Subject: [PATCH] Class v6 census, the pack harness: the sitestats command
 (per-site distinct ratio, bucket sigma, index-bit sigma of a pack's program)
 and the harness-gated accept walk; the attack-pass lane's f8 tool (class v5,
 state leaves) with --load-class for a class string; the census script's state
 and era-hex arguments
