# VERTICAL SLICE - NOT FOR PRODUCTION
# 日志 step 行零文案与全字段落盘断言（结算期文字列表退役批 T2——日志零文案只存字段）：
# 真实入口 = sim 采集链（LevelAutoplay.run_level 挂 PlaytestLogger.start_session → 真实结算 →
# close_session 落盘 JSONL 读回），断言：
# ① 全型 step 行零中文文案（text / display_name 两键不存在）；
# ② 公共七字段（kind/type/source/cell/round/value/highlight）与平铺原件（origin_cell/round_index/
#    source_class）逐型在位——日志逐行全字段落盘义务不变（公共字段集除文案两键外零删减）；
# ③ payload 键抽样在位（damage 行 roll/ac/tier/normal/pierce/magic/baseline——改前键集实证在册，
#    反事实精确重算数据面不被零文案改动静默吞键）。
# 运行：godot --headless --path game --script res://tests/unit/presentation/playtest_logger_step_fields_test.gd（expect 0）
