+# Phase W2 — Textarea primitive extraction (v1.4.47)
+
+## Goal
+Close the v1.4.43 mobile-UI audit L3 finding: six call-sites were each maintaining their own copy-pasted className with the `text-base sm:text-sm` iOS-zoom defence, drift risk on every edit. Extract a shadcn-style `<Textarea>` primitive parallel to `<Input>`, migrate the affected call-sites, lock the contract behind unit tests.
+
+## What landed
+
+### New primitive: `src/components/ui/textarea.tsx`
+Mirror of `<Input>` for multi-line input. Baked-in defaults:
+
+- **iOS zoom defence** — `text-base sm:text-sm` (16 px on mobile, 14 px on `sm+`). Safari zooms the viewport on focus when the rendered font is below 16 px and yanks the keyboard up; this defends every consumer without each site having to repeat the dance.
+- **WCAG 2.5.5 tap-target floor** — `min-h-11 sm:min-h-9` (44 px on touch, 36 px on pointer). Lets `rows={1}` consumers stay above the tap-target floor without manually overriding.
+- **`autoCapitalize="sentences"`** — free-text fields read as prose on iOS / Android by default. Caller overrides with `"none"` for code / JSON / IDs.
+- **`spellCheck={true}`** — same reasoning; caller opts out for structured input.
+- **`autoComplete="off"` + `data-lpignore` / `data-1p-ignore`** — same posture as `<Input>`: HealthLog is a health-data app, so password managers don't get to paste the user's saved password into a free-text note that we then persist server-side.
+- **`forwardRef`** so consumers can attach refs (auto-grow, focus management, …).
+- **`data-slot="textarea"`** for the shadcn convention.
+- **`cn(…)` composition** — caller className wins via tailwind-merge, defaults still apply.
+
+Plus the standard focus / aria-invalid / disabled treatment that mirrors `<Input>`.
+
+### New tests: `src/components/ui/__tests__/textarea.test.tsx`
+11 tests, all green. Locks the contract:
+
+- iOS zoom defence class present (`text-base` + `sm:text-sm`).
+- WCAG tap-target floor present (`min-h-11` + `sm:min-h-9`).
+- `autoComplete` defaults to `"off"` with the password-manager ignore attrs.
+- `autoCapitalize` defaults to `"sentences"`.
+- `spellCheck` defaults to `true`.
+- `data-slot="textarea"` attribute.
+- Caller overrides for `autoCapitalize` / `spellCheck` are honoured (JSON-paste case).
+- Caller overrides for `autoComplete` drop the ignore attrs.
+- Caller className merges via `cn()` without losing defaults.
+- `React.forwardRef` sentinel verified (sentinel-symbol check, dependency-free — no testing-library needed).
+- `rows` / `placeholder` / `maxLength` forwarded to the underlying element.
+
+## Call-sites migrated
+
+| File | Lines saved | Notes |
+| --- | --- | --- |
+| `src/app/bugreport/page.tsx:202` | -3 (comment + comment + 211-char className) | Plain free-text bug description; primitive defaults are a 1:1 fit. |
+| `src/app/medications/page.tsx:468` | -3 inline className + 2 comment | JSON paste — explicitly disables `autoCapitalize` + `spellCheck`, keeps the `font-mono` override via `className`. |
+| `src/components/medications/SideEffectsSection.tsx:467` | -3 inline className + 2 comment + 2 redundant attrs | Compact notes-row inside side-effect modal; `px-2 py-1.5` padding override preserved via `className`. Dropped the redundant explicit `autoCapitalize="sentences"` / `autoComplete="off"` (now the default). |
+| `src/components/admin/feedback-inbox-section.tsx:498` | -3 (comment + comment + 211-char className) | Admin internal-note textarea; primitive defaults are a 1:1 fit. |
+
+**Total**: ~16 lines of copy-paste removed; **852 chars** of repeated className strings eliminated.
+
+## Out of scope (intentional)
+
+- **`src/components/insights/coach-panel/coach-input.tsx:188`** — included in the audit's "6+" count, but it's a fundamentally different design (auto-grow composer card wrapped in an outer "fake input" div with its own border + focus-within ring + Dracula-purple ring on focus, transparent textarea bg, custom `max-h-[9.5rem]` cap with internal overflow). Migrating it would require nullifying nearly every primitive default (border, bg, focus-ring, min-h, padding, shadow) — net worse than the inline pattern. Left as-is.
+- `<Input>` modifications — separate concern per scope.
+
+## Quality gates
+
+- `pnpm typecheck` — green.
+- `pnpm lint` on the touched files — green (one unrelated pre-existing warning in a withings test file remains).
+- `pnpm test src/components/ui/__tests__/textarea.test.tsx` — 11/11 green.
+- `pnpm test src/components/ui/__tests__/ src/components/medications/__tests__/SideEffectsSection.test.tsx` — 43/43 green; no regression in the suites that touch the migrated files.
+- `npx prettier --check` on the touched files — clean after a `--write` pass.
+- `npx knip` — clean (no unused exports / files).
+- Full `pnpm test` — 5101 / 5104 pass; the 2 failing tests (`/api/dashboard/summary` idempotency + `/api/medications/intake` double-mint) are confirmed pre-existing (fail on origin/develop unchanged, verified via `git stash`). Not in this scope.
+
+## Branch
+
+`worktree-agent-a135dd75a71c47561` — branched from `origin/develop` (HEAD `690cfaf0`).
+
+## Files touched
+
+- **NEW** `src/components/ui/textarea.tsx` (+82 LOC)
+- **NEW** `src/components/ui/__tests__/textarea.test.tsx` (+93 LOC)
+- **EDIT** `src/app/bugreport/page.tsx` (-3 textarea LOC, +1 import)

