# Phase 96: Closure And Regression Audit - Context

**Gathered:** 2026-04-11
**Status:** Implemented and verified
**Mode:** Final closure phase for `v1.54`

<domain>
## Phase Boundary

Close `v1.54` with subprocess-error regression coverage, maintainability-budget
confirmation, and a fresh full-suite baseline.

</domain>

## Implementation Decisions

### Locked decisions

- require maintainability-budget confirmation because `aitp_service.py` is still
  watchlisted
- keep backlog `999.11` marked partial; this slice does not yet reduce the
  runtime state-file surface or planning noise

</decisions>
