Systems

The systems/ lens documents cross-cutting subsystems that don't sit cleanly inside a single crate. Each page below traces a feature from the JS API through the Rust manager and runtime down to the OS where relevant.

Page	Covers
IPC and commands	The wire format, #[command] lifecycle, RuntimeAuthority, Channel, format_callback.
ACL and capabilities	Permissions, capabilities, scopes, identifiers; build-time resolution and runtime enforcement.
Event system	emit/listen, the global event bus, scoped events, plugin events.
Plugin system	The plugin trait, lifecycle, plugin store, mobile bridge, plugin authorship workflow.
Security and protocols	CSP injection, isolation pattern, custom protocols (tauri://, asset://), update verification.
Mobile	Android (Kotlin) + iOS (Swift) bridges, mobile entry points, mobile CLI subcommands.

For the runtime backend itself see crates/tauri-runtime-wry. For build-time integration see crates/tauri-build and crates/tauri-codegen.
