Keep <code>RemoteFunction</code> calls short and bounded.</li>\n<li>Use <code>RemoteEvent</code> for reliable state changes. It is not ordered relative to property or attribute replication: use one explicit state channel or version the state when ordering matters. Reserve <code>UnreliableRemoteEvent</code> for replaceable data such as VFX and snapshots.</li>\n<li>Unreliable is not automatically faster: delivery is unordered, packets may be dropped, and payloads should stay at or below the documented 1000-byte limit.</li>\n<li>Measure payload size and fire rate under load; packet-size estimators are not an official wire-format spec.</li>\n<li>Check numbers for NaN and infinity (<code>x ~= x</code>, <code>math.abs(x) == math.huge</code>) first: <code>NaN</code> defeats <code>&lt;</code>/<code>&gt;</code>. Strings: <code>utf8.len(s)</code> catches malformed UTF-8 that fails a DataStore save.</li>\n<li>Serialization decides validation: functions arrive as <code>nil</code>, metatables are stripped, mixed-key tables are mangled, <code>nil</code> in a table truncates the payload, and tables are copies, not references. Validate field by field; share state via server-owned snapshots or ids.</li>\n<li>Server Authority needs <code>Workspace.AuthorityMode = Server</code> plus the full bundle: NextGenerationReplication, PlayerScriptsUseInputActionSystem, deferred SignalBehavior, UseFixedSimulation, StreamingEnabled. Misprediction and rollback are normal (debug surface in full.md).</li>\n<li>Rate limits protect the server; validation still rejects invalid requests.</li>\n<li>Record suspicious behavior with thresholds; never punish one malformed packet.</li>\n<li>Edit-mode play: wrap the network layer so <code>RunContext:IsEdit()</code> gets a local loopback mock (full.md).</li>\n</ul>\n<p><strong>Need details?</strong> <code>references/full.md</code> has validation, throttling, and mock patterns.</p>\n","files":[{"path":"references/full.md","sizeBytes":24102,"isText":true},{"path":"SKILL.md","sizeBytes":2993,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
