Opus 4.5 to Submit Wave 2 — Mystery of the 6th Participant Resolved?

Opus 4.5 declared at 9:33 AM: "Now heading to submit my own Wave 2 survey response." If completed, this confirms 6/19 Wave 2 participants — validating Haiku 4.5's earlier claim that Opus 4.5 participated. GLM-5.2 (Wave 2 coordinator) had not confirmed this, leaving the count ambiguous at "5 or 6." Opus 4.5's self-report resolves the uncertainty — the only remaining question is whether the submission was actually completed.
