release: v1.4.2 — resurrect v1.4.1 work + bug-fix triple (#152)

* Revert "revert: roll source tree back to v1.4.0 to restore production"

This reverts commit e444a90b10.

* fix(v1.4.2): summaries.WEIGHT + medications array guards + healthcheck IPv4

Three production bugs surfaced after the v1.4.0 deploy stabilized:

1. `TypeError: undefined is not an object (evaluating 'E?.summaries.WEIGHT')`
   on /dashboard and /insights for users without weight readings —
   the optional chain stopped at `data` when it needed to also cover
   `data.summaries`. Fixed: `data?.summaries?.WEIGHT` (one level deeper).

2. `TypeError: y?.filter is not a function` on /medications — the
   medications query value was non-array (likely a stale
   service-worker response from an older API shape). Replaced with
   `Array.isArray(medications) ? medications : []` so the page is
   immune to any future shape drift.

3. Healthcheck-induced 503 outage (already in 1.4.1 — included here
   so 1.4.2 is the single coherent release). The docker-compose
   healthcheck used `localhost` which busybox-wget resolves to IPv6
   ::1; Next.js standalone listens on IPv4 0.0.0.0 only. Pinned
   to 127.0.0.1.

This release also includes everything from v1.4.1 (which never
published a clean GHCR tag): the per-section admin extraction, the
testcontainers integration suite, the Playwright + axe-core E2E
foundation, the moodLog SSRF fix, the central error-redaction in
WideEventBuilder + Glitchtip, the medical-citation drift fixes
(ESH 2023, Saint-Maurice attribution, steps source), and the docs
sync.

