Addresses "some NIP-71 videos don't play / he has multiple links" + "speed
the liveness check + don't render unplayable".
- Phase 1 — multi-source capture: nip71IngestAdapter collectVideoSources()
exposes a `sources` list (all video imeta urls, in order; audio/image
excluded; deduped) so mirrors are preserved (the adapter previously kept
only one url).
- Phase 2 — multi-source liveness: urlHealthController.probeUrlList() probes
every candidate (primary + sources) via the existing video-element
playability probe — healthy as soon as one source plays, offline only if
ALL fail. So a dead primary host no longer hides a video with a live
mirror. (Card hide policy in cardSourceVisibility was already correct.)
- Phase 3 — speed: URL_PROBE_TIMEOUT_MS 8s -> 4s for a fast verdict so dead
cards hide quickly; WebTorrent swarm probe stays generous.
Remaining (TODO #5): player-side fail-over at play time; hide-until-verified
for foreign ingested videos. Tests + mutation-verified (collectVideoSources
video-only filter, probeUrlList first-ok/offline/timeout). 1271/1272 unit
(known UploadModal flake).

Deep dive into the "nothing loads / Fetching recent videos… hangs" symptom
found the real blocker: it was NOT the moderation/WoT stage (that uses
cached reads and passes unknown authors through clean). It was the feed's
resolve-posted-at stage.
resolveVideoPostedAt() short-circuits when a video has nip71.publishedAt,
otherwise it does a per-video `nostrClient.hydrateVideoHistory()` network
fetch (looking up kind-30078 history). Foreign NIP-71 videos have no such
history, and the ingest adapter wasn't setting nip71.publishedAt — so a
burst of ~32 ingested videos triggered ~32 blocking history fetches that
stalled the render and flooded relays.
Fix: the ingest adapter now surfaces nip71.publishedAt from the NIP-71
published_at tag (falling back to created_at). The feed short-circuits and
never fetches history for ingested videos. Re-enables FEATURE_NIP71_INGEST
by default now that the hang is addressed.
Tests: adapter published_at extraction + created_at fallback;
mutation-verified. 1237/1238 unit (known UploadModal flake).

buildVideoFromNip71Event() converts a NIP-71 video event published by
another Nostr app (kinds 21/22/34235/34236) into a bitvid video object
shaped like convertEventToVideo's output, so ingested videos flow through
the existing feed pipeline (moderation, trust, NSFW gating, rendering).
Reads the imeta variant + standard NIP-71 tags (not bitvid's JSON
content): url/magnet, dim->width/height, image->thumbnail, x/ox hashes,
i/magnet->infoHash, title, summary->description, t->hashtags, duration.
Safety:
- content-warning -> isNsfw so ALLOW_NSFW_CONTENT + blur thresholds apply.
- skips bitvid's own outbound mirrors (["client","bitvid"]) to avoid
double-listing content already present as canonical kind-30078.
- never marks foreign content private (no encryption in NIP-71).
- stamps source:"nip71-ingest"/foreign:true provenance markers.
Pure + dependency-free; mutation-verified (mirror-skip, nsfw mapping).
