Agent Stability Engine (ASE)

Week 1-12 implementation for ASE core metrics, mutation stress testing, arbitration, contradiction analysis, taxonomy severity scoring, drift tracking, long-horizon stability, self-healing remediation, benchmark runner, regression gating, release/demo packaging, and CLI.

Build, Publish, Install (Python 3.11 Standard)

Use one interpreter path for the whole release sequence.

python3.11 -m venv .venv
source .venv/bin/activate
python -m pip install --upgrade pip build twine
python -m build
python -m twine upload dist/*

Install verification in a clean environment:

python3.11 -m venv .venv-install-check
source .venv-install-check/bin/activate
python -m pip install --upgrade pip
python -m pip install -U agent-stability-engine
ase --help
python -c "import agent_stability_engine; print(agent_stability_engine.__version__)"
