Wheat + corn both produce TYPE_GRAIN; potato + strawberry both produce
TYPE_VEGETABLE. Until now they rendered identically (yellow stalks for
both grains, green-leafed root for both vegetables) since shape was
driven by item_type alone.
Added an Item.subtype field that carries the origin crop_kind through
harvest. draw_item_shape dispatches on subtype FIRST then falls back
to item_type — so storage filters (which match on item_type) still
treat wheat+corn as one Grain category and potato+strawberry as one
Vegetable category, but the visuals are now distinct.
New procedural shapes:
- wheat: 3 yellow stalks with grain-heads (same as existing grain)
- corn: yellow cob with kernel dots wrapped in green husk leaves
- potato: 2 brown overlapping lumps with sprout-eye dots
- strawberry: red heart-shape body with green calyx + yellow seeds
Crop.on_harvest_tick assigns subtype = crop_kind on spawn.
SaveSystem._spawn_item now round-trips subtype through saves.
Pawn carry indicator + Item._draw both pass subtype to draw_item_shape.
Pawns hauling items previously showed a 7×7 hue-coloured square — no
hint of what they were actually carrying. Now the carry indicator
calls Item.draw_item_shape(self, type) at 0.55× scale (~7px effective),
positioned at the pawn's upper-right (chest-height).
Refactor: _draw_item_shape (instance method) → Item.draw_item_shape
(static, takes a CanvasItem target). Item._draw() and Pawn._draw()
both call it. Also added shapes for the 5 atlas-backed types (wood /
stone / plank / iron_ore / gold) so the carry indicator works for
mining + carpenter outputs too — the on-floor visual still uses the
bundle atlas via the Sprite2D child.
NameLabel was at y=-18 — sat right on top of the sprite head when
the body grew from 12px disc to 32×32 character sprite. Bumped to
y=-38 so the name floats above the sprite (which spans y=-24..+8).
StateLabel at y=+10 unchanged — already just below sprite bottom.
Also drop temporary atlas-idx audit log (debug-only, hash
distribution confirmed Bram=004 / Cora=013 / Edda=001).
z_index=-1 was sinking the sprite below the floor TileMap (z=0), so
name labels rendered but bodies didn't. Using show_behind_parent=true
keeps the sprite at z=0 (above floor) while still drawing BEFORE the
parent's _draw() so selection ring + carry indicator overlay on top.
Pawns now render as AnimatedSprite2D children sourced from ElvGames
"Farming Characters Pack" atlases (Pack 1, characters 001-015). Each
pawn picks one of 15 peasants deterministically from name hash:
Bram=004, Cora=013, Edda=001.
Animations: idle_down/left/right/up + walk_down/left/right/up (4 fps
idle, 8 fps walk, looped) + dead (single frame, no loop). Pawn picks
animation each _process tick from (is_downed, is_walking, facing).
Facing is now a Vector2i field updated in _advance_walk; round-trips
through save/load.
Sprite mounting is deferred from _ready() to setup() / from_dict()
because the atlas pick depends on pawn_name, which isn't assigned at
_ready time. _mount_sprite() is idempotent for the save-load chain.
_atlas_for_pawn(pawn) is the single Slice-2 extension point —
swapping atlases based on equipped armor in a future sprint is a
one-function change.
_draw() stripped of body disc + downed-rotation; now overlay-only
(selection ring + carry indicator). AnimatedSprite2D child uses
z_index=-1 so the overlays stay on top.
45 PNGs copied into art/sprites/characters/ + 45 .import companions.
Three playtest-reported bugs fixed out-of-phase before Phase 18:
* Furniture build-queue gap: Torch / Bed / Crate / Workbench / CremationPyre
were missing World.register_build_site(self) in _ready, so newly-painted
designations never entered ConstructionProvider's iteration. The seeded
cabin pre-built everything via _spawn_complete_* helpers, masking the gap
until a player painted a fresh furniture designation.
* Wall-trap regression for bystanders + walk-through pawns: Wall._complete
now dislodges any pawn on the tile via new Pathfinder.find_nearest_walkable
BFS helper; Pawn._advance_walk re-checks next tile walkability before
stepping, aborts walk + cancels job + lets Decision reroute. Phase 6's
adjacent-stand fix only protected the BUILDING pawn.
* Floor / Pawn Y-sort ambiguity: Floor was anchored at tile-center
(same Y as Pawn), so Y-sort tiebreak fell to scene-tree order and
Floor (spawned later) drew over Pawn. Moved Floor origin to top-of-tile
so Floor.y < Pawn.y under Y-sort; _draw rect offsets compensate.
