Conditional carrier/readout dynamics adapter

If a jointly continuous ambient-state segment stays in a registered carrier, is spatially closed, and the carrier has a continuous readout to the Circle, then the induced normalized Circle loops have equal endpoint winding. In addition, any globally continuous readout from a simply connected carrier sends every based loop to a nullhomotopic Circle loop. Thus nonzero winding in a Lohe-type consumer requires a separately registered non-simply-connected carrier or another explicit interface; no ODE existence or carrier-preservation result is assumed here.

What the Lean code literally says, in plain math · gpt-5.6-sol

This theorem is a conjunction. First, for every small topological state type, and every object consisting of a subset SSS, a continuous trajectory z:I×I→Statez:I\times I\to\mathrm{State}z:I×I→State satisfying z(t,x)∈Sz(t,x)\in Sz(t,x)∈S everywhere and z(t,1)=z(t,0)z(t,1)=z(t,0)z(t,1)=z(t,0) for every ttt, and a continuous readout r:S→Circler:S\to\mathrm{Circle}r:S→Circle, consider the normalized circle loop

x⟼r(z(t,x)) r(z(t,0))−1.x\longmapsto r(z(t,x))\,r(z(t,0))^{-1}.x⟼r(z(t,x))r(z(t,0))−1.

The floor-defined winding of this loop at t=0t=0t=0, computed from the endpoint of its real exponential-cover lift starting at 000, equals its winding at t=1t=1t=1. Second, for every small topological space XXX with a simply-connected-space instance, every continuous r:X→Circler:X\to\mathrm{Circle}r:X→Circle, every x∈Xx\in Xx∈X, and every path from xxx back to xxx, the path obtained by applying rrr is endpoint-preservingly homotopic to the constant path at r(x)r(x)r(x). The first assertion is conditional on an entire carrier-valued closed trajectory and readout already being supplied; it states no differential equation, existence, uniqueness, carrier invariance, openness, or simply connectedness of the carrier. For an empty state type there can be no square-valued trajectory, so the universal assertion over such segments is vacuous. The second assertion is vacuous when there is no base point xxx, and it concerns every supplied loop but supplies no loop-existence claim. The time and spatial comparisons use the endpoints 000 and 111, and the winding sign is inherited from the chosen exponential-cover lift and floor.
