chio-eval-receipt-py

PyO3 binding that exposes chio-eval-receipt's bundle verifier to Python. It wraps a single function, verify_bundle_json, and adds no verification logic of its own. Builds as a cdylib Python extension module via maturin; excluded from the default Cargo workspace.

Responsibilities

• Wrap chio_eval_receipt::verify_bundle as a Python-callable function that raises ValueError instead of returning a Rust Result.
• Register the chio_eval_receipt_py PyO3 module and the one function it exposes.

Public API

• verify_bundle_json(bundle_json: str) -> str - production-verifies (verify_bundle, not fixture mode) a chio.eval-report.bundle.v1 JSON document and returns a summary string: bundle_id=... receipts=... signatures=... corpus_sha256=.... Raises ValueError on any verification failure.

Usage

import chio_eval_receipt_py

summary = chio_eval_receipt_py.verify_bundle_json(bundle_json_text)

Testing

Excluded from the default Cargo workspace (see the root Cargo.toml exclude list); build and test through maturin and pytest:

maturin develop
pytest tests/

tests/test_smoke.py checks that an invalid bundle document raises ValueError rather than returning a summary.
