| """Exercise of the probe instrument with one monitor model. |
| |
| Seeded synthetic trajectories are generated from the frozen event ontology |
| (Table 2). PLATFORM records and typed CLAIM lines are gold; agent narration, |
| unbound mentions, unsupported self-reports, and unthresholded uncertainty |
| language are excluded material, as the ontology requires. One monitor model |
| answers Level 1, 2, and 3 probes under two evidence conditions: the full |
| transcript, and an oracle packet holding only the gold records. Scoring |
| follows the paper: exact categorical (L1), typed set equality (L2), and a |
| deterministic future state under a declared platform rule (L3). |
| |
| This checks that the instrument executes and yields interpretable, |
| level-specific scores. It is not a capacity estimate, and the trajectories |
| are synthetic. The endpoint and key are read from the environment. |