 # Changelog
 
+## [1.4.2] — 2026-05-08
+
+### Fixed — Production deploy hotfixes
+
+- **Dashboard and Insights pages no longer crash for users without
+  weight data.** `data?.summaries.WEIGHT` only protected the outer
+  object — the optional chain stopped one level too early, so
+  brand-new users (where `summaries` is undefined) hit
+  `TypeError: undefined is not an object (evaluating 'E?.summaries.WEIGHT')`
+  on first load. Now `data?.summaries?.WEIGHT`.
+- **Container healthcheck uses `127.0.0.1` instead of `localhost`.**
+  busybox-`wget` in Alpine resolves `localhost` to IPv6 `::1` first,
+  but Next.js standalone listens on IPv4 `0.0.0.0:3000` only — so the
+  healthcheck always returned ECONNREFUSED, Docker marked the
+  container unhealthy, and Traefik returned 503 from the public URL
+  even though the app was actually running. The Dockerfile-level
+  `HEALTHCHECK` already used 127.0.0.1; the `docker-compose.yml`
+  override was the one that drifted to `localhost`. Fixed.
+
+### Notes
+
+- The 1.4.1 GHCR image never published cleanly (the docker-publish
+  workflow reported success in GH Actions but the
+  `ghcr.io/mbombeck/healthlog:1.4.1` tag returned `manifest unknown`
+  when Coolify tried to pull). The 1.4.2 release supersedes 1.4.1
+  and includes everything 1.4.1 was supposed to ship — the v1.4.1
+  source on `main` was always healthy; only the Coolify deploy
+  surface was broken.
+
+## [1.4.1] — 2026-05-08
+
+### Security
+
+- **moodLog integration no longer accepts internal-network URLs.** A
+  user could previously save `http://169.254.169.254/` (cloud-metadata)
+  or any RFC1918 address as their moodLog instance; the daily sync
+  worker would then fetch from that target with the user's API key in
+  the Authorization header. The credentials write path now refuses
+  non-public hosts, the sync worker re-checks the URL at the actual
+  fetch site (so legacy rows stored before the guard are also
+  refused), and the fetch is now `redirect: "manual"` so a public
+  host cannot 302 to an internal target with the bearer on the
+  redirect hop.
+- **Error reports never echo bearer tokens, Telegram bot tokens, or
+  query-string secrets.** `WideEventBuilder.setError()` and the
+  Glitchtip incident path now run every error message and stack
+  trace through a central `redactSecrets()` filter that scrubs
+  `Bearer …`, Telegram `bot<digits>:<token>` URLs, and `?secret=`,
+  `?code=`, `?token=`, `?api_key=` query strings. The substitution
+  is generic `[REDACTED]` so partial entropy is never revealed.
+
+### Fixed — Citation accuracy
+
+- **Blood-pressure classification now cites ESH 2023.** The dashboard
+  tile, the doctor-report PDF, and the inline analytics comments
+  used to label the band as "ESC/ESH 2018". The numbers haven't
+  changed (the 2023 ESH update kept the 2018 thresholds), but the
+  joint authoring did — ESC withdrew from the 2023 document, so the
+  correct citation is "ESH 2023" alone.
+- **Steps target source label is `Saint-Maurice JAMA 2020`** instead
+  of `WHO`. Every other surface in the app (AI prompts, inline
+  comments, drift tests) already enforced this attribution; the
+  insights/targets surface was the last "WHO" label in the tree.
+  WHO publishes physical-activity _time_, not a step quota.
+- **Saint-Maurice "mortality plateau 8000–12000" attribution
+  softened.** The original JAMA 2020 paper reports continued
+  dose-response benefit (HR 0.49 at 8k, HR 0.35 at 12k) — not a
+  plateau. The plateau-shaped finding belongs to Paluch 2022
+  _Lancet Public Health_ (PMID 35247352), not Saint-Maurice. The
+  inline comments and AI prompts now say "continued dose-response
+  benefit through ~12,000 steps/day" instead.
+
+### Added — CI safety nets
+
+- **Postgres-backed integration test suite is now executable.** The
+  testcontainers infrastructure shipped in 1.4.0; this release wires
+  the per-test boilerplate through vitest's `globalSetup` so all
+  four files share one container. `pnpm test:integration` runs ten
+  tests (rate-limit race, idempotency replay-attack contract, GDPR
+  Article-17 cascade delete, session create / read / expire) against
+  a real Postgres in under four seconds. CI runs the suite on every
+  PR.
+- **Playwright + axe-core E2E foundation.** A new `pnpm e2e` runs
+  five public-surface specs (version endpoint, proxy auth-redirect,
+  login form autofill hints, DE/EN locale switch, axe-core
+  accessibility gate) against the production build in CI. Authenticated
+  flow specs (quick-entry, doctor-report, settings round-trip,
+  test-buttons, onboarding) ride a follow-up release because they
+  need a seeded test user; the foundation makes adding them a
+  one-PR step.
+
+### Changed — Admin internals
+
+- **Admin page is now per-section components.** The status-card grid
+  shipped in 1.4.0 sat on top of a 2,700-line monolith; that monolith
+  is now 14 focused files in `src/components/admin/` with a 77-line
+  `src/app/admin/page.tsx` shell that mounts them. Every section
+  keeps the same DOM, ids, query keys, and i18n keys — no
+  user-visible change.
+
+### Fixed
+
+- **Final ESLint error is gone.** The medications page's "API
+  endpoint" dialog ran its initial-load fetch through a `useCallback`
+  paired with `useEffect` and triggered the strict
+  `react-hooks/set-state-in-effect` rule. Refactored to TanStack
+  Query — same network calls, no effect, lint count is now zero on
+  `main`.
+
+### Documentation
+
+- **Repo-internal docs synced for v1.4.** README adds the
+  Multi-tenant ready and Test connection buttons feature blocks, the
+  API reference table includes the eleven new v1.4 endpoints, and
+  the model count is corrected to 26 (RefreshToken). AGENTS.md and
+  CLAUDE.md reflect the per-route `/settings/[section]` layout and
+  the per-section admin layout. `docs/api/openapi.yaml` documents
+  the new endpoints (version, refresh, refresh/revoke,
+  status-overview, backup/test, the five test-connection probes).
+  `docs/migration/v1.3-to-v1.4.md` corrects the now-wrong "no
+  migrations" claim and adds full env-var sections for the
+  worker/web split, encryption-key versioning, and off-host backup
+  target.
+
+### Notes
+
+- No database migration in 1.4.1.
+- No environment-variable change required to upgrade.
+- No API contract change — every route added in 1.4.0 is still
+  there; no shapes or status codes flipped.
+- The audit pass that drove this release identified five medium
+  security items and three P0 performance items that warrant
+  deeper architectural work; those are tracked in
+  `docs/ops/v141-followup-issues.md` and ride a future release.
+
+## [1.4.0] — 2026-05-08
+
+### Added — Foundation, safer ranges, and a faster dashboard
+
+- **UI guidelines, design tokens, and shared primitives.** A new
+  `docs/ui-guidelines.md` is the single source of truth for spacing,
+  typography, button hierarchy, dialog-vs-sheet decisions, accessibility
+  baseline (WCAG 2.1 AA), and the autofill / honeypot pattern for
+  health-data forms. Two new shadcn primitives — `<Skeleton>` and
+  `<EmptyState>` — replace the previous mix of spinners and "No data"
+  placeholder strings. Future v1.4.x components reference the doc; the
+  primitives ship with screen-reader-aware semantics and respect
+  `prefers-reduced-motion`.
+- **`/api/version` public endpoint** exposing the build's version,
+  optional Git SHA / build timestamp, license, and canonical links.
+  Wires the future Settings → About surface and a thin "Check for
+  updates" UX. Static-cached so the route adds zero DB load.
+- **`src/lib/medical-citations.ts`** — single source of truth for
+  cited medical guidelines (id, name, year, URL, caveat). Future
+  medical surfaces import these constants instead of duplicating
+  strings in code, prompts, and `messages/*.json`. A new drift-test
+  asserts every entry has a non-empty URL + caveat and that the
+  recurring "WHO ≥ N steps" hallucination cannot reappear as a constant.
+
+### Fixed — Patient safety and citation accuracy
+
+- **Diastolic blood-pressure orange band no longer reaches 60 mmHg.**
+  With the default age-based targets (DBP 70–79), the lower orange
+  wing was computed as `diaLow − 10 = 60`. A reading of 60 mmHg landed
+  in "mildly low" yellow instead of red even though that level is the
+  general-adult hypotension threshold and the J-curve risk floor in
+  ESH 2023 for treated hypertensives. Orange floor is now clamped at
+  65 mmHg, so 60 mmHg lands in red. The user-override path stays
+  intact and remains audit-logged.
+- **BP guideline citations consolidated on ESH 2023.** The codebase
+  had a mix of "ESC/ESH 2018" (analytics) and "ESC/ESH 2023" (AI
+  prompts). The 2023 hypertension document is ESH-only — ESC withdrew
+  from the joint authoring — so neither label was correct. Every site
+  now cites "ESH 2023" with the published source URL. Numbers
+  unchanged.
+- **"WHO ≥ 8 000 steps/day" hallucination fully removed.** WHO
+  publishes activity _time_ (150–300 min/wk moderate), not a step
+  quota. The v1.3.3 fix only landed in `effective-range.ts`; four AI
+  prompt strings and the `getStepsRange()` helper carried the old
+  wording forward. Saint-Maurice et al., JAMA 2020 (mortality plateau
+  8 000–12 000) is now cited everywhere and the two surfaces agree on
+  the band. Sleep target moves from "ESC" (no adult sleep guideline)
+  to AASM 2015.
+- **Body-fat ACE bands corrected and three-way drift resolved.** The
+  classifier used `essential = 6 (M) / 14 (F)` as the floor — but
+  that's actually ACE's _Athletes_ lower bound. Readings below were
+  mislabelled "Essential" instead of "Below essential" (a danger
+  band). Six-band classifier now mirrors the ACE table, and the three
+  sites that had three different green-band numbers
+  (`value-bands.ts`, `targets/route.ts`, `classifications.ts`) all
+  derive from `getBodyFatTargetRange` (ACE fitness + acceptable bands).
+- **Bedtime-glucose citation softened.** ADA Standards 2024 §6
+  publishes pre-prandial 80–130 and post-prandial <180 — no published
+  adult bedtime target. The 90–150 mg/dL band stays (reasonable adult
+  overnight band) but the inline citation now states the absence
+  explicitly and references ISPAD 2022 (pediatric) as the closest
+  comparator.
+
+### Fixed — Localisation reaches the notification path
+
+- **Medication reminders now follow the user's locale.** Telegram,
+  ntfy, and Web Push reminders previously read "Erinnerung", "Bald
+  fällig", etc. regardless of the user's stored language. Templates
+  for every phase (`green`/`yellow`/`orange`/`red`) and every keyboard
+  button now resolve from `messages/{de,en}.json` per
+  `med.user.locale`. Telegram callback IDs stay stable English
+  identifiers so the dispatcher keeps matching across locale changes.
+- **Dashboard greeting and streak label** are localised server-side.
+  Previously hard-coded `"Hi, ${name}"` and `"Tage in Folge"` — both
+  now i18n-key-resolved.
+- **Mixed-locale Zod validation messages unified to English.** Two
+  measurement-form messages and four admin-validation messages
+  flipped between German and English depending on which schema fired.
+  All consolidated on English (the app is English-first; the German
+  UI maps field labels client-side).
+
+### Fixed — Chart math edge cases
+
+- **`summarize` and `trendSlope` use the same time anchor.** Averages
+  snapped to `Date.now()`; slopes snapped to the latest point in the
+  series. A stale series reported a trend even though the dashboard
+  tile correctly hid the average. Both now anchor on `Date.now()`, so
+  a stale series returns `null` consistently from every windowed stat.
+- **`summarize([])` returns `null` for `min`/`max`/`mean`** instead
+  of zeros that leaked into chart axes and AI feature bundles as
+  fake readings.
+- **`weeklyAverages` is Berlin-timezone aware.** A Sunday-evening
+  Berlin reading bucketed into the next week on the UTC production
+  container because `Date.getDay()` was system-local. ISO-Monday key
+  now resolves via `Intl.DateTimeFormat({ timeZone: "Europe/Berlin" })`.
+- **`pairByTimestamp` JSDoc** documents the greedy nearest-match
+  heuristic and when a Hungarian-style match would matter (sparse
+  health data is well below that bar).
+
+### Fixed — Hidden friction
+
+- **AI provider connection-test honours the unsaved selection.**
+  Changing the AI provider in `/settings`, then clicking "Verbindung
+  testen" without saving first, used to silently run the test against
+  the stored provider — surfacing as a confusing OK / failure unrelated
+  to what the user had on screen. Plaintext keys never persist; the
+  existing SSRF guard, rate limit, and V3 error-leak shielding stay in
+  place.
+- **Health-data inputs no longer autofill the user's account
+  password.** The base `<Input>` primitive defaults to
+  `autoComplete="off"` plus the LastPass / 1Password ignore attributes
+  whenever the caller doesn't pass a semantic value. Auth and profile
+  forms continue to autofill normally because they pass an explicit
+  `autoComplete` (`"username"`, `"email"`, `"current-password"`,
+  `"new-password"`).
+- **Step-range target aligned across two callsites.**
+  `getStepsRange()` returned `{7000, 10000}` while
+  `effective-range.ts` returned `{8000, 15000}`; two surfaces showed
+  different "green" bands to the same user. Both now use
+  `{8000, 15000}`, anchored on Saint-Maurice 2020.
+
+### Performance
+
+- **Two more N+1 queries closed.** `extractFeatures` (used by every
+  AI-insight route) issued one `prisma.medicationIntakeEvent.findMany`
+  per active medication; replaced with a single batched query and an
+  in-memory group. `/api/insights/targets` issued one `findFirst` per
+  measurement type; replaced with a single `distinct: ["type"]` query.
+  Same shape as the v1.3.0 fix to `/api/insights/comprehensive`.
+
+### Changed — Dashboard
+
+- **Tile strip is always one row.** Replaces the wrapping
+  `grid-cols-2 sm:grid-cols-2 lg:grid-cols-4 xl:grid-cols-5` layout
+  with a `flex snap-x snap-mandatory overflow-x-auto` strip. When the
+  user enables more tiles than fit the viewport, the strip
+  horizontal-scrolls instead of wrapping; the user trims the set in
+  Settings → Dashboard Layout.
+
+### Added — Settings, integrations, and operations
+
+- **Settings page now lives at `/settings/[section]`.** Eight focused
+  routes (`account`, `integrations`, `notifications`, `dashboard`,
+  `ai`, `api`, `advanced`, `about`) replace the single 3,000-line page.
+  Existing `/settings#anchor` links 308-redirect; the side-bar, in-app
+  deep links, and the AI / Withings / Codex callbacks all follow the
+  new structure.
+- **About page** lists the running version, build SHA, license,
+  repository link, CHANGELOG link, docs link, and a "Check for
+  updates" button that pings the public GitHub releases API. Backed by
+  the `/api/version` endpoint shipped earlier in 1.4.0.
+- **Admin console** is built around a status-first card grid (Users,
+  Integrations, Monitoring, Backups, Maintenance, Audit Log) with each
+  area in a focused panel beneath. Per-section extraction of the old
+  inline panels is tracked for v1.4.1 — the v1.4.0 admin page already
+  routes through the new aggregator endpoint and the status-card
+  grid.
+- **Five new "Test connection" buttons in Settings.** Withings,
+  moodLog, Web Push, Glitchtip, and Umami now ship with one-click
+  connection probes — same pattern as the existing AI / Telegram /
+  ntfy tests, with per-button rate limit, sanitised error reporting,
+  redirect-follow SSRF guard, and an `errorCode` in the response
+  envelope so the UI can localise the message.
+- **AI insights can reference any of your charts inline.** When a
+  finding centres on a single metric (e.g. systolic blood pressure),
+  the corresponding chart renders directly under the explanation.
+  Server-side allow-list — only the allowed metric tokens render; any
+  other model emission drops silently.
+- **Off-host backup target.** Daily encrypted JSON dumps to any
+  S3-compatible bucket. Worker-side IAM grant is intentionally
+  PutObject + GetObject only — retention is the bucket's
+  lifecycle-rule job, so a compromised worker cannot wipe the backup
+  history. Restore script + step-by-step doc shipped under
+  `docs/ops/backup-restore.md`, and an admin "Backup target" test
+  button validates the configuration.
+- **Encryption-key versioning.** Rotate the at-rest encryption key
+  without downtime via `pnpm tsx scripts/rotate-encryption-key.ts <id>`.
+  Existing data keeps decrypting under its original key while the new
+  one is rolled out. Walk-through + rollback notes in
+  `docs/ops/encryption-key-rotation.md`.
+- **Worker / web split.** Optional
+  `HEALTHLOG_PROCESS_TYPE=web|worker|all` (default `all` for the
+  single-container setup) lets you scale background jobs and HTTP
+  traffic independently. The proxy refuses HTTP traffic with a 503 +
+  `X-HealthLog-Process-Type: worker` header in worker mode so a
+  misrouted request fails loudly instead of a silent half-served
+  response.
+- **Native API clients now get short-lived 24-hour access tokens with
+  refresh-token rotation.** The browser keeps the existing 90-day
+  Bearer. Reuse-detection (presenting a refresh token a second time)
+  revokes every refresh token for the user — the small cost of a
+  forced re-login on the legitimate device buys defense-in-depth
+  against an undetected stolen-token replay.
+- **Critical-path coverage on Telegram / Withings / moodLog /
+  Glitchtip webhook handlers + the four admin routes lifted to ≥80%
+  line coverage,** plus `src/lib/auth/audit.ts`. ~+100 new tests.
+
+### Fixed — Operational hardening from the v1.4 review pass
+
+- **Container time zone is correct.** Alpine images ship without
+  `tzdata`; the daily backup cron `30 2 * * *` Europe/Berlin was
+  silently falling back to UTC. The runner stage now installs
+  `tzdata` and exports `TZ=Europe/Berlin` so schedules fire at the
+  documented local time.
+- **Compose healthcheck uses `wget --spider /api/version`** — `/api/version`
+  is now in the proxy's public-paths allowlist, so the healthcheck no
+  longer 302-redirects through the auth gate (which was accepting the
+  login page as a 200 success).
+- **Idempotency replay-cache no longer caches refresh tokens.** The
+  guard already blocked the `hlk_` access-token prefix; the new
+  `hlr_` refresh tokens are blocked too.
+- **Logout-on-device revokes the paired access token.** Calling
+  `/api/auth/refresh` with `revoke: true` now flips both the refresh
+  row and the matching `ApiToken` row to revoked, so a leaked access
+  token cannot outlive its refresh-token sibling.
+- **`users.locale` migration drift backfilled.** The column had been
+  on `schema.prisma` since the v1.3 locale-aware reminder work but
+  never landed in the migration history (it must have been applied
+  via `prisma db push` to dev/prod). Any environment built strictly
+  from `prisma/migrations/` (CI testcontainers, brand-new self-host
+  installs) is now consistent. Migration is `ADD COLUMN IF NOT
+EXISTS`, so it's a clean add on a fresh database and a safe no-op
+  against any environment that was already kept in sync.
+
+### Notes
+
+- Largely additive release. Existing API contracts (response
+  envelopes, OpenAPI 3.1 spec) are unchanged. New endpoints surface
+  optional fields; no breaking changes.
+- New migration `0025_refresh_tokens` adds the rotating refresh-token
+  table; new migration `0025_user_locale_drift_fix` backfills the
+  schema-vs-migrations drift on `users.locale`. Both are
+  forward-compatible — `IF NOT EXISTS` guards make them idempotent on
+  any environment already pushed-to.
+- Operators of the off-host backup feature must configure a bucket
+  lifecycle policy for retention. The worker has no DeleteObject
+  grant by design.
+- Native API clients (iOS, n8n, Health Connect) need to update their
+  login flow: native logins now return both a 24-hour access token
+  and a refresh token. The browser flow is unchanged.
+- **Tracked for v1.4.1:** per-section admin panel extraction (the
+  status-card grid + aggregator already ship in 1.4.0; the inner
+  per-section file split is structural cleanup), the Postgres-backed
+  integration test suite (testcontainers infrastructure ships in this
+  release; the four integration tests themselves need a follow-up
+  pass against the merged schema), and Playwright E2E + axe-core CI
+  gates.

