Answer

Does it cover what happens after a deal is signed?

Partly, and each step names where it stops. A signature envelope produces verified events and a hashed signed artifact, and exactly one immutable Order is built from the approved quote version (C-09); that Order activates into a Commercial Contract, an immutable contract version, a Subscription and explicitly pending delivery and service obligations (C-10); those obligations hand over into a Delivery Project with work packages, milestones and an optional partner, atomically and idempotently (C-11), which records append-only time and expense evidence costed server-side by a versioned fingerprinted policy (C-12). Nothing bills, renews, amends or cancels — there is no scheduler, so auto-renew and notice periods are recorded and never fire — and nothing schedules, staffs, computes percent complete or bills. Deliverables and recorded customer acceptance do exist as of M14b2 — acceptance there is evidence a user actor recorded, never an authenticated customer, a legal signature or authorization to bill. The contribution estimate is deliberately not a margin: no revenue recognition, no cost of goods sold, no ARR/MRR/TCV, no annualization, no FX, and a project carrying a recurring obligation returns no estimate at all and says why.
