The fleet listing called Counts, the per-section census the repository nav needs: eight aggregates per store, of which a fleet row displays two. A fold invalidates the memo, so during indexing every row went cold at once.

Cold, on tcl (668MB, 42k check-ins): 230ms of census per repository against 80ms for the two numbers. Contributors now reads the maintained contributor table rather than a DISTINCT scan over every event — verified identical across all 25 demo indexes. check-in: c5d8786875 user: dmestas tags: fleet-census
