GenerativeUniverseClosureOutpost
What this is
A GenerativeUniverseClosureOutpost is a RelationalEntity that has satisfied U_G conditions 1–4.
A GenerativeUniverseClosureOutpost MUST have id and description — the identifying predicates of any RelationalEntity.
It has canonical identity (conditions 1–2) and its named operations are first-class objects in the relational graph (condition 4): other entities can invoke them, reference them in frontmatter, and compose with them. Condition 3 (limits and colimits) is an open question for the growth sequence — see relational-entity.
What a GenerativeUniverseClosureOutpost does NOT have: governing axioms constraining its operations (condition 5 not satisfied), structural generative procedures defined on it (condition 6 not satisfied), and it is not live (condition 7 not satisfied).
The operational surface
A GenerativeUniverseClosureOutpost presents a surface. Agents can enter and do work using its named operations. But those operations are ungoverned — there is no principle that rules which operations are valid, no shape that classifies what belongs, no document stating what must never be compromised.
A GenerativeUniverseClosureOutpost MUST have at least one named operation that is itself a RelationalEntity in the graph.
This is the Σ-algebra stage: carrier plus named operations, no axioms. The operations exist as first-class objects. They cannot yet be held to a standard, because no standard has been stated.
Relation to the depth filtration
A GenerativeUniverseClosureOutpost sits at depth 4 in the depth filtration — past bare identity, into the operational graph, but short of the self-governing stages. It is a valid entity at this depth. Growing past it requires stating the axioms that govern its operations, producing a GenerativeUniverseClosureBlueprint.
