Struct MoveCounts 

pub struct MoveCounts {
    pub subjects: BTreeMap<String, u64>,
    pub rows: BTreeMap<String, u64>,
    pub left_behind: BTreeMap<String, u64>,
    pub ann_log_appended: u64,
    pub live_policies_left_behind: u64,
    pub grants_in_force_left_behind: u64,
}

What a move did, per route and per table.

left_behind is not an error column. A per-namespace aggregate with no subject cannot be split across a partitioning move; separately identified operational records have no subject route at all. They stay, and the caller is told rather than left to discover them.

Fields

subjects: BTreeMap<String, u64>

Subjects moved, keyed by the rendered route key. A routed class with no rows appears here with zero — that is what makes the map verifiable by its caller, and what makes the same map re-runnable against each backend of a split store.

rows: BTreeMap<String, u64>

Rows written, keyed by table. Derived rows appear here and in no route.

left_behind: BTreeMap<String, u64>

Rows left where they were, keyed by table, with the reason in the docs above rather than in the data.

ann_log_appended: u64

Entries appended to ann_write_log for the source and target namespaces.

live_policies_left_behind: u64

Tool policy rows left in the source that are not soft-deleted. Authorization state is never carried, so these are the rows an operator still has to decide about; left_behind counts every row that stayed.

grants_in_force_left_behind: u64

Tool grant rows left in the source that are in force at the instant the move judged them (see MoveRequest::now_micros): granted, not invalidated by a registration, and not expired.
