Dynamic Chirality-Induced Spin Selectivity as a Symmetry-Class Bridge
Book VI's parity slot and Paltiel et al.'s dynamic CISS mechanism
A PDF-backed response note reading Paltiel et al.'s dynamic CISS mechanism as a guarded symmetry-class bridge for Book VI's Parity Bridge slot.

Abstract
The note does not claim that Paltiel et al. validate Category τ, nor that Panta Rhei predicted their detailed molecular mechanism. Its narrower claim is a prior structural-slot record: Book VI had already articulated the need for a non-thermal, parity-sensitive amplification channel relevant to biological homochirality, and the Paltiel et al. mechanism appears to match that slot at the level of symmetry class and amplification role.
Anchor Paper and Context
Dynamic CISS mechanism
The anchor paper proposes a vibronic, time-even pseudoscalar spin-orbit coupling mechanism for enantiomer-distinguishing electron transport through chiral media.
Relation to this note: Read as an admissible candidate realization of the Parity Bridge amplification slot at the level of symmetry class and amplification role, not claimed as a mechanism predicted in detail.
Claim Boundary
Core Claim
Book VI's Parity Bridge records a prior structural slot for a non-thermal, parity-odd, time-even, weak-EM amplification channel between the weak-sector chirality seed and biological handedness; the Paltiel et al. dynamic CISS mechanism is an admissible candidate realization of that slot at the level of symmetry class and amplification role.
What This Note Does Not Claim
- It does not claim that Panta Rhei derived or predicted Paltiel et al.'s vibronic spin-orbit mechanism, molecular angular structure, or reported transport asymmetries.
- It does not claim that Paltiel et al. validate Category τ or Book VI.
- It does not establish that the Paltiel et al. mechanism is empirically final.
- It does not replace independent chemical, biophysical, or experimental validation.
Falsification and Challenge Surface
- Failure of the proposed operator to preserve the required parity/time/sign structure.
- Experimental refutation of dynamic CISS as the relevant amplification channel.
- Failure of the Book VI Parity Bridge interpretation under formal or semantic review.
