Marc-André Bombeck 4ca3de5ff3 fix(medications): make the nightly dedup and the pin path respect each other
A deliberately detached ad-hoc intake could be folded back into its slot
cluster by the nightly dedup, and a pinned row could lose its slot to a
sibling on the sync-version tiebreak — pins now outrank every other row
and detached rows never join a cluster, mirrored into the operator
repair script. Pinning onto an already-served slot no longer overwrites
the existing record silently; the API refuses with a clear error while
an identical re-post stays idempotent. The idempotency cache also
refuses to store invite-token-shaped responses.

Marc-André BombeckandClaude Opus 4.8 ae468edca2 fix(idempotency): claim the key before running the side-effect
findCached returned null and the response was only persisted after the
handler completed, so two concurrent requests carrying the same
Idempotency-Key both passed the lookup and both executed the side-effect
(duplicate writes for the very clients idempotency protects).

Claim the key by inserting a pending sentinel row under the existing
(userId, key, method, path) unique constraint before the handler runs.
A racing request either finds the pending row or loses the insert race
and is refused with 409. The claim is promoted to the completed response
on a cachable result, released on a non-cachable result or a
secret-shaped body, and released on a handler throw. The pending row
carries a short claim TTL so a crashed handler self-heals and the
existing expiry-sweep cleanup still applies.

Marc-André Bombeck 93694cacd0 fix(idempotency): scrub hls_ share-link tokens from cached bodies
The body-content secret guard matched hlk_ / hlr_ / sk- but not the
new hls_ clinician share-link prefix, so a response echoing a freshly
minted share token could be persisted to the idempotency cache. Add
hls_ to SECRET_PATTERN alongside the existing token prefixes.

Marc-André BombeckandClaude Opus 4.7 67575180b8 fix(qa): apply pre-release multi-agent QA findings
Three small follow-ups surfaced by the v1.4.6 QA pass:

- Settings → KI: the "raw data" warning still used raw Tailwind orange
  tokens instead of the Dracula `dracula-orange` ones, breaking theme
  consistency and tipping below the WCAG-AA contrast floor on the
  card surface.
- Admin status grid: the Backups card cta read "View backups" but
  jumped to the system-status section (the dedicated backups view
  does not exist yet — that's a v1.5 feature). Re-labelling the cta
  to "Open system status" and the Integrations cta to "Open
  integrations" makes the destination honest. The href targets
  themselves are unchanged.
- `withIdempotency` body-content guard previously did `text.includes("sk-")`
  which silently broke caching for benign payloads containing common
  English compounds like "task-id", "risk-management", "disk-io".
  Tightened to a regex requiring the canonical secret prefix plus a
  realistic suffix length, so only actual API keys trip the guard.
  Three regression tests cover the false-positive cases.

Marc-André BombeckandClaude Opus 4.7 c7b600575e fix(idempotency): refuse to cache bodies containing third-party AI keys
P12. The body-content guard already rejected `hlk_` / `hlr_` (our access
and refresh tokens). Extend it to also reject `sk-` so any OpenAI or
Anthropic key that might be echoed by a misrouted handler never lands
in the IdempotencyKey table. The substring match also covers `sk-ant-`
so we don't need a second branch.

Adds a parametrised vitest case asserting all four prefixes
(hlk_, hlr_, sk-, sk-ant-) suppress caching, plus a
positive case to prove a normal payload still caches.

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.

Marc-André BombeckandClaude Opus 4.7 98a57eb786 audit(v1.3.3): SpO2 + body-composition + 14 CRITICAL/HIGH security/correctness fixes (#121)
* fix(measurements): close issue #109 + sync body composition across UI/PDF/thresholds

User-visible: TOTAL_BODY_WATER, BONE_MASS, and BLOOD_GLUCOSE now appear in
the measurements filter, badge, mobile icon, and edit dialog (issue #109).
Server-rendered doctor report now includes body composition rows (audit
C-9). Body water + bone mass have proper effective-range thresholds so
severity logic doesn't silently return `nominal` (audit C-15).

