branch policies; keep the independent private Collector service separate.

MarkSent ran after the side effects, so a broker copy on another worker could win it and be streamed as a repeat of the first hearing. It now runs before any further DB work, unconditionally so the set is warm before anyone opts in, and never for TRACE, whose path bytes are per-hop SNR.
Storing a full candidate snapshot on every observation was the wrong call. The same node lists got copied thousands of times, about 22 GB on prod. Resolve endpoints live like path hops and drop the column.
