Context
Retry-fire capacity requeues now guarantee liveness by excluding due reservations from slot accounting. They deliberately keep countFailure: false and advanceAttempt: false so temporary capacity contention does not consume the failure budget or add exponential backoff.
Follow-up
Define and implement a fair ordering or aging policy for multiple due retry reservations under sustained concurrency saturation. The current sequential reconciliation order can repeatedly prefer the same reservation, so liveness does not guarantee per-retry fairness.
