# ADR-CE-009: Single Coherence Object
|
||
|
||
**Status**: Accepted
|
||
**Date**: 2026-01-22
|
||
**Parent**: ADR-014 Coherence Engine Architecture
|
||
|
||
## Context
|
||
|
||
Building domain-specific coherence systems (one for AI, one for finance, one for medical) leads to:
|
||
- Duplicated effort
|
||
- Inconsistent semantics
|
||
- Maintenance burden
|
||
|
||
## Decision
|
||
|
||
**Single coherence object - once math is fixed, everything is interpretation.**
|
||
|
||
The Universal Coherence Object:
|
||
- Nodes: d-dimensional state vectors
|
||
- Edges: Restriction maps ρ_u, ρ_v
|
||
- Energy: E(S) = Σ w_e|r_e|²
|
||
- Gate: E < θ → allow
|
||
|
||
Domain-specific interpretation:
|
||
| Domain | Nodes | Edges | Residual | Gate |
|
||
|--------|-------|-------|----------|------|
|
||
| AI | Beliefs | Citations | Contradiction | Refusal |
|
||
| Finance | Trades | Arbitrage | Regime mismatch | Throttle |
|
||
| Medical | Vitals | Physiology | Clinical disagreement | Escalation |
|
||
|
||
## Consequences
|
||
|
||
### Benefits
|
||
- One implementation, many applications
|
||
- Proven math applies everywhere
|
||
- Domain experts focus on interpretation, not implementation
|
||
|
||
### Risks
|
||
- Abstraction may not fit all domains perfectly
|
||
- Requires mapping domain concepts to universal structure
