 Baseline fingerprints are stable across line shifts, so moving existing code up or down does not resurface already-recorded debt — only genuinely new issues are reported.

Each maps to the matching `scan` flag. `write-baseline` and `baseline` are mutually exclusive. With `fail-on`, a qualifying issue fails the job (gating the merge); `if: always()` still uploads the SARIF so annotations appear even on a failing run.
