Marc-André Bombeck 0f6d668df1 fix(workouts): match cross-source duplicates by a start window, not a clock slot
Two copies of one session were collapsed only when both starts fell in the
same fixed five-minute clock slot, so a pair thirty seconds apart that
straddled a slot boundary (08:04:50 and 08:05:20) stayed as two workouts in
the list, the batch write, the calendar, strain and the Coach.

Workouts of one user and sport are now clustered by start time: a workout
joins the open cluster while it starts less than five minutes after the
cluster's first start. Wherever no pair within five minutes straddles a slot
boundary the clusters are exactly the old slots, which a parity test checks
against the previous picker on thousands of generated inputs, strain impulses
included. A property test shows any offset under five minutes now collapses,
five minutes or more never does, and a uniform shift of every start keeps the
picked set.

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 renamed middleware). 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 in apiHandler. See app/README.md.
  • lib/ — the server/runtime toolkit: apiHandler, auth, crypto, rollups, AI, notifications, pg-boss jobs, integrations, rate limiting. See lib/README.md.
  • components/ — React components (shadcn/ui new-york, kebab-case files). See components/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 by prisma 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.
