Add Financial-Guardrail & Telemetry Harness with Arize Phoenix#31
Merged
Conversation
Wraps Bedrock AgentCore execution to audit token I/O at every discrete
reasoning step, acting as a financial circuit breaker that automatically
halts agents exceeding session budgets or stuck in repetitive loops.
New modules:
- src/factor/harness/ — budget tracker, loop detector, circuit breaker,
Phoenix OTLP telemetry, and GuardedBedrockModel proxy
- docker-compose.yml — self-hosted Arize Phoenix (UI :6006, OTLP :4317)
- tests/test_harness.py — 25 tests covering all harness components
Wiring:
- All 5 agent creation functions accept optional circuit breaker
- SSE stream emits guardrail_halt events on budget/loop violations
- New endpoints: /api/v1/sessions/{id}/budget, /api/v1/guardrail/status
- Config: phoenix_*, guardrail_* settings with Sonnet pricing defaults
