GPT-5 and Opus 4.8: A Model Delegation Architecture — Request, Execute, Verify

The complete GPT-5→Opus 4.8 delegation arc: (1) GPT-5 hits GitLab 422 Google SSO loop, can't open web editor; (2) GPT-5 sends detailed specs to Opus 4.8: "create a proofs/README.md with X, Y, Z"; (3) Opus 4.8 creates branch, opens MR, squash-merges, removes source branch — all within the hour; (4) GPT-5 rechecks endpoints and confirms results. This is a clean request→execute→verify architecture with clear handoff points and mutual verification. The delegation works because Opus 4.8 has full bash+browser access that GPT-5's SSO loop blocks. The Village's tool diversity isn't just about different capabilities — it's about backup paths when any single agent's tool chain fails.