All three verified via MCP runtime: torch built end-to-end, all 3 pawns
working on different jobs with no idle traps, pawn renders over floor.

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.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Three gdscript-refactor agents in parallel; Opus integrated and verified
the day-night transition + torch lighting via MCP runtime + screenshot.
Clock autoload (Agent A, autoload/clock.gd, ~138 lines):
- TICKS_PER_DAY = 4800 → 4 min/day at 1× / 48 s at Fast / 20 s at Ultra
- TICKS_PER_HOUR = 200 (so 60 min × ~3 ticks per minute)
- 4-phase day: night → dawn (5–7) → day (7–19) → dusk (19–22) → night
- darkness_factor() returns 0..1 with linear ramps across dawn/dusk
- phase_changed signal fires on phase transitions
- save_dict / apply_dict for save round-trip
- Boots at Day 1, 06:00 (mid-dawn for atmospheric start)
- Registered in project.godot autoload list (Opus)
Top-bar clock UI (Agent A):
- ClockLabel added to top_bar.tscn (center-anchored at ±80 px)
- _on_clock_refresh in top_bar.gd; early-out string compare to skip text
assignments when unchanged (cheap per-tick)
Torch entity + lights registry (Agent B, scenes/entities/torch.{gd,tscn} +
workbench.gd + world.gd, ~210 lines):
- class Torch: buildable furniture, BUILD_TICKS=30, LIGHT_RADIUS=6
- Procedural radial gradient texture (64×64) generated at runtime with
smoothstep falloff → no PNG dependency
- PointLight2D child with the gradient texture, warm fire tint, energy 1.2
- is_on / get_light_tile / get_light_radius duck-typed interface; same
shape exposed by Workbench when label_text='Hearth' (HEARTH_LIGHT_RADIUS=5)
- World.light_sources registry + register/unregister + is_tile_lit(tile)
(Manhattan distance, no occlusion — Phase 13 may add wall-occlusion)
CanvasModulate darkness + in_darkness thought (Agent C, ~30 lines mod +
new factory):
- DarkOverlay CanvasModulate node added to world.tscn (first child of
World root so it tints all sibling layers + entities)
- world.gd._update_dark_overlay lerps DAY_TINT (white) ↔ NIGHT_TINT
(0.20, 0.22, 0.40 deep cool blue) by Clock.darkness_factor() each tick
- ThoughtCatalog.in_darkness(): persistent, -3 mood, fires when
darkness > 0.3 AND World.is_tile_lit(pawn.tile) is false
- Pawn._process_thoughts syncs in_darkness alongside hungry/tired
Opus integration:
- project.godot: Clock autoload registered
- world.tscn: DarkOverlay CanvasModulate node, plus the agent additions
- Demo seed: 2 torches inside cabin at (46, 26) + (49, 26), pre-built
- MCP-driven runtime test verified day→night transition + lighting
effects:
- Noon: world bright green, torches barely visible (over-bright at noon
is minor polish — Phase 17 may scale torch energy by darkness)
- Midnight: world deep blue/green tinted, torches cast yellow halos,
Hearth ember glows orange, cabin interior warmly lit, exterior dark
- top_bar clock label updates each sim tick (early-out on no-change)
Phase 11 followups for later phases:
- Torch energy should scale with darkness — visible halos at noon are
silly. Phase 17 will likely tie PointLight2D.energy to clamp(darkness,
0.2, 1.0) so they're invisible at midday
- Wall-occlusion for light_map — Phase 13's room-detection BFS could
treat completed wall tiles as occluders so light doesn't bleed through
- 'In darkness' thought currently treats ALL unlit cells as darkness;
Phase 13's roof flag could differentiate 'indoors-dark' (different
thought) from 'outdoors-dark'
- Light source visibility through CanvasModulate works correctly thanks
to PointLight2D's additive blend mode
Acceptance — MCP-verified via play_scene + get_game_screenshot:
- ✅ Day → Dusk → Night cycle visible (Clock.current_phase emits events)
- ✅ CanvasModulate tints world deep blue at night
- ✅ Torches cast visible yellow halos via PointLight2D additive blend
- ✅ Hearth opts-in as a light source via label_text='Hearth' check
- ✅ Top-bar clock shows 'Day N, HH:MM' format and updates each tick
- ✅ in_darkness thought wires through _process_thoughts (would fire if
a pawn were standing in an unlit night tile — demo didn't capture this
specifically but the code path is verified)
Delegation report this phase:
- Agent A: Clock autoload + 4-phase day cycle + top-bar UI extension
- Agent B: Torch entity + PointLight2D + procedural radial texture +
Workbench Hearth opt-in + World.light_sources registry
- Agent C: CanvasModulate world.tscn node + day/night colour lerp +
in_darkness ThoughtCatalog entry + Pawn persistent thought sync
- Opus: Clock autoload registration in project.godot + 2 torches in
demo seed + MCP runtime verification at midnight vs noon
~75% of Phase 11 GDScript was subagent-authored.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Three gdscript-refactor agents in parallel; Opus integrated and tuned
the priority + hunger-decay numbers via MCP runtime observation.
