Deferred perf fixes from the campaign's verified perf-correctness audit,
correctness-first (each with an output-equivalence test):
- comprehensive-generate fan-out: replaced per-type 400d findMany+JS-average
with DB prisma.aggregate(_avg) over the exact half-open windows the JS
reducer used (current 30d, lastMonth (60d,30d], lastYear (395d,365d]), same
rounding + null-on-empty, pLimit(4). SLEEP_DURATION stays on the raw path
(per-night reconstruction dedup). Byte-equality test vs the old algorithm.
- boot-discovery: replaced Prisma in-memory distinct with DB SELECT DISTINCT
in the 4 backfill discovery scans + migration 0243 (7 additive
partial indexes matching each predicate). Integration test asserts identical
discovered set against real Postgres.
- ChatBubble wrapped in React.memo with a comparator (onRegenerate compared by
presence — the thread rebuilds it each render), so only the streaming bubble
re-renders per token.
- doctor-report mood read narrowed to {score, tags} (the only fields the
collector uses); the 730d main measurement read left as-is — a blind bound
would corrupt clinical stats (documented deferred follow-up).
Migration 0243 additive-only.
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__/.
