Token verification: jwtVerify now carries a closed asymmetric algorithm allowlist (RS256/PS256/ES256/EdDSA — an HMAC alg would let anyone with the client secret forge identities) and a 60 s clock tolerance for the usual self-host drift between IdP and app box. The JWKS fetch — jose's own, outside safeFetch by design — is disciplined instead by pinning the jwks_uri host to the configured issuer's host byte-exact and passing the same 15 s timeout safeFetch defaults to. requirePublicHost stays deliberately unused on this surface: LAN/Tailscale-only IdPs are a legitimate topology and the issuer is operator config, not user input. Discovery: the issuer comparison now tolerates exactly one trailing slash on either side (a recurring IdP/operator mismatch); token verification still matches the provider-sent issuer byte-exact. State cookie: the cookie is set under Path=/api/auth/oidc but was deleted without a path — RFC 6265 keys cookies by (name, domain, path), so the deletion never matched and the single-use blob survived its whole TTL. Every delete now repeats the exact path, via a shared constant. Also: the IdP error code recorded in the wide event is whitelisted against the closed OAuth error-code set (unknown values collapse to "other"); the status route drops an unreachable try/catch and a duplicated annotate; the passkey conditional-UI autofill stays unarmed under OIDC_ONLY (passkey login is a server-enforced dead end there); env-manifest gains the three optional OIDC_* tuning vars; the env example notes why the issuer should be HTTPS.
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.
