Bounds, open questions, and retired claims

One source for the limits. The chain explains encoding, memory and behaviour — not subjective experience. Only one link is causal (capacity = theta over gamma, by tACS); the rest is model or direction. Consciousness is deferred to Mind. What is falsified and retired is the earlier physics by regime — the vortex field, the radiative EM far-field carrier, TIR optical-fibre conduction, energy = information, and DNA phase memory; EM as such is NOT retired — an electrical signal is electromagnetic, and its near-field (ephaptic) form is affirmed (§18–§19), with only its functional role open.

One source for the limits. The chain explains the computation of encoding, memory, and behaviour — not subjective experience. What is causal is one link (capacity = θ/γ, by tACS); the rest is model or direction; most absolute and causal quantification is open, and the decisive real-data validation — a behaviour-labelled memory task with artefact control — is still open. Consciousness, both the access question and the hard problem, is open and is deferred to the companion paper, Mind. The earlier physics is falsified and retired by regime — the vortex field, the radiative EM far-field carrier, TIR optical-fibre conduction, energy = information, and DNA phase memory. EM as such is NOT retired: an electrical signal is electromagnetic, and its near-field (ephaptic) form is affirmed (§18–§19) and load-bearing; only the far-field radiative carrier is retired, by measurement (radiated fraction ~10⁻¹⁵; conduction 0.5–120 m/s vs light ~2×10⁸ m/s). The single forbidden named entity is the “consciousness vortex field”.

What the chain does and does not do

Failure log (consolidated)

• Model ≠ proof: sufficiency in code is not truth in the brain; only the θ/γ capacity link reaches causal evidence (tACS).
• Energy ≠ information: energy is the price of switching (§2); equating the two is a category error (retired below).
• Binding is a conjunction, not a sum: synchrony makes a pointer, not an energy total or a carrier wave (§6).
• Real-data PAC is method-check, not task: the scalp PAC demonstration is a methods check on resting data, not a behaviour-labelled memory task.
• Direction ≠ magnitude: disease and motor reads match in sign; absolute Hz, gains, and latencies are not asserted.

Open register

• the decisive validation: a behaviour-labelled intracranial memory task with non-sinusoidal (harmonic) artefact control and phase-targeted causal stimulation — still open.
• most absolute and causal quantification across the chain (rates, latencies, concentrations, timescales, engram ratios).
• the access question of consciousness — robust bistable up/down dynamics plus report-labelled data — deferred to Mind.
• full clinical etiology (psychopathy, trauma, autism, Alzheimer): multifactorial; the circuit gives contributing mechanism only.
• the magnitude of any "ego-depletion" effect; the felt quale of a moral emotion.

Retired register (irreversible)

The following were physically falsified and are retired; they must not revive as evidence anywhere, under any name. The axon as an optical fibre / TIR waveguide — neural conduction is 0.5–120 m/s versus light at ~2×10⁸ m/s, a 10⁶–10⁸× mismatch, and the refractive-index arrangement is reversed. The EEG as an electromagnetic carrier's beat — tissue coherence length falls short by ~10⁹×; the real signal is synchronised synaptic current. Low-frequency sums producing high energy producing information — a linear sum stays low-frequency, and energy is not information (category error). A phase memory written in DNA — the real substrate is synaptic plasticity (§5). Forbidden renamings — the same entity under a new label — include the "vortex" as a field and any "consciousness vortex field". The re-grounded, functional parallel-eddy reading of thought belongs to Mind, where it is explicitly distinguished from this retired field.

Amendment — conduction-EM vs radiative-EM: what is retired, precisely

The retirement above must be read by regime, because an electrical signal is itself electromagnetic: the chemistry chapter unifies conduction (χ→0, longitudinal, a near-field) and radiation (χ→90°, transverse, a far-field) as one phenomenon. What is falsified and stays retired is the radiative, light-speed reading — the axon as a light-speed optical fibre (conduction is 0.5–120 m/s, confirmed), and the EEG as a coherent radiative carrier (the coherence shortfall). Three measurements forbid the far-field carrier: it does not radiate (the brain is sub-wavelength, radiated fraction ~10⁻¹⁵, §18), tissue is transparent to it at these wavelengths (head/skin-depth ~10⁻³, so it would pass through rather than reflect), and the 0.5–120 m/s conduction is ~10⁶× too slow for waveguided light. What is not retired, and is affirmed, is the near-field / conduction electric form of communication, which biology demonstrably uses: weakly-electric fish drive electric-organ discharges at distinct frequencies, read them with electroreceptors, and run a jamming-avoidance response that keeps the frequencies apart — frequency-division electrocommunication (verified in repro/neuro/_inherited/vp_electrocommunication.py: the field propagates to a receiver, channels multiplex with ~10⁻¹⁴ cross-talk, and the frequency gap is opened). The earlier blanket phrasing over-reached in lumping all of EM with the radiative carrier. For the human brain specifically there is no dedicated electric organ; and "weak" is true only of the scalp EEG (µV, volume-conducted), not of the local near-field, which §19 measures at the ephaptic threshold — derived ΔVm ≈ 0.27 mV (measured field 2.29 mV/mm × measured sensitivity 0.12) contained in the independently measured < 0.5 mV bound, a field-to-threshold ratio of order one, not ≪1. So the near-field is affirmed and non-negligible; what stays open — not asserted, not retired — is whether cognition functionally uses it, decided by a behaviour-labelled intracranial field cancel-vs-augment test carried to Mind. The single named entity that remains forbidden is the specific “consciousness vortex field”; the general field/ephaptic question is affirmed as real (near-field, §18–§19), with only its functional role open.

Consciousness → Mind

This paper deliberately stops at the computation. The access question (why some processing is reportable) and the hard problem (why any of it is felt) are not solved here; the one empirical attempt at an access marker did not robustly reproduce. Both are carried, openly, to the companion paper, Mind — which builds its functional account on this verified chain and keeps the retired field retired.