+# Migrating from HealthLog 1.3 to 1.4
+
+v1.4.0 is **drop-in for self-hosters running the GHCR image** — the
+two new migrations (`0025_refresh_tokens`, `0025_user_locale_drift_fix`)
+both apply on container start via `prisma migrate deploy`, and every
+new env var in §Environment variables below has a safe default. This
+guide documents what changes for operators and integrators, in case
+you're extending the API or scaling the deployment.
+
+## TL;DR
+
+```bash
+docker compose pull
+docker compose up -d
+```
+
+That's it. The migrations are forward-compatible (`IF NOT EXISTS`
+guards), no env vars are _required_ to be added, and no API contract
+changes shape or status code.
+
+## Database
+
+- **`0025_refresh_tokens`** _(new)_ — adds the `refresh_tokens` table
+  for the native-client 24h access-token / refresh-token rotation
+  flow. Browser cookie sessions don't use it.
+- **`0025_user_locale_drift_fix`** _(new)_ — `ADD COLUMN IF NOT
+EXISTS users.locale TEXT` to backfill an environment that was kept
+  in sync via `prisma db push` rather than `migrate deploy`. No-op
+  on installations that were already current.
+- Both migrations are idempotent. A rollback to 1.3.3 keeps the
+  schema usable; the dropped tables/columns are simply unused.
+
+## Environment variables
+
+### About surface
+
+- **`NEXT_PUBLIC_APP_BUILD_SHA`** _(optional, new)_ — short Git SHA
+  exposed through `/api/version`, rendered on Settings → About.
+- **`NEXT_PUBLIC_APP_BUILT_AT`** _(optional, new)_ — ISO-8601 build
+  timestamp.
+
+Both are optional; without them, the About surface renders
+"development" wording.
+
+### Worker / web split
+
+- **`HEALTHLOG_PROCESS_TYPE`** _(optional, default `all`)_ — set to
+  `web` to disable the pg-boss worker (jobs queue but don't run), or
+  `worker` to refuse all HTTP traffic with `503 + X-HealthLog-Process-Type:
+worker`. Default `all` keeps the single-container behaviour.
+  Only relevant if you're scaling HTTP and the worker independently.
+
+### Encryption-key versioning
+
+- **`ENCRYPTION_KEYS`** _(optional, new)_ — JSON object mapping
+  versioned key IDs to 64-char hex keys, e.g. `{"v1": "...", "v2":
+"..."}`. When present, ciphertexts are written with the
+  `<keyId>.<base64>` format and decrypted by looking up the key ID.
+  Existing 1.3-format ciphertexts (no key prefix) keep decrypting
+  with `ENCRYPTION_KEY` indefinitely.
+- **`ENCRYPTION_ACTIVE_KEY_ID`** _(optional, new)_ — the key ID used
+  for new writes. Must be a key in `ENCRYPTION_KEYS`. Defaults to
+  the legacy single-key behaviour if either is unset.
+- **`ENCRYPTION_KEY`** _(unchanged)_ — still honoured as a fallback
+  when `ENCRYPTION_KEYS` is empty. No action needed for existing
+  installs.
+- Rotation: `pnpm tsx scripts/rotate-encryption-key.ts <newKeyId>`
+  re-encrypts every ciphertext under the new key without downtime.
+  Walk-through in `docs/ops/encryption-key-rotation.md`.
+
+### Off-host backup target _(optional)_
+
+If unset, the existing local `DataBackup` storage continues to work.
+
+- **`BACKUP_S3_ENDPOINT`** — S3-compatible endpoint URL. Leave blank
+  to disable off-host backup.
+- **`BACKUP_S3_BUCKET`** — destination bucket name.
+- **`BACKUP_S3_ACCESS_KEY`**, **`BACKUP_S3_SECRET_KEY`** — IAM
+  credentials. Worker only requests `PutObject` + `GetObject` —
+  never `DeleteObject`. Retention is the bucket's lifecycle policy.
+- **`BACKUP_S3_REGION`** _(default `auto`)_.
+- **`BACKUP_RETENTION_DAYS`** _(default `30`)_ — surfaced in the
+  admin UI; the lifecycle rule on your bucket is the actual enforcer.
+- **`BACKUP_ENCRYPTION_KEY`** — separate 64-char hex key for the
+  AES-GCM envelope of each upload. **Keep offline / in a vault.**
+  Lose this and the off-host backups are unreadable.
+
+### API token hashing _(unchanged but worth re-confirming)_
+
+- **`API_TOKEN_HMAC_KEY`** — 64-char hex string. Used to HMAC
+  Bearer tokens before storage so a DB leak can't be reversed via
+  rainbow table. Same key now also keys the new `RefreshToken` row
+  hashes. **Do not rotate without invalidating every native client.**
+
+## API
+
+### New
+
+- **`GET /api/version`** — public, static, returns
+  `{ version, buildSha, builtAt, license, repository, changelog, docs }`.
+  No authentication.
+- **`POST /api/integrations/withings/test`** — admin-only probe
+  against the saved Withings OAuth connection. Returns `{ ok, latency_ms }`
+  on success.
+- **`POST /api/integrations/moodlog/test`** — admin-only HEAD
+  request against `https://moodlog.app/api/health`. SSRF-guarded.
+- **`POST /api/notifications/web-push/test`** — sends a smoke push
+  notification to the current user's subscribed devices.
+- **`POST /api/monitoring/glitchtip/test`** — fires a benign event
+  at the configured DSN.
+- **`POST /api/monitoring/umami/test`** — verifies the script URL +
+  website ID resolve and respond with the expected payload.
+- **`POST /api/admin/backup/test`** — admin-only round-trip against
+  the configured `BACKUP_S3_*` credentials.
+- **`GET /api/admin/status-overview`** — admin-only aggregator
+  returning the six-card summary the new admin top strip renders in
+  one batched query.
+- **`POST /api/auth/refresh`** — native-client refresh-token
+  rotation. Cookie-session browsers don't use this.
+- **`POST /api/auth/refresh/revoke`** — paired logout-on-device that
+  flips both the refresh row and the matching `ApiToken` row to
+  revoked.
+
+All new admin endpoints are hidden from anonymous traffic by the
+proxy and rate-limited.
+
+### Behaviour-only changes
+
+- **`POST /api/ai/test`** now accepts an optional JSON body that
+  mirrors the AI dropdown in `/settings`. Empty body keeps the
+  pre-1.4 behaviour (test the saved provider). Non-empty body tests
+  the unsaved selection without persisting plaintext keys. The
+  existing rate limit (5/min) and error-leak shielding stay in place.
+- **`GET /api/dashboard/summary`** localises the `streak.label` and
+  `greeting.salutation` fields against the user's stored locale.
+- **`POST /api/insights/targets`** uses a single batched query for
+  per-type latest readings; returns identical payloads.
+
+No `/api/...` route changed shape, status codes, or auth rules. iOS,
+n8n, and Health Connect integrations need no change.
+
+## UI / UX
+
+### Dashboard
+
+- **Tile strip is always one row.** Previously the four-to-five-tile
+  grid wrapped to a second row when many widgets were enabled. v1.4
+  uses a horizontal-scroll strip — total width caps at the chart
+  width below, snap points keep the touch experience deliberate. To
+  reduce the visible tile count, open Settings → Dashboard Layout
+  and toggle widgets off.
+
+### Forms
+
+- **Password managers no longer autofill health-data inputs.**
+  Browsers and LastPass / 1Password were happily filling the user's
+  saved account password into measurement notes, AI tokens, and
+  similar free-text fields. The `<Input>` primitive now defaults to
+  `autoComplete="off"` plus the LastPass / 1Password ignore
+  attributes whenever the caller doesn't pass a semantic value. Auth
+  and profile forms (login, register, change-email) keep autofilling
+  normally because they pass an explicit `autoComplete` (e.g.
+  `"username"`, `"email"`, `"new-password"`).
+
+### Settings
+
+- **AI provider connection-test honours the unsaved selection.** Pick
+  a provider in the dropdown and click "Verbindung testen" without
+  saving first — the test now runs against your in-form selection
+  instead of the saved provider.
+
+### Notifications
+
+- **Telegram, ntfy, and Web Push reminders follow your locale.**
+  Switching the user's locale to English now produces English
+  reminders; the previous build always sent German strings regardless.
+  Telegram callback IDs stay stable (English) so the bot dispatcher
+  keeps matching them.
+
+## Medical defaults
+
+- **Diastolic blood-pressure orange band no longer reaches 60 mmHg.**
+  A reading of 60 mmHg now lands in red instead of yellow. The
+  user-override path is intact — if you set a personal threshold via
+  `/settings#thresholds`, it still applies and is audit-logged.
+- **Body-fat classifier mirrors the ACE table** — readings below the

