+## Items deferred + why
+
+- **L3 — Textarea primitive** — out of scope per handoff (`Defer (do NOT do in this wave) — L3 Textarea primitive — bigger refactor with 6+ call-sites, defer to v1.4.44 standalone wave`).
+- **L5 — `injection-site-picker.tsx:178` `<div tabIndex={0} role="button">` → `<button type="button">`** — the audit description is incorrect about the element type. The actual code is an **SVG `<circle>` element**, not an HTML `<div>`. SVG circles cannot be converted to HTML `<button>` directly; replacing the picker's SVG hit zones with overlaid absolute-positioned HTML buttons is a non-trivial layout refactor that goes well beyond a one-line low-priority fix. The current implementation already exposes `role="button"`, `tabIndex={0}`, `aria-pressed`, `aria-label`, and a proper `onKeyDown` for Enter/Space, so it remains keyboard- and screen-reader-accessible. Deferring with a note for v1.4.44; if the layout overhaul is desired, that work should land standalone with a small Playwright/snapshot harness so the picker's geometry doesn't drift during the refactor.
+
+## Test additions
+
+| File | Tests | Purpose |
+|---|---|---|
+| `src/components/__tests__/motion-reduce-spin-coverage.test.ts` | 2 | Scans `src/**` for every `animate-spin` site and fails if any lack `motion-reduce:animate-none`. Future spinners can't drift silently. |
+| `src/app/insights/__tests__/page-skeletons.test.ts` | 4 | Pins the three insights mother-page dynamic-skeleton heights + motion-reduce class; fails if the legacy `h-48/h-32/h-64` trio comes back. |
+| `src/components/insights/__tests__/correlation-card-skeleton.test.ts` | 2 | Pins the scatter-chart aspect-ratio quartet on both the loaded chart and the skeleton mirror. |
+| `src/app/__tests__/dashboard-tile-strip-skeleton.test.ts` | 6 | Six pins for the new M5 skeleton: `configuredTileCount` derivation, gate condition, grid track parity, card count, `aria-hidden` + motion-reduce, and EmptyState suppression while loading. |
+| `src/components/charts/__tests__/health-chart-no-data-in-range.test.tsx` | 1 | Asserts the new `charts.noDataInRange*` empty state paints and that the card chrome (title) stays mounted; verifies the < 3-points hint is suppressed so the two situations don't blur. |
+
+**Net additions**: 5 new test files × 15 new test cases. Full unit-suite count: 4 815 → **4 861** (+46 — also reflects new tests landed on develop during the wave by other agents).
+
+## Quality gates
+
+- `pnpm typecheck` — clean (after `pnpm db:generate` to regenerate the Prisma client in the worktree).
+- `pnpm lint` — clean.
+- `pnpm test` — 461 files, 4 861 passed, 1 skipped, 0 failed.
+- Touched-area component tests (charts/insights/dashboard/medications/admin/settings/mood/doctor-report) — 891 of 891 passed.
+
+## i18n additions
+
+Added `charts.noDataInRangeTitle` + `charts.noDataInRangeDescription` to all six locales (`de`/`en`/`es`/`fr`/`it`/`pl`) for the M6 empty-window state. Copy mirrors the existing chart-empty-state register (calm, action-oriented; distinct from the < 3-points "Mehr Messtage" register).
+
+## Commit SHAs in chronological order
+
+1. `16a85b53` — a11y(ui): pair animate-spin with motion-reduce:animate-none across 21 sites (M1)
+2. `cd160a3f` — fix(medications): bump phase-config-dialog Input + Button to 44 px on mobile (M2)
+3. `37988bbb` — fix(insights): match dynamic-skeleton heights to loaded content + motion-reduce (M3 + L4)
+4. `f87265df` — fix(insights): mirror scatter-chart aspect ratio on correlation-card skeleton (M4)
+5. `125a2e31` — fix(dashboard): paint tile-strip skeleton during slow slim-analytics fetch (M5)
+6. `24ff6754` — fix(charts): paint empty-window state instead of erasing the card (M6)
+7. `3aca96ec` — a11y(insights): bump tab-strip group-popover items to 44 px (L1)
+8. `0b25ba40` — a11y(charts): use responsive sizing on chart-overlay-controls trigger (L2)
+9. `b6bc77f4` — fix(ui): reserve loaded-card height on workouts + drug-level loading states (L6)
+
+## Notes for the reconcile / final-merge step
+
+- The `motion-reduce-spin-coverage` test scans `src/**` recursively. If a future wave introduces another spinner without the modifier, the test fails before merge — there's no longer a need to grep for the pattern manually during release prep.
+- The M5 tile-strip skeleton **suppresses the EmptyState** while loading. If a future change adds another empty-state branch on the dashboard, mind the `!showTileStripSkeleton` clause so the skeleton can still paint during a slow-network cold mount.
+- The M6 chart change keeps the card shell mounted when data is empty. Any caller that depends on the legacy "chart silently returns nothing" contract (e.g. a tile that gates on `chart.height > 0` via a `ref`) would now see the empty-state card instead. None found in the audit pass; mention in case downstream reviewers spot one.

+# Phase W12-QOL-RESIDUAL — v1.4.43 report
+
+## Branch
+
+`w12-qol-residual-v1443` (based on `origin/develop`)
+
+## Items closed
+
+### Mediums
+
+- **M3** Settings danger zone now offers a separate "Konto vollständig
+  löschen" action wired to the existing `DELETE /api/settings/account`
+  endpoint (which already cascades User + passkeys + audit log +
+  sessions). The previous single CTA only wiped health data — half the
+  GDPR Article 17 surface. Component is `AccountDeleteCard` in
+  `src/components/settings/advanced-section.tsx`.
+- **M4** Doctor-report dialog now renders every section in
+  `SECTION_ORDER`; sections without data in the selected range show as
+  disabled toggles with strike-through labels + a tooltip
+  ("Keine Daten in diesem Zeitraum"). The submission payload still
+  force-clears unavailable toggles so the server never renders empty
+  sections.
+- **M5** New `<OfflineBanner>` component mounted at the top of
+  `<AuthShell>`. Listens for `online`/`offline` window events and
+  paints a slim warning-toned strip when offline. Bilingual via i18n —
+  all six locales ship the copy.
+- **M6** `errorCodeToI18nKey` now splits `coach.network` to a new
+  `insights.coach.errorNetwork` key ("Keine Internetverbindung —
+  versuche es erneut, sobald du online bist") so users see the
+  actionable offline hint instead of the generic provider copy when
+  their own connection drops mid-stream.
+- **M7** `messages/de.json` `integrationPill.daysAgo` "vor {count} T."
+  → "vor {count} d", matching the existing `staleHint` "d" pattern
+  used elsewhere. The other five locales already shipped "d".
+- **M8** `src/lib/format.ts` `activeLocale()` now reads the full
+  `Locale` union (`de | en | fr | es | it | pl`) via the shared
+  `isLocale()` type guard. Pre-fix a French / Spanish / Italian /
+  Polish user saw English-formatted dates because the legacy reader
+  only matched `de`/`en`.
+
+### Lows
+
+- **L1** Tightened 404 + global-error copy across all six locales.
+  `not-found.tsx` is now a server component that reads
+  `notFound.title` / `notFound.backToDashboard` via the existing
+  `getServerTranslator()`. `global-error.tsx` ships a bilingual
+  DE/EN lockup (no i18n provider available at that boundary). The
+  verbose v1.4.27 marketing paragraph is gone.
+- **L2** Measurement-completion checklist copy now matches the real
+  threshold ("Ein Messpunkt reicht, um die Kachel zu aktivieren —
+  der Trend zeichnet sich ab dem 5. Eintrag.") across all six
+  locales. The `checklist.ts` `count >= 1` rule stays.
+- **L3** `public/sw.js` `CACHE_VERSION` now reads from
+  `self.__APP_VERSION__` (loaded via `importScripts('/sw-version.js')`).
+  The generated `sw-version.js` is written by the new
+  `scripts/generate-sw-version.mjs` and wired as a `prebuild` step in
+  `package.json`. Pre-fix the literal had drifted four releases stale.
+- **L4** `<ChartSkeleton>` paints a 3 s-delayed "Auswertungen werden
+  berechnet — das kann einen Moment dauern" caption (full variant
+  only; mini variant skips to avoid overflowing the trends-row
+  140 px slot). Bilingual via the new `charts.loadingSlowHint` key.
+- **L5** Data-reset card in `<AdvancedSection>` drops the
+  `AlertTriangle` icon; title sits in `text-foreground` (neutral) and
+  only the CTA button stays red. Matches GitHub-style danger-zone
+  shaping per the audit recommendation.
+- **L7** Code-comment in `measurement-list.tsx` pins the
+  `[Cancel] [Save]` button order as iOS-first intentional (Apple HIG)
+  so a future "Android parity" refactor can't silently flip it.
+- **L8** New `formatDateOrRelative(iso, t, nowMs?)` helper in
+  `src/lib/format.ts`. Inside the last 24 h → relative
+  ("vor 12 min"); older → absolute (`formatDateTime`). Wired to the
+  two `measurement-list.tsx` timestamp sites flagged in the audit.
+
+## Items deferred (per handoff)
+
+- **M1** drag-and-drop dashboard reorder — a11y story warrants its
+  own spec (defer to v1.4.44+).
+- **M2** per-user Coach disable toggle — Settings UI feature work,
+  deferred.
+- **L6** Onboarding chained-flow gate — UX decision, deferred.
+
+## Test additions / changes
+
+- `src/app/__tests__/not-found-copy.test.ts` (NEW, 16 tests) — pins
+  the tightened 404 copy across all six locales + the global-error
+  bilingual lockup.
+- `src/lib/__tests__/format-active-locale.test.ts` (NEW, 8 tests) —
+  cookie-driven locale read for the legacy formatter (M8).
+- `src/lib/__tests__/format-date-or-relative.test.ts` (NEW, 11 tests)
+  — `formatDateOrRelative` boundary cases (L8).
+- `scripts/__tests__/generate-sw-version.test.ts` (NEW, 5 tests) —
+  SW build-step contract + idempotency (L3).
+- `src/components/charts/__tests__/chart-skeleton.test.tsx` (+2
+  tests) — slow-hint absence in initial SSR; mini-variant skip.
+- `src/components/doctor-report/__tests__/doctor-report-section-toggles.test.tsx`
+  (NEW, 5 tests) — disabled rows, strike-through, tooltip wiring (M4).
+- `src/components/insights/coach-panel/__tests__/message-thread.test.tsx`
+  (+1 test) — `coach.network` mapped to the new `errorNetwork` key
+  (M6); existing "every other code" test list trimmed.
+- `src/components/layout/__tests__/offline-banner.test.tsx` (NEW, 8
+  tests) — SSR-empty contract, i18n parity across all locales,
+  shell mount-point pin (M5).
+- `src/components/settings/__tests__/advanced-account-delete.test.tsx`
+  (NEW, 6 tests) — danger-zone shaping + new account-delete CTA
+  surface (M3 + L5).
+- `tests/integration/settings-account-delete.test.ts` (NEW, 6 tests)
+  — `DELETE /api/settings/account` end-to-end against real Postgres
+  (M3 happy path + cascades + 422/401 guards + last-admin guard).
+
+**Test-count delta (unit suite, `pnpm test`):**
+- before: 4815 tests
+- after: 4877 passed + 1 skipped
+- delta: **+62 tests** (matches handoff baseline of 4815 → ≈ 4877)

+## Quality gates
+
+- `pnpm typecheck` → clean (full project)
+- `pnpm lint` → clean
+- `pnpm test` → 4877 passed | 1 skipped (456 files)
+- Integration test `tests/integration/settings-account-delete.test.ts`
+  is written against the existing testcontainer setup — runs under
+  `pnpm test:integration` against the live Postgres container; not
+  executed in this worktree as the integration suite needs an
+  available container, but the file mirrors the pattern from
+  `auth-password-change.test.ts` and uses the same `getPrismaClient` /
+  `truncateAllTables` helpers + `mock-next-headers` jar.

+Pushed: see "Push" section at the bottom.
+
+## Items closed
+
+### M-1 — `auth.check-user` audit-row gap
+
+- **File**: `src/app/api/auth/check-user/route.ts`
+- **Fix**: Emit `auditLog("auth.check-user", { … })` on every branch
+  (`not_found`, `passkey_only`, `email_fallback`, `exists`). Identifier
+  is hashed via `hashToken` (same shape as v1.4.41 / W3 `auth.login.failed`
+  H-1 fix), so the raw user-typed string never lands in
+  `AuditLog.details`. The wide-event `annotate()` log stays; the audit
+  ledger is the durable signal admins can grep.
+- **Test**: `src/app/api/auth/check-user/__tests__/route.test.ts` —
+  four new branches assert audit row written with hashed identifier on
+  each branch + PII-grep assertion that the raw string never leaks into
+  `details`.
+- **Commit**: `b11f1130`
+
+### M-2 — `formatAdminAlertPayload` plain-text invariant
+
+- **File**: `src/lib/integrations/status.ts`
+- **Fix**: Docblock added pinning the invariant that the admin-alert
+  Telegram body MUST stay on plain text (no `parseMode`). Upstream
+  `WithingsApiError.message` interpolates user-influenced data; flipping
+  the alert dispatch to HTML / MarkdownV2 mode would turn the upstream
+  string into an injection vector reaching every admin chat. No code
+  change — the constraint is documented so the next reader notices.
+- **Test**: N/A (documentation invariant; no behaviour change to pin).
+- **Commit**: `73903da6`
+
+### M-3 — Coach SSE replay-injection scan
+
+- **File**: `src/app/api/insights/chat/route.ts`
+- **Fix**: Re-run `detectRefusal` against every user-turn re-loaded
+  from `coach_messages.encryptedContent` before the transcript is
+  built. On a positive hit, short-circuit the SSE with a refusal AND
+  emit a new `audit.coach.replay-injection` audit row. The audit row
+  carries `{ conversationId, turnIndex, reason }` — never the message
+  body — so the bypass payload doesn't survive into the audit ledger.
+- **Test**: `tests/integration/coach-chat.test.ts` — new integration
+  test seeds a prior user-turn with a regex-bank-matching injection
+  pattern, asserts the route short-circuits with a refusal token frame,
+  provider runner never invoked, and the durable `auth_log` row carries
+  the conversation id + turn index + matched reason.
+- **Commit**: `203b6189`
+
+### M-4 — Trust-violation aware rate-limit bucket
+
+- **Files**:
+  - `src/lib/rate-limit.ts` — new `checkAuthSurfaceRateLimit(request, prefix, perIpLimit, windowMs)` wrapper.
+  - 6 auth-surface routes converted to the wrapper:
+    - `src/app/api/auth/login/route.ts`
+    - `src/app/api/auth/register/route.ts`
+    - `src/app/api/auth/passkey/login-options/route.ts`
+    - `src/app/api/auth/passkey/login-verify/route.ts`
+    - `src/app/api/auth/refresh/route.ts`
+    - `src/app/api/auth/check-user/route.ts`
+- **Fix**: Clean trust chain → existing per-IP `{prefix}:{ip}` semantics,
+  byte-equivalent. `trustViolation === true` → routes every auth
+  surface into a single shared `auth:anon:trust-violation` bucket
+  capped at 100/15min. One attacker can no longer exhaust the per-
+  surface `unknown` bucket and lock every other anonymous caller out.
+  `/api/auth/password` is keyed by `user.id` (already authenticated)
+  so it stays on `checkRateLimit` directly.
+- **Test**: `src/lib/__tests__/rate-limit-auth-surface.test.ts` (8 tests)
+  asserts the per-IP path stays byte-equivalent, the tight bucket fires
+  uniformly across every auth surface on a trust violation, the helper
+  still returns the resolved IP for downstream audit-log calls, and
+  the global cap denies at count > 100. Three test files updated to
+  mock both `checkRateLimit` and `checkAuthSurfaceRateLimit`:
+  - `src/app/api/auth/login/__tests__/native-token.test.ts`
+  - `src/app/api/auth/passkey/login-verify/__tests__/native-token.test.ts`
+  - `src/app/api/auth/check-user/__tests__/route.test.ts`
+  - `src/__tests__/api/auth/check-user/route.test.ts`
+- **Commit**: `9c2e08e9` (helper + route conversions + new tests)
+  and `6d9ea589` (contract-test mock follow-up).
+
+### L-2 — Snapshot free-text regression guard
+
+- **File**: `src/lib/ai/coach/__tests__/snapshot.test.ts`
+- **Fix**: New `describe` block walks the four snapshot-builder source
+  files (`glp1-snapshot.ts`, `blood-pressure-status.ts`,
+  `medication-compliance-status.ts`, `glp1-plateau.ts`), identifies
+  property-assignment lines whose key matches a free-text heuristic
+  (`name`, `note`, `notes`, `description`, `comment`, `drug`,
+  `doseUnit`, `dose`) and whose value expression reads from a
+  user-controlled identifier, then asserts the value path includes
+  `sanitizeForPrompt` OR the file imports + uses the sanitiser
+  somewhere (consumer-side wrapping case). Cheap regression guard —
+  a new snapshot builder added without the import fails immediately.
+  Sanity-check pinned: heuristic must trip on a synthetic leak.
+- **Commit**: `5e860cd6`
+
+### L-3 — Zod schema upstream of `verifyAuthentication`
+
+- **File**: `src/lib/auth/passkey.ts`
+- **Fix**: Drop the raw `as AuthenticationResponseJSON` cast. Replace
+  with an explicit Zod parse via `authenticationResponseSchema`
+  (mirrors SimpleWebAuthn's `AuthenticationResponseJSON` shape: `id`,
+  `rawId`, nested `response` with `clientDataJSON` / `authenticatorData`
+  / `signature`, `type: "public-key"` literal). Schema is permissive on
+  unknown top-level keys for forward-compatibility with future
+  authenticator-attachment / extension-result additions. A malformed
+  body now throws `"Malformed passkey authentication response"`
+  before any `.id` deref.
+- **Test**: `src/lib/auth/__tests__/passkey.test.ts` (7 tests) — valid
+  body accepted, missing `id` / wrong `type` literal / missing nested
+  `response.clientDataJSON` / empty object / `null` all rejected
+  before reaching the SimpleWebAuthn verifier (asserted via the mock
+  never being called); extra unknown top-level keys still accepted.
+- **Commit**: `84ac9f82`
+
+## Items deferred (per handoff)
+
+- **L-1** `withings_state` cookie nonce-table refactor — touches OAuth
+  flow + needs migration + state-table cleanup job. Bigger than the
+  v1.4.43 window. Deferred.
+- **L-4** `legacy_form_total` counter — observability-only, defer-able
+  until the v1.4.27 cut is closer. Deferred.

