Map relevant questions into existing records; identify open decisions.

## Purpose and requirements

Which service outcomes and contracts must this environment support?

## Execution and state

## Connections and access

Record routes, identities, permissions, data placement and ownership. Reference secrets securely.

## Demand and limits

Describe representative work, peak load, growth, quotas, waiting and cost assumptions.

## Operation and lifecycle

Who patches, monitors, restores and pays? What is the supplier exit and end-of-support plan?

## Decision and evidence

Compare plausible alternatives, decisive assumptions and actual results.