Structural: extracted the per-type display maps from measurement-list.tsx
into measurement-list-meta.ts as a deliberate first step toward the
single-source manifest planned for phase P5. Coverage tests now fail-fast
if a future enum addition skips any of: list label/icon/color, doctor-PDF
label/unit/vital-types, chart label, threshold metric order/label/bounds.

Audit-2026-05-07 / phase P0:
- closes #109 (filter UI gap, root cause for the German raw-enum display)
- closes audit C-9 (server PDF used a stale type map)
- closes audit C-15 (no warn/critical bands for body composition)

Tests: 282 → 296 (14 new). Typecheck clean.

* docs: align OpenAPI spec + migration comment with body-composition reality

- OpenAPI MeasurementType enum: add TOTAL_BODY_WATER + BONE_MASS (was at
  v1.3.0 baseline; spec drifted past the v1.3 server release)
- Bump openapi version 1.3.0 → 1.3.2 to match package.json
- Migration 0022 comment: TOTAL_BODY_WATER stores kg (water content),
  not percent of body weight. Validators (VALUE_RANGES) and the Withings
  client (type 77 → kg) treat it as kg already; the comment was the lone
  outlier and would mislead the next reviewer.

Audit-2026-05-07 / phase P1a — closes audit M-B1 (partial; OpenAPI enum)
and M-B2 (migration unit comment).

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(security): close 3 audit CRITICALs (Withings header / idempotency Bearer / GlitchTip URL strip)

C-3 (Withings webhook secret in URL):
Now reads X-Withings-Webhook-Secret header in preference; URL ?secret=…
fallback retained for legacy Withings configurations and emits a Wide
Event warning so operators can spot still-using-the-old-flow integrators.
The query-string secret was leaking into Coolify access logs and any
GlitchTip event whose request.url got captured.

C-4 (idempotency dead for Bearer-token clients):
The default userIdResolver only consulted getSession(). Bearer-authed
clients (the iOS / n8n / headless-API fleet that PR #117 was built for)
fell through, so every retry created duplicate measurements. The default
now tries cookie session first, then Bearer token via
hashToken+apiToken.findUnique with revoked/expiry checks. All three
existing call sites (measurements, mood-entries, medications/intake) get
the fix automatically.

H-B7 (request.url with secrets shipped to GlitchTip):
reportToGlitchtip now strips the query string before forwarding the URL,
so Withings legacy ?secret=… and any OAuth ?code=… that errors during
the callback don't end up in someone else's incident UI.

Audit-2026-05-07 / phase P2.
Tests: 296 → 301 (5 new in idempotency.test for the Bearer fallback +
revoked/expired/null cases).
Deferred to a follow-up (needs DB migration / lock primitive):
  C-2  moodLog webhook → AES-GCM at rest + HMAC-over-body
  C-5  idempotency TOCTOU advisory_lock or in-flight sentinel row

* feat(measurements): add OXYGEN_SATURATION (SpO2) as first-class measurement type — v1.3.3

Closes the OxygenSaturation feature request from #109.

- Migration 0024 extends MeasurementType enum (additive, IF NOT EXISTS)
- Zod validators: plausibility 50–100% (below 50 is incompatible with
  sustained life; above 100 is physically impossible)
- effective-range thresholds: green 95–100, orange 92–94, red <92.
  Sources: BTS Guideline 2017 (target 94–98%), ATS clinical practice
  (≥95% at rest is healthy), AHA/clinical literature (<92% = call
  provider, <88% = ER). Lower-only concern — upper orange wing
  collapses to greenMax since saturation cannot exceed 100%.
- Personalisation: existing thresholds-override UI lets COPD /
  chronic-respiratory users with a doctor-set 88–92 baseline tune the
  bands. METRIC_ORDER + METRIC_LABEL_KEYS extended in
  thresholds-section.tsx; the exhaustive `Record<ThresholdMetric>`
  forces TS to catch any missed surface.
- Withings ScanWatch type 54 mapping (best-effort — only fires for
  pulse-ox-capable devices).
- Wired through measurement-form, measurement-list-meta (icon: Wind),
  health-chart, both doctor-report-pdf renderers (core + browser-side
  near-duplicate), OpenAPI spec (version 1.3.0 → 1.3.3), and i18n in
  4 sections × 2 locales.
- iOS DTO already declared `OXYGEN_SATURATION` — server enum addition
  closes the long-standing drift flagged in audit V2.
- 4 new tests: numeric green band, upper-wing collapse,
  user-override (COPD baseline), METRIC_BOUNDS shape.

