The planned 1.1.0 feature set is frozen. Useful changes fix a demonstrated bug, correct documentation, improve compatibility or strengthen a meaningful test. Discuss larger model changes before building.
Create a Python environment, install .[dev], then run python -m pytest -q and
ruff check src tests scripts. Describe the triggering case, resulting behaviour, tests and
assumption changes. Do not change expected financial values just to make a test pass.
Keep financial calculations in Python. Preserve exact accounting, causal information boundaries, strict journal verification and public/source labels. Avoid new dependencies without a concrete need. Do not commit personal runs, credentials, imported licensed datasets or local environments.
The MIT licence applies. Feature freeze and asset policy describe the release scope.
