The saved Coach window only seeded the snapshot and each tool's default. A tool could still read back to all time, the availability probe reported counts and means for history outside the window, and several blocks read fixed windows of their own (labs 12 months, correlations 180 days, the coarse tail, the all-time extremes) whatever the setting said. coachPrefs.defaultWindow is now enforced as a limit through one module, history-reach.ts: the turn context clamps the client window, the snapshot clamps its window and gives every fixed-window block either the shorter window or, when the block's own window cannot fit, leaves it out. Every retrieval tool clamps its window, an earlier period or a stored table that reaches past the limit answers outside_reach, and the probe reads only inside the limit and names older history as outside_reach without any figure. Follow-up chips that would read past the limit are not offered. The default (allTime) is no limit and reads as before. MCP clients pass no limit and keep their own window arguments. Adds the twelve-month option, rewrites the picker text to state what is read with the numbers the readers use, shows the same options in the managed-profile settings, counts cluster members with a singular, and drops the opacity on switched-off rows that put their text below WCAG AA.
src/
Application source. HealthLog is a Next.js 16 App Router project (output: "standalone", React 19, TypeScript strict). The path alias @/* resolves to this directory. Everything a request touches lives under here; the layout below follows the request flow rather than alphabetical order.
Request flow
client → src/proxy.ts → src/app/<route>/route.ts → src/lib/api-handler.ts → handler body → src/lib/api-response.ts → client
proxy.ts— the HTTP edge (Next.js 16's renamedmiddleware). Public-path allowlist, demo-mode mutation block, server-side onboarding redirect, worker-only refusal,x-request-id+ CSP nonce generation, every security header.app/— App Router pages (RSC by default) and API routes. Every API route wraps its handler inapiHandler. Seeapp/README.md.lib/— the server/runtime toolkit:apiHandler, auth, crypto, rollups, AI, notifications, pg-boss jobs, integrations, rate limiting. Seelib/README.md.components/— React components (shadcn/ui new-york, kebab-case files). Seecomponents/README.md.
Other directories
hooks/— shared React hooks (use-prefix, kebab-case).types/— shared TypeScript declarations.generated/prisma/— the generated Prisma client (do not edit; regenerated byprisma generate). Imported as@/generated/prisma.instrumentation.ts— Next.js startup hook; boots the pg-boss worker registry and boot-time backfill queues.__tests__/— cross-cutting unit tests; most tests live in__tests__/folders next to the code they cover.
Conventions
See ../CLAUDE.md for the full set. The load-bearing ones: RSC by default ("use client" only when a hook/state/browser API needs it); every API route wraps apiHandler and parses its body with Zod safeParse; userId is always narrowed from session or Bearer, never accepted as a body field; TanStack Query keys come only from src/lib/query-keys/; outbound HTTP goes through src/lib/safe-fetch.ts.
