- 36 files move into the module whose AGENTS.md already claimed them: Engine/, Synth/, Modulation/, Params/, Plugin/, GUI/, EffectUnits/, Resources/ - Source/engine, modulation, params, plugin and synth become Engine, Modulation, Params, Plugin and Synth, matching the directories that already hold code - ExactCompare.h stays at the Source/ root as the one shared header - SERUMALT_INCLUDE_DIRS adds one include directory per module, so the 31 parent-relative includes become plain names with no path prefix - the module AGENTS.md files list owned files instead of describing a move that had not happened, and README.md and AGENTS.md describe the real tree Verified: the harness passes CTest, the Linux VST3 and Standalone link, the Windows cross-build passes its module checks, each configure exposes only its own targets, no first-party warning line appears, and the generated Windows manifest is unchanged.
