+### Added
+- Free-text filter on every rule list page (`mode=edit_ruleset`), with or without host/service context: a search box above the list hides the rules (and folders left empty) whose row text doesn't contain the typed string, with a "N / total rules shown" counter. It is mutually exclusive with the "Relevant only" toggle: typing turns "Relevant only" off, and turning "Relevant only" on clears the search box.

+### Ruleset Free-Text Filter
+A search box above the rule list hides every rule whose row text (conditions, value, description…) doesn't contain the typed string (case-insensitive) and every folder left with no visible rule; a counter shows "N / total rules shown". It is mutually exclusive with "Relevant only": typing in the box turns "Relevant only" off, and turning "Relevant only" on clears the box.

 ### Extra Column with Host Actions
