## Why this rule exists

Methods differ structurally — a web checkbox, a paper form and a phone script share no visual elements — so one artifact cannot evidence several. Reviewers check them individually, and the missing ones are read as undocumented collection surfaces.

## How to fix it

Attach one artifact per declared method: a screenshot for the web form, a scan for the paper form, the script for phone consent, a capture for the QR landing page.
