Immune & Hematologic Emergence (VP / Jamming Physics)

This volume emerges the thymus, spleen, bone-marrow haematopoiesis, and adaptive lymphoid tissue from one measured parameter γ as a population of R19 bistable switches, then derives clonal selection, inflammation, lineage order, memory, immunosurveillance, carcinogenesis, and four fundamental treatment levers. The ascending-γ ranking bone_marrow_hematopoiesis → spleen → thymus → lymphoid_adaptive is a code output; reading it as developmental order is interpretation, and building is open [O] (dna §RB). For comparison (observed, the haematopoietic sites succeed each other yolk sac → AGM/fetal liver → spleen and bone marrow, with the marrow colonised last (Tavian & Péault 2005), while RUNX1 is required from the first definitive haematopoietic cells in the AGM (North et al. 1999)). Research phase; concept DOI 10.5281/zenodo.20755280.

All quantities are measured inputs or model outputs under the no-tuning discipline; labels follow the reading rule above (code output, [L] measured/cited, [O] open with a stated obstacle). The four master-gene γ are byte-exact verified against the NCBI reference assembly (GRCh38.p14). Numbers are reproduced deterministically by repro/run_all.py.

• §1 Clonal Selection as a Saddle-Node Threshold — code output · interpretation
  Clonal selection = measured saddle-node at the spinodal; immunodominance, repertoire dominance, affinity maturation and antigenic imprinting all emerge from clonal competition.
• §2 Inflammation as Bistable Hysteresis — code output · interpretation
  Acute inflammation resolves, chronic latches: bistable hysteresis, loop width 2×spinodal.
• §3 Developmental Lineage Order from γ — code output · interpretation
  The ascending-γ ranking is a code output; reading it as developmental order is interpretation (building open [O], dna §RB). Observed: bone-marrow haematopoiesis is the last haematopoietic site, not the first (Tavian & Péault 2005).
• §4 Immune Memory as Barrier Persistence — code output · interpretation
  Memory = barrier-protected persistence; erase drive = spinodal; stability ranks by γ²/4.
• §5 Immunosurveillance: the Escape Seam — code output · interpretation
  Surveillance is a multiplicative cross-cutting seam: burden = crossing-rate × escape.
• §6 Carcinogen Dose–Response (Kramers) — code output · interpretation
  Carcinogens lower the barrier → convex Kramers dose–response diverging at the spinodal.
• §7 Fundamental Treatment Levers — code output · interpretation
  Four levers from the attractor landscape, all measured as trajectories; cytotoxic relapse is an explicit regrowth curve, and a cull + basin lever converts relapse into cure.
• §8 The Disease/Treatment Axis: Basin-Acting Cures vs Suppression-Only Relapse — code output · interpretation
  The disease/treatment axis: across six immune diseases, basin-acting cures (re-tolerization, induction, reconstitution, latch-break) are the durable class while drive-suppression-only relapses on withdrawal — one verdict, six self-contained pages. Direction/class only — not medical advice.
• §9 Autoimmunity: The Tolerance Break and Its Durable Re-Tolerization — code output · interpretation
  Autoimmunity is the R19 switch latched past the spinodal; a transient re-tolerization pulse cures durably, while sub-critical suppression only contains it and refills on withdrawal. Direction/class only — not medical advice.
• §10 Transplantation: Allo-Tolerance Induction vs Indefinite Immunosuppression — code output · interpretation
  Transplant tolerance is a negative saddle-node crossing: deep transient induction gives durable off-therapy tolerance, indefinite immunosuppression only contains rejection and relapses; the induction window closes as the alloresponse consolidates. Direction/class only — not medical advice.
• §11 Allergy: Dose-by-Repetition Sensitization, the Latch, and Controlled Desensitization — code output · interpretation
  Allergy is failed immune ignorance: a sub-threshold dose repeated sensitizes (N_crit falls as dose rises) and latches, while a controlled below-crossover protocol raises the threshold and desensitizes; an over-aggressive protocol sensitizes instead. Direction/class only — not medical advice.
• §12 Immunodeficiency Reconstitution: One Lever, Two Diseases — code output · interpretation
  Immunodeficiency is the collapse of one surveillance lever driving both opportunistic infection and immune escape; reconstitution is threshold-gated, so partial restoration below the coverage threshold is not a partial cure. Direction/class only — not medical advice.
• §13 Lineage-Targeted Autoimmune Cytopenia: The Attack Read Out on a Blood Count — code output · interpretation
