A full rollup backfill that failed on every boot showed only on the admin page's card of failing background jobs. From the account's side the only symptom was empty dashboard cards, and nothing pointed the operator at the card (#1298). A new hourly evaluation reads the newest terminal runs of every queue whose failure has no account-facing surface (the system audience in subsystem-surface.ts) from pg-boss's own ledger. A failed run adds its attempts, retries included, and the first successful run ends the streak. Three failed attempts in a row send every admin a SYSTEM_ALERT once, a reminder at most once a day while the queue keeps failing, and one notice when it runs successfully again: the decision the backup health notices use, with the same compare-and-set claim, so two workers never send a notice twice. The memory is one row per announced queue in system_job_alert_notices (migration 0490). The notice names the queue, the streak and the last error, and opens the admin status page.
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.
