Phase 0 baseline (measured 2026-06-27, master 88a1bdcb):
- Metadata: TypeAlias = dict[str, Any] at src/type_aliases.py:6 (Phase 1 target)
- hasattr(f, 'path') sites: 29 (gui_2.py:18, app_controller.py:10, aggregate.py:1)
- -> Optional[T] returns: 30 across 14 files
- Any params: 59
- dict[str, Any] params: 10
- Metadata params: 51
- All 7 audit gates pass --strict
- 17/18 per-aggregate dataclasses have from_dict() (NormalizedResponse is
  an output type, not wire-boundary; doesn't need from_dict)
