Network Code Rules

Server is AUTHORITATIVE for all gameplay-critical state — never trust the client
All network messages must be versioned for forward/backward compatibility
Client predicts locally, reconciles with server — implement rollback for mispredictions
Handle disconnection, reconnection, and host migration gracefully
Rate-limit all network logging to prevent log flooding
All networked values must specify replication strategy: reliable/unreliable, frequency, interpolation
Bandwidth budget: define and track per-message-type bandwidth usage
Security: validate all incoming packet sizes and field ranges