Tests: 301 → 305. Typecheck: clean.

Audit-2026-05-07 / v1.3.3 / closes #109 SpO2 feature request.

* fix(analytics): truthfulness pass on medical citations + clamp override orangeMax

Doctor-agent + hallucination-hunter audit V3 found six medical citations
in effective-range.ts that the code did not actually implement. Plus a
latent bug in the user-override path that produced physically-impossible
orangeMax values (>100% saturation, <0% body-fat).

Citation rewrites (no numeric changes):

- ACTIVITY_STEPS: "WHO ≥8000 steps/day" → Saint-Maurice JAMA 2020.
  WHO publishes activity in min/week, not steps. Step-count was a
  misattribution that also leaked into AI prompts.
- TOTAL_BODY_WATER: "ESPEN Body Composition Guidance 2017" → Watson
  formula / ICRP Reference Man. ESPEN 2017 is BIA practice guidance,
  it does not publish kg cut-offs.
- BONE_MASS: "DEXA-equivalent bone mineral content" → "Bioimpedance-
  estimated; not DEXA-comparable". Withings BIA values typically run
  5–7% below DEXA — calling them DEXA-equivalent in a doctor-report
  PDF was a real legal-exposure misattribution.
- OXYGEN_SATURATION: "BTS Guideline 2017 (target 94–98%) + ATS
  clinical practice (≥95% at rest is healthy)" → "consumer pulse-
  oximeter consensus (≥95% normal at rest); slightly tighter than
  BTS 2017 (94–98%); NICE NG115 ≤92% escalation, BMJ panel / FDA
  pulse-oximeter labelling ≤88% ER threshold". Code uses 95-100/92-100
  band — that's an ATS/consumer-consensus number, not BTS's literal
  94-98 target. Soften the citation to match the code, not vice versa.

Bug fix (1 latent, 1 real-today):

- effective-range override path now clamps orangeMin/orangeMax to
  METRIC_BOUNDS.{min,max}. Without the clamp, a COPD user setting
  SpO2 override to {95,100} emitted orangeMax = 100.75 (impossible
  saturation), and a BODY_FAT override of {2,80} emitted orangeMin
  = -9.7 (negative percent). Default-range case 210 already
  hard-coded orangeMax: 100 for the same reason — the override path
  was the only branch missing the invariant.

Tests: 305 → 306 (1 new: clamps override orangeMax to physiological 100%).
Typecheck: clean.

* fix(security): Bearer-scope wildcard handling + GDPR Art.17 account-delete erasure

Two CRITICAL fixes from audit V3.

NEW-V3-1: Bearer-scope bypass.
  apiToken.permissions ["*"] is meant to be the wildcard "session-equivalent"
  scope (the iOS app receives this on login). The previous check
    permissions.includes(requiredPermission)
  treated "*" as a literal string — never matched. Today many sensitive
  routes call requireAuth() *without* a requiredPermission, so a leaked iOS
  token can act as a full-scope token (account delete, settings wipe). Once
  those routes adopt requireAuth("scope:name"), this wildcard handling keeps
  the iOS app working while narrower-scoped tokens (e.g. user-issued
  ["medication:ingest"]) get correctly 403'd.

  Same wildcard handling added to the standalone permission checks in
  src/app/api/ingest/medication/route.ts:65, 119.

NEW-V3-2: GDPR Art. 17 account-delete erasure completeness.
  Feedback + AuditLog rows had `onDelete: SetNull` in the schema, which
  preserved PII (free-text symptom descriptions, IP addresses, login-city
  geolocation) after the user was deleted. We now explicitly
  prisma.feedback.deleteMany + prisma.auditLog.deleteMany before the
  cascade-delete, making account deletion genuinely complete erasure.