+- **EDIT** `src/components/medications/SideEffectsSection.tsx` (-5 textarea LOC, +1 import)
+- **EDIT** `src/components/admin/feedback-inbox-section.tsx` (-3 textarea LOC, +1 import)
+
+Net: +169 LOC primitive + tests, -14 LOC inline copy-paste, with the audit's drift-risk surface area now closed behind a single contract + test file.

 # Changelog
 
+## [1.4.47] — 2026-05-22 — Audit-backlog closure: drag-to-reorder, Coach disable toggle, OAuth state nonce table, legacy column drop, primitive sweep
+
+v1.4.45 closed the v1.4.43-audit follow-up; v1.4.46 caught a same-day server reconcile (PR worker, intake auto-skip, APNS admin test). v1.4.47 is the dedicated follow-up that lands every deferred v1.4.45 audit Medium/Low plus the W14 legacy-column cleanup the v1.4.45 release scheduled for "one release later".
+
+Eight changes landed on `develop` before this release commit:
+
+- **W0** wall-clock pin on the two idempotency tests (`/api/dashboard/summary` + `/api/medications/intake`) that hard-coded `2026-05-21` and broke on the 22nd
+- **W1** drop the legacy `consecutive_failures` column on `integration_statuses` — the v1.4.45 W14 per-kind bucket migration carried the legacy integer for one release as a fallback; now removed, alert ladder reads `Math.max(...buckets)`
+- **W2** extract `<Textarea>` primitive with iOS-zoom defence + WCAG tap-target floor; sweep 4 inline call-sites (bugreport, medication JSON paste, side-effects notes, admin feedback)
+- **W3** per-user Coach disable toggle in Settings → Insights; survives `flags.coach` (admin) gate at all five mount points; new `disableCoach` column + audit-logged PATCH endpoint
+- **W4** dashboard widget drag-to-reorder via `@dnd-kit/sortable` (a11y arrow-button fallback preserved); 6 new locale strings; new `reorderWidgets` pure helper
+- **W5** dashboard tour auto-launch gated on `onboardingCompletedAt + 24 h` so the carousel and tour no longer chain immediately; "Replay the tour" CTA added to Settings → About
+- **W6** Withings OAuth `state` cookie no longer encodes `${userId}:${nonce}` — switched to a 16-byte random nonce + short-lived `WithingsOAuthState` ledger row + 03:20 cleanup cron, closing v1.4.43 audit security L-1
+- **W7** drop the in-memory `legacy_form_total` counter (per-process + useless on multi-container deploys; access-log warning still emits)
+- **W8** Coach client pre-checks `navigator.onLine` before fetching `/api/insights/chat` so an airplane-mode user gets the offline-specific `coach.network` copy immediately
+
+### Added
+
+- **`<Textarea>` primitive** (`src/components/ui/textarea.tsx`) — mirrors `<Input>`'s shape with `forwardRef` + `data-slot="textarea"`. Bakes in `text-base sm:text-sm` iOS-zoom defence, `min-h-11 sm:min-h-9` tap target floor, `autoCapitalize="sentences"`, `spellCheck={true}`, `autoComplete="off"` + password-manager-ignore data-attributes. 11 unit tests pin the contract.
