A slot-less "taken now" write (no client scheduledFor) defaulted its instant to now/takenAt and snapped across the wide ±halfGap window onto the nearest scheduled slot. For a 07:00 / 19:00 med a midday write captured the 07:00 morning slot and stamped it taken — a phantom morning dose. The web fix only threaded the displayed slot on the card; any client posting takenAt-only (iOS bulk/sync) still tripped it server-side. Thread an instantIsExplicit flag through resolveSlotInstantForWrite into the canonical resolver. An explicit scheduledFor keeps the full ±halfGap snap unchanged. A defaulted-now write snaps only inside the tight dose-grace window and otherwise resolves to null (PRN), so it records a standalone taken-now row instead of back-filling a far slot. Both intake call sites pass scheduledFor !== undefined; takenAt alone is not explicit. Add resolver unit coverage for midday defaulted-now writes (07:00/19:00 → null at 11:00/12:00/13:00, explicit 07:00 still snaps) and a DB-backed regression that a takenAt-only midday write leaves the 07:00 slot untaken.

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.ts; outbound HTTP goes through src/lib/safe-fetch.ts.
