Download these exact selections locally and keep the mapping, source URLs, CC0-1.0 license and available format metadata. Check HTTP responses before saving: if a file is unavailable, report it rather than saving an error response as audio or silently substituting another file. Set metadata at https://sfxmint.com/api/v1/sets/platformer?format=mp3 describes defaults, which may differ from my choices above.

Connect playback to each matching event; report events that do not exist in this project. Respect audio unlock and existing mute/volume controls. Verify playback and local-file loading, then let me preview the result. Report missing files and any listening checks still needed; file metadata alone is not listening approval. Preserve originals and document any permitted processing. Do not replace these selections or call paid generation services without my authorization.