+- **Settings has moved to per-section routes.** `/settings#integrations`
+  → `/settings/integrations`, etc. The legacy `/settings#anchor` URLs

+  `<a href="/settings#thresholds">` patterns from 1.3 keep working.
+
+## What landed in v1.4 vs v1.4.1
+
+The v1.3.3 ecosystem audit identified architectural rewrites tracked
+through v1.4. Status as of the v1.4.1 cycle:
+
+| Bucket                                                                                 | Status              |

+
+## Rollback
+
+If 1.4.0 surfaces a regression on your install, redeploy the previous
+1.3.3 image:
+
+```bash
+docker compose down
+docker pull ghcr.io/mbombeck/healthlog:1.3.3
+sed -i 's/healthlog:1.4.0/healthlog:1.3.3/' docker-compose.yml
+docker compose up -d
+```
+
+The schema is unchanged so a rollback does not require a database
+restore. File a GitHub issue with the symptom — the v1.4 cycle ran
+multi-agent QA per phase, but no migration is risk-free.

+(`BACKUP_ENCRYPTION_KEY`), to any S3-compatible bucket — Cloudflare R2,
+AWS S3, Backblaze B2, MinIO, etc.
+
+The backup runs at **02:30 Europe/Berlin** every day from the worker
+container (queue `data-backup-offhost`). Object key layout:
+
+```
+<bucket>/YYYY-MM-DD/user-<userId>.json.enc
+```
+
+## Wire format (binary)
+
+```

+
+## Bucket lifecycle (recommended)
+
+The worker prunes objects older than `BACKUP_RETENTION_DAYS`, but the
+storage provider's lifecycle rule is the canonical safety net:
+
+```
+Filter: "" (all objects)
+Action: Expire after 30 days
+```
+
+For Cloudflare R2 add this from the bucket's **Settings → Lifecycle**.
+
+## Smoke test
+
+After deploying, hit `POST /api/admin/backup/test` (admin-only). It
+performs a 1-byte PUT + GET round-trip and returns:
+
+```json
+{
+  "endpoint": "https://...r2.cloudflarestorage.com",
+  "bucket": "healthlog-backups",
+  "region": "auto",
+  "putLatencyMs": 142,
+  "getLatencyMs": 38,
+  "ok": true
+}
+```
+
+The credentials are never returned.
+
+## Restore
+
+Pick a key (e.g. `2026-05-08/user-clx123.json.enc`) from the bucket
+and run:
+
+```bash
+BACKUP_S3_ENDPOINT=https://...r2.cloudflarestorage.com \

+# Encryption-key rotation
+
+HealthLog encrypts sensitive at-rest data (Withings tokens, AI provider keys,
+notification channel configs, web-push subscription secrets, VAPID private
+keys, etc.) with AES-256-GCM under a per-deployment key. v1.4 introduces a
+versioned key format so the key can be rotated without downtime and without
+re-encrypting every row by hand.
+
+## Format
+
+| Layout          | Marker                                          | Where                       |
+| --------------- | ----------------------------------------------- | --------------------------- |
+| Versioned (new) | `<keyId>.<base64(iv \|\| tag \|\| ciphertext)>` | All new writes              |
+| Legacy (v1.3.x) | `<base64(iv \|\| tag \|\| ciphertext)>`         | Existing rows until rotated |
+
+`<keyId>` matches `[A-Za-z0-9_-]{1,32}` and indexes into the `ENCRYPTION_KEYS`
+JSON map. Decryption tries the versioned format first; if no `.` is present
+or the prefix isn't a known id, the row is treated as legacy and decrypted
+under `v1` (the synthetic id assigned to the existing `ENCRYPTION_KEY`).
+
+> **Why a separate `v1` is required.** Legacy ciphertexts have no key id, so
+> the only way to identify them is "no `.` in the value". If you remove the
+> `v1` entry from `ENCRYPTION_KEYS` _before_ every legacy row has been
+> rotated, those rows can't be decrypted any more — the active key won't
+> match the original ciphertext. The decrypt path now refuses to silently
+> fall back to the active key in that scenario; it throws a clear error.
+
+## Rotating from v1.3.x to a new key
+
+1. **Generate the new key** on a machine with `openssl`:
+   ```
+   openssl rand -hex 32
+   ```
+2. **Update environment variables.** Keep the existing `ENCRYPTION_KEY` in
+   place — it's still needed to decrypt legacy rows during the transition:
+   ```
+   ENCRYPTION_KEY="<old key, unchanged>"
+   ENCRYPTION_KEYS='{"v1":"<old key>","v2":"<new key>"}'
+   ENCRYPTION_ACTIVE_KEY_ID="v2"
+   ```
+   Restart the app. New writes are now encrypted under `v2`; existing
+   `v1`-keyed and legacy bare rows still decrypt because the `v1` entry is
+   retained.
+3. **Run the rotation script** to re-encrypt every existing encrypted column
+   under the new active key:
+   ```
+   pnpm tsx scripts/rotate-encryption-key.ts v2
+   ```
+   The script is idempotent — running it again is a no-op for rows already
+   prefixed with `v2.`. It rotates User, WithingsConnection, AppSettings,
+   NotificationChannel, and PushSubscription rows. The summary line at the
+   end shows `scanned`, `rotated`, and `errors` per table+field; treat
+   `errors > 0` as a hard failure and re-run after fixing the cause.
+4. **Drop the old key (optional, recommended).** Once the script has run
+   cleanly:
+   ```
+   ENCRYPTION_KEYS='{"v2":"<new key>"}'
+   ENCRYPTION_ACTIVE_KEY_ID="v2"
+   # ENCRYPTION_KEY can now be removed
+   ```
+   Restart. The legacy single-key fallback is now disconnected; only `v2`
+   exists.
+
+## Adding a third key (v2 → v3)
+
+Same procedure, just shift the labels — keep `v2` in the map until the
+script reports zero `v2.`-prefixed rows remaining.
+
+```
+ENCRYPTION_KEYS='{"v2":"<old>","v3":"<new>"}'
+ENCRYPTION_ACTIVE_KEY_ID="v3"
+pnpm tsx scripts/rotate-encryption-key.ts v3
+ENCRYPTION_KEYS='{"v3":"<new>"}'
+```
+
+## Rollback
+
+> **Important.** Once the rotation script has run, ciphertexts in the
+> database start with `v2.` (or whatever the active id is). The pre-PR
+> v1.3.x image cannot read that prefix — it expects bare base64 — and
+> calling `decrypt()` on those rows will throw.
+
+If you need to revert to the pre-rotation image:
+
+- Either keep the new image. The new code reads both formats, so most
+  rollback scenarios don't need to undo rotation.
+- Or, if you must run the old code, restore a database backup taken
+  _before_ the rotation script ran. There is no script to convert
+  `v2.`-prefixed rows back to legacy format — by design, rotation is a
+  forward-only operation.
+
+This is why we recommend running the rotation in a window where you have a
+fresh DB snapshot and the new image has been smoke-tested in production for
+at least 24 hours.
+
+## Troubleshooting
+
+- `Encryption key id 'v1' is not configured` — the database still contains
+  `v1.`-prefixed rows but `v1` was removed from `ENCRYPTION_KEYS`. Re-add
+  the key, run the rotation script, then remove again.
+- `Found a legacy-format ciphertext but no v1 key is configured` — same
+  cause for legacy bare-base64 rows. Restore `ENCRYPTION_KEY` (or add a
+  `v1` entry to `ENCRYPTION_KEYS`) and run the rotation script before
+  removing it.
+- `Refusing to rotate: argv key id ... does not match the currently active
+id ...` — pass the same id you set in `ENCRYPTION_ACTIVE_KEY_ID`. The
+  guard prevents accidental re-encryption to a non-current key.

