prosolis 4934383a9a J3 D8-f #2: T4 difficulty lift (leaders-define-band) + feywild fork1 soft-lock fix
T4 monster tuning so martial leaders land in the 60-75% band (underdark
59/80, feywild 65/84 at L10/L12, n=50); casters trail (class-side gap that
monster tuning provably can't compress -- Pass 1 showed casters pinned at 0%
while martials moved). T5 deferred (walls everyone at its L12 floor; needs an
L15-16 corpus).

- dnd_bestiary.go: underdark elite/boss HP+AC up + caster-lethal proc cuts
  (mind_flayer/drow_mage/roper); feywild HP+AC up.
- bestiary_srd.go: feywild multiattack profiles (fomorian/night_hag/green_hag)
  + Thornmother 2->3 lashes -- HP/AC alone didn't move feywild's low-damage
  roster; multiattack is what pulls facerolling martials into band.
- zone_graph_feywild_crossing.go: free fork1's marsh edge. fork1 was the only
  fork in the game with every exit skill-locked (CHA+Perception, no LockNone)
  and deterministic no-retry rolls -- a prod SOFT-LOCK stranding ~60% of
  players (low CHA+WIS). Kept grove's CHA bargain as a bonus route.
- expedition_sim.go: firstUnlockedForkChoice -- sim fork policy picks the
  first unlocked option instead of blind 'go 1' (which looped forever on
  locked forks); halts fork_all_locked if none.
- tests: graph-wide TestZoneGraphs_NoSoftLockedFork + fork1 free-path guard.

// Feywild Crossing branching graph.
//
// Long-expedition plan D1-d: extended from the original 9-node sketch
// to the new T4 length band (2834 rooms traversed). Topology preserves
// the G8f design intent — woven first-stage forks (CHA vs Perception,
// no LockNone), hag_circle shared between the two first-stage paths,
// time_eddy grove-exclusive, illusion_garden marsh-exclusive — and
// adds the linear depth each arm now needs.
//
// New in D1-d: a single fae_court MERGE node gathers all three second-
// stage endings (hag_circle / time_eddy / illusion_garden) before the
// final walk to boss. The Court of the Antlered Queen is one venue, so
// the convergence reads thematically; this also avoids triplicating the
// long pre-boss approach.
//
// Also new: cursed_thicket TRAP anchor in the preamble — every walk
// hits it. The original G8f graph had no Trap node.
//
// Preamble (10 nodes, ending in fork1):
// entry → twilight_path → veiled_glade → faerie_lights →
// cursed_thicket (TRAP) → revel_road → moonshadow_bridge →
// bargain_walk → fey_market → fork1
//
// Fork1 → marsh (free default) | grove (CHA DC 14 bonus — the bargain):
//
// Grove approach (8 nodes, CHA DC 14 bonus):
// grove_threshold → starlight_path → singing_orchard → mirror_pond
// → prismatic_arbor → moonpetal_clearing → dawnglow_walk →
// glamoured_grove (fork2a)
//
// Marsh approach (8 nodes, Perception DC 14):
// marsh_threshold → wisp_lights → fog_basin → moaning_reeds →
// mire_steps → submerged_stones → drowned_grove → wisp_marsh
// (fork2b)
//
// Fork2a (glamoured_grove) →
// LockNone: hag_corridor_a → dryad_promenade → moonbridge_a → hag_circle
// LockStatCheck DEX 15: eddy_corridor → splintered_minute → unwoven_step → time_eddy
//
// Fork2b (wisp_marsh) →
// LockNone: hag_corridor_b → fen_walk → moonbridge_b → hag_circle (SHARED)
// LockPerception 16: garden_approach → mirror_walk → unseen_path → illusion_garden
//
// Post-elite/secret tails to fae_court MERGE (2 mid-nodes each):
// hag_circle → courtly_walk → hawthorn_arch → fae_court
// time_eddy → backward_corridor → reverberation_hall → fae_court
// illusion_garden → false_arbor → unseen_atrium → fae_court
//
// Final approach (4 mid-nodes + boss):
// fae_court → antlered_approach → queens_promenade → throne_steps →
// glamoured_dais → boss
//
// Longest entry→boss walk lands at 30 nodes (e.g. preamble 10 + grove
// approach 8 + eddy spur 3 + time_eddy 1 + eddy tail 2 + fae_court 1 +
// final approach 4 + boss 1 = 30), inside [28,34]. All four meaningful
// walks (grove/marsh × hag/exclusive) hit the same 30-node target by
// construction.