Tests 306/306 still pass; typecheck clean. Audit V3.

* test(pdf): real text-content assertions for body composition + SpO2 rows

Replaces bytes-only "renders body composition rows" theatre test with
pdf-parse-driven text extraction that asserts the actual rendered labels
+ values for TOTAL_BODY_WATER, BONE_MASS, OXYGEN_SATURATION (DE + EN).

Closes V3 audit finding STILL-V2-NEW-3: the previous test only verified
"%PDF-" header + byte-count, so a regression that drops a row would
still pass. Now a missing label fails the test.

- adds dev dep: pdf-parse@^2.4.5
- 308/308 tests pass (was 306, +2 SpO2 + EN-locale coverage)

* fix(measurements): close enum drift cousins — derive 5 type-arrays from canonical enum + extend 2 contract enums

V3 audit finding "enum drift cousins": 7 hardcoded module-level type arrays
silently dropped SpO2/TBW/BoneMass/BloodGlucose from their respective
domains. Adding a new measurement type required hunting these down.

Now all aggregation paths derive from `measurementTypeEnum.options`:
- /api/insights/comprehensive (AI insights)
- /api/dashboard/summary (iOS dashboard adapter)
- /api/analytics (analytics aggregator)
- /lib/insights/general-status (AI general-status fetch)
- /api/import (Zod schema — round-trip now covers all 11 types)

External-contract enums extended additively (no breakage for old clients):
- /api/measurements/series kindEnum: + oxygen, totalBodyWater, boneMass
- /api/dashboard/widgets widgetIdEnum: + oxygenSaturation
- DashboardWidgetId + DEFAULT_DASHBOARD_LAYOUT: + oxygenSaturation row
- formatMeasurementsForExport: glucoseContext now round-trips

Coverage test (`measurement-type-enum-coverage.test.ts`) asserts the
canonical enum stays the source of truth and documents PDF exclusions
(BLOOD_GLUCOSE renders via context section, SLEEP/STEPS lifestyle-only).

313/313 tests pass (was 308, +5 new).

* fix(security): close 6 V3-audit HIGH findings (CSP, web-push SSRF, IP geo, AI provider leak, import rate-limit)

- CSP: chatgpt.com + api.openai.com only on /settings/ai/** routes (was
  blanket connect-src on every page including /auth/login → DOM-XSS exfil
  channel)
- web-push: webPushSubscriptionSchema.endpoint requires HTTPS + isPublicUrl
  refinement; was z.url() only → blind SSRF probe via Push subscription
- isPublicUrl: also fixes a regression where DNS labels starting with
  "fc"/"fd" (fcm.googleapis.com etc.) were falsely classified as IPv6
  unique-local. Check is now gated on a colon being present in the host.
- /api/ai/test: stop returning provider err.message + bodyExcerpt to the
  client (leaked provider URLs / partial keys / internal headers). Now
  returns categorised generic message; full details land in the wide-event
  via annotate() for the operator.
- /lib/geo (auditLog IP geo lookup): switch default provider to
  ipwho.is over HTTPS, accept ipwho.is + ip-api pro response shapes,
  add IP_GEO_LOOKUP_DISABLED env, refuse non-HTTPS configured URLs.
  Previously leaked IP+timestamp over plaintext HTTP every auth event
  (GDPR Art. 32 + Art. 44).
- /api/import: add 5/hour rate-limit (was unlimited; bulk-injection vector)

Tests: 325/325 pass (was 313, +12 new — webPushSubscriptionSchema SSRF
guards, fc/fd-prefix domain regression, geo HTTPS-only, geo provider
shapes, geo opt-out env).

* fix(security,gdpr): trusted-proxy IP, audit-log retention, idempotency cachable filter, Bearer mock tightening

V3 audit follow-on bundle covering 4 HIGH findings.

