# Component 24 Verification: Fleet-level Sentinel Link Coordination
|
|
|
|
## Status: Already Implemented
|
|
|
|
Component 24 (Fleet-level sentinel link coordination) was already fully implemented in `ratecontrol.go` at the time this bead was created.
|
|
|
|
## Verified Implementation
|
|
|
|
All requirements from the plan are present:
|
|
|
|
1. **Zone-level idle detection with sentinel designation**
|
|
- Function: `designateSentinel()` (line 291)
|
|
- Designates lexicographically smallest MAC as sentinel
|
|
- Sentinel runs at 5 Hz (RateSentinel), others at 1 Hz (RateFleetIdle)
|
|
- Test: `TestZoneIdleDetectionAndSentinelDesignation`
|
|
|
|
2. **Fleet-wide idle state tracking**
|
|
- Field: `fleetIdle bool` (line 63)
|
|
- Set when all zones are idle (line 285): `rc.fleetIdle = allZonesIdle && len(rc.zones) > 0`
|
|
- Test: `TestFleetIdleDetection`
|
|
|
|
3. **Prediction engine preemptive zone ramping**
|
|
- Method: `RampZone(zoneID string, rampAdjacent bool)` (line 189)
|
|
- Ramps all nodes in zone to active rate (50 Hz)
|
|
- Optionally ramps adjacent zones to sentinel (5 Hz)
|
|
- Test: `TestRampZonePredictionEngine`
|
|
|
|
4. **1 Hz floor rate for fully-idle fleet**
|
|
- Constant: `RateFleetIdle = 1` (line 19)
|
|
- Applied to non-sentinel nodes in `designateSentinel()` (line 308)
|
|
|
|
## Tests Passing
|
|
|
|
All 15 ratecontrol tests pass, including:
|
|
- Zone-aware idle detection and sentinel designation
|
|
- Fleet idle state tracking
|
|
- Adjacent zone ramping on activation
|
|
- Prediction engine RampZone method
|
|
- Sentinel redesignation on node disconnect
|
|
|
|
## Implementation Date
|
|
|
|
The commit history shows this was implemented in commit `9c36b0d`:
|
|
```
|
|
feat(bf-28dv): implement zone-aware rate control (Component 24)
|
|
```
|
|
|
|
This bead serves as documentation that Component 24 is complete.
