A podcast/music note published as a native kind-30078 (content url = an .ogg/
.mp3 audio file, imeta `m audio/*`) was accepted by convertEventToVideo (it has
a url) and rendered as a broken <video> — black frame + audio on Chrome/FF,
MEDIA_ERR_SRC_NOT_SUPPORTED on Safari/iOS — since bitvid has no <audio> player.
The existing audio guard only covered the NIP-71 ingest path, not native events.
convertEventToVideo now marks such notes invalid ("audio-only source (no video)")
so every ingestion path that already drops invalid filters them: main feed buffer,
author/channel batch fetch, and local ingest. Audio-only = no magnet AND no
`imeta m video/*` AND (an `imeta m audio/*` variant OR an unambiguous audio URL
.mp3/.m4a/.aac/.wav/.flac/.opus/.oga/.weba). `.ogg` alone is NOT filtered
(ambiguous → video/ogg); only when imeta says audio. A video imeta variant wins.
Direct open-by-nevent is intentionally unaffected — an explicit link still loads.
Near-term half of TODO #60 (the future dedicated Audio tab remains open).
Tests: tests/video-schema-and-conversion.test.mjs (+5, 8/8). Lint + build green.
