10-baseline-probes

Proves the four decay signals (LIVENESS, VOLUME, FIELD_POPULATE, LAST_MATCH) can be computed from archives.json +alerts.json.

What was done

  • Lab brought up, logall_json enabled at runtime, /usr/bin/id added as monitored command (Docker victim can't run auditd)
  • purple-loop T1033 live run: DETECTED (score 100, 473 events)
  • Built reusable probe script at decay-planning/probes/probe.sh
