself (ledger commit fd7429a: three unrelated PRs hit it with zero diff against main).

…merged #215, #210, and #293 were queued as `done` in this same PR, each citing a PR (#1949, #1953, #1962) that turned out still to be open, not merged — verified by checking whether each PR's actual file change is present on origin/main (none are). Reconciling the original `done` requests would have closed these rows while their fixes exist only on unmerged branches, one of which (#1949) currently has failing required CI. Converts all three to `update` requests documenting the correction and the real current state, so reconciling this PR now cannot close a row before its fix has actually landed. Leaves #98, #189, and #194 as `done` unchanged — those cite PR #1950 and PR #1947, both confirmed merged into main.

unparseable trailing heights are classified as violations rather than skipped:
treat non-finite parsed heights as matching the violation condition, while
preserving the existing threshold check for finite heights.
- Around line 265-273: Harden the tap-floor probe around tapFloor: make the
temporary element immune to document.body flex/grid sizing so its measured
height reflects the --spacing-tap value, then explicitly assert that tapFloor is
at least the documented 48px minimum before validating carriers. Preserve the
existing probe cleanup and carrier assertions.

Summary
#293finding 2 (DS V2 Gate 2's nondeterministic rendered-interactive enumeration). Finding 1 (the "min-h-tapoverridden to 0" claim) was already refuted in a prior session as an intentionalsm:min-h-0desktop release of the phone-only tap floor and is untouched by this PR.tests/ui-style-contract.spec.ts:min-h-tap carriers render at or above the tap floor at a phone viewport (Gate 2, #293 finding 2).What was nondeterministic (verified from the original finding text)
Per
docs/outstanding-issues.md#293anddocs/design-system/GATES.md§2 Gate 2, the original enumeration ran on the live-search route/services?q=CMHT&run=1. Six runs against one production build returned 6, 5, 4, 3, 3 and 9 distinct sub-floor control shapes, largely disjoint.waitForLoadState("networkidle")plus shape deduplication did not settle it — the audit was racing that route's async search+ranking render — and two consecutive agreeing runs turned out to be coincidence. The enumeration was written, shown to find a genuine defect class (elements carryingmin-h-tapwhose computedmin-heightreads 0), and then reverted rather than landed, because this spec matchesproductionSpecPattern(playwright.config.ts) and ships in the requiredProduction UIjob — an intermittent version would have blocked every merge in the repo.Fix, following #293's own revised "Next"
/forms's no-query home instead (FormsHomePage), which renders its task cards/pills from a fixed array once its registry summary fetch settles — not from ranked search results whose shape can legitimately vary run to run.#293's own "Next" calls a phone layout "the simpler, more deterministic surface":min-h-tap'ssm:release (finding 1) does not apply below that breakpoint, so a sub-floor carrier there is a genuine violation rather than the intentional desktop-width shape finding 1 already explained.networkidle—tests/ui-specifiers.spec.tsalready documentsnetworkidleas unusable on this app's routes (persistent background fetches keep it open past its timeout)..sort()on the shape list, independent of (3): the output must never depend onquerySelectorAlltraversal order orclassListiteration order, only on content.Playwright/Chromium environment note
Ran cleanly in this session's container: installed Chromium matched the pinned
playwright@1.62.1revision (chromium-1234/chromium_headless_shell-1234under/opt/pw-browsers), and both the isolated new test and the fullui-style-contract.spec.tsfile passed locally. This repo has documented Playwright/Chromium version drift in some other cloud/containerized environments (#312) — if a different environment reports a browser-revision mismatch, that's a known environment gap, not a regression in this change; do not force a mismatchedPLAYWRIGHT_CHROMIUM_EXECUTABLE_PATH, delegate to CI'sProduction UIjob instead.Verification
