+# Restack feature scoring onto merged package policy features
+
+## Accomplished
+
+- Replayed the prepared FeaturePolicy edge onto literal #9236 merge commit
+  `ffe5dbab5cebd3bc522d35f8ab472a4b7f604628`, excluding raster #9235.
+- Preserved merged PolicyFeature, adaptive policy, exact-branch proof,
+  subtraction replay, staged policy, complete source-pinned LogTables providers
+  and inventory, PNT examples, and current public interval registrations.
+- Confirmed that the exact combined Lake blob and narrow proof-only runtime
+  exemption remain unchanged by the merge-parent restack.
+
+## Current frontier
+
+PR #9237 is a direct-main FeaturePolicy edge. Raster #9235 and mixed-function
+#9238 and #9240 refs remain independent and unchanged.
+
+## Next step
+
+Run focused policy, controller, inventory, trust, freshness, and diff gates;
+then publish the direct-main PR head and monitor automatic CI.
+
+## Blockers
+
+None.
