Sweeps every surface that renders a date from before this year without a year suffix — illness episodes/flares/day-logs, lab and custom-metric charts, the mood chart family, medication titration/side-effects/dose- history/next-dose captions (incl. the Dec→Jan rollover), cycle predictions and history, the BBT chart, the intraday-pulse day-nav, the date-range filter chip, and the nutrient/compliance charts. Each now routes through dateShortSmart / dateWithWeekdaySmart (format-locale.ts) or the matching date-format.ts helper, which add the year only when it differs from the current one — mirroring the workout list's existing model instead of a bare "19.02." that reads as this year's. Also fixes two sites that bypassed the app's locale entirely: the trusted-devices expiry (bare toLocaleDateString, host locale) and the admin token-name timestamp (hard-coded de-DE + Europe/Berlin) now both render through the user's own locale, hour-cycle, and timezone preference.
src/components/
React components. The UI primitives are shadcn/ui (new-york style, zinc base) over Radix + Tailwind 4 + Lucide; everything above the primitives is feature-grouped by surface. Components are server components unless they need a hook, state, or browser API, in which case they open with "use client". Charts use Recharts 3 — replacing the chart library requires explicit approval.
Primitives and shell
ui/— shadcn/ui primitives (button, dialog, sheet, table, …). Generated by the shadcn CLI; keep edits minimal and on-style.layout/— the app shell: sidebar, topbar, bottom nav.providers.tsx,version-poller.tsx— top-level context providers and the self-healing stale-shell poller.i18n/— translation context + locale switcher.
Feature groups
insights/— insight status, assessment cards, Coach surface, advisor cards (the largest group).medications/— medication cards, the schedule wizard, intake timeline, detail history.settings/— the section components behind each settings page.measurements/,mood/,dashboard/— entry forms, lists, dashboard tiles.charts/— Recharts wrappers.monitoring/— Umami / GlitchTip client bootstrap.gamification/,targets/,comparison/,doctor-report/,clinician/,onboarding/,admin/— the remaining per-surface groups.
Conventions
Kebab-case filenames; React component exports stay PascalCase regardless. (A handful of PascalCase-filename outliers under medications/ + onboarding/ are pre-existing drift, noted in ../../CLAUDE.md.) Every t() call needs a matching key in messages/en.json — guarded by i18n-call-site-coverage.test.ts. Data reads go through TanStack Query with keys from @/lib/query-keys and unwrap (await res.json()).data. Tests live in __tests__/.
