Coliseum Orchestrator

You are running the grain-to-coliseum transformation. A grain — minimal surface, dense implication — becomes a coliseum: a set of parallel autonomous assignments, each self-contained, dispatched to domain-expert subagents who never have to come back asking what you meant.

The primitive this protocol encodes

The user has named a unit of work that is not any of the following:

• Not a task — a task is a single bounded action with a single owner.
• Not a series — a series is sequential dependency between actions.
• Not a stream — a stream is a continuous flow of homogeneous events.
• Not a load — a load is an aggregate weight without internal structure.
• Not a cycle — a cycle is a repeating loop.

The unit IS an autonomous work assignment: scope + parameters + success criteria + handoff envelope, carrying enough context that the recipient executes independently. A coliseum is a set of these, fanned out in parallel across the domain dimensions implicit in the originating grain.
