The Personal Health Score weighted the 0.20 mood-stability pillar unconditionally — the fast-path read mood entries regardless of the account's module state, so a user who turned the mood module off was still scored (and silently penalised or rewarded) by a pillar hidden everywhere else in the product. The dashboard already blanks the mood tile and the coach snapshot unions mood out; the score ring and the insights card pillar list did not. Thread a default-on `moodEnabled` flag through the fast-path. When the caller resolves the mood module as disabled the helper skips the mood read entirely and leaves the series empty, so `moodStability` returns null and the existing proportional null-redistribution re-scales the surviving pillars to sum to 100. The analytics route resolves the module server-side and threads the flag; the insights card hides the Mood row via a new SSR-safe `useModuleEnabled` accessor so it never advertises a pillar the account turned off. Golden fixtures pin mood-on vs mood-off to different, correctly re-weighted scores and assert the disabled read is never issued. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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,app-settings-provider.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__/.
