1063 — Quadratic Non-Descent Is a Canonical One-Dimensional Quotient

Question

Entry 1062 exhibited one relation $r$ with $C(r)=0$ and $\lambda(r)=1$. Determine whether this witness represents one isolated choice among several independent failures, or one canonical quotient of the complete quadratic relation space.

Exact relation-space sequence

For the twenty-six-dimensional labelled source space $S$, the quadratic coordinate map has rank eighteen:

$$C:S\longrightarrow C_{\rm quad}, \qquad \operatorname{rank}C=18.$$

Therefore

$$\dim\ker C=8.$$

Restriction of the graph functional to this kernel is nonzero and has one-dimensional image:

$$\operatorname{rank}(\lambda|_{\ker C})=1.$$

Its kernel consequently has dimension seven. The exact finite sequence is

$$0\longrightarrow \ker C\cap\ker\lambda \longrightarrow \ker C \overset{\lambda}{\longrightarrow} \mathbf F_{32003} \longrightarrow0,$$

with dimensions

$$7\longrightarrow8\longrightarrow1.$$

Thus the invariant obstruction is not the particular thirteen-probe vector printed in Entry 1062. It is the canonical quotient line

$$\boxed{ \ker C/(\ker C\cap\ker\lambda)\simeq\mathbf F_{32003}. }$$

Consequence

The pending $K_5$ adapter has one additional finite datum to transport beyond the quadratic associated grade. Any two explicit non-descent witnesses differing by one of the seven graph-zero relations represent the same quotient class.

This is still a finite modular coefficient statement. It does not establish characteristic-zero persistence, direct-limit survival, or physical activation.
