# RTT/1 — Coverage Report (Docsbook Edition)
**Engine:** RTT/1  
**Mode:** S‑mode  
**Session:** rtt=1 · coherence=declared · drift=bounded · paradox=structural  

This coverage report summarizes the structural completeness of the RTT/1 engine.  
It documents which layers, modules, and surfaces are implemented, tested, documented, and integrated — and which remain pending.

RTT/1 is a clarity‑first structural engine.  
Coverage is measured structurally, not semantically.

## 5. Coverage Summary

RTT/1 is **structurally complete**:

- All layers implemented  
- All layers documented  
- All layers tested  
- All layers integrated  
- CI pipeline operational  
- Front‑end wrapper functional  
- Canon alignment preserved