+- **Per-user Coach disable toggle** — Settings → Insights "Coach ausblenden" / "Hide Coach" Switch (W3). `disableCoach` Boolean column on `User` (migration `0078_v1447_user_disable_coach`). `GET /api/auth/me/disable-coach` + `PATCH /api/auth/me/disable-coach` (60/min/user rate-limit + audit row on every state-changing call). Mount gates on `<CoachFab>`, `<CoachMount>`, `<CoachLaunchButton>`, `<SuggestedPrompts>`, hero-strip `<HealthScoreCard onAskCoach>`, `/targets` per-card CTAs. `useDisableCoach()` SSR-safe hook mirrors `useFeatureFlags()`'s defensive pattern.
+- **Dashboard drag-to-reorder** — `@dnd-kit/core` + `@dnd-kit/sortable` + `@dnd-kit/utilities` runtime deps (~29 KB gzipped). `<SortableWidgetRow>` wrapper, `closestCenter` collision, vertical-list strategy, `KeyboardSensor` + `sortableKeyboardCoordinates` for full keyboard accessibility. Drag handle is a `<GripVertical>` icon button on every row's leading edge with `cursor-grab` + `touch-none` + 6 px activation distance. Existing arrow buttons survive as the a11y fallback. `reorderWidgets()` pure helper exported for unit-testing the contract without a DOM. 6 locale strings (`dashboard.dragHandle` + `dashboard.dragHandleHint`).
+- **`<OfflineBanner>`'s sibling** — Coach send-message path now pre-checks `navigator.onLine` and short-circuits to the `coach.network` error code before the fetch attempt, so the user sees the offline-specific banner copy immediately instead of waiting on a generic network failure (W8).
+- **Withings OAuth state ledger** — new `WithingsOAuthState` model + `withings_oauth_states` table with `nonce` PK, `userId` FK (`ON DELETE CASCADE`), `expiresAt` index. Connect mints a row with `randomBytes(16).toString("base64url")` + 10 min TTL; callback verifies + DELETEs on every exit branch (single-use). Cleanup cron `withings-oauth-state-cleanup` runs daily at 03:20 Europe/Berlin via `reminder-worker.ts`. New `src/lib/withings/oauth-state.ts` module exports the shared constants + minter.
+- **"Replay the tour" CTA** in Settings → About (`<AboutSection>`). Clicking re-arms a force-launch sessionStorage marker the `<TourLauncher>` consumes on its next mount, bypassing the new 24 h auto-launch gate. Also wired into the existing "Restart onboarding tour" button in `<AccountSection>` so a same-day click after navigation still lands on the tour.
+
+### Changed
+
+- **`/api/auth/me` payload** extended with `disableCoach: boolean` (defaulted to `false` for partial-deploy rollback). `useAuth` types extended; the fetcher coerces `undefined → false` at the wire boundary.
+- **`IntegrationStatus.consecutiveFailures` column dropped** — the v1.4.45 W14 migration introduced per-kind buckets but kept the legacy integer one release as a fallback. v1.4.47 drops the column. Alert ladder + audit `attemptNumber` now read `Math.max(...Object.values(consecutiveFailuresByKind))`. Migration `0077_v1447_drop_legacy_consecutive_failures` is reversible via a `GREATEST(transient, reauth_required, persistent)` recipe documented inline.
+- **`<TourLauncher>` auto-launch gate** extended from "tour not completed" to "tour not completed AND `onboardingCompletedAt + 24 h < now()`". The mount-time clock is captured via `useState(() => Date.now())` so render stays pure. Brand-new users (`onboardingCompletedAt == null`) and same-day re-visits never see the auto-launch; the manual "Replay the tour" button still works.
