Fate-bounded-temporal-unit-as-received-ordinance — a period of time that is not merely a calendar segment but an ontological unit with its own character, biologically anchored, with a determinate (if unknown) end, existing within the pre-cosmic fate-texture. The boundaries are legible through signs. The temporal analog to the Piacenza Liver: a local instance of the cosmic pattern, livable-within, readable at the edges.
