 ## Git Diffs
 
 Git Diff events (`kind: 1622`) represent changes between two commits within a Git repository, encapsulated as a unified diff. This event type is distinct from Git patches as it explicitly represents the state difference between two specific commits rather than modifications intended for direct application.
 
 Clients should render the event's `content` field as preformatted unified diff text (commonly displayed with diff highlighting).
