# Phase 112 Summary

Status: implemented on `main`

## Goal

Lock the flexible layer-graph contract before writing production code.

## What Landed

- new helper-level layer-graph contract tests
- service-path status coverage for layer-graph materialization
- CLI registration and real subprocess coverage for `aitp layer-graph`

## Outcome

Phase `112` is complete.
`v1.60` has a real failing-then-passing contract for the layer-graph surface.
