The 'system' bullet was stale — it only mentioned the drop list
(init/result/rate_limit_event) and omitted the five specific handlers
added recently: plugin_install (muted note), commands_changed
(expandable details), compact_boundary (compact summary note),
thinking_tokens (in-place counter), and the generic catch-all.
Expand the bullet to cover the full dispatch shape, and add a
cross-reference to docs/terminal-rendering.md which has the
authoritative row taxonomy table and full dispatch walkthrough.
