CRYOPULSE P4.7 EFFICIENCY RESEARCH / PHYSICAL MEASUREMENTS: 0

Conditional operating-policy study. No measured fuel, nitrogen supply or driving data.
Use the same Python 3.12 numpy/scipy/CoolProp environment as P4.6, plus matplotlib.
Extract this folder beside the complete immutable P4.4, corrected P4.5 and P4.6 sources.
P4.6 source: https://cryopulse.org/research/ecosystem/files/CryoPulse-P4.6-development.zip
P4.6 SHA256: 7d5befaa16496dc5e0498d7e771d842d95034879a7a519b63d22f5f68c8ef83a
P4.4: https://cryopulse.org/research/p44/CryoPulse-P4.4-model-and-results.zip
P4.5: https://cryopulse.org/research/airflow/files/CryoPulse-airflow-diagnostic-v2.zip
Follow P4.6's START-HERE for its dependent source hashes and environment.

From the common parent, after rebuilding P4.6's installed maps if needed:
python cryopulse-p47/scripts/efficiency_sweep.py
python cryopulse-p47/scripts/verify_cold_mode.py
python cryopulse-p47/scripts/build_efficiency_review.py

Existing raw cases are reused after the source/plan checks. Remove only the P4.7
output trial files in an isolated extracted copy to recompute all trials from scratch.
Never remove the required published P4.6 control outputs.
The finer duct CFD work is separate and has received no vehicle-performance credit.
