The 54 editor engine tests move to packages/core/tests/editor with their helpers, importing Core's public subpaths or source modules relatively. The package gains test and typecheck scripts; the first type check fixed nullable lookups, stale imports, and renderer doubles, and graph events now declare the GraphEventRenderer surface they invalidate. The engine baseline drops to 534 files.
