pub fn raw_buffer_candidates(
registry: &BufferRegistry,
buffer_locals: &HashMap<BufferId, BufferLocals>,
active: BufferId,
) -> Vec<(RawCandidate, RoutingPayload)>Expand description
Build the buffer-picker candidate set: every entry in the
registry, with the active buffer floated to the bottom and
tagged (current) in marginalia. Free function because the
picker module is renderer-agnostic; this composes both
RawCandidate + RoutingPayload shapes against a
BufferRegistry borrow. Phase 5.8.AC.1: hoisted from TUI App.
