FAL models poll 404s every run since 2026-11-12 21:46 (removed endpoint in endpoint_id filter?) #641

Since 2026-11-12 21:46 UTC, every fal models poll has failed with fal models fetch failed: 404 Not Found: 6 ingest_failed events, latest 23:01, job models-poll. In the same run, fal fal-ai/video-prompt-generator llms.txt: 404 Not Found was also logged.

An unfiltered GET https://api.fal.ai/v1/models?limit=1 returns 200. So the 404 most likely comes from the endpoint_id= filtered request (src/server/providers/fal.ts:240-252): FAL removed an endpoint (likely fal-ai/video-prompt-generator), and the whole filtered batch now 404s.

Fix: confirm the cause. Then treat an endpoint that FAL no longer serves as gone, so its row is deprecated through the normal poll path. Don't let it fail every poll. Don't swallow other 404s. Report the missing id loudly with its location.