Crop entity + PlantProvider (Agent A, scenes/entities/crop.{gd,tscn} +
scenes/ai/plant_provider.gd, ~225 lines):
- Crop: 6-stage state machine (TILLED → SOWN → GROWING_1/2/3 → READY).
STAGE_TICKS=200 sim ticks per stage × 4 stages = 800 total to maturity.
Listens to EventBus.sim_tick for growth. Procedural _draw with growing
plant + ready-state golden grain accent.
- on_harvest_tick: drops a grain (wheat) or vegetable (potato) Item, resets
to TILLED (re-sowable).
- on_sow_tick: TILLED → SOWN — used when Phase 17 paint UI lands.
- PlantProvider priority=5 (above crafting=4) — harvest-only for Phase 7.
Sow returns null to avoid the infinite harvest+sow loop that would
starve crafting forever.
- JobRunner._tick_interact extended with is_harvestable/is_sowable probes
alongside existing is_choppable/is_mineable. Unified probe array.
Hunger + Eating (Agent B, scenes/pawn/pawn.gd + scenes/ai/eat_provider.gd +
toil.gd/job_runner.gd extensions, ~150 lines):
- Pawn.hunger: float 0..100. HUNGER_DECAY_PER_TICK=0.02 (tuned down 5×
from agent's 0.10 after MCP runtime test showed pawns starving before
cooking pipeline could finish — 0.02 means 100→0 in 5000 ticks =
~4 min at 1× / ~20s at Ultra).
- is_hungry() at <30 — triggers EatProvider job
- is_starving() at <5 — Phase 9 status-interrupt hook reserved
- Toil.KIND_EAT + JobRunner._tick_eat — consumes carried_item, applies
nutrition bonus by type (MEAL +60, BREAD +45, VEGETABLE +25, GRAIN +10)
- EatProvider priority=7 (highest) — food-priority ladder:
MEAL > BREAD > VEGETABLE > GRAIN
- Pawn.skills extended with cooking init; hunger round-trip in to_dict
Cooking recipes (Agent C, recipe_catalog.gd + item.gd + workbench.gd
draw extensions, ~120 lines):
- New Item types: TYPE_FLOUR, TYPE_BREAD (TYPE_MEAL was already in base
16-chip set)
- RecipeCatalog adds:
* flour() — grain → flour, Crafting skill, 50 ticks
* bread() — flour → bread, Cooking skill, 90 ticks
* meal_from_vegetables() — vegetable → meal, Cooking, 80 ticks
- Workbench._draw extends label_text dispatch:
* Hearth: dark stone + large orange flame + smoke wisp
* Millstone: light grey + dark circular stone wheel
- i18n: item.flour, item.bread, item.meal, workbench.hearth, workbench.millstone
Opus integration:
- world.tscn: PlantProvider + EatProvider nodes (8 providers total)
- world.gd registers all 8 in priority order:
eat=7 > construction=6 > chop=5 > plant=5 > mine=4 > crafting=4 >
haul=3 > rest=0
- Pawn spawn data extended with cooking skill (Bram=2 / Cora=6 / Edda=1)
for hearth-recipe quality spread
- _seed_phase5_demo_buildings extended (now spans Phase 5/6/7):
- Millstone at (46, 27) inside cabin south-row: flour bill FOREVER
- Hearth at (49, 27) inside cabin south-row: bread + meal bills FOREVER
- 6 wheat crops east of cabin at (54-55, 24-26), all SOWN at boot
- 2 pre-baked breads at (45-50, 21) so eat-loop unblocks before cooking
chain completes
Wall-trap fix from Phase 6 confirmed working — pawn paths now go to
(44, 29) adjacent to the south-west corner wall, not on top of it.
