The go-live decision, made of evidence instead of enthusiasm.

An AI assistant is wired into the client's invoice coding and everyone wants it live on Monday. This gate is what stands between the demo and the ledger: five acceptance criteria committed and hashed before any result was seen, a labelled sample from the client's own history, and a confidence threshold you must tune yourself against the live accuracy-versus-coverage trade-off. Sign-off unlocks only when every criterion passes. Then week six arrives, the vendor mix shifts, and the same harness catches the drift and pulls the approval. Synthetic model and labels; the harness is the product. Runs entirely in your browser.

Auto-approve when model confidence ≥ 0.84

Both curves are computed live from the 300-invoice acceptance sample. Slide left and the machine does more with less care; slide right and the human queue swallows the business case. The window where every criterion passes is narrow, and finding it is the job.
