SAMPLE — a real chain produced by this recorder's own code on a demo tenant, with synthetic demo actions. No customer data.
Verification runs server-side with the recorder's own pack verification code. Pasted packs are verified in memory and never stored. Rate-limited to keep the endpoint free for everyone.
What verification can and cannot prove
Verification recomputes the chain math, payload commitments and Merkle root and checks checkpoint consistency. HMAC signatures on signed objects are server-checkable only (the issuing server recomputes them).
A VERIFIED pack proves these records were not altered after they were written — it cannot prove an agent reported every action or that its reports were truthful.
Have something else?
- Raw ledger records instead of a pack? Paste them on /verify — that page verifies pasted records one link at a time.
- Prefer to check offline? The same math runs offline in the verifier kit that ships with evidence-pack exports.
