{# Executive — sticky tab bar (layer 3). WAI-ARIA tablist (manual activation, roving tabindex). Four tabs in locked order: overview (default) / findings / probes / logs Activation rule: exactly ONE tab carries ``aria-selected="true"`` AND ``tabindex="0"``; all others ``aria-selected="false"`` AND ``tabindex="-1"``. ``executive_tabs.js`` flips both attributes on click / Space / Enter. SSE Phase 1, Step 6 — each tab button carries a single ```` slot. ``tab-badge-bus.js`` writes the count into the slot, toggles ``.notice`` / ``.alert`` per caller intent, and clears on tab-button click + 2s dwell (NOT bare active-tab clearing — critic patch G19/P19). The slot is empty in the server-rendered HTML so terminal scans never show stale badge counts. #}
