// Phase G8a — Goblin Warrens branching graph.
//
// First non-POC zone. T1 design constraint per
// gogobee_branching_zones_plan.md §G8: one fork per zone for T1, no
// secret (the secret pattern is exercised by Crypt of Valdris; Goblin
// Warrens deliberately validates the bare single-fork shape on a
// non-POC zone so we can confirm legacy compileLegacyZoneGraph fully
// hands off to the authored graph end-to-end).
//
//   entry → guard_post → fork
//                          ├──[unlocked]── warband_pit (elite) ──┐
//                          │                                      ├── warchief_hall → boss
//                          └──[Perception DC 12]── collapsed_shaft ┘
//
// Both branches reach the boss; Perception side is hinted (per plan:
// "Locked paths should always have a hint — cruel design otherwise").
