The formal companion to How the Cooperative Could Grow. Where that page introduces the model in plain language, this one states it precisely: what a vessel is, which promises are invariant, what conditions govern each transition, and what the record must carry for the whole to remain one system. It is a theoretical specification, drafted for review. It binds no one and decides nothing.
The specification uses a small vocabulary. Each term is defined here in ordinary words and used consistently below. Terms the Lexicon already defines are used in its sense and not redefined.
The model recognizes three vessel states. Only V1 exists. The states are not phases the cooperative passes through and leaves behind; a later vessel joins the earlier ones, it does not replace them.
| State | Form | Membership | Scope | Status |
|---|---|---|---|---|
| V1 | Colorado limited cooperative association, public benefit entity, taxed as a partnership (the entity pays no income tax; each member accounts for their share) | Individual people | The ground: the space, its lease and insurance, the commons, the member record, voluntary contribution | Filed; the entity exists and is not yet operating |
| V2 | A second Colorado cooperative, taxed as a cooperative corporation | An open design question, resolved at formation. Organizations (the ventures, and the V1 partnership among them) may be one member class among several; the class structure is a T1 readiness condition, not a premise of the model | The growth: ventures, employed staff, shared venture assets, participating capital on defined terms | Anticipated; deferred by design during formation |
| V3 | A purpose trust: an entity organized around a purpose rather than around owners; jurisdiction an open question for counsel | No owners; a trustee bound to the stated purpose | The keeping: standing to enforce the invariants against every sibling, stewardship of the standard agreements and record grammar, translation across borders | Open and exploratory; an inference from the formation record, stated as such |
The division of labor is the model's central claim: V1 and V2 do things; V3 keeps things true. Working precedents for the V3 shape exist in what is now called steward-ownership, including Patagonia's 2022 transfer of its voting stock to a purpose trust and Organically Grown Company's 2018 move to a perpetual purpose trust in Oregon. Precedent shows the shape is real; it does not decide whether it is right here.
Every vessel, present and future, must satisfy all six. A transition that would leave any invariant unsatisfied in any vessel must not proceed.
The model defines two transitions. Each waits on readiness conditions, never on the calendar: the horizon estimates in the companion page (roughly one to three years for T1, three or more for T2) are orientation, not commitments, and appear nowhere in this section on purpose. If this model were adopted, T1 and T2 would stand in the Almanac as named conditions, the way Q1 and Q3 do today: work that waits on soil.
The connective tissue between vessels is not goodwill; it is the record. These requirements make INV-6 operational.
A vessel conforms to this model when all six invariants are satisfied in its founding instrument and its practice, and when any transition it has undergone met its readiness conditions and left the required events in the record. Because every figure is a tally and every event is kept, conformance is checkable by reading, not by trusting: a member, or eventually the V3 trust, can recompute any claim from the events beneath it and walk any finding back to its anchor.
The specification itself changes by the same discipline it describes. Revisions are versioned (MM-0.3 and onward), proposed in writing, and adopted, if ever, by member vote. The invariants are the exception: this model offers no procedure for weakening them, and a future document that did so would be a different model, not a revision of this one. That asymmetry is deliberate. Everything else here is scaffolding that should bend to what the members learn; the six promises are what the scaffolding is for.
