DemandDef gains optional ConsumptionPerTurn and SustainTurns. When
ConsumptionPerTurn > 0 the demand maintains a buffer filled by
deliveries and drained each turn. Shortage fires the first turn the
buffer can't cover consumption; it clears when the buffer refills.
SustainedTurns counts consecutive non-shortage turns, and IsSatisfied
flips to true once it meets SustainTurns — so the victory condition
becomes "no shortage for N consecutive turns" as soon as a mission opts
in. Classic demands (ConsumptionPerTurn = 0) behave exactly as before.
TurnExecutor runs the consumption sub-phase after transfers. Two new
events (DemandShortageStarted / DemandShortageCleared) let the
presentation surface the state later. BoardSnapshot + CampaignLoader
carry the new fields; no existing mission opts in yet, so
campaign_01.json is unaffected.
Bundles in-flight work on the campaign/missions system (CampaignDef,
MissionDef, TerrainPatch, TransformerDef, MissionChecker, CampaignLoader,
FlavorBanner, transformer rules), plan files, and matching tests. Baseline
commit so the upcoming automation testing harness lands on a clean tree.
- New turn order: produce -> transfer -> move -> collision resolution
- Collisions now destroy weaker pieces (status > level > mutual destruction)
instead of halting the simulation. SimPhase.Collision removed.
- Add piece Level property (all level 1 in proto, prepared for future)
- Production fires every turn (interval concept removed), buffer = Amount
(default 1, future 2-4), leftovers overwritten each turn
- Transfer tiebreaker: status > level > clockwise direction (alternating
even/odd turns in y-up coords), replaces distance-to-production
- Demands always accept matching cargo even when already satisfied
- TurnNumber added to all turn events for animation grouping
- Simultaneous animations: produce flash, cargo slide, parallel piece moves
- Camera centering fix + middle-click pan
- GDD updated with new rules + lore section added

Add CargoFilter property to PieceState, auto-assigned at placement
by tracing relay chain back to production. TransferResolver now
enforces cargo-type filtering and uses forward-direction sorting
with cargo-aware distance calculations. Prevents cross-route
contamination on multi-cargo boards.
Level 3 restored to dual-cargo (Wood+Stone) with correct 10R+2K stock.
Two new solvability tests validate filter auto-assignment and chain
propagation. All 60 tests green.
Black box sim engine (commands in, events out) with 3 piece types
(Rook, Bishop, Knight), cargo transfer system with social status
priority, collision detection, and victory/defeat conditions.
57 tests covering rules, simulation, loading, and solvability.
Godot 4 presentation layer scaffolding.
