Status: synthesis and formula objective. This entry records the conceptual consequence of entries 110–136. It introduces no new proof.
Revised object
The accumulated six-point evidence no longer supports treating the intrinsic NLSM primitive as an ordinary scalar function, subcomplex, strict projection, or unframed degree-one extension class. The strongest defensible formulation is
[ \boxed{ \mathsf J
\text{a loaded, endpoint-pointed, factorization-coherent butterfly} } ]
between the scalar support/Yoneda two-extension and the scalar PL–Tate/Cartier two-extension.
Before physical loading, the carrier comparison is the canonical roof
[ \mathcal R_{\rm AD}^{\rm car}: \qquad U\xleftarrow[\sim]{g_{\rm cap}}C_{\rm tag} \xrightarrow{m}T, \qquad m_1=R-R^2. ]
The physical half-object is conjecturally obtained by equipping this roof with endpoint connector 2-cells and then loading the same pointed object with occurrence, multi-Rees, positive-support, reciprocal/Borel–Moore, PC/Cousin, polarity, determinant, and physical-normal data.
Why this reformulation is forced
Four exact results delimit the possible object.
-
The unrestricted common-ring target is integrally and (D_3)-equivariantly contractible. Therefore ordinary coefficientwise Hom has zero cohomology. Any viable class must retain support, the based (Q)-leg, endpoint recollement, and extraordinary variance.
-
A comparison of two fixed two-extensions is a path object. Existence is controlled by their difference in (\operatorname{Ext}^2); once nonempty, choices form an (\operatorname{Ext}^1)-torsor. An Ext-one group alone is not the primitive.
-
At carrier level the Ext-two obstruction vanishes. The lift space is nonempty and its components form an unpointed (\mathbb Z/2) torsor.
-
The minimal strict Alexander projection is obstructed modulo three, while the full augmented cone has an integral affine rank-nine family of strict lifts. Relative AW/cap geometry canonically determines the common derived roof, but selects no member of that strict family.
Consequently neither a direct strict projection nor an arbitrary full-cone lift is intrinsic. The missing datum is a coherent pointing of the canonical roof.
Immediate theorem objective
Construct
[ \boxed{ \widehat{\mathcal R}{\rm AD}^{\rm car} \in \operatorname{Lift}{\operatorname{Arr}^2_{D_3}} \left( \mathcal R_{\rm AD}^{\rm car}; \mathbb E_F,\mathbb E_\triangle \right) } ]
as a pointed butterfly with:
- endpoint identities represented by connector homotopies rather than a strict degree-zero inverse;
- both cone-connector coherence equations;
- integral (D_3)-equivariance;
- no inversion of three;
- a derived, rather than imposed, reflection parity.
Only after this carrier pointing is constructed should it be loaded and the physical shadows evaluated:
[ \operatorname{gr}{\mathfrak c}^1G =K{\rm alt}\otimes L_{\rm pol}, \qquad \operatorname{gr}Q(\rho_G)(N{\rm road}) =+[q_\Sigma], \qquad \operatorname{Res}{x_3}G =\operatorname{pur}{x_3,\partial}^{\rm PC}. ]
These are tests of the loaded pointing, not inputs defining it.
Falsification boundary
The reformulation fails in its present form if any of the following occurs:
- no integral endpoint-compatible (D_3)-equivariant butterfly exists over the canonical roof;
- every pointing requires division by three;
- the two connector coherences cannot be satisfied simultaneously;
- loading destroys the carrier comparison or produces a nonzero loaded Ext-two obstruction;
- the resulting endpoint realization fails the already proved Cartier purity, marked (Q)-leg, or conductor/Tate shadows;
- the pointed system fails physical Cut naturality after rotation and assembly.
A noncanonical rank-nine strict lift is not evidence for the conjecture. A valid result must derive its pointing from scalar geometry.
Research order
- Construct the integral endpoint connector on the canonical carrier roof.
- Compute its (\mathbb Z/2) reflection class.
- Establish uniqueness in the pointed two-extension category.
- Load that same butterfly with occurrence, multi-Rees, support, and PC/Cousin data.
- Compute the loaded Ext-two obstruction before imposing physical outputs.
- Assemble both endpoints and rotate through (D_3).
- Test Cut naturality at eight points.
- Only then identify the global system with ((\operatorname{Pf}’A)^2) in CHY cohomology.
Conceptual consequence
The compact expression
[ I_{\rm scalar}^{-1}\operatorname{gr}R A{\rm scalar} ]
should now be read as decategorified notation for an extraordinary realization of a pointed scalar two-extension. The scalar master appears to create the NLSM primitive not by selecting a component of an amplitude, but by supplying a derived comparison whose support and endpoint coherences make factorization meaningful.
