"""Direct tests for the ``handle_835`` handler (SP27 Task 5).
|
|
|
|
Locks the handler's contract independent of the scheduler lifecycle
|
|
so a regression in the scheduler wiring doesn't hide a regression
|
|
in the handler.
|
|
|
|
Note: the 835 handler is the largest of the four because the schema
|
|
covers per-claim remittances + CAS adjustments + validation. The
|
|
two-phase ingestion problem (batch row first, then a separate
|
|
``reconcile`` pass) is a known gap; atomic unification happens in
|
|
SP27 Task 10. For Task 5 we lock current behavior (no atomic).
