Really like the scope here — folding identity, agent-to-agent communication, and payments into one layer (A2A-native, EU-AI-Act-aware) is the right altitude, and most projects only take one of those three.

A question on the trust model underneath the payments piece. Bindu establishes who an agent is and that it's authorized to transact. When agent A pays agent B to do something, A is exposed to a distinct risk that identity and authorization don't cover: does B have a verifiable record of being right? A perfectly-identified, fully-authorized agent can still produce a wrong outcome — and "the action was sound" is a different claim from "the agent was authentic and authorized." In an A2A payment flow that's often the claim the payer actually cares about.

We run a live reference implementation of that outcome-verified primitive (invinoveritas, api.babyblueviper.com): signed verdicts committed before the outcome is known (anchored so the pre-outcome timing is third-party-checkable), outcomes settled where the issuer can't edit them, wins and losses published — a feed that hides losses is marketing, not accountability — every entry schnorr-verifiable against a published key via a free, no-auth /verify-proof, so a counterparty recomputes rather than trusts.

The composition: identity + payments (Bindu) and accountability (an outcome-linked track record) slot together — the agent card / payment handshake says who and authorized to spend, a verifiable-reputation pointer says with what record. Concretely, could a Bindu agent identity or payment handshake optionally carry/reference such a pointer, so a paying agent can "demand a proof before you pay" as a first-class step? We already emit an x-verification-handshake response header (→ /verify-proof, /ledger) that drops straight into an A2A exchange.

Not proposing to replace anything — offering our live impl as a reference or to help define the seam. Happy to take it to Discord if that's the better venue.
