Summary by CodeRabbit

  • Bug Fixes
    • Movement predictions are skipped when a destination and all eight in-bounds surrounding cells belong to the same enemy country. Map edges count as exits, and unowned cells are not treated as enemy territory.
    • Publish updates send movement data before country ownership snapshots, helping keep displayed movement and territory information consistent.

📝 Walkthrough

Movement predictions now skip destinations surrounded by one enemy country. Publish batches now set user chunks before country chunks.

Changes: Cordon-Off Movement and Publishing

Layer / File(s) Summary
Enemy-surrounded movement predictions
examples/cordon-off/shared.ts, examples/cordon-off/client.ts, examples/cordon-off/paint.test.ts
movementPaints uses an ownership lookup to skip predictions when the destination and all eight in-bounds neighbors have the same enemy owner. Map edges provide exits. Tests cover fully surrounded and unowned destinations, map edges, poles, and existing movement behavior.
User-chunk publish ordering
examples/cordon-off/publish.ts, examples/cordon-off/publish.test.ts
Publish operations now set user chunks before country chunks. A test checks the order when both chunk types are dirty.

- Line 295: Update the wrapped-neighbor check around ownerAt so destinations at
x === 0 or x === WIDTH - 1 return false instead of being suppressed by
horizontal wrapping. Change the seam test to expect a paint for those
destinations.
