Also located and checksum-matched `tipa16.mp3` to **moon chime** (CC0), resolving its previous unknown-source blocker. `Boss Fight 2.mp3` was missing from this table and is now listed. Runtime references place **Valor of Heroes** in Orbital Ops, not Code City Brawl; **Boss Fight 2** is bundled but has no runtime reference.

 The audio inventory is covered by the individual tracks and pack rows above, plus the eight project-original Heroes vs. Villains cues below. No additional unidentified audio files were found. Existing pack verifications are retained; this pass does not re-establish their earlier byte-match claims.
