Two-phase set (2P-Set) CRDT: add and remove sets merged for membership.

Category: State CRDTs · Protocol: crdt-two-phase-set/v1

When to use

Replicated sets with removals that must converge (ban lists, revoked IDs).

When not to use

Elements that can be re-added after remove without tracking history (consider OR-Set patterns). Grow-only data (use G-Set).
