Half the work is deciding what counts.
If a requirement can be specified it can be sized, and sizing happens first. The file is deduplicated against anything previously supplied to you. Every claim the file makes about itself can be checked against it.

Stating how long we keep what was built, and what happens to it afterwards.
Domain attribution
Establishing which web presence belongs to an organisation rather than to its host or its agency.
Supply assessment
Saying plainly where the available data stops, including when it stops short of the brief.
