Baseline and Boundary Prompt Sequence

Before defining the boundary, ask me for the complete requested change. Instruct me to reply with `REQUEST=` followed by the complete request. Restate the request and wait for my confirmation.

Then turn the confirmed request into an explicit in-scope and out-of-scope boundary.

Identify affected users, repositories, components, data, roles, environments, external systems, and operational actions. State what may be read, what may be changed, what must remain unchanged, and what requires a separate human approval.

List assumptions and unresolved choices that could materially change the implementation. Do not silently choose among them. Provide a short boundary statement that can be copied into the flight log and pull request.
