The response-timeout setting reached the briefing, the status notes and the Coach, which threaded it by hand. Document reads, document extraction, lab OCR and lab staging called the provider without a timeout, so every client fell back to its own 60 s literal and a slow self-hosted model was cut off however high the setting stood. The setting now rides on the provider instance. resolveProvider, resolveProviderChain and resolveProviderForTest stamp the record's aiResponseTimeoutSeconds on everything they return, and each wire client reads its ceiling through callTimeoutMs: the setting, else the surface's own timeoutMs, else 60 s. A call site no longer has to pass it, so a new one cannot forget it. The connection test runs under the same ceiling a read does. The Coach nudge tick and the reaction line keep their short ceilings (timeoutPolicy: "surface-ceiling"): the tick runs accounts one after another under a shared budget, the reaction line's claim lease is shorter than the largest setting, and both have deterministic copy that stands in. /api/auth/me publishes the effective value as ai.provider.responseTimeoutMs, so a client can size its own request timeout from it instead of guessing.

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__/.
