/**
 * 《深海回音》R3 无头试玩仿真测试（26 号 playbook 深度重构版）。
 *
 * 方案：
 * - mock 浏览器环境：window/localStorage/navigator/fetch/AudioContext
 *   （decodeAudioData 返回固定 2.0s 时长的假 buffer，语音链靠引擎 endTimer +
 *   onComplete / Floor 轮询推进，虚拟时钟驱动，不真实等待）；缺失 voice 资产
 *   按可用处理（流程测试与 TTS 资产生成解耦，资产品质由文末「资产引用校验」
 *   单独把关，新台词 id 允许待生成）；强制 404（blockedAssets）走 Floor 单句
 *   看门狗自动续链（引擎 §4.1 缺失资产兜底）。
 * - 使用**真实** engine/audio.js + settings.js + pipeline.js + floor/hints/
 *   confusion/novice/receipts 全六模块；手势走 makeInputPipeline（与
 *   index.html 同构，doubleTapWindow=0 语义由管道内折算等价覆盖）。
 * - 虚拟时钟：patch setTimeout/clearTimeout/performance.now；环境音循环为
 *   buffer.loop 句柄（无重触发定时器），全程可空闲、可复现。
 *
 * 覆盖（17 号附录 C §10 + 26 号 §6）：
 * - §4.10 首 3 分钟：3 秒内第一次操作、第一次成功（ok 回执）、开场规则念白废除；
 * - 玩法核心：剧本 A~F 六条路径到 4 结局（氧气逐检查点验算 §4）、氧气门三形态、
 *   DIVER/DECK/NPC 台词差分、尾声回响选播、存档 schema/summary；
 * - pendingChoice（V1 时序：旁白滑动缓存 → 选项句播完才生效，零插播）；
 * - sonarGate 仲裁（危机拍前置 / 空闲门 / 零重叠）、结算死窗（critical 首句）、
 *   搜索等待（单击=脉冲 / amb+余音替代合成等待声）；
 * - §4.4 三档提示（ping 8/18、continue 13/30、choice 25→short 台账降档）；
 *   §4.5 迷茫接管三级（L1 短句 → L2 缩小 → L3 替发脉冲）；
 *   §4.3 手势阶梯（首脉冲→上滑、首结局→菜单、教学句挂链尾）；
 *   §4.12 断点复述（F4 恢复首句锁）；
 * - §6.2 乱点机器人：无声操作 0 / 被动原句重复 0 / 打断失败 0 / 首操作 ≤10s /
 *   首成功 ≤20s；菜单（左右滑换项 + 单击确认 + 二次确认重开）。
 *
 * 运行：tools/node/bin/node web/abyss/test/playtest.mjs
