- CentrifugoRecorder records publish/broadcast requests (method, path,
whether the API key matched, JSON body) and binds loopback only
- BroadcastGolden load/write, NormalizePublications (timestamps, actor,
captured ids only) and DiffPublications (structural, key order ignored)
- RecordBroadcasts runs a flow or one step against a loopback backend
- summer parity:broadcasts wraps it; README documents format and rules
