Prepare.
The agreement enters as a document. SignIT proposes recipient fields and geometry without sending anything.
Private alpha / controlled access
From agreementto evidence.
SignIT prepares, routes, signs, and verifies one controlled agreement record — with permission-controlled AI doing the work and people authorizing the moments that matter.

The problem / disconnected state
The PDF is not the hard part.
The handoffs around it are. Email, approval, preparation, identity, signing, and proof drift across systems until no one owns the complete record.
How SignIT works / MSA-024
One agreement. Five controlled states.
Follow a synthetic Northwind Labs MSA from preparation to an evidence-backed completion record.
Prepare / proposed, not sent
Turn a document into an intentional signing surface.
SignIT can detect and propose fields. A person confirms the recipient, field type, and canonical placement before the envelope can move forward.

Sign / explicit consent
A focused ceremony for the intended signer.
Private-alpha signing uses a capability-scoped link. The recipient sees the agreement, confirms consent, fills assigned fields, and explicitly finishes.

Evidence / the infrastructure
Signing is visible. Proof is structural.
Completion is more than ink on a page. SignIT binds the document, signer, field geometry, consent, timestamps, certificate, and ledger into a record that can be checked.

AI + MCP / permission controlled
Callable by agents. Governed by people.
A compatible MCP client can read, draft, prepare, and propose inside its organization scope. Consequential operations remain proposals until the server receives human authorization.

Security / architecture over adjectives
Trust is enforced at the boundary.
SignIT is an early private alpha, not a certified or independently audited service. These are implemented architectural controls, not compliance claims.
