Phase 7 — Crops, hunger, eating, cooking chain (grain → flour → bread)

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.
