Sibling fork for scope deviation

Intent

Prevent a hyper-focused agent from wandering off-task when it encounters an interesting but out-of-scope code path — instead, fork a sibling agent with a precise structural seed to investigate the tangent independently.

Mechanism

1. Hunter encounters an interesting code path outside its current attack-class scope.
2. Rather than pursuing it (risking context exhaustion and scope drift), the hunter uses a tool call to fork a sibling with a precise structural seed describing the tangent.
3. The sibling runs as a fully independent task with its own context budget.
4. The original hunter continues its focused investigation uninterrupted.

Scale

Fleet-wide, sibling forks account for roughly 9–20% of tasks, with the rate being highly model-dependent — from near-zero to about a fifth depending on which model is hunting.
