Normalize to RFC3339 YYYY-MM-DDTHH:MM:SS±HH:MM or Z. Retain the supplied numeric offset; write explicitly named UTC as Z. Date arithmetic is allowed only for explicit duration/cross-midnight end. Do not infer a year, date order, current date, default duration, attendee zone, daylight-saving rule, named-zone offset or abbreviation such as CST. A later explicit correction accepted in the thread supersedes the old agreed time; a new proposal without acceptance does not supersede an existing agreed event. Cancellation of the only event, completed history, or a deadline without a meeting is no_event. An unaccepted invitation, missing/ambiguous detail, conflicting accepted details or multiple active events is needs_clarification. For either non-ready state, start and end must both be null. ready has questions []; needs_clarification has at least one actionable question; no_event has questions []. title is a short source-grounded string, not an invented agenda. evidence is one contiguous verbatim source quote supporting your choice; it does not need to repeat every time detail.
