 ## Workflow Rules And Agents
 
 Meeting-specific automation lives in a local YAML file, not in committed personal rules. Rules can trigger on meeting creation, assistant-context state transitions, identified speakers, and transcript-line writes. They can add/remove attendees, set supported properties, add context, add projects, and rewrite a transcript line before persistence.
 
-The tray menu exposes the settings/logs assistant. It can edit workflow rules with validation, inspect logs and health/status, manage speaker identities and samples, run ASR diagnostics, and read/write scoped meeting/project artifacts through explicit tools.
