Struct HistoryIntent 

pub struct HistoryIntent {
    pub kind: &'static str,
    pub detail: String,
}

A History entry the apply intends to append. Not an event, and not an HistoryEvent — constructing one would be the second History system contract §7 prohibits, and appending one is the thing a plan must not do.

The vocabulary is the existing one, and it is short

The only kind a plan can currently predict is transition_accepted, because the only History event a bulk operation can cause is the one the status seam writes. A bulk field change appends nothing because this path writes the field directly and does not route through tix edit, whose estimate and cycle-membership changes do append their own typed History events.

So “this plan appends no History” is a prediction about an absence, and the plan reports it as the empty list rather than inventing a name. The apply reaches the same answer from the other direction: the field write goes through Store::update and the transition goes through Store::set_status, and only the latter appends.

Fields

kind: &'static str

A crate::model::HistoryEventKind::as_str spelling. A &'static str and not the enum, because a plan must not be able to construct one — but it must be checked against the enum’s spelling by the apply, and a test pins that every kind a plan emits is one the model can actually produce.

detail: String
