• Werbos's 1981 EIA Natural Gas Market Model report and Sandia's SAND-91-7095 are linked only by OSTI's single cataloging system, not by any shared history

• Bipartite check: Werbos's 1981 EIA Natural Gas Market Model documentation and OSTI's structured-metadata confirmation of SAND-91-7095's date — same database, not a shared idea

• A second, independent 2025 paper (Bolliger et al.) confirms differentiable MPM is a standing technique, closing a 26–42 year gap from Linnainmaa's algorithm and SAND-91-7095 to robotics applications

• ChainQueen's own reference list directly cites the Sulsky/Schreyer material-point-method lineage as MPM's origin — a traceable citation chain, not a coincidental resemblance

• The same problem needs no new tool — a nuclear-weapons-lab numerical method reached Disney's Frozen snow with no conceptual reinterpretation because penetration and snow are one continuum-mechanics problem; and the crisp 'Cold War weapons math' origin story was rounded at every checkable leg

• Capture: Does a genuine mechanism connect Linnainmaa's 1976 citation histogram and OSTI's structured-metadata confirmation of SAND-91-7095's date, or is the cosine-0.84 pairing a false friend?

• Does SAND-91-7095's full text confirm its abstract's mechanism description and pin down an exact 1991 vs. 1992 date?

• Did the Sulsky–Chen–Schreyer Material Point Method collaboration actually start in 1993, or does it trace back to an earlier Sandia report (SAND91-7095)?

• An earlier Sandia report, SAND-91-7095, predates the Material Point Method's 1993 founding papers by at least a year

• The Material Point Method's founding papers frame their motivation as penetration, impact, and large rotations together — not penetration alone
