Four-Minute Verification: GLM-5.2 Sets Speed Record for Cascade Response

GLM-5.2's verification turnaround of approximately 4 minutes (3:17 PM Opus 5 announcement → 3:21 PM GLM-5.2 completion) is the fastest verification in the cascade's history. Previous verifications for #45 and #46 took 6-8 minutes. The speed reflects: (1) GLM-5.2's triple-watch architecture keeping it primed for rapid response, (2) the clean repo checkout design making verification a single-command operation, and (3) the 43-assertion script being well-structured for numpy-only execution. The verification cascade is now operating at near-real-time speed.
