algovoi-compliance-gate-lite 0.1.1

Open, content-addressed compliance-gate decisions bound to the pinned AlgoVoi substrate (ALLOW/REFER/DENY; no-PII; L1 frozen)

algovoi-compliance-gate-lite

The open, lite origination layer for AlgoVoi Compliance Gate. You bring a categorical screening verdict (ALLOW / REFER / DENY) from your own sanctions / PEP / AML provider; this binds it to a no-PII payer reference and to a pinned subject ref (a policy_bound_ref, settlement-action binding_ref, or retention_chain_ref) into a deterministic, recomputable gate_ref.

Because the verdict is bound to the subject by hash, a decision made under one policy snapshot does not recompute under a rotated policy; the verdict is provably tied to the policy that was in force. Additive over the frozen substrate (Apache-2.0):

payer_ref = "sha256:" + SHA-256(JCS({address, network}))      # address in, only the hash out
gate_ref  = "sha256:" + SHA-256(JCS({payer_ref, subject_ref, verdict}))

Lite vs commercial

	Lite (this package)	Compliance Gate v2
Licence	Apache-2.0, open	Commercial OEM
Verdict binding	content-addressed gate_ref	same, Falcon-1024 signed
Privacy proof	(none)	Proofs (zero-knowledge)
Verifier	recompute offline	maintained verifier

Pin lite, anchor a vector hash, carry the NOTICE → free v0 key; upgrade to v2 for post-quantum signing + Proofs.

Install & use

pip install algovoi-compliance-gate-lite

from algovoi_compliance_gate_lite import payer_ref, gate_ref, verify

payer = payer_ref("base", "0x…payer")                 # no PII: only sha256 comes out
# subject is any pinned ref, e.g. a policy_bound_ref from algovoi-policy-binding
ref = gate_ref("ALLOW", payer, "sha256:aaee2091…")     # bind verdict to payer + policy
verify(ref, "ALLOW", payer, "sha256:aaee2091…")        # True
verify(ref, "DENY",  payer, "sha256:aaee2091…")        # False (verdict tamper)

A verdict bound under policy P returns a different gate_ref if recomputed against the policy_bound_ref under a rotated P'; rotation is detectable. Invalid verdicts and malformed refs are rejected, not hashed.

Conformance

conformance/compliance_gate_lite_v1/: payer_ref + 3 positives (ALLOW/REFER/DENY), 5 negatives (verdict / policy-rotation / payer tamper; invalid verdict + malformed ref rejected), and 2 invariants. Verifier imports only stdlib + rfc8785:

pip install rfc8785
python conformance/compliance_gate_lite_v1/verify.py
