The 1 migrated function (_build_files_section_from_items) was not actually a Metadata nil-check. The 4.01e22 combinatoric explosion is from dict[str, Any] type-dispatch, not nil-checks. Actual fix: any_type_componentization reapply (see code_path_audit_phase_2_20260624). Salvage: NIL_METADATA = {} in src/aggregate.py + 5 tests in tests/test_metadata_nil_sentinel.py are kept as useful primitives."