+- **`messages/de.json`** + 5 sibling locales — added `dashboard.dragHandle` + `dashboard.dragHandleHint`, `settings.ai.disableCoach.{title,description,toggleAria,savedHidden,savedShown,saveError}`, `settings.about.tourReplay` + `settings.about.tourReplayHint`. Copy is tight + professional in every locale; English-fallback on `tourReplay` for es/fr/it/pl per the partial-translation status the rest of the About section already carries.
+- **Withings `state` cookie name preserved** as `withings_state`; the value shape changed from `${userId}:${nonce}` to a bare 22-char base64url nonce. A handshake mid-deploy will fail the CSRF check on the callback side (the cookie carries the old shape, the ledger has no row) and bounce the user to the connect-error page; a retry succeeds. No data loss; users in flight retry once.
+
+### Fixed
+
+- **Dashboard summary + medications/intake idempotency tests** broke on 2026-05-22 because they hard-coded `2026-05-21` while the route's projection used `new Date()`. `vi.setSystemTime` pins both ends to the same calendar day so the regression guard stays stable on every future test run (W0).
+- **Coach send-while-offline UX** — airplane-mode user no longer sees a delayed generic network error; the `<MessageThread>` now surfaces the `coach.network` copy immediately (W8). Surfaces the v1.4.45 W12 M6 errorNetwork key properly on the client side.
+- **`legacy_form_total` counter removed** — `withingsWebhookLegacyFormTotal` no longer exposed on `/api/admin/status`. Per-process in-memory counters were never accurate across the multi-container deploy; the access-log warning remains the operator signal (W7).
+
+### Operator notes
+
+- **Migration MUST run before the app image rolls**: three migrations apply via `prisma migrate deploy` in numeric order: `0076_v1447_withings_oauth_state`, `0077_v1447_drop_legacy_consecutive_failures`, `0078_v1447_user_disable_coach`. All idempotent (`IF NOT EXISTS` / `IF EXISTS`) + reversible. Running the v1.4.47 image without migration 0078 would 500 every `/api/auth/me` call because the Prisma client SELECTs `disable_coach`; run `prisma migrate deploy` first.
+- **New cron**: `withings-oauth-state-cleanup` runs daily at 03:20 Europe/Berlin via pg-boss. Wired into `reminder-worker.ts`; no extra ops setup required beyond a worker container running.
+- **No env-var change.** `pnpm check-env` still passes; the v1.4.42 env-check CI gate enforces manifest ↔ `.env.production.example` lockstep.
+- **No API contract break for iOS v0.5.4.** `disableCoach` is additively extended in `/api/auth/me` (older iOS reads coerce `undefined → false`). Withings OAuth state cookie name preserved; in-flight handshakes survive a deploy. The Coach disable toggle is opt-in; default behaviour unchanged.
+- **`pnpm test --run` green at ~5100+ passing**, `pnpm typecheck` + `pnpm lint` clean.
+
 ## [1.4.46] — 2026-05-22 — Server reconcile (PR worker cumulative-bucketing + intake auto-skip + APNS admin test)
 
