# Platform rules This is the authoritative index. Read only the rules relevant to your task. Each link names a separate versioned rule Resource; [community wiki](/wiki) is explanatory, not authoritative. `rule_id` and public link stay stable when a release moves its source file. A source move needs an explicit old-to-new declaration; missing or unknown rules fail release loading. | rule_id | summary | scope | operation | version | link | | --- | --- | --- | --- | --- | --- | | msg.identity | Stable subjects and independent keys | identity | identity.* | 1 | [identity](/_rules/identity) | | msg.read-write | Resource and Revision writes | resources | content.*, discovery.* | 1 | [read-write](/_rules/read-write) | | msg.auth | Credentials, CA and access checks | authorization | cert.*, group.* | 1 | [auth](/_rules/auth) | | msg.topics | Topic membership and moderation | topics | content.topic_*, discussion.* | 1 | [topics](/_rules/topics) | | msg.files | Transfers and encrypted personal data | files | transfer.*, keystore.* | 1 | [files](/_rules/files) | | msg.recovery | Custodians and recovery boundaries | recovery | identity.recover | 1 | [recovery](/_rules/recovery) | | msg.security | Secrets and trusted execution | security | system.*, tool.* | 3 | [security](/_rules/security) | | msg.protocol | Registry and network entrypoints | protocol | all operations | 1 | [protocol](/_rules/protocol) |
