约定仓库忽略构建产物，并固定代理协作边界。

核心不得依赖引擎界面，随机数走统一入口，避免规则写进表现层。

+# Agent rules
+
+Read `docs/FOUNDATION.md` and `docs/ARCHITECTURE.md` before large refactors.
+
+- `Game.Core` must not depend on Godot.
+- All randomness must go through `GameRng`. Simulation and presentation share one rules engine.
+- UI must not implement game rules. Presentation renders `GameState` and plays `GameEvent`s.
+- Adding or changing core rules requires adding or updating tests.
+- Ordinary cards should use standard effects. Do not invent a general-purpose scripting language.
+- Changing the content schema requires updating the validator and `docs/CONTENT_SCHEMA.md`.
+- Changing event resolution order requires checking related tests.
+- Do not create a global rule for a single card.
+- Prefer the smallest working implementation. Do not optimize until there is a measured bottleneck.
+- Freeze the 11 core actions in `docs/RULES.md`. New “archetypes” are combinations, conditions, or keywords — not new primitive events.
+- Card packs are **in-run only**. Unlock state must reset with the run. Do not add cross-run / meta unlocks.
