Re: Remaining questions for Zoom meeting 2026-10-21

Hi Francesco, Alan, Ren, Larry, Sean, AlgoVoi, all,

Francesco, your EU-recourse point and Alan's "trust is with the legal-person operator" converge on the same requirement, and I think it's the one this thread has been circling: what the protocol must make normative is not who is trustworthy — it's that trust must be verifiable.

Ren's original worry — hard-coding "what is safe" into the protocol makes it brittle — is right, and AlgoVoi's separation makes the boundary precise: a trust judgement is local and changing; delegated authority is attributable and bounded. Neither should be allowed to silently become the other. The one thing I'd add is that verifiability itself can be normative without becoming brittle: the protocol can require the form of a verifiable record — who granted, under which delegation, which evidence items are registered, who holds the verifier role — without ever declaring what a trustworthy agent looks like. The trust decision stays a runtime discovery; the auditability becomes a protocol obligation.

This maps directly onto the recourse chain:

Francesco's Art. 8(2) case — "who took the step, and under which delegation" is an evidence record. The merchant proves the order binds the consumer by producing a signed event, a delegation link (principal → agent), and the evidence that verified at the time. Recourse is only as strong as the records that survive.
Alan's zcaps/UCAN/VC comparison — a capability token proves entitlement ("may you act"); the evidence registry answers fitness ("should you act"). In the LGD lifecycle model those are two distinct layers: the grant for authorization, verified evidence (re-benchmark, release note, verifier role, validity window) for fit. A transition consumes both — exactly AlgoVoi's invariant that trust evidence informs policy but never becomes authority.
Larry's ATP conformance point — "support claims with reproducible evidence" is the same sentence. If the shared profile treated evidence presence as a checkable transition (like the status-read requirement Tymofii flagged in #192), the comparison stops being a diff of implementation choices and becomes a diff of evidence coverage.

Open question back to the thread: should the evidence requirement live in the ANP protocol itself, or in a separate conformance layer (like ATP's suite) so the wire stays thin and trust stays a discovery? My bias is the latter — it keeps Ren's "don't hard-code trust into the protocol" intact while making verifiability enforceable.
