ADR-0021: Continuity & hot failover

Status

Accepted (Phase 11)

Decision

• ContinuityPlane replicates Wasm frames + memory segments to N in-process peers.
• Partition tests recover latest replica after killing a majority of holders.
• Raft KV replication complements frame continuity for shared state.

Honesty — “zero packet loss”

We demonstrate zero data loss via replicated logs + deterministic replay equality checks. We do not claim lossless UDP/QUIC delivery on the wire.
