- Model, controller, and mapper object creation no longer re-scans the framework mixin folders (a directory listing plus a
createObjectandgetMetaDataper file) on every materialization. The mixin-integration plan is now built once per application and reused, and the per-method$willBeOverriddenByMixinlookup is precomputed — cutting model-instance creation roughly in half (everynew()and every finder row was paying the full cost). This is the regression behind slow test-suite and request times reported on 4.0.x (#3213)
