Client-rendered times fell back to the hardcoded display zone
(Europe/Berlin) because neither useFormatters() nor the legacy format.ts
helpers ever received users.timezone. A third localStorage mirror
(timezone-mirror.ts, following the time-format/date-format pattern)
carries the validated profile zone from /api/auth/me into both read
paths; the fallback chain is strictly profile → Europe/Berlin — never
the browser zone, so screen, PDF, and export cannot disagree.
makeFormatters validates its zone before Intl (a poison value falls back
instead of throwing inside every render).
Same pass, per the two-document audit: formatUpdatedLabel boundary and
clock now resolve one zone in every state (the undefined-tz browser hole
is closed); @db.Date calendar fields render UTC-pinned so profiles west
of UTC cannot shift a day; dose-history day headings and GLP-1 weekday
labels derive from the display zone; chart day/month labels are
encoding-derived and UTC-pinned (bucket math untouched, byte-identical
for Berlin profiles); the clinician share view renders in the patient's
timezone instead of the container's; Playwright pins Europe/Berlin.
Server day-key semantics, streak anchoring, insight cache keys, and
verbatim wall-clock strings are untouched by construction and pinned by
the new Auckland/New_York/Manila + DST test matrix.
One-shot prettier pass so the new format:check gate starts from a clean
baseline. Formatting only — no behaviour change. Generator-owned and
vendored artifacts stay untouched via .prettierignore.
A typed apiFetch wrapper owns the envelope unwrap, the ok-check and the
error read for every client call — two hundred call sites across the
app migrate onto it and a lint rule keeps raw api fetches out for good.
The legacy timezone helpers fold into the tz module and test fixtures
drop personal names.
The clock format followed the UI language with no way out — an English
interface forced AM/PM everywhere. A new profile preference (automatic,
24-hour, 12-hour) feeds every formatter through the shared locale
context, persists on the user row and rides the profile endpoints. The
insight pill list in settings gains the same eye toggle the overview
tiles have, so ordering and visibility live in one place; the page-side
'manage detail pages' block folds into a link there. Includes the
locale bundles for both features and the regenerated API contract.
Marc reported raw `insights.relativeHoursAgo` rendering verbatim across
medication cards, recent-achievements, admin sections, and the iOS
notification preview — anywhere `formatDateOrRelative` paints a
timestamp older than 60 s. The helper called `t("insights.relative
MinutesAgo", { count })` / `t("insights.relativeHoursAgo", { count })`
against a translation bundle that ships only the pluralised `*One` /
`*Other` variants; the i18n surface performs no auto-pluralisation so
the bare key bounced through `t()`'s identity fallback into the UI.
The fix mirrors the One/Other dispatch pattern that the v1.4.43 H6
sweep added to the canonical `src/lib/i18n/relative-time.ts:24-48`
helper. The format-twin in `src/lib/format.ts` was missed in that
sweep because the two helpers had drifted into byte-different siblings
since v1.4.20.
Audit confirmed the leak was isolated to these two keys: I cross-
checked every `t(…, { count })` call in the repo against
`messages/en.json`. The other 17 call sites (`insights.dayStreak`,
`medications.importDuplicatesSkipped`, `achievements.metricPercent`,
`passwordStrength.minLength`, `settings.integrationPill.*`,
`targets.*`, `admin.section.backups.uploadSuccess`,
`trendHints.remainingMany`, `dashboard.staleHint`, …) all use plain
non-pluralised keys that exist verbatim in the bundle.
Regression guard added to `format-date-or-relative.test.ts`: drives
every relative bucket through the helper, collects the `t()` keys it
emits, and asserts each one has a matching entry in `messages/en.json`.
Pre-fix this guard fails on the two bare keys; future twin-helper
divergence (e.g. someone adds a third date-formatting helper with a
copy-pasted body that lacks the pluralisation step) trips it before
it reaches prod.
Bundles v1.4.49.1's analytics rollup-tier delegation that the Coolify
auto-deploy never picked up.
Tests: 5269 unit + integration pass, lint clean, typecheck clean.
Eight touch-disjoint waves landed on develop before this release:
- W-INSIGHTS-HOT + W-RECONCILE-INSIGHTS — extract the timeout-stub
persist helper and wire all seven *-status routes through it, closing
the recurring ~14 s warm response the iOS client sees on dashboard
open once the AI provider has stalled once that day.
- W-DELETED-2 — close the remaining three soft-delete reader-tier gaps
(export bundle, gamification achievements, doctor-report aggregator)
with a five-route integration-test pin.
- W-ORG — types consolidation into src/types/analytics.ts and
src/types/backups.ts; prompt directory unification.
- W-FRONTEND-FACTORY — queryKey factory expansion + ESLint rule lift.
- W-IOS-COORD — POST /api/auth/check-user four-branch onboarding
discovery, identifier matched verbatim, per-IP rate-limited.
- W-SIMPLIFIER — today-intake projection helper extract; unused tx?
params dropped; 13 knip-flagged dead exports trimmed.
- W-PERF-OPS — v1.4.39 W-SUM legacy-NULL UNION discovery arm retired.
- W-PROCESS-DOCS — pg.Pool sizing operator doc; ESLint rule
formalisation; knip CI gate staged for v1.4.42 flip.
No migration, no env-var change, no API contract break for iOS v0.5.4.
The new check-user endpoint is an additive surface. AP-2 .p8 key is
installed; SB-5 time-sensitive APNs is live as of this deploy.
pnpm test --run green at 4732 passing / 1 skipped.
pnpm typecheck, pnpm lint, pnpm knip green.
* 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.