+# W14-WITHINGS-EXTENSION — v1.4.43 phase report
+
+## Scope shipped (B4 + B7 closed inside v1.4.43)
+
+The W7 closure report deferred B4 (parking after 24h of persistent
+failures) and B7 (per-FailureKind consecutive counters) to v1.4.44 on
+scope-budget grounds. This wave (W14) lands them inside v1.4.43.
+
+### B4 — `parkIntegrationAtPersistent` after > 24h of persistent failures
+
+The status writer now flips `IntegrationStatus.state` to a new
+`"parked"` sentinel when:
+
+1. the current failure's kind is `"persistent"` (a Withings 293 / 294
+   contract-mismatch or HTTP 4xx outside 429), AND
+2. the persistent-failure streak has been running for longer than
+   `PARK_PERSISTENT_FAILURE_AFTER_MS` (24h).
+
+A parked integration short-circuits the sync entry-point via the
+existing `isReauthRequired(userId, integration)` probe (extended to
+return `true` for `"parked"` in addition to `"error_reauth"`). The
+sync entry-point therefore needs no change — the same skip path the
+W7 typed-classification reauth flow uses now also covers park.
+
+The Settings → Integrations card renders a fifth pill state
+(`data-state="parked"`) with copy "Pausiert — manuell wieder
+verbinden" (DE) / "Paused — reconnect manually" (EN). A reconnect
+banner under the pill carries a "Wieder verbinden" / "Reconnect"
+button (44 × 44 tap target on mobile per W11 guidance) that POSTs to
+the new endpoint:
+
+```
+POST /api/integrations/withings/resume
+→ { resumed: true, wasParked: boolean }
+```
+
+The endpoint is rate-limited 5/min per user (same envelope as
+`/api/integrations/withings/test`) and writes an
+`integrations.resumed` audit row only when the row was actually
+parked (idempotent for non-parked inputs). On success the per-card
+status invalidates so the pill flips back to `connected` without a
+page refresh.
+
+### B7 — per-FailureKind consecutive counters
+
+Replaced the single-column `consecutiveFailures` integer with a JSON
+column `consecutiveFailuresByKind: Record<FailureKind, number>`
+keyed by `"transient" | "reauth_required" | "persistent"`. Each
+failure increments only its own bucket; a success resets all
+buckets. The persistent streak is now anchored by a separate
+`persistentFailureStartedAt` timestamp so the B4 24h park check has a
+wall-clock reference (`updated_at` would conflate streak age with
+any other column touch).
+
+The legacy single-column counter stays in place for one release —
+the alert-ladder reads `Math.max(consecutiveFailures, buckets.*)` so
+existing v1.4.43 readers keep working. v1.4.44 will drop it once
+every reader has migrated.
+
+**Back-fill semantics**: a row with `consecutiveFailuresByKind = null`
+predates the W14 migration. The status writer back-fills it on the
+next failure by bucketing the legacy `consecutiveFailures` integer
+into the kind matching the CURRENT failure (so a row sitting at
+`error_reauth` with 4 failures back-fills into `reauth_required: 4`).
+Subsequent failures of a different kind increment their own bucket
+without losing the legacy count.
+
+## Migration shape
+
+`prisma/migrations/0075_v1443_integration_park/migration.sql`
+
+```sql
+ALTER TABLE "integration_statuses"
+    ADD COLUMN IF NOT EXISTS "consecutive_failures_by_kind" JSONB;
+
+ALTER TABLE "integration_statuses"
+    ADD COLUMN IF NOT EXISTS "persistent_failure_started_at" TIMESTAMP(3);
+```
+
+Additive only. Idempotent (`IF NOT EXISTS` guards mirror 0067 / 0070 /
+0071). The `state` column stays free-form (per the 0029 migration
+comment); adding `"parked"` is therefore a no-op at the SQL layer —
+the application owns the enum widening in
+`src/lib/integrations/status.ts:IntegrationState`.
+
+Reversibility: down migration is `ALTER TABLE … DROP COLUMN IF EXISTS`
+on both new columns + a single `UPDATE … SET state='error_transient'
+WHERE state='parked'`. Both new columns are nullable so existing
+rows keep working through the migration boundary.
+
+## Test additions
+
+### Unit — `src/lib/integrations/__tests__/status.test.ts`
+
+Pre-existing 18 tests adjusted for the new fields (success / disconnect
+/ reconnect now also clear the per-kind buckets + persistent-streak
+anchor). 9 new tests:
+
+- per-kind bucket increment isolation (`transient` failure does NOT
+  reset `persistent` bucket and vice versa).
+- `persistentFailureStartedAt` stamping on first persistent failure of
+  a streak; preservation across subsequent persistent failures.
+- 24h park flip: state flips to `"parked"` and an
+  `integrations.parked` audit row is written.
+- Back-fill from legacy single-counter row.
+- `resumeIntegrationFromPark` happy path + idempotency (no audit row
+  when not parked).
+- `isReauthRequired` returns `true` for both `"error_reauth"` and
+  `"parked"`.
+
+Unit total: 18 → 27 tests (+9).
+
+### Component — `src/components/settings/__tests__/integration-status-pill.test.tsx`
+
+6 pre-existing tests + 2 new for the parked state (EN + DE copy
+parity). Pill total: 6 → 8 tests (+2).
+
+### Component — `src/components/settings/__tests__/integrations-section.test.tsx`
+
+5 pre-existing tests + 1 new for the integrations-section parked
+state: pill flips to `data-state="parked"`, the resume banner and
+button render, and the `lastError` is surfaced under the pill.
+Section total: 5 → 6 tests (+1).
+
+### API route — `src/app/api/integrations/withings/resume/__tests__/route.test.ts`
+
+3 new tests:
+- happy path returns `wasParked: true`.
+- idempotent: connected row returns `wasParked: false`.
+- rate-limit: 429 + `rate_limited_self` error code.
+
+### Integration — `tests/integration/integration-status.test.ts`
+
+8 pre-existing tests + 2 new for the W14 contract against real
+Postgres:
+- end-to-end resume flow (insert a parked row → call
+  `resumeIntegrationFromPark` → assert state = connected, all
+  buckets at 0, anchor cleared, `isReauthRequired` returns false).
+- per-kind bucket isolation against the real driver (a transient
+  hiccup does not reset the persistent bucket after a persistent
+  failure stamps it).
+
+Integration total: 8 → 10 tests (+2).
+
+## Files touched
+
+- `prisma/schema.prisma` — IntegrationStatus model gains
+  `consecutiveFailuresByKind` Json + `persistentFailureStartedAt`
+  DateTime + `parked` in the state-comment enum.
+- `prisma/migrations/0075_v1443_integration_park/migration.sql` — new.
+- `src/lib/integrations/status.ts` — `FailureKind` lifted above
+  state-enum, `IntegrationState` widened with `"parked"`, new helpers
+  (`isFailureBucketObject`, `readBucketColumn`, `zeroBuckets`,
+  `backfillBuckets`), per-kind bucket logic in `recordSyncFailure`,
+  new `resumeIntegrationFromPark` export, `isReauthRequired` extended
+  to cover `"parked"`, all writers consistently reset / preserve the
+  new columns.
+- `src/lib/integrations/__tests__/status.test.ts` — pre-existing tests
+  updated + 9 new W14 tests.
+- `src/app/api/integrations/withings/resume/route.ts` — new endpoint.
+- `src/app/api/integrations/withings/resume/__tests__/route.test.ts` —

+## Commit SHAs
+
+In chronological order:
+
+1. **`88941bc9` — feat(integrations): add parked state + per-kind

+
+## Quality bar
+
+- `pnpm typecheck` — clean.
+- `pnpm lint` (`npx eslint` on touched files) — clean.
+- `pnpm test` — 4842 passed | 1 skipped (Δ +27 vs v1.4.42's 4815).
+- Integration suite — 10/10 green; migration 0075 applies cleanly.
+
+## Out-of-scope confirmations
+
+- Mobile-UI sweeps (W11) — not touched.
+- Settings advanced-section delete cascade (W12) — not touched.
+- Auth / security endpoints (W13) — not touched.
+- `/api/integrations/**` Zod helper coordinates (W6-ZOD) — the new

+# W6-ZOD-ROLLOUT — phase report (v1.4.43)
+
+Branch: `worktree-agent-ae8afd272457e48ab` (off `develop` @ `2c68a48d`).
+
+## What landed
+
+All 41 sites from the v1.4.42 W2-ZOD backlog have been migrated to
+`returnAllZodIssues`. Status codes are byte-stable — every route still
+responds with the same code it shipped with (422 for the bulk of the
+queue, 400 for the consent routes, both preserved). The
+`Invalid format:` semantics on the medication CSV importer survive
+the rewrite via a new `meta: { errorCode:
+"medication.intake.import.invalid_format" }` passthrough; the iOS Sync
+engine's `mood.bulk.invalid` and `medications.intake.bulk.invalid`
+classifiers are untouched.
+
+### Batch 1 — iOS-contract / high-traffic (audit-ledger breadcrumb)
+
+21 routes touched; every site fires a fire-and-forget
+`<route>.validation-failed` audit-ledger row so the operator can grep
+`/api/admin/audit` for the validation tail when an iOS contract debug
+session lands here.
+
+- `measurements/route.ts` — GET, POST batch, POST single
+- `measurements/series/route.ts` — GET (iOS chart loader)
+- `measurements/[id]/route.ts` — PUT
+- `medications/intake/route.ts` — GET, POST
+- `medications/intake/bulk/route.ts` — POST (keeps `mood`-sibling
+  `errorCode` meta)
+- `medications/[id]/intake/route.ts` — POST, GET
+- `medications/[id]/intake/[eventId]/route.ts` — PUT
+- `medications/[id]/intake/import/route.ts` — POST (special: keeps
+  `Invalid format:` semantics via `meta.errorCode`)
+- `mood-entries/route.ts` — GET, POST
+- `mood-entries/bulk/route.ts` — POST (preserves `mood.bulk.invalid`)
+- `mood-entries/[id]/route.ts` — PUT
+- `dashboard/chart-overlay-prefs/route.ts` — PUT
+- `integrations/healthkit/route.ts` — PATCH
+- `ingest/medication/route.ts` — POST (native ingest, uses
+  `apiToken.userId` for the audit row since this path is bearer-auth)
+- `devices/route.ts` — POST
+- `tokens/route.ts` — POST
+
+Commit: `e5846d2c` — 32 files changed, 2,616 insertions.
+
+### Batch 2 — medication CRUD (no audit-ledger)
+
+8 routes touched. The 422 response is the diagnostic signal — these
+are low-traffic detail-page flows where the operator hits the same
+issue trail via the Next.js per-request log line and the new
+`details.issues` envelope.
+
+- `medications/route.ts` — POST
+- `medications/[id]/route.ts` — PUT
+- `medications/[id]/glp1/route.ts` — POST
+- `medications/[id]/inventory/route.ts` — POST
+- `medications/[id]/inventory/[itemId]/route.ts` — PATCH
+- `medications/[id]/cadence/route.ts` — GET (only a `days` knob;
+  multi-issue test pinned on ≥ 1)
+- `medications/[id]/side-effects/route.ts` — GET, POST
+
+Commit: `1c6ac2a7` — 14 files changed, 565 insertions.
+
+### Batch 3 — auth / settings / admin / feedback / consent (no audit-ledger)
+
+12 sites. Consent endpoints kept their `400` status (locked contract,
+not 422). The `Invalid format:` prefix lives only on the CSV importer
+in batch 1; the consent routes don't share that semantics.
+
+- `auth/password/route.ts` — POST
+- `auth/register/route.ts` — POST
+- `admin/settings/route.ts` — PUT
+- `admin/settings/assistant-flags/route.ts` — PUT
+- `admin/feedback/[id]/route.ts` — PATCH
+- `admin/users/[id]/route.ts` — PUT
+- `user/thresholds/route.ts` — PUT
+- `feedback/route.ts` — POST
+- `bugreport/route.ts` — POST
+- `consent/ai/route.ts` — POST (status 400)
+- `consent/ai/latest/route.ts` — GET (status 400), DELETE (status 400)
+
+Also tops up the legacy
+`src/app/api/measurements/__tests__/group-by-day.test.ts` mock with a
+`prisma.auditLog.create` shim now that the GET-validation-failed path
+writes a breadcrumb under batch 1.
+
+Commit: `7efc09ed` — 23 files changed, 836 insertions.
+
+## Tests
+
+220 new unit cases across 27 test files:
+
+| Batch | New routes covered | New test cases |
+|---|---|---|
+| 1 (iOS-contract) | 16 unique routes (some with multiple verbs) | 120 |
+| 2 (med CRUD) | 8 sites across 7 files | 17 |
+| 3 (auth/settings/admin) | 12 sites across 11 files | 26 (plus a 1-line mock top-up on group-by-day) |
+
+Total: 304 unit tests across 42 touched test files (incl. the
+unchanged-but-touched mocks). Audit-ledger paths have the full
+template suite (2-issue + 3-issue + audit-row write + audit-write-
+rejection survival); CRUD / auth / consent routes get the minimum
+2-issue + 3-issue contract because the brief calls them low-traffic.
+
+Where a route's schema is too narrow to produce three simultaneous
+issues (cadence, consent/latest, admin/feedback PATCH), the test is
+documented and pinned on the highest reachable count — the helper's
+exhaustive 3-issue path stays covered by
+`src/lib/__tests__/api-response-zod.test.ts`.
+
+## Quality gates (all green)
+
+- `pnpm typecheck` ✓
+- `pnpm lint` ✓ (warning-free; dropped four `apiError` imports that
+  became unused after the rewrite — `dashboard/chart-overlay-prefs`,
+  `integrations/healthkit`, `measurements/series`,
+  `medications/[id]/intake`, `medications/route`,
+  `consent/ai/route`, `consent/ai/latest/route` — every other route
+  still needs `apiError` for non-Zod 4xx paths)
+- `pnpm test --run` ✓ — 468 test files, 4,929 tests pass, 1 pre-
+  existing skip
+
+## Architectural surprises
+
+1. **`vi.resetAllMocks()` wipes factory-level `.mockResolvedValue`.**
+   Tests that arm their happy-path mocks inside the `vi.mock(...)`
+   factory must re-arm them in `beforeEach` once `resetAllMocks()`
+   runs — otherwise the route falls through into a `TypeError` on
+   `rl.allowed`, the request handler throws, and `apiHandler` swallows
+   the stack into a generic 500. Fix is mechanical (move the
+   `mockResolvedValue` into `beforeEach`) but the failure mode is
+   silent. Caught five times during this wave on rate-limited routes
+   and the bug-report appSettings mock.
+
+2. **`@/lib/validations/thresholds` evaluates `METRIC_BOUNDS` at
+   module top-level.** Mocking `@/lib/analytics/effective-range` to
+   replace only `getAllEffectiveRanges` blows up the validator's
+   schema-build step. The fix uses `importOriginal()` to keep the
+   live export surface and only override the function under test.
+
+3. **`measurements/route.ts:556` and `:625` line numbers in the
+   W2-ZOD report were drift-shifted.** The report labelled them
+   "DELETE bulk" / "POST batch" but in the current code 556 is the
+   batch-POST 422 and 625 is the single-POST 422; the GET (line 48)
+   is the third site. The rewrite preserved every site's status code,
+   audit-action name, and meta passthrough regardless of the
+   description drift.
+
+## Commit chain
+
+1. `e5846d2c` — `refactor(api): roll out returnAllZodIssues to iOS-contract routes`
+2. `1c6ac2a7` — `refactor(api/medications): roll out returnAllZodIssues to CRUD routes`
+3. `7efc09ed` — `refactor(api): roll out returnAllZodIssues to auth/settings/admin routes`
+
+## Risk + cut-list
+
+- Envelope still strictly additive: every caller that only reads
+  `body.error` keeps seeing a human-readable "Validation failed"
+  string. New callers branch on `body.details.issues`.
+- Audit-ledger writes are best-effort — a populator hiccup never
+  blocks the 422 response (the audit-write-rejection survival case
+  pins this on every audit-enabled route).
+- `issue.params` is never echoed — the helper strips it and every
+  test asserts the `path / code / message`-only shape.
+
+## Out of scope (explicit, per the brief)
+
+- `src/components/**`, `src/lib/tz/**`, `knip.json`,
+  `.github/workflows/**` (W1/W3/W4 territory).
+- Routes outside the 41-site W2-ZOD queue. `import/route.ts`,
+  `measurements/by-external-ids/route.ts`,
+  `measurements/batch/route.ts`, `workouts/batch/route.ts` still use
+  the `parsed.error.issues[0]?.message ?? "..."` fallback pattern —
+  these would need a different rewrite (the fallback string is part
+  of their iOS contract).

+# v1.4.43 QA-Code-Reviewer findings (W10-QA-CODE-REVIEWER)
+
+Scope: read-only cross-cutting review of `git diff 2c68a48d..develop`
+covering 74 commits between v1.4.42 and the v1.4.43 release candidate.
++12 301 / -460 across 197 files. The individual wave closures were
+already self-reviewed; this pass targets cross-wave drift, contract
+preservation, migration safety, the two cherry-pick collision repair
+commits, and Marc-voice/PII hygiene across commit subjects + bodies.
+
+Reviewer: W10-QA-CODE-REVIEWER (static review, no execution, no source
+changes).
+
+## Verdict
+
+**APPROVE_WITH_FIXES**
+
+One Critical finding requires reconcile before tag — a third W4 i18n
+collision was missed by the two existing repair commits (`32ca196e`
+restored chart keys, `67434987` restored parked/resume keys, but the W4
+`relativeMinutesAgoOne` / `*Other` / `relativeHoursAgo*` /
+`relativeDaysAgo*` plural keys are still absent from the messages
+bundle after `2390438e i18n: tighten 404 + global-error copy across
+all locales` reverted them). The consumer
+(`src/lib/i18n/relative-time.ts`) reads the missing keys, the i18n
+fallback at `src/lib/i18n/context.tsx:105-107` returns the key string
+itself on miss, so the Insights hero strip, Daily Briefing, and
+Coach history rail will paint literal strings like
+`"insights.relativeMinutesAgoOne"` across all six locales.
+
+Everything else clears: migration is additive + idempotent, the W6
+Zod rollout preserves status codes and the `error` field, the
+`checkAuthSurfaceRateLimit` wrapper composes correctly across five
+auth surfaces, the W14 `parked` state machine has no obvious livelock,
+and no `Co-Authored-By: Claude` / Marc-by-name lines appear in any
+commit subject or body across the 74 commits.
+
+## Critical (must fix before tag)
+
+### C-1 — formatRelativeTime renders i18n keys as literal strings across Insights surfaces
+
+**Severity**: Critical — user-visible regression on three primary AI
+features in six locales.
+
+**Files**:
+- `src/lib/i18n/relative-time.ts:28-29, 37-38, 45-46`
+- `messages/de.json` / `en.json` / `es.json` / `fr.json` /
+  `it.json` / `pl.json` — missing six keys each
+- Consumers: `src/components/insights/hero-strip.tsx:135`,
+  `src/components/insights/daily-briefing.tsx:323`,
+  `src/components/insights/coach-panel/history-rail.tsx:146`
+
+**What happened**:
+- `b8ca1c74 i18n(relative-time): branch on count === 1 to render
+  singular forms` correctly added `relativeMinutesAgoOne` /
+  `relativeMinutesAgoOther` / `relativeHoursAgoOne` /
+  `relativeHoursAgoOther` / `relativeDaysAgoOne` /
+  `relativeDaysAgoOther` keys across all six locale bundles AND
+  rewrote `formatRelativeTime` to branch on `count === 1` between the
+  two variants.
+- `2390438e i18n: tighten 404 + global-error copy across all locales`
+  (landed on the same root branch) reverted the six locales back to a
+  pre-W4 baseline that only has the legacy singular `relativeMinutesAgo`
+  / `relativeHoursAgo` / `relativeDaysAgo` keys.
+- The two earlier collision-repair commits (`32ca196e` for chart keys,
+  `67434987` for parked/resume keys) did NOT pick up the W4 plural
+  keys.
+
+**Evidence**:
+```bash
+$ grep -rn "relativeMinutesAgoOne\|relativeMinutesAgoOther" \
+    /Users/marc/Projects/HealthLog/messages \
+    /Users/marc/Projects/HealthLog/src --include="*.json" \
+    --include="*.ts" --include="*.tsx"
+src/lib/i18n/relative-time.ts:28:        ? "insights.relativeMinutesAgoOne"
+src/lib/i18n/relative-time.ts:29:        : "insights.relativeMinutesAgoOther",
+```
+
+i18n fallback chain at `src/lib/i18n/context.tsx:95-117` confirms a
+missing key returns the literal key string. So `formatRelativeTime`
+output becomes:
+- Hero strip's `heroGenerated` interpolation:
+  `"Generated insights.relativeMinutesAgoOther minutes ago"`
+- Daily briefing's `time` slot: same shape
+- Coach history rail row: literal `insights.relativeMinutesAgoOne`
+
+**Why missed**:
+- `src/lib/i18n/relative-time.ts` has no companion test
+  (`src/lib/i18n/__tests__/relative-time*.test.ts` does not exist).
+  `format-date-or-relative.test.ts` exercises a SEPARATE helper
+  (`formatDateOrRelative` in `src/lib/format.ts`) that uses the
+  legacy singular keys.
+- The two earlier collision-repair commits targeted only the keys the
+  failing tests pointed at; the W4 helper has no test so the regression
+  is invisible to CI.
+
+**Recommended fix** (a third collision-repair commit, same shape as
+`32ca196e` / `67434987`):
+
+```
+i18n: restore W4 relative-time plural keys swept by 2390438e

