Phase 1.0CX: isolated reproducibility build gate

Status: FIRST_ARTIFACT_AUDITED_ONE_ISOLATED_REBUILD_ALLOWED

Date: 2026-07-30

CX permits one independent build in the absent native root /tmp/chimera-gfx-phase10cx. The bound builder exports only tracked bytes from the exact target-source commit, recopies and rehashes the audited SDL package, and performs a full object-free build. It succeeds only when both ELF and map match the first build byte-for-byte.

The source archive and native root are consumed evidence and may not be cleaned or reused. No retry, networking, transfer, installation or PS5 execution is authorized, and even a match does not itself make the artifact eligible.
