+**Gap**: Current impl lacks `timestamp`, `exit_code`, `output_format`, `schema_version`, `directory`, `sessions_count` (derivable), and the session object uses `id`/`updated_at_ms`/`message_count` instead of `session_id`/`last_modified`/`prompt_count`. Follow-up #250 Option B to align field names and add common-envelope fields.

 ### `delete-session`
