# Phase 1.0BX: changed-files timeout and read-only fixture gate

Status: `BW_CONSUMED_CHANGED_FILES_TIMEOUT_WINDOWS_GIT_STAGE_FIXTURE_ALLOWED`

Date: 2026-07-30

The single BW attempt completed both source checks, detached stage creation and
both patch check/apply pairs. It then timed out in WSL Git
`verify_changed_files` after ten seconds. The process group was terminated.
The stage exists; the build directory and archive do not. CMake and the SDL
build were not invoked.

BX permits one exact read-only Windows Git `diff --name-only` fixture against
the existing stage. It permits no cleanup, output reuse, patching, CMake,
build, retry or device action.