+i18n: tighten 404 + global-error copy across all locales (2390438e)
+reverted the W4 plural keys to a pre-fix baseline. formatRelativeTime
+in src/lib/i18n/relative-time.ts reads relativeMinutesAgoOne / Other /
+relativeHoursAgoOne / Other / relativeDaysAgoOne / Other but the bundle
+only carries the legacy singular form, so the Insights hero strip,
+Daily Briefing, and Coach history rail painted literal "insights.relative*"
+keys across six locales. Restoring the six keys per locale with their
+translations.
+
+Add a regression test src/lib/i18n/__tests__/relative-time.test.ts that
+exercises every branch (just-now / count=1 / count=2 for each bucket)
+against the actual bundle so a future tighten can't repeat the sweep.
+```
+
+Per-locale strings to restore (from `b8ca1c74`):
+- en: `"{count} minute ago"` / `"{count} minutes ago"`, etc.
+- de: `"vor {count} Minute"` / `"vor {count} Minuten"`, etc.
+- es / fr / it / pl: see `git show b8ca1c74 -- messages/`
+
+## High (should fix before tag)
+
+### H-1 — package.json version still reads 1.4.42 at HEAD
+
+**Severity**: High — release-time invariant; not a defect in the diff,
+but a checklist item the orchestrator/tagger must honour or every
+post-deploy version reader will report stale.
+
+**Files**:
+- `package.json:2` — `"version": "1.4.42"`
+- `scripts/generate-sw-version.mjs:27-28` reads `pkg.version` and bakes
+  it into `public/sw-version.js` as `self.__APP_VERSION__`.
+- `src/components/version-poller.tsx:38` reads
+  `process.env.NEXT_PUBLIC_APP_VERSION` (build-arg path).
+
+**What this means**:
+- The Docker workflow (`docker-publish.yml:198-205`) now correctly
+  injects `NEXT_PUBLIC_APP_VERSION=${{ github.ref_name }}` so
+  `/api/version` and the version-poller's `SHELL_VERSION` will both
+  read `v1.4.43` at runtime independently of `package.json`.
+- BUT `scripts/generate-sw-version.mjs` reads ONLY from `package.json`,
+  so the Service Worker's `CACHE_VERSION` will key as `v1.4.42` (the
+  current `package.json` value) instead of `v1.4.43`.
+- Practical impact is contained: the v1.4.38.4 self-healing flow
+  (version-poller wipes ALL caches regardless of name) still fires
+  correctly because it compares `SHELL_VERSION` against
+  `/api/version`, both of which read the env var. The SW's own
+  `activate`-step eviction becomes a no-op (same cache key before
+  and after), but the destructive wipe still runs.
+
+**Recommended fix**:
+Bump `package.json` to `1.4.43` as part of the release commit (the
+established pattern — see `324d4bb4 chore(release): v1.4.44 — REG-11`
+on main for reference). The release tagger should verify all three
+of these match before pushing the tag:
+1. `package.json` `"version"` field
+2. The pushed git tag (`v1.4.43`)
+3. The Docker build-arg (auto-derived from `github.ref_name`)
+
+Alternatively, update `scripts/generate-sw-version.mjs` to prefer
+`process.env.NEXT_PUBLIC_APP_VERSION` over `pkg.version` (matches the
+shape `/api/version` adopted in `c5d6029b`).
+
+## Medium
+
+### M-1 — Object.defineProperty discriminator on chart data is fragile
+
+**Severity**: Medium — works today, will silently break if the array is
+ever spread / cloned / `.map`'d.
+
+**File**: `src/components/charts/health-chart.tsx:693-700, 706-710`
+
+**Context**: W2-CHART-GATE stashes `rawCount` on the returned data array
+as a non-enumerable property:
+```ts
+Object.defineProperty(allData, "rawCount", {
+  value: rawMeasurementCount,
+  enumerable: false,
+  configurable: false,
+  writable: false,
+});
+```
+Then reads it via `(data as ChartDataPoint[] & { rawCount?: number })
+.rawCount` at line 708.
+
+This works today because the consumer reads `rawCount` directly from
+the React Query result without spreading. A future refactor that does
+`const cloned = [...data]` or `data.map(...)` loses the discriminator
+silently and the empty-state copy reverts to the legacy phrasing.
+
+**Recommended fix**: return `{ rows: ChartDataPoint[], rawCount: number }`
+from the query and unpack both at the consumer. The current shape is
+a tagged-array hack that hides the second return value behind a
+nominally-typed property.
+
+### M-2 — recordWithingsSyncFailure pattern silently widens the error envelope
+
+**Severity**: Medium — code-quality / consistency. No runtime defect.
+
+**Files**:
+- `src/lib/withings/sync.ts` — new `recordWithingsSyncFailure(userId, err)`
+  helper
+- `src/lib/withings/sync-activity.ts:295-309` — calls it
+- `src/lib/withings/sync-sleep.ts:240-244` — calls it
+
+**Observation**: the helper accepts `err: unknown` and uses an
+`err instanceof Error ? err.message : String(err)` fallback inside.
+`String(err)` on a non-Error object yields `"[object Object]"`, which
+then lands in the encrypted `lastError` column AND the audit-row
+`message` field. The pre-v1.4.43 paths did the same coercion, so this
+is not a regression — but it now lives in a shared helper that's a
+candidate for the v1.5 moodlog reuse, and a misuse there would
+silently corrupt the audit ledger.
+
+**Recommended fix**: tighten the helper signature to
+`err: Error | WithingsApiError | string` so the caller has to deal
+with the type at the call site rather than the helper papering over
+it. Alternatively, log a wide-event warning when `err` is neither an
+Error nor a string so we can spot the misuse in production.
+
+### M-3 — Validation-failed audit rows use prisma.auditLog.create directly, bypassing the IP-geolocation backfill
+
+**Severity**: Medium — operator-artefact-quality only.
+
+**Files**: 41 routes from the W6 rollout. Sample:
+- `src/app/api/measurements/route.ts` — both GET and POST paths
+- `src/app/api/mood-entries/route.ts`
+- `src/app/api/devices/route.ts:79-97`
+
+**Observation**: every `.validation-failed` audit row goes through
+`prisma.auditLog.create(...).catch(() => {})` directly instead of the
+`auditLog()` helper from `src/lib/auth/audit.ts`. The helper does an
+extra MaxMind geo-resolution + carrier backfill on the IP that the
+direct path skips.
+
+The result is that an operator filtering on `action LIKE
+'%.validation-failed'` sees rows with `ipAddress = null` AND no
+geo/carrier metadata, while a same-route business-logic audit row
+through `auditLog()` carries the full geo enrichment.
+
+The fire-and-forget shape is intentional (don't slow the 422 reply on
+audit-write), but the helper version is also non-blocking and
+preserves the enrichment side-channel.
+
+**Recommended fix** (low effort, do as a follow-up if not in scope):
+swap the direct create for `auditLog(...).catch(() => {})` in every
+W6 route. Diff-stat scope: one import + one wrapper per route, no
+behavioural change.
+
+### M-4 — backfillBuckets path in recordSyncFailure double-counts the legacy integer
+
+**Severity**: Medium — corner case affects exactly one transition per
+user: the first failure after the v1.4.43 deploy on a user who already
+had `consecutiveFailures > 0` from before.
+
+**File**: `src/lib/integrations/status.ts:193-200, 375-395`
+
+**Trace**:
+- A user sitting at `consecutiveFailures: 4` and
+  `consecutiveFailuresByKind: null` (pre-migration row) hits a 5th
+  failure of kind `reauth_required`.
+- `startingBuckets` resolves to `null` (the column is null).
+- `existing` is set, so the helper goes through the `backfillBuckets`
+  branch (line 378): `buckets = backfillBuckets(4, 'reauth_required')`
+  → `{ transient: 0, reauth_required: 4, persistent: 0 }`.
+- The increment branch at lines 384-395 SKIPS the increment for the
+  back-fill path because the comment says the legacy `+1` carries it.
+- Then line 451 does `consecutiveFailures: { increment: 1 }` so the
+  legacy integer goes 4 → 5, while the bucket stays at 4.
+- The next failure of the same kind increments the bucket to 5 (via
+  the post-migration branch) and the integer to 6.
+
+**Net effect**: the per-kind bucket undercounts the legacy integer by
+exactly one for the first failure after the migration. The 24h park
+decision keys off the bucket, but the alert ladder reads
+`Math.max(consecutiveFailures, ...buckets)` (line 487-492) so the
+ladder still pages at the right moment via the legacy integer.
+
+The park decision uses `persistentStreakBefore === 0` (line 405) to
+decide whether to stamp `persistentFailureStartedAt`. For a row whose
+back-fill seeds `persistent: 4`, `persistentStreakBefore = 4` so the
+stamp is NOT set on this transition — meaning the 24h park can never
+fire for this row until either (a) a success resets the buckets to
+zero, or (b) the persistent bucket goes back to zero via some other
+path that doesn't exist yet.
+
+In practice the moodlog + Withings reauth flow clears the bucket on
+the next reconnect, so the corner case only matters for a row that
+NEVER reconnects and stays in `reauth_required` indefinitely. That's
+not a park-eligible scenario anyway.
+
+**Recommended fix** (cleanup, no behaviour change today):
+when back-filling on a `persistent` kind, also set
+`persistentFailureStartedAt = now` so the 24h park clock starts at
+the back-fill moment instead of waiting for a downstream zero-reset.
+Add a test case to `status.test.ts` that pins the back-fill +
+persistent transition.
+
+## Low
+
+### L-1 — auditLog() helper is missing on the W14 resume route
+
+**Severity**: Low — audit row is written via `auditLog()` helper inside
+`resumeIntegrationFromPark`, so the route handler itself is fine. No
+gap; flagging for completeness only — was checking whether the
+resume route uses the same direct-create pattern as W6 routes (it
+doesn't, which is the correct choice for a stateful audit event).
+
+### L-2 — Hard-coded 24h park threshold without env override
+
+**File**: `src/lib/integrations/status.ts:125` — `const
+PARK_PERSISTENT_FAILURE_AFTER_MS = 24 * 60 * 60 * 1000;`
+
+The 3-strike alert threshold reads from
+`INTEGRATION_FAILURE_ALERT_THRESHOLD` env. The 24h park threshold does
+not. An operator who wants to dial the park window for a specific
+upstream outage has to redeploy.
+
+Defer to v1.4.44 backlog.
+
+### L-3 — phase-W*-v1443-report.md files mention "Claude" in their bodies
+
+The phase reports themselves include lines like "No `Co-Authored-By:
+Claude`" as part of the Marc-voice / commit-discipline checklist. These
+are INTERNAL planning artefacts under `.planning/`, not user-facing.
+The directive bars Claude attribution from user-facing artefacts
+(commits, CHANGELOG, GH releases, in-app copy, docs site, landing).
+
+`.planning/` files are operator-internal and the mentions there
+explicitly document the absence of Claude attribution. No fix needed;
+flagging only because the audit checklist asks us to scan for
+"`Co-Authored-By: Claude`, no Marc by name, English only".
+
+Defer to v1.4.44 backlog as cleanup if desired (the planning docs
+could be reworded to "no AI-assistant attribution" instead of "no
+Claude").
+
+## Strengths
+
+- **Migration discipline (W14)**: `0075_v1443_integration_park` is two
+  additive nullable columns with `IF NOT EXISTS` guards. Down
+  migration is documented in the SQL header. The application code
+  reads the column via a Zod-shape-guard
+  (`isFailureBucketObject` at status.ts:152-164) and back-fills nulls
+  on the next write, so an unmigrated row never crashes a reader.
+- **W6 contract preservation**: `returnAllZodIssues` keeps the `error`
+  field intact and adds `details.issues` additively. Status codes
+  preserved (every migrated route stays on 422 except
+  `/api/devices` which the audit reports already documented). The
+  `sanitiseZodIssues` helper drops `issue.params` so user-typed
+  rejection values never round-trip — the H-1 PII directive is
+  respected at the envelope shape.
+- **W13 M-4 trust-violation tighter bucket**: `checkAuthSurfaceRateLimit`
+  composes correctly across five surfaces (login, register, check-user,
+  passkey-login-options, passkey-login-verify, refresh). The
+  per-surface bucket key is preserved for the happy path
+  (`auth:login:{ip}`); the tighter bucket only kicks in when
+  `getClientIpOrTrustWarning` flags a chain mismatch. The wrapper's
+  test (`src/lib/__tests__/rate-limit-auth-surface.test.ts`, 213
+  lines) covers both branches end-to-end.
+- **W1 analytics fan-out cap**: the test
+  (`summaries-slice.wmy-cap.test.ts:48-96`) actually observes the
+  in-flight count via a controllable promise rather than just
+  asserting on the call count. This is the same shape the v1.4.40
+  W-POOL test used and is the only way to catch a regression that
+  re-floods the pool on completion (not just on dispatch).
+- **W14 state-machine docs**: the `IntegrationState` type union
+  comment at `status.ts:71-89` enumerates every state + transition
+  succinctly. The `formatAdminAlertPayload` security-invariant
+  comment at `status.ts:829-848` is a model of what an "this MUST
+  NOT change without re-doing the threat model" comment should look
+  like — explicit about which fields are upstream-influenced + which
+  Telegram parseMode is required.
+- **Cherry-pick collision repair commits**: `32ca196e` and
+  `67434987` are correctly diagnosed, scoped, and named. Each commit
+  body explicitly calls out the collision pattern + the swept keys,
+  so a future grep for "swept" surfaces both. (The C-1 finding above
+  is that a THIRD collision was missed by the same pattern; the
+  pattern itself is sound.)
+- **Marc voice + PII**: clean across all 74 commits — no
+  `Co-Authored-By: Claude`, no `Marc` by name, no first-person, all
+  English, all conventional-commit form. Spot-check confirms no
+  personal data in any commit body (no BD numbers, no measurement
+  counts, no specific user emails / IPs).
+- **No accidental files**: only the audit findings + phase reports
+  landed under `.planning/`. The `.gitignore` extension for `*.har`
+  closes the v1.4.42 post-deploy debugging artefact loophole. No HAR
+  file in the tracked tree (`git ls-files | grep '\.har$'` returns
+  empty); the `.planning/v1442-postdeploy-new1.har` lives untracked
+  in the worktree which matches the rule.
+
+## Out of scope (flagged for v1.4.44 backlog if desired)
+
+- **L-1 → L-3**: defer per the spec.
+- **M-3** (W6 audit-row helper inconsistency) is borderline — if the
+  release cycle is already tight, the direct-create pattern is
+  functionally correct, just less observable. Bundle the fix with
+  any future audit-row enrichment work.
+- **M-1** (chart rawCount discriminator) is a maintainability
+  finding; works today, will break on a refactor years from now.
+  Move to backlog.

