Hiding a marker takes it out of the labs catalogue and the entry pickers, but the timeline still offered it among the lab values. The timeline now offers only markers that are not hidden. A hidden marker that was chosen before keeps drawing its line and stays in the menu as a ticked entry, named from that line, so it can be unticked, the way the entry form keeps a hidden marker that is already selected. Once unticked it is no longer offered.
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__/.