(I) getClientIp — TRUST_PROXY_HOPS env (default 1) replaces blind XFF
trust. Reads chain right-to-left so client-supplied leftmost entries
cannot rotate the per-IP rate-limit bucket. Default 1 matches typical
single-proxy self-host (Coolify/Caddy/Cloudflare-Tunnel); 0 forces
x-real-ip / null. New 7-test suite covers the rotation attack +
malformed entries + zero-hop fallback.

(F) Audit-log retention job — daily 03:15 cleanup of audit_logs older
than AUDIT_LOG_RETENTION_DAYS (default 365). Closes GDPR Art. 5(1)(e)
"storage limitation" gap; previously IPs + city + login events
accumulated forever. 6-test suite covers default + override +
misconfig guard (rejects <7 days).

(G) isCachableStatus — extracted the inline 4xx/5xx filter into a
named, exported, tested function. 7 cases cover the full do-not-cache
contract (401 / 403 / 408 / 429 / any 5xx) and confirm 2xx + 4xx
validation are still cached.

(H) Bearer-mock tightening — apiToken.findUnique mocks in
require-auth-bearer.test + idempotency.test now assert the
where.tokenHash shape uses the hashed value (not the raw bearer).
A regression that switched back to raw-token comparison would have
been silent without this assertion.

Tests: 345/345 pass (was 332, +13 new).

* fix(security): encrypt moodLog webhook secret at rest with AES-256-GCM (V3 audit STILL-V2-C-2)

The mood_log_webhook_secret column previously stored a plaintext secret
that the webhook handler compared timing-safe against every enabled
user. A DB dump or backup snapshot leaked active webhook credentials.

New contract — no schema migration required:
- Writes go through encryptMoodLogSecret() (AES-256-GCM via existing
  crypto helper, ENCRYPTION_KEY).
- Reads go through readMoodLogSecret() which transparently decrypts
  envelopes and tolerates legacy plaintext rows during the transition
  (graceful upgrade path — no breaking change for self-hosted users).
- Webhook lookup decrypts each candidate before timing-safe compare.
- Status endpoint decrypts for the user's settings page.

One-shot startup migration in reminder-worker rotates any leftover
plaintext rows on next worker boot. Idempotent; encrypted rows are
skipped.

Tests: 350/350 pass (was 345, +5 new — round-trip, legacy passthrough,
isLegacyPlaintext semantics, rotateLegacy idempotence).

* docs: sync README + AGENTS + CLAUDE + CHANGELOG + OpenAPI for v1.3.3 (V3 audit doc-drift)

V3 audit Doku Specialist findings — drift between code and meta-docs.

- README §Key Features now mentions pulse oximetry (SpO₂) + Withings
  ScanWatch sync; Tech Stack model count corrected 23 → 25.
- AGENTS.md status promoted v1.3.2 → v1.3.3; vitest config corrected
  `vitest.config.ts` → `vitest.config.mts`; migration range corrected
  `0001–0022` → `0001–0024`; model count + list updated to 25 (adds
  Device, IdempotencyKey).
- CLAUDE.md model count updated (2 occurrences).
- CHANGELOG.md v1.3.3 expanded with Security + Internal sections that
  were missing the audit-fix-marathon work (Bearer-scope, account-delete
  cascade, moodLog encryption, CSP tightening, Web-Push SSRF, IP-geo
  HTTPS, AI-test leak fix, import rate-limit, trusted-proxy XFF,
  audit-log retention, idempotency cachable filter, Bearer mock
  tightening, enum-drift cousins, PDF text-content tests).
- OpenAPI Bearer description corrected `SHA-256 hashes` →
  `HMAC-SHA-256 hashes (keyed with API_TOKEN_HMAC_KEY)` so the docs
  match the actual server-side implementation. Wildcard scope contract
  documented.

* fix(audit-review): close 4 HIGH + 2 MEDIUM findings from multi-agent review pass

Multi-agent review of the audit-fix branch surfaced four HIGH issues
and a couple of MEDIUM hardenings. All addressed before merge.

