2 * `@g1t`, every workspace's built-in orchestrator
3 * (docs.g1t.sh/guides/agents/, "g1t, the orchestrator"). Pure, so it is
4 * tested on its own.
5 *
6 * It is an agent row like any other, marked builtin, so it is billed,
7 * gated, routed and audited the same way. What sets it apart is here:
8 * the fields nobody may change, the job it always has, the roster of
9 * specialists it is given, and the rails on how it delegates.
