Circuit breaker trip and recovery (validates 3 state transitions) 2. Bulkhead saturation and graceful rejection 3. Resilient adapter end-to-end (CB + bulkhead + timeout compose) 4. Retry backoff and context cancellation 5. Half-open single-flight validation Release Gates (release_gates_test.go) - validate SLOs: 1. Fail-fast latency <1ms when circuit is open 2. Bulkhead isolation (saturated compute doesn't affect network) 3. Circuit recovery within resetTimeout window 4. Retry idempotency (exactly MaxAttempts executions) 5.

But the VPC deletion check saw status=DELETED and still blocked (it should pass). Added explicit wait for LB to be fully removed from DB before attempting VPC deletion. 2. **AutoScalingE2E**: The scaling group is marked DELETING but the AutoScalingWorker (10s tick) isn't running in E2E (ROLE=api), so the group record stays in DELETING forever. Modified CountGroupsByVPC to exclude DELETING groups since they're being cleaned up and will be gone soon. Also added better status detection to avoid false negatives.
