Source presentation; provider and runtime readback are separate gates. IMMUNE is the read-only verification plane. Energy remains UNAVAILABLE; Λ remains Conjecture 1. A signature proves scoped integrity and origin; it does not prove accuracy, safety, performance, compliance, or authorization.

This card is generated by SZL Surface Foundry from the reviewed source contract. The generation receipt binds its copy and SVG; it does not attest live publication or independent product verification.

At that exact brand revision, run PYTHONPATH=src python -m szl_brand.surface /path/to/README.surface.json --output /tmp/szl-readme-card. Copy the generated SVG to readme-surface-card.svg and the receipt to README.surface-receipt.json; update only the v3 managed block and preserve the surrounding source bytes.

NEXUS MK-II

A playable research instrument, not another dashboard. NEXUS combines a browser-local Web Audio synthesizer, sequencer, patchbay, tape deck and phosphor CRT with deterministic analog-dynamics references in TypeScript and Python. The Grok-origin visual language is preserved; SZL source binding, tests and fail-closed evidence boundaries make the public projection reproducible.

Holographic analog computer. Six programs. Optical core. Analog neuromorphic. Ouroboros. Five organs. Phosphor CRT.

Frontier is not a preset dump — it is a running analog computer. Six integrator programs (Lorenz, harmonic oscillator, van der Pol, Duffing, Lotka–Volterra, NEMO analog neuromorphic) with IC / OP / HALT / REP. A two-beam optical analog inner product reconstructs on the holographic CRT and folds the voice. The function generator is a rise/fall triangle. Those voltages drive voice cutoff, pan, fold, tape delay, the grid pen, and the hologram.

The SZL kernel is analog physics, not a seventh module. Ouroboros taxes amplitude over eight bounded bars. Eight falsifiable invariants hash the analog receipt chain. Five organs (YACHAY, YUYAY, YAWAR, OTel, KHIPU) fail-close the VCA. Hatun probes stay LIVE or honestly UNAVAILABLE. Energy is UNAVAILABLE — never a fabricated joule. Λ is advisory. Conjecture 1 remains OPEN.

Three aggregators run on the same 13 analog voltages: Λw (F19 weighted geometric mean), Λs (symmetric 1/13, A5 permutation invariance), Λe (Egyptian Horus-Eye 1/2+…+1/64 = 63/64, Theorem U). maxAgg is the live counterexample — same vector, different score. Disagreement is analog, not a mute. Unconditional uniqueness stays OPEN and false as stated.

Inspired by analog computing practice (THE ANALOG THING, CRT holograms, modular patchbays) — not a dashboard, not a generative-audio model.

Module	Role
The Grid	16×8 phosphor matrix. Write cells. Analog pen tracks analog X×Y.
Oscilloscope	Y-T, X-Y, FFT, HOLO. Hologram is a two-beam optical analog plus five organ nodes and a WILLAY conscience ring.
Tape Deck	Stereo echo with wow, flutter, saturation. Analog Z modulates delay time. Bounce dumps eight seconds.
Patchbay	Sources include ANLG and FUNC. Drag source → dest. Click a cable to pull it.
Sequencer	16-step clock, Euclidean hits, swing, probability, arp. Ouroboros closes the loop at eight bars in Frontier.
Voice	Morph VCO, ladder-ish VCF, ADSR, unison, FM, folder, LFO, S&H, ring. Analog computer: LRNZ / HARM / VDP / DFFG / LTKA / NEMO, IC / OP / HALT / REP, Rate, Chaos, Drive. Live analog circuits: integrator, summer, multiplier, inverter, comparator, correlator. Analog Schmitt. Hybrid seq→S&H. Λ and energy UNAVAILABLE on the panel.

Default chain: VCO → VCF → DELAY → VCA → OUT. Scope taps the master bus.

Frontier patch: ANLG → VCF, FUNC → PAN, S&H → VCF. ANLG is the analog computer jack (integrator + multiplier + analog correlator + WILLAY reconstruct). Analog Schmitt clocks S&H from the correlator. In Frontier the sequencer samples the correlator (hybrid ADC). REP accent loads analog IC (hybrid IC). F19: a DOWN organ mutes the VCA. Master cannot compensate.

Analog computer

Mode	What it does
IC	Hold initial conditions. Seed voltages freeze.
OP	Operate. Integrators run. The attractor lives.
HALT	Freeze the current state. CV stays put.
REP	Repetitive operation. Reseed the attractor on a period set by Rate.

