zack3d d849f71127 feat(patient): integrate brain/bladder/esophagus/stomach coupling
Introduce richer neuro-visceral coupling and signal integration across
organs to improve physiological realism:
- Add Brain, Esophagus, Bladder, Stomach, Spinal signal structs
- Couple bladder with spinal autonomics and brain state to drive
  parasympathetic/sympathetic/somatic outputs and thresholds
- Deliver esophageal bolus into stomach; update hiatal pressure and LES
  tone from stomach distension/acid/motility
- Move stomach emptying into intestines within patient update loop
- Replace spleen state penalty with immune activity-based adjustment
- Simplify gallbladder control using intestinal nutrient energy
- Refine heart autonomic tone using brain/spinal outputs
- Re-export BladderPhase, SleepStage, EsophagealStage

No breaking API changes.

medicallib_rust

MedicalSim core library rewrite in Rust.

  • Safe, minimal API for medical simulation primitives
  • Optional serde feature for serialization
  • Optional ffi feature to expose a stable C ABI (cdylib)

Build

  • Build: cargo build (tests: cargo test)
  • FFI build: cargo build --features ffi --release
  • Format/Lint: cargo fmt --all and cargo clippy -D warnings

Examples

  • Rust: cargo run --example usage and cargo run --example patient
  • C FFI: see examples/c/ffi_example.c, header in ffi/medicallib.h

FFI ABI

  • Opaque MLPatient handle
  • Functions: medicallib_bmi, ml_patient_new/free/update, ml_patient_summary, ml_patient_organ_summary
  • All allocated strings must be freed with ml_string_free

Version Matrix

  • Rust 1.70+ (Edition 2021)
  • OS: Linux, macOS, Windows (see GitHub Actions CI)

Docs

  • Architecture: ARCHITECTURE.md
  • Migration (C++ -> Rust): MIGRATION.md
  • C/C++ install: INSTALL.md

Packaging (binary distribution)

  • Linux/macOS: run ../scripts/package.sh [target-triple] from medicallib_rust/ (or make package).
  • Windows: run ..\scripts\package.ps1 [target-triple] from medicallib_rust\.
  • Artifacts are placed in medicallib_rust/dist/ as both .tar.gz (Unix) and .zip.

CI: GitHub + Gitea

  • GitHub Actions workflow: .github/workflows/ci.yml
  • Gitea Actions workflow: .gitea/workflows/ci.yml
