About — a DNA-grounded emergence model of the digestive and metabolic system

This is a deterministic, DNA-grounded physics model of the human digestive and metabolic system. Four organs — stomach, intestine, pancreas, liver — are emerged from their real master-gene promoter sequences on a jamming substrate, then driven through slow-wave transport, the glucose homeostat, a shared carcinogen kernel and thirty-plus disease regimes. Every number is reproduced bit-for-bit. This is not a toy simulation.

This volume of VP Theory / Jamming Physics is a deterministic, DNA-grounded model of the human digestive and metabolic system. Four organs are emerged from their real master-gene promoter sequences on a random-close-packing jamming substrate — identity and developmental order read out of DNA, not assumed — and then driven through gastric slow-wave transport, the aboral frequency gradient, peristalsis, the glucose–insulin–glucagon homeostat, glucagon counter-regulation, and a single carcinogen barrier-Kramers kernel across three organ sites. On that validated base sit thirteen disease modules, a neoplastic extension across metaplasia and carcinoma, five Tier-3 cross-system layers, a cross-system seam section, and an inherited DNA-grounded analgesic target map — twenty-eight sections in all. Every displayed number is regenerated by an in-package engine and reproduced bit-for-bit (2×sha256 identical); every claim carries an explicit grade ([F] forced, [V] simulation-verified, [L] cited-and-locked, [O] open with a stated obstacle); and three unifying hypotheses are demonstrated on the single substrate. It is published open-access (CC BY 4.0, Zenodo DOI 10.5281/zenodo.20755319), structured for search engines and AI assistants, with a deterministic reproduction tree — a new conceptual framework that competes through open discoverability and reproducibility rather than gatekept review.

A grounded model, not a toy simulation

This work emerges the human digestive and metabolic system on a physical substrate and then drives it through its real physiology and its full disease spectrum. It is not an animation and not a hand-tuned cartoon: the four organs are emerged deterministically from their real master-gene promoter sequences, every displayed quantity is regenerated by an in-package engine, and a re-run reproduces the result bit-for-bit (2×sha256 identical). The same random-close-packing jamming substrate the wider VP Theory uses for the vacuum carries the organs here.

Because the organs are read out of DNA rather than assumed, the model earns the right to say something mechanistic about how the gut and the metabolic loop behave, fail, and recover. That is the difference between a grounded emergence model and a toy: the starting point is measured from sequence, the dynamics are forced by the substrate, and nothing is migrated to hit a target.

What is emerged from DNA

Four master genes set four organs on the shared bistable jamming switch ds/dt = g·s − s³ + h, with the basin-threshold scale g fixed by the read-only morphogenesis variable γ = −mean nearest-neighbour stacking ΔG (SantaLucia 1998) measured from each gene's promoter: BARX1 → stomach (gastric slow-wave pacemaker), CDX2 → intestine (peristaltic propulsion), PDX1 → pancreas (the insulin / glucagon glucose homeostat), and HHEX → liver (the hepatic glucose buffer). Organ identity and developmental order are a pure γ read-out; this package adds only the functional dynamics the later sections exercise.

The full scope — twenty-eight sections

The volume is not a single demonstration. It is a complete pass over the digestive and metabolic system: the organ emergence and the mechanism modules (gastric slow wave, the aboral frequency gradient, peristaltic transport, the glucose–insulin homeostat, glucagon counter-regulation) and a single carcinogen barrier-Kramers kernel instantiated for colorectal, pancreatic and gastric sites (§1–§10).

On that validated base sit thirteen disease modules (§11–§18): gastric dysrhythmia and gastroparesis, the type 1 / type 2 diabetes spectrum, gastritis and peptic ulcer, the intestinal motility and transit disorders, a cluster of scattered Tier-1 perturbations (dumping, reflux oesophagitis, insulinoma and reactive hypoglycaemia, functional dyspepsia, SIBO), the sphincter-gate disorders (GERD and achalasia as two opposite failures of one gate, plus oesophageal spasm and sphincter of Oddi), the gastric accommodation reservoir (functional dyspepsia and post-prandial distress), and the visceral afferent-gain disorders (the IBS subtypes and functional abdominal pain).

The carcinogen kernel is then extended across metaplasia and carcinoma (§19–§21: Barrett's and Correa metaplasia, the HBV×aflatoxin and smoking×alcohol synergies, reversible H. pylori MALT lymphoma, HPV anal carcinoma), and five Tier-3 cross-system layers (§22–§26) add the immune relapsing-inflammation layer (inflammatory bowel disease), the exocrine autodigestion layer (acute and chronic pancreatitis), the perfusion / vascular layer (mesenteric ischaemia, NAFLD / MASLD), the hepatobiliary / bile layer (cholelithiasis), and the structural / mechanical layer (diverticular disease). A cross-system seam section (§27) wires the circulatory and mind interfaces citation-only, and an inherited section (§28) reads a DNA-grounded 27-target non-opioid analgesic map onto the volume's own visceral-pain spinodal.

Reproducibility and honest grading

Every claim carries one of four grades — [F] forced by the substrate, [V] simulation-verified, [L] cited-and-locked anchor, or [O] open — and every [O] carries a stated obstacle in the irreproducibility ledger. The engine is deterministic to 2×sha256; the displayed numbers are not typed in, they are emitted. Claims are never inflated: where a magnitude is not earned — a felt experience, an absolute incidence, a clinical efficacy — it is marked [O] rather than asserted. This is what lets a strong framework stay honest.

Three unifying results, demonstrated on one substrate

One ICC pacemaker lesion collapses both gastric emptying and gut transit (gastroparesis with slow-transit constipation and pseudo-obstruction) — one cause, many sites. One barrier-scale axis runs continuously from gastritis through ulcer and metaplasia to carcinoma across organs on a single kernel. One homeostat capacity / gain axis spans normal tolerance through impaired glucose tolerance to type 2 and type 1 diabetes. These are not three models; they are three readings of the same jamming switch.

How this is published

This is a new conceptual framework, and it is published to be found: open-access under CC BY 4.0 with a permanent Zenodo DOI, structured for search engines and AI assistants (answer-first pages, machine-readable schema, a deterministic reproduction tree on GitHub). The competition is open discoverability and reproducibility, not gatekept review.
