# tests/integration/save_rng_roundtrip_test.gd — L2 集成用例：存档 ⇄ RNG 快照往返
|
|
# 跨系统面 = SaveManager（落盘 + 版本迁移链）× AdventureRunner（断点消费）×
|
|
# RngService（种子/取数号位续跑）× BoardGenerator（开板确定性）。
|
|
# 与 tests/unit/core/breakpoint_resume_test.gd 的分工：那件是单测，只验「断点写读 + 首战开板一致」；
|
|
# 本件验的是**跨系统闭环**——盘上往返（含旧版本档经迁移链）之后，断点仍能被冒险层消费且 RNG 续跑
|
|
# 零跳号，是「玩家的旧存档还能不能接着打」这条真实路径。
|
|
# 运行：godot --headless --path game --script res://tests/integration/save_rng_roundtrip_test.gd
