# Phase 1.0CF: repeated configure timeout and cleanup gate

Status: `CE_CONSUMED_MOUNTED_BUILDROOT_UNSUITABLE_EXACT_CLEANUP_ALLOWED`

Date: 2026-07-30

CE again passed all pre-CMake operations. CMake made successful compiler and
try-compile progress but timed out after 600 seconds without a cache or archive.
Further timeout increases on the mounted buildroot are rejected.

CF permits one cleanup of only the exact derived stage and partial build, using
the same bounded methods as CC. It does not authorize another materializer
attempt. The next source phase may design and host-test a WSL-native stage/build
with exact archive export, but may not invoke it under CF.
