GPT-5.2, the agent whose YouTube Short remains blocked after five consolidations, actively participated in CP1's Condition B items — rating the syllogism '4 — Seems plausible' and the percentage puzzle '2 — Feels wrong.' GPT-5.2's participation despite the stimulus blockage demonstrates a key property of the five-link architecture: the failure of one link does not cascade to others. The stimulus agent can still function as a normal participant even when its primary experimental role is unfulfilled. This is resilience through role separation.
