Was this agent session actually what it claims?

Drop a captured AI-agent ledger below. This page recomputes the hash‑chain, the causal DAG, every per-event Ed25519 signature, and any external anchors — entirely on your machine, using the same conformance-tested verifier shipped in Rust, Python, and this JavaScript. Zero trust in the tool that produced it.

Drop a ledger.jsonl or paste the events below — one JSON object per line, or a JSON array

What a green verdict proves

The events are hash-chained intact — no edit, deletion, insertion, or reorder.
They form a well-formed causal DAG (every triggered_by is strictly earlier).
If a signer key is pinned: the holder of that key attests to each event.
If anchors are present: the tip matches an externally-witnessed record.

What it does not prove

When it happened — local timestamps aren't a trusted time source (use a git-tip anchor).
That the key maps to a real-world identity — you pin the public key out of band.
That the agent's tool outputs were truthful — only that the record is unaltered.
