- **fixed** — MessageBus retry-attempts now persist across re-queues instead of silently resetting to 0, preventing unbounded redelivery and ensuring message.failed fires at the retry cap
- **fixed** — hybridSearch controller is now reachable through controller-registry wiring instead of silently null-returning when opt-in flag is set
- **added** — Thompson-sampling prior decay for the model-router bandit with opt-in flag to recover faster after workload shifts in the low-cost bucket

Release train off three dream-cycle landings.

##### Dream Cycles

- **#3062 → #3061** — dream(swarm): MessageBus retry-attempts silently reset to 0 on every re-queue, unbounded redelivery, \`message.failed\` unreachable. Bounded retry counter now persists across re-queues; \`message.failed\` fires at the cap. 220/220 tests. **ACCEPT.** Details in [docs/dream-cycle/dream-gist-2026-08-19.md](https://github.com/ruvnet/ruflo/blob/main/docs/dream-cycle/dream-gist-2026-08-19.md).
- **#3057 → #3056** — dream(memory): \`hybridSearch\` controller was built but unreachable — explicit opt-in flag silently null-returned. Fixed via controller-registry wiring + graceful-retrieval test. Overall recall@10 +0.267 (category B pure-paraphrase regresses -0.133, disclosed). **ACCEPT-scoped.** Details in [docs/dream-cycle/dream-gist-2026-08-18.md](https://github.com/ruvnet/ruflo/blob/main/docs/dream-cycle/dream-gist-2026-08-18.md).
- **#3049 → #3048** — dream(intelligence): discounted Thompson-sampling prior decay for the model-router bandit (opt-in). Recovers ~17.6% faster after workload shift in the low-cost bucket (t=7.00, held); med-bucket null (no generalization, disclosed). **ACCEPT-scoped.** Details in [docs/dream-cycle/dream-gist-2026-08-17.md](https://github.com/ruvnet/ruflo/blob/main/docs/dream-cycle/dream-gist-2026-08-17.md).