HIGH-1 — OpenAPI MetricKind enum drift (iOS strict-decode crash risk).
The dashboard-summary route now emits totalBodyWater/boneMass/
oxygenSaturation MetricCards, but the spec still listed only the
original 7 kinds. Generated iOS Codable would have crashed the dash
the moment a user logged SpO2. MetricKind extended with the 3 new
kinds + comment documenting unknown-value defensive decoding.

HIGH-2 — kindEnum naming consistency on /api/measurements/series.
The series adapter shipped "oxygen" while the dashboard summary used
"oxygenSaturation"; both routes now use "oxygenSaturation" so iOS
decoders can share a single MetricKind type across endpoints.

HIGH-3 — /api/ai/test no-leak guard had no test. Added 4 tests that
mock provider errors with sk-leaked-key + provider URLs in the err
fields and assert the response body never echoes them, plus the
3-status-categorised generic messages (401/429/5xx/other).

HIGH-4 — /api/import 5/hour rate-limit had no test. Added 2 tests that
mock checkRateLimit allowed/disallowed and assert the 429 path uses
the right key shape (`import:<userId>`, 5, 1h) and that the within-
quota path proceeds.

MEDIUM-3 — getClientIp under-length XFF chain regression. With
TRUST_PROXY_HOPS=2 and a chain of length 1, the previous clamp
returned the leftmost (attacker-controlled) entry, silently
re-introducing the rotation attack the helper was meant to close.
Now: when chain is shorter than configured hops, refuse XFF entirely
(fall back to x-real-ip / null). Added regression test.

LOW-1 — TRUST_PROXY_HOPS=garbage now throws at boot instead of
silently degrading to hops=0. Added regression test.

Tests: 358/358 pass (was 350, +8 new). Typecheck clean.

Marc-André BombeckandClaude Opus 4.7 a8a7c19d0b chore(idempotency): default userIdResolver to cookie session (#118)
Drop the `resolveUserIdForIdempotency` helper that was duplicated across
three PWA write routes. `withIdempotency` now reads the userId from
`getSession()` by default; routes that authenticate via Bearer token can
still pass a custom resolver.

Net: −15 LOC across the route layer, +2 test cases for the new default.

Marc-André BombeckandClaude Opus 4.7 b9ade5b519 fix(api): address review findings — N+1, idempotency cache safety, device hijack guard
Three fixes from the 5-way review on PR #117:

1. Insights cards: replace per-medication N+1 query with single batched
   findMany + JS bucketing. For users with many active medications this
   collapses 10+ sequential round-trips into one.

2. Idempotency cache: only persist 2xx/3xx and validation 4xx responses.
   401/403/408/429/5xx are now skipped — a stale 401 (token expired
   mid-flight) or transient 5xx must not be replayed for 24h. Adds a
   defence-in-depth check that refuses to cache any body containing
   "hlk_" so a future caller wrapping an auth route in withIdempotency
   cannot leak a freshly-issued bearer token through the cache.

3. Devices: reject cross-user token re-registration with 409. Prior
   behaviour silently transferred ownership on findUnique-by-token,
   which would let anyone who learns/guesses an APNs token redirect
   another user's pushes. Audit-logs the denial with reason.

Tests adjusted: device-hijack test now expects 409, plus a new test
for same-user re-registration. 279/279 tests passing.

Marc-André BombeckandClaude Opus 4.7 9766cedea4 feat(api): generic Idempotency-Key support for safe POST retries
Introduces `withIdempotency()` in `src/lib/idempotency.ts` — wraps a
mutation handler so that a POST/PUT/PATCH/DELETE carrying an
`Idempotency-Key` header is replayed from the cached response instead of
running twice. Cache row is keyed by `(userId, key, method, path)` with
24h TTL; replays carry `X-Idempotent-Replay: true` so callers can
distinguish them.

Applied to the three mutation endpoints most exposed to client retries:
  • POST `/api/measurements`
  • POST `/api/mood-entries`
  • POST `/api/medications/[id]/intake`

Without the header: zero behaviour change. Existing clients that don't
send the header simply skip the cache lookup.
