修复游戏图集事务与俄罗斯方块验收

为九个固定图集合同路径补齐持久事务、原子标记、锁守卫和崩溃恢复。统一校验主图与切片的资源、资产和任务身份，避免远端请求期间占用项目写锁。收紧俄罗斯方块静态语义、浏览器动作因果和固定场景合同，拒绝注释与伪 telemetry 绕过。迁移旧 Generic 俄罗斯方块根合同和试玩子任务合同，并失效旧场景回执。补齐事务故障、恶意脚本、真实 Chrome、game-chat 修复和合同迁移回归测试。同步 AI 游戏创作技术方案与共享决策记录。

 - 覆盖决策：game-chat fallback 只允许初始化缺失/占位入口的首次落盘。非占位 `game/index.html` 必须保留，并由当前 `code-prototype` 先读取和实际 patch，取得本人 `mutationRevision` 后才能运行 `game.static_smoke` 与交付；只读 smoke 不得冒充续作。确定性 fallback 只允许已实现真实语义的显式玩法模板：俄罗斯方块模板必须具备 10×20 棋盘、下落、移动、旋转、锁定、消行和触顶失败，收集模板只用于明确收集类目标，未知玩法失败关闭。纯继续目标未恢复时同样失败关闭。完成门新增 baseline 玩法连续性和 action-driven state 检查，generic Canvas 非空、三个按钮存在或静态 smoke 通过都不能单独证明任务没有换题。
 - 美术决策：`art-spec.png` 回归为规范图和下游派生 reference，不能铺作完整场景，也不能裁剪成玩家/目标。首版必须继续由 `art-asset-plan` 通过 icon-spritesheet 生成透明 `art-spritesheet.png`；桌面 Runtime 同时下载服务端 `iconImageSrcs`，按当前图集 resourceId 写入本地切片清单。game-chat 在任何本地落盘前要求稳定、非空的图集 resourceId，并在正式图集登记前要求切片严格等于四、每片 `sourceResourceId` 精确绑定整图，全部切片累计下载最多 `32 MiB`；四类差异按尺寸加规范 RGBA 像素摘要判定，PNG 编码字节不同不代表视觉内容不同。主图、四张 canonical 切片与切片清单作为一个提交合同，并把主图/切片摘要及 Canvas 身份冻结到 `.agent/runtime/art-spritesheet-contract.json` 私有回执；主图安装、回执或资产登记失败时必须恢复整组旧合同。generation 账本恢复允许对摘要一致的已落盘主图幂等补齐合同，摘要冲突不得覆盖。完成门重新读取切片时继续有界解码，并要求实际素材、公开清单、当前 Canvas 登记与私有回执在内容摘要、规范像素摘要、可见 alpha、四类唯一性和资源身份上全部一致。`code-prototype` 在活动 Canvas 中分别绘制玩家、方块/目标、障碍/场景和反馈四类不同切片。纯代码核心画面、猜测 atlas 等分坐标、单个裁切冒充全部类别、整图展示与路径诱饵失败关闭；编辑器仍允许仅有 `sliceWarning` 的完整透明图集完成，但 game-chat 必须等到真实切片可用。
+- 图集身份与恢复补充：canonical game-chat 图集是 External 通用资源模型的严格完成子集。主图与四个切片都必须含非空 `assetObjectId`，五个 ID 互不复用；同一对象在顶层、resource 与 asset 中重复出现的 `assetObjectId` 和 `taskId` 都必须逐项完全一致，冲突时不得择一冻结。公开切片清单和私有回执同时冻结 `sourceResourceId / sourceAssetObjectId / sourceTaskId / sourceCanvasProjectId / sourceReferenceResourceIds`，四项切片按 usage 唯一且逐项比较 `name / path / width / height / resourceId / assetObjectId / contentSha256 / pixelSha256`。旧项目仅缺私有回执时不得从可编辑公开清单伪造回执；只有同一 `project-supervisor-game-chat` 父 run 下处于 running 的 `art-asset-plan` scheduled child、固定输出路径且当前合同确实失效时，才允许 `replaceExisting=true` 原位 repair。任何 canonical 文件变化前，Runtime 必须在 `.agent/runtime` 私有事务目录原子持久化九个固定合同路径的旧状态并回读，随后写 `prepared` marker；主图字节先写 staging，再安装 canonical 主图，随后才提交四切片、公开清单、私有回执和 Canvas 登记，登记成功后写 `committed` marker 才可回收快照和 backup。恢复只在取得同一项目写锁后按持久 transaction id 扫描；`prepared` 未 `committed` 必须整组恢复旧合同，`committed` 只做幂等清理，不能凭随机 previous/replacement 文件名干扰正在提交的事务。这样即使进程被强杀且远端暂不可用，也能恢复完整旧合同，不留下“旧主图 + 新切片”或半写 canonical PNG。
+- Tetris 连续性补充：明确俄罗斯方块任务固定分类为 `tetris-v1`，不再回退 generic 可选遥测。静态门移除字符串、注释和 `if(false)` / 明显恒假分支诱饵，并要求可达 `fall -> lock -> clear` 调用链，拒绝自赋值旋转、虚假坐标推进、board 自赋值和空 splice。浏览器状态固定含 `activePieceId / rotation / row / lockedPieces / lineClearChecks / clearedLines / occupiedCells`，同时允许 `score / nextPieceId` 等不影响固定合同的扩展 telemetry；受控试玩必须证明同一活动方块同步旋转、重力下落或真实锁定、锁定后 activePieceId 更换、occupiedCells/clearedLines 与四格落盘或消行一致、消行检查执行，以及 restart 后棋盘与计数归零。旧合同或纯继续 successor 在真实读取恢复路径按有效原任务重新分类、重算指纹并回读迁移结果，不能保留 generic 逃逸路径。

