Open your AI Operating Charter and the Day 1 boundary. AI/GPT is not required just to use this day map; the linked sessions use supplied records and guided simulation.

Show the day’s evidence

Open your AI Operating Charter. Ask a partner to use it without your explanation. Mark one unclear field, revise it and preserve the supporting record. Do not substitute confidence for proof.

An incident record and value question ready for Session 7. Use S8 to explain the incident to a manager in two minutes. Partner asks what is known, what the customer still needs and what the repair cost. Select a value measure and align its reporting period.
