Aspect
nsdef:aspectaspect — where a coordinate stands in Akasha Time, held as SET MEMBERSHIP rather than a field: aspect:prospective (authored in advance — a plan or a scenario step) and aspect:perfective (the record: it happened), with set:aspect:prospective / set:aspect:perfective holding the coordinates. Membership is ADDITIVE and never removed — running a scenario adds perfective and keeps prospective, so plan and occurrence are two readable memberships instead of one overwritten value, and where they differ is exactly what a record is for (seeds13 law 2: chronon = PERFECTIVE, scenario = PROSPECTIVE, one structure read in opposite times).
