Separate authorities, shared contracts
Identity, messaging, social relationships, content, payments and compute have different risk profiles. XLink is defining an explicit source of truth for each domain and connecting them through versioned commands, events, proofs and receipts.
This makes failover and recovery measurable while reducing the chance that one convenience layer can overwrite another domain's authoritative state.
Long-horizon infrastructure
Multi-cloud design is being developed as an operational discipline. Public production claims will follow only after failover, replay, isolation and recovery gates are independently verified.
