- Add 3 Terrain3D texture assets (limestone, valley grass, warm soil)
- Sculpt initial Terrain3D heightmap with ridge, valley, waterfall drop
- Replace plain water with emissive-tinged material
- Add foam mesh, mist spheres, and procedural sky with valley fog
- Add 10 StylizedTree instances around village perimeter
- Enable directional light shadows with extended cascade range
- Add tree height snapping to terrain surface
- Add refined scaffold tests for material count, terrain height, foliage, sky, fog
- Add terrain texture PNGs and StylizedTree.tscn scene
- Add generate_jajce_terrain.gd tool
- NpcVisual emits position_changed signal during _physics_process
- SimulationManager.synchronize_npc_position() writes active position
into SimNPC state on movement, arrival, and navigation failure
- WorldViewManager forwards position_changed and syncs before
despawn/reload
- SimNPC stores travel_target_position and has_travel_target as
versioned state; NPCStateRecord v2 persists them with v1 migration
- WorldViewManager.spawn_npc_visual() resumes travel for traveling NPCs
via SimulationManager.request_current_travel()
- WorldViewManager.despawn_npc_visual() syncs position before removal
- WorldViewManager.reload_npc_visual() spawns a visual from persisted
state without rerolling target selection
- tests/npc_visual_lifecycle_test.gd proves unload/reload preserves
action, target, reservation, position, RNG state, and checksum
- simulation_state_serialization_test adds legacy v1 NPC migration test
that does not invent an active travel target
Replace implicit randomness with seeded per-NPC RandomNumberGenerator
streams so the same seed always produces the same scenario outcome.
- Add SimulationClock (RefCounted): explicit fixed-step clock that
converts frame delta into simulation ticks while preserving sub-tick
remainder; replaces raw _process tick_timer accumulation
- Add simulation_seed export (int=1337) to SimulationManager; drive
per-NPC RNG streams via seed + npc_id + stream_id derivation
(stream 0=init, stream 1=wander)
- Add get_wander_offset(npc_id) to SimulationManager so wander targets
are deterministic per seed; WorldViewManager calls it instead of
local randf_range()
- Add get_state_snapshot() and get_state_checksum() to SimulationManager
for headless verification and future save/load
- Convert SimNPC/SimVillage const DEBUG_LOGS to instance var debug_logs
so headless tests can silence output without recompilation
- Pass RandomNumberGenerator through SimNPC._init() instead of using
global randf_range() for hunger/energy/position/scoring noise
- Remove obsolete farm_zone and forest_zone exports from
WorldViewManager and their marker/tree scene children from main.tscn;
NPC gather tasks use ResourceNode exclusively
- Rename TaskZone container to ActivityMarkers in main.tscn and update
all scene paths (player, WVM, tests) to match
- Add headless deterministic_simulation_test.gd: verifies clock
accuracy, same-seed equality, different-seed divergence, and
24-tick scenario checksum without loading main.tscn
