Refined line-operator observable
The argument
Because the phase of a vortex-line operator linking an electric Wilson line distinguishes Higgs from confining regimes, a refined gauge-invariant form of the Aharonov-Bohm proposal survives, provided the undressed line-operator phase rather than the dressed-quasiparticle phase is taken as the observable that captures a test quark encircling a vortex.

The inference is valid but inherits the unsettled standing of its central premise: the argument stands or falls with the vortex-line operator phase distinguishing the regimes, which is now assessed as contested. The nonanalyticity calculation behind it is accepted by both camps in its 2+1-dimensional lattice setting, but whether that nonanalyticity marks a physical distinction turns on a disputed criterion, roughly whether gauge-invariant correlator behavior or finite-energy measurability is what counts, and the extension to the 3+1-dimensional theories the original proposal targeted remains open. The argument therefore preserves a serious, refined case for a sharp distinction without yet establishing one.

The inference is valid but carries two unresolved qualifications. It stands or falls with the vortex-line operator phase distinguishing the regimes, which is asserted through dualities and strong-coupling analysis and has not yet been confirmed by direct lattice measurement; and it requires reading that line-operator phase, rather than the dressed quasiparticle phase, as what a test quark encircling a vortex physically registers, which is the live point of contention with the continuity side.
