Marc-André Bombeck f5962497d6 v1.4.34.4 — audit-driven hotfix bundle (security, UX, code-quality, docs)
Consolidated hotfix landing the findings from a six-axis audit
covering mobile security, UX + accessibility, code quality + docs,
README + discoverability, web performance, and mobile-deep responsive
behaviour. None of the changes break the public API or the existing
data shape; every fix is additive and SAFE under the v1.4.34.x web
freeze. Full audit reports live in `.planning/round-audit-*.md`.

Security
  - Password rotation now wipes API tokens + refresh tokens in the
    same `$transaction` as session revocation. A stolen iOS Bearer no
    longer survives a user-initiated password change or an admin reset.
  - `/.well-known/` proxy bypass tightened to an explicit-allowlist
    `Set`. Stale `/api/auth/codex/callback` PUBLIC_PATHS entry dropped.
  - HSTS gains `preload`. Withings host removed from the global CSP
    and gated to the integration's own routes.
  - `getClientIp` warns once per process on `TRUST_PROXY_HOPS`/XFF
    mismatch + exposes a tagged helper for tighter universal buckets.
  - Service worker rejects off-origin notification-click URLs. Offline
    fallback body switched to a locale-neutral icon. Manifest gains
    `scope`, `id`, `display_override`.

UX + accessibility
  - i18n leaks closed on Dialog/Sheet close-X, ChartSkeleton's loading
    announcement, and the notifications-section breadcrumb.
  - Focus rings on bottom-nav, the More overflow button, and the
    mobile top-bar user menu.
  - Tap-target floor: Input / NativeSelect / Select / DateTimeInput
    switch to `h-11 sm:h-10`.
  - Admin chip-strip auto-scroll-into-view (matches v1.4.33 settings).
  - List-page subtitles visible on mobile.
  - Insights empty-state CTA vocabulary normalised so the link opens
    the right measurement form (was silently failing for
    BODY_TEMPERATURE / BLOOD_GLUCOSE / PULSE).

Mobile-deep
  - `viewport.themeColor` reacts to light/dark mode.
  - TopBar + Coach FAB reserve safe-area-inset-top / -bottom for
    notched iPhones.
  - Sonner toaster switches to `theme="system"`.

Code quality
  - `SESSION_SECRET` dropped — the env var was documented as required
    but never read by code. Three secrets, not four. Self-hosters
    upgrading can delete the existing line.
  - `toJson<T>()` helper consolidates seven Prisma JSON-cast sites.
  - `db-compat.ts` gains a header docstring naming it the
    schema-bootstrap path.
  - Passkey response types adopted from `@simplewebauthn/server`;
    `any` + eslint-disable pragmas drop out.
  - Zero-TODO CI gate added at `.github/workflows/no-todo-markers.yml`.

Documentation + discoverability
  - README rework: How-it-compares matrix, Apple Health + AI Coach
    promoted to standalone Key-Features bullets, status block, latest
    release + GHCR badges, OpenAPI pointer, three-secret Quick Start.
  - openGraph + twitter cards now carry `images` and a
    `summary_large_image` Twitter card.
  - GitHub repo metadata: description tightened from 290 to 156
    chars + keyword-front, `homepageUrl` flipped from a personal
    tenant to the demo site, six generic / PII-adjacent topics
    swapped for six high-intent ones.
  - Five new user-facing docs: `docs/self-hosting/getting-started.md`,
    `docs/self-hosting/reverse-proxy.md`,
    `docs/integrations/apple-health.md`,
    `docs/integrations/withings.md`,
    `docs/integrations/ai-providers.md`.
  - `docs/README.md` clarifies the docs tree as internal playbooks
    vs the user-facing `docs.healthlog.dev` site.

Marc-André BombeckandMarc-André Bombeck d7778c1085 feat(v1.4): multi-tenant prep — off-host backup, encryption-key versioning, worker/web split, native-Bearer UA gating (#135)
* feat(crypto): G2 — encryption-key versioning + rotation CLI

Adds backwards-compatible support for ENCRYPTION_KEYS (JSON map of
{ "id": "<key>" }) plus ENCRYPTION_ACTIVE_KEY_ID. Ciphertext format is now
"<keyId>.<base64payload>"; legacy bare-base64 ciphertext still decrypts
under the synthetic "v1" id derived from the existing ENCRYPTION_KEY.

scripts/rotate-encryption-key.ts re-encrypts every encrypted column on
User / WithingsConnection / AppSettings with the active key. Idempotent —
rows already on the active id are skipped.