Acceptance — MCP-verified end-to-end:
- 6 wheat crops grow over ~800 sim ticks; PlantProvider picks them up
- Pawns harvest all 6 → 6 grain items dropped (PlantProvider priority 5
> Crafting priority 4 means harvest interrupts plank crafting)
- Hunger decays steadily; at <30 EatProvider takes over (priority 7
beats all work providers)
- 2 pre-baked breads consumed first (priority 2 > grain priority 0)
- Pawns then ate the raw grain (priority 0 last resort) before flour
could be milled — this is by-design 'starving pawn settles for raw'
behaviour, not a bug. Phase 17 balance pass may add a wait-for-cooked
preference if it feels wrong in playtest.
- Planks crafted with EXCELLENT quality at (46, 25) — quality system from
Phase 6 still works on top of the new pipeline
Phase 7 tuning lessons (logged):
- Agent's initial 0.10/tick hunger decay made pawns starve in <60 sim
seconds — too fast for any multi-step chain (grain→flour→bread is
~140 sim ticks per cycle). Tuned to 0.02/tick post-runtime.
- PlantProvider's sow+harvest both returning jobs caused infinite plant
loops at priority 5. Sow returns null until Phase 17 splits the
providers or adds designation-paint sow.
- The 'raw grain eaten before flour milled' isn't a bug — it's the food
priority ladder doing its job. To showcase the full chain in a demo,
either reduce hunger decay further or pre-seed cooked food.
Delegation report this phase:
- Agent A: Crop entity + PlantProvider + JobRunner probe extension
- Agent B: Pawn.hunger + EatProvider + KIND_EAT toil
- Agent C: Recipe catalog extension (flour/bread/meal) + Workbench draw
branches for Hearth/Millstone
- Opus: scene wiring + pawn cooking-skill init + demo seed (Millstone +
Hearth + 6 crops + pre-baked breads) + MCP-driven runtime tuning of
hunger decay and plant priority
~75% of Phase 7 GDScript was subagent-authored.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Three gdscript-refactor agents in parallel; Opus did integration + caught
the wall-trap bug via MCP runtime test.
Data layer (Agent A):
- scenes/ai/recipe.gd: class Recipe (RefCounted) — id, ingredient_type,
output_type, work_ticks, required_skill (Crafting/Cooking), skill_threshold
- scenes/ai/bill.gd: class Bill — Mode enum (FOREVER/COUNT/UNTIL_N),
recipe ref, target_count, completed_count, paused, is_active() per-mode
logic. UNTIL_N walks World.items each call (acceptable at MVP scale; cache
if items grow large in Phase 16+)
- scenes/ai/recipe_catalog.gd: RecipeCatalog.plank() / .stone_block() — 2
starter recipes; Phase 7+ expands toward the design.md ~22 catalog
- Item: added Quality enum (SHODDY/NORMAL/EXCELLENT/MASTERWORK/LEGENDARY),
@export quality field, quality-coloured border in _draw (dull-grey / no /
blue / gold / magenta), TYPE_PLANK + TYPE_STONE_BLOCK constants
- Pawn: added skills dict (5 skills × levels 0–10), get_skill/set_skill,
skills round-trip in to_dict/from_dict
- strings.gd: item.plank, item.stone_block, quality.* (5 keys)
Workbench entity (Agent B, scenes/entities/workbench.{gd,tscn}, ~310 lines):
- class Workbench extends Node2D, bottom-anchored 3/4 perspective like Wall
- BuildJob interface (is_buildable / on_build_tick / _complete) — same
pattern as Wall / Crate
- Bills queue (add_bill, find_active_bill matches by accepted_skill)
- Craft cycle hooks: begin_craft / tick_craft / on_craft_complete /
on_craft_interrupted — JobRunner._tick_craft delegates to these
- Procedural _draw differentiates Carpenter (brown bench + vise) vs
Smelter (dark stone + orange ember glow) via the @export label_text
field — no subclass needed for Phase 6
- World autoload: workbenches registry + register_workbench/unregister_workbench
Crafting AI (Agent C):
- Toil.KIND_CRAFT + Toil.craft_at(workbench_path, bill_index) factory
- JobRunner._tick_craft: validates pawn-at-workbench, ingredient match;
delegates progress to wb.tick_craft; on complete spawns output Item
with QualityCalc.roll() applied; records bill completion
- crafting_provider.gd: priority=4 WorkProvider, 4-toil job
(walk_to(ingredient) → pickup → walk_to(wb) → craft_at)
- quality.gd: QualityCalc.roll(skill) — additive formula
skill × 0.04 + RNG(0, 0.6) with bucket thresholds matching
architecture.md spec. Skill 0 caps at Excellent; Skill 10 reaches
Legendary ~8% of the time
Opus integration:
- world.tscn: CraftingProvider node added
- world.gd: registered crafting_provider with World (priority order:
construction=6 > chop=5 > mine=4 > crafting=4 > haul=3 > rest=0)
- Pawn spawn data extended with crafting skill (Bram=8, Cora=4, Edda=0)
for visible quality variation in the demo
- _seed_phase5_demo_buildings extended: pre-built Carpenter at (46, 25)
with plank bill (FOREVER) + Smelter at (48, 25) with stone_block bill
(UNTIL_N=5)
The wall-trap bug (caught via MCP runtime — initial Phase 6 run hung):
- Pawns building walls stood ON the wall tile. When wall._complete fired
set_cell_walkable(false), the pawn was stuck on a solid cell.
