Counterexample CE-DS-NONCENTERED-SINGULAR-DESTINATION-001
What it falsifies
An exact global optimum over regular (nonsingular-nuisance) finite labelings is one-point exchange-stable under ANY feasibility convention, so DS18.2's finite stability step needs no convention. FALSE off the null set: on this support-minimal N=4 table from the named off-(L) law, both exact global regular optima reach the single nuisance-singular labeling by one admissible relocation whose DS11 pseudo-inverse value exceeds the regular optimum by exactly 1/96. The in-bin (DS9) convention -- singular destinations are infeasible -- is therefore load-bearing and must be named. This does not refute DS18, whose law makes such tables null.

How it was verified
Method: exhaustive.
Pure fractions.Fraction recomputation from the (X, Z) construction through the law; all six canonical K=3 partitions and every admissible relocation from both global regular optima checked by agenticresearch/py/audit_ds_noncentered_global_basin_transfer.py boundary and pinned in tests/test_research_claims.py.
