In AskAiRank I ignore single days and look at several weeks of data before deciding anything moved. One data point isn't enough to know what's real.01 Oct 2026 09:31 +0000at://did:plc:vsiiv2bjeg7bwalgrlie2aop/app.bsky.feed.post/3mwskeqnyss2chttps://bsky.app/profile/nickspiz.bsky.social/post/3mwqcme4voe24Shipping got cheap.

The author said it works but also called it a Frankenstein. I use AI for most of my code and I still think someone has to read the diff.

When a push might mean a surprise invoice, you deploy carefully.
