This directory is the installable package boundary for ZPE-Ink.

Prereqs: Python 3.11+ for the package, Rust toolchain for binding checks.

• zpe_ink/: Python package
• tests/: lightweight regression surface
• bindings/: source-verified bindings for WASM, Python-native, Swift, and C#
• scripts/: gate and handoff scripts imported from the original workspace

Install locally with:

python -m pip install -e './code[dev]'
python -m zpe_ink demo
python -m zpe_ink verify-roundtrip

Binding contract verification:

python code/scripts/verify_binding_contracts.py --repo-root .

Current technical truth:

• the installable release unit is the Python package under code/
• the Rust/WASM/Swift/C# bindings are repo-local source surfaces, not pip-installed artifacts
• binding drift is checked against docs/family/ZPINK_COMPATIBILITY_VECTOR.json

Source-verified means the source tree passed contract or build checks, not that a packaged runtime was shipped.
