Signal-Worker Boundary Confinement: A Corrected Ontology of Surface vs Bulk Transport

In the paper's words

The Signal-Worker (S-W) ontology — boson = signal (the delocalized field instruction), fermion = worker (the localized state that performs work) — is the QNFO corpus's proposed decomposition of the wave–particle duality fog. This paper delivers the red-team-hardened correction of that ontology's boundary-confinement reading, following a 3-slot adversarial audit (2026-08-14) that found 5 HARD defects. The correction is a taxonomy, not a renaming: only mode-confinement phenomena (topological insulators, the quantum Hall effect, and the non-Hermitian skin effect) confine fermionic transport to the material boundary; the Meissner effect and the AC skin effect expel the field/current density while the electrons (the "workers") continue to flow through the bulk.

The abstract, verbatim, and its opening sentence is the claim. Every line below is quoted from the text.

Numbers it reports

1. This is the literal "bulk → boundary" analog and the most on-point mode-confinement phenomenon for the ontology's vocabulary — and it is absent from the S-W corpus (a Completeness finding of the 2026-08-14 audit). [v0.3] The mechanism is now consolidated: the review literature [16] systematizes the modified non-Bloch bulk–boundary correspondence — spectral-winding and point-gap invariants replace the Hermitian Z₂/Chern classification — and the effect has been experimentally realized : an ultrafast topological non-Hermitian skin mode bound to a frequency-jump interface inside a gain-switched semiconductor laser, with direct intensity sampling of the skin modes (583 ± 16 fs FWHM) [17].

   from 3.5 Mode collapse (non-Hermitian skin effect) — TERRITORY (external, recent)

2. A superconductor actively expels the magnetic field: $B \approx 0$ in the bulk, with the field decaying over the London penetration depth ($\lambda _{L}$ ≈ 10–100 nm) [2].

   from 3.3 Field expulsion (Meissner effect) — TERRITORY

3. At 50/60 Hz the skin depth in copper is $\delta = \sqrt{2\rho/\omega\mu} \approx 9.2$ mm at 50 Hz and $\approx 8.4$ mm at 60 Hz (computed with $\rho = 1.678\times10^{-8}\ \Omega\text{m}$, $\mu = \mu_0$; BP-10 recompute 2026-08-17), so stranded wires below ~17 mm overall diameter conduct through essentially the full cross-section at mains frequency.

4. Quantum physics becomes explicit for surface-vs-bulk questions when a length scale approaches the Fermi wavelength ($\lambda_F \approx 0.46$ nm in copper) or the electron mean free path (~40 nm at room temperature): conductance quantization in integer multiples of the conductance quantum $G_0 = 2e^2/h$, ballistic transport, quantum confinement, and — genuinely quantum and genuinely boundary-localized — the topological surface states of §3.1, protected by bulk topology.

5. Nothing in this companion section changes the v0.1 taxonomy — it supplies the engineering and quantum-threshold context in which that taxonomy is applied.

How it is done

1. This is the literal "bulk → boundary" analog and the most on-point mode-confinement phenomenon for the ontology's vocabulary — and it is absent from the S-W corpus (a Completeness finding of the 2026-08-14 audit). [v0.3] The mechanism is now consolidated: the review literature [16] systematizes the modified non-Bloch bulk–boundary correspondence — spectral-winding and point-gap invariants replace the Hermitian Z₂/Chern classification — and the effect has been experimentally realized : an ultrafast topological non-Hermitian skin mode bound to a frequency-jump interface inside a gain-switched semiconductor laser, with direct intensity sampling of the skin modes (583 ± 16 fs FWHM) [17].

   from 3.5 Mode collapse (non-Hermitian skin effect) — TERRITORY (external, recent)

2. "boson = signal / fermion = worker" is a teleological gloss over the real boson/fermion distinction — the spin-statistics theorem (integer vs half-integer spin).

   from 6. Spin-Statistics Engagement

3. The corrected framing is a three-part statement : [TERRITORY — claimed identity; disconfirmed if a boundary-localized transport phenomenon falls outside all three classes (mode confinement / field expulsion / current-density redistribution), or if fermionic boundary transport is observed in a gapless-bulk geometry without bulk conduction] The boson/fermion distinction is the spin-statistics theorem (kinematic).

   from 9. The Corrected Signal-Worker Framing

What would falsify it

1. C1 is established physics (zero novelty weight); C2 is [RETRODICTION] until P1–P3 are tested; P1 is the only claim with a pre-registered experimental falsification path (platform: [17]).

   from 10. Falsifiability Register

2. Every claim carries an epistemic label and a falsifiability condition; the ontology itself is explicitly labeled an unconfirmed internal proposal.

   from Abstract

3. Premise-depth disclosure: the TERRITORY claims are as deep as the published physics they cite (bulk–boundary correspondence, spin-statistics, non-Hermitian topology); the MAP claims are derived from the ontology's own primitives (signal = delocalized field instruction, worker = localized state that performs work) and the imported corpus records [7–15]; the framework's premises END at the pre-registered falsifiability conditions P1–P3 (§10) — no deeper postulate is claimed. v0.2 (2026-08-16).

   from Abstract

Where the claim stops

1. It does not hold for the Meissner effect or the AC skin effect (field/current expulsion — electrons still flow through the bulk), and it does not hold for the corpus's own Weyl-semimetal substrate (conducting bulk with Fermi arcs).

   from 11. Conclusion

2. The mapping also fails on composite bosons (Cooper pairs — two fermions condensing into one boson) and self-conjugate particles (Majorana zero modes), and the corpus's own flagship substrate (TaAs, a Weyl semimetal with a gapless conducting bulk) contradicts the "worker excluded from the bulk" claim.

   from Abstract

3. Why a reader should care: the corrected taxonomy determines where "the worker is confined to the surface" is physically true (topological insulators, quantum Hall, non-Hermitian skin effect) and where it is a category error (Meissner, skin effect) — a distinction that decides which boundary phenomena can carry quantized transport and which cannot, with direct consequences for interpreting conductance measurements and for the corpus's superconductivity program.
