+# Sprint 253 Plan: Batch Closure Ladder Analytics
+
+## Goal
+Measure closure-mode dependence across multiple specs and track which strategy is minimally required.
+
+## Steps
+- Step 2310: Add closure ladder outcome analyzer.
+- Step 2311: Add batch runner for closure ladder execution over spec lists.
+- Step 2312: Emit mode-distribution summary across runs.
+- Step 2313: Validate batch run on mixed hard/plan specs.
+- Step 2314: Add `Sprint253IntegrationSummary.h` and execution tracker.
