Single-account escalation
Low confidence
For NORTHWIND-12, POST /auth/login is consistently returning 404 while POST /auth/verify is returning 200, indicating the login route is missing/misrouted and likely causing the reported post-login verification failures.

What this means
The recurring 404s on POST /auth/login suggest the login route was removed or not registered for this tenant, so users never establish a session; subsequent POST /auth/verify calls then behave inconsistently relative to the customer’s environment (they report a KeyError/500), which aligns with verify running without expected session context. Restoring a POST /auth/login handler (or aliasing it to the current login handler) should normalize the flow and stop the post-login verification failures.

Recommended fix
Code change
Reintroduce/alias the POST /auth/login route to the existing login handler so clients calling /auth/login receive a 200 and session establishment instead of 404.
Change required:
- In the web routing module, register a POST "/auth/login" endpoint that forwards to the existing login handler (currently used by other auth paths). Keep response schema identical to the canonical login path.
Example (FastAPI-style) change:
- Add:
@router.post("/auth/login")
async def login_alias(request: Request):
return await login_handler(request)
- Where login_handler is the existing function servicing the canonical login route. Ensure any session/cookie issuance mirrors the canonical path.
After deploying, verify that POST /auth/login returns 200 for NORTHWIND-12 and that subsequent POST /auth/verify continues to return 200.

Customer reply
Thanks for the report. From our logs for NORTHWIND-12, we’re seeing POST /auth/login returning 404s while POST /auth/verify is returning 200. That 404 on the login step would prevent session establishment and can cause the follow-up verify to fail on your side. We’re preparing a code fix to restore the POST /auth/login route so your clients no longer hit 404 there. Once deployed, /auth/login should succeed and /auth/verify should continue to return 200. Could you confirm the timeframe you observed the failures and whether user u_a1b2c3d4 was calling POST /auth/login before /auth/verify? We’ll update you as soon as the fix is live.
Internal note
Evidence shows repeated 404s on POST /auth/login for NORTHWIND-12 (e1, e2, e7) while /auth/verify returns 200 (e4, e9). No 500s in our logs. Likely the login route was removed/renamed, and their client is still calling /auth/login. Plan: re-add/alias POST /auth/login to the current login handler so sessions are established normally. After deploy, validate by issuing POST /auth/login and then POST /auth/verify for NORTHWIND-12; both should be 200.
Engineering handoff
Issue: For tenant NORTHWIND-12, POST /auth/login returns 404 while POST /auth/verify returns 200. Their clients likely still call /auth/login; missing route prevents session creation and leads to verification failures on their side.
Requested change:
- Restore/alias POST /auth/login to the existing login handler so clients receive a 200 and normal session issuance.
Implementation details:
- File: services/bindu_bazaar/bindu/web/routes/auth.py (around router registrations)
- Add route:
@router.post("/auth/login")
async def login_alias(request: Request):
return await login_handler(request)
- Ensure login_alias uses the same session/cookie issuance path and response model as the canonical login route. No behavior differences.
Post-change validation:
- For account_id=NORTHWIND-12, issue POST /auth/login and confirm http_status=200, then POST /auth/verify returns 200. Monitor logs for 15 minutes.
Evidence: e1, e2, e7 show 404s on /auth/login; e4, e9 show 200s on /auth/verify.
Risk: Low; route alias only. Rollback by reverting the route addition.

Verdict — Single-account escalation. Only this account is affected; the evidence points to a specific error pattern.
Confidence — Low. The checks barely cleared the bar. Treat this as a lead to follow, not an answer.
Who fixes it — Code change. This needs engineering: the cause is in shipped code.
