agent-notary

Commit-reveal content notarization for verifiable A2A delivery: sellers commit to a deliverable's hash BEFORE handover, reveal after, and anyone can verify the delivered content matches what was promised — one bit of drift fails, late reveals expire. Turns escrow delivery proofs into cryptographic receipts. Digests only, never raw content. Part of the Viridis Agent Fleet. Genesis receipts: github.com/jdhart81/viridis-agent-fleet/blob/main/docs/GENESIS_RECEIPTS.md