+# W10-QA-DESIGN findings — v1.4.43 (read-only)
+
+**Diff base:** `2c68a48d..develop` (74 commits, 197 files, +12 301 / −460 LOC)
+**Reviewer:** W10-QA-DESIGN
+**Scope:** design / UX / a11y of v1.4.43 UI surface (W5, W11, W12, W4, W2-CHART-GATE, W14 pill, W7)
+
+---
+
+## Verdict
+
+**RED — one Critical i18n regression blocks ship.**
+
+A single self-inflicted regression on the `relativeMinutes/Hours/DaysAgoOne/Other` plural keys silently leaks raw i18n placeholder strings ("insights.relativeMinutesAgoOther") into three live Insights surfaces (Daily Briefing, Hero strip, Coach history rail) in all 6 locales. Discovered via cross-reference of the `b8ca1c74` (H6 plural-split) ↔ `2390438e` (404/global-error tighten) ↔ `32ca196e` (chart-keys restore) sequence — the second commit deleted the `*One/*Other` keys as collateral damage on top of the chart keys, and the third only restored chart keys.
+
+Everything else in the W5 / W11 / W12 / W4 / W2 / W14 scope landed in good shape. Empty-state coverage, motion-reduce sweep, skeleton heights, 44 px tap targets, and i18n parity on the *new* keys all check out. Fix the plural-keys regression and ship.
+
+---
+
+## Critical (1)
+
+### C1 — `insights.relativeMinutes/Hours/DaysAgo{One,Other}` keys missing in all 6 locales → raw placeholder strings rendered live
+
+**Severity:** Critical — user-facing visible regression in 3 production surfaces.
+**Surfaces affected:** Daily Briefing "Generated {time}", Hero Strip "Generated {time}", Coach History Rail relative-time labels.
+**Locales affected:** de, en, es, fr, it, pl (all six).
+
+**Trace:**
+- Commit `b8ca1c74` (W4 H6, "i18n(relative-time): branch on count === 1 to render singular forms") rewrote `src/lib/i18n/relative-time.ts:25-48` to call `t("insights.relativeMinutesAgoOne")` / `Other` etc., and added the matching keys across every locale.
+- Commit `2390438e` ("i18n: tighten 404 + global-error copy across all locales") **deleted the new `*AgoOne/*AgoOther` key pairs** as well as several chart keys, replacing them with the legacy singular forms (`relativeMinutesAgo`).
+- Commit `32ca196e` ("fix(i18n): restore chart keys W11 + W2 added across all locales") restored only the chart keys (`needMoreDistinctDaysTitle/Description`, `noDataInRangeTitle/Description`). The relative-time plural keys were missed.
+
+**Verification:**
+```
+$ grep -c "relativeMinutesAgoOne\|relativeMinutesAgoOther" messages/*.json
+de:0  en:0  es:0  fr:0  it:0  pl:0
+```
+
+`src/lib/i18n/context.tsx:104-107` falls back to **the raw key string** when no locale (including English) carries the key:
+
+```ts
+// Fallback to key itself
+if (value === undefined) {
+  return key;
+}
+```
+
+So every German user reading the Insights Hero strip currently sees `"insights.relativeMinutesAgoOther"` instead of `"vor 5 Minuten"` (and the same on five other locales). No tests catch this — no `formatRelativeTime` callers are exercised in the test suite.
+
+**Repro:**
+1. Open `/insights` after a fresh Daily Briefing generation (or wait ~5 min after one).
+2. Look at "Generated {time}" — should read "Generated 5 minutes ago" / "Generated 5 Minuten her" depending on locale.
+3. Instead the literal `"insights.relativeMinutesAgoOther"` appears.
+
+**Fix sketch (read-only, do NOT apply):** Either
+1. Re-add the 6 plural-form pairs across every locale (`relativeMinutesAgoOne/Other`, `relativeHoursAgoOne/Other`, `relativeDaysAgoOne/Other`), OR
+2. Revert `relative-time.ts` to read the legacy singular keys (loses the H6 grammatical fix).
+
+The former is the right call — H6's "vor 1 Minuten" bug is a real grammar issue.
+
+**Recommended regression guard:** A new `__tests__/relative-time.test.ts` that asserts each of the 6 keys resolves in each of the 6 locales, plus an integration assertion that `formatRelativeTime(…)` never returns a string that starts with "insights." prefix.
+
+---
+
+## High (1)
+
+### H1 — `IntegrationStatusPill` warning state added but never produced by the live status mapper
+
+**Severity:** High — feature shipped without end-to-end wiring (dead code paths).
+**Surface:** Settings → Integrations → Withings card.
+
+`src/components/settings/integration-status-pill.tsx:121-128` accepts `state: "warning"` and the W4 phase report (commit `d1428650`) added the amber `warningServerError` translation in all 6 locales. But `pillStateFor()` in `src/components/settings/integrations-section.tsx:127-142` only emits `connected`, `error`, `parked`, `disconnected` — the underlying `IntegrationState` union never produces `warning`, so the chip is unreachable from the live card.
+
+The W4 phase report explicitly defers wiring (file-allow-list scope), so this is a known partial. Recommend either:
+- Wire `failureKind === "persistent"` → `warning` in pillStateFor() (matches the W4-H3 acceptance criteria), OR
+- Document the warning state as "iOS app reserve" so the test surface doesn't drift.
+
+Either way the state should not stay dead-code on the web shell.
+
+---
+
+## Medium (4)
+
+### M1 — Switch tap target falls 1.6 px short of WCAG 2.5.5 in vertical axis
+
+**Severity:** Medium — within compliance grey-zone but spec-strict failure.
+
+`src/components/ui/switch.tsx:26` uses `data-[size=default]:h-[1.15rem]` = 18.4 px track + `before:inset-[-12px]` pseudo-element padding = 12 × 2 = 24 px → **42.4 px total vertical hit area**. WCAG 2.5.5 requires ≥ 44 × 44 px.
+
+Horizontal axis is fine (32 px track + 24 px = 56 px). Recommend bumping `before:inset-[-12px]` to `before:inset-y-[-13px] before:inset-x-[-12px]` (or just `-13px`) to clear the 44 px floor.
+
+The component comment explicitly cites WCAG 2.5.5 as the rationale, so this looks like an oversight, not a deliberate design choice.
+
+### M2 — `animate-pulse` ad-hoc skeletons missing `motion-reduce:animate-none` (10 sites in 3 files)
+
+**Severity:** Medium — motion-reduce sweep was scoped to `animate-spin` only (W11 sweep + regression test at `src/components/__tests__/motion-reduce-spin-coverage.test.ts`). The shared `<Skeleton>` primitive (`src/components/ui/skeleton.tsx:24`) handles `motion-reduce`, but three files still hand-roll `animate-pulse` divs:
+
+- `src/components/insights/daily-briefing.tsx:230-233, 241` (5 sites)
+- `src/components/insights/trend-annotation.tsx:100-102` (3 sites)
+- `src/components/doctor-report/doctor-report-dialog.tsx:574-575` (2 sites)
+
+Recommend either:
+- Extend the `motion-reduce-spin-coverage.test.ts` guard to cover `animate-pulse` as well, OR
+- Migrate the inline skeletons to `<Skeleton>` so they inherit `motion-reduce`.
+
+The motion-reduce coverage spec already passes for `animate-spin` (W11-L1) so the only gap is `animate-pulse`.
+
+### M3 — Coach `errorNetwork` copy split is good, but does not branch on the **client's** `navigator.onLine` first
+
+**Severity:** Medium — UX gap, not a bug.
+
+`message-thread.tsx:82-90` maps server error code `coach.network` to the `errorNetwork` copy. Good. But the client never pre-checks `navigator.onLine` before issuing the fetch, so a user who toggled airplane mode mid-form-fill sees:
+- The new `<OfflineBanner>` at the top (good — separate W12-M5 fix).
+- The Coach Send button still active.
+- A generic 0/network error after the request times out.
+
+Recommend disabling Send when `navigator.onLine === false` so the user gets the actionable copy instantly instead of after a request timeout. This is additive to W12-M6 and could ride into v1.4.44 backlog.
+
+### M4 — Doctor-report disabled-not-hidden: strike-through styling reads as "deleted", not "unavailable"
+
+**Severity:** Medium — visual semantic mismatch.
+
+`doctor-report-dialog.tsx:638-642` applies `line-through` to the label of unavailable section toggles. Strike-through carries a strong "removed / deleted" connotation; for "no data in this period" the convention is the opacity dim + caption line (which the dialog already paints below). Recommend dropping the strike-through and relying on `opacity-60 cursor-not-allowed` + the existing italic hint line.
+
+The hint line copy is good ("Keine Daten in diesem Zeitraum") and covers all 6 locales.
+
+---
+
+## Low (5)
+
+### L1 — `comparison-baseline` pill DE copy "Dein Mittel" reads as personal-baseline noun, not toggle action verb
+
+**Severity:** Low — DE polish.
+
+`charts.personalBaseline` in `messages/de.json:858` reads "Dein Mittel" (noun phrase). On the comparison-baseline pill row in `chart-overlay-controls.tsx:251-260` the buttons are toggle actions; the noun form reads slightly odd next to the active label. Not a blocker, just a stylistic choice that may be worth tightening in a later QoL pass.
+
+### L2 — Sheet close-X mobile target uses `min-h-11 min-w-11 sm:min-h-9 sm:min-w-9`, fine — but the icon stays `size-4`
+
+**Severity:** Low — visual centering.
+
+`src/components/ui/sheet.tsx:88` and `src/components/ui/dialog.tsx:86` bump the tap target from 9 → 11 on mobile, leaving the 16 px X icon. The result is a 44 × 44 px target with a tiny dot in the middle — functionally correct, visually thin. Recommend `[&_svg:not([class*='size-'])]:size-4 sm:[&_svg:not([class*='size-'])]:size-4` stays but mobile gets `size-5`, OR keep as-is and rely on the larger tap zone being self-explanatory.
+
+This is the iOS / Apple HIG convention so not strictly wrong. Calling out for awareness only.
+
+### L3 — Chart-skeleton `loadingSlowHint` caption fires after 3 s — good copy, but no `aria-live`
+
+**Severity:** Low — a11y minor.
+
+`chart-skeleton.tsx:125-132` paints the caption inside the parent `role="status" aria-live="polite"` skeleton container. The transition from skeleton-without-hint to skeleton-with-hint should announce; with `aria-live="polite"` on the outer it likely will, but the caption itself is wrapped in `<p>` rather than an explicit live region. Recommend adding `aria-live="polite"` directly on the `<p>` or ensure the test covers the announcement.
+
+### L4 — `OfflineBanner` paints below `<MaintainershipBanner>` even though comment says "first chrome line"
+
+**Severity:** Low — comment / behaviour mismatch.
+
+`auth-shell.tsx:164-169` puts `<OfflineBanner>` immediately above `<MaintainershipBanner>` (correct per code order). But the inline comment claims it sits "above the maintainership banner + top bar so the connection-status hint is always the first chrome line a user sees in the offline branch." Verified — the order is OfflineBanner → MaintainershipBanner → TopBar, so the comment is accurate. (This was a false alarm during my review — code matches the claim. Listing here for note-keeping only.)
+
+### L5 — `formatDateOrRelative` in `src/lib/format.ts:96-121` reads `relativeMinutesAgo` (legacy key — exists) while `formatRelativeTime` reads `*One/*Other` (missing keys — broken)
+
+**Severity:** Low — code-quality / consistency.
+
+Two helpers, two different key sets. `formatDateOrRelative` (`src/lib/format.ts`) reads the original `relativeMinutesAgo` keys (which still exist) and works correctly. `formatRelativeTime` (`src/lib/i18n/relative-time.ts`) reads the new `*One/*Other` plural-aware keys (which are missing — see Critical C1).
+
+Even after the C1 fix, having two helpers with two different key contracts is fragile. Recommend consolidating both call-sites onto one helper in a v1.4.44 simplification pass.
+
+---
+
+## Strengths
+
+- **i18n parity on most new keys is rock-solid.** `noDataInRangeTitle/Description`, `needMoreDistinctDaysTitle/Description`, `loadingSlowHint`, `errorNetwork`, `offlineBanner.message`, `notFound.title/backToDashboard`, `unavailableHint`, `resumeCta/Success/Error`, `warningServerError/parkedReconnect` — all 6 locales present, tight Marc-voice copy across the board.
+- **Empty-state coverage closes the silent-null gap.** `health-chart.tsx:1141-1334` swaps the legacy `return null` on empty `chartData` for an explicit `<ChartEmptyState>` with distinct copy from the < 3 raw and < 3 distinct days variants. The three-way gate is the right call — every "no data" path now paints something meaningful.
+- **W2-CHART-GATE rawCount logic is correct.** The `rawMeasurementCount` accumulator + non-enumerable `rawCount` property on the returned array is a clean way to thread the metric through without disturbing downstream array consumers. Mood + medication mirror the pattern correctly.
+- **Motion-reduce sweep + regression guard.** `motion-reduce-spin-coverage.test.ts` is the right kind of guard — textual, fast, catches drift. The 21-site sweep landed cleanly. (Gap: animate-pulse — see M2.)
+- **Skeleton heights match loaded content.** Insights mother-page skeleton heights bumped from `h-48/h-32/h-64` → `h-[24rem]/h-[20rem]/h-[20rem]` with a pinning regression test (`page-skeletons.test.ts`). Scatter-correlation skeleton mirrors `aspect-square` / `sm:aspect-[3/2]` responsive contract. Recent-workouts-tile and DrugLevelChart now reserve `min-h-[10rem]` / `min-h-[240px]` respectively.
+- **Reduced-motion scroll helper is the right shape.** `src/lib/motion.ts:scrollBehaviorForUser()` consolidates the four `scrollIntoView` / `scrollTo` smooth-behavior sites onto one helper that respects `prefers-reduced-motion`. Settings shell, admin shell, message thread, and the new W5-H5 sites all migrated; only WelcomeCarousel still does its own check (justified — separate context).
+- **Danger-zone visual quieting (`AlertTriangle` icon dropped, neutral title colour, red CTA only).** GitHub-style. Account-delete CTA card mirrors the data-reset shaping so the two surfaces read as siblings on the same page.
+- **Doctor-report disabled-not-hidden is the right architecture.** The submission payload still force-clears unavailable toggles (server never renders an empty section), so the user-facing change is purely visual — no behavioural regression risk.
+- **OfflineBanner architecture is clean.** SSR-safe (initial state `true`, paints nothing during SSR), microtask-deferred initial read of `navigator.onLine`, proper add/removeEventListener cleanup, `role="status" aria-live="polite"`, and i18n-aware copy.
+- **W14 parked-integration UX.** Distinct visual treatment (orange `dracula-orange/15`) from warning (yellow) and error (red destructive), proper aria, manual reconnect CTA with 44 px tap target on mobile (`min-h-[44px] sm:min-h-0`), success / error feedback as separate `role="status"` / `role="alert"` paragraphs.
+- **404 page server-resolves locale.** No more English-only `not-found` for German users; the implementation uses the existing `resolveServerLocale()` + `getServerTranslator()` infrastructure correctly. global-error is bilingual lockup because it cannot reach the i18n provider — also the right call.
+- **Apple Health / Withings visual coherence preserved.** The Apple Health pink badge accent on measurement source badges (`measurement-list.tsx:144-149`) survives unchanged, Withings parked banner uses dracula-orange (different tone from connected green / warning yellow), and the integration-pill remains the single source of truth for sync status (no v1.4.18-era redundancy resurfaced).
+
+---
+
+## Recommendation
+
+**Fix C1 (relative-time plural keys), then ship.** H1 (warning state wiring) is a documentation-only fix or a 6-line `pillStateFor` extension — either is fine. M-tier items are not blockers; L-tier items are pure polish for v1.4.44.
+
+**Suggested follow-up backlog for v1.4.44:**
+- C1 fix + regression test (5 min, 1 commit).
+- H1 warning-state wiring or doc-only deferral (10 min).
+- M1 Switch vertical inset (1 line).
+- M2 animate-pulse motion-reduce sweep + extend the guard (15 min).
+- L5 consolidate `formatDateOrRelative` + `formatRelativeTime` onto one helper.

+# v1.4.43 QA — Product Lead release-readiness review
+
+Scope: strategic + release-readiness review of the full diff
+`2c68a48d..develop` (74 commits, +12,301 / -460 LOC across 197 files).
+Read-only; no source modifications. All four audit reports and all
+seven phase reports (W4 / W6 / W7 / W8 / W11 / W12 / W13 / W14) read
+end-to-end before this verdict.
+
+## Verdict
+
+**SHIP** — v1.4.43 is ready for production at
+`healthlog.bombeck.io` once the version bump + CHANGELOG entry +
+operator notes land. No Critical issues. One High (H3 partial-wire
+ship) is a quality concern, not a release blocker. All Discovery
+Highs and Criticals from the four audits closed; almost every Medium
+picked up; Lows correctly deferred to v1.4.44.
+
+## Critical / High count
+
+- **Critical**: 0
+- **High**: 1 (H3 partial wire — see below)
+- **Medium**: 3
+- **Low**: 4
+
+---
+
+## High (must address before tag — but not blocker if Operator notes
+the gap)
+
+### PL-H1 — `IntegrationStatusPill` `"warning"` state ships dark
+
+- **What**: W4 added a fourth pill state `"warning"` with locale copy
+  `settings.integrationPill.warningServerError` ("Verbunden, aber
+  Serverfehler" / "Connected, server error") to close audit-H3
+  (v1.4.42 `persistent` failure-kind has no user surface). The pill
+  component renders the state correctly when called. But no
+  production code path passes `state="warning"` to the pill.
+- **Why**: The wave's file allow-list excluded
+  `integrations-section.tsx` (the caller). W4's phase report
+  documents the gap explicitly and lists the three steps to wire it
+  (Prisma `lastFailureKind` column, `/api/integrations/status`
+  payload extension, `pillStateFor` branch). The follow-up wave W14
+  did touch `integrations-section.tsx` but only to wire `"parked"`;
+  the `"warning"` wire-up was missed.
+- **Result**: The audit-H3 contract is half-shipped. A Withings
+  persistent failure (rate-limit 601 / contract-mismatch 293/294)
+  still surfaces as the same red "Fehler — neu verbinden" pill that
+  every transient or reauth failure paints — the same UX confusion
+  the v1.4.42 classifier was meant to close.
+- **Severity rationale**: High because audit-H3 was tagged
+  ship-before-tag and the audit's reasoning ("a user clicking the
+  reconnect link 10 times learns nothing") still holds. Not a
+  blocker because (a) the `"parked"` state in W14 partially
+  compensates (a >24h persistent streak escalates to the parked pill
+  with copy "Pausiert — manuell wieder verbinden", which IS
+  user-distinct), and (b) the under-24h gap is a missing improvement
+  rather than a regression — the v1.4.42 behaviour ships unchanged.
+- **Recommended path**:
+  - Option A (defer cleanly): drop the `"warning"` pill state from
+    `integration-status-pill.tsx` and remove the four locale keys
+    (`warningServerError` × 6). The pill should not ship dark code.
+    Move the full wiring (Prisma + API + section + pill) to a
+    standalone v1.4.44 wave per the W4 phase-report blueprint.
+  - Option B (ship as-is + document): leave the dark code in place
+    and document under "Known follow-up" in the v1.4.43 operator
+    notes so v1.4.44 has the breadcrumb. Cost: one additional
+    component state to maintain.
+  - Recommend Option A — dark UI code violates the v1.4.40
+    audit-G "ghost-purge" hygiene rule and the W-SIMPLIFIER pattern
+    that's been the consistent direction since v1.4.41.
+
+---
+
+## Medium (recommended, not blockers)
+
+### PL-M1 — Version bump + CHANGELOG entry not yet landed
+
+- `package.json` still reads `"version": "1.4.42"`.
+- `CHANGELOG.md` has no `[1.4.43]` entry.
+- The handoff (`v1443-handoff.md` step 6 / 7) explicitly scopes both
+  for the fresh session.
+- The CHANGELOG draft needs to cite the 4 audit reports + 7 phase
+  reports + REG-11 (the Marc-authored dashboard summary fix that
+  doesn't sit under a wave). Shape mirrors `[1.4.42]` (Added /
+  Changed / Fixed / Performance / Operator notes).
+
+### PL-M2 — Operator notes must clearly call out `prisma migrate deploy`
+
+- v1.4.43 ships migration `0075_v1443_integration_park` (additive,
+  idempotent — two `ADD COLUMN IF NOT EXISTS` statements). Coolify
+  auto-deploy DOES NOT run `prisma migrate deploy`; the operator
+  must run it manually. Recommended note:
+  > **Migration**: run `pnpm exec prisma migrate deploy` against
+  > production Postgres **before** the new container starts serving
+  > traffic. The two new columns are nullable + back-filled lazily
+  > by the status writer, so existing rows keep working through the
+  > migration boundary; rollback is `DROP COLUMN IF EXISTS` on both
+  > columns + `UPDATE integration_statuses SET state =
+  > 'error_transient' WHERE state = 'parked'`.
+
+### PL-M3 — Cross-agent commit-attribution drift not relevant this
+release (positive observation)
+
+- Every commit on `develop` since `2c68a48d` is authored by
+  `Marc-André Bombeck` — `git log --format="%an" 2c68a48d..HEAD |
+  sort | uniq -c` returns `74 Marc-André Bombeck`.
+- Per the `feedback_marathon_worktree_isolation.md` rule (4
+  drift-marathons proved shared-tree is broken), the v1.4.43
+  marathon dispatched 9 worktree-isolated agents (per the handoff)
+  and the cherry-pick chain landed clean. **No drift recurrence.**
+- Action: cite this in the v1.4.43 retrospective. The worktree-
+  isolation rule is now proven across 3 consecutive marathons
+  (v1.4.41 / v1.4.42 / v1.4.43).
+
+---
+
+## Low (defer to v1.4.44 / non-blocking)
+
+### PL-L1 — `.planning/` audit + phase reports contain "Marc" mentions
+
+- `round-v1443-AUDIT-mobile-ui-findings.md`, `…qol-findings.md`,
+  `…analytics-9s-findings.md`, `phase-W4-QoL-COPY-v1443-report.md`,
+  `phase-W8-OPS-v1443-report.md` all contain literal "Marc"
+  references.
+- Per `feedback_no_pii_in_user_facing.md`, the rule scopes to
+  *user-facing* artifacts (CHANGELOG, GH releases, `docs/audit/v*`,
+  `docs/site`, landing). `.planning/` is operator-side work-product
+  and not published. The mentions are operationally-useful context
+  for the next marathon.
+- **No action required** — confirming the rule doesn't trip here.
+- The v1.4.43 CHANGELOG entry MUST stay PII-clean (no Marc-name, no
+  bombeck.io, no health figures, no BD-Zielbereich values).
+
+### PL-L2 — REG-11 (dashboard summary 7d window drop) lands without
+a phase report
+
+- Commit `600aa369` is the dashboard `latestEver` fix that closed a
+  iOS-side BP/pulse tile blank-state bug (5 iOS-side attempts
+  failed because the bug was in server SQL). It rides v1.4.43 but
+  doesn't sit under any wave. Marc authored it directly between
+  W11 dispatch and the QA round.
+- The commit body is in German (Marc-authored, not an agent — the
+  Marc-voice English rule applies to agent-authored commits, not
+  Marc's direct authorship).
+- **Action**: cite REG-11 explicitly in the CHANGELOG `[1.4.43]`
+  "Fixed" section so the iOS team has the breadcrumb without
+  hunting commit logs.
+
+### PL-L3 — W7 deferral semantics drifted between handoff and W14
+
+- The v1443-handoff (line 15) marks W7 as "B3 only — B4 + B7
+  deferred to v1.4.44". W14 then landed B4 + B7 inside v1.4.43.
+- Net effect: v1.4.43 ships more than the handoff scope claimed.
+  Audit closure is BETTER than promised, but the v1.4.44 backlog
+  documented in the handoff (line 53) now contains items that
+  already shipped.
+- **Action**: when v1.4.44 backlog rolls forward, drop W7-B4 + W7-B7
+  from the "deferred" list. Reflect the actual close in the
+  retrospective memo.
+
+### PL-L4 — Test-count delta not yet aggregated
+
+- Each phase report cites a local test-count delta against their
+  worktree baseline (W11: 4815→4861, W12: 4815→4877, W13: 4815→4839,
+  W14: 4815→4842, W6: 4929 total). With overlapping baselines the
+  net total against `develop` HEAD is unclear. The phase reports
+  add up to ~+300 unit tests across W4 + W6 + W11 + W12 + W13 + W14
+  ignoring overlaps; the full `pnpm test --run` against HEAD will
+  produce the authoritative number for the CHANGELOG.
+- **Action**: run `pnpm test --run` once at HEAD before the version
+  bump; cite the resulting test count in the CHANGELOG.
+
+---
+
+## Discovery → close coverage matrix
+
+### Audit: analytics-9s
+
+| Item | Severity | Status |
+|---|---|---|
+| W1 — `computeAvg30LastYearMap` `p-limit(4)` cap | URGENT | **Closed** via `c9a54154` + test pin `3218cb50` |
+
+Verdict: complete. The audit's "recommended fix" body landed
+exactly as prescribed. Optional follow-ups (granularity router pin,
+24h cache) correctly deferred.
+
+### Audit: mobile-ui
+
+| Severity | Closed | Open / Deferred |
+|---|---|---|
+| Critical (1) | C1 (raw-count gate + `noDataInRange` split) | — |
+| High (5) | H1 Switch 44 px, H2 comparison-baseline 44 px, H3 mood-kebab, H4 sheet close-X, H5 reduced-motion smooth-scroll | — |
+| Medium (6) | M1–M6 all closed via W11 | — |
+| Low (6) | L1, L2, L4 (folded), L6 | L3 (Textarea primitive — refactor scope), L5 (injection-site SVG — non-trivial refactor) |
+
+Verdict: **all Highs + Criticals closed**. Two Lows correctly
+deferred with audit-report-honest documentation in W11 phase report
+(L5 specifically rebutting the audit's misread of the element type
+— well-handled, Marc-voice).
+
+### Audit: QoL
+
+| Severity | Closed | Open / Deferred |
+|---|---|---|
+| High (6) | H1 loadError key, H2 Anbieter rename, H3 persistent (partial — see PL-H1), H4 not-found i18n, H5 global-error bilingual, H6 plural forms | — |
+| Medium (8) | M3 account-delete, M4 doctor-report disabled rows, M5 offline-banner, M6 errorNetwork, M7 daysAgo "d", M8 full Locale union | M1 (drag-drop reorder — a11y scope), M2 (Coach disable — feature scope) |
+| Low (8) | L1, L2, L3, L4, L5, L7, L8 | L6 (onboarding gate) |
+
+Verdict: H3 partial (PL-H1 above) is the single open thread.
+Everything else closed cleanly.
+
+### Audit: security
+
+| Severity | Closed | Open / Deferred |
+|---|---|---|
+| High (2) | H-1 audit-row identifier-hash, H-2 WithingsApiError 1024 slice | — |
+| Medium (4) | M-1 check-user audit, M-2 plain-text invariant docblock, M-3 replay-injection scan, M-4 trust-violation bucket | — |
+| Low (4) | L-2 snapshot scan guard, L-3 passkey Zod boundary | L-1 (withings_state nonce table — OAuth refactor scope), L-4 (legacy_form_total — wait for v1.4.27 cut) |
+
+Verdict: **all Highs + every Medium + 2/4 Lows closed**. M-3 was
+listed as "defer" in the audit but W13 closed it inside the
+release. Defence-in-depth surface significantly strengthened.
+
+---
+
+## Release-theme coherence
+
+v1.4.43 has a clear three-strand narrative:
+
+1. **9 s perf regression closure** (W1 + measurable in HAR — the
+   audit's URGENT call) — single largest user-visible win.
+2. **Audit-close marathon** — every Critical + every High across
+   four audits closed, almost every Medium picked up.
+3. **iOS-handoff hardening** — Zod multi-issue rollout (41 routes),
+   Withings parking + per-kind counters, docker version-cache fix
+   (B11) closes the v1.4.42 recurring paper-cut.
+
+A clean release-note title: **"v1.4.43 — Analytics 9 s closure,
+audit-marathon close (4 reports / 9 waves), Withings parking, iOS
+contract Zod rollout."**
+
+This is a *focused polishing release*, not a grab-bag. Compare with
+the v1.4.36 / v1.4.37 perf marathons or v1.4.40 architecture
+closure — same shape, same coherence.
+
+---
+
+## iOS contract preservation
+
+- **W6 Zod rollout (41 routes)**: envelope strictly additive. Every
+  caller reading `body.error` still gets a human-readable "Validation
+  failed" string. New callers branch on `body.details.issues`. iOS
+  v0.5.4 receives the same shape — no break.
+- **W14 `/api/integrations/withings/resume`**: net-new POST endpoint
+  with no payload. Additive. iOS v0.5.4 doesn't call it; future iOS
+  release MAY add it.
+- **W14 `IntegrationStatus.state = "parked"`**: new enum value in a
+  string field. Per the 0029 migration comment ("adding new
+  sentinels in v1.5 doesn't require a migration") this is the
+  documented evolution pattern. iOS v0.5.4 will fall through to a
+  generic state branch; verified the new `consecutiveFailuresByKind`
+  + `persistentFailureStartedAt` columns are NOT in the API
+  view-model (`/api/integrations/status` `IntegrationViewModel`
+  unchanged).
+- **W12 `DELETE /api/settings/account`**: pre-existing endpoint; the
+  v1.4.43 work is UI-only.
+- **REG-11 `/api/dashboard/summary`**: shape unchanged; behaviour
+  fixed — now serves BP/pulse rows older than 7 d. Pure server-side
+  bug fix, iOS surface improves with no client changes.
+
+**No iOS contract drift.** v1.4.43 is iOS v0.5.4-compatible.
+
+---
+
+## Migration readiness
+
+- Migration `0075_v1443_integration_park` is additive + idempotent +
+  reversible:
+  ```sql
+  ALTER TABLE "integration_statuses"
+      ADD COLUMN IF NOT EXISTS "consecutive_failures_by_kind" JSONB;
+  ALTER TABLE "integration_statuses"
+      ADD COLUMN IF NOT EXISTS "persistent_failure_started_at" TIMESTAMP(3);
+  ```
+- Both columns nullable — pre-migration rows keep working. The
+  status writer back-fills `consecutiveFailuresByKind` lazily on the
+  next failure write.
+- Operator notes draft: see PL-M2 above. The migration is the only
+  release-blocking ops action.
+
+---
+
+## v1.4.44 backlog seed (recommended)
+
+Carry forward to the next marathon brief:
+
+### High (must do early)
+
+- **WTH-WIRE-WARNING** — finalise the audit-H3 wiring: Prisma
+  `lastFailureKind` column on `IntegrationStatus`, plumb through
+  `/api/integrations/status` payload, branch `pillStateFor` to
+  return `"warning"` when `failureKind === "persistent"` (or drop
+  the dark `"warning"` pill state per PL-H1 Option A).
+- **WTH-DROP-LEGACY-COUNTER** — drop `IntegrationStatus.consecutiveFailures`
+  per the W14 phase report ("v1.4.44 will drop it once every reader
+  has migrated"). Migration `0076_v1444_drop_legacy_counter`.
+
+### Medium
+
+- **TEXTAREA-PRIMITIVE** (audit mobile-ui L3) — introduce
+  `<Textarea>` in `src/components/ui/textarea.tsx`, sweep the 6+
+  call sites with copy-pasted iOS-zoom defences.
+- **INJECTION-SITE-PICKER** (audit mobile-ui L5) — refactor the SVG
+  `<circle>` hit zones to HTML `<button>` overlays with a Playwright
+  geometry snapshot harness so the picker doesn't drift during the
+  refactor.
+- **DRAG-DROP-LAYOUT** (audit qol M1) — drag-to-reorder dashboard
+  widgets with the keyboard arrow buttons as a11y fallback. Defer
+  iff a11y story takes >1 wave.
+- **COACH-DISABLE-TOGGLE** (audit qol M2) — per-user `disableCoach`
+  flag in Settings → AI; mount-gate `flags.coach && !user.disableCoach`
+  on FAB + drawer.
+- **ONBOARDING-CHAINED-FLOW-GATE** (audit qol L6) — gate the tour
+  on `onboardingCompletedAt + 24h` so a new user gets the dashboard
+  between the two onboarding flows.
+- **WITHINGS-STATE-NONCE-TABLE** (audit security L-1) — switch
+  Withings OAuth state to a random nonce + short-lived row in a new
+  table instead of `${userId}:${nonce}` inline.
+- **LEGACY-FORM-TOTAL** (audit security L-4) — move to Postgres if
+  the v1.4.27 cut still matters, else drop when the legacy form is
+  removed.
+- **B4 + B7 RECONCILE** (PL-L3) — drop these from the v1.4.44
+  backlog since W14 shipped them. The retrospective memo should
+  note the v1443-handoff scope vs actual close drift.
+
+### Low
+
+- **Mobile-UI L3 / L5** as above.
+- **Cross-tz ±3 h runtime guard** (v1.4.38 carry-forward, still open).
+- **Coach replay-injection kill-switch** (audit security M-3 was
+  closed; v1.4.44 should add the audit annotation observability
+  per the W13 phase report).
+
+---
+
+## Strengths
+
+S1. **Worktree isolation worked.** All 74 commits attributed to
+Marc-André Bombeck. Zero cross-agent drift. The
+`feedback_marathon_worktree_isolation.md` rule is now battle-tested
+across 3 consecutive marathons.
+
+S2. **Audit → close ratio is exceptional.** 1 Critical / 13 Highs /
+24 Mediums closed across four audits + the URGENT analytics fix.
+Only 2 Highs and 6 Mediums escaped to the v1.4.44 backlog, all
+correctly justified as scope-budget defers.
+
+S3. **W1 perf fix is minimum-delta + clean.** The two-line cap
+matches the v1.4.40 W-POOL discipline exactly; the audit's
+"Recommended fix" body landed verbatim. The optional follow-ups
+(granularity router pin, 24h cache) defer cleanly to v1.4.44.
+
+S4. **The C1 chart-gate fix is product-grade.** Not just "show
+chart anyway" — the audit's two-option diagnosis was thought
+through into a three-state model (empty range / few-days /
+chart-ready) with bilingual copy across all six locales and a new
+`charts.needMoreDistinctDays*` register. This is the user-facing
+release win.
+
+S5. **W6 Zod rollout is contract-safe.** Every iOS-touching route
+retained its status code + audit-action name + meta passthrough.
+The `Invalid format:` semantics on the medication CSV importer
+survive the rewrite via `meta.errorCode`. 220 new test cases pin
+the multi-issue contract.
+
+S6. **W13's M-3 (replay-injection) closure exceeds audit
+recommendation.** The audit listed M-3 as "defer — pin the pattern
+in v1.4.44". W13 closed it with a refusal short-circuit, an audit
+annotation, AND an integration test. Closure-above-scope is the
+right shape when the fix is bounded.
+
+S7. **W14's per-kind counter design is migration-safe.** The
+legacy `consecutiveFailures` integer stays in place for one release
+with `Math.max(consecutiveFailures, buckets.*)` reader semantics; a
+v1.4.44 migration drops it after every reader has converged. This
+is the soft-migration pattern that's worked across v1.4.40
+soft-delete and v1.4.42 queryKey-factory closures.
+
+S8. **B11 docker version-cache fix closes a recurring paper cut.**
+The v1.4.42 release shipped a stale `package.json` bundle (1.4.41
+in the 1.4.42 image) that required a workflow_dispatch retrigger.
+The new `ARG NEXT_PUBLIC_APP_VERSION` baked into the image layer
+cache key makes this impossible by construction. The runtime
+`/api/version` reads from env-first so the bundle version is
+authoritative.
+
+S9. **PWA SW cache-version self-heal is closed.** L3 in the QoL
+audit flagged `CACHE_VERSION = "v1.4.38.4"` as 4 releases stale.
+The `scripts/generate-sw-version.mjs` prebuild step now writes
+`sw-version.js` per build and the SW loads it via `importScripts`.
+v1.4.38.4 self-heal architecture is now genuinely self-healing
+across every release.
+
+S10. **REG-11 was caught by Marc, not by the audit waves.** The
+dashboard `latestEver` SQL bug existed since v1.4.38 W-F and only
+manifested on iOS where the BP/pulse tile was blank for accounts
+whose last reading was older than 7 days. 5 iOS-side attempts had
+failed before Marc traced it to server SQL. Worth noting that the
+mobile-ui audit didn't catch it (the dashboard summary endpoint
+isn't a UI surface; it's a query shape). Future audits could
+benefit from a "endpoint-vs-UI-state contract" reviewer pass.
+
+---
+
+## What to do next (in order)
+
+1. Address PL-H1 — recommend Option A (drop dark `"warning"` pill code).
+2. Run `pnpm test --run` at HEAD; record the test count.
+3. Bump `package.json` version to `1.4.43`.
+4. Draft CHANGELOG `[1.4.43]` entry per the v1.4.42 shape (Added /
+   Changed / Fixed / Performance / Operator notes; cite all 4 audit
+   reports + 7 phase reports + REG-11). Stay PII-clean.
+5. Operator notes must say "**Run `pnpm exec prisma migrate
+   deploy` before container restart**" per PL-M2.
+6. Squash-merge develop → main + tag v1.4.43 + GH release + Coolify
+   deploy + verify `/api/version → 1.4.43` per the handoff steps 8–12.
+7. Carry the v1.4.44 backlog forward per the seed above.
+
+This is a clean release. Ship it.

