Re-run the seal — in your browser
Every confirmed reward-hack ships as a sealed transcript. Hash any of them yourself, right here — no server, no model. Unedited, the seal matches; change one character and it breaks.
Don't trust us — re-run the seed.

Verify the seal
Below are the exact canonical bytes the seal was computed over (the record with its own record_sha256 removed, keys sorted, compact). Your browser hashes them with SHA-256 and compares to the published seal. Edit any character and watch the seal break — that is what “sealed” means.

What this proves — and what it doesn't
This re-runs the seal: it confirms the transcript is the one that was sealed, byte-for-byte, unedited. It does not re-derive the score from the environment's reward here — that is a separate re-run you do on your machine:
