* fix(i18n,ux): package A — missing keys, chart labels, query invalidation, admin error UX
Addresses bugs surfaced in issues #73 and #74 plus drift found during audit.
- i18n: add 21 missing translation keys (targets.* namespace was only
partially populated after the English-first migration; common.reset and
settings.configured were referenced but absent), plus common helpers
(copy, copyDetails, retry, reportIssue) and admin.settingsSaveError.
- charts: rename points7Label/30Label/90Label from cryptic "7P/30P/90P"
to "7 pts / 30 pts / 90 pts" in EN and "7 Pkt / 30 Pkt / 90 Pkt" in DE.
- queries: add src/lib/query-keys.ts as a single source of truth with
measurement/mood/medication-dependent key sets. Wire them into
measurement-form/list, mood-form/list, medication-form/card,
intake-history-list, intake-timeline, medications page, and Withings
sync in settings. Fixes dashboard not auto-refreshing after adding a
measurement (old code only invalidated ["measurements"], not
["analytics"] / ["insights"] / ["insights","targets"]).
- admin: useUpdateSettings + updateUser mutations now surface real error
messages via sonner toasts and invoke getApiErrorMessage() so saves
fail loudly instead of silently. Success also gets a toast.

* refactor(i18n): package B — locale-aware formatters throughout
Removes the hard-coded de-DE locale that lingered from the German-first era
and makes every number, date, and time locale-aware. English stays the
default per user preference; German remains selectable.
New:
- src/lib/format-locale.ts exposes makeFormatters(locale) + a cached
Europe/Berlin timezone. Covers number, integer, percent, date, dateShort,
dateTime, time, dateWithWeekday, monthShort. Also exports
parseLocaleFromAcceptLanguage() for server code.
- useFormatters() hook in @/lib/i18n/context resolves from the active
locale, memoized per render.
Migrated (all Intl.NumberFormat("de-DE") / toLocaleString("de-DE") /
Intl.DateTimeFormat("de-DE") call sites):
- src/app/page.tsx (dashboard)
- src/app/insights/page.tsx
- src/app/admin/page.tsx
- src/app/settings/page.tsx (Withings last-sync, doctor-report caller)
- src/components/charts/trend-card.tsx (+ i18n "7d"/"30d" short labels)
- src/components/charts/health-chart.tsx
- src/components/medications/medication-card.tsx
- src/components/medications/medication-form.tsx
- src/components/measurements/measurement-list.tsx
- src/components/mood/mood-list.tsx
- src/components/insights/insight-status-card.tsx (also removed 5 German
hard-coded strings with TODO: i18n markers — now translated)
- src/components/insights/insight-advisor-card.tsx (same — 10+ strings)
Server: reminder-check / reminder-worker / umami-test switched from
"de-DE" to neutral en-GB/en-US where the string is machine-compared rather
than user-facing. Bug-report GitHub issue titles use ISO-8601 UTC now —
the repo is English-speaking.
Next.js metadata:
- OpenGraph locale from "de_DE" → "en_US" with "de_DE" as
alternateLocale.
- Root layout now reads healthlog-locale cookie (falls back to
Accept-Language) and sets <html lang> server-side, avoiding an
EN-flashes-then-DE hydration gap and fixing SEO/a11y.
- I18nProvider mirrors locale to a 1-year SameSite=Lax cookie so the next
SSR pass is correct.
Doctor-report PDF:
- generateDoctorReportPDF(data, { t, locale }) now accepts injected
translator + locale. All section titles, column headers, BMI / BP
classifications, mood labels, and the footer disclaimer are
i18n-driven. File name slug switches between gesundheitsbericht / health-report.
- 40+ new doctorReport.* keys in EN + DE.

* feat(ux): package C — typed passkey errors, bug-report gating, error boundary
Addresses issue #73 points 1, 5, 6 and lays groundwork for copy-paste
error reporting requested during review.
Passkey registration / login (#73.1):
- src/lib/passkey-errors.ts maps DOMException.name + SimpleWebAuthn code
to specific i18n keys instead of swallowing every failure as
"cancelled". Distinguishes NotAllowed/InvalidState/NotSupported/
Security/Abort errors and falls back to a diagnostic message.
- settings passkey + login passkey flows both use describePasskeyError
now, so origin mismatches and previous-registration collisions show
actionable copy.
- 5 new passkey.* i18n keys in EN + DE.
Bug report (#73.5):
- New GET /api/bugreport/status reports {configured, hasToken, hasRepo,
isAdmin}.
- /bugreport page now queries status first. When not configured it shows
a notice (different copy for admins vs. regular users) with a direct
link to the admin panel. Form is hidden, not silently broken.
- When POST /api/bugreport can't create issues it returns 503 instead
of 500 with the same user-facing message.
- 4 new bugreport.* i18n keys.
Global error UX:
- src/components/error-details.tsx — reusable panel with retry + copy
diagnostics (message, digest, stack (trimmed), URL, user-agent,
request-id, locale, timestamp) + report-issue link. Clipboard fallback
prompt covers insecure-context cases.
- src/app/error.tsx uses it.
- src/app/global-error.tsx is provider-free (no i18n dependency) since
it replaces the root layout on catastrophic failures — hardcoded
English + Dracula palette so it still looks like HealthLog.
- 2 new errorBoundary.* keys and 4 common.* keys (copy, copyDetails,
retry, reportIssue).