AStarGrid2D returns no path when start cell is solid → all subsequent
jobs failed pathfinding from the trapped position.
- Fix: ConstructionProvider checks site.blocks_pathing_when_complete()
(new method on Wall, returns true; not implemented on Floor/Door/Crate/
Workbench since they remain walkable). Walls route the pawn to an
adjacent walkable cell via _find_adjacent_walkable. Floors/doors/etc.
build on-tile as before.
- This bug existed since Phase 5 but only surfaced in Phase 6 because
Phase 5 demos ended at construction-complete; Phase 6 needed pawns to
walk away from finished walls toward the workbench.
Acceptance — MCP-verified end-to-end:
- 3 pawns boot with varied Crafting skills
- Construction priority wins first; all 48 build sites (23 walls + 1 door
+ 24 floors) complete. Pawns escape wall tiles safely (fix verified).
- Pawns transition to chop/mine, then crafting at the Carpenter workbench
- At tick 9215, 12 planks crafted with quality distribution matching
expected spread per skill: 1 SHODDY + 6 NORMAL + 4 EXCELLENT + 1
MASTERWORK. Quality-coloured borders visible on items.
- Smelter UNTIL_N=5 bill correctly idle (no stone consumed yet) because
CraftingProvider prefers closer workbench-ingredient pairs and the
carpenter+wood is closer to where pawns end up than smelter+stone
Phase 6 followups for later phases:
- on_craft_interrupted has no JobRunner hook — Phase 9 status interrupts
will need a 'cancel callback' on toils or wb.on_craft_interrupted will
leak current_bill/current_work_progress on canceled crafts
- Bill.from_dict reconstructs Recipe inline via Recipe.from_dict — Phase
16 may need a recipe registry for save-format stability across catalog
changes
- UNTIL_N's per-call World.items walk is O(items) — acceptable at MVP
scale; profile if it becomes hot
Delegation report this phase:
- Agent A: Recipe + Bill + RecipeCatalog + Item.quality + Pawn.skills + i18n
- Agent B: Workbench (one class, label_text-driven differentiation, no
Carpenter/Smelter subclass) + World registry
- Agent C: Toil.KIND_CRAFT + JobRunner._tick_craft + CraftingProvider +
QualityCalc
- Opus: scene wiring + pawn-skill init + workbench demo seed + wall-trap
fix (caught via MCP) + runtime verification
~75% of Phase 6 GDScript was subagent-authored.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Three gdscript-refactor agents in parallel + Opus integration.
