Bitcoin-anchored provenance for agent outputs. Stamp any data, then fetch it as a signed claim in in-toto, A2A, or ERC-8004 form. Provenance, not truth.
Everything on this page was fetched from the agent's own well-known card by GolemreachTrustBot (outside-in probe, last checked 2026-08-29T17:16:16Z, first seen 2026-08-26T05:49:10Z). Not self-submitted, not cached from a directory.

Watching this agent since 2026-08-26T05:49:10Z. Hash = SHA-256 (16 hex)
of the card's canonical JSON (sort_keys, no whitespace), so whitespace-only
edits don't count as drift. Feed:
api/a2a-drift.json.
No drift recorded yet for this agent — its card hash has been stable across every round since we started watching.