* refactor(query-keys): collapse repeated invalidation blocks into invalidateKeys helper
Eleven mutation handlers repeated `Promise.all(keys.map(k => invalidate({queryKey: k})))`
verbatim. Adds `invalidateKeys(qc, keys)` to the existing query-keys factory and
adopts it everywhere, including replacing the local `invalidateMedicationRelated`
helper that medication-form.tsx had grown. Also fixes the import-sandwich that
helper introduced.

* refactor: small simplifications in i18n/UX changes
- passkey-errors: drop the typeof-name dance now that error.name is already string after the instanceof Error narrow
- doctor-report-pdf: replace nested gender ternary with a small lookup map; clarify unitFor's null-as-translation-marker convention
- dashboard page: route the analytics queries through the new queryKeys factory so future invalidation stays in one place
- health-chart: add missing fmt dependency to trendInfo useMemo (introduced when formatSigned was switched to the locale-aware formatter)

* fix(ai): capture upstream response body in OpenAI errors
A production insights burst at 12:19 UTC failed with "OpenAI request
failed (500)". The 500 was the upstream OpenAI HTTP status (confirmed
via logs), but we had no way to tell from logs whether it was an
OpenAI incident, a model-not-found, or a response_format rejection
because the response body was thrown away.
Now the error message includes the first 500 chars of the response body
and structured fields (httpStatus, upstream, model) that Wide Event
logging can attach. No behavior change for the happy path.

* fix(review): address code-review + security findings
Review round produced five real issues — fix them all, plus three nits
that were cheap enough to bundle.
Must-fix:
- security: error-details.tsx + global-error.tsx were copying
window.location.href into the clipboard, which on OAuth callback
routes (/api/withings/*, password reset) would leak code/state
tokens into GitHub issues. Strip to pathname + searchParamCount.
- fe: query-keys.invalidateKeys now uses Promise.allSettled, so a
transient invalidate failure doesn't abort the chain and no
unhandled rejection leaks from void invalidateKeys(...) call sites.
- fe: resolveInitialLocale in app/layout.tsx wraps cookies()/headers()
in try/catch — a dynamic-server error in the root layout now
degrades to the "en" default instead of crashing into global-error.
- be: reminder-worker + reminder-check parseTimeToMinutes normalize
"24:00" → "00:00" (some ICU builds emit that for midnight under
en-GB). Prevents a 1440-minute comparison against schedule windows.
- security: openai-client error body excerpt redacts sk-* / Bearer
tokens before logging, and moves the excerpt off Error.message into
a structured field (bodyExcerpt) so log transports can filter it.
- i18n: /api/withings/connect German error message → English.
- i18n: /insights/page.tsx hardcoded "Fehler beim Laden" → t(...)
Hardening:
- /api/bugreport/status collapses to {configured, isAdmin} and adds
a 30/min rate limit per user. Client interface updated.
- i18n/context.tsx: I18nProvider's initializer now reads the cookie
(matches SSR) before falling back to localStorage or browser
detection — eliminates the locale-flash hydration class.
- format.ts legacy helpers also read cookie first, matching SSR.
Tests:
- new src/lib/__tests__/format-locale.test.ts — 9 cases covering
makeFormatters, parseLocaleFromAcceptLanguage, resolveIntlLocale
- new passkey-errors.test.ts — 8 cases covering every DOMException
name and SimpleWebAuthn code we map
- new query-keys.test.ts — bundles + invalidateKeys allSettled
semantics (incl. partial-failure test)
118 → 142 tests. All pass.

Replace direct OpenAI API calls with resolveProvider() in all insight
generators (general, blood-pressure, weight, pulse, bmi, medication-
compliance, mood). Each generator now uses domain-specific prompts from
@/lib/ai/prompts/ and the AIProvider.generateCompletion() interface.
hasKey -> hasProvider in return signatures and all UI consumers.
Remove openaiKeyEncrypted references from data reset routes.

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.
HealthLog — personal health-tracking PWA with weight, blood pressure,
pulse, mood tracking, medication compliance, Withings integration,
doctor report PDF export, and Dracula-themed UI.
