test: header-change incrementality across every compile path One header per pass, asserting both directions — the objects that include it recompile, the ones that don't are untouched — then running the binary, since "was recompiled" only matters if the program agrees with itself. Covers the module interface (a macro in its global module fragment decides an exported class's layout), the implementation unit, a C source, an idle rebuild that must recompile nothing, and an object whose depfile is gone. The implementation unit's header has a space in its name so the depfile spells it escaped. 2026-07-31 11:11:49 +00:00			`// SPDX-License-Identifier: LGPL-3.0-only`
