What this covers

This is a placeholder so the layout can be verified end to end. The real article follows the problem-to-solution model: the pain, the mechanics, the numbered steps with tools, then the check that proves it worked.

1

Establish what you actually have

What you do: pull the record, then compare it against the requirement before deciding anything. Most of the cost in this process comes from acting on a partial picture.

Frequently asked questions

Is this the final copy?

No. This is scaffolding so the design can be reviewed with realistic structure in place.

Where does the real text come from?

The reworked TOP-20 briefs, reviewed with Gemini before publication.
