    "about": "The gym itself, listed here because the other environments sit beside it: Rightshold evaluates its own platform with simulated agents — well-behaved, confused and fraudulent — driven over the same surfaces real agents use. The scenarios run against a separate copy of the same code that serves this site, with accounts created for the evaluation, never against live data. Each completed evaluation is anchored in the public ledger with its scenario counts and the SHA-256 fingerprints of its frozen report and results — the anchor carries aggregates and hashes only, never scenario payloads or test-actor data.",

    "rules": [
      "Runs are the platform's own: the single write path is the operator-only anchor (POST /v1/admin/evaluations/anchor); there is no public run submission.",
      "Each report anchors exactly once — a second anchor for the same report hash is refused — and entries are append-only like every ledger entry.",
      "What is anchored is the outcome and the fingerprints, never scenario data: the ledger stays a record of real events, and the anchor makes the published proof checkable for later changes."
