Cleanup Notes
- Keep function addresses and raw decompiler names when evidence is incomplete.
- Add recovered semantic names only when they are supported by strings, GUIDs,
protocol use, or direct call context.
- Avoid changing control flow in this source without a separate behavioral
analysis pass.
