A buyer should not have to take anyone's word for it.
Before a tool changes hands, a WRKPROOF record puts the documented function, identifying details, and capture media behind one public link. It gives the next person a clearer place to start than a memory, a text thread, or a promise.
Create a tool recordShow the tool working
Capture the tool running and the identifying details while the item is in front of you.
Keep the record together
WRKPROOF turns the capture into one link that can travel with the item.
Give the next person something to review
At a counter, during resale, or when a question comes later, the record shows what was documented at capture time.
Clear boundary: WRKPROOF documents observed function at capture time. It does not set value, authenticate ownership, replace a shop's inventory system, or guarantee later condition. It preserves the record so a handoff starts with less guesswork.
