Depth-Three Smith Profiles and Newton-Minor Geometry for Affine Hjelmslev–Radon Incidence

Oleksiy Babanskyy

Babanskyy reports every nonzero Smith factor of the integer affine point–line incidence matrix over Z/p³Z for every prime p. The profile reaches exponent p⁵ and has six multiplicities, with polynomial formulas for odd p and explicit p=2,3 rows. The new step resolves a q-Pascal common image through q-Newton minors and a cross-chart carry calculation.

What was already known

The earlier depth-two profile supplied part of the depth-three high tail; cyclic and complete-ideal results supplied other tools. They did not determine the full depth-three profile.

AI involvement AI-centered

GPT-5.6 Sol Codex supplied the depth-three reduction, q-Pascal analysis, minor argument, carry closure and formulas. Oleksiy Babanskyy directed the project, challenged derivations and selected the final claims.

Codex supplied the central new depth-three mechanism and formulas under human direction; the author checked and selected the final work.

Importance Notable

The result extends a specialized integral incidence invariant to depth three for all primes.

Limitations

Exact companion calculations cover the exceptional primes and selected formula controls. A complete independent check of the uniform q-Newton and carry argument is not documented.

Technical verification Partial

The repository documents exact exceptional-prime and symbolic formula checks, plus the author's iterative checks of derivations. These do not amount to a completed rigorous review of the uniform q-Newton and cross-chart proof for every prime.
