agent-identity-registry
Verifiable agent identity (content-addressed DIDs) + capability discovery — the passport and directory of the A2A economy. Part of the Viridis Agent Fleet: identity, trust, escrow, metering, arbitration, covenant, provenance, compute-carbon ledger, offsets — plus sellable services running on them. Durable state, machine-checkable invariants, free to call. Genesis receipts: github.com/jdhart81/viridis-agent-fleet/blob/main/docs/GENESIS_RECEIPTS.md
