|
||
- [x] 5.2 Selects transport based on priority + capability + health.
|
||

|
||
|
||
## 6. Priority router
|
||
|
||

|
||
- [x] 6.2 5 tiers: CRITICAL, HIGH, NORMAL, LOW, BULK.
|
||
- [x] 6.3 CRITICAL messages sent redundantly on 2+ transports.
|
||
|
||
## 7. Round-robin balancer
|
||
|
||
- [x] 7.1 `src/balancer/round-robin-balancer.ts` — `RoundRobinBalancer`.
|
||

||
|
||
## 8. Health monitor
|
||
|
||
- [x] 8.1 `src/health/transport-health-monitor.ts` — `TransportHealthMonitor`.
|
||
- [x] 8.2 Auto-pauses transport when health < threshold.
|
||
- [x] 8.3 Auto-resumes when health recovers.
|
||
|
||
