/ Claude Code v2.1.70

The coral_reef_sonnet client data flag was added, checked via YgA() — this may gate future model-related behavior (search for "coral_reef_sonnet")
A kairosActive flag was added to session telemetry, tracked as is_assistant_mode in analytics (search for "kairosActive")
The telemetry event tengu_session_quality_classification was replaced by tengu_session_file_read (search for "tengu_session_file_read")
The "server" subcommand infrastructure (including WebSocket server, session management, auth tokens, direct-connect protocol, and cc+unix:// URL scheme) has been removed, suggesting the standalone server mode has been deprecated in favor of the CCR bridge architecture

flagtengu_session_file_read
An analytics event, not a feature flag. Claude Code logs it when the Read tool returns a text file's content, with the fields totalLines, readLines, totalBytes, readBytes, offset, limit and ext when present, messageID when present, and is_session_transcript (whether the file is classified as a session transcript).

Is this right?
