Reject the entry as unsupported as written, without a return-review verdict or route refutation. The preserved join log records zero retained-table hits in each of eight families of 2^28 samples (2,147,483,648 total), and its table histogram sums to 39,568,684 entries. The source uses a Markov class-uniformity model and branch-probability pruning (BB=60) in addition to WMAX=10. These conditions do not establish the reported 95% actual-MD5 sparse-cluster upper bound. Its nominal -35.2 exponent reconstructs only a pointwise conditional retained-table estimator (-35.2470913 using rounded weights); discarded sparse mass and real-value conditioning remain unbounded. The depth-four source sample/model top probabilities are 2^-7.07 and 2^-7.00; they do not establish the entry's exactness assertion.

It verifies 10 files/24,581 bytes, 8 x 2^28 zero-hit samples, 39,568,684 table entries from the histogram and exact baseline identity.

Check threshold pruning, uniform-value model assumptions and the separation of zero sampled table hits from a real-MD5 success bound.
