 into contiguous groups that minimize the heavier byte count. Ties prefer balanced
 file counts. Copy order, synchronization, complete byte readback and final
 nine-field witnesses are preserved; no extra worker or batch capacity is added.
+After synchronization and complete byte verification, the native helper asks the
+kernel to release clean cached pages for that restored file. Descriptor and path
+witnesses are still checked afterwards. This per-file streaming hint avoids
+retaining historical file contents in the fixed restore memory budget; it does
+not change file bytes, durability, limits or the live filesystem checks.
 Old configuration and maintenance receipts go into inactive
 `recovery/ID/history/`. The new boot's Sandbox preparation owns cgroup recreation.
 Unknown/nonempty targets and differing existing files are refused; partial restores