Why: enables zero-downtime rotation when a key is suspected leaked,
without forcing every encrypted row through a single big-bang rewrite.

* feat(auth): G4 — native-Bearer UA gating + rotating refresh tokens

Web callers (UA contains 'Mozilla/') keep the legacy 90d Bearer when they
explicitly opt in via X-Client-Type: native. Native callers (HealthLog-iOS,
HealthLog-iPad, n8n, Health-Connect, unrecognised UAs) now receive a 24h
access token plus a 60d rotating refresh token in the login response.

New /api/auth/refresh endpoint atomically validates + rotates the refresh
token (one-time-use), revokes the previously paired access token, and
audit-logs every refresh + revoke. Reuse of an already-consumed refresh
token revokes the entire family for the user/device — defence against a
stolen refresh token.

Migration 0025_refresh_tokens adds the table; the only DDL is CREATE
TABLE so it is forward-compatible. Down migration documented at
docs/ops/migrations/0025-down.sql.

Why: the V3 audit (still-V2-A) flagged that 90d tokens are too long for
native callers when refresh-token rotation is now table-stakes for mobile
apps. Web flows are unchanged so existing browser sessions keep working.

* feat(infra): G3 — web/worker container split via HEALTHLOG_PROCESS_TYPE

Adds a tiny startup gate (src/lib/process-type.ts) so the same Docker image
can run as web-only, worker-only, or 'all' (default — single-container,
backwards compatible). assertSubsystemEnabled() refuses to boot the
reminder worker when HEALTHLOG_PROCESS_TYPE=web, preventing accidental
double-cron when an operator splits the deployment.

docker-compose.yml ships the optional app-worker service block commented
out so 'docker compose up' keeps working out of the box; uncommenting it
+ flipping app to HEALTHLOG_PROCESS_TYPE=web is the only change to scale
HTTP horizontally. Healthchecks are isolated per service so neither
startup deadlocks the other; both wait on db: service_healthy.

docs/self-hosting/scaling.md walks through when + how to split.

* feat(jobs): G1 — daily off-host encrypted backup to S3-compatible storage

New pg-boss queue 'data-backup-offhost' runs at 02:30 Europe/Berlin, dumps
each user's measurements + medications + intake events + mood entries,
encrypts the JSON under a SEPARATE key (BACKUP_ENCRYPTION_KEY, isolated
from the application ENCRYPTION_KEY), and uploads to any S3-compatible
target via @aws-sdk/client-s3.

Wire format documented in docs/ops/backup-restore.md:
  magic "HLBK" || version 0x01 || iv(12) || authTag(16) || ciphertext

The worker prunes objects older than BACKUP_RETENTION_DAYS (default 30);
operators are encouraged to also configure a bucket-level lifecycle rule.

Admin endpoint POST /api/admin/backup/test issues a 1-byte PUT+GET
roundtrip and returns endpoint + bucket + per-call latency. Credentials
are never returned.

scripts/restore-backup.ts downloads + decrypts a single object so
operators can verify the chain end-to-end without standing up a separate
restore harness.

Why: GDPR Art. 32 + V3 audit "data durability" — without an off-host copy
the only line of defence against a Postgres volume loss is the in-DB
DataBackup model on the same host. Separate-key isolation means a leak of
the application encryption key does not also expose every user's archive.

* fix(multi-tenant): address review findings — rotation coverage, hard decrypt errors, web/worker gates

Multi-agent review on PR #135 caught several CRITICAL + HIGH issues that
would have shipped silent data corruption or weakened the threat model:

Encryption + rotation
- scripts/rotate-encryption-key.ts: stop selecting `bugReportTokenEncrypted`
  (column doesn't exist in the schema; the script crashed on the AppSettings
  step). Add the three encrypted columns it was missing —
  NotificationChannel.config, PushSubscription.p256dh, PushSubscription.auth
  — so rotating to a new key actually re-encrypts every encrypted row.
  Without this, dropping the old key id from ENCRYPTION_KEYS would leave
  notification channels and web-push subscriptions permanently
  undecryptable.
- src/lib/crypto.ts: refuse to silently fall back to the active key when a
  legacy bare-base64 row is decrypted but no v1 entry is configured. Throws
  a clear "Restore ENCRYPTION_KEY (or add a v1 entry to ENCRYPTION_KEYS)
  and run scripts/rotate-encryption-key.ts before removing it" so an
  operator who pulled the v1 too early notices immediately instead of
  hitting opaque GCM tag errors.
- docs/ops/encryption-key-rotation.md: full step-by-step + rollback note +
  troubleshooting section. Spells out that rotation is a forward-only
  operation and what to do if the rollback path is needed.

