Subagent

A signed, scope-restricted agent spawned by the kernel for a separable concern.

Definition

When a problem is genuinely distinct — solver debugging, resource research, UI verification, report review — the kernel spawns a signed subagent with a constrained tool budget. Subagents have their own rollout segment; they return typed findings to the parent without polluting its context.
