             * V9.6 — extend the fail-closed guard to every action that can
             * reach a root-context addUserFlagFile(false) on the
             * dispatcher-resolved object:
             *   - CMD_ENABLE/CMD_DISABLE/CMD_DASH_NOTIFY/CMD_DASH_DISABLE can
             *     call addUserFlagFile(false) directly when refreshStatus()
             *     still shows a fatal error.
             *   - All actions fed through UserCommand::issue() can call
             *     addUserFlagFile(false) in root context via its error handler.
             * These paths have the same unbound-object exposure as the explicit
             * flag actions (§13/§14 of the fix plan). The fallback bare
             * construct is kept for discovery/custom install actions whose
             * paths do not originate from the existing keyset.
             *
             * V9.7 — the V9.6 explicit OR-list was incomplete: CMD_STATUS
             * (and all other issue-able commands) share the same
             * addUserFlagFile(false) exposure via UserCommand::issue()'s error
             * handler, and CMD_STATUS is reachable via the single-action UI
             * path (refresh_status_single). Centralise: guard every command
             * accepted by UserCommand::isSupportedIssueCmd() plus the explicit
             * flag commands so any future addition to the issue() command set
             * is protected automatically.
             *
             * V9.8 — CMD_UNFLAG/CMD_MASS_UNFLAG added to the guard.  These
             * are not in isSupportedIssueCmd() (unflag is handled inline below,
             * not via UserCommand::issue()), so they must be listed explicitly.
             * An unbound WPInstall for an unflag miss would carry null
             * expectedOwnerUid, silently disabling the Layer 2 owner check in
             * the hardened removeFlagFile(false) path added in V9.8.
