Give a page of them real teeth
1Make a written copy
Opens the agreement desk prefilled with these exact words. Nothing is sent anywhere — the page just hands the printer the words to write down.
Open it prefilled2Sign, seal, keep a copy
At the desk you seal the exact words with a fingerprint, print a clean sheet, sign it in ink in front of the building, and every door keeps a bundle. If two copies ever disagree, a seal was broken.
The honest boundary
The seal proves the words match — it cannot prove who signed them or that anyone did. The paper, the ink, and the witnesses do that. A seal cannot be broken quietly, which is exactly why a written copy in every hand beats one copy in a drawer.
A licensed notary who signs and stamps the sheet is making the witnessing official — a registry of them is coming on incorporated.ink, and the in-browser ceremony with it, once identity lands (#42). A draft stays a draft until a building seals it. That line doesn't move.
