Phase 1.0CJ: native SDK stage design gate

Status: NATIVE_ROOT_CLEAN_FULL_SDK_TREE_BOUND_STAGE_DESIGN_ALLOWED

Date: 2026-07-30

The CI cleanup left the exact native root absent. The pinned SDK contains 2,923 regular files, no symbolic links and 29,406,271 bytes. A normalized read-only tar stream binds the entire tree, not merely selected files.

CJ permits source implementation and fake tests for one exclusive native SDK copy followed by normalized tree verification. The build must reference only the verified native copy. No copy, CMake invocation, build, export, target or device action is authorized under CJ.
