POS now writes `succeeded`, validates session-terminal ownership, stores source/terminal/session/store/customer on the order, and correctly maps idempotent replay payment/item rows. Typecheck and POS tests 8/8 pass. Runtime sale and replay both HTTP 201 with the same order `0ea1004d-1fd5-41c6-be7c-c4910c88f481`.

-# F-177 — Add stale order notifications to admin header
+# F-179 — Fix POS sale Internal Server Error
 
-Create an admin-only stale-order endpoint and header bell. Notify when an order remains in `PENDING` or `SHIPPED` for at least 24 hours since its last state transition. Show badge count, dropdown details, elapsed time and direct links to each order. Refresh automatically and on demand.
+Cause: POS writes payment status `COMPLETED`, but database accepts lowercase lifecycle values such as `succeeded`. Repair payment persistence, idempotent replay, and POS order source/session/store/customer snapshots so completed sales are valid and reportable.
