SPE9 corner-point: 100-day comparison
A paired research run against OPM Flow covered 100 days and 400 accepted steps. Extending the paired case through control changes remains open.
Initial pressure investigation
An isolated endpoint candidate reduced the maximum initial pressure difference against OPM from 23.816 psi to 0.000240 psi. Day-10 dynamic differences remain.
These are distinct cases and research candidates; results do not establish production readiness. Evidence snapshot: October 2026.
