Single-Pair Literal Tor-Degree No-Go and the Target Enhancement Gate
Record
Date: 2026-08-15
Status: definitive scoped no-go for a Tor-faithful, fixed-shift realization of in the two ordinary literal entry143 corridor edges. The result does not exclude a nonfaithful map that kills or identifies Tor grades, nor an extraordinary target enhancement with a shifted edge costalk. No graph admission is claimed.
Exact single-pair census
For the ordered pair , the complementary positive marked corridor is . Its two exact literal edge supports are
Both are legal noncrossing faces and share the persistent label .
For a literal entry143 generator on an edge, and
Thus the four-state Boolean packet on one edge has graded profile
The two ordinary corridor edges have profile
The external object carries the same Boolean packet tensored with the independent conductor grades and . Its profile is
No fixed Gysin shift
A realization retaining both Tor grades and satisfying BC retractions must be a graded split injection on this packet. After a fixed Gysin shift , its source rank in every degree must therefore be no larger than the target rank.
The executable census tests every potentially relevant shift. No shift works. At , source rank three in degree three exceeds target rank two, and the degree-four source generator has no target. At , the lowest source generator falls into degree zero, where the literal corridor has no row. Larger shifts only move one of these endpoint failures.
Therefore no Tor-faithful fixed-shift correspondence
exists using only the two ordinary entry143 edge packets.
This is a grading/rank obstruction independent of coefficients, signs, denominators, or the earlier crossing-face obstruction.
Minimal target enhancement
Replace the two unshifted packets by an oriented extraordinary pair
Then
exactly matching the source. Tor degree zero maps to the ordinary edge and Tor degree one maps to the shifted extraordinary edge. No scalar or base section is inverted.
Literal entry143 contains no datum selecting one corridor edge for this shift. Moreover reflection exchanges the two edges. The enhancement must therefore include an oriented exchange isomorphism and its endpoint BC cell; choosing a shifted edge by hand would fit the desired map.
Rotation gives the same obstruction for the other two pairs. Until these three shifted corridor costalks and their reflection gluing are constructed, the 24-row literal realization, endpoint/ mapping fiber, , and its Bockstein remain undefined.
