Fix is client-only."

# Phase 12 Plan 07: UAT Gap-Closure (gaps 5 & 6) Summary

**The /setup wizard no longer re-mounts after completion (shows Surface 8 'Setup already complete'), and the '/calendar' setup banner no longer nags the operator after they finish the wizard — fixed by reverse-gating the route and making the ['me'] query fresh on shell entry.**

## Performance

- **Duration:** ~11 min
- **Started:** 2026-06-16T21:19Z
- **Completed:** 2026-06-16T21:24Z
- **Tasks:** 2
- **Files modified:** 4 (3 modified, 1 created)

## Accomplishments

- **Gap 5 closed:** `/setup` is now reverse-gated on `setupComplete`. After completion, manually visiting `/setup` renders `SetupPage alreadyLocked` → Surface 8 "Setup already complete" (the backend already 423s setup mutations; this is the matching frontend gate). Loading state renders a no-flash placeholder; `setupComplete===false` still mounts the active wizard.
- **Gap 6 closed:** the "Set up your calendar" banner no longer persists after the operator completes the wizard. Root cause confirmed as a `['me']` cache-staleness gap (mechanism ii), NOT a backend linking gap. Set `['me']` `staleTime` to 0 in both `App.tsx` (boot) and `SetupBanner.tsx` so a pre-claim stale entry is refetched on entry to the authenticated shell — `needsProviderSetup` then reflects the just-claimed credential and the banner hides.
- **Regression coverage added:** new `SetupBanner.test.tsx` (3 tests) + 2 new App reverse-gate tests. Full PWA suite green at 258 tests; typecheck clean.

## Gap 6 — Root Cause Investigation (Task 2 Step A)

The UAT `root_cause` was flagged PRELIMINARY. Reading `apps/api/src/auth/user.ts` `upsertUser` confirmed the first-login claim branch (lines ~118-130) updates the unclaimed row via `where(eq(users.id, unclaimed.id))` — it **preserves the same `users.id`**. Because `member_credentials` is keyed on `userId`, the wizard-stored CalDAV credential stays linked to the claimed operator row, so the DB correctly returns `needsProviderSetup=false` after first OIDC login.

**Conclusion: mechanism (i) (a backend claiming/linking gap) is NOT the cause** — consistent with the 12-03 summary and threat-register disposition `T-12-10 = accept`. The cause is **mechanism (ii)**: `['me']` had `staleTime: 5 * 60 * 1000`, so a cache entry populated before the claim (e.g. a pre-auth visit) served `needsProviderSetup=true` for up to 5 minutes after the operator authenticated post-wizard. No backend change was made; the fix is purely client-side cache freshness.

## Task Commits

1. **Task 1: Gate the /setup route on setupComplete (gap 5)** — `fdcb4dc` (feat)
   - (also carried the App.tsx `['me']` staleTime → 0 edit, staged together; the SetupBanner-side change + its test landed in Task 2)
2. **Task 2: Diagnose + fix the persistent calendar banner (gap 6)** — `2b3569f` (fix)

## Files Created/Modified

- `apps/pwa/src/App.tsx` — reverse-gated `/setup` route element (loading placeholder / `alreadyLocked` Surface 8 / active wizard); boot `['me']` `staleTime` → 0 with mechanism note.
- `apps/pwa/src/components/SetupBanner.tsx` — `['me']` `staleTime` 5min → 0 (gap-6 freshness); no dismiss button added; success-only dismissal contract restated in comments.
- `apps/pwa/src/App.test.tsx` — SetupPage mock now respects `alreadyLocked`; 2 new reverse-gate tests (already-complete surface + active wizard on `/setup`).
- `apps/pwa/src/components/SetupBanner.test.tsx` — NEW: banner absent when `needsProviderSetup=false`, present (no dismiss button) when true, and stale-cache refetch hides the banner on mount (staleTime 0).

## Decisions Made

- **D-12-07-GAP6-MECH** — gap 6 is mechanism (ii) `['me']` staleness, not a linking gap (evidence: id-preserving claim in `upsertUser`).
- **D-12-07-STALE0** — `['me']` `staleTime` set to 0 in App.tsx + SetupBanner.tsx; success-only dismissal contract preserved.
- **D-12-07-LOCKED-PROP** — `/setup` reverse-gate uses the `alreadyLocked` prop (Surface 8), not `Navigate`, per the UAT expectation that manual `/setup` navigation shows the "already complete" surface.

## Deviations from Plan

None — plan executed as written. The plan's expected gap-6 finding (mechanism ii) was confirmed by the Task 2 Step A investigation; the prescribed staleTime fix was applied. No architectural changes; no backend changes required.

## Issues Encountered

- **Pre-existing PWA lint errors (out of scope).** `pnpm lint` in `apps/pwa` reports 22 errors in `src/api/setupClient.contract.test.ts` (`no-unsafe-*`) and `src/routes/SetupPage.test.tsx:152` (`no-unused-vars`). Neither file was touched by this plan; both were last modified in earlier Phase-12 commits. The four files this plan touched lint clean (exit 0). Logged to `.planning/phases/12-initial-setup-wizard/deferred-items.md` and left untouched per the executor SCOPE BOUNDARY rule. Recommend a follow-up lint-cleanup quick task.

## Verification

- `apps/pwa` full suite: **258 tests passed (22 files)**; `App.test.tsx` 8 passed; `SetupBanner.test.tsx` 3 passed.
- `pnpm typecheck` (apps/pwa): clean.
- `grep -nE "alreadyLocked" apps/pwa/src/App.tsx` → `/setup` route gated on setupComplete (Surface 8).
- `grep` for new dismiss/X button in `SetupBanner.tsx` → none added (only contract comments).
- Touched-files lint: `eslint` over the 4 files → exit 0.

## Known Stubs

None.

## User Setup Required

None — no external service configuration required.

## Next Phase Readiness

- Both UAT major gaps (5 and 6) are closed in code with regression tests. Ready for re-UAT of the post-completion `/setup` surface and the post-wizard calendar banner.
- Remaining UAT gaps (if any from 12-05/12-06) are tracked in their own gap-closure plans; this plan scoped only gaps 5 & 6.
- Pre-existing PWA lint debt deferred (see deferred-items.md) — does not block this plan's UI behavior.

## Self-Check: PASSED

- All 5 created/modified files present on disk.
- All 3 commits (`fdcb4dc`, `2b3569f`, `96c4913`) present in git history.
