+## Transfer correction after the first run
+
+Run01 at 4dd764fa exposed a transfer bug in the unchanged-effective-size shortcut,
+not an SCC placement choice: moving children inward removed part of a parent's
+derived enclosure while the importer preserved its smaller authored size. The
+parent was therefore projected smaller than the explicitly requested geometry.
+Retain run01. Correct the importer with one simultaneous restoration of intended
+unchanged effective minima for noncollapsed nodes whose first projection is
+strictly smaller and at the exact intended position. Reject every other mismatch
+before restoration; require an exact second projection. Add identity, inward-child
+and inconsistent-plan regression checks. Then repeat the same corpus as run02.
+The SCC ordering, gaps, packing, routing and quality criteria remain unchanged;
+this is a correctness repair to faithfully execute the predeclared candidate.
