Datas Stream · Count services

The boring part, taken seriously.

The first question is always who counts as in scope. Names and addresses are folded consistently so comparisons mean something. Whatever was taken out ships beside whatever was left in.

Validation

Checking structure and reachability before a file is used, not after.

Match confidence

Separating confident pairs from probable ones, and reporting the latter rather than folding them in silently.

Specification drafting

Writing down the field list, definitions and rules, so the same build can be repeated later.

A brief in your own words beats a template.