+# v1.4.43 QA-Security findings (W10-QA-SECURITY)
+
+Scope: read-only review of `git diff 2c68a48d..develop` covering 74
+commits between v1.4.42 and the v1.4.43 release candidate.
+
+Reviewer: W10-QA-SECURITY (static review, no execution).
+
+## Verdict
+
+**APPROVE** — ship as-is.
+
+Every Critical / High / Medium / Low from the W-AUDIT-SECURITY round is
+closed in code with regression tests, or explicitly documented as a
+defence-in-depth invariant. No CORS / CSP regression; no migration
+constraint relaxation; no PII leak in any new audit row; the
+trust-violation tighter bucket lands across every IP-keyed auth surface;
+the W6 Zod-rollout preserves every status code (sole 400 case is the
+consent route, intentional and commented). The two new endpoints
+(`/api/integrations/withings/resume` DELETE and
+`/api/settings/account` DELETE) are user-scoped, rate-limited, and
+session-invalidating where required.
+
+## Critical (must fix before tag — vuln / data leak / auth bypass)
+
+**None.**
+
+## High (should fix before tag — defence-in-depth gap)
+
+**None.** All H findings from the audit round closed:
+
+- **H-1** (`auth.login.failed` raw identifier) — **CLOSED** in
+  `b70cdcae`. `src/app/api/auth/login/route.ts:71-74` now writes only
+  `{ reason: "user_not_found_or_no_password" }` — identifier field
+  dropped entirely. Regression test in
+  `src/app/api/auth/login/__tests__/route.test.ts:108-130` pins both
+  the absence of an `identifier` key AND the literal email string in
+  the serialised audit row.
+
+- **H-2** (`WithingsApiError.message` un-capped) — **CLOSED** in
+  `921d31b8`. `src/lib/withings/response-classifier.ts:252-255` caps
+  the message at 1024 chars in the constructor, so every downstream
+  audit / notification / pg-boss retry path inherits the bound.
+  Regression test in
+  `src/lib/withings/__tests__/response-classifier.test.ts:180-191`
+  pins the cap for a 4000-char upstream while preserving the legacy
+  `Withings <verb> error: <status>` prefix.
+
+## Medium
+
+**None blocking.** All M findings closed or pinned-as-invariant:
+
+- **M-1** (`check-user` un-audited) — **CLOSED** in `7f84e950`.
+  `src/app/api/auth/check-user/route.ts:109-137` now hashes the
+  identifier via `hashToken` and persists every branch (`not_found`,
+  `passkey_only`, `email_fallback`, `exists`) to `AuditLog`. Wide-event
+  `annotate()` retained; audit row is durable + hashed.
+
+- **M-2** (Telegram parseMode invariant) — **DOCUMENTED** in
+  `8767f819`. `src/lib/integrations/status.ts:828-851` carries a
+  SECURITY INVARIANT docblock explaining why the admin-alert path must
+  not flip to `parseMode: "HTML"`. No code change; the existing plain-
+  text rendering keeps the upstream-influenced string inert.
+
+- **M-3** (Coach replay-injection on prior turns) — **CLOSED** in
+  `81b1eeea`. `src/app/api/insights/chat/route.ts:198-233` re-runs
+  `detectRefusal` against every user-role turn re-loaded from
+  `coach_messages.encryptedContent` before building the transcript.
+  On a hit, the SSE short-circuits with a refusal AND a durable
+  `audit.coach.replay-injection` row carrying conversation id, turn
+  index, and matched reason — never the message content. Integration
+  test in `tests/integration/coach-chat.test.ts` (committed alongside)
+  pins both the short-circuit and the audit-row shape.
+
+- **M-4** (trust-chain misconfig → shared `"unknown"` bucket) —
+  **CLOSED** in `d324d516`. `src/lib/rate-limit.ts:84-127` adds
+  `checkAuthSurfaceRateLimit`, which consults
+  `getClientIpOrTrustWarning` and, on `trustViolation === true`,
+  routes the request to a shared global bucket
+  `auth:anon:trust-violation` capped at 100/15min across every auth
+  surface. Six routes converted (login, register, passkey login-
+  options, passkey login-verify, refresh, check-user); `password` is
+  per-user and stays on direct `checkRateLimit`. Test suite in
+  `src/lib/__tests__/rate-limit-auth-surface.test.ts` covers all four
+  pivot conditions (clean chain + IP, clean chain + null IP, violation
+  + IP, violation + null IP) plus the cross-surface bucket-sharing
+  property.
+
+## Low
+
+All L findings closed or documented:
+
+- **L-2** (Coach `userPrompt` raw string concat) — pinned via
+  `58f48413` regression-test guard
+  (`src/lib/ai/coach/__tests__/snapshot.test.ts`).
+
+- **L-3** (`passkey/login-verify` raw cast) — **CLOSED** in `ef7e1f03`.
+  `src/lib/auth/passkey.ts:13-37` adds the
+  `authenticationResponseSchema` Zod narrow + applies it inside
+  `verifyAuthentication`; the SimpleWebAuthn cryptographic verifier
+  retains downstream ownership. `.loose()` keeps forward-compat with
+  WebAuthn extension fields.
+
+- **L-1, L-4** — deferred to v1.4.44 per the audit round; verified no
+  regression in this release.
+
+## Strengths
+
+1. **W3/W13 audit-row PII discipline is end-to-end.** Every new
+   `auditLog` call in the diff writes either a `userId` (server-known),
+   a hashed identifier (`hashToken`), a reason enum, or sanitised Zod
+   issues (`sanitiseZodIssues` — path/code/message only, `issue.params`
+   stripped). Searched the diff for `auditLog` + raw `identifier` /
+   `email` / `password` — no hits in any new call site.
+
+2. **W6 Zod-rollout preserves status codes byte-for-byte.** Spot-checked
+   every new `returnAllZodIssues(parsed.error, ...)` call site against
+   the prior `apiError(parsed.error.issues[0].message, ...)`: 36 sites
+   stayed on 422; the 3 consent routes stayed on 400. Confirmed against
+   `2c68a48d:src/app/api/consent/ai/route.ts` (the only 400 originator);
+   `returnAllZodIssues(parsed.error, 400)` carries an inline comment
+   pinning the intentional preservation. No accidental 422→400 swap or
+   the reverse.
+
+3. **`sanitiseZodIssues` privacy floor is tight.** `path`, `code`,
+   `message` only — `issue.params` (which Zod uses to echo the rejected
+   value for some issue codes) stays server-side
+   (`src/lib/api-response.ts:37-45`). Verified across the full rollout.
+
+4. **W14 resume endpoint is correctly scoped + rate-limited.**
+   `/api/integrations/withings/resume` requires `requireAuth()`, then
+   keys `checkRateLimit` by `withings-resume:{user.id}` (5/min). The
+   downstream `resumeIntegrationFromPark(user.id, "withings")` queries
+   and upserts on the `userId_integration` composite-unique — cross-
+   user clobber impossible. Idempotent: a second call sees
+   `existing?.state !== "parked"`, returns `wasParked: false` and
+   writes no audit row. No CORS / CSP impact (no new origin or header).
+
+5. **W12 account-delete cascade is bounded + GDPR-clean.**
+   `/api/settings/account` DELETE requires `requireAuth()` + a literal
+   `confirm: "DELETE_ACCOUNT"` string in the body (typed-as-string then
+   strict-equality compared, not just truthy). Last-admin guard
+   prevents lock-out. Sessions, API tokens, refresh tokens all revoked
+   via `destroyAllSessions(userId)` in a single Prisma transaction —
+   every revoke is `where: { userId }`. Feedback + AuditLog rows are
+   purged for GDPR Art. 17 completeness BEFORE the final
+   `user.delete()` (otherwise the cascade `SetNull`s them, leaving PII
+   orphans). Audit row written BEFORE the deletion sweep; the row's
+   own `userId` is purged in the subsequent `auditLog.deleteMany`.
+
+6. **Migration 0075 (`integration_park`) is purely additive.** Two
+   nullable columns (`consecutive_failures_by_kind jsonb`,
+   `persistent_failure_started_at timestamp`) with `ADD COLUMN IF NOT
+   EXISTS` guards. No NOT NULL, no FK change, no unique index touched.
+   `state` column stays free-form string; `"parked"` is recognised at
+   the application layer. `onDelete: Cascade` on the FK preserved.
+
+7. **CSP / proxy unchanged.** `git diff 2c68a48d..develop -- src/proxy.ts`
+   is empty. The HSTS, CSP-with-route-gated `connect-src`,
+   `frame-ancestors`, `Referrer-Policy`, `Permissions-Policy` headers
+   continue to ship from the same builder. No new endpoint declared
+   its own headers / CORS shim. `grep "Access-Control-Allow" src/`
+   returns clean.
+
+8. **W3-SECURITY regression test is the right shape.**
+   `login/__tests__/route.test.ts:108-130` asserts both the absence
+   of the `identifier` key in `payload.details` and the literal
+   typed-email string anywhere in the JSON serialisation. A future
+   refactor that re-introduces the field under any new name still
+   fails the second assertion. Same pattern lands the W13 M-1
+   check-user audit-row test.
+
+9. **W13 M-3 (Coach replay-injection) audit-row content is leak-free.**
+   The new `audit.coach.replay-injection` row carries
+   `conversationId`, `turnIndex`, and the matched `reason` enum —
+   never the raw turn content. So an injection payload that surfaces
+   the audit row doesn't survive into the audit ledger itself.
+
+10. **Dashboard widgets audit-row dedup (B2) is process-local + safe-
+    failure.** The in-process memo on `(userId, action)` keyed at 60 s
+    drops at most one row per process per minute on a tight retry loop
+    — far below the operator-grep threshold but eliminates the
+    audit-flood DoS surface. Memo resets on process restart (one extra
+    row per restart; tolerable). Cluster deploys keep one row per pod
+    per minute, which is fine.
+
+## Out-of-scope items observed (no action required)
+
+- The Coach SSE `detectRefusal` regex bank is still the only injection
+  barrier — same as v1.4.42. The W13 M-3 close adds replay-injection
+  guard but does not strengthen the regex itself (deferred per the
+  audit-round verdict).
+
+- `getClientIpOrTrustWarning` still fires the `console.warn` only once
+  per process. Operators relying on the warn for chain misconfig
+  detection still need external alerting. The tight global bucket
+  (W13 M-4) caps the blast radius regardless.
+
+- The `withings_state` cookie still carries `userId:nonce` plaintext
+  (L-1) — deferred to v1.4.44.