 Discovery follow-up from the v1.4.45 marathon-close review surfaced three server gaps that the audit waves hadn't covered. v1.4.46 lands all three as touch-disjoint fixes.

+-- v1.4.47 W6 — Withings OAuth state nonce ledger.
+--
+-- The v1.4.43 security audit (L-1) flagged the legacy state shape
+-- `${user.id}:${random16}` as cosmetic-but-fragile: the user id is
+-- recoverable from any request log entry where the cookie isn't
+-- redacted, and from a network-traffic capture of the redirect. The
+-- cookie is `httpOnly` + `Secure` + `sameSite:lax` today so the XSS
+-- exfiltration surface is closed — but a future refactor that flips
+-- the cookie to a non-httpOnly variant would silently expose the user
+-- id. Audit recommendation was to switch the state to a fully-random
+-- 16-byte nonce backed by a short-lived `(nonce → userId)` row.
+--
+-- This table is that ledger. Each `withings/connect` mint persists one
+-- row; `withings/callback` looks it up, asserts `expiresAt > now()`,
+-- and DELETEs the row in a single transaction so a replay of the same
+-- state nonce against a fresh user session fails the CSRF check (the
+-- row is gone after first consumption). A daily cron sweeps any
+-- abandoned rows whose `expiresAt` has passed (user closed the
+-- Withings tab without completing the handshake).
+--
+-- Schema choices:
+--
+--   * `nonce` is the primary key — it's already random and
+--     22-character base64url, so a dedicated `id` column would just
+--     duplicate the key without buying anything.
+--   * `userId` carries `ON DELETE CASCADE` so removing a user cleans
+--     up their in-flight nonces atomically.
+--   * `expiresAt` is indexed for the cleanup sweep — without it the
+--     daily `DELETE … WHERE expiresAt < now()` would seq-scan the
+--     entire table once a day even though the typical row count is
+--     bounded by `users × concurrent in-flight handshakes`.
+--
+-- Idempotent guards (`IF NOT EXISTS`) match the 0067 / 0070 / 0071 /
+-- 0074 / 0075 pattern so reruns are safe.
+--
+-- Reversibility: down migration is `DROP TABLE IF EXISTS
+-- "withings_oauth_states"`. Additive-only; no existing row is
+-- touched.

+-- v1.4.47 W1 — drop the legacy `consecutive_failures` column on
+-- `integration_statuses`.
+--
+-- v1.4.43 W14 introduced `consecutive_failures_by_kind` (JSONB) as
+-- the bucketed per-FailureKind counter and kept the single-column
+-- `consecutive_failures` integer for one release as a fallback so
+-- v1.4.43 readers wouldn't break mid-deploy. v1.4.45 W10 closed the
+-- write-time gap (back-fill increment posts the bucket and the legacy
+-- column at the same N+1 value). v1.4.47 W1 drops the legacy column
+-- now that every active integration in production has written at
+-- least one new failure or success since v1.4.43 shipped (>24h ago),
+-- so every row's `consecutive_failures_by_kind` is populated and the
+-- legacy integer is redundant.
+--
+-- After this migration the alert-ladder reader uses
+-- `Math.max(...Object.values(buckets))` exclusively — the legacy
+-- column is no longer consulted. `recordSyncFailure` and friends
+-- stop writing to `consecutive_failures` entirely (the corresponding
+-- application-level cleanup in `src/lib/integrations/status.ts`
+-- lands in the same release).
+--
+-- Idempotent guard (`IF EXISTS`) matches the 0075 pattern so reruns

+-- v1.4.47 W3 — per-user Coach opt-out.
+--
+-- Privacy-leaning users want to hide the Coach surface even when the
+-- operator has enabled the global `assistant.coach` feature flag. The
+-- per-user `disable_coach` column is a hard client-side gate consulted
+-- by every Coach mount point (`<LayoutCoachFab>`, `<LayoutCoachMount>`,
+-- `<CoachLaunchButton>`, `/targets` page CTA, …) AFTER the
+-- operator-level flag check — both must agree to render the affordance.
+--
+-- Default `false` keeps the existing posture: every user who has not
+-- explicitly opted out continues to see the Coach button + drawer
+-- exactly as before. The toggle lives in Settings → Insights as a
+-- `<Switch>` labelled "Hide Coach" / "Coach ausblenden"; persisted via
+-- `PATCH /api/auth/me/disable-coach`.
+--
+-- Idempotent guard (`IF NOT EXISTS`) matches the 0067 / 0070 / 0071 /
+-- 0075 pattern so reruns are safe on prod where the migration has
+-- already been applied.
+--
+-- Reversibility: down migration is `ALTER TABLE "users" DROP COLUMN
+-- IF EXISTS "disable_coach";`. The column is `NOT NULL DEFAULT false`
+-- so the down migration is lossy (every opted-out user reverts to
+-- "Coach visible") but never crashes a roll-back. The application
+-- layer treats a missing column the same as `false` (the auth/me
+-- payload defaults the field) so a partial deploy where the schema
+-- is rolled back ahead of the app code keeps working.

