// Scenario (SCN-collect-video-storage-keys):
//   Deriving the object keys backing a video note for cleanup must (a) cover the
//   video, its sibling .torrent, and the thumbnail, (b) decode percent-encoded
//   paths, and (c) NEVER include URLs outside the owner's bucket base (so we
//   can't delete objects we don't own). Pure + deterministic.
