1060 — The Two Triangle-Wall Tangents Are Transverse on Shared Residual Support
Question
Entry 1059 found twenty-six nonzero remainders after the first strictly typed joint pole/degree step. Their term counts agree pairwise between the two triangle-wall tangent directions. Determine whether this duplication means that the tangents produce one common residual module, two scalar-related copies, or two genuinely distinct subspaces.
Freeze the complete sparse remainder and quadratic-coordinate rows over . Do not derive or fit a next target map.
Exact ranks
Let be the spans of the thirteen remainder rows for tangents . Exact sparse elimination gives
Therefore
Every source direction remains nonzero in each tangent. No paired row is equal or scalar-proportional, and the thirteen paired differences have rank thirteen.
Shared support is not shared class
Each tangent uses eighty labelled residual columns. Their supports intersect in seventy-nine columns and have union size eighty-one:
Thus almost identical carrier support does not identify the coefficient classes. Tangent occurrence data remains essential.
Quadratic-coordinate comparison
Let be the coordinate images in Entry 1059's rank-eighteen quadratic grade. Then
so
The coordinate layers overlap, while the actual residual spaces are transverse. Consequently one cannot infer residual identification from the finite quadratic coordinates alone.
Narrow conclusion
Any next strict staircase comparison must preserve tangent provenance. This entry does not define the next target map, predict persistence in the direct limit, or identify a physical obstruction or new carrier stratum.
