mif-core
The metric and strategy qualification layer of the Metric Integrity Framework.
mif-core sits above the two canonical infrastructure projects:
mif-dqf → certifies data quality
mif-dal → assembles and hands off certified data
mif-core → qualifies metrics and strategies
This first increment defines explicit contracts and a deterministic offline catalogue. Tests are selected explicitly; no hidden one-size-fits-all protocol is applied.
Included test catalogue
The package currently ships six offline checks: DAL handoff readiness, signal shape, adaptive positive-return stability, return integrity, configurable rolling out-of-sample consistency, and prefix causality (look-ahead detection). They are deliberately small building blocks, not a complete profitability guarantee.
Development
python -m pip install -e '.[dev]'
python -m pytest
python -m build
The published distribution is named mif-foundation on PyPI. The
import package and command remain core and mif-core respectively; the
longer distribution name makes the PyPI project unambiguous.
Supported Python versions
The current release supports Python 3.11 and 3.12. Python 3.13 support is
deferred because the canonical mif-dal dependency currently requires a
NumPy version without a compatible Python 3.13 distribution.

An external strategy can implement StrategyAdapter and be certified against
an explicit list of tests. See examples/certify_strategy.py for an offline
example; production callers should supply the real DALHandoff from
mif-dal-en.
examples/certify_metric.py shows the corresponding metric contract.
See docs/API.md for the supported public surface.
See docs/ROADMAP.md for current limits and next phases.
See docs/PUBLISHING.md for the PyPI release path.
Status
Development implementation based on the documented MIF v5 architecture. The
architecture file contains a historical brainstorming version marker; the
provenance decision is recorded in docs/PROVENANCE.md.
Test
python3 -m unittest discover -s tests -v