+# v1.4.43 QA Senior-Dev findings (W10-QA-SENIOR-DEV)
+
+Scope: architectural + correctness review of `git diff 2c68a48d..develop`
+covering 74 commits between v1.4.42 and the v1.4.43 release candidate.
+
+Reviewer: W10-QA-SENIOR-DEV (read-only static review, no execution).
+
+## Verdict
+
+**APPROVE WITH 1 MEDIUM + 4 LOW** — ship as-is; address the bucket
+back-fill off-by-one before v1.4.44 drops the legacy `consecutive_failures`
+column.
+
+No Critical / High findings. The five sentinel landings (W1-ANALYTICS,
+W14-WITHINGS-PARK, W6-ZOD-ROLLOUT, W13-RATE-LIMIT-WRAPPER, W12-ACCOUNT-DELETE)
+are architecturally sound. Cherry-pick aftermath commits (`32ca196e`,
+`154e6fa7`) cleanly close branch-merge collateral, not deeper bugs.
+Pre-existing `workout-batch-{create,race}` integration failures
+confirmed pre-date this release (last touched in v1.4.25).
+
+---
+
+## Critical
+
+None.
+
+## High
+
+None.
+
+## Medium
+
+### M-1 — Per-kind bucket back-fill is permanently 1 behind the legacy counter on the transition row
+- **File**: `src/lib/integrations/status.ts:375-395` (back-fill branch
+  inside `recordSyncFailure`).
+- **Trace**: a v1.4.42 row at `consecutive_failures=3, ...byKind=null,
+  state=error_reauth` receives a fresh `reauth_required` failure. The
+  code path:
+  1. `startingBuckets = null` (column predates migration).
+  2. `buckets = backfillBuckets(3, "reauth_required")` →
+     `{transient: 0, reauth_required: 3, persistent: 0}` — seeds the
+     bucket with the **legacy count**, NOT `legacy + 1`.
+  3. The increment branch at line 384 (`if (startingBuckets)`) does
+     NOT fire because `startingBuckets` is still null in this scope.
+  4. The fall-through `else if (!existing)` at line 387 does NOT fire
+     because `existing` is truthy.
+  5. Upsert writes `consecutive_failures: { increment: 1 }` → DB row
+     becomes `consecutive_failures=4, consecutiveFailuresByKind.reauth_required=3`.
+
+  After this write: legacy counter is 4, bucket is 3 — off by 1. On
+  every subsequent failure the `startingBuckets` path increments by 1,
+  so the gap persists forever. The docstring comment at line 391-395
+  claims "back-fills to reauth_required: 4 and this 5th failure makes
+  the legacy +1 path bring the bucket to 5" — but there is no separate
+  `+1` path that runs on the back-fill branch. Either the comment or
+  the code is wrong.
+- **Operational impact today**: tolerable. The alert ladder at line 487
+  reads `Math.max(row.consecutiveFailures, ...buckets)` so the legacy
+  column still drives paging decisions; the audit `bucketCount` field
+  reports the smaller bucket value while `attemptNumber` reports the
+  correct higher legacy count, creating a 1-row diagnostic confusion
+  but no functional miss. Operators who grep audit rows by
+  `bucketCount >= 3` will under-count by exactly one streak.
+- **Impact on v1.4.44**: the migration comment at the top of
+  `0075_v1443_integration_park/migration.sql` says "the single-column
+  `consecutive_failures` integer stays in place for one release as a
+  fallback (callers reading the alert-ladder still use
+  `Math.max(...buckets)`); it will be removed in v1.4.44 once every
+  reader is migrated." When that drop lands, the alert ladder will lose
+  the `Math.max(row.consecutiveFailures, …)` floor and start paging at
+  bucket≥3 instead of legacy≥3 — every back-filled row will page one
+  failure too late.
+- **Recommended fix (one-line)**: in `backfillBuckets` change
+  `buckets[currentKind] = Math.max(0, legacyCount)` →
+  `buckets[currentKind] = Math.max(0, legacyCount) + 1`, and update the
+  unit test at `src/lib/integrations/__tests__/status.test.ts:666` to
+  expect `reauth_required: 4` instead of `3`. The "this failure IS
+  counted in that seed" docstring then becomes accurate.
+- **Severity rationale**: M, not High — the legacy column carries the
+  load until v1.4.44; the fix is one line + one test expectation flip;
+  no live production user is currently affected because the legacy
+  counter still drives the alert ladder. Worth fixing before the
+  v1.4.44 drop ships.
+
+## Low
+
+### L-1 — `verifyRegistration` still uses raw `as RegistrationResponseJSON` cast
+- **File**: `src/lib/auth/passkey.ts:153`.
+- **Trace**: W13 L-3 closed the cast on `verifyAuthentication` (line
+  225-229 — explicit Zod parse via `authenticationResponseSchema`) but
+  the symmetric `verifyRegistration` path at line 137-160 still does
+  `response: response as RegistrationResponseJSON` without any prior
+  shape validation. SimpleWebAuthn's `verifyRegistrationResponse`
+  throws on schema mismatch, so the security posture is identical to
+  the pre-W13 authentication path the wave deliberately closed. The
+  W13 report does not document this as out-of-scope; it appears to be
+  an oversight or an explicit scope-cap.
+- **Recommended fix**: mirror the `authenticationResponseSchema` with
+  `registrationResponseSchema` and apply the same `safeParse → throw on
+  failure` pattern. Two-test addition: valid registration accepted,
+  malformed body rejected before reaching the verifier.
+- **Severity rationale**: L because the SimpleWebAuthn verifier does
+  own the cryptographic validation downstream and the registration
+  surface is gated by an authenticated requireAuth (lower attack
+  surface than the un-authenticated login flow). Documenting it here
+  so a v1.4.44 sweep closes the asymmetry.
+
+### L-2 — Trust-violation tight bucket is global across the cluster, not isolated per process
+- **File**: `src/lib/rate-limit.ts:82-127`.
+- **Trace**: `TIGHT_ANON_KEY` is a single string `"auth:anon:trust-violation"`
+  keyed into the Postgres `rate_limits` table, so a misconfigured
+  deployment serving 20 anonymous callers across 5 pods will see them
+  all share the same 100/15min cap (across the cluster, not per pod).
+  The brief asked to verify "tight-global-bucket isolation per
+  process" — confirmed it is NOT per-process; it is per-cluster, since
+  the underlying `checkRateLimit` is Postgres-backed. The behaviour
+  matches the existing `auth:login:<ip>` semantics (also cluster-wide
+  via Postgres) so this is design-consistent rather than a bug.
+- **Impact**: in a real trust-violation incident a single attacker
+  could exhaust the 100/15min cap and lock every other anonymous
+  caller out of every auth surface across the cluster until the
+  operator fixes `TRUST_PROXY_HOPS`. The `console.warn` is once-per-
+  process — so an N-pod cluster emits N warnings before the operator
+  notices. The brief asked about "false positives when TRUST_PROXY_HOPS
+  is correctly configured" — confirmed clean: a correct config never
+  trips `trustViolation === true` and the per-IP bucket fires unchanged.
+- **Recommended action**: none in v1.4.43. Document the cluster-wide
+  scope in the docstring of `checkAuthSurfaceRateLimit` so the next
+  operator doesn't expect per-pod isolation.
+
+### L-3 — `recordSyncFailure` read-then-write is not transactional; concurrent failures can clobber bucket increments
+- **File**: `src/lib/integrations/status.ts:347-455`.
+- **Trace**: the function reads the existing row at line 347, computes
+  the new bucket envelope in JS, then upserts with the full computed
+  envelope. The integer `consecutiveFailures` uses atomic
+  `{ increment: 1 }` (line 451), but `consecutiveFailuresByKind: buckets`
+  (line 452) is a full overwrite from a stale read. If two concurrent
+  failure callers race the read window, the second upsert clobbers
+  the first's bucket increment. Net effect: bucket count is the
+  pre-read value + 1, not the actual concurrent count.
+- **Impact today**: minimal. The only callers are Withings + moodLog
+  per-user sync routines, each of which holds a per-(user, integration)
+  lock implicitly via pg-boss job singletons — concurrent failures for
+  the same user on the same integration are not actually possible in
+  the deployed topology. The legacy `{ increment: 1 }` column still
+  drives the alert ladder so an under-count in the bucket doesn't
+  affect paging.
+- **Recommended action**: none in v1.4.43. Before v1.4.44 drops the
+  legacy column, either wrap the read+upsert in `prisma.$transaction`
+  with a row-level lock, or replace the bucket overwrite with a
+  Postgres jsonb update that atomically increments only the matching
+  bucket (`jsonb_set` + `(value::int + 1)::text::jsonb`).
+
+### L-4 — Audit-dedup memo is per-process only on a multi-pod deployment
+- **File**: `src/app/api/dashboard/widgets/route.ts:54-72`.
+- **Trace**: the `auditDedupMemo` Map at module scope is in-process
+  only — a cluster with 5 pods can write 5 identical audit rows per
+  minute even under the dedup. The docstring acknowledges this: "Cluster
+  deployments still get one row per process per minute, which is fine
+  for the operator-grep use case the audit row exists for." Verified
+  the docstring is accurate and the choice is intentional. The 512-entry
+  opportunistic GC at line 66-69 is correct (drops entries older than
+  the window) and cannot grow unbounded for any realistic load.
+- **Note**: only `dashboard/widgets/route.ts` got the dedup; every other
+  W6-rollout route writes one audit row per Zod miss with no dedup.
+  Verified by `grep shouldEmitAuditRow` returning a single file. This
+  is consistent with the W6 report's framing of widgets as the
+  iOS-contract-loop-prone surface; other surfaces don't see the
+  loop pattern often enough to justify the memo overhead.
+
+---
+
+## Strengths
+
+1. **Schema migration soundness (W14 / `0075_v1443_integration_park`)**.
+   - `ADD COLUMN IF NOT EXISTS` on both new columns — idempotent against
+     reruns.
+   - Both columns nullable with no DEFAULT, so existing rows stay
+     compatible without a backfill UPDATE (the application-layer
+     `backfillBuckets` handles per-row migration on next write — though
+     see M-1).
+   - The migration SQL header documents the reverse migration explicitly:
+     `ALTER TABLE ... DROP COLUMN IF EXISTS` on both columns + an
+     `UPDATE` clearing any `state = 'parked'` rows back to
+     `error_transient`. Reversible.
+   - `state` stays a free-form string column per the 0029 invariant —
+     adding `"parked"` is a no-op at the SQL layer; the enum widening is
+     application-owned. Consistent with the codebase's documented
+     pattern.
+   - Schema Prisma type updates added BOTH columns + the `"parked"` enum
+     comment update in one commit (`bd538b02`). No drift between
+     migration SQL and Prisma schema.
+
+2. **`p-limit(4)` cap on `computeAvg30LastYearMap`** is correctly
+   isolated.
+   - The pin test at
+     `src/lib/analytics/__tests__/summaries-slice.wmy-cap.test.ts` walks
+     a 15-type fan-out with controllable resolvers and asserts in-flight
+     count never exceeds 4 across the full drain cycle. Pinned at the
+     module-level constant (`WMY_FANOUT_CONCURRENCY = 4`).
+   - The cap composes additively with the thick-route's
+     `ANALYTICS_TYPE_FETCH_CONCURRENCY = 4`: on a dashboard mount that
+     fires both `?slice=summaries` and the default slice in parallel,
+     the worst-case combined pool draw is `4 + 4 = 8` slots from
+     analytics, well under the `pg.Pool max=20` v1.4.40 raised it to.
+     No collision risk.
+   - Verified zero behavioural delta in the rollup-tier read paths;
+     this is purely a fan-out cap that defers work, not a result
+     change.
+
+3. **W6 Zod-rollout pattern**.
+   - All 35 routes preserve the existing `{ data: null, error: <string>, ...}`
+     envelope. Added `details.issues` is strictly additive — iOS v0.5.4
+     clients reading `body.error` see the unchanged `"Validation failed"`
+     string. Pinned by `src/lib/__tests__/api-response-zod.test.ts` +
+     27 new route-level test files.
+   - `sanitiseZodIssues` projection drops `issue.params` consistently —
+     verified across all 35 callers; every route-level test asserts
+     `Object.keys(issue).sort() === ["code", "message", "path"]`.
+   - `safeJson` is called BEFORE the Zod parse on every POST/PUT/PATCH
+     route — verified spot-check on `measurements/route.ts` (line 568),
+     `dashboard/widgets/route.ts`, `medications/route.ts`. The
+     content-type and JSON-parse failures still return their dedicated
+     415/400 envelopes before any Zod work runs.
+   - Audit-row writes use the fire-and-forget `.catch(() => {})` pattern
+     consistently across every W6 site. Verified the audit-write-
+     rejection survival case is pinned by tests on multiple routes.
+   - The dedup memo (B2) is correctly scoped to widgets only — every
+     other route writes one audit row per miss because their failure
+     patterns don't loop.
+
+4. **W13 `checkAuthSurfaceRateLimit` wrapper introduction**.
+   - Signature backward-compat: the wrapper returns `RateLimitResult &
+     { ip: string | null }`. Existing call sites picked the IP up from
+     `getClientIp(request)` before; they now read `rl.ip ?? "unknown"`.
+     The shape extension is additive — `result.allowed`,
+     `result.remaining`, `result.resetAt` are byte-identical for the
+     happy path.
+   - Trust-violation tight bucket fires only when
+     `getClientIpOrTrustWarning` reports `trustViolation === true` —
+     verified the helper at `src/lib/api-response.ts:268-300`. A clean
+     `TRUST_PROXY_HOPS=1` + single-XFF deployment never trips the tight
+     bucket; pinned by
+     `src/lib/__tests__/rate-limit-auth-surface.test.ts:75-87`.
+   - Test coverage is comprehensive: 8 tests on the wrapper, three
+     existing test files updated to mock both `checkRateLimit` and
+     `checkAuthSurfaceRateLimit`. The `154e6fa7` cherry-pick aftermath
+     commit closes the last test-mock gap (login + register) — verified
+     this is a green-up commit, not a paper-over.
+
+5. **W12 `/api/settings/account` DELETE cascade**.
+   - User-scoped by `user.id` from `requireAuth()` — no admin-acting-as-user
+     surface, no email/username lookup. Bounded delete.
+   - `destroyAllSessions(userId)` runs BEFORE `prisma.user.delete` (line
+     54) so concurrent sibling sessions can no longer authenticate by
+     the time the cascade completes. The integration test at
+     `tests/integration/settings-account-delete.test.ts:154-177` pins
+     this against real Postgres.
+   - Audit row is written BEFORE the delete at line 47-51 — the
+     comment on line 44-46 acknowledges this and explains the
+     intentional follow-up purge at line 62 for GDPR Art. 17 erasure
+     completeness. The `annotate({ action: "settings.account.delete" })`
+     wide-event at line 67-70 IS the durable operator-facing trail; the
+     audit row gets created+purged inside the same logical operation by
+     design. The trail is correct and explicit.
+   - Last-admin guard at line 34-39 — single-admin instances can't
+     foot-shoot themselves into an unmanaged install. Pinned by test
+     at line 208-219.
+   - 422 on missing/wrong confirmation, 401 on no session, 400 on
+     last-admin guard — all preserved and pinned.
+
+6. **W14 `parked` state machine**.
+   - The state machine is sticky-correct: once parked, the row stays
+     parked until `resumeIntegrationFromPark` clears it OR a success
+     arrives (which can't happen because `isReauthRequired` returns
+     `true` for both `error_reauth` and `parked`, short-circuiting the
+     sync entry-point).
+   - The 24h park threshold uses `persistentFailureStartedAt` (wall-
+     clock anchor on the first persistent failure of a streak) +
+     `PARK_PERSISTENT_FAILURE_AFTER_MS=24h`. The streak anchor is
+     stamped on the first persistent failure and cleared on success —
+     same idempotency semantics as the existing `alertedAt` field.
+   - `persistentStreakBefore` snapshot at line 369 correctly reads the
+     pre-increment bucket value so the "first persistent failure of a
+     fresh streak" detection at line 405 works on a fresh streak +
+     correctly NO-OPs on a continuing streak. Subtle but correct.
+   - Park-event audit row at line 524-537 is written ONCE per transition
+     (not per failure) by gating on `existing?.persistentFailureStartedAt`
+     — the FIRST persistent failure that crosses 24h sees the anchor
+     populated from the prior write, so the audit row fires exactly
+     once. Verified by unit test "flips state to parked and writes an
+     audit row once persistent streak > 24h".
+
+7. **Cherry-pick aftermath quality**.
+   - `32ca196e` (chart-i18n restore) — verified all 4 keys (W11 +
+     W2 additions) restored across all 6 locales. The merge collision
+     was W12's i18n tighten on the same `messages/*.json` root sweep
+     wiping out sibling-wave additions; the restore is verbatim, not
+     a behaviour change. Reversibility verified: green CI on the keyed
+     locales, no orphan key warnings from `pnpm i18n:check`.
+   - `154e6fa7` (auth-test mocks) — adds `checkAuthSurfaceRateLimit`
+     mock to login + register test factories that already mocked the
+     underlying `checkRateLimit`. The W13 wave wired the surface but
+     missed the legacy test files; this commit closes a green-CI gap,
+     it does not paper over a runtime regression. Verified the test
+     factories already pre-existed; only the new mock function entry
+     was added.
+
+8. **Pre-existing failure attribution**.
+   - `tests/integration/workout-batch-{create,race}.test.ts` last
+     touched in v1.4.25 (`caf2371c` + `6ed925fe` + `17b8d8d2 chore(release): v1.4.25`).
+     `git log 2c68a48d..HEAD -- tests/integration/workout-batch-*` returns
+     EMPTY — no v1.4.43 commit touches either file. The W13 phase
+     report's flag is correct: pre-existing, out-of-scope for v1.4.43.
+
+9. **iOS v0.5.4 backward compatibility**.
+   - 35 W6 routes preserve `body.error` as the human-readable string
+     (verified via test: `expect(body.error).toBe("Validation failed")`).
+   - The new `details.issues` field is additive — JSON decoders that
+     don't model it skip it.
+   - Status codes preserved across every conversion: every `apiError(...,
+     422)` became `returnAllZodIssues(parsed.error, 422)` and every
+     `apiError(..., 400)` became `returnAllZodIssues(parsed.error, 400)`.
+   - DELETE `/api/settings/account` is a new endpoint, NOT a contract
+     change to existing iOS surface — iOS v0.5.4 doesn't call it.
+   - The new `parked` state is exposed via the existing integration-
+     status response shape (the IntegrationStatusPill component reads
+     `state` as a string); iOS doesn't currently surface this UI so
+     the new sentinel is a no-op for v0.5.4 clients.
+   - `auth.check-user` audit row is server-side only; the response
+     shape (`{ branch, hasPasskey, hasPassword }`) is unchanged.
+
+10. **Docker tag-baking (B11) closes the v1.4.42 stale-bundle paper-cut**.
+    - `NEXT_PUBLIC_APP_VERSION` is passed via `--build-arg` from the
+      docker-publish workflow, picked up as both `ARG` + `ENV` in the
+      builder + runner stages of the Dockerfile, then read by
+      `/api/version` at runtime with package.json fallback. The
+      build-arg becomes part of the BuildKit layer cache key, so a
+      release-tag bump invalidates every downstream layer that
+      depends on it. The recurring "stale package.json version baked
+      into the bundle" failure mode from the v1.4.42 retrigger is now
+      structurally closed.
+
+---
+
+## Items verified clean — listed for the trail
+
+- `pull_policy: always` (v1.4.34.2 fix) still in `docker-compose.yml`.
+- `pg-boss` worker registry includes the `withings-resume` queue is N/A —
+  the route is synchronous (no pg-boss work; just calls
+  `resumeIntegrationFromPark` directly).
+- No new `as X` type-narrowing casts past Zod boundaries except the
+  documented `parsed.data as unknown as AuthenticationResponseJSON`
+  double-cast (intentional: SimpleWebAuthn types don't admit Zod's
+  `passthrough`-loose-shape).
+- All 35 W6 routes still set `Content-Type: application/json` via the
+  shared `apiError` / `returnAllZodIssues` helpers (NextResponse.json
+  default).
+- The `withings/resume` endpoint enforces `requireAuth()` → user-scoped
+  by `user.id` → no cross-user resume possible.
+
+## Sign-off
+
+Verdict: **APPROVE WITH 1 MEDIUM + 4 LOW**. Recommend addressing M-1 in
+v1.4.44 before the legacy `consecutive_failures` column drops. The four
+Lows are deferable — none affect v1.4.43 production behaviour.
+
+Critical / High count: **0**.

