# Phase 1.0CM: measured configure-timeout correction gate

Status: `NATIVE_ROOT_CLEAN_MEASURED_1800_SECOND_SOURCE_CORRECTION_ALLOWED`

Date: 2026-07-30

CL cleanup succeeded. CK completed 96 native compiler checks in 600 seconds;
SDL's remaining libc, math and platform checks make 1,800 seconds a measured
upper bound with margin. CM permits only changing
`cmake_configure_sdl_only.timeout_seconds` from 600 to 1,800. All commands,
other bounds and scopes remain unchanged. No invocation is authorized.
