dashwire_replication 0.2.1

Replicated state for dashwire. Property schema, snapshots, relevancy, spawning, RPCs, and rooms.

Changelog

0.2.1

• Replica.snapshotTick, the server tick of the newest snapshot that carried a replica's state. A predictor reconciling against replicated state pins it to this tick rather than to the input ack, which runs every tick while snapshots are budget-packed and can be deferred or dropped.
• ReplicationClient.inputLeadTicks exposes the adaptive send-ahead lead, so a caller passing an explicit tick to sendInput can pace from it instead of stranding the buffer-depth control loop.

0.2.0

• Predictor<I,S>, a generic client-side prediction engine with input-replay reconciliation (advance per tick, roll back to an authoritative state and replay the not-yet-applied inputs).
• LagCompensation<K,V>, a server-side per-tick history that rewinds tracked entities to the client-rendered tick (interpolated, capped) for lag-compensated hit resolution.
• ReplicationHost.priorityScale, a per-connection snapshot-priority multiplier (the distance-falloff generalization); the priority accumulator is now per connection so scaling stays starvation-fair.
• Tick-indexed input commands, ReplicationClient.sendInput with a redundant unreliable tail that self-heals dropped packets, ReplicationHost.consumeInput/Room.input for authoritative per-tick consumption with hold-last on a miss, and server-driven send-ahead pacing from a per-connection buffer-depth ack. The substrate for client prediction and input-replay reconciliation.
• ReplicationClient.inputTargetDepth tunes the server-side input buffer depth the send-ahead lead converges to (2 default; 1 trades jitter headroom for a tick less input latency).
• Fixed quantizing codec ids rendering differently under dart2js, which made a native host and a web client disagree on the schema hash and reject the join.
• Fixed a leave race where despawning the leaver's entity in a room's onLeave sent on its closed connection.

0.1.0

• Replicated-property schema: Replica/rep<T>/rpc with write and read permission axes and per-field replication modes.
• Sync pipeline: per-connection acked baselines with change-bit delta encoding, quantized codecs (varint, quantized float, vec3, smallest-three quaternion, bool-packing), and importance-versus-starvation priority packing against a byte budget.
• Spawn/despawn with a prefab registry, dormancy with auto-wake, and relevancy filters (always-relevant, per-connection, spatial grid, dependent edges).
• Ownership-checked RPCs with validation tripwires.
• Rooms with fixed tick and an isolate-per-room pool (package:dashwire_replication/server.dart), plus RoomStore snapshot/hydrate.
• TransformReplica, a pose-carrying replica base for shared game schemas.
