+The legacy 11-control setup predicate admits faces whose three corner valences
+are 5/5/5. The matrix construction describes one valence-5 corner and two
+valence-6 corners (5/6/6); that retained matrix mismatch remains a confirmed
+defect witness owned by D5. The classifier repair is owned separately by
+WP1.1a. The inventory records whether the checked-out
+`src/mesh/Mesh_setup_geometry.cpp` has total sentinel initialization for `d4`,
+`d7`, and `d8` and whether rejection and its throw precede publication to
+`face.adjacentVertices` and `face.oneRingVertices`; it does not treat an
+unmerged branch object as current-tree state. The classifier repair record
+neither quarantines the accepted all-Valence-5 fixture nor changes the matrix;
+D5 still governs those decisions.
