Feature	Notes
Entity replication	Per-field deltas through Property<T>
Static entities	Full snapshot on scope entry, no per-tick diff tracking
Replicated resources	Singleton values carried by hidden replicated entities
Client-authoritative entities	Opt-in via Protocol::enable_client_authoritative_entities()
Entity publication	Client-owned Private, Public, and Delegated states
Reconnect correctness	Re-sends in-scope entities and resources after reconnect

Feature	Notes
Server-owned default model	Ordinary server-spawned entities/resources are server-owned
Authority delegation	Clients can request temporary authority over delegated entities/resources
Server authority control	Server can grant, deny, revoke, and reclaim authority
Scope-aware authority	Authority operations respect scope and delegated status

Feature	Notes
Rooms	Coarse interest groups
UserScope	Fine-grained per-user visibility
Scope exit policy	Despawn or persist/freeze when leaving scope
Priority-weighted bandwidth	Per-entity/per-user gain with token-bucket send loop
Per-connection bandwidth budgets	Target bytes per second
Message backpressure	Reliable channel queue limits return errors instead of silently growing forever

Feature	Notes
Typed messages	Reliable/unreliable, ordered/unordered, sequenced, and tick-buffered modes
Typed request/response	Request trait associates each request with its response
Tick synchronization	Server/client ticks, RTT-aware timing, interpolation fractions
Prediction primitives	TickBuffered, CommandHistory, local duplicate patterns
Lag compensation	Historian snapshot buffer, including component-kind filtering

Feature	Notes
WebRTC transport	Native and Wasm clients; DTLS; recommended production path
UDP transport	Native plaintext transport for dev/trusted/custom-secured deployments
Local transport	In-process deterministic tests and harnesses
Link conditioning	Loss, latency, and jitter presets for supported transports

Feature	Notes
Bevy adapter	Server, client, shared protocol helpers, replicated resources
Macroquad/core path	Uses naia-client directly with mquad support
Custom world integration	Implement WorldMutType and WorldRefType
Metrics integration	naia-metrics and naia-bevy-metrics
Contract test harness	Scenario/spec coverage for replication, authority, scope, and transport behavior
Benchmarks and fuzzing	Criterion/iai-callgrind benches and protocol/serde fuzz targets

Feature	Notes
Bit-level serialization	Compact bit-packing
Quantized numeric types	Fixed-width and variable-width integer/float helpers
zstd compression	Optional default, custom dictionary, and dictionary-training modes
Enum messages	Supported by #[derive(Message)]
