Reference Solution

Use this directory after attempting or discussing the capstone starter.

• capstone.py contains the completed implementation.
• test_capstone.py contains the same checks supplied with the starter.
• evidence-record.md records the independently checked results and qualified conclusion.

From this directory, run:

python3 capstone.py
python3 capstone.py --report
python3 -m unittest -v

The implementation uses only Python’s standard library. The Decimal calculation is a reference for the declared nominal decimal inputs, while the four-corner envelope addresses deterministic input sensitivity. Neither check validates the physical sensor model.
