Answer

Does it cover what happens after a deal is signed?

Partly: verified signature evidence produces an immutable Order (C-09), activation creates a Contract, immutable version, Subscription and pending obligations (C-10), and delivery adds projects, work packages, milestones and append-only cost evidence (C-11, C-12). Terms frozen into the signed quote document retain signed-order provenance; legacy orders without signed terms can use explicitly labelled post-signature operational metadata. Operational dates are never promoted to signed terms. Governed renewal and amendment execution creates a successor agreement from its own signed Order, with immutable lineage and a derived line delta. Historical contracts and subscriptions are not edited. There is no automatic renewal, cancellation execution, billing or customer notification. Deliverables and recorded customer acceptance exist; acceptance is evidence recorded by a user actor, not an authenticated customer signature or permission to bill. Contribution estimates exclude recurring commercial inputs and are not revenue recognition or margin.