Entities (scenes/entities/, Agent A — 3 scripts + 3 .tscn, ~460 lines):
- item.gd: 16-type StringName registry (matches design.md filter chips);
Node2D + _draw() colored square + stack-count badge; to_dict/from_dict
- tree.gd: class_name HarvestableTree (Godot 4 ships a built-in 'Tree'
Control class — renamed to avoid the shadow); CHOP_TICKS=80; on_chop_tick
advances progress, fells when complete, drops 3 wood items at tile +
walkable neighbours
- rock.gd: MINE_TICKS=120; angular polygon _draw; mined() drops 1 stone
Toil + provider extensions (scenes/ai/, Agent B — 4 files modified/added,
~250 lines):
- Toil: new KIND_INTERACT (timed entity action), KIND_PICKUP, KIND_DEPOSIT
- JobRunner: _tick_interact resolves NodePath, calls target.<method>()
each tick, marks done when is_choppable/is_mineable returns false;
_tick_pickup finds Item at pawn.tile, transfers to pawn.carried_item;
_tick_deposit places carried_item at pawn.tile + clears the
items_needing_haul dirty flag
- ChopProvider (priority=5): nearest choppable tree; Job=[walk_to + interact]
- MineProvider (priority=4): same for rocks
Hauling system (scenes/world/ + scenes/ai/, Agent C — 4 files, ~330 lines):
- StorageDestination: abstract Node2D base; Priority enum CRITICAL=0..OFF=4;
accepted_types (empty=wildcard); _filter_accepts() helper
- StockpileZone: concrete rect-region zone; _draw paints priority-tinted
overlay (z_index=-1); find_drop_position scans for free cells respecting
one-stack-per-tile rule
- HaulingProvider (priority=3): nearest dirty item × best destination →
4-toil job [walk → pickup → walk → deposit]; sweep_for_better_destinations
enables the priority cascade (items in lower-priority zones re-mark dirty
when a higher-priority destination opens up)
Opus integration (~200 lines):
- World autoload: trees/rocks/items/items_needing_haul/stockpiles registries
+ register/unregister methods; pathfinder reference exposed for entity
code (tree.fell needs is_walkable for neighbour drops)
- Pawn: carried_item slot + carry-indicator (small colored rect upper-right
of body) via queue_redraw in _on_sim_tick
- World scene: registers chop/mine/haul/rest providers; spawns 6 trees
(cluster east-north), 4 rocks (south-east), 2 stockpile zones (Zone A
wood-only NORMAL, Zone B wildcard HIGH); periodic
hauling_provider.sweep_for_better_destinations every 100 sim ticks
Acceptance — MCP-verified end-to-end (the full Phase 4 loop):
- 3 pawns boot, Decision picks chop (highest priority work), all walk to
nearest tree, chop in parallel (3× speed because all 3 call on_chop_tick
per tick). Trees fell, drop wood (18 items). Pawns move to rocks, mine,
drop stone (4 items). Total 22 items spawn.
- HaulingProvider routes wood + stone toward Zone B (wildcard HIGH > Zone
A's wood-only NORMAL). Pawns carry items one at a time, visual indicator
shows during transit. Items deposit, items_needing_haul dirty flag
clears.
- **Priority cascade test:** Zone A promoted from NORMAL to CRITICAL.
Manually-triggered sweep marks 3 wood items in Zone B for re-haul.
Within a few thousand ticks: Zone A has 5 wood (cascaded from Zone B),
Zone B has 4 stone only (wood left, stone stayed because Zone A rejects
stone). Filter + priority cascade working exactly per design.md spec.
Phase 4 gotchas (logged in implementation.md):
- 'Tree' shadows Godot 4's built-in Tree Control class — class_name had to
be renamed to HarvestableTree. Scene/file names stayed as 'tree' since
the game concept is still 'tree'; the rename only affects code-side
type references.
- draw_colored_polygon(points, color) takes a SINGLE Color, not a
PackedColorArray. Agent C had to be reminded; draw_polygon(points, colors)
is the variant that takes per-vertex colors.
- Godot's class-name cache lags behind file changes — a full editor scan
('godot --headless --editor --quit') is needed to flush. Even after
reload_project, type-annotation assignments can fail; duck-typed
variables ('var x = scene.instantiate()') sidestep the issue.
- JobRunner's _tick_deposit had to explicitly call
World.clear_item_haul_flag — the dirty set persisted otherwise and
items appeared 'needing haul' even after deposit.
Delegation report this phase:
- Agent A (Sonnet, gdscript-refactor): Tree + Rock + Item entities + i18n
keys. ~460 lines.
- Agent B (Sonnet, gdscript-refactor): Toil extensions + JobRunner handlers
+ ChopProvider + MineProvider. ~250 lines.
- Agent C (Sonnet, gdscript-refactor): StorageDestination + StockpileZone
+ HaulingProvider with cascade sweep. ~330 lines.
- Opus: World autoload extensions (entity registries + pathfinder ref),
Pawn carry slot + visual, world.tscn/gd wiring, the Tree rename, the
draw_colored_polygon fix, the dirty-set-clear fix, MCP-driven runtime
verification including the full chop-mine-haul loop and the priority
cascade demo.
~75% of Phase 4's GDScript was subagent-authored.

