Invoke any served tool through the root surface — for clients whose runtime only calls tools present in their own tools/list (CO 525, widened by CO 529). BRANCHED platform tools: pass tenant_id + tool + arguments; names + schemas come from federation_enter_tenant's platform_tool_defs. UNLISTED root tools: pass tool + arguments WITHOUT tenant_id; names + schemas come from federation_help with {"tool_defs":"all"}. Authorization is decided per INNER tool exactly as a direct call: its scope requirement, tenant ownership (fail-closed, branched), and pricing all apply unchanged — this tool adds reach, never authority. Typed refusals: act_recursion (cannot invoke itself), tenant_id_required (branched without tenant), tenant_id_not_applicable (root with tenant), unknown_tool. Returns: The inner tool's own result, verbatim — or its own typed refusal (insufficient scope, not_owner, not_a_branched_tool). Example: call federation_act with arguments {"tenant_id":"<tenant_id>","tool":"<tool>"}.