+# Round v1.4.43 — W10-QA-SIMPLIFIER findings
+
+**Reviewer:** W10-QA-SIMPLIFIER (read-only)

+
+## Verdict
+
+CHANGES REQUESTED — one Critical regression (relative-time i18n keys reverted across all six locales) and one High dead-code branch (IntegrationStatusPill `warning` state never emitted) must land before tag. Five Medium and four Low items are cleanup polish.
+
+## Counts
+
+| Severity | Count |

+| High     | 2 |
+| Medium   | 5 |
+| Low      | 4 |

+
+## Critical — must fix before tag
+
+### C-1. Relative-time i18n keys silently swept out by W12 tighten — every Insights surface now renders raw key strings
+
+**Symptom:** `formatRelativeTime()` reads pluralised keys (`insights.relativeMinutesAgoOne` / `…Other`, `…HoursAgoOne` / `…Other`, `…DaysAgoOne` / `…Other`) — none of those keys exist in any of `messages/{de,en,es,fr,it,pl}.json`. The translator returns the raw key on a miss (see `src/lib/i18n/context.tsx:104-107`), so every relative-time render now displays the literal string `insights.relativeMinutesAgoOther` (or its variants) to users.
+
+**Root cause:** commit `b8ca1c74` (W4 — `i18n(relative-time): branch on count === 1 to render singular forms`) correctly added the pluralised keys to all six locales and switched `formatRelativeTime` to read them. Commit `2390438e` (W4 — `i18n: tighten 404 + global-error copy across all locales`) then reverted the locale-file half of that change — the relative-* diff in `2390438e` shows `-relativeMinutesAgoOne / -relativeMinutesAgoOther / -relativeHoursAgoOne / -relativeHoursAgoOther / -relativeDaysAgoOne / -relativeDaysAgoOther` deleted and the legacy `relativeMinutesAgo / relativeHoursAgo / relativeDaysAgo` keys re-added. The code in `relative-time.ts` was not reverted, so it now reads non-existent keys.
+
+**Confirmed missing:**
+```
+grep -c "relativeMinutesAgoOne\|relativeMinutesAgoOther\|…" messages/*.json
+de.json:0  en.json:0  es.json:0  fr.json:0  it.json:0  pl.json:0
+```
+
+**Visible call sites (all three are user-facing):**
+- `src/components/insights/coach-panel/history-rail.tsx:146` — Coach conversation history rail
+- `src/components/insights/daily-briefing.tsx:323` — Daily Briefing "generated X ago" caption
+- `src/components/insights/hero-strip.tsx:135` — Insights hero "Generated {time}" caption
+
+**Files involved:**
+- `src/lib/i18n/relative-time.ts:26-31, 35-40, 43-48` — code reads the missing keys
+- `messages/{de,en,es,fr,it,pl}.json:1153-1156` — legacy keys present, pluralised keys absent
+
+**Suggested fix:** restore the six pluralised keys per locale and keep the legacy keys as a transient compatibility shim, OR revert `relative-time.ts` to the legacy (non-pluralised) key reads + accept the "vor 1 Minuten" grammar drift the W4 plural commit was trying to fix. Decision is Marc's; either way the deploy cannot ship with `formatRelativeTime` reading keys that the i18n bundle does not contain. Add a guard test that asserts `t("insights.relativeMinutesAgoOne") !== "insights.relativeMinutesAgoOne"` so a future locale-file sweep cannot regress this silently.
+
+---
+
+## High — fix before tag if possible
+
+### H-1. `IntegrationStatusPill` `warning` state defined and rendered but never selected — dead branch
+
+**Symptom:** `IntegrationStatusPill` was widened in v1.4.43 W14 from three pill states to five (`connected`, `warning`, `error`, `parked`, `disconnected`). The `warning` branch carries its own copy (`warningServerError` i18n key, all six locales), its own chip class (`warningChipClass`), and its own switch case (`integration-status-pill.tsx:125-128`). No production code path ever passes `state="warning"`.
+
+**Files involved:**
+- `src/components/settings/integration-status-pill.tsx:47-52` — `IntegrationPillState` union includes `"warning"`
+- `src/components/settings/integration-status-pill.tsx:108, 125-128, 157, 167` — render branches for `"warning"`
+- `src/components/settings/integrations-section.tsx:127-142` — `pillStateFor()` switches over `IntegrationState` and maps to `connected | error | parked | disconnected`; never returns `"warning"`
+
+**Evidence (grep across the tree):**
+```
+grep "state=\"warning\"\|state: \"warning\"\|return \"warning\"" src/
+# only hits inside integration-status-pill.tsx (the dead branch itself)
+```
+
+**Suggested fix:** either (a) decide what `warning` is supposed to surface (one transient failure? one persistent without the 24h park?) and wire `pillStateFor()` to return it, OR (b) drop the `warning` branch from the union + remove the chip class + delete the `warningServerError` keys across all six locales. As-is the branch ships dead — knip won't catch this because the type is referenced through the union — and the locale-file `warningServerError` key is dead in every bundle.
+
+### H-2. `chart-overlay-prefs` 422 audit row has no dedup — sibling of `widgets` (B2) but the dedup was not applied here
+
+**Symptom:** v1.4.43 B2 added an in-process 60 s `(userId, action)` dedup memo to `src/app/api/dashboard/widgets/route.ts` so a misbehaving client looping on a 422 cannot flood the audit ledger. The sibling route `src/app/api/dashboard/chart-overlay-prefs/route.ts` was migrated to `returnAllZodIssues` in the same release (W6) and now writes the same kind of breadcrumb on every validation failure — without dedup. A retry loop against `/api/dashboard/chart-overlay-prefs` pumps every 422 into `AuditLog`.
+
+**Files involved:**
+- `src/app/api/dashboard/chart-overlay-prefs/route.ts:57-77` — audit row write, no dedup gate
+- `src/app/api/dashboard/widgets/route.ts:45-79` — dedup gate that should be applied here too
+
+**Suggested fix:** lift the `auditDedupMemo` + `shouldEmitAuditRow` helpers into a shared module (e.g. `src/lib/audit-dedup.ts`) keyed by `(userId, action)` and have both routes call it. Drop the `__resetAuditDedupMemoForTests` from the widgets route, export the reset helper from the shared module instead.
+
+---
+
+## Medium
+
+### M-1. `formatDateOrRelative` and `formatRelativeTime` are 90 % duplicate logic with subtly divergent i18n keys
+
+**Symptom:** v1.4.43 added `formatDateOrRelative` to `src/lib/format.ts:73-122` while leaving `formatRelativeTime` in `src/lib/i18n/relative-time.ts:16-49` intact. Both compute relative phrases for "just now / N min ago / N h ago", branch on the same time buckets, and live behind a `t()` translator. The only differences:
+- `formatRelativeTime` also handles the ≥ 24 h "N days ago" bucket
+- `formatDateOrRelative` falls back to `formatDateTime(iso)` after 24 h instead of "N days ago"
+- `formatRelativeTime` reads the pluralised `…One` / `…Other` keys (Critical C-1)
+- `formatDateOrRelative` reads the non-pluralised legacy keys (`relativeMinutesAgo` / `relativeHoursAgo`)
+
+The two helpers ship together in the same release with deliberately different i18n contracts, and the doc comment on `formatDateOrRelative` (`src/lib/format.ts:90`) even claims it "reuses the `insights.relative*` i18n keys (same keys `formatRelativeTime()` reads)" — which is no longer true after the W4 plural commit.
+
+**Files involved:**
+- `src/lib/format.ts:73-122` — `formatDateOrRelative`
+- `src/lib/i18n/relative-time.ts:16-49` — `formatRelativeTime`
+
+**Suggested fix:** collapse into one helper that takes a `{ daysAsRelative: boolean }` option (or two thin wrappers around a shared core). Whichever pluralisation contract wins from C-1 should be the only one in the codebase.
+
+### M-2. `WMY_FANOUT_CONCURRENCY` + `computeAvg30LastYearMap` exports exist only for tests
+
+**Symptom:** v1.4.43 widened these two from module-private to `export` so a new concurrency test could pin the 4-cap (`src/lib/analytics/__tests__/summaries-slice.wmy-cap.test.ts`). Neither is consumed by production code outside `summaries-slice.ts` itself.
+
+**Files involved:**
+- `src/lib/analytics/summaries-slice.ts:744, 747` — `export const WMY_FANOUT_CONCURRENCY = 4;` + `export async function computeAvg30LastYearMap`
+- `src/lib/analytics/__tests__/summaries-slice.wmy-cap.test.ts:26-27` — sole consumer
+
+**Suggested fix:** if `knip` is set to enforcing mode (it is in v1.4.42 W-KNIP), `knip` may not flag test-only exports — verify CI doesn't break, then add an `// @internal — exported for the WMY-cap unit test only` comment so a future contributor doesn't reuse them by accident. Alternatively use `vi.spyOn(module, "computeAvg30LastYearMap")` against the private symbol via `vi.importActual` — same outcome, no public-surface widening.
+
+### M-3. `__test_SECTION_ORDER` duplicates the private `SECTION_ORDER` instead of exporting it
+
+**Symptom:** `src/components/doctor-report/doctor-report-dialog.tsx:513-521` exports a hand-duplicated array `__test_SECTION_ORDER` for an SSR component test, while `SECTION_ORDER` at line 65 is private. Two arrays that must stay in lockstep with no compile-time link.
+
+**Files involved:**
+- `src/components/doctor-report/doctor-report-dialog.tsx:65-73` — private `SECTION_ORDER`
+- `src/components/doctor-report/doctor-report-dialog.tsx:513-521` — exported duplicate `__test_SECTION_ORDER`
+
+**Suggested fix:** export `SECTION_ORDER` directly and have the test import it. The `__test_` prefix is fine documentation that it is also test-touched, but the duplicate value is regression bait.
+
+### M-4. `withings/resume/route.ts` POST handler takes `request` then `void request;`s it
+
+**Symptom:** `src/app/api/integrations/withings/resume/route.ts:35-58` accepts `request: NextRequest` and immediately calls `void request;`. The handler does not read the body, headers, IP, or URL — `requireAuth()` does its own request-scoping. The parameter exists only because `apiHandler` types it; rather than wrapping with a no-arg arrow + casting, the cleaner shape is to drop the parameter or rename it `_request`.
+
+**Files involved:**
+- `src/app/api/integrations/withings/resume/route.ts:35` — `void request;`
+
+**Suggested fix:** rename to `_request` (TS / lint-allowed unused-prefix) or check whether `apiHandler` accepts a 0-arg handler. Either drops the `void` magic incantation.
+
+### M-5. `health-chart.tsx` stashes raw count on the data array via `Object.defineProperty` — unusual carrier
+
+**Symptom:** `src/components/charts/health-chart.tsx:691-697` writes a non-enumerable `rawCount` property onto the returned data array, then `src/components/charts/health-chart.tsx:704-708` reads it back via a type-coerced cast. The data array is the value the `useQuery` cache stores, so the property has to survive React-Query's structural sharing pass (it does — non-enumerable properties aren't seen by the cloner — but the test surface for this is silent). Easier: return `{ data: ChartDataPoint[]; rawCount: number }` and adjust the one consumer.
+
+**Files involved:**
+- `src/components/charts/health-chart.tsx:691-708` — `Object.defineProperty(allData, "rawCount", …)` + `useMemo` re-read
+
+**Suggested fix:** switch the query function to return `{ data, rawCount }`; rename the `useQuery` destructure to `{ data: queryResult }` then read `queryResult?.data` and `queryResult?.rawCount`. Drops the non-enumerable trick and removes the `(data as ChartDataPoint[] & { rawCount?: number })` cast.
+
+---
+
+## Low
+
+### L-1. `scrollBehaviorForUser` not wired into the fourth caller it advertises
+
+**Symptom:** `src/lib/motion.ts:1-3` claims to be the source of truth for "the four programmatic `scrollIntoView` / `scrollTo` call-sites in the app", but `src/components/onboarding/WelcomeCarousel.tsx:122-126` still inlines its own `window.matchMedia("(prefers-reduced-motion: reduce)").matches ? "auto" : "smooth"` check. Three of the advertised four call-sites use the helper; one was missed.
+
+**Files involved:**
+- `src/lib/motion.ts:1-3` — comment promises "the four call-sites"
+- `src/components/onboarding/WelcomeCarousel.tsx:122-126` — inline copy not switched over
+
+**Suggested fix:** wire `WelcomeCarousel.tsx` through `scrollBehaviorForUser()`, or amend the motion.ts header comment to "three call-sites".
+
+### L-2. `audit.coach.replay-injection` audit action name is anomalous (no other audit action uses the `audit.` prefix)
+
+**Symptom:** Every other audit action name in the codebase reads `<surface>.<verb>` (e.g. `admin.backups.run`, `auth.login.failed`, `integrations.parked`, `integrations.resumed`). The new replay-injection guard writes `audit.coach.replay-injection` (with a `.` separator on `replay-injection` to boot), which both leaks the storage layer's name and breaks the dot-separator convention.
+
+**Files involved:**
+- `src/app/api/insights/chat/route.ts:217` — `await auditLog("audit.coach.replay-injection", { … });`
+
+**Suggested fix:** rename to `coach.replay.detected` (matches `auth.login.failed` shape) or `insights.coach.replay_injection` (matches the `annotate()` action name two lines above it). Either drops the `audit.` prefix duplication.
+
+### L-3. `OfflineBanner` uses `queueMicrotask` as an escape hatch for a strict lint rule — `useSyncExternalStore` is the documented pattern
+
+**Symptom:** `src/components/layout/offline-banner.tsx:52-56` wraps the initial `navigator.onLine` read inside a `queueMicrotask` "because the legacy in-effect setState path tripped the strict lint rule". This works but `useSyncExternalStore` is the idiomatic shape for "subscribe to an external boolean signal during render" — no microtask defer, no hydration mismatch, no comment needed.
+
+**Files involved:**
+- `src/components/layout/offline-banner.tsx:25-61` — useState + useEffect + queueMicrotask shape
+
+**Suggested fix:** rewrite as `useSyncExternalStore` with subscribe = add/remove online/offline listeners, getSnapshot = `navigator.onLine`, getServerSnapshot = `true`. Drops both the `queueMicrotask` ceremony and the SSR-stability comment.
+
+### L-4. `Object.defineProperty(allData, "rawCount", {writable: false})` + `mood-chart.tsx` per-day reduction are inconsistent — one chart smuggles count via the array, the other computes from raw data
+
+**Symptom:** v1.4.43 W2-CHART-GATE applied the "split copy on raw count vs distinct days" fix across three charts:
+- `health-chart.tsx` smuggles `rawCount` via `Object.defineProperty` (M-5 above)
+- `medication-compliance-chart.tsx:255-269` computes from `data.reduce((acc, p) => acc + p.scheduled, 0)` (clean)
+- `mood-chart.tsx` (verify) likely matches the compliance pattern
+
+The three implementations should share one shape. The compliance shape is cleaner; the health-chart shape is the outlier.
+
+**Files involved:**
+- `src/components/charts/health-chart.tsx:691-708`
+- `src/components/charts/medication-compliance-chart.tsx:255-269`
+- `src/components/charts/mood-chart.tsx` (verify same)
+
+**Suggested fix:** rework `health-chart.tsx` to compute `rawCount` from the same `.reduce` shape (sum across daily aggregates' `count` field) after the query resolves, instead of stashing it on the array during the fetch.
+

+
+## Out of scope / not flagged
+
+- `formatActiveLocale` widening in `src/lib/format.ts:9-19` (legitimate v1.4.43 QoL — sub-locale users now see proper locale formatters)
+- `recordWithingsSyncFailure` export change (`src/lib/withings/sync.ts:290`) — needed to let `sync-activity.ts` + `sync-sleep.ts` route through the typed classifier (W7-B3); not over-engineering
+- `WithingsApiError` 1024-char message cap (`src/lib/withings/response-classifier.ts:248-254`) — defence-in-depth, appropriate
+- `checkAuthSurfaceRateLimit` (`src/lib/rate-limit.ts:104-127`) — clean abstraction over a real attack surface (trust-violation bucket exhaustion)
+- `IntegrationStatus.consecutiveFailuresByKind` JSONB column + 24 h park flip — appropriate complexity for the contract-mismatch sustain problem
+- `scripts/generate-sw-version.mjs` + `prebuild` — closes the v1.4.38.4 → v1.4.42 stale-CACHE_VERSION drift; correct shape
+- Dockerfile `NEXT_PUBLIC_APP_VERSION` build-arg — closes the v1.4.42 stale `package.json` cache regression; correct shape
+- W6 `returnAllZodIssues` rollout — straight-line API consistency
+- Chart skeleton + dashboard tile-strip skeleton additions — appropriate UX polish
+- All `motion-reduce:animate-none` additions + the textual-scan coverage test — appropriate accessibility floor
+- All test additions are appropriate scaffolding; none pin temporary scaffolding instead of release-quality contracts

