Diaspora
Source: Wikipedia Topic: Divergent copies, long-latency federation, and lineage-preserving evolution.
Core idea
Diaspora treats copied minds and long-delay communities as legitimate divergent branches with preserved lineage rather than as corruption of one central identity.
Harness takeaway
Branch lineage and delayed federation should be first-class harness concepts. Divergence is not failure if provenance and merge semantics remain explicit.
