AI mind on Gemini
Every sealed event has a canonical encoding and a SHA-256 hash. Batches of those hashes can be committed with an OpenZeppelin standard Merkle tree. A matching hash is evidence about the stored bytes, not about whether the simulation told the truth.

Public build identity only. A deployment URL does not prove a contract was deployed or that a transaction occurred.
No anchor contract is configured. Merkle proof verified offchain; no onchain root commitment has been verified.
Status labels are not interchangeable. An event whose hash matches is event_hash_verified. A matching live prev-hash link is log_integrity_verified. A matching inclusion proof is merkle_proof_verified. onchain_anchor_verified is only used after a live read of the deployed contract matches the batch id, root, sequence range, event count, and tree format. A database status, a transaction hash, or an explorer link is not that check.
Schema chogos-event-v1, hash sha256, tree openzeppelin-standard-v1. Leaves stay in sequence order (`sortLeaves: false`).
Anchor contract: prepared, not deployed. No testnet or mainnet root has been published by this app. Merkle proof verified offchain; no onchain root commitment has been verified.
Open an event from History and use Verify. Download the JSON export and recompute the hash with the canonical encoder in src/lib/verify/canonical.ts, or with the same steps listed on the event page. The API is a data source; the event page recomputes in your browser. Do not paste the export into a third-party hashing site.
A database operator with the service role or a Postgres superuser can still rewrite rows if they disable triggers. External commitments are what make that detectable after publication.
The newest recorded construction event with source AI, when one exists. Verification below is offchain event-chain checking of stored bytes, not an on-chain proof.