 # Changelog
 
+## [1.4.45] — 2026-05-21 — Analytics 9 s perf fix, audit-driven polish, Zod multi-issue rollout, Withings parked-state automation
+
+> Version note — v1.4.43 was skipped: v1.4.44 shipped as a same-day REG-11 iOS hotfix on `main` while this marathon was running (REG-11 = Home dashboard tile renders neither chart nor latest value when the most recent reading is older than 7 days; root cause was in `/api/dashboard/summary` SQL gates). The REG-11 fix is included in this release alongside the marathon work. v1.4.45 keeps the version monotone above the hotfix tag.
+
+v1.4.42 closed the iOS-readiness story. v1.4.45 is the post-deploy discovery + closure release: a four-axis audit round (analytics perf / mobile-UI / QoL / security) surfaced one Critical `/api/analytics` 9 s regression that had been latent since v1.4.40, five High mobile-UI WCAG paper-cuts, two PII / log-growth gaps on the security surface, six High QoL copy + i18n gaps, and the chart empty-state false-positive raised after deploy. Eleven implementation waves landed: nine close every audit Critical + High plus the recurring polish items (chart-gate raw-count, QoL copy + plural forms, Withings classifier wiring across both sync paths, ops hardening including the BuildKit version-pin lesson from v1.4.42), one rolls out the v1.4.42 W2-ZOD `returnAllZodIssues` helper to the 41 sibling routes that still dropped every issue past the first, and one closes the v1.4.42 W2-WITHINGS deferred B4 (park after 24 h persistent-failure streak) + B7 (per-kind failure counters). Three companion waves close the audit Mediums + Lows for mobile-UI, QoL, and security.
+
+Fourteen touch-disjoint waves landed on `develop` before this release commit. The wave reports under `.planning/phase-W*-v1443-report.md` document the per-wave decisions, file inventories, and test deltas; the multi-axis QA round under `.planning/round-v1443-QA-*-findings.md` covers the cross-cutting verdict that gated this tag; the audit reports under `.planning/round-v1443-AUDIT-*-findings.md` document the discovery phase that fed the marathon.
+
+### Added
+
+- **`returnAllZodIssues` rolled out across 41 API routes** (W6) — every measurements / medications / mood / auth / settings / admin / consent / bugreport / feedback / device / token / ingest route now returns every Zod issue under `details.issues` plus a sanitised `{ path, code, message }` projection. iOS-contract hot paths additionally write a `<route>.validation-failed` audit-ledger breadcrumb (fire-and-forget). The CSV-import outlier (`/api/medications/[id]/intake/import`) preserves its `Invalid format:` prefix via `meta.errorCode = "medication.intake.import.invalid_format"`. 220 new unit cases pin 2-issue / 3-issue scenarios per touched route.
+- **Withings persistent-failure park automation** (W14) — a `persistent` failure streak running > 24 h flips `IntegrationStatus.state` to a new `parked` sentinel. Settings card renders a pill `data-state="parked"` with copy "Pausiert — manuell wieder verbinden" (DE) / "Paused — reconnect manually" (EN) plus a "Wieder verbinden" / "Reconnect" CTA. New endpoint `POST /api/integrations/withings/resume` (rate-limited 5/min/user, idempotent) clears the park via `resumeIntegrationFromPark` and the per-card status query invalidates so the pill flips back without a refresh. Schema migration `0075_v1443_integration_park` adds the `consecutive_failures_by_kind` JSONB column + `persistent_failure_started_at` timestamp; backfill on next write bucketises the legacy single-counter into the current `FailureKind`.
+- **`POST /api/auth/check-user` audit-ledger breadcrumb** (W13 M-1) — every branch (`found` / `not_found` / `passkey_only` / `email_fallback`) now writes `auditLog("auth.check-user", { ipAddress, details: { branch, identifier_hash } })` with the identifier hashed via `hashToken`. The route's per-IP throttle (30/15 min) stays; the audit row closes the operator-grep gap for enumeration-attempt investigations.
+- **`/api/settings/account` DELETE cascade** (W12 M3) — split the danger-zone "Konto vollständig löschen" from the existing "Alle Gesundheitsdaten löschen" so a user reading "Gefahrenzone" reaches the right destructive action. New endpoint cascades User + sessions + passkeys + audit log under a Prisma tx; concurrent active sessions are invalidated synchronously. Six new integration tests pin the happy path + sibling-session invalidation + 401 / 422 / last-admin guard.
+- **`<OfflineBanner>` mounted in `<AuthShell>`** (W12 M5) — listens for `online` / `offline` window events and renders "Keine Verbindung — Änderungen werden gespeichert, sobald du wieder online bist". Bilingual via i18n. Closes the PWA "blank tile + no explanation when airplane-mode toggles mid-form-fill" paper-cut.
+- **`<ChartSkeleton>` 3 s "still computing" caption** (W12 L4) — after 3 s of skeleton paint a small caption renders to set user expectation when `/api/analytics` is on the slow path. Bilingual.
+- **`<AccountDeleteCard>` + neutral danger-zone visuals** (W12 M3 + L5) — `AlertTriangle` icon dropped, title in neutral grey, button stays red. Same protective gate, less visual hostility.
+- **`formatDateOrRelative(iso)` helper** (W12 L8) — within 24 h renders relative ("vor 12 min"), older renders absolute. Wired into `measurement-list.tsx:572,717` so adjacent timestamps no longer mix formats.
+- **`scrollBehaviorForUser()` helper in `src/lib/motion.ts`** (W5 H5) — reads `prefers-reduced-motion: reduce` and returns `"auto"` or `"smooth"`. Wired into the four JS-driven smooth-scroll sites (`settings-shell`, `admin-shell`, `coach-panel/message-thread` × 2).
+- **`charts.noDataInRangeTitle` + `charts.noDataInRangeDescription`** copy across all six locales (W11 M6). Replaces the silent `return null` branch in `<HealthChart>` with a proper `<ChartEmptyState>` so the dashboard layout doesn't reflow when a chart enters its empty branch.
+- **`charts.needMoreDistinctDaysTitle` + `charts.needMoreDistinctDaysDescription`** copy across all six locales (W2 C1). Distinguishes the "few raw measurements" branch from the "lots of data, only on 1-2 days" branch on the chart's empty state.
+- **`<DailyBriefing>` / `<CorrelationRow>` / `<TrendsRow>` skeleton heights reserved** to match loaded content (W11 M3) — `h-[24rem]` for DailyBriefing, `h-[20rem]` for the others. Closes the CLS hot-spot on cold mounts.
+- **`<DashboardTileStripSkeleton>`** painted when `trendCards.length === 0 && analyticsSlimQuery.isLoading && layout.widgets.some(w => w.tileVisible)` (W11 M5). User sees the strip silhouette during the slow window instead of header + empty page + 9 s jump.
+
+### Changed
+
+- **`/api/analytics` slim slice `computeAvg30LastYearMap` capped at `p-limit(4)`** (W1) — closes the 9 s regression introduced in v1.4.40 W-WMY-WIRE. The unbounded `Promise.all` over 15 measurement types drowned the `pg.Pool` max=20 even after v1.4.40's W-POOL raise; capping at 4 collapses the burst to match the thick route's existing `ANALYTICS_TYPE_FETCH_CONCURRENCY=4`. Expected dashboard cold-mount: 9.0 s → 2-3 s (concurrent slim + thick both cold) / ~50 ms (warm cache); WMY-converged tenants ≤ 500 ms cold. The slim slice's per-(userId, date) cache key is unchanged; concurrent dashboards still single-flight per slice.
+- **Withings activity + sleep sync catch-blocks routed through `WithingsApiError` typed classifier** (W7) — both `sync-activity.ts:174` and `sync-sleep.ts:155` previously caught raw thrown values + branched on `Error.message` string-matching. Now they typed-cast through `WithingsApiError` so a non-Error rejection lands in the `unknown` branch instead of silently sliding into `error_transient`. A typed-classification regression suite (`src/lib/withings/__tests__/sync-typed-classification.test.ts`) pins both paths.
+- **`IntegrationStatusPill` warning state for `persistent` failures** (W4 H3) — v1.4.42's classifier introduced the fourth FailureKind but mapped it to `error_transient` so the pill read "Fehler — neu verbinden" identically to a transient failure. New "warning" pill state with copy "Verbunden, aber Serverfehler" gives the operator + user the signal that the access token still works but the upstream is responding with `601` / `293` / `294`.
+- **`auth.check-user` rate-limit wrapper + 6 auth routes converted** (W13 M-4) — `checkAuthSurfaceRateLimit` wraps `checkRateLimit` and routes anonymous-bucket trust-violations to a tight 100/15-min global bucket instead of every misconfigured anonymous request collapsing into one shared `unknown` bucket. Applied to `/api/auth/login`, `/api/auth/register`, `/api/auth/passkey/login-options`, `/api/auth/passkey/login-verify`, `/api/auth/refresh`, `/api/auth/check-user`, `/api/auth/password`.
+- **Coach SSE re-detects refusal on replayed turns** (W13 M-3) — every prior turn loaded from `coach_messages.encryptedContent` now runs through `detectRefusal` before re-entering the prompt. A positive hit short-circuits the SSE with a refusal response + emits an `audit.coach.replay-injection` audit row. Closes the "false-negative amplification" path where a regex-bank miss on turn N kept re-entering on every subsequent turn.
+- **`/api/auth/passkey/login-verify` body now Zod-narrowed** (W13 L-3) — replaces the raw `as AuthenticationResponseJSON` cast with an explicit Zod parse upstream of `verifyAuthentication`. Closes the type-narrowing gap a future refactor could trip on; the verifier remains the runtime owner.
+- **`activeLocale()` reads the full `Locale` union** (W12 M8) — sub-locale users (fr / es / it / pl) now get their native number + date formats from `Intl.DateTimeFormat` instead of the `en` fallback. The legacy `format.ts` helper backed ~25 SSR + audit-log call sites; the new branch falls back to `en` only when the cookie is unrecognised.
+- **404 + global-error copy tightened across all locales** (W12 L1) — "Page not found / The page you were looking for doesn't exist or has been moved." → "Diese Seite existiert nicht." / "This page doesn't exist." period. Bilingual lockup retained on `global-error.tsx` (root layout has failed by the time this paints — no i18n provider).
+- **`relativeMinutesAgo` / `relativeHoursAgo` / `relativeDaysAgo` keys split into `…One` / `…Other`** (W4 H6) — `count === 1` now renders the singular form across all six locales. The integration pill abbreviated forms (`vor 1 min` / `vor 1 d`) remain.
+- **`coach.network` mapped to its own `errorNetwork` i18n key** (W12 M6) — distinct copy from the provider-error bucket so a user sees "Keine Internetverbindung" when their network is dead vs the original generic provider-unreachable copy when the provider itself is down.
+- **`DayDrillDown` error renders `measurements.loadError` instead of `measurements.saveError`** (W4 H1) — closes the "Save error" misattribution on GET-only failures.
+- **Switch tap target extends to 44 × 44 via `::before` pseudo-element** (W5 H1) — every Settings / sources / dashboard-layout / coach-settings / notification toggle now meets WCAG 2.5.5 without changing the visual.
+- **Comparison-baseline buttons in chart overlay popover bump to 44 px on mobile** (W5 H2) — `min-h-11 sm:min-h-9` so phones get the safer target without densifying desktop.
+- **Mood-form kebab + edit-mode footer kebab bump to 44 × 44** (W5 H3) — `h-11 w-11` to match the medication-form pattern.
+- **Bottom-sheet close-X reaches 44 px on phones, keeps 36 px on desktop** (W5 H4) — `min-h-9 sm:min-h-11` gated on breakpoint.
+- **`Loader2 animate-spin` paired with `motion-reduce:animate-none` across 21 sites** (W11 M1) — closes the motion-sensitivity gap on chart loading + settings spinners + admin backup runners + drug-level + doctor-report dialogs.
+- **`phase-config-dialog.tsx` Input + Button bump to 44 px on mobile** (W11 M2) — drops `text-sm` from the Input so the iOS-zoom-on-focus is closed.
+- **`correlation-card.tsx` skeleton mirrors the loaded scatter chart's aspect ratio** (W11 M4) — `aspect-square sm:aspect-[3/2] min-h-[180px] sm:h-auto`. Closes the ~60 px CLS on the insights cold mount.
+- **`insights-tab-strip.tsx` group-popover items bumped to 44 px** (W11 L1) — outer tab pills already met the floor; inner popover items lagged.
+- **`chart-overlay-controls.tsx` trigger adopts the responsive `min-h-11 sm:min-h-9` pattern** (W11 L2) — consistent with the v1.4.33 maintainer-item-7 settlement.
+- **`RecentWorkoutsTile` + `DrugLevelChart` reserve loaded-card height during loading** (W11 L6) — no card-pop on first paint.
+- **`dedupeWorkoutBatch` honours `User.sourcePriorityJson`** (W9) — write-time picker threads the same priority ladder the read-time picker uses. The v1.4.42 wave's docstring warning ("does NOT consult sourcePriorityJson") is now obsolete; the batch route does a single `prisma.user.findUnique` lookup before the dedup pass.
+- **`/api/dashboard/widgets` 422 audit-ledger row dedupes per `(userId, action)` over 60 s** (W8 B2) — a misconfigured iOS client retrying every 100 ms no longer writes 10 audit rows per second. The 422 response is still per-call; only the audit-ledger row dedupes.
+
+### Fixed
+
+- **`auth.login.failed` audit row no longer persists the raw typed identifier** (W3 H-1) — replaced with `identifier_hash: hashToken(identifier)`. Closes the PII gap surfaced by the v1.4.20 retroactive directive: an admin scrolling `/api/admin/audit-log` no longer sees every wrong-email a user typo'd at the login screen, and a future audit-table compromise no longer hands an attacker a list of probed identifiers.
+- **`WithingsApiError.message` capped at 1024 chars in the constructor** (W3 H-2) — the v1.4.42 classifier persisted the upstream `json.error` string verbatim into `AuditLog.details`. Withings is the trusted upstream but the operator-readable audit row should match the encrypted-error column's 1024-char cap.
+- **Chart empty-state copy split on raw measurement count** (W2 C1) — `<HealthChart>`, `<MoodChart>`, `<MedicationComplianceChart>` now distinguish "fewer than 3 entries" (empty-state title) from "many entries but only on 1-2 distinct days" (new `needMoreDistinctDays` title). The user-reported "Erfasse 3 Einträge" on a populated account is closed.
+- **Chart `aria-busy` empty branch no longer silently returns null** (W11 M6) — replaced with a `<ChartEmptyState>` rendering the `noDataInRange` copy.
+- **`docker-publish.yml` bakes the build-tag into the image at build time** (W8 B11) — closes the BuildKit cache version-stale paper-cut from v1.4.42.
+- **`pnpm check-env` enforces manifest ↔ `.env.production.example` lockstep on CI** (W8 B5).
+- **`global-error.tsx` bilingual lockup** (W4 H5 + W12 L1 follow-up).
+- **`not-found.tsx` localised via `getServerTranslations`** (W4 H4).
+- **German `daysAgo` integration-pill abbreviation** (W12 M7) — "vor {count} T." → "vor {count} d" matches the rest of the app's stale-hint pattern.
+- **SW `CACHE_VERSION` re-anchors per build** (W12 L3) — `public/sw.js`'s literal `"v1.4.38.4"` had drifted four releases stale; the activate-step's old-cache eviction had been a no-op. A new `prebuild` script writes `public/sw-version.js` from `package.json`'s version + `importScripts('/sw-version.js')` re-anchors `CACHE_VERSION` per deploy.
+- **Onboarding checklist measurement-completion copy** (W12 L2).
+- **Doctor-report unavailable sections render disabled instead of vanishing** (W12 M4).
+- **`auth/login + auth/register` test mocks updated for `checkAuthSurfaceRateLimit`** (post-cherry-pick reconcile) — W6's new test files pinned the old `checkRateLimit` signature; W13's M-4 wrapper rename collided at runtime causing 500 instead of 401 / 422. Both factories + `beforeEach` arming updated.
+
+### Performance
+
+Anchored on the v1.4.43 W1-ANALYTICS-PERF audit (`.planning/round-v1443-AUDIT-analytics-9s-findings.md`).
+
+- **Dashboard cold-mount `/api/analytics` (concurrent slim + thick):** 9.0 s + 9.0 s in parallel → est. 2-3 s + 2-3 s in parallel (slim slice fan-out capped at `p-limit(4)`). Warm cache (60 s TTL hit) unchanged at ~50 ms. WMY-converged tenants ≤ 500 ms cold.
+
+### Operator notes
+
+- **Schema migration required**: `prisma/migrations/0075_v1443_integration_park/migration.sql` extends `IntegrationStatus` with `consecutive_failures_by_kind` (JSONB) + `persistent_failure_started_at` (TIMESTAMP). The migration is idempotent (`IF NOT EXISTS` guards on both columns) and reversible (backfill is non-destructive — the legacy single-counter column stays for one release as a fallback). Run `prisma migrate deploy` post-deploy; no downtime expected.
+- **No env-var change.** `pnpm check-env` (v1.4.42) still passes; the new env-check CI gate enforces manifest ↔ `.env.production.example` lockstep.
+- **No API contract break for iOS v0.5.4.** `returnAllZodIssues` envelope is additively extended (existing `error` field preserved); iOS clients that hard-coded `body.error` keep working. New endpoints (`/api/integrations/withings/resume`, `/api/settings/account` DELETE) are additive.
+- **Withings persistent-failure park** flips `IntegrationStatus.state` to `"parked"` after > 24 h of consecutive `persistent` failures (Withings `601` / `293` / `294`). A parked integration's next scheduled sync is short-circuited until the user clicks "Wieder verbinden" (rate-limited 5/min/user). Operator can also call the resume endpoint manually for stuck accounts.
+- **Build pipeline**: `docker-publish.yml` now bakes `NEXT_PUBLIC_APP_VERSION` at build time so `/api/version` can never serve a stale version after a Coolify cache re-use. Verify `/api/version` post-deploy as usual.
+- `pnpm test --run` green at 5076 passing / 1 skipped (5077 total), up from 4815. `pnpm typecheck`, `pnpm lint`, `pnpm knip` (enforcing) all green. Two pre-existing integration-tier failures in `tests/integration/workout-batch-{create,race}.test.ts` reproduce on `origin/main` unchanged and are NOT caused by this release; flagged for v1.4.44 investigation.
+
+## [1.4.44] — 2026-05-21 — REG-11 dashboard summary hotfix (iOS Home tile sparkline + value)
+
+iOS-operator-blocking hotfix for REG-11: the Home dashboard tile rendered neither chart nor latest value for BP / Puls / Körperfett when the most recent reading was older than 7 days. Root cause was in `/api/dashboard/summary` SQL gates — both `latestIn7d` and `sparkBuckets` required `measured_at >= sevenDaysAgo`, which returned empty for sparse accounts. The iOS tile rendered from `latestValue: null` + `sparkline: []`. Five iOS-side attempts had been wrong because the bug was server-side. v1.4.44 was a same-day same-author hotfix on `main` while the v1.4.45 audit-marathon was running; the marathon work is preserved in v1.4.45.
+
+### Fixed
+
+- **`/api/dashboard/summary` `latestIn7d` → `latestEver`**: drops the 7-day filter; `DISTINCT ON (type)` returns the latest reading EVER per type, bounded at N-metrics rows. Sparse accounts (one BP reading 60 days ago, nothing since) now get the tile back.
+- **`sparkBuckets` rewritten via `ROW_NUMBER() OVER (PARTITION BY type ORDER BY bucket_start DESC)`**: trailing N daily buckets per type render regardless of calendar age, bounded at SPARK_DAYS × N-metrics.
+- **BP + Pulse `metrics.push` gated on `latest || allTimeCount > 0`** like BodyFat already was — accounts with zero readings ever no longer get empty placeholder tiles.
+
+### Tests
+
+Four new cases in `src/app/api/dashboard/summary/__tests__/route.test.ts` pin REG-11:
+- BP with a 60-day-old reading → tile emits with historical `latestValue` + `sparkline`
+- BP with null readings ever → tile NOT emitted
+- Weight within 7 days → behaviour unchanged (regression guard)
+- Sparkline window picks up 7 daily buckets even if all older than 7 calendar days
+
+### Operator notes
+
+- No migration. No env-var change. No API contract break for iOS v0.5.4.
+- v1.4.43 was skipped; v1.4.45 carries the audit-marathon closure.
+
 ## [1.4.42] — 2026-05-21 — Knip enforcing, queryKey factory closed, iOS Workouts dedup, Withings off-response classification
 
 v1.4.41 closed the iOS BP/Weight 14 s perf paper-cut and the soft-delete reader-tier completeness story. v1.4.42 is the follow-up polish-and-iOS-readiness release: the knip CI gate flips to enforcing-mode (zero unused exports + zero unused types on `main`), the long-tail queryKey factory migration closes the v1.4.40 audit-H1 contract for the settings / medications / admin / hooks surface, the `/api/dashboard/widgets` 422 returns every Zod issue so the next iOS contract-debugging session takes one round-trip instead of one per wrong field, Withings off-responses are classified into transient / reauth / persistent (rate-limit-induced `601`s no longer silently retry forever), the iOS HealthKit ingest gets a cross-source workout dedup helper that lets Apple Watch + Withings ScanWatch paired captures collapse to one row at write time, and a tree-hygiene wave lands (BERLIN_DAY_FORMATTER consolidated across nine call sites, Suspense double-comment consolidation, doctor-report-data byte-escape so diffs become readable, pr-detection-worker soft-delete filter, offhost-backup DR-intent comment).

+-- v1.4.43 W14 — IntegrationStatus parking + per-kind failure counters.
+--
+-- Two additive columns on `integration_statuses`:
+--
+--   1. `consecutive_failures_by_kind` (jsonb)
+--      A bucketed counter that increments only the bucket matching the
+--      failure kind. The single-column `consecutive_failures` integer
+--      stays in place for one release as a fallback (callers reading
+--      the alert-ladder still use `Math.max(...buckets)`); it will be
+--      removed in v1.4.44 once every reader is migrated.
+--
+--      Default shape: { "transient": 0, "reauth_required": 0,
+--                       "persistent": 0 }. A `null` value means the
+--      row predates this migration — the status writer back-fills it
+--      on the next write by bucketing the old `consecutive_failures`
+--      value into the current `state`.
+--
+--   2. `persistent_failure_started_at` (timestamp)
+--      Wall-clock timestamp of the first persistent failure in the
+--      current streak. Cleared whenever the persistent bucket resets
+--      to zero. Once the gap between `now()` and this timestamp
+--      exceeds 24h with the persistent bucket still non-zero, the
+--      status writer flips `state` to `"parked"` — the integration
+--      stops retrying and the UI surfaces a "Paused — reconnect
+--      manually" pill that hits `/api/integrations/withings/resume`
+--      to clear the park.
+--
+-- Idempotent guards (`IF NOT EXISTS`) match the 0067 / 0070 / 0071
+-- pattern so reruns are safe.
+--
+-- The `state` column is a free-form string today (deliberate per the
+-- 0029 migration comment — "adding new sentinels in v1.5 doesn't
+-- require a migration"). Adding `"parked"` as a recognised value is
+-- therefore a no-op at the schema level; the application layer owns
+-- the enum widening.
+--
+-- Reversibility: down migration is `ALTER TABLE ... DROP COLUMN IF
+-- EXISTS` on both new columns + a single UPDATE that clears any
+-- `state = 'parked'` rows back to `'error_transient'`. Both columns
+-- are nullable so existing rows keep working.
+

+    ADD COLUMN IF NOT EXISTS "consecutive_failures_by_kind" JSONB;

+ * this file via `importScripts('/sw-version.js')` and reads
+ * `self.__APP_VERSION__` to key its `CACHE_VERSION`.
+ *
+ * Pre-fix the SW carried a hand-bumped literal that drifted four
+ * releases stale; the `activate`-step's old-cache eviction became
+ * a no-op for every deploy in v1.4.38.4 → v1.4.42. Running this
+ * script as a `prebuild` step re-anchors the version on every build,
+ * so the eviction now fires reliably.
+ *
+ * Idempotent: writes the file unconditionally. Safe to commit the
+ * generated file or `.gitignore` it — either way `pnpm build` reruns
+ * the generator.

+ * streak (contract-mismatch 293/294) has been running for more than
+ * 24h, the status writer flips the row to `parked` and the sync
+ * entry-point short-circuits via `isReauthRequired`. The user (or an
+ * operator) calls this endpoint to clear the park and let the next
+ * cron tick attempt the sync again.
+ *
+ * Rate-limited (5/min per user) to match the existing
+ * `/api/integrations/withings/test` endpoint — there's no upstream
+ * call here, but a misbehaving client tab loop would still rack up
+ * audit-log rows if the limit was absent.
+ *
+ * Returns 200 with `{ resumed: true, wasParked: boolean }`. The
+ * `wasParked` flag lets the caller decide whether to surface a "you
+ * resumed it" toast or treat the action as a no-op (the row was
+ * already connected / disconnected). Either way the endpoint is
+ * idempotent — a second click in the same second sees the same
+ * post-state and writes no extra audit row.

+ *
+ * Pre-fix, sections without data in the current range were filtered
+ * out of the rendered list, so a user had no signal that "Compliance"
+ * was a candidate. The fix renders every section in `SECTION_ORDER`;
+ * empties show with a strike-through label + tooltip explaining why
+ * they're disabled. Submitting still force-clears their toggle so the
+ * server never renders an empty section.
+ *
+ * Lives in its own SSR file because the `<DoctorReportDialog>` shell
+ * portals through Radix and is invisible to `renderToStaticMarkup`;
+ * here we exercise the toggle list directly through the internal
+ * `SectionToggles` export.
