- shared/protocol.ts: TurnResult.unowned (keys released this turn) + the map presentation contract (regionFillStyle / unownedTooltipLabel, hue-less grey) - shared/types.ts: required GameState.unowned (cumulative mid-game releases; [] at init, distinct from preset-unassigned regions) - server/engine.ts: applyTurnResult applies releases first (sole-owner only, never fabricating no man's land from unassigned keys), then claims against the post-release snapshot (gain on an ownerless key = re-claim); lone release is isMeaningful; prompts + user payload carry the unowned field - server/stub.ts: unchanged behavior (never releases; e2e stays stable) - server/db.ts: legacy rows load with unowned defaulted to [] - server/index.ts: create-game sets []; jump reference table includes released keys so the model can name them for re-claim - WorldMap/App: unowned prop -> visible grey + 'No man's land' tooltip - unit tests: 105 -> 127 (release/re-claim suites, presentation contract, legacy-row normalization)
