// TestApiCmd_PermissionError_DerivesFirstClassFields pins that when a Lark

// surfaced by `lark-cli api` lifts the diagnostic signals BuildAPIError
// consumed during classification into first-class wire fields
// (MissingScopes, LogID, ConsoleURL). The wire shape is the typed envelope
// — there is no raw-payload passthrough; new Lark diagnostic fields require
// a CLI release.
