+A4A-R1 automatic verdict:
+SEGMENT_COMPRESSION_VALUE_PATH_NOT_QUALIFIED
+
+R2 correction:
+- no ConnectionNetwork.v_proj remote values
+- remote values live in the parent's native IAP activation space
+- remote propagation is combined with local propagated field before the frozen parent IAP gate/transform/norm/output projection
+- beta-zero exact parent identity required
+- Layer23 and Layer24 compared
+- VALUE_TOKEN / LINE_MEAN / SEGMENT_UNIFORM / SEGMENT_SOURCE oracle granularity compared
+- signed beta diagnostic
+- disjoint DEV and sealed OOD confirmation
+- no reader training
+- no model promotion
