Spin(2,3) Global Path Selection v29: M-Algebra Supergravity Passes Two Gates but Misses the Pole
Frozen: 23 October 2026
The higher-dimensional independent-connection double-back has been executed. M-algebra gauge supergravity combines local supersymmetry and a Lorentz connection in one gauge field, but its generic vacua are nonpropagating and its known four-dimensional dynamical reduction gives de Sitter general relativity, not the target axial torsion pole.
| ID | Path | State | Result or blocker |
|---|---|---|---|
| MA | Eleven-dimensional M-algebra gauge supergravity | completed | local SUSY plus independent connection established |
| GV | Generic vacuum carries target mode | rejected as selector | generic vacua are degenerate and nonpropagating |
| DR | Special reduction gives Spin((2,3)) (0^-) | rejected as selector | known result is positive-(Lambda) four-dimensional GR |
| FM | Gauge connection fixes fermion portal | rejected as selector | matter and normalized matching absent |
| NP | New four-gate torsionful SUSY parent | externally blocked | target vacuum, spectrum and matching absent |
| HD | Higher-spin/PGT dictionary | externally blocked | normalized holographic map absent |
| SV | Stabilized torsional compactification | externally blocked | microscopic vacuum data absent |
Known locally supersymmetric independent-connection constructions are now exhausted at the named four-dimensional PGT and eleven-dimensional M-algebra levels. Any continuation must construct and validate a new vacuum and action.
