Per ADR-0019, a freeze fires only when confidence, z-score and source count all cross threshold together; divergence is the separate multi-source-disagreement path. While frozen the API serves the last good value with flags.frozen=true. A freeze holds 10 or 30 minutes, extends up to four times, then escalates and stays firing until an operator runs freeze-unfreeze.