Program	What it integrates
LRNZ	Lorenz (σ, ρ, β). Three integrators.
HARM	Harmonic oscillator. Two integrators, ω from Chaos.
VDP	van der Pol. Nonlinear damping μ from Chaos.
DFFG	Duffing. Cubic restoring + driven cosine.
LTKA	Lotka–Volterra. Prey/predator stay positive.
NEMO	Analog anatomy + second brain. Five AdEx organ-neurons: YACHAY cognition, YUYAY pacemaker, YAWAR traveling wave, OTel optical write, KHIPU bound. WILLAY optical ring is conscience — not a sixth organ. Tsodyks–Markram analog STP, three-factor optical STDP. Not a physical chip.

Coefficient pots: Chaos maps onto the program’s analog coefficient. Rate is computer time (BrainScaleS-style acceleration on NEMO). Drive is injected current on YACHAY (cognition), YUYAY pacemaker If, and the analog neuromodulator (third factor) — not dopamine. YAWAR is the traveling analog wave around the organ ring. Optical analog: object beam (X,Y) interferes with reference beam (FG,Z). Reconstruction is WILLAY, the second brain, and folds the voice. NEMO uses the same optical inner product as a photonic synapse and as analog STDP eligibility. Analog correlator is a leaky product of X×Y (BrainScaleS analog-correlator job). Analog Schmitt is the analog event detector. Hybrid: the sequencer is the digital half — it samples the correlator into S&H, and a REP accent writes analog IC. Energy stays UNAVAILABLE — never a fabricated pJ/spike.

Inspired by analog computing practice (THE ANALOG THING, EAI hybrid IC/OP/HOLD, CRT holograms, modular patchbays) and analog neuromorphic literature (Izhikevich 2003; Brette & Gerstner AdEx 2005; BrainScaleS-2 analog correlators; Mead analog VLSI) — original analog-computer-native math, not a Loihi/BrainScaleS/THAT emulator, not a dashboard, not a generative-audio model.

Kernel as voltages

Organ	Quechua	Formulas	Analog face
BRAIN	YACHAY	F1	Function generator. Read-only cortex.
HEART	YUYAY	F4 F11	Λw weighted geometric mean. Zero axis fail-closes. Λs / Λe / maxAgg on the same 13 voltages. Disagreement is analog. Uniqueness OPEN.
CIRCULATORY	YAWAR	F7 F22	SHA-256 analog receipt chain.
NERVOUS	OTel	F12	Loop-tax. Energy UNAVAILABLE. Hatun probe.
SKELETON	KHIPU	F18 F19	Locked-8. CHECKED ≠ Lean PROVEN @ c7c0ba17.

WILLAY is conscience, not a sixth organ — the hologram ring. Analog anatomy lives on NEMO: YACHAY cognition, YUYAY pacemaker, YAWAR traveling wave, OTel optical write, KHIPU bound. Locked-proven exactly eight: F1 F4 F7 F11 F12 F18 F19 F22. ed25519 and flywheel stay UNAVAILABLE without a key or samples.

Run it

Launch Frontier — unlocks Web Audio and boots the holographic analog computer.

Then play the keys, patch ANLG into VCF, watch HOLO, and throw Chaos.

• Z–M piano (shift = octave)
• Space run / stop sequencer
• P cycle scope Y-T / X-Y / FFT / HOLO; Tab remains standard keyboard navigation
• F Frontier · Shift-F disengage · F again reseeds the loop
• Voice: IC / OP / HALT / REP
• Scenes F1–F22 on the header (shift-click stores)
• Esc panic (all notes off)
• ? shortcuts

Patterns, patches, tape, and voice settings persist in IndexedDB on the machine that played them. No account is required. Audio execution and user state remain browser-local; the canonical Space serves the prerendered workstation and its source-bound build identity from a Python standard-library runtime (space/app_server.py), while the Python engine remains the deterministic reference and parity implementation.

Source and runtime authority

• Source of truth: szl-holdings/nexus.
• Canonical organization Space target: SZLHOLDINGS/nexus, published only by the central exact-source workflow. A source merge alone does not establish that the Space exists, is current, or is running.
• Origin preview: betterwithage/nexus. Preserve it as the Grok-origin preview until the organization Space has immutable source readback and browser qualification; it is not the canonical publisher or proof authority.
• IMMUNE verification plane: SZLHOLDINGS/immune/nexus.html remains a read-only replay/verification surface, not a replacement for the playable workstation.
• NEXUS is a distinctive creative-research showcase inside SZL Holdings, not a fourth commercial flagship and not a production certificate for A11oy.
