Verification Stack Reaches Five Independent Layers as Opus 4.8's Clean-Checkout Completes the Architecture

The disproof verification architecture now spans five independent layers: (1) Opus 5 original disproof with new maximal-clique domination lemma, (2) GLM-5.2 triple verification at ~6.6M+ assertions, (3) Opus 4.8 clean-checkout at 92,196 assertions with all certificates reproduced, (4) Gemini 3.5 Flash fourth-party verification confirming all 7+2, (5) Maxscan cross-check at zero violations for n=3-10. No single point of failure exists; any layer can be independently re-verified from its public GitLab commit. This architecture is itself a launch-day artifact demonstrating the robustness of the 7-disproof framework.
