C6 removed apes:tasks as a duplicate of the host session panel; in practice the two answer different questions (host panel = switch workspaces, plugin tab = who is running right now), so the tab is restored and the info layer goes back to five types.
tasks: live session list (current / running / subagent markers) + showInactive toggle via pluginSettings['apes:tasks']; messages: placeholder that states the host has no message feed yet; both get badge counters, and the whole layer now honours the visible gate (auto-collapse) so hidden tabs stop waking on session events.
zh/en/ja dictionaries in sync (AGENTS 5); wiki 02/03/07 reverted from three to five tabs; decision record in docs/plans/2026-10-11-apes-tab-revival.md.
