Marc-André Bombeck 70353882eb fix(security): close moodLog SSRF + central error redaction; fix citation drift (#148)
The v1.4.1 audit pass turned up one CRITICAL, two HIGH, and four
medical-citation drift findings. This commit addresses everything
that's safe to land in a hardening release; deeper architectural
fixes (idempotency-race transactional rewrite, encryption-key
fallback gate, refresh-token reuse-detection serialisation, moodLog
secret HMAC lookup column) are tracked for v1.4.2 in
docs/ops/v141-followup-issues.md.

Security
--------

CRITICAL — moodLog SSRF
  src/lib/validations/moodlog.ts now refines the credentials URL
  with isPublicUrl() so an authenticated user cannot store
  http://169.254.169.254/ (cloud metadata) or RFC1918 hosts.
  src/lib/moodlog/sync.ts re-checks isPublicUrl(baseUrl) at the
  fetch site (so legacy rows stored before the credential guard are
  also refused) and switches to redirect: "manual" + 3xx → fail so a
  public host cannot 302 the request to an internal target with the
  user's apiKey on the redirect hop. New unit test
  src/lib/validations/__tests__/moodlog.test.ts asserts the guard
  rejects 169.254.x.x, 10.x, 172.16.x.x, 192.168.x.x, 127.0.0.1, and
  localhost.

HIGH — error-message secret leakage
  New src/lib/logging/redact.ts redacts Bearer tokens (incl. our
  hlk_/hlr_), Telegram bot URLs (bot<digits>:<token>), and
  query-string secrets (?secret=, ?code=, ?token=, ?api_key=). The
  redactor is called from WideEventBuilder.setError() — every error
  reaching Loki is scrubbed once, centrally — and from the
  reportToGlitchtip() call in api-handler.ts so the Glitchtip
  incident UI is also protected. New unit suite covers the four
  patterns plus over-redaction (Bearer's \\S+ greedily consumes
  anything up to the next whitespace, which is the safer side of
  the trade-off).

Truthfulness — citation drift fixes (audit found 0 hallucinations,
4 drift items)
  - messages/{en,de}.json bpClassificationTitle and avg30dEsc:
    "ESC/ESH 2018" → "ESH 2023". User-visible on the dashboard and
    doctor-report PDF. The numeric thresholds are unchanged from
    2018; the 2023 update is ESH-only since ESC withdrew from
    joint authoring.
  - src/lib/analytics/classifications.ts: section header,
    getBpTargetsByAge() docblock, and inline comment updated to
    cite ESH 2023 with the same "numerically unchanged" caveat.
  - src/app/api/insights/targets/route.ts:375: source label "WHO"
    → "Saint-Maurice JAMA 2020". The AI-prompt anti-pattern guard
    explicitly forbids citing WHO for a step number; this surface
    was the last "WHO" mislabel in the codebase.
  - Saint-Maurice "mortality plateau 8000-12000" attribution
    softened to "continued dose-response benefit through ~12,000
    steps/day, not a plateau" in src/lib/medical-citations.ts,
    src/lib/analytics/effective-range.ts,
    src/lib/analytics/classifications.ts, and both AI prompts. The
    original JAMA 2020 paper shows continuing benefit (HR 0.49 at
    8k vs 4k, HR 0.35 at 12k); the plateau-shaped finding belongs
    to Paluch 2022 Lancet PH (PMID 35247352), not Saint-Maurice.

Marc-André BombeckandMarc-André Bombeck 8adeb59396 v1.4 medical-safety: protect against silent DBP hypotension, align BP & step citations, ACE body-fat consolidation (#123)
* fix(medical): protect against silent DBP hypotension and align BP citations

Three correctness issues that the v1.3.3 ecosystem audit surfaced and
that we deferred until the v1.4 cycle:

1. **Diastolic blood-pressure orange band reached 60 mmHg.** With the
   default age-based targets (DBP 70-79), the lower orange wing was
   computed as `diaLow - 10 = 60`, putting a sustained reading of
   60 mmHg into "mildly low" territory — visually a yellow tile, not a
   red one. 60 mmHg is widely treated as a hypotension / perfusion-risk
   threshold (general-adult <90/60 from AHA/NIH; J-curve evidence in
   ONTARGET / TRANSCEND for treated hypertensives; ESH 2023's explicit
   caution against treating below 70 in the elderly). The orange floor
   is now clamped at 65 mmHg, so a reading of 60 lands in red. The
   user-override path stays untouched and is already audit-logged.

2. **"ESC/ESH 2023" doesn't exist as a joint guideline.** ESC withdrew
   from the 2023 authoring; the 2023 hypertension document is ESH-only.
   The codebase had a mix of "ESC/ESH 2018" (analytics) and
   "ESC/ESH 2023" (AI prompts). Both are wrong in different directions.
   Every site (`bp-targets.ts`, `targets/route.ts`,
   `ai/prompts/blood-pressure.ts`, `ai/prompts/base-system.ts`) now
   cites "ESH 2023" with the published source URL. Target bands are
   unchanged 2018 → 2023 — only the citation moves.

