AlgoVoi Policy Binding: now on PyPI and npm (Apache-2.0)

[chopmob-cloud]

What it is. Policy Binding is an additive, Apache-2.0 layer for the AlgoVoi substrate. It binds a content-addressed snapshot of the policy in force to an existing AlgoVoi reference (a settlement-action binding, or a retention-chain entry), so a decision is verifiable against the exact policy version that admitted it, and a policy change is detectable by recomputation. It is offline-verifiable: any party recomputes the binding with SHA-256 over JCS (RFC 8785) canonical bytes, with no operator trust required. The canonicalisation base and the underlying binding and chain are unchanged; this layer only references them by hash.

It works across v0 and v1 (it binds over retention-chain v0 and v1, and the settlement-action binding), and it ships natively in Substrate 2.

Install. Pin the version, preserve the NOTICE (an Apache-2.0 requirement), and run the conformance suite.

# Python
pip install algovoi-policy-binding==0.1.0

# Node
npm install @algovoi/policy-binding@0.1.0

Both packages are byte-for-byte identical and cross-checked against the public conformance vectors. Pin the exact version, not a range.

• PyPI: https://pypi.org/project/algovoi-policy-binding/0.1.0/
• npm: https://www.npmjs.com/package/@algovoi/policy-binding
• Conformance vectors: https://github.com/chopmob-cloud/algovoi-jcs-conformance-vectors

Licence. Apache-2.0. A NOTICE file ships with each package and must be preserved in any distribution (Apache-2.0 section 4(d)).

For L2 developers across the ecosystem. AlgoVoi maintains the L1 canonicalisation base, stable and cross-validated across eight independent implementations, openly under Apache-2.0, as a foundation the whole ecosystem can build on. Policy Binding is how we extend it: never by changing the base, always by adding layers on top that import the base by hash. That keeps every layer interoperable and makes attribution structural. We want L2 builders to build on this. Pin the version, keep the NOTICE, and your work composes cleanly with ours as the base evolves.