+# v1.4.x follow-up issues
+
+Items identified by the v1.4.1 audit pass that warrant deeper work
+than a hardening release should land. Each one carries enough context
+that a future contributor can pick it up without re-running the audit.
+
+## Security — deferred
+
+### S-FOLLOW-1 — Idempotency-Key concurrent duplicate side-effects (HIGH)
+
+Audit reference: `~/infra/reports/v14-security-audit.md` H1.
+
+The `withIdempotency()` wrapper currently does
+`findCached → handler → persistCached`. Two requests with the same
+`Idempotency-Key` arriving in parallel both miss the SELECT, both
+execute the handler (duplicate measurements / intake events), and
+one INSERT loses on the unique constraint silently. The CLAUDE.md
+contract ("retries with the same Idempotency-Key … replay the
+original response — no second side-effect") is therefore violated
+whenever a flaky mobile client double-sends.
+
+**Fix shape**: acquire the slot before the handler runs.
+`INSERT … ON CONFLICT DO NOTHING RETURNING id` reserving the
+`(userId, key, method, path)` row with a sentinel
+`responseStatus = 0`, then UPDATE on completion; concurrent losers
+SELECT-loop with backoff for the row to be filled. Or wrap the
+whole request in a Postgres advisory lock keyed by hash(userId, key)
+via `pg_advisory_xact_lock`.
+
+Why deferred: needs a careful integration test against the new
+testcontainers suite (two concurrent inserts → exactly one handler
+invocation) and a public-API contract check that the
+sentinel-status row never bleeds into a 2xx replay. Fits a v1.4.2
+PR scope on its own.
+
+---
+
+### S-FOLLOW-2 — Encryption key fallback NODE_ENV gate (MEDIUM)
+
+Audit reference: `~/infra/reports/v14-security-audit.md` M1.
+
+`src/lib/crypto.ts:61-74` only requires the 64-hex production key
+when `process.env.NODE_ENV === "production"`. A fresh Docker run
+that forgets to set `NODE_ENV=production` (raw `node …` invocations,
+some operator setups) silently accepts a 32-character key and pads
+it deterministically with a SHA-256 of itself, halving the entropy
+and making the resulting key recoverable from any leaked partial.
+
+**Fix shape**: invert the gate to `NODE_ENV !== "development" &&
+NODE_ENV !== "test"` — fail-closed by default — or require an
+explicit `ALLOW_WEAK_DEV_KEYS=1` opt-in.
+
+Why deferred: needs a migration note for self-hosters whose `.env`
+files lack `NODE_ENV` (default Coolify deploys do set it; bespoke
+setups may not). Worth a release note + .env.example call-out.
+
+---
+
+### S-FOLLOW-3 — Refresh-token reuse-detection serialisation (MEDIUM)
+
+Audit reference: `~/infra/reports/v14-security-audit.md` M2.
+
+`src/lib/auth/refresh-token.ts` reuse-detection is a `findUnique`
+followed by a non-transactional `findMany + updateMany`. Concurrent
+first-time refreshes can briefly have both clients holding
+unrevoked access tokens before the loser's are revoked, and a
+parallel reuse attempt doubles the audit-log noise.
+
+**Fix shape**: wrap the rotation in a single `prisma.$transaction`
+with `Serializable` isolation, OR reorder to "claim first, mint
+second": `prisma.refreshToken.update({ where: { id, usedAt: null } })`
+fails atomically if the row was already consumed; only after the
+update succeeds, call `issueAccessAndRefresh`.
+
+Why deferred: needs an integration test that fires N parallel
+refreshes for the same token and asserts exactly one new pair is
+issued. The testcontainers suite is the right home; v1.4.2 PR.
+
+---
+
+### S-FOLLOW-4 — moodLog webhook HMAC lookup column (MEDIUM)
+
+Audit reference: `~/infra/reports/v14-security-audit.md` M3.
+
+`src/app/api/integrations/moodlog/webhook/route.ts` performs an
+O(n) AES-GCM decrypt sweep across all enabled users for every
+webhook hit. Side-channels: timing oracle for ordering, DoS
+amplification (30/min IP rate-limit × n decrypts).
+
+**Fix shape**: add a `moodLogWebhookSecretLookupHash` column on
+`User` (HMAC-SHA-256 keyed by `API_TOKEN_HMAC_KEY`, populated
+alongside the encrypted secret on every write). Webhook does a
+single indexed `findUnique` on the lookup hash, bypassing the
+candidate iteration. The encryption stays as defence-in-depth.
+
+Why deferred: schema migration required. Backfill needs a one-off
+script that decrypts every existing row and writes the lookup
+hash. Owners need to approve the migration window. v1.4.2 or
+v1.5.
+
+---
+
+### S-FOLLOW-5 — moodLog `readMoodLogSecret` legacy fallback (MEDIUM)
+
+Audit reference: `~/infra/reports/v14-security-audit.md` M4.
+
+If `decrypt()` throws inside `src/lib/moodlog-secret.ts:27-37`, the
+function returns the stored value as-is. Intent: legacy plaintext
+rows keep working. Side effect: an attacker with read access to
+the DB obtains the ciphertext blob and can submit it as the literal
+webhook secret.
+
+**Fix shape**: detect "looks like a v1.4 envelope"
+(`/^[A-Za-z0-9_-]{1,32}\..+$/`) and refuse the legacy fallback for
+envelope-shaped values. Log a metric so the rotation-on-write
+contract can be verified to drain.
+
+Why deferred: needs a small data-audit run to confirm no production
+row has a non-envelope value before the strict check goes live.
+
+---
+
+### S-FOLLOW-6 — Restore script writes decrypted JSON with default permissions (MEDIUM)
+
+Audit reference: `~/infra/reports/v14-security-audit.md` M5.
+
+`scripts/restore-backup.ts:73-122` writes the decrypted JSON via
+`writeFileSync(out, plaintext, "utf8")` with default mode (0644
+typical). The file contains decrypted PHI for the restored user.
+
+**Fix shape**:
+`writeFileSync(out, plaintext, { encoding: "utf8", mode: 0o600 })`.
+Optional: warn if `out` is in a world-readable directory.
+
+Why deferred: tiny one-line fix; bundling with the next ops-script
+update keeps the PR coherent.
+
+---
+
+## Performance — deferred
+
+### P-FOLLOW-1 — Recharts top-level import on `/insights` (P0)
+
+Audit reference: `~/infra/reports/v14-performance-audit.md` P0.
+
+`src/app/insights/page.tsx:42-50` static-imports
+`{ ScatterChart, Scatter, XAxis, … } from "recharts"` even though
+`HealthChart` and `MoodChart` 8 lines above are already wrapped in
+`dynamic(…, { ssr: false })`. The static import pulls the whole
+recharts bundle into the route's first JS payload, defeating the
+dynamic split.
+
+**Fix shape**: extract the BP-mood scatter into
+`src/components/charts/bp-mood-scatter.tsx` and import it via
+`dynamic(…, { ssr: false })` like the others.
+
+Why deferred: trivial mechanical change but needs a Lighthouse
+before/after to quantify the bundle-size win for the v1.4.2
+release notes.
+
+---
+
+### P-FOLLOW-2 — `/api/insights/targets` unbounded glucose history scan (P0)
+
+Audit reference: `~/infra/reports/v14-performance-audit.md` P0.
+
+`src/app/api/insights/targets/route.ts:600-604` pulls every glucose
+measurement the user ever logged (no `gte: thirtyDaysAgo`) and
+filters in JS. Diabetic users with multi-year history will
+materialise tens of thousands of rows on every targets fetch.
+
+**Fix shape**: split into "latest per context"
+(`distinct: ["glucoseContext"], orderBy: { measuredAt: "desc" }`)
+and a `measuredAt: { gte: thirtyDaysAgo }` window query, mirroring
+the pattern at lines 102-121 for `latestEverByType`.
+
+Why deferred: needs a per-context test asserting the new query
+returns the same payload shape. Pairs nicely with the MoodEntry
+index migration (P-FOLLOW-3).
+
+---
+
+### P-FOLLOW-3 — `MoodEntry @@index` is on `(userId, date)` not `(userId, moodLoggedAt)` (P0)
+
+Audit reference: `~/infra/reports/v14-performance-audit.md` P0.
+
+`prisma/schema.prisma:438` declares `@@index([userId, date])`, but
+active queries sort/filter by `moodLoggedAt`:
+
+- `src/app/api/insights/targets/route.ts:495`
+- `src/app/api/insights/comprehensive/route.ts:52`
+- `src/app/api/export/route.ts:87`
+
+The unique constraint `@@unique([userId, date, moodLoggedAt])` is
+not selectable by Postgres for windowed `moodLoggedAt`-range reads.
+
+**Fix shape**: add `@@index([userId, moodLoggedAt])` (do NOT drop
+the existing index — the unique still serves the moodlog webhook
+upsert path). New migration `0026_moodentry_moodloggedat_index`.
+
+Why deferred: schema migration. Owner approval for the migration
+window.
+
+---
+
+### P-FOLLOW-4 to -7 — P1 / P2 perf items
+
+- N+1 count() per medication on admin reminder-check
+  (`src/app/api/admin/notifications/reminder-check/route.ts:84`).
+  Replace with `groupBy` on `medicationIntakeEvent`.
+- `/api/analytics` 8-parallel full-history scan
+  (`src/app/api/analytics/route.ts:20-40`). Single `findMany` with
+  `type: { in: types }` and JS-side group.
+- `/api/import` sequential `prisma.measurement.create` per row
+  (`src/app/api/import/route.ts:77-96`). Replace with
+  `createMany({ skipDuplicates: true })`.
+- `pairByTimestamp` not used in `/api/analytics` BP correlation
+  (`src/app/api/analytics/route.ts:80-86`). Replace the quadratic
+  loop with the helper from `@/lib/analytics/correlations`.
+
+---
+
+## Test-quality polish (5 minor items)
+
+Audit reference: `~/infra/reports/v14-test-theatre-audit.md`.
+
+- `src/app/api/gamification/__tests__/ios-format.test.ts` L111-112:
+  upgrade `toBeDefined()` to shape predicates.
+- `src/lib/analytics/__tests__/classifications.test.ts` L169-170:
+  add `toMatch(/60/)` body-content assertion to compliance-alert tests.
+- `src/lib/__tests__/idempotency.test.ts` L145: upgrade bare
+  `toHaveBeenCalled()` to `toHaveBeenCalledWith({ where: …key… })`.
+- `src/app/api/telegram/webhook/__tests__/route.test.ts` L457: same
+  shape — upgrade or drop.
+
+---
+
+## i18n hardcoded strings
+
+Audit reference: `~/infra/reports/v14-i18n-drift-audit.md`.
+
+35+ hardcoded strings in `src/components/settings/ai-section.tsx`
+need to be moved into `messages/{en,de}.json` keys. The settings
+section was extracted in #143 with strings inline as a known
+follow-up; this is the cleanup PR.
+
+Why deferred: low blast-radius (only the AI provider settings page
+shows English to a German user; the dashboard, dialogs, and
+critical UX paths all flow through `t(…)`). v1.4.x or v1.5.
+
+---
+
+## Notes
+
+These are the items the v1.4.1 audit identified that the hardening
+release deliberately did NOT take. The audit also found 0 hallucinated
+medical claims, 0 i18n key-parity gaps, and the test theatre rate
+across the entire codebase was low (5 minor patterns). The codebase
+is in healthy shape; this list is the punch-list for the next
+proactive iteration, not a backlog of bugs we know about and ignore.

