# Spin(2,3) Global Path Selection v18: Both Surviving Routes Reached Their Construction Boundary

**Frozen:** 23 October 2026

The compactification and fixed-point branches have both been revisited using
all repository-local information.  The complete two-mode surrogate leaves
the pole coupling dependent on microscopic matrices.  The existing frozen
quantum packet is more complete than the earlier shorthand suggested, but it
already rejects the unchanged-spectrum local fundamental surface.

| ID | Path | State | Result or blocker |
|---|---|---|---|
| TM | Healthy axion--torsion surrogate | completed | pole coupling rotates continuously at fixed healthy spectrum |
| QP | Frozen local quantum packet | completed | \(\beta_C=11/(960\pi^2)\ne0\) normal to \(c_C=0\) |
| LF | Local unchanged-spectrum fixed point | rejected as fundamental | nonzero \(c_C\) adds an opposite-residue or tachyonic spin-two pole |
| SV | Stabilized torsional compactification | externally blocked | microscopic vacuum and \(K,M^2,g\) absent |
| NF | Enlarged/nonperturbative fixed point | externally blocked | theory space, full flow, reconstruction and IR trajectory absent |

No repository-local path remains unexecuted.  The two reopening conditions
are constructions rather than additional deductions: produce the stabilized
vacuum, or produce an enlarged nonperturbative definition with positive
reconstruction and matched infrared trajectory.
