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,
}

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, so it stays, and the caller is told rather than left to discover it.

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 under the target namespaces.