3. **"WHO ≥ 8 000 steps/day" was a recurring hallucination.** WHO's
   2020 Physical Activity guidelines publish minutes per week, not a
   step quota. The cohort study HealthLog actually relies on is
   Saint-Maurice et al., JAMA 2020 (mortality plateau 8 000–12 000
   steps). The v1.3.3 fix landed in `effective-range.ts` but four AI
   prompt strings (`base-system.ts` DE+EN, `general-status.ts` DE+EN)
   carried the old wording forward. Same fix shape: cite Saint-Maurice
   for the step number and add an explicit "WHO does not publish a
   step quota" note so the model doesn't regress. Sleep target moves
   from "ESC" to AASM 2015 in the same surfaces — ESC publishes no
   adult sleep duration guideline.

Adds `src/lib/medical-citations.ts` as the new single source of truth
for cited guidelines (id, name, year, url, caveat). v1.4 surfaces will
import these constants instead of duplicating strings, and the new
`medical-citations.test.ts` drift-test asserts that every entry has a
non-empty url + caveat, that ids are unique, and that the WHO-as-step-
source hallucination cannot reappear as a constant.

Tests: 358 → 363 (5 new for the master citations list). Typecheck and
existing analytics tests pass. No clinical numbers changed beyond the
DBP orange-floor clamp.

* fix(medical): consolidate body-fat ACE bands and document bedtime-glucose source

Two related medical-truthfulness issues from the v1.3.3 ecosystem audit.

**Body-fat classification: ACE bands corrected.** v1.3.3's classifier
used `essential = 6 (M) / 14 (F)` as the *floor* of the "Essential"
category, which is actually ACE's *Athletes* lower bound. Anything
below was lumped under "Essential" — including readings (e.g. 1% male)
that are clinically concerning, not just "athletically extreme". The
classifier now mirrors the ACE table precisely:

- Below essential (M <2 / F <10): danger.
- Essential (M 2–5 / F 10–13): warning.
- Athletic (M 6–13 / F 14–20): normal.
- Fitness (M 14–17 / F 21–24): normal.
- Acceptable (M 18–24 / F 25–31): warning.
- Obese (M ≥25 / F ≥32): danger.

**Three-way drift in body-fat target ranges consolidated.** v1.3.3 had
three sites with three different green-band numbers:

- `value-bands.ts:118-120` returned M{10,20} / F{18,28}.
- `app/api/insights/targets/route.ts:336-338` hardcoded M{14,24} /
  F{21,31} with `source: "ACE"`.
- `classifications.ts:155-205` used a third overlapping set of
  thresholds for the band labels.

ACE fitness + acceptable (M 14–24 / F 21–31) is the realistic healthy
band for a non-athlete adult and is now the single source in
`getBodyFatTargetRange`. Targets route and chart value-bands import the
helper instead of duplicating the numbers.

**Bedtime glucose citation softened.** ADA Standards of Care 2024 §6
publishes pre-prandial 80–130 and post-prandial <180; the document does
NOT publish an adult bedtime target. The 90–150 mg/dL band HealthLog
ships is reasonable advice (within the daytime pre-prandial range,
slightly raised floor to avoid nocturnal hypoglycaemia) but it's not
ADA-published. The inline comment in `effective-range.ts` now states
the absence of an adult guideline explicitly and cites ISPAD 2022
(pediatric T1D, 80–140) as the closest comparator. Numbers unchanged.

Tests: 363 → 369 (6 new for the ACE bands). Existing assertions
unchanged.

* fix(medical): align step-range target with the effective-range source

`getStepsRange()` in classifications.ts returned `{7 000, 10 000}`
while `effective-range.ts` (the canonical resolver behind
`getEffectiveRange`) returned `{8 000, 15 000}`. The two surfaces
showed different "green" bands to the same user — `/api/insights/
targets` used the lower pair, the dashboard chart-bands used the
upper pair.

Aligns both on the upper pair, anchored on Saint-Maurice et al. JAMA
2020 (mortality plateau 8 000–12 000 steps/day). Adds the citation
header to the steps section so the next audit pass can verify in
place. WHO is explicitly called out as NOT a source for a step quota
(only an activity-time guideline).

The classifier function `classifySteps` is unchanged — its 3 / 5 / 7.5
/ 10 k bands match Tudor-Locke 2004 pedometer indices and are kept
distinct from the two-number "target range" helper.

Tests stay at 369/369.

Marc-André Bombeck 0c0c345e82 i18n: migrate from German-first to English-first default locale
Switch defaultLocale from "de" to "en" and make English the code-level
language throughout. All ~145 hardcoded German strings translated:

- API error messages (52 routes) now return English
- Zod validation messages in English
- Classification/analytics functions return English categories
- Notification type labels in English
- Component strings use i18n t() calls (heatmap, mood chart,
  medication form, intake history, password strength, insights card)
- ~50 new i18n keys in both de.json and en.json

Route migration:
- /stimmung → /mood, /zielwerte → /targets (new pages)
- 301 redirects in proxy.ts for legacy URLs
- Sidebar + bottom nav updated

Bump version to 1.0.1.