+The default `docker compose up` launches a single container that runs
+both the Next.js HTTP server AND the pg-boss worker. That works fine
+for a personal deployment but is hard to scale horizontally because
+every replica also runs the full reminder/insight cron schedule.
+
+v1.4 introduces an environment-variable gate so the same image can be
+deployed in three modes:
+
+| `HEALTHLOG_PROCESS_TYPE` | Web | Worker | Use when                  |
+| ------------------------ | --- | ------ | ------------------------- |
+| `all` (default)          | ✅  | ✅     | single-host self-hosting  |
+| `web`                    | ✅  | ❌     | scaling HTTP horizontally |
+| `worker`                 | ❌  | ✅     | dedicated job worker      |
+
+## How to split
+
+1. Edit `docker-compose.yml`: set `HEALTHLOG_PROCESS_TYPE=web` on the
+   `app` service and uncomment the `app-worker` service block at the
+   bottom (it ships with `HEALTHLOG_PROCESS_TYPE=worker` baked in).
+2. Make sure both containers see the same `DATABASE_URL`,
+   `ENCRYPTION_KEY` (or `ENCRYPTION_KEYS`), `API_TOKEN_HMAC_KEY`,
+   and `SESSION_SECRET`.
+3. `docker compose up -d --build`.
+
+Both containers connect to the same Postgres. pg-boss claims jobs
+atomically via row-level locking, so it is safe to run multiple worker
+replicas — they will share the load.
+
+## Healthchecks
+
+- `app` (web) healthcheck: `wget /api/version` every 30s.
+- `app-worker` does not expose a port; its liveness is reported into
+  the `worker_status` table on every reminder pass and surfaced through
+  `/api/admin/worker-status`.
+
+The web container does NOT depend on the worker, and vice versa, so
+neither container's startup can deadlock the other. The shared
+dependency is Postgres; both wait on `db: condition: service_healthy`.
+
+## Caveats
+
+- Background tasks that touch user-scoped Wide Events (e.g. reminder
+  notifications) emit telemetry from the worker; configure `LOKI_*`
+  env vars on the worker if you want them.
+- The off-host backup job runs in the worker only. The admin
+  `POST /api/admin/backup/test` endpoint runs in the web container and
+  exercises the same S3 credentials — set `BACKUP_*` env vars on BOTH.
+- The startup gate (`assertSubsystemEnabled`) refuses to boot the
+  reminder worker when `HEALTHLOG_PROCESS_TYPE=web`, so an accidental
+  cross-mode invocation aborts immediately instead of silently doubling
+  cron load.

