pub type ProjMap = BTreeMap<Box<str>, Vec<usize>>;Expand description
Project-at-emit map (PROJECTION-SUPPORT-DESIGN.md §5.2): table name → the base column
indices this query syncs for it, in ascending (= projected wire) order. Only projected
tables appear; a table absent here syncs full. An empty map ⇒ no projection, so emission is
a pass-through (a '*' query is byte-identical, §7).
