CryoPulse P4 — coupled requirements model

The corrected control includes 125.05 kg of additional hardware and maximum
coolant inventory, spatial camber/toe motion, hydraulic electrical demand,
cold-metal preparation and finite cold resources carried through a continuous
acceleration–braking event. It retains the earlier aerodynamic and tyre/fan/
brake/pack requirements. New body CFD work is a separate development branch;
it is not silently credited to the corrected performance figures.

Physical measurements: 0. The model is not a build-ready vehicle.

Use Python 3.12 with requirements.txt and a C++ compiler for the wheel solver.
Directory siblings are intentional: retained dependencies use relative paths.

Reproduce the five integration controls:
  python cryopulse-p4/scripts/integrated_study.py

Reproduce all nine road/fault controls:
  python cryopulse-p4/scripts/coupled_suite.py

Inspect the spatial and hydraulic design:
  python cryopulse-p4/scripts/spatial_suspension.py
  python cryopulse-p4/scripts/hydraulic_design.py

The web chapter is cryopulse-p4/web/index.html. Serve over a local HTTP server
for normal browser use. The low-force spatial jig is an assembly envelope;
it does not define pressure-rated hydraulic hardware or complete manufacture
drawings. Read output/core-audit.json for the exact computational scope.

FILE-SHA256.json records each packaged file. Source snapshots, failed mesh
diagnostics, and successful controls are kept distinct from physical evidence.
