⚠️ Potential issue | 🔴 Critical

🧩 Analysis chain

ALS context is limited to validation; make it request‐scoped for non‐TRPC routes.

runWithAlsSession(sessionId, () => ...) scopes ALS only around validation. Downstream handlers (e.g., /live, /webhook, /oauth, /misc, /ai) will miss ALS, so the Prisma session‐consistency extension can’t see sessionId during DB reads → potential read‐after‐write inconsistency outside TRPC.

Prefer entering ALS for the entire request after you derive sessionId:

  • If @openpanel/db can expose enterAlsSession(sessionId), call it here before validation and leave it set for the remainder of the request.
  • Otherwise, add a request‐level middleware that wraps route handling under als.run/enterWith.

I can provide a small helper and wire‐up if useful.

Run to confirm coverage (expect TRPC covered; verify non‐TRPC):

ALS context is limited to validation; extend it to request-scoped for non-TRPC routes.

The onRequest hook (lines 147-154) validates the session within runWithAlsSession(sessionId, ...) scope, but this context exits after validation completes. The non-TRPC routers registered at lines 191-196 (/live, /webhook, /oauth, /misc, /ai) and their controllers (which we found making DB calls in healthcheck.controller.ts, ai.controller.ts, webhook.controller.ts, oauth-callback.controller.tsx, export.controller.ts) execute outside this ALS context, creating risk of read-after-write inconsistency during database operations.

TRPC is properly covered by its own sessionScopeMiddleware (at packages/trpc/src/trpc.ts:155–169), but non-TRPC routes lack request-level ALS wrapping.

Recommend one of:

  • If @openpanel/db can expose enterAlsSession(sessionId), call it in the hook before validation and leave it set for the entire request lifecycle.
  • Otherwise, add a request-level middleware that wraps all downstream route handling under als.run() or als.enterWith().
🤖 Prompt for AI Agents 
In apps/api/src/index.ts around lines 147 to 154, the ALS is only set during
session validation and exits before non-TRPC routes run; fix by establishing
request-scoped ALS for the whole request: if @openpanel/db exposes
enterAlsSession(sessionId) call it before validation and leave it set for the
request lifecycle, otherwise add a request-level middleware (placed before
registering /live, /webhook, /oauth, /misc, /ai routes) that wraps downstream
handling in als.run() or als.enterWith() using the decoded sessionId so all
subsequent controllers execute inside the same ALS context.
