Phase 1.0BY: Windows Git stage fixture failure and file-hash gate

Status: BX_CONSUMED_CROSS_PLATFORM_WORKTREE_UNREADABLE_EXACT_FILE_HASH_FIXTURE_ALLOWED

Date: 2026-07-30

The single BX fixture failed with exit code 1 and fatal: not a git repository: (NULL). Windows Git therefore cannot audit the WSL-created worktree through this route. No build or cleanup followed.

BY permits one PowerShell read-only fixture: read the stage .git indirection and calculate SHA-256 for the four exact patch target files. No directory enumeration, Git invocation, cleanup, output reuse, CMake or build is allowed.
