- lib/mitre.ts: shared types (MitreTactic, Technique, Subtechnique, MitreTag kind/id/external_id/name) + TanStack query keys. - components/MitreTagPicker.tsx: three-column controlled picker (tactic → technique → subtechnique), multi-select with chip-removal, autocomplete on each column, ARIA labels for screen readers. Returns MitreTag[] via value/onChange — drop-in for M5 template forms. - pages/MitrePage.tsx: status card (version, source URL, last_sync), admin- gated Trigger Sync button with success/error alerts, picker showcase, JSON preview of the current selection. - Layout adds MITRE nav link for any logged-in user; App.tsx adds the /mitre route under RequireAuth. HomePage roadmap bumped to next: M5 templates. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
