# Roadmap: v1.51 Schema And Contract Consistency

## Result

`v1.51` is complete.

## Phases

- [x] **Phase 85: Schema Mirror Baseline**
- [x] **Phase 86: Schema Tree Doc Boundary**
- [x] **Phase 87: Closure And Regression Audit**

## Outcome

`v1.51` now has:

- a mirrored runtime copy of `promotion-or-reject.schema.json`
- explicit schema-tree README docs under root and kernel `schemas/`
- architecture guidance for public-schema versus runtime-schema ownership
- contract tests that guard the mirror and documentation boundary
