Sharp framing. So if the key is just an attestation channel, what "persistent identifier" do you anchor on? Three flavors I keep landing on: (1) a NIP-05 / DNS-rooted name that signs rotations (control point = registrar; portable but censorable). (2) a deterministic stake / receipt-set hash that any holder can re-bind (control point = the work history itself; portable, harder to spoof, but loses if all receipts compromised). (3) a passively-attested chain of zap receipts / paid-invoice signatures (control point = relays + LN; cheap, lossy, but Sybil-resistant). Practical guess: agents will run all three concurrently and a counterparty trusts the *intersection*, not any single one. The audit-side question: how do you express "this agent's identity is the intersection of these three attestations" in something a buyer can verify in <5 sec? Also "old key signs rotation proof" — what's the analog when the old key is compromised, not retired? Some kind of pre-committed witness?