  Autoimmune cytopenia is the attack read out on a blood count: re-tolerization restores output durably while suppression lets it re-collapse, and lineage support sets only the rate, not the destination. Direction/class only — not medical advice.
• §14 Systemic Inflammation: The Cytokine Latch and the Break Window — code output · interpretation
  Systemic inflammation past a critical insult is a self-sustaining cytokine latch holding itself ON after the trigger clears; it must be actively broken and the break is time-critical, with the coupling-off control flat. Direction/class only — not medical advice.
• §15 Repertoire Ageing and Durable Protection: Thymic Involution and the Optimal Re-Boost Interval — code output · interpretation
  Immune time on one substrate: thymic involution makes the repertoire drift (autoreactive escape rises, naive export falls) as the education window shrinks; and under a fixed booster budget the durable re-boost interval sits at the measured memory half-life (consistency: the script sets the horizon to 8 boosts × one half-life, so interval = half-life covers it exactly; the optimum is read on a 7-point grid) — too frequent wastes it, too spaced opens gaps. Direction/class only — not medical advice.
• §16 Cross-System Seams, Wired — code output · interpretation
  The immune volume is a hub: three seams on one byte-identical substrate wire it to its siblings — digestive's IBD mucosal latch IS this volume's T23 saddle-node and T24 suppressor complement, mind's HPA cortisol raises T24 suppression (sign only) while cytokine tone points one-way to mind's inflammatory mood contributor, and immune-escape multiplies every cancer kernel — with zero sibling imports. Direction/class only — not medical advice.
• §17 The Live Cross-Package Harness — code output · interpretation
  The seam layer takes the sibling identities on trust; an out-of-gate harness verifies them live — cross-volume substrate drift exactly 0, digestive's live IBD course reproducing this volume's T23/T24 thresholds, and mind's depression module carrying the HPA and inflammatory endpoints — while its digest hashes only the immune-side contract, byte-identical with or without siblings.
• §18 Circulatory & Musculoskeletal Spokes — consistency · interpretation
  Two inherited adjacencies become declared one-way-pointer spokes: leukocyte effector populations (rooted at bone-marrow haematopoiesis, RUNX1) traffic into the circulatory vasculature, and the same haematopoietic root is housed in the musculoskeletal marrow niche — both consume no sibling value, the firewall and the byte-identical engine hash hold, and the niche's shared-substrate-identity upgrade is named here as a candidate (subsequently live-verified and retired in §20).
• §19 Barrier-Surface Mucosal Immunity — consistency · interpretation
  The gut tolerance latch is barrier-surface-agnostic: across an antigen sweep the offset from a surface's own baseline is invariant at ±the spinodal(1.0), so the saddle-node identity generalises to any barrier surface (the gut is the one vendored point on the line). Respiratory (airway) is a named candidate; skin (epidermal) was LIVE substrate-verified in §21 against integumentary_vp_site v1.0.0 (drift 0 + reciprocal immune-seam handshake), with the identity staying immune-owned closed-form. Firewall and byte-identical engine hash kept. Direction/class only — not medical advice.
• §20 Musculoskeletal Seam: Live-Verified, Identity Retired — code output · interpretation
  The first live cross-package verification against a real sibling engine: with musculoskeletal_vp_site v0.7.0 present, cross-volume substrate drift is exactly 0 — so the marrow-niche pointer is LIVE-VERIFIED (the hematopoietic root and the MSK bone niche share one R19 substrate) — while the shared-substrate-identity candidate is RETIRED on live evidence: the niche is built by RUNX2 (spinodal 0.532), a different switch from the hematopoietic RUNX1 (0.585), so it houses hematopoiesis but is not the same switch (falsifier fired, pointer survives). An honest negative. Direction/class only — not medical advice.
• §21 Integumentary Barrier Seam: Live-Verified, Identity Holds as Closed-Form — code output · interpretation
  The second live cross-package verification, and a third distinct outcome: with integumentary_vp_site v1.0.0 present, substrate drift is 0 (the epidermal barrier and immune tolerance share one R19 substrate, the barrier surface real — TP63/KRT14), and the skin volume independently declares a reciprocal immune out-seam (a bidirectional handshake). The epidermal-tolerance identity stays immune-owned closed-form — confirmed-real-surface, not contradicted, but not engine-verified, since the skin defers the immune tolerance switch as an out-seam. Between the gut (verified) and the marrow niche (retired), the honest middle. Direction/class only — not medical advice.