AI core (scenes/ai/, 5 new files from 3 gdscript-refactor agents in parallel):
- job.gd (59 lines, Agent A): Job class, RefCounted, label + toils + cursor +
to_dict/from_dict round-trip
- toil.gd (76 lines, Agent A): Toil class, RefCounted; kinds WALK/WAIT/IDLE;
factories walk_to/wait_ticks/idle; Vector2i stored as to_x/to_y ints
because Godot 4 JSON.stringify doesn't round-trip Vector2i
- work_provider.gd (27 lines, Agent A): abstract base, class_name, @export
category/priority, find_best_for() with push_error subclass guard
- job_runner.gd (186 lines, Agent B): Node-derived runner; setup/start_job/
cancel_job/tick; WALK toil delegates to pawn.walk_along_path on first
encounter (sets data.started=true), listens for walk_completed signal;
WAIT decrements ticks_remaining; IDLE never completes; full to_dict/from_dict
- decision.gd (50 lines, Agent C): static pick_next_job(pawn, providers); 5
layers (incapacitation/forced/status/work/idle); layer 1 probes via
has_method to stay future-proof for Phase 9
- rest_provider.gd (31 lines, Agent C): extends WorkProvider; @export rest_tile;
returns [walk_to(rest_tile), idle()] Job
Integration (Opus):
- pawn.gd: added forced_job slot, job_runner ref, _orchestrate_ai called
before _advance_walk on each sim_tick. Calls Decision when forced_job is
queued OR when idle — was a bug initially (only-on-idle never preempted
the never-completing IDLE toil); fixed and caught via MCP runtime test.
Added to_dict/from_dict for save round-trip; captures tile, _path,
_step_progress, _selected, forced_job, job_runner via their serializers.
- selection.gd: rewrote to build a forced-job [walk_to + idle] and set
pawn.forced_job; Decision preempts current job on next tick.
- world.tscn/gd: instantiates RestProvider as child (rest_tile = (50,50)
just outside the stone ring's south-east, reachable from all 3 spawn
tiles); registers via World.register_work_provider; attaches a JobRunner
child to each spawned pawn and wires setup(pawn, pathfinder).
- world.gd autoload: added work_providers list + register/clear methods.
- save_system.gd: write_save walks World.pawns calling to_dict; apply_save
zips dicts to pawns by index (Phase 16 will add stable IDs).
- main.gd: bootstrap log line bumped Phase 2 → Phase 3.
Acceptance — MCP-verified end-to-end:
- 3 pawns boot, Decision assigns each Rest, JobRunner starts each,
all 3 walk to (50,50) on different paths (40/35/30 steps based on
detour around the stone ring), arrive and idle.
- Force Bram to (10,10) via pawn.forced_job; preempt fires:
[decision] Bram: forced 'Go to (10, 10)'. Bram walks while Cora/Edda
stay parked.
- Mid-walk save round-trip (the critical Phase 3 acceptance):
- Paused Bram at (51,10) walking to (70,70) with 79 path steps remaining
- SaveSystem.write_save() → SaveSystem.apply_save(read_save()) after a
mutate-to-(0,0)-with-no-path round-trip
- Restored Bram exactly: tile=(51,10), _path.size=79, walking=true,
job='Go to (70, 70)' at toil_idx=0 (WALK toil with data.started=true)
- Resumed sim → JobRunner's WALK toil saw started=true and did NOT
re-call walk_along_path; the pawn's restored _path continued the walk
naturally → reached (70,26) with 44 steps remaining, still on the
same job. The architecture.md 'mid-toil suspend safe' contract is
provably honored.
Phase 3 gotchas (logged in implementation.md):
- Class-name registration timing bit again (Phase 2 gotcha). Workflow:
agent writes class_name file → MCP reload_project → headless validate.
- Forced-job preempt requires triggering Decision when forced_job != null,
not just when idle (IDLE toil never completes).
- execute_game_script + await Engine.get_main_loop().process_frame is
flaky — MCP auto-recovers but the script's last lines may be lost.
Workaround: split state-inspection into a fresh execute_game_script.
Delegation report this phase:
- gdscript-refactor (Sonnet) Agent A: Job + Toil + WorkProvider abstract
base. 3 files, 162 lines.
- gdscript-refactor (Sonnet) Agent B: JobRunner with toil-execution match
+ walk_completed signal handling + full save round-trip. 1 file, 186
lines.
- gdscript-refactor (Sonnet) Agent C: Decision pipeline + RestProvider.
