Circuit-breaker pattern to avoid routing to unhealthy harnesses.\n\n## Current State\ndiscoverHarnesses() checks CLI availability at startup. No runtime health monitoring.\n\n## Target State\nContinuous harness health monitoring during runs. Error rate tracking per harness. Circuit-breaker pattern: mark harness unhealthy after N consecutive failures, retry after cooldown period.\n\n## Dependencies\n- [GAP-HADAPT-001](../harness-adaptation/GAP-HADAPT-001.md) -- routing foundation\n\n## Key Files\n| Component | Path |\n|-----------|------|\n| Harness discovery | `packages/sdk/src/harness/discovery.ts` |\n| Harness invoker | `packages/sdk/src/harness/invoker.ts` |\n\n## Recommendation\nPhase 3 implementation. Add health tracking to harness adapters. Implement circuit-breaker pattern. Integrate with routing engine.\n",
