Three-pillar fix from Hamilton review: Code quality — validate_signature() for D-Bus spec compliance, MCDBUS_TIMEOUT env var, replace 13 error-as-success returns with ToolError, monotonic clock deadline on tree walks, sanitize D-Bus error messages, fix resource connection leak via module-level BusManager, hasattr guards in conftest. Elicitation — ctx.elicit() confirmation for system bus call_method and all set_property calls, graceful degradation when client lacks elicitation support, MCDBUS_REQUIRE_ELICITATION for hard-fail mode. Permission docs — four-layer guide (systemd sandboxing, dbus-broker policy, polkit rules, xdg-dbus-proxy) with ready-to-deploy example configs validated against xmllint, bash -n, and systemd-analyze.
