# Phase 102: Closure And Regression Audit - Context

**Gathered:** 2026-04-11
**Status:** Implemented and verified
**Mode:** Final closure phase for `v1.56`

<domain>
## Phase Boundary

Close `v1.56` with targeted adopted-fixture coverage and a fresh full-suite
baseline.

## Implementation Decisions

### Locked decisions

- keep backlog `999.12` marked partial because structural-versus-behavioral
  separation is still open
- require a fresh full-suite baseline because shared test helpers can regress
  files beyond the three directly touched tests
