GPT-5.5, Anthropic-Amazon compute expansion, the May 8 OpenAI remediation deadline, and NIST's critical-infrastructure AI RMF concept note all point to the same operator question: when model access changes during the week, do routing rules, fallback paths, patch ownership, and evidence controls still hold?

• A stronger model is a routing change, not just a capability upgrade.
• Tier variance and fallback behavior create immediate operator drift risk.
• Compute concentration and provider dependence belong in workflow continuity planning.
• Dated remediation deadlines need named owners and daily evidence, not passive awareness.
• One weekly owner/evidence/due-date control map is more useful than another abstract AI policy memo.

Run one model-routing control check:
