# Phase 1.0CK: native-SDK SDL materializer one-shot gate

Status: `FULL_SDK_TREE_STAGE_BOUND_ONE_NATIVE_MATERIALIZATION_ALLOWED`

Date: 2026-07-30

The CJ-authorized implementation is committed, pushed and hash-bound. The exact
native root is absent. CK permits one offline invocation: create and verify the
normalized SDK archive, extract it natively, materialize patched SDL and build
the native `libSDL2.a`. Export, RetroArch target build, network and PS5 actions
remain unauthorized. Failure consumes the attempt without retry or cleanup.
