A restored account got a Coach that had never spoken to it. The conversations, every turn in them, and the record of which vault documents a thread was grounded in were all classified as backed up and travelled with nothing. The register's own entry for the messages called them the largest volume of free text an account owns after its documents. The three travel together because two of them mean nothing alone: a turn without its thread has nowhere to hang, and an attachment names a pairing rather than a thing. documentScoped is the field that makes this more than lost history. It is a permanent fence — set when a conversation is created through the fenced endpoint or gets its first document, and lowered by no code path anywhere, not by detaching every document and not by deleting one. A restore that let it default to false would hand the tool loop back to precisely the conversations the fence exists to keep away from it, and nothing in the interface would look wrong afterwards. So it is carried verbatim, restored verbatim, and asserted per thread rather than in aggregate: a restore that wrote false everywhere would still return both threads and every turn and satisfy every count. Prose follows the contract the rest of the payload already uses. A disaster-recovery file carries the stored ciphertext; a portable file carries the text, because a portable export exists to be readable by the person who owns it, exactly as it already decrypts medication notes, mood notes and document summaries. A single row under a key the instance no longer holds is named rather than thrown, so one unreadable turn cannot cost someone the rest of the transcript. Ids ride in both modes, as the reminders do, so an attachment resolves and the facts, plans and reminders still owed have something real to point at. The restore runs after the documents for the same reason, and an attachment naming a document the file does not carry is dropped and reported instead of failing the whole file over one link. Verified by breaking it: forcing documentScoped to false on the way back fails the round trip on that field by name.
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.
