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.

  1. 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.

  2. 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.

  3. At carrier level the Ext-two obstruction vanishes. The lift space is nonempty and its components form an unpointed (\mathbb Z/2) torsor.

  4. 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

  1. Construct the integral endpoint connector on the canonical carrier roof.
  2. Compute its (\mathbb Z/2) reflection class.
  3. Establish uniqueness in the pointed two-extension category.
  4. Load that same butterfly with occurrence, multi-Rees, support, and PC/Cousin data.
  5. Compute the loaded Ext-two obstruction before imposing physical outputs.
  6. Assemble both endpoints and rotate through (D_3).
  7. Test Cut naturality at eight points.
  8. 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.
