- tests/test_simulator.py: 22 tests for determinism, SLO scoring, all
action types, termination logic, and observation helpers
- tests/test_grader.py: 5 tests for score bounds, partial credit,
determinism, and resolved bonus
- tests/test_propagation.py: 10 tests for queueing theory (Little's Law,
retry amplification) and circuit breaker state machine
- Fix: episodes no longer terminate as "resolved" when SLO=1.0 but
injected failures haven't been remediated (resource leaks, gradual
failures now properly degrade over time before resolution)
All 37 tests pass.
