Framed the program around three first-author papers that deliberately extend written invitations from Jeff Anderson's published work: MER 2018, the under-development NN project in the Math 2BL S26 deliverables doc, and the 2024 anti-racist learner-centered objectives paper.",

The 'Modeling Bench' name is a working metaphor for the bench where Jeff's hands-on verification ethos gets practiced, not an institutional claim. Henry is principal author; Jeff is research mentor and second author on every paper.",

The colors exist to give a mentor a visual shortcut: any artifact in the lab carries its paper's color, so a reader can skim and know which paper a passage belongs to.",

Reason: with no walls, the k_p I + k_c A_3 structure falls out cleanly, and the eigenvalue spectrum of A_3 has an exact closed form (0, 1, 3) that gives us a teacher-free dimensionless prediction. The walls would add two more parameters and hide the clean result.",
