+/**
+ * Regression test for #3578 — note captures marked as executed
+ *
+ * Note-classified captures were stuck in "resolved but not executed" limbo
+ * because executeTriageResolutions only handled inject/replan/defer. The fix
+ * adds a filter for classification === "note" and calls markCaptureExecuted
+ * for each matching capture.
+ *
+ * Structural verification test — reads source to confirm the note filter
+ * and markCaptureExecuted call exist.
