Kelvin’s programme was richer than “spinning balls.”
Persistent vortical structure, topology and normal modes were explicit research commitments; the literal vortex-atom implementation did not mature into atomic physics.
The programme separates historical survival, mathematical availability, physical realization elsewhere, and CKC-specific derivation. Similarity is cheap; numerical recovery and discriminating prediction are expensive.

A continuum can possess independent rotational structure and generalized stresses beyond displacement-only Cauchy mechanics.
Known condensed matter supports quasiparticles, vortices, order-parameter topology and effective low-energy field structures.
The classical sphere is not rescued by renaming its rotation “vorticity.”
The literal nineteenth-century identification is not the hypothesis under reconstruction.
The topology of rotations is a clue and constraint, not a derivation of electron ontology.
Write the simplest explicit energy functional for a Cosserat-like superfluid continuum capable of localized rotational structure. Determine whether the candidate defects possess genuine topological or energetic stability before asking them to imitate spin.
