Ambient Q-Regularity Excludes the Fitting-Conic Line as the Q Sector

Question

Entries 525--526 construct the canonical rank-one coefficient quotient

$$\mathcal L_{\rm fit}=G_{C_{\rm fit}}/G_{\rm lim}$$

on the fitting conic and prove that its rank and support do not change at the two nonsoft roots of

$$\mathcal Q|_{C_{\rm fit}}=u^3(8u^2-29u+8).$$

Could an induced connection on this line nevertheless carry intrinsic $\mathcal Q$-support?

Existing ambient theorem

Entry 169 derives the complete nine-master residue connection and proves that the final four-master block is closed. The whole connection is regular at every generic root of $\mathcal Q$, with

$$\operatorname{Res}_{\mathcal Q=0}\nabla=0, \qquad T_{\mathcal Q}=1.$$

Entries 207 and 209 further prove that the infinity-Gysin kernel

$$\mathcal A_{--}=\langle e_6,v_{\rm alg}\rangle$$

is connection-stable, its cyclic rank-one quotient is rationally trivial, and its $d\log\mathcal Q$ weight is zero.

No-go

Let $q$ be either nonsoft root of $8u^2-29u+8$. By Entry 526, both $G_{C_{\rm fit}}$ and $G_{\rm lim}$ have constant rank and unchanged pivot charts near $q$. Thus their quotient is locally free there. By Entry 169, the ambient connection matrix is regular at $q$.

If the ambient connection preserves the two bundles, restriction to the regular subbundle and passage to its locally free quotient cannot create intrinsic logarithmic monodromy at $q$. If it does not preserve them, no induced connection on $\mathcal L_{\rm fit}$ exists. A pole introduced by a singular choice of lift, splitting, or solution of

$$A r'=-A'r$$

is therefore apparent and has no invariant $\mathcal Q$-residue.

Hence

$$\boxed{ \mathcal L_{\rm fit}\text{ is not the intrinsic }\mathcal Q \text{-coefficient sector of the generic nine-master module.} }$$

This excludes both diagonal $\mathcal Q$-transport and a generic $\mathcal Q$-supported extension inside the closed final block.

Epistemic boundary

The conclusion is generic and de Rham. It does not exclude:

• a physical relative-chain local system not present in the absolute nine-master coefficient module;
• failure of extension across a discriminant or boundary compactification;
• an integral or deck-equivariant structure invisible to the rational connection;
• a $\mathcal Q$-sector elsewhere in the full 34-master system.

Corrected frontier

Do not fit a scalar connection to $\mathcal L_{\rm fit}$. The next admissible test is whether the physical integration-chain/Gysin realization introduces a relative local system whose forgetful image in the generic nine-master de Rham module is regular or zero. Absent such independently derived relative data, the fitting-conic line is an algebraic rank-jump quotient, not the published $\sqrt{\mathcal Q}$ sector.

Evidence

• Entry 169: exact nine-master connection and generic $\mathcal Q$-regularity;
• Entry 207: horizontal infinity-Gysin quotient and stable algebraic plane;
• Entry 209: rationally trivial cyclic algebraic quotient with zero $\mathcal Q$ weight;
• Entries 525--526: canonical conic quotient and non-Fitting behavior at the two nonsoft $\mathcal Q$-roots.
