Recommendations are advisory. Nothing is assigned automatically and nothing is written back to FMS — every invoice waits for a reviewer. Confidence is a measured probability of correctness, shown separately from historical consistency. Recommendations sourced from the Invoice content model carry a known miscalibrated confidence band and are marked confidence pending calibration; treat those percentages as indicative until fresh calibration data is available. Confidence from same-vendor behavioural matches, same-vendor history and reference codes is calibrated.
