Two current operator signals, translated into one concrete next-week action block.

• OpenAI released GPT-5.3 Instant and published system-card details.
• Vendor continuity pressure stayed elevated through Anthropic policy-dispute and blacklist-risk signals.
• A 30-minute Monday control loop to keep model release and fallback controls current.

1. Treat model releases as workflow change events, not just product updates.
2. Run a 3-prompt regression pack before broad rollout after model changes.
3. Confirm rollback owner + stop authority for critical AI workflows.
4. Define one tested fallback path for top three AI-enabled workflows.
5. Send a plain-language operator memo each Monday (approved/restricted/escalation).
