fix(rectification): collect dated events, then distinguish with conflict probes

Empty ledgers stay in natural-language collection. After the first dated
event, dasha conflict probes reverse-infer 前事 and block offer until
answered. Unique-minute confirmation stays closed at a representative
time; adopt reverse-verifies remaining probes. Records BUG-348–351.