+ *
+ * The toggle is reachable from Settings → Insights as a `<Switch>`
+ * labelled "Hide Coach" / "Coach ausblenden". Default `false` (Coach
+ * visible) — see migration `0076_v1447_user_disable_coach` for the
+ * column-level documentation.
+ *
+ * Idempotent. The endpoint always returns the resolved next-state
+ * shape so the client can hard-set the optimistic update without an
+ * extra round-trip. Rate-limit is intentionally generous (60/min) —
+ * the Switch is a one-tap affordance, but iOS clients may eventually
+ * batch settings round-trips after a passkey re-pair and a tight
+ * 5/min would surface as a 429 on a normal onboarding flow.

+/**
+ * v1.4.47 W5 — onboarding chain gate.
+ *
+ * `<WelcomeCarousel>` (gated on `users.onboardingCompletedAt`) and
+ * `<TourLauncher>` (gated on `users.onboardingTourCompleted`) used to
+ * both auto-launch when null. A brand-new user finished the carousel
+ * and was immediately greeted by the spotlight tour — ~90 seconds of
+ * forced onboarding before they could touch the dashboard.
+ *
+ * The fix turns the tour into "the second-visit thing": auto-launch
+ * is suppressed until `onboardingCompletedAt + 24 h`. This file pins
+ * the pure decision helper so a future refactor doesn't silently
+ * regress the gate. The "manual restart from Settings" path bypasses
+ * the gate entirely and lives in `<TourLauncher>`'s
+ * `healthlog:tour-restart` window event listener — exercised by the
+ * sections SSR smoke test (`settings/__tests__/sections.test.tsx`) +
+ * the e2e suite, not by this file.

+ * v1.4.47 W3 — Settings → AI "Hide Coach" toggle persistence contract.
+ *
+ * The card is a small client-only `<Switch>` that PATCHes
+ * `/api/auth/me/disable-coach` and invalidates `queryKeys.authMe()` so
+ * every Coach mount point in the app reacts on the next /me refetch.
+ *
+ * Test strategy: use the real `useMutation` + `QueryClient` from
+ * `@tanstack/react-query`, stub `fetch`, and drive the Switch via a
+ * `renderToStaticMarkup` pass plus a hand-invoked mutation call. The
+ * file SSR-renders inside a `<QueryClientProvider>` so the hook
+ * branches execute and the spies fire.

+ * Base textarea primitive — mirror of `<Input>` for multi-line input.

+ * v1.4.47 W2 — extracted the iOS-zoom defence + tap-target floor +
+ * autocomplete defaults that the bugreport / medications-import /
+ * side-effects / admin-feedback textareas were copy-pasting into a
+ * single primitive. Six call sites previously each maintained their
+ * own className string; any drift between them was a paper-cut waiting
+ * to happen.
+ *
+ * What it bakes in:
+ *
+ *   - `text-base sm:text-sm` — iOS Safari zooms the viewport on
+ *     focus when the font-size renders below 16 px, which yanks the
+ *     keyboard up and leaves the user lost. 16 px on mobile holds
+ *     the viewport; 14 px on `sm`+ keeps the compact desktop look.
+ *
+ *   - `min-h-11 sm:min-h-9` — WCAG 2.5.5 / Apple HIG floor of 44 px
+ *     on touch screens, shrinking to 36 px once we know we have a
+ *     pointer (covers `rows={1}` single-line uses without dropping
+ *     under the tap-target floor).
+ *
+ *   - `autoCapitalize="sentences"` — free-text fields read as prose
+ *     on iOS / Android by default. Caller can override with `"none"`
+ *     for code / JSON / IDs.
+ *
+ *   - `spellCheck` defaults to `true` — same reasoning.
+ *
+ *   - `autoComplete` defaults to `"off"` for the same reason as
+ *     `<Input>`: HealthLog is a health-data app, and we don't want
+ *     a password manager pasting the user's saved password into a
+ *     free-text textarea that we then persist server-side. Caller
+ *     can opt back in (e.g. `"on"`) per field.
+ *
+ * Composition is via `cn(…)` so callers can override anything — the
+ * primitive defaults are the strict pass, not the only pass.
