This row's fixed member left a standing worry in its own text: that the Next 16 prefetch-header trap is generic to any Playwright assertion trying to tell a prefetch from a navigation, and was worth grepping for. GREPPED, on origin/main 0177bed: grep -rn 'next-router-prefetch' over tests/, src/ and scripts/ returns two hits, both inside the already-fixed tests/ui-smoke.spec.ts:1354 block (its explanatory comment and the corrected guard). There is no second occurrence anywhere in the repository, so that specific trap is not lurking elsewhere and no further code fix follows from it. WHAT REMAINS UNEXPLAINED: the other three single-spec Production UI failures of 2026-09-02. This row never named them, and the only pointers are CI runs 33610490607 and 33613433031, which are past the useful retention window for reading logs. With no spec identities and no reproduction, any fix would be a guess, and guessing at flakiness is how a real failure gets quarantined by accident. RECOMMENDATION: leave open at P3 as a watch item, not a work item. If a fourth single-spec Production UI failure appears, capture the spec identity and the run URL AT THAT MOMENT - that is the missing input - then reproduce with --repeat-each on the same SHA before touching anything. Do not quarantine; tests/flake-ledger.json still holds one entry and it is not one of these.",

FIRST HALF IS FIXED, NOT BY THIS ROW: npm run test:e2e:ward-journeys now reports 71 passed, 3 skipped, 0 failed. The eight failures this row recorded are gone. Two of the three skips are the ui-ward-morning pair, and their skip is a documented owner-approved decision rather than a silencing: MERGE 02 (2026-09-05) folded the morning board into CapacityScreen, /mockups/ward-flow/morning is now a redirect stub, MorningPage is unmounted, and morning-page.tsx's own doc comment forbids retargeting the spec at CapacityScreen or re-mounting the component pending the owner's ruling on spec D9. Component-level coverage continues in tests/ward-morning-page.dom.test.tsx (20 cases) and tests/ward-morning-print.test.ts. SECOND HALF WAS 'BUILT BUT INERT' UNDER vars.WARD_JOURNEYS_BLOCKING; THAT GATE IS GONE IN CODE. The blocking lane ui-ward-journeys in .github/workflows/ci.yml no longer scopes on ward paths \u2014 it gates on needs.changes.outputs.ui_changed \u2014 so the path-scoped blind spot this row named is designed out. Concurrent #2710 (ci(ward-flow): require journey coverage) enables that lane in ci.yml and drops the vars.WARD_JOURNEYS_BLOCKING term from both the job if: and the matching pr-required require_success condition; the lane runs on pull_request|merge_group when ui_changed and not draft. No repository variable flip is required or useful after #2710. Do not set WARD_JOURNEYS_BLOCKING \u2014 the variable is obsolete once #2710 lands. NEXT ACTION: once #2710 is on main, confirm one non-draft UI PR shows ui-ward-journeys / ward-flow-journeys reporting (not skipped-and-fine solely because of a missing repo var), then close this row.
