+"""C-2 — Remove unused .cache/multi-agent-mux-monitor state directory creation.
+
+Verifies:
+  Y-1: --dry-run does not create .cache/multi-agent-mux-monitor
+  Y-2: --once --emit-diff does not create .cache/multi-agent-mux-monitor
+  Y-3: AGENT_SESSIONS_STATE_DIR does not create custom path or default path
+  Y-4: Reconcile executes normally and outputs valid drift JSON
+  Y-5: Existing pre-created .cache directory/files are unmolested during runtime
+  Y-6: Setting AGENT_SESSIONS_STATE_DIR emits deprecation warning on stderr without polluting stdout JSON
+  Y-7: Unset AGENT_SESSIONS_STATE_DIR is completely silent on stderr
+  Y-8: Empty .cache parent directory is reclaimed during uninstall
+  Y-9: Non-empty .cache directory is preserved during uninstall
+  Y-10: deploy/remove.sh correctly employs relative rmdir .cache
