MPI matching — how a candidate match is scored
A deterministic pass runs first; anything not resolved there falls through to weighted probabilistic scoring. This is exactly the mechanism shown live on the MPI review screen — the rule table below is the same configuration that screen renders against.
1 · Deterministic passes (auto-link, no review)
2 · Probabilistic weights
3 · Outcome bands
Data-quality notes handled explicitly in the model: estimated date of birth is a flag on the Patient record (reduces DOB match confidence rather than excluding the field), and previous / preferred names are stored as an array so a name change doesn't read as a mismatch against history.
