15-scenario-a-source-death (supersedes blocked #55)

Proved the probes catch silent source death when Sysmon channel collection is disabled — agent stays Active but EID 1 telemetry collapses.

Results

Probe BEFORE (healthy) AFTER (dead)
LIVENESS active inactive (no events in window)
VOLUME 64 0 ← caught it
FIELD_POPULATE 100% N/A
LAST_MATCH 60137 @ 07:09 60137 @ 07:14 (frozen)

Key finding

Agent-liveness monitoring ALONE would miss this. Agent 002 was Active throughout. VOLUME collapse to 0 is the definitive signal.

Revert

Sysmon block restored, agent restarted, alerts resumed, lab healthy.
