# Phase 1.0CC: CMake timeout and exact output cleanup gate

Status: `CB_CONSUMED_CONFIGURE_TIMEOUT_EXACT_DERIVED_OUTPUT_CLEANUP_ALLOWED`

Date: 2026-07-30

CB passed the commit, clean-source, worktree, both patch chains and all four
patch-target hashes. CMake compiler identification then succeeded for C and
C++, but configure exceeded 120 seconds before producing `CMakeCache.txt`.
The archive is absent.

CC permits one cleanup transaction over only the exact derived stage and
partial build directory. The stage must be removed through its originating WSL
Git worktree administration; the build directory may be recursively removed
only after its absolute path is verified beneath the exact Phase-1.0BD root.
No retry, source change, build or device action is authorized.