Web / worker split (G3)
- src/proxy.ts: refuse HTTP traffic with a 503 +
  X-HealthLog-Process-Type: worker header when HEALTHLOG_PROCESS_TYPE=worker.
  The worker container (which still runs `node server.js` for now) no
  longer accepts requests, so a misrouted client gets a clear hint instead
  of a partially-served response.
- src/instrumentation.ts: short-circuit before importing the reminder
  worker when HEALTHLOG_PROCESS_TYPE=web — avoids the noisy
  "[instrumentation] CRITICAL" stderr line we emitted on every web boot.
- /api/version added to PUBLIC_PATHS so the compose healthcheck doesn't
  silently 302-redirect through the auth gate (the prior wget treated the
  login page as a 200 success and would never notice an unhealthy backend).

Refresh-token rotation (G4)
- src/lib/auth/refresh-token.ts: reuse-detection now revokes ALL active
  refresh tokens for the user, not only those scoped to the same deviceId.
  An attacker who rotated without an X-Device-Id header would otherwise
  keep their family alive on the no-device branch. Defence-in-depth.
- revokeRefreshToken() also revokes the paired access token so a leaked
  access token cannot outlive the refresh-token sibling that the caller
  just killed (logout-on-device).

Off-host backup (G1)
- src/lib/jobs/offhost-backup.ts: drop the worker-side DeleteObject path.
  Retention is the bucket's lifecycle-policy job; the worker keeps a
  PutObject + GetObject grant only. A compromised worker can no longer
  wipe the backup history. Per-user errors are now surfaced as Wide
  Event warnings + a structured failures[] array on the report so an
  operator can tell which user failed and why.
- scripts/restore-backup.ts: schema-validate the decrypted payload before
  writing to disk, plus an optional --user-id=<id> flag that refuses to
  proceed unless the dump's userId matches. Prevents silent
  cross-tenant restores when an operator points the script at the wrong
  S3 key.

Idempotency
- src/lib/idempotency.ts: the leak-guard already blocked `hlk_`
  (access-token prefix); also block `hlr_` so a future caller wrapping
  the new /api/auth/refresh endpoint with withIdempotency() can't
  accidentally cache a freshly-issued refresh token.

Migration / schema
- prisma/migrations/0025_refresh_tokens/migration.sql: wrap in a single
  transaction; switch to CREATE { TABLE | INDEX } IF NOT EXISTS so a
  partial-deploy retry is a no-op instead of "relation already exists";
  guard the FK ADD with information_schema lookup for the same reason.
- Schema replaces the single-column `@@index([deviceId])` with a
  composite `@@index([userId, deviceId])` (every lookup also filters on
  userId; the old index would never have been used). Comment on
  accessTokenHash corrected to HMAC-SHA-256.

Container / ops
- Dockerfile: install tzdata + ENV TZ=Europe/Berlin so the daily
  pg-boss schedule (`30 2 * * *` Europe/Berlin) actually fires at 02:30
  Berlin instead of silently falling back to UTC on the alpine base.
- docker-compose.yml: tighten the healthcheck to `wget --spider` (matches
  the Dockerfile HEALTHCHECK style, doesn't pipe the body), pass through
  BACKUP_RETENTION_DAYS so a custom retention env reaches the container.
- .env.example: document every new env var added in this PR
  (HEALTHLOG_PROCESS_TYPE, ENCRYPTION_KEYS, ENCRYPTION_ACTIVE_KEY_ID,
  BACKUP_S3_*, BACKUP_ENCRYPTION_KEY, BACKUP_RETENTION_DAYS) with
  comments and the all-or-none semantics for the backup block.

491 tests still green, typecheck clean.

* chore: retrigger CI
