The system's state space is a monotonically expanding, append-only lattice: state only grows (monotonic accumulation from stream ratchets and append-only deletion) because no operation ever removes it (all deletes are additive, all finalization is permanent, all state changes are forward-only).
Two independently derived depth-5 perspectives on the same foundational invariant — accumulation and irreversibility are the same constraint viewed from opposite directions
Depends on (SL): state-is-monotonically-accumulative, no-operation-is-truly-reversible
