# Phase 1.0CI: native SDK bottleneck and cleanup gate

Status: `CH_CONSUMED_MOUNTED_SDK_PROBE_BOTTLENECK_EXACT_NATIVE_CLEANUP_ALLOWED`

Date: 2026-07-30

CH passed every preconfigure operation on the native WSL root. Configure then
progressed through successful symbol try-compiles but timed out after 600
seconds. The scratch tree was native; compiler and sysroot remained mounted.
The pinned SDK is only 29,406,271 bytes, so native SDK staging is the next
bounded remediation candidate rather than another timeout increase.

CI permits one cleanup of only `/tmp/chimera-gfx-phase10ch`, with its SDL
worktree removed through the originating Git administration before the exact
root is recursively removed. No retry, SDK copy, build or device action is
authorized in CI.
