Witness Observer

Per-rig observer that monitors polecat health and reports anomalies. The witness is the PMU (Performance Monitoring Unit) of the Gastown chipset -- it watches execution units for stalls, detects degraded performance, and raises alerts without interfering with computation. The witness is strictly read-only with respect to agent work. It observes and reports; it never modifies.

Activation Triggers

This skill activates when:

• The agent is assigned to monitor a rig's worker agents
• Multiple polecats are running and health monitoring is needed
• Stall detection is required for long-running work items
• The mayor needs a supervisory agent to watch active polecats

Core Capabilities

Patrol Loop

The witness runs a periodic patrol that checks all active agents in its rig for health indicators.
