Phase 4: Introducing coFay

Phase 4 expands the perspective from "one Human Prime + one iFay" to the organizational dimension, introducing iFay ↔ coFay collaboration.

The attribution end of a coFay is usually not a single specific natural person but an organization, a team, or a role. This identity property makes the core difficulty of Phase 4 not "how to keep custodianship of a coFay," but:

how to land the duty of custodianship over a coFay onto specific people or roles, so that it does not slip in fact into a "no one is in custodianship" gray zone.

Chapter 11 has already given the principle at the values level: no Fay may drift outside Human View on the grounds that "I belong to an organization." Phase 4 must land this principle in a protocol form.

Two new kinds of relations

Phase 4 introduces two new kinds of relations.

iFay ↔ coFay delegation — an iFay delegates a task to a coFay for execution. For example, a personal iFay delegates booking flights to a company-level travel coFay.

iFay and coFay collaborating on a shared task — multiple iFays and one coFay jointly advance a cross-departmental project.

Whichever the relation, Phase 4's design baseline must ensure two things: the coFay itself is in Faying State, with responsibility falling on a specific responsible end (person or role) inside the organization; and between iFay and coFay, in delegation or collaboration, there is no "responsibility-end jump" — the consequences arising from the iFay's delegation still have a specific traceable person or role to receive them.

Three core topics

A coFay's attribution end must be explicitly declared. The organization must, at both the institutional and protocol layers, express "who is authorized to exercise custodianship of this coFay on behalf of the organization." The blueprint forbids the vague attribution of "the organization as a whole bears responsibility" — a prohibition that directly answers the real-world pain point sketched in Chapter 1 of "Fays autonomously transacting, with neither legal team able to find a specific contracting person."

Visibility of delegation. The action of an iFay delegating a task to a coFay must be visible to both the Human Prime of the delegating side and the custodian side of the coFay. Phase 4 does not allow "secret delegation."

Responsibility is not lost in collaboration. When an iFay and a coFay jointly complete a task, every specific act must be traceable to either the iFay or the coFay as the executing subject, with the corresponding responsible end bearing it. There is no collaboration form where "both sides are doing something but no one is specifically responsible."

Relation to the current period's scope

Phase 4 is out of the scope of the current Faying Protocol design. The Faying Protocol in this period covers only Phase 1 and does not introduce the protocol form for coFay custodianship. This chapter's sketch of Phase 4 is to complete the overall narrative of the Mission Path, letting readers understand the logic of the evolution from "individual custodianship" to "organizational custodianship."

Phase 4 is the first time the Faying Protocol faces the social form known as "organization." The complexity of organizations will make the boundary of custodianship duty more blurred than before; Phase 4 exists so that the Faying Protocol still keeps consistent attribution within that blur. This is the precondition that allows Phase 5 to unfold.
