AI that overturns your migration plan with proof, not opinions.
Compat Archaeologist decides whether you can leave MongoDB on evidence, not paper. It reconstructs how your app really uses the database from data, query logs, code (Muse Spark) and Atlas (MongoDB MCP Server), then makes AI prove every claim: Muse writes the probes, MongoDB referees them, and FerretDB is tested against them. On our demo app, a +$20k “migrate” case flipped to −$99k “stay” at the first finding: aborted transactions silently don’t roll back. Run with the same rules, the control app gets GO. The verdict lands in ASI:One as an interactive card.
