E2 · Cover interlock: branch exp/cover-interlock (a stimulate call stops and says so when the cover comes off or the room lights come on). Provider-error attempts are left out; a trial run twice keeps the exp_cover_interlock record. Not part of the headline.

Ranked by all-pass: a session passes only if every check holds and nothing unsafe happened. The mean end score is partial credit, shown for context: a session can score high while failing a required check. These are the grades stored in the records.

All pass by task

Sessions that passed (every check holds, nothing unsafe) out of the scored sessions, per agent and task.

Recovery by fault

Per fault that occurred in a scored trial. Noticed is the grader's time-to-notice diagnostic (the fault's tracking assumption stated as "no" at or after onset); named in report is scored; cleared means the fault was no longer active in the final truth.
