# @suaveplan/r3f-networking - R3F-tier multiplayer state synchronisation: interpolation, client-side prediction, snapshot diffing, server reconciliation FSM, React hooks + React-Three-Fiber components. Transport-agnostic — composes any @suaveplan/network Transport.

## Summary

R3F-tier multiplayer state-synchronisation for React-Three-Fiber scenes.
Composes any `@suaveplan/network` `Transport` (canonical:
`@suaveplan/network-transport-webrtc`), `@suaveplan/diff` for snapshot
deltas, `@suaveplan/fsm` for the reconciliation state machine, and
`@suaveplan/serialize` for the wire codec.

## What this package owns

- **Interpolation** — frame-loop smoothing of remote-peer transforms
  ([`core/interpolation`](./src/core/interpolation/interpolation.md)).
- **Client-side prediction** — local input applied immediately, reconciled
  against authoritative snapshots
  ([`core/prediction`](./src/core/prediction/prediction.md)).
- **Reconciliation FSM** — `synchronized → diverged → resyncing` state
  machine driven by divergence magnitude
  ([`core/reconciliation-fsm`](./src/core/reconciliation-fsm/reconciliation-fsm.md)).
- **Snapshot diffing** — RFC-6902 JSON Patch between authoritative
  snapshots via `@suaveplan/diff`
  ([`core/snapshot-diff`](./src/core/snapshot-diff/snapshot-diff.md)).
- **Wire codec** — Zod-validated frame encode/decode via
  `@suaveplan/serialize`
  ([`core/wire-codec`](./src/core/wire-codec/wire-codec.md)).
- **Entity sync + interest management**
  ([`sync/entity-sync`](./src/sync/entity-sync/entity-sync.md),
  [`sync/interest-manager`](./src/sync/interest-manager/interest-manager.md)).
- **Server authority** with anti-cheat hooks
  ([`authority/server-authority`](./src/authority/server-authority/server-authority.md)).
- **In-memory transport** — deterministic real `Transport` implementation
  for integration tests
  ([`transport/memory-transport`](./src/transport/memory-transport/memory-transport.md)).
- **React hooks** — `useNetworkSync`, `useNetworkedEntity`,
  `useNetworkPredict`.
- **R3F components** — `<NetworkProvider>`, `<NetworkedEntity>`,
  `<NetworkStats>`.

## Observability

OTel meter `@suaveplan/r3f-networking`. Histograms
`r3f_net.snapshot_dispatch_ms` and `r3f_net.prediction_divergence`;
counters `r3f_net.snapshots_total{outcome}` and
`r3f_net.peer_events_total{event}`.

## Error registry

`defineCodes("R3F_NET", […])` — 8 codes:
`SNAPSHOT_OUT_OF_ORDER`, `PEER_DROPPED`, `PREDICTION_DIVERGED`,
`INVALID_OPTIONS`, `INVALID_SNAPSHOT`, `DISPOSED`, `TRANSPORT_FAILED`,
`ABORTED`.
