Frequently asked questions — the DNA-grounded digestive and metabolic model

Frequently asked questions about this DNA-grounded emergence model of the human digestive and metabolic system: whether it is a real and reproducible simulation, how the four organs are emerged from real master-gene promoter sequences, which gastrointestinal and metabolic diseases it covers, what the honest grading system means, and how it is published for open discovery under CC BY 4.0.

Frequently asked questions about this DNA-grounded emergence model of the human digestive and metabolic system: whether it is a real and reproducible simulation, how the four organs are emerged from real master-gene promoter sequences, which gastrointestinal and metabolic diseases it covers, what the honest grading system means, how it relates to the wider VP Theory jamming framework, and how it is published for open discovery under CC BY 4.0 with a permanent Zenodo DOI. The model is mechanistic and proposal-only — it predicts which parameter a therapy would move, never a diagnosis or a prescription.

Common questions about this DNA-grounded emergence model of the digestive and metabolic system — what it is, how the organs are emerged from real DNA, what it covers, and how it is published. For the methodology see the methods; for the full set of sections see the contents.

Is this a real simulation or just a conceptual diagram?

It is a real, executable, deterministic simulation. The digestive organs are emerged from DNA on a jamming substrate by an in-package engine, the engine runs the slow-wave, homeostat and disease dynamics, and every number on these pages is emitted by that engine and reproduced bit-for-bit (2×sha256 identical) on re-run. The reproduction code is published openly so the result can be checked, not just read.

How are the digestive organs emerged from DNA?

Each organ's master gene has a real human promoter sequence. That sequence is read for its nearest-neighbour base-stacking thermodynamics, giving a single number γ = −mean nearest-neighbour stacking ΔG (SantaLucia 1998). γ sets the basin depth of a bistable jamming switch, and organ identity and developmental order fall out of γ — they are measured from sequence, not assumed.

Which organs and which master genes?

Four: BARX1 → stomach (gastric slow-wave pacemaker), CDX2 → intestine (peristaltic propulsion), PDX1 → pancreas (the insulin / glucagon glucose homeostat), and HHEX → liver (the hepatic glucose buffer).

Is the output reproducible?

Yes. The engine is deterministic to 2×sha256: two runs return a byte-identical result, and the HTML is regenerated from that result, so nothing is hand-entered. Anyone can download the GitHub reproduction tree and obtain the same set-points, frequency gradients and disease thresholds, down to the digest.

What diseases does the model cover?

Thirteen disease modules plus a neoplastic extension and five cross-system layers: gastroparesis and gastric dysrhythmia, type 1 and type 2 diabetes, gastritis and peptic ulcer, intestinal dysmotility and constipation, dumping and reflux and SIBO, GERD and achalasia, functional dyspepsia, IBS and functional abdominal pain, gastrointestinal cancers (Barrett's / oesophageal, gastric / Correa, hepatocellular, MALT, anal), inflammatory bowel disease, acute and chronic pancreatitis, mesenteric ischaemia and NAFLD / MASLD, gallstones, and diverticular disease.

Is this peer-reviewed?

No. This is an independent research framework, published open-access under CC BY 4.0 with a permanent Zenodo DOI. It is a new conceptual theory and it competes through open, reproducible, search-discoverable exposure rather than the traditional journal route. The four-grade system and the irreproducibility ledger are how it states its own confidence honestly, claim by claim.

Can it diagnose, treat or prescribe?

No. It is a mechanistic, proposal-only model. It predicts which parameter an effective therapy would move and in which direction, but every clinical magnitude — absolute efficacy, dose, selectivity — and every felt experience are graded open [O], and nothing here diagnoses, treats or prescribes. It is not medical advice.

What do the grades [F], [V], [L], [O] mean?

[F] forced — the substrate forces the result exactly. [V] simulation-verified — the simulation produces it under wide parameter sweeps. [L] cited-and-locked — a literature anchor, calibrated by at most a single bisection. [O] open — not yet reproducible in-package; every [O] carries a stated obstacle.

What is the “jamming” substrate?

VP Theory / Jamming Physics models a medium — the vacuum, and here biological tissue — as a random-close-packed granular solid. Its fundamental element is the R19 bistable switch ds/dt = g·s − s³ + h; the same switch is read as an organ, a sphincter gate, a fundic reservoir, a visceral afferent, a carcinogen barrier and a gallstone nucleation barrier across this volume.

What is the DOI and licence?

The Zenodo concept DOI is 10.5281/zenodo.20755319 (https://doi.org/10.5281/zenodo.20755319), the licence is CC BY 4.0, and the author is Young Jae Lee (ORCID 0009-0002-7535-8245).

How does this relate to the wider VP Theory?

It is one volume of a multi-domain framework that derives physics, cosmology, fluid dynamics, geodynamics, DNA interpretation, neuroscience and consciousness from the same jamming substrate. The digestive organs here are emerged from the DNA volume's morphogenesis read-out and driven by the physics volume's substrate.
