# ADR-CE-021: Shared SONA
|
|
|
|
**Status**: Accepted
|
|
**Date**: 2026-01-22
|
|
**Parent**: ADR-014 Coherence Engine Architecture
|
|
|
|
## Context
|
|
|
|
Both RuvLLM and Prime-Radiant use SONA for adaptive tuning:
|
|
- RuvLLM: Quality thresholds, routing weights
|
|
- Prime-Radiant: Coherence thresholds, escalation triggers
|
|
|
|
Running two SONA instances wastes resources and may learn conflicting adaptations.
|
|
|
|
## Decision
|
|
|
|
**SonaIntegration shared between ruvllm and Prime-Radiant.**
|
|
|
|
Shared components:
|
|
- `SonaEngine`: Single instance with multiple learning targets
|
|
- `ReasoningBank`: Unified pattern storage
|
|
- `EWC++`: Consolidated knowledge across both systems
|
|
|
|
Configuration:
|
|
```rust
|
|
pub struct SharedSona {
|
|
engine: SonaEngine,
|
|
llm_targets: Vec<LlmLearningTarget>,
|
|
coherence_targets: Vec<CoherenceLearningTarget>,
|
|
}
|
|
```
|
|
|
|
Learning coordination:
|
|
- Both systems contribute trajectories
|
|
- EWC++ prevents forgetting across domains
|
|
- Patterns accessible to both systems
|
|
|
|
## Consequences
|
|
|
|
### Benefits
|
|
- Unified adaptation reduces resource usage
|
|
- Cross-domain learning (LLM patterns help coherence, vice versa)
|
|
- Consistent behavior across systems
|
|
|
|
### Risks
|
|
- Coupling between systems
|
|
- Bad learning in one domain affects both
