The convert-time guard (17b48cbf) only blocks FRESH events. Audio notes cached
before it existed are rehydrated straight from IndexedDB/localStorage as
already-converted video objects (`sig: "unavailable (cached)"`), bypassing
convertEventToVideo — so they kept showing in the main feed and channel grids.
Extract the audio check into a reusable object-level predicate
`isAudioOnlyVideoObject(video)` (url + magnet + imeta tags) and apply it at every
boundary a cached object can slip through:
- convertEventToVideo now delegates to it (fresh ingest, unchanged behavior)
- PersistenceManager.applyCachedPayload drops audio-only on hydration (purges
the cache going forward)
- NostrClient.getActiveVideos filters it (main feed, immediate effect)
- nostrService.shouldIncludeVideo filters it above the viewer-is-author
short-circuit (channel/author grids, incl. the creator's own channel)
Audio-only = no magnet AND no imeta `m video/*` AND (imeta `m audio/*` OR an
unambiguous audio url); `.ogg` alone stays video. Bumped client.js size baseline
(+6 lines). Tests: video-schema-and-conversion (+3 predicate scenarios, 11/11);
nostr-service + ingest-adapter suites green. Lint + build clean. TODO #60.
