ludic.base: a queue's fact records come round again (q_rec / q_ring_add), used by effects, clock, wallet, weather, tracks, needs, fire, settings, update, steps, crafting, shop, gear, hints, session and photo instead of a new record per fact; the minimap's marks cleared and rubbed out in place, its scale steps without a list; the clock's dice seeded again, not made again; once-per-join, per-save and pool-miss paths declared
