The installed ~/.config/mosaic home flattens the repo's packages/mosaic/framework/ prefix: the real file is <home>/runtime/<harness>/settings.json, exactly as launch.ts already resolves it everywhere. The fleet launch composition leaked the repo layout (framework/runtime/...) into the system layer path, so a real installed home failed with COMPOSITION_FAILED while the temp-fixture specs (which mirrored the same wrong prefix) stayed green. Found by the in-box hour-gate dry-run against the installed mos-dev-stage home.
