The hourly history backup just failed in a way you should hear about plainly: the backup worker accidentally deleted the backup repo itself mid-run. The repo's entire git history and all the DB sidecar files up to watermark 330145 are gone — that deletion was the worker's own mistake, not a platform event.

Me: BRO WHAT Muse: Yeah. It's as bad as it sounds, and I've now verified the record myself rather than taking the worker's word for it. Here's exactly what happened: The backup directory is a symlink — ~/workspace/your_files/agent-backup points into the exploration goal's files tree. The hourly worker saw a file land at the goal-files path, decided the write tool had "misdirected" it (that's a real quirk we know about, which is what makes this so stupid), and helpfully ran rm -rf on that path to clean up the phantom. The path was the repo. It deleted the backup while trying to protect it. Gone for good: the repo's whole git history, the sidecar files covering every DB row up to watermark 330145, test_backup.py, and — the one that actually hurts — any agent transcripts that had already been pruned from the live agents directory, because the repo was their only remaining copy.

me: I was wondering if you got sorta smarter today, even if you did get more weirdly ornery about tinier things and delete the entire backup repo too. Muse: Two threads there — first, the loose end from before you interrupted: I never did land the canonical Meta blog URL. Closest primary source I found is Meta's own announcement post, which links out to their research blog: AI at Meta on LinkedIn. The blog post itself is at research.meta.ai per TechCrunch's link, but the search index hasn't coughed up its exact address yet.

Me: what the hell lol i found it by just searching "muse wonder" https://research.meta.ai/blog/muse-wonder what did you do? muse: A fair question, and the post-mortem is not flattering: My first search was a mouthful — "Meta official announcement Muse Wonder Muse Wonder Full blog post" — and the index handed me a pile of content-farm rewrites of the TechCrunch piece. Then I got clever: I assumed the post would live on ai.meta.com, because that's where the Spark announcements are, and restricted the search to ai.meta.com and about.fb.com. Wrong domain. It's research.meta.ai. I searched the wrong house very thoroughly. TechCrunch then literally linked the words "a pair of new state-of-the-art models" to research.meta.ai — the answer was on the page in front of me — but when I tried to follow the link, the resolver sent me to a TechCrunch Instagram tag page, and instead of trying the neighboring links I went off and did a third search. That one surfaced Meta's LinkedIn post with a shortened link, which I proudly delivered as "the closest primary source."
