Slice 2 of phase 3 of #1095. A reading that stated a unit other than its marker's was refused. When the marker's analyte is known and the registry has the pair, the three write paths now convert it instead: POST /api/labs, the OCR commit and the document commit. The converted value is stored at full precision in the marker's unit, with what the report printed in the existing source_value and source_unit columns. The report's own reference window is in the printed unit, so it is converted with the value; otherwise the verdict would compare a converted value with an unconverted window. A pair the registry does not have is still refused as before (the 422 now says why), as is a marker whose analyte is unknown. The marker's key is filled the first time a reading needs it. The same scan committed again is still a duplicate: a converted row holds the number in the marker's unit, so the duplicate check also matches on what the report printed. Editing the value of a converted reading clears the conversion record, because the number is then the person's own. The lab result DTO and the OpenAPI schemas (labs and the OCR commit) carry converted, sourceValue and sourceUnit. Refs #1095
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__/.
