Phase 9+10: Status/Doctor/Medical bed + Wolves/WolfSpawner

The 'drama pair' shipped together via 3-agent fan-out. Phase 9 — Status effects + Medicine: - Status data class (PERSISTENT/EVENT, severity stacks max=3) + StatusCatalog (Bleeding ticks HP loss; Downed = incapacitated) - Pawn HP (100 max, 30 downed threshold, 50 revive threshold), take_damage, heal, add_status/remove_status_by_id, is_downed/is_incapacitated, downed visual (body rotated 90° + desaturated) - DoctorProvider (priority 9, highest) — scans World.pawns for nearest downed pawn, finds medical bed (or any bed fallback), emits 4-toil job: walk_to_patient → rescue → walk_to_bed → treat - Bed.is_medical with red-cross marker draw on pillow; round-trips save - KIND_RESCUE + KIND_TREAT toils + JobRunner _tick_rescue/_tick_treat (snap-to-bed on first treat tick, +0.5 hp/tick, bleed cure at 100-tick intervals; done at HP≥50 + no bleeding, 600-tick timeout) - EventBus: pawn_took_damage, pawn_status_added, pawn_status_removed Phase 10 — Combat + Wolves (wolf-first slice): - Wolf entity (Node2D, 4-state APPROACH/ENGAGE/FLEE/DEAD, procedural canine sprite with red glowing eyes, 40 HP) - Two-roll combat: 70% hit + 50% chance to apply Bleeding(1) on hit - WolfSpawner — triggers at Clock.darkness_factor()≥0.8 with 1-in-game-day cooldown, packs of 1–2 at random map-edge cluster - World.wolves registry + register_wolf/unregister_wolf Integration: world.tscn load_steps 15→17 with DoctorProvider + WolfSpawner nodes. world.gd registers doctor at top of provider list (priority 9 > sleep 8 > eat 7 > construction 6 > chop≈plant 5 > mine≈craft 4 > haul 3 > rest 0). Middle bed at (47,24) marked is_medical=true. MCP runtime verified: Bram took 75 dmg + Bleeding(2) → Downed (hp 25) → Edda + Cora both volunteered doctor job → walked to patient → carried to medical bed → treated → Bram healed to 94.2 hp, statuses cleared, back to work. Wolf raid at day 3 22:00 fired; 4 wolves alive across raid cycles by day 4 01:51. Screenshots confirm red-cross medical bed and wolf silhouettes at night. Phase 10 deliberately partial: wolf-side combat ships, pawn-side weapons/armor/cover/friendly-fire deferred — full chain (wolf→bites→pawn→bleeds→doctor) awaits player weapons. Bleed-out timer at demo value (1200) vs design value (432000 = 6 in-game hours) — documented in status_catalog.gd for first time-balance pass. Delegation: Agent A (status + pawn HP), Agent B (doctor + treatment), Agent C (wolf + spawner) — all Sonnet gdscript-refactor; integration on Opus.

+class_name DoctorProvider extends WorkProvider
+## WorkProvider for the Doctor work category. Slots into the 5-layer pawn AI
+## (Decision → WorkProvider → Job + JobRunner) at priority 9 — above sleep (8)
+## so able-bodied doctors volunteer for rescue before their own rest.
+## Phase 17 will expose this via the work-priority matrix so the player can
+## set individual pawns to Doctor=Off.
+##
+## Rescue model (Phase 9):
+##   A doctor pawn picks the nearest downed pawn that has no doctor already
+##   assigned to them.  The job is a 4-toil sequence:
+##     1. walk_to(patient.tile)    — doctor walks to the downed pawn
+##     2. rescue(patient_path)     — single-tick marker (doctor "arrived")
+##     3. walk_to(medical_bed.tile)— doctor walks to the nearest medical bed
+##     4. treat(patient_path)      — multi-tick: snap patient to bed, heal until
+##                                   HP ≥ 50 AND not bleeding, or 600-tick timeout
+##
+## Phase 9 simplification: the patient is teleported to the bed on the first
+## tick of the treat toil (no carry visual). Phase 17 may add a proper carry
+## animation and render the patient following the doctor during the walk.
+##
+## Bed preference: medical beds (is_medical=true) over regular beds.
+## Fallback: any available bed if no medical bed exists.
+## Hard fail: if no bed is available at all, the job is not issued and
+## Audit.log records the skip so the developer can see the bottleneck.
+##
+## Pawn and Bed are intentionally duck-typed to avoid the class_name
+## registration-order trap documented in Phase 2/3.
