A clip whose file its host no longer has says so where the player stood, with the file's link, instead of sitting as a dead player under "Tap to play". A post's video "won't play" (Adam, 2026-11-01): the mp4 had been deleted from Primal's blossom, which answers a 404 with no CORS headers, so the probe couldn't read the status and the box waited for a tap that loaded nothing — no client renders it (the reply under the post says as much) and no other blossom host has the hash. The player is the first to know: its original failing now tries the server's copy once (a file the browser can't decode fails the same way, and the copy plays that one), and the copy failing too marks the clip gone for a day — the line and the link in the box, its cover, play button and controls off, a short box; the next paint of the post says it at once with no request, the media warm-up and the in-view hook leave it alone, and the videos grid leaves it out as it did a 404 the probe could read. Outside the feed the box used to be hidden on an error before anything was said; it gets the line too. tools/video-gone-test.js serves the clips from a second origin without CORS, one of them a 404, and checks the line, the untouched live clip and the silent repaint
