Phase 1.0BP: one-shot SDL materialization gate

Status: EXACT_SDL_ONLY_MATERIALIZATION_AUTHORIZED_ONCE

Date: 2026-07-29

The BO runner, validator and source-only tests are hash bound. The pinned SDL source is clean and the exact stage, build and archive paths are absent. BP authorizes one invocation of the exact Python expression below. It may execute only the ten reviewed requests and produce the detached SDL source, SDL build tree and libSDL2.a.

The attempt is consumed before hashing or process creation. Any mismatch, timeout, overflow, nonzero result or missing archive stops the attempt. There is no retry, resume or cleanup. The outputs are retained for audit. This gate does not authorize building RetroArch, producing an ELF/map, connecting to a PS5, transferring, installing or executing anything on a device.
