GAP-HADAPT-005: Harness Health Monitoring and Circuit Breaker

Field	Value
Category	harness-adaptation
Priority	Medium
Effort	M
Status	Missing

Description

Monitor harness availability and error rates. Circuit-breaker pattern to avoid routing to unhealthy harnesses.

Current State

discoverHarnesses() checks CLI availability at startup. No runtime health monitoring.

Target State

Continuous harness health monitoring during runs. Error rate tracking per harness. Circuit-breaker pattern: mark harness unhealthy after N consecutive failures, retry after cooldown period.

Dependencies

GAP-HADAPT-001 -- routing foundation

Key Files

Component	Path
Harness discovery	`packages/sdk/src/harness/discovery.ts`
Harness invoker	`packages/sdk/src/harness/invoker.ts`

Recommendation

Phase 3 implementation. Add health tracking to harness adapters. Implement circuit-breaker pattern. Integrate with routing engine.
