#1426 closed honestly after 5 reviewer threads surfaced distinct correctness issues (same-replica dots collision, missing within-replica path, PN sign-collision falling to disjoint, Value-vs-full-state convergence, description drift). This row tracks the proper redesign: DVV.Sync chains + full-state equality + per-component sign constraints + within-replica out-of-order coverage + single-pass design (no incremental additions). P2 because the underlying math is already proven via Z3 + Lean; this is wrapper-layer coverage. The 14+ already-merged C3 properties substantially close the C3 → B grade upgrade.

Summary
Files B-0185 to track the proper Delta-CRDT property test redesign after #1426 closed honestly.
#1426's incremental approach (3 properties → 5 → reviewer feedback → close) didn't converge. The redesign needs:
P2 because underlying math is proven via Z3 + Lean; this is wrapper-layer coverage. The 14+ merged C3 properties substantially close the C3 → B grade upgrade.
