# Phase 1.0CU: exact SDL header export gate

Status: `HEADER_TREES_BOUND_ONE_HOST_EXPORT_ALLOWED`

Date: 2026-07-30

CU binds both header roots consumed by `Makefile.ps5`. The public tree contains
78 regular files (2,400,049 bytes); the generated release configuration tree
contains one regular file (16,566 bytes). Their identities cover every sorted
UTF-8 relative path, byte length and file SHA-256.

One host-only staged export is permitted. Existing destinations, symlinks,
identity drift and partial reuse are rejected. Cleanup, target building,
networking and every PS5 operation remain unauthorized.
