BoardState.CaptureSave/RestoreFromSave deep-copy every mutable field
(grid, pieces, demands, transformers, buffers, stock, campaign progress)
into a WorldSave slot. GameSim.QuickSave/QuickLoad expose slotted saves
and emit StateSavedEvent / StateRestoredEvent — the latter carries a
fresh BoardSnapshot so the presentation can rebuild board, pieces,
trajectories, objectives, stock, camera, and control bar in one pass.
F5/F9 trigger it in Main; harness gains quick_save/quick_load commands so
UI tests can checkpoint a scenario and resume without replaying from
scratch. Seven xUnit tests cover the roundtrip (including independence
from post-save mutations, campaign state, and multi-slot isolation).
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.
- Fix cargo bouncing in relay chains: piece-to-piece transfers now prefer
receivers farther from production (forward flow) instead of closer (backward)
- Level 2 stock corrected: 4R+1B → 6R+1B to match required solution
- Level 3 simplified to single cargo type (6R+1K) — dual-cargo on 6x6
requires engine support for cargo-type filtering (Phase 2)
- Add PLAN.md with prototype roadmap (phases 2-6)
- 57 tests passing
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.
