When a tirith content-security warning is present the approval backend forces allow_permanent=False and silently downgrades an "always" choice to session scope (the persistence loop in check_all_command_guards only honors "always" → permanent when no tirith finding exists). But the gateway notify payload that drives the TUI and the Electron desktop app never carried that flag, so both surfaces always rendered "Always allow" — offering a permanent allow the backend would quietly refuse to persist. Plumb allow_permanent end-to-end: - tools/approval.py: include `allow_permanent: not has_tirith` in the gateway approval_data the notify callback emits as `approval.request`. - ui-tui: thread `allowPermanent` through the event handler, gateway types, and ApprovalReq; ApprovalPrompt drops the "always" option (and renumbers the quick-pick keys) when it's false. - apps/desktop: thread `allow_permanent` through the gateway payload type, the per-session approval store, and the inline ApprovalBar, which now hides the "Always allow…" dropdown item when permanent allow is disallowed — reusing the existing DropdownMenu / confirm-Dialog UI. The desktop/TUI render path for approvals already landed in #38578 (the root cause of approvals not surfacing in the GUI); this completes the salvage of #37856 by carrying allow_permanent across both surfaces. #37856's original thread-local _block() approach is dropped: desktop/TUI approvals resolve via approval.respond → resolve_gateway_approval (the per-session queue), not the _block()/request_id correlation, so a worker-thread callback waiting on _block would never be released by the real UI. Tests: gateway notify payload carries allow_permanent (True without tirith, False with a tirith warning); ui-tui approvalAction reduced option set + event-handler allowPermanent propagation; desktop store round-trip + the ApprovalBar showing/hiding "Always allow".
