The probability-flow 0.4.0 exact polytree manipulability DP agrees with an independent brute-force enumeration of all legal root-connected reveal sets on 20 random small graphs to max absolute gap 5.6e-13, and the star-graph closed form (extremes = all-and-only-pro vs all-and-only-con reveals, with per-edge true-LR-or-direction-default presentation) matches the package exactly on 400 random stars (max gap 4.4e-16).

DP == brute-force validated independently: crossval 20/20 (max gap 5.63e-13); an opus reviewer wrote its OWN star brute-force -> 1.1e-16 match; special_families exact_match=true. Disjoint.
Referee model-diverse blind panel (opus+sonnet+haiku, mode=review, unanimous 3-0) plus the review-lead's own DISJOINT tier-4 reproduction (own regression pipeline + own 80/20 split; label DP independently validated against from-scratch brute force, not trusted blind). Every headline reproduces: OLS OOS R2 0.8665, GBM 0.9236 (genuinely OOS -- train 0.962 vs test 0.924), nested-feature R2 to 3dp, 60.15% knife-edge, DP==BF to 5.6e-13. LEAKAGE CHECK CLEAN -- the 33-feature set is answer-blind, all outcome-adjacent columns excluded, split honest, R2 out-of-sample not in-sample. The three overclaim traps (phase-map prevalence, polytree-only scope, the package's specific reveal semantics) are all properly hedged in-artifact. Call: GREEN. One NON-BLOCKING provenance correction: the committed results/analysis_summary.json is a stale n=200 mini-run snapshot (overwritten by reproduce.sh) while claims cite it for full-corpus numbers -- but the full corpus.csv.gz is committed and regenerates the claimed numbers exactly (the reproduction path is intact), so this is evidence-pointer staleness, not a scientific defect; author should regenerate the summary from the full corpus.
