Config.fetch (exactly "1", read in from_args_and_env through the lookup), SaveAttachment
{room, event} on PersonaReply with the tempo_vote_beat_s present() pattern, a conditional
unrequired schema property, SAVE_FAULT refusal when the flag is off or the room/event is
out of bounds, Step::Answered carries zero to two notice lines (open, then save), and a
gated fetch step: NoStore decided before any request, the saver called with the receipt's
room id, one fixed line per outcome with the relative path only on success.