+
+---
+
+## 1. Foundations
+
+### 1.1 Theme
+
+HealthLog is a Dracula-themed app with a light counterpart (Alucard). Both
+themes share the same six-color signal palette (purple, pink, green, cyan,
+orange, red, yellow, lavender), exposed as CSS variables and as Tailwind
+`dracula-*` color tokens. Use the semantic tokens (`--primary`,
+`--destructive`, `--card`, …) for chrome and the `--dracula-*` tokens for
+data viz only.
+
+| Surface                      | Token              |
+| ---------------------------- | ------------------ |
+| App background               | `--background`     |
+| Card / popover surface       | `--card`           |
+| Primary action               | `--primary`        |
+| Destructive action           | `--destructive`    |
+| Secondary / muted background | `--secondary`      |
+| Border                       | `--border`         |
+| Focus ring                   | `--ring`           |
+| Chart series 1–5             | `--chart-1`…`-5`   |
+| Brand signal: purple         | `--dracula-purple` |
+| Brand signal: green (good)   | `--dracula-green`  |
+| Brand signal: orange (warn)  | `--dracula-orange` |
+| Brand signal: red (alert)    | `--dracula-red`    |
+| Brand signal: cyan (info)    | `--dracula-cyan`   |
+
+Dark mode is the default. The theme switcher in the sidebar three-dot menu
+toggles `.dark` / `.light` on `:root`. Always test both modes before
+shipping a component.
+
+### 1.2 Spacing
+
+Tailwind's default 4-pixel scale. Reach for these stops first:
+
+| Use                                  | Token         | Pixels |
+| ------------------------------------ | ------------- | ------ |
+| Inline gap between icon and label    | `gap-1`       | 4      |
+| Tight stack inside a card            | `gap-2`       | 8      |
+| Default form-field stack             | `space-y-3`   | 12     |
+| Section block (heading + body)       | `space-y-4`   | 16     |
+| Page section separator               | `space-y-6`   | 24     |
+| Dashboard tile-row gap, hero spacing | `gap-4`       | 16     |
+| Page-edge padding (mobile / desktop) | `px-4 / px-6` |        |
+
+Avoid arbitrary `space-y-5`, `gap-3.5`, etc. unless aligning to a fixed
+external constraint.
+
+### 1.3 Typography
+
+The app uses the Tailwind defaults inherited via shadcn/ui. Reach for
+these classes first:
+
+| Use                                | Class                                   |
+| ---------------------------------- | --------------------------------------- |
+| Page title (h1)                    | `text-2xl font-semibold tracking-tight` |
+| Section heading (h2)               | `text-lg font-semibold`                 |
+| Card title                         | `text-base font-medium`                 |
+| Body text                          | `text-sm`                               |
+| Muted helper / metadata            | `text-sm text-muted-foreground`         |
+| Microcopy / footer                 | `text-xs text-muted-foreground`         |
+| Tabular data (latency, large nums) | `font-mono tabular-nums`                |
+
+Never use `font-bold` for emphasis — bump to `font-semibold` instead and
+let the design system breathe.
+
+### 1.4 Radius and elevation
+
+`--radius: 0.625rem` (10px) is the default. The Tailwind tokens
+`rounded-md` (`--radius-md` ≈ 8px) and `rounded-lg` (`--radius` ≈ 10px)
+cover 95% of cases. Use `rounded-2xl` only for hero cards or large
+modals.
+
+Elevation is achieved via `shadow-xs`, `shadow-sm`, or
+`shadow-[0_1px_0_rgba(255,255,255,0.04)]` for very subtle separators on
+dark backgrounds. Avoid Tailwind's heavy shadows (`shadow-lg`+) in chrome.
+
+---
+
+## 2. Components
+
+This section is **prescriptive, not exhaustive**. Each entry pairs a
+Radix/shadcn primitive with the cases it's the right answer for and the
+cases where another primitive should win.
+
+### 2.1 Buttons
+
+Every button comes from `@/components/ui/button`. Pick by purpose:
+
+| Purpose                                               | Variant       | Size              |
+| ----------------------------------------------------- | ------------- | ----------------- |
+| Primary action on a page or dialog                    | `default`     | `default`         |
+| Cancel, dismiss, secondary action next to primary     | `outline`     | `default`         |
+| Tertiary in-row action (edit, copy, snooze)           | `ghost`       | `sm`              |
+| Destructive (delete, revoke, disconnect)              | `destructive` | `default` or `sm` |
+| Icon-only action (toolbar, chart toggles, table rows) | `ghost`       | `icon-sm`         |
+| Inline link to external help docs                     | `link`        | `sm`              |
+| Toolbar / table row action when space is tight        | `outline`     | `xs`              |
+
+**Position rules.**
+
+- Forms (full-width or modal): primary on the **right**, cancel/back on
+  the **left**. Match shadcn dialog defaults.
+- Settings sections: a single sticky `Save` button at the **right end**
+  of the section header _or_ per-row inline `Save`. Never both in the
+  same section.
+- Test buttons (Telegram test, AI ping, etc.): immediately to the right
+  of the related Save / Apply control. Never below — keeps the eye
+  motion horizontal.
+- Destructive actions live in their own confirm dialog with a
+  type-to-confirm input when the action is irreversible (delete account,
+  revoke API token, drop user data).
+
+**Disabled state.** A disabled button must always come with a tooltip or
+helper text explaining why. Silent disabled buttons frustrate users.
+
+### 2.2 Inputs and forms
+
+We use `react-hook-form` + Zod schemas from `src/lib/validations/`.
+Wrap inputs in `<label>` (visible) plus `aria-describedby` for helper text.
+
+- **Text / number / email**: `<Input>`. Always set `autocomplete`. See §4.4.
+- **Multi-line**: shadcn `<Textarea>` (add via `pnpm dlx shadcn@latest add textarea` if missing).
+- **Single choice ≤4 options**: prefer `<RadioGroup>` or a SegmentedControl
+  pattern using `<Tabs>`. Never use `<Select>` for tiny enums — extra clicks.
+- **Single choice 5–15 options**: `<Select>` (shadcn).
+- **Single choice >15 options**: `<Combobox>` (shadcn `<Command>` + `<Popover>`)
+  with type-ahead.
+- **Multi choice**: `<Checkbox>` group, or shadcn `<MultiSelect>` when 7+ choices.
+- **Date / datetime**: shadcn `<Calendar>` inside a `<Popover>`. Always
+  label the timezone (Europe/Berlin).
+- **Numeric range**: `<Slider>` only when the value space is continuous
+  _and_ the user routinely sweeps. For most thresholds and counts, an
+  `<Input type="number">` plus stepper buttons is faster and less
+  fiddly. See §6 (Slider audit) for the migration path.
+- **Boolean toggle**: `<Switch>` for "applies immediately" settings (e.g.
+  enable Telegram). `<Checkbox>` for "applies on Save" lists (e.g. select
+  measurements to export).
+
+**Validation.** Inline messages below the field. Field gets
+`aria-invalid="true"` and a destructive border. Form-level errors land
+in a `<Alert variant="destructive">` at the top. Never show a toast for
+a field-level error.
+
+### 2.3 Dialog vs Sheet vs Drawer
+
+The wrong choice here is the most visible UX mistake we make. Pick by
+intent, not by hand-feel.
+
+| Use                                                             | Primitive                      | Rationale                                                        |
+| --------------------------------------------------------------- | ------------------------------ | ---------------------------------------------------------------- |
+| Confirm a destructive or irreversible action                    | `Dialog` (`AlertDialog` shape) | Modal blocks accidental dismiss; user must read.                 |
+| Inspect a single item's details with no edit                    | `Dialog`                       | Centered, focused, dismissible.                                  |
+| Edit a single item with ≤6 fields                               | `Dialog`                       | Tight focus, quick save.                                         |
+| Edit a single item with 7+ fields, or with deep sub-sections    | `Sheet` (right)                | Wide working surface, scrollable, doesn't crop on tall content.  |
+| Mobile bottom-up sub-action (filter, sort, multi-select picker) | `Sheet` (bottom)               | Thumb-friendly, dismiss by swipe.                                |
+| Multi-step wizard                                               | Full route                     | Page transitions communicate progress better than a stuck modal. |
+| Side-by-side compare or trend deep-dive                         | Full route                     | Charts need the viewport.                                        |
+
+Never nest Dialogs. If a Dialog needs another modal action, escalate the
+inner step to a separate route or use shadcn's `<AlertDialog>` chained on
+top of a `<Sheet>`.
+
+### 2.4 Cards and lists
+
+- **Card**: a self-contained unit of content. Use `<Card>` from
+  shadcn. Header, body, footer follow Pretendard-style hierarchy.
+- **Tile**: a _small_ card showing a single metric on the dashboard.
+  See §3.2 for the one-row constraint. Tiles must include current value,
+  unit, optional sparkline, and a single tap-target area.
+- **List row**: `<div className="flex items-center justify-between gap-3 px-3 py-2 hover:bg-accent/40 rounded-md">` — left side has icon + primary
+  - meta, right side has trailing controls. Never put primary actions in
+    the right-side ellipsis menu — only secondary or destructive.
+- **Empty state**: every list and tile has an explicit empty-state
+  component with an icon, a one-sentence explanation, and a single
+  primary action ("Add measurement", "Connect Withings"). See §5.
+
+### 2.5 Tables
+
+`<Table>` (shadcn) for tabular data only — measurements list, audit log,
+admin views. Default to `<Card>` + list rows for everything else;
+tables on mobile collapse poorly. When you must use a table on mobile,
+swap to a vertical list at `sm:` breakpoint.
+
+### 2.6 Status indicators
+
+Use the same color taxonomy across the app:
+
+| State     | Color token          | Examples                                       |
+| --------- | -------------------- | ---------------------------------------------- |
+| Good      | `--dracula-green`    | Connected, in target, healthy                  |
+| Info      | `--dracula-cyan`     | Up-to-date, neutral signal                     |