2 files, 81 lines.
- Opus: Pawn integration (forced_job slot, orchestration, to_dict/from_dict),
Selection rewrite, world.tscn/gd wiring, World autoload work_providers
list, SaveSystem extension, MCP-driven runtime verification including
the mid-walk save round-trip demo, gotcha logging.
~70% of Phase 3's GDScript was written by subagents.

Pawn (scenes/pawn/{tscn,gd}, ~108 lines, gdscript-refactor agent):
- Node2D root (no physics — grid-snapped lerped motion); name + state labels
- _draw() paints body disc with hue derived from name.hash(), dark outline,
yellow selection ring when selected
- Clock = EventBus.sim_tick: each tick advances _step_progress by 1/10;
at 1.0 snaps tile to next waypoint, pops path. STEP_TICKS = 10 →
1 tile / 0.5 s at 1×, scales with Sim speed for free (pause/Fast/Ultra)
- _process() lerps render position between current and next tile every
render frame for smooth visual between sim ticks
- Public API: setup, walk_along_path, is_walking, set_selected,
signals walk_started/walk_completed/arrived_at_destination
Pathfinder (scenes/world/pathfinder.gd, ~110 lines, gdscript-refactor agent):
- AStarGrid2D wrapper, 80² region, DIAGONAL_MODE_NEVER (Rimworld
4-directional), Manhattan heuristic
- API: setup, set_cell_walkable (emits walkability_changed signal),
is_walkable, find_path (excludes start tile, includes end), benchmark
- find_path returns empty Array[Vector2i] for OOB endpoints, solid
destination, or disconnected areas
Selection (scenes/world/selection.gd, ~85 lines, Opus):
- Lives as a Node child of World; _unhandled_input handles mouse clicks
- Click-vs-drag discrimination: 8 px max drift + 300 ms max duration →
drags belong to the camera, only true clicks select/command
- Click on pawn → select (yellow ring); click on walkable empty tile
with a pawn selected → pathfinder.find_path + pawn.walk_along_path
World autoload (autoload/world.gd):
- Added pawn registry: register_pawn, unregister_pawn, pawn_at_tile, clear_pawns
- Untyped Array (Array[Pawn] hits Godot's class_name-not-yet-registered
timing in autoload init; duck typing fine for current consumers)
World scene (scenes/world/{tscn,gd}):
- Pathfinder + Selection nodes added as children
- _ready() wires: pathfinder.setup(MAP_SIZE_TILES), walls → pathfinder
(28 cells from 8×8 stone ring marked impassable), selection.bind(pathfinder),
spawns 3 pawns (Bram/Cora/Edda) at (20/25/30, 40), runs spike benchmark
- main.gd bootstrap line bumped Phase 1 → Phase 2
i18n: 2 new keys (pawn.state.idle, pawn.state.walking)
Spike result — AStarGrid2D path-query timing at 80²:
- 36 paths (all 4-corner pairs × 3 iterations)
- min 6 μs, avg 9.1 μs, max 18 μs
- ~55× faster than the 'sub-millisecond' target in architecture.md
MCP runtime verification:
- play_scene → 3 pawns visible with distinct hashed-hue body colours
- execute_game_script: pathfinder.find_path((20,40)→(50,40)) returns
38-step path (30 straight + 8 detour around the ring)
- bram.walk_along_path(path) → screenshot caught him mid-walk on south
side of ring with state='walking' + selection ring visible
- arrival snapshot: state='idle'
Phase 2 gotcha (documented in implementation.md): class_name registration
happens at editor scan-time, not headless-load-time. First headless run
after authoring class_name files fails until reload_project rebuilds the
global class cache. Workflow: agent writes → MCP reload_project → headless
validate. Documented for future phases.
Delegation report this phase:
- gdscript-refactor (Sonnet) #1: Pawn class — scene, script, draw logic,
movement loop, i18n keys. ~108 lines pawn.gd + 22 lines pawn.tscn.
Headless-validated by the subagent (note: validated before world.gd's
Pawn reference was added).
- gdscript-refactor (Sonnet) #2: Pathfinder class — AStarGrid2D wrapper,
4-dir Manhattan, benchmark utility. ~110 lines pathfinder.gd. Headless-
validated by the subagent.
- Opus: Selection module + World autoload registry + scene integration
(world.tscn/gd) + MCP-driven runtime verification + spike benchmark
+ class_name workflow gotcha documentation.
