Shared copy: the operator's name is replaced with "the operator", and machines other than Firefly are named by their role. Nothing else is changed.

What is built now

Nothing as roles. The N sessions in 16 are identical workers; the driver is the only orchestrator.

What is missing

Everything; the spec itself said only the validator role is adopted unconditionally.

Reviewer Claude, 2026-10-04

Reviewer's read: Deliberately deferred

The spec was self-limiting in the right way: every role beyond the judge had to earn its keep one at a time. The deterministic validator (18) already fills the judge role. No role has been proposed with a measurement attached.

How it is measured deferred

One role at a time, each as an arm against h1-v41.

Adoption rules shared by every arm: How the tests work.