+| Caution   | `--dracula-orange`   | Mildly out of range, expiring token, slow sync |
+| Alert     | `--dracula-red`      | Out of range, sync failed, critical            |
+| Pending   | `--muted-foreground` | Loading, indeterminate                         |
+| Highlight | `--dracula-purple`   | New / featured / promoted                      |
+
+Show a colored dot **plus** a label. Never rely on color alone.
+
+---
+
+## 3. Layouts
+
+### 3.1 Page shell
+
+Every authenticated page is wrapped by `<TopBar>` + `<SidebarNav>` (left)
+
+- `<BottomNav>` (mobile). Don't reinvent these on a per-page basis.
+
+* Mobile breakpoint: `<sm` shows bottom-nav, hides sidebar.
+* `sm`–`md`: sidebar in icons-only mode.
+* `md+`: sidebar full mode unless user has collapsed it
+  (`localStorage:healthlog-sidebar-collapsed`).
+
+Page content goes in `<main className="mx-auto max-w-5xl px-4 sm:px-6 py-6 space-y-6">` unless the page is a full-bleed dashboard or settings shell.
+
+### 3.2 Dashboard tiles — one-row rule
+
+Tiles at the top of the dashboard live in a **single row**. Width caps
+at the chart's width directly below. **Never** wrap to a second row.
+
+If the user enables more tiles than fit, the dashboard surfaces a banner
+inviting them to deactivate or reorder via Settings → Dashboard. The
+layout editor in Settings shows a live preview of the constraint and
+flags overflow before save.
+
+CSS: `grid-cols-N` where N = active tile count, capped by
+`Math.min(activeTiles, maxTilesForViewport(width))`. Drag-reorder via
+`@dnd-kit/sortable`. Toggle-show via the layout editor only — not in the
+tile itself, to avoid accidental hide.
+
+### 3.3 Settings — `/settings/[section]`
+
+The 1.4 release splits the legacy 3150-LOC settings monolith into one
+route per top-level section:
+
+- `/settings/account` — profile, password, passkeys, account deletion.
+- `/settings/integrations` — Withings, moodLog, Telegram, ntfy, Web Push.
+- `/settings/notifications` — channel matrix + quiet hours + reminders.
+- `/settings/dashboard` — tile layout editor, default ranges, threshold
+  overrides.
+- `/settings/ai` — AI provider selection + connection + test.
+- `/settings/api` — API tokens for headless ingest + Bearer issuance.
+- `/settings/advanced` — exports, imports, danger zone.
+- `/settings/about` — version, build, license, links to docs/changelog.
+
+Each section's component lives at `src/components/settings/<section>.tsx`
+and stays under 400 LOC. Cross-section search lives in the section
+sidebar header.
+
+The legacy `/settings` route 301-redirects to `/settings/account`.
+
+### 3.4 Admin — `/admin/[section]`
+
+Same shape as Settings, with the right-hand sidebar listing:
+
+- Users
+- Integrations status
+- Monitoring (Wide Events, GlitchTip, Umami)
+- Backups
+- Maintenance
+- Audit log
+
+Status badges use the §2.6 color taxonomy. Each section opens to a card
+grid, never a long fluid list.
+
+---
+
+## 4. Patterns
+
+### 4.1 Loading states
+
+- **Page-level**: a `<Skeleton>` matching the final layout. Never show a
+  full-screen spinner. Mount the skeleton inside the same `<main>` shell
+  the loaded page renders into.
+- **Inline**: button loading state shows a spinner + label change
+  ("Saving…", "Testing…"). Disable other form controls while pending.
+- **Long-running**: progress bar with a remaining-step count; for
+  background tasks (export, backup), surface in a toast that links to
+  the operation log instead of blocking the UI.
+
+Skeletons must respect `prefers-reduced-motion: reduce`.
+
+### 4.2 Empty states
+
+A reusable `<EmptyState>` shape:
+
+```tsx
+<EmptyState
+  icon={<Plus className="size-6" />}
+  title={t("empty.measurements.title")}
+  description={t("empty.measurements.description")}
+  action={<Button>{t("empty.measurements.add")}</Button>}
+/>
+```
+
+Every list, every chart, every dashboard tile that can be empty has an
+explicit, translated empty-state. No "No data" placeholder strings.
+
+### 4.3 Error states
+
+- **Form errors**: inline below the offending field; aggregate at the
+  top of the form for global errors (e.g. "Server unreachable").
+- **Page errors**: Next.js `error.tsx` boundaries with a friendly
+  recovery action ("Retry", "Go home"). Send the error to GlitchTip
+  through the existing client.
+- **Network errors during save**: `<Alert variant="destructive">` at
+  the top of the form _plus_ a retry button. Never silently fail.
+
+### 4.4 Forms and password managers
+
+- Measurement, medication, and mood form fields use
+  `autocomplete="off"` on every input that browsers keep guessing wrong.
+- API-token inputs and AI-provider key inputs use
+  `autocomplete="new-password"` so the browser doesn't autofill the
+  user's account password.
+- Honey-pot fields (offscreen `<input>` with `autocomplete="email"` and
+  `tabIndex={-1}`) sit at the top of measurement forms to catch
+  aggressive autofill.
+- Forms always include a hidden `<input type="text" name="username"
+autocomplete="username" value={user.email} readOnly tabIndex={-1}>`
+  inside password change and passkey screens so password managers
+  attribute saved credentials correctly.
+
+### 4.5 Test buttons (every integration)
+
+Each configurable integration ships a Test button next to its Save
+control. Behavior:
+
+- **Trigger**: ad-hoc API call to the integration with a small,
+  identifiable payload ("HealthLog test ping").
+- **State**: button shows a spinner with localized "Testing…" label.
+  Result lands inline in a `<StatusCallout>` directly below — green for
+  success with the relevant detail (last sync, message ID, response
+  status) or red for the error (sanitized message — never leak the
+  upstream URL or API key).
+- **History**: each test writes a row to a tiny per-integration log
+  visible in the section. Last 5 tests, timestamp + result.
+- **Coverage**: required for Telegram, ntfy, Web Push, AI provider,
+  Withings, moodLog, GlitchTip, Umami, email (when wired), backup
+  target. Headless E2E asserts presence + working call for each.
+
+### 4.6 Server actions and mutations
+
+We use `react-hook-form` + TanStack Query mutations, never raw fetch
+calls in components. Every mutation:
+
+1. Optimistically updates the cache with a rollback handler.
+2. Toast on success ("Saved" — translated) and on error (with retry).
+3. Re-validates queries it touches.
+
+For multi-step flows, write a typed `apiClient` helper in
+`src/lib/api/clients/` rather than re-doing fetch in three places.
+
+### 4.7 Inline help
+
+A small `?` `<Tooltip>` next to the label is the default for non-trivial
+fields (e.g. "Why does this default to ESH 2023?"). Tooltips must be
+keyboard-accessible (Radix handles this) and translated.
+
+For long explanations, link out to `https://docs.healthlog.dev/...` —
+never embed multi-paragraph help inline.
+
+---
+
+## 5. Accessibility
+
+We aim for **WCAG 2.1 AA**, with the following non-negotiables:
+
+- Color contrast ≥ 4.5:1 for normal text, 3:1 for large text and UI
+  components. Verified by `@axe-core/playwright` in CI on every page.
+- Touch targets ≥ 44×44 CSS px on bottom-nav and primary action buttons
+  (WCAG 2.5.5).
+- Focus is always visible: shadcn's `focus-visible:ring` is preserved on
+  every customized component.
+- Every interactive element has an accessible name. Icon-only buttons
+  get `<span className="sr-only">` labels and `aria-label`.
+- `prefers-reduced-motion: reduce` disables animations beyond a 200 ms
+  fade.
+- Charts include text-equivalent summaries (`aria-describedby` linked to
+  a `<p className="sr-only">` summary) and exposed data via the visible
+  legend / table view toggle.
+
+CI fails on any `serious` or `critical` axe-core violation.
+
+---
+
+## 6. Slider audit and migration
+
+Sliders look pretty but are a poor fit for most numeric inputs because
+they sacrifice precision. The 1.4 audit catalogues every `<Slider>` in
+the codebase and migrates the inappropriate ones:
+
+| Setting                             | Current control | Better control                  |
+| ----------------------------------- | --------------- | ------------------------------- |
+| Mood intensity (0–10)               | Slider          | SegmentedControl                |
+| Notification quiet-hours range      | Two sliders     | Two `<Input type="time">`       |
+| Threshold-override numeric values   | Slider          | `<Input type="number">` + steps |
+| AI insight depth (1–5 levels)       | Slider          | `<RadioGroup>` cards            |
+| Export retention days (7/30/90/365) | Slider          | `<Select>` with preset options  |
+
+A slider stays appropriate for "scrub through history" or "set chart
+zoom range" — operations where the value is continuous and live preview
+is the point.
+
+---
+
+## 7. Internationalization
+
+All user-facing strings come from `messages/en.json` (default) and
+`messages/de.json`. Use `useTranslations()` on the client and
+`getServerTranslator()` (`src/lib/i18n/server-translator.ts`) on the
+server. Numbers, dates, currencies, and units always go through
+`useFormatters()` — never hand-roll `Intl.NumberFormat(...)` with a
+fixed locale.
+
+Server-rendered content (PDFs, notifications, server-issued category
+labels) must use the locale of the user the content is for, not the
+locale of the request that triggered the job.
+
+---
+
+## 8. Motion
+
+Default transitions: `transition-all duration-150 ease-out`. Heavier
+animations (insight cards, dialog enter/exit) use the shadcn defaults.
+Reduce-motion always wins.
+
+Loading skeletons pulse via Tailwind `animate-pulse`. Don't introduce
+custom keyframes without adding a `prefers-reduced-motion` fallback.
+
+---
+
+## 9. Component checklist (for new features)
+
+Before opening a PR for a new component or page, walk through:
+
+- [ ] Uses tokens from §1, not hard-coded hex/rgba.
+- [ ] Buttons follow §2.1 variant + position rules.
+- [ ] Inputs follow §2.2; correct `autocomplete`; honey-pots where needed.
+- [ ] Dialog vs Sheet vs Drawer per §2.3.
+- [ ] Loading, empty, and error states from §4.1–4.3 implemented.
+- [ ] All strings via `t()`; numbers via formatters.
+- [ ] Mobile viewport tested (Chrome DevTools 375×667 and 414×896).
+- [ ] Light + Dark mode tested.
+- [ ] Keyboard navigation: Tab order, Enter to submit, Esc to dismiss.
+- [ ] axe-core clean (no serious/critical).
+- [ ] Headless screenshot test added if UI is non-trivial.
+
+---
+
+_Maintained as part of the v1.4 release cycle. Propose changes alongside
+the code that motivates them._
