# Phase 1.0CA: cleanup result and hash-verifier correction gate

Status: `EXACT_STAGE_CLEANUP_PASSED_HASH_VERIFIER_SOURCE_CORRECTION_ALLOWED`

Date: 2026-07-30

The single BZ cleanup completed successfully. The exact stage and its worktree
metadata are absent, while the source checkout remains clean at the pinned SDL
commit. No other temporary worktree was removed.

CA permits only an offline request-graph correction: replace the failing
worktree Git diff with exact SHA-256 verification of the four patch targets
using the hash-bound `/usr/bin/sha256sum`. The resulting hashes must equal the
BY fixture values in exact path order. Materializer invocation, output reuse,
CMake, build and device actions remain unauthorized.
