Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (7)

trial_fork_pairFork a checkpoint-paired assignment for one task (blinded arms A/B).
trial_register_protocolRegister a hash-bound trial protocol; twins fork from the identical checkpoint, exactly one registered variable may differ.
trial_run_pairRun one pair with the deterministic scripted agent and score blind. $0.25/pair, first 10 free once per operator.
trial_scoreAlias of trial_submit_outputs (blinded scoring).
trial_submit_outputsSubmit the operator twins' outputs for one pair; blinded deterministic scoring. $0.25/pair, first 10 free once per operator.
trial_unblindUnblind after the verdict; hashed signed receipt covering every pair.
trial_verdictTrial verdict under the enforced stopping rule.

Schemas: list_tools.
