Classical vortex atoms
The nineteenth-century programme did not derive real chemistry or spectroscopy, and stability became a central wound.
“Kelvin failed” and “Cosserat survived” are too coarse to be useful. HDR decomposes programmes into source-grounded propositions, dependencies, later evidence, failure modes and possible descendants.
One implementation can die while a structural idea remains mathematically available. Equally, a surviving mathematical structure does not inherit the abandoned ontology.

The abstract strategy that localized identity may reside in a persistent field configuration is separable from Kelvin’s literal atom model.
Modern vortices and topological defects make the generic class physically real without vindicating Kelvin’s atomic identifications.
The Cosserat move attaches orientation to local continuum structure. In a modern transposition the state can be written schematically as position plus an orientation field R(x,t) ∈ SO(3). That notation is modern; the structural idea is historical.
The reconstruction is not allowed to converge on CKC because CKC commissioned it. Branches may die, merge, become ordinary QFT in another language, or produce a descendant unlike the preferred model.
