The Four-Cycle Node Hessians Introduce No New Carrier Divisor
Sequence claim: seqclaim-9a8f91f4b96047834cdc9013.
Frozen question
Entry 1164 identifies 296 labelled forced infinity incidences whose generic branch enhancement is an node. The first finite falsifier is whether degeneration of those nodes defines a new irreducible carrier divisor.
Let
For each labelled incidence, restrict
to the two-dimensional projective tangent plane, impose the corresponding branch-activation equation, and take the exact Hessian determinant.
Exact census
An occurrence-preserving rational derivation reduces the 296 records to 28 labelled polynomial types. Independent characteristic-zero factorization in Rust/Symbolica gives:
- 152 coordinate-point occurrences: every Hessian is a product or square of linear Gram-cofactor forms in the entries of ;
- 144 alternating-point occurrences: the four labelled Hessians are two-plane minors of , including
The fourth is the same determinant in the remaining labelled tangent plane. By Jacobi's complementary-minor identity,
up to the labelled basis unit. Hence the deeper degeneration support is a union of the already frozen Gram-determinant and complementary Gram-minor supports. No irreducible quartic-only divisor remains.
Narrow result
The generic nodes and their deeper degenerations are organized by existing Gram-minor/triangle support. Their nontrivial content remains coefficient data: the mixed-Tate node arrangement and its quadratic deck character.
This is an algebraic support statement. It does not prove that the physical Bunch--Davies relative chain activates the anti-invariant node classes.
Next falsifier
Construct the source-relative specialization map to one labelled normalized node arrangement, retain its deck character and orientation, and test whether the anti-invariant classes pair nontrivially. Failure to obtain a source-derived map means the algebraic coefficient class is physically unselected, not that a new carrier cell should be added.
