Three places where the copy promised more than the handler delivers. The hero's personal-baseline line rendered unconditionally while both its siblings in the same meta row gate on their own data. It claims the subtitle above it was drawn from the reader's own last 90 days, but with no briefing the subtitle is fixed fallback copy computed from nothing — so an account with no briefing at all was told its generic sentence rested on a personal baseline. Gate it on the briefing, like the rest of the row. The pulse sub-page promised a personalised Karvonen target band. Karvonen is not computed anywhere: the band comes from CDC/NCHS population percentiles by age and sex, and falls back to a fixed 60-100 for a reader with no age on file. The copy now says that in all six locales, and the fallback's own source label says it is a general adult range rather than a personal one, because that arm is the same band for everyone. Karvonen itself stays unimplemented; whether to build it is a product decision, not a copy fix. The Coach's `allTime` window returns 365 days, identical to `lastYear`, and it is the default. "year so far" was wrong too — a rolling 365 days is not year-to-date. Both labels now say what the reads do. The two options remain functionally identical and one of them should probably go, but removing a default is a product decision.
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__/.
