This phase runs several things at once rather than in strict sequence: standing up the shared backbone no single clinic can build alone, seeding the next local cooperatives that will eventually connect to it, and — where the legal and financial structure calls for it — establishing an affiliated, legally distinct nonprofit arm alongside the cooperative to carry charitable and community-facing work the cooperative structure itself isn't built to hold.
A generic composition, not a specific design — the shape reflects proven patterns from federated networks already operating elsewhere, adapted to this framework's own structure.
What this actually requires, component by component:
Shared technology & data — one infrastructure for records, scheduling, and outcome tracking, so Phase Five's measurement discipline can actually scale across sites instead of living in one clinic's private system.
Mutual insurance & risk pool — a member-owned vehicle for shared risk, the same structural instinct that lets small, independent organizations self-insure collectively rather than each facing catastrophic exposure alone. This is where Phase Three's fee strategy — the major-medical tier specifically — eventually connects to something the federation itself owns, rather than an outside insurer.
Quality & credentialing — shared peer review and quality standards, so a patient's trust in the model doesn't depend on which site they happen to walk into.
Education & training — the mechanism that lets Phase Five's clinical discipline actually transfer to new sites and new practitioners, rather than living only in the founding team's judgment.
Advocacy & collective voice — representation that no single small, independent clinic could afford or command alone, but that a federation of them can.
A community foundation — where warranted, a legally distinct 501(c)(3) affiliate, connected to the backbone but structurally separate, built to hold the charitable and grant-eligible work a distinct nonprofit vehicle is suited for.
Target Endpoint: a backbone doing real work for more than one site, and at least the beginning of the next local cooperative it will eventually support.
