# tests/unit/battle_settlement/settlement_wiring_snapshot_test.gd — 结算接线同种子逐项 golden 对拍宿主（架构审查 5.1 封装修复批 R1 主证）
# 断言面 = 同种子定死驱动序下 step_row 全量行流 ＋ settlement_snapshot 全量载荷 ＋ battle_finished
# 载荷 ＋ 收束 presentation_snapshot 关键键（round/battle_result/hero.hp/enemies.size()），
# 与 GOLDEN 常量逐位相等〔封装5.1 V1〕——段类束注入改造的零行为变更主证：
# 改前基线在未改树上固化（GOLDEN 为空时走转储通道取数），改后全程保持绿。
# 驱动序（卡面逐字定死）：begin_battle(voucher_rap=20) → 轮1 choose_dig 移动/挖/封邻格/停 →
# player_request_refresh（换图刷新链入流）→ 轮2 一挖一停 → 轮3 径直停手。
# 协议照单元侧惯例：extends SceneTree＋Kit.check 主通道；--script 模式无 autoload，
# ConfigDB 显式实例化构造注入＋自建 RngService（掷点隔离形态）。
# 取数通道：GOLDEN 为空时打印捕获序列 JSON（两格缩进）后按专用码 3 退出——非判定码族（0 绿/1 红/2 空跑）。
# 运行：godot --headless --path game --script res://tests/unit/battle_settlement/settlement_wiring_snapshot_test.gd
