Branch periodic scan workflow

The workflow proceeds from prevention through assurance to investigation and recovery. Configure coverage first — a scan that was never configured to run cannot be triaged.

Workflow procedure

1. Configure repository scan coverage.
2. Assess scan coverage and health across the portfolio.
3. Investigate a scan result, prioritize the issues, and remediate.
4. Triage a scan that failed or completed partially.
5. Diagnose a scan failure through data source instance health.
