Denial lifecycle

A typical operating sequence is:

NEW
 ↓
IN_REVIEW
 ↓
APPROVED
 ↓
SUBMITTED
 ↓
OUTCOME_RECORDED

The repository also contains exception, recovery, intervention, and escalation workflows around this core path.

Transitions are validated in application code instead of being treated as arbitrary status changes.

Evidence and deadlines

Case work can carry evidence, deadline provenance, comments/timeline activity, and payer interaction history. Outcome history is stored as workflow data rather than as a prediction.