 - game-chat 快车道只能在 `game/index.html` 缺失或仍是初始化占位，且当前 child run 尚未写入正式入口时使用首次 fallback `file.write`。项目已存在非占位入口时，后续 `code-prototype` 必须先保留并读取既有玩法，做真实局部修改并取得本人 `mutationRevision`，之后才能运行 `game.static_smoke` 与交付；禁止为了满足首版时限重新生成整份默认小游戏，也禁止连续只读 smoke。占位 fallback 仅允许俄罗斯方块和明确收集类等已有真实语义模板，未知玩法失败关闭。纯继续意图未能恢复唯一原始目标时同样失败关闭，不输出以“继续”为标题的兜底产物。
 - `assets/art-spec.png` 的唯一语义是视觉规范与派生参考，不是运行时背景、角色、目标或图集。game-chat 的核心玩家、方块/目标、障碍/场景和反馈必须来自独立派生的透明 `assets/art-spritesheet.png` 及其服务端 `iconImageSrcs` 本地切片；Runtime 以 `sourceResourceId` 把切片清单绑定到当前图集，并要求活动 Canvas 分别绘制四类不同切片。纯代码核心实体、猜测图集等分坐标、单个裁切冒充全部类别、整图展示、隐藏引用、微小水印和诱饵路径均不构成真实美术使用。`playable-web-game-state.v1.sequence` 只在真实输入、状态迁移或模拟状态变化时递增，不得由纯渲染帧推进。
+- game-chat canonical 图集进一步要求主图与四个切片都有非空且互不复用的 Canvas `assetObjectId`；同一对象在顶层、resource 与 asset 中重复返回的 `assetObjectId` 和 `taskId` 必须分别一致，冲突时失败关闭。公开 `assets/art-spritesheet-slices/manifest.json` 与私有 `.agent/runtime/art-spritesheet-contract.json` 必须同时绑定 `sourceResourceId / sourceAssetObjectId / sourceTaskId / sourceCanvasProjectId / sourceReferenceResourceIds`，并对四种 usage 的 `name / path / width / height / resourceId / assetObjectId / contentSha256 / pixelSha256` 做完整一致性比较。旧项目缺私有回执时不得从公开文件反向生成回执；只允许同一 game-chat root 下处于 running 的 scheduled `art-asset-plan` 对固定主图执行受限 `replaceExisting=true` repair，普通 pending、其它 Agent、其它路径或有效合同均拒绝。九个固定合同文件在任何 canonical 改动前必须快照到 `.agent/runtime` 私有事务目录并写 `prepared` marker，Canvas 资产登记成功并写 `committed` marker 后才可清理；恢复只在同一项目写锁内按 transaction id 整组回滚或幂等清理，远端下载阶段不得长期持锁，也不得在无锁 request 阶段修改 canonical 文件。
+- 图集本地提交以主图 staging 为线性化前置：任何新主图先写随机私有 staging 文件，替换时保留 previous，canonical 主图完整安装后才写四切片、公开清单、私有回执和项目资产登记。进程若在 backup/install 窗口退出，同一 accepted External generation 恢复先识别唯一同 suffix 的 previous/replacement 对并恢复旧主图，再按远端结果完成替换；若 canonical 已等于远端摘要，则不再要求替换授权，直接补齐其余合同。成功后清理主图、四切片、公开清单、私有回执和项目 manifest 的全部遗留 staging/backup。首次生成也禁止直接流式写 canonical 路径，避免部分 PNG 被误认为已安装结果。
+- 俄罗斯方块任务固定使用 `BrowserPlaytestScenario::TetrisV1`。`playable-web-game-state.v1.gameplay` 必须持续提供 `kind=tetris`、`activePieceId`、`rotation`、`row`、`lockedPieces`、`lineClearChecks`、`clearedLines` 和 `occupiedCells`；任何采样点删除字段都立即失败，但允许 `score / nextPieceId` 等额外 telemetry。静态连续性检查忽略字符串、注释和 `if(false)` / 明显恒假分支诱饵，并绑定真实 `fall -> lock -> clear` 调用链。浏览器因果探针要求 primary-action 在同一传播中旋转同一活动方块，start 后观察重力下落或真实锁定；锁定必须更换 `activePieceId`、只增加一个 `lockedPieces`，并使 `occupiedCells / clearedLines` 与四格落盘或实际消行相符，随后观察 `lineClearChecks`；restart 后棋盘和全部计数归零。旧/续跑合同在真实场景读取恢复路径按有效原任务迁移到该场景、重算 fingerprint 并回读一致，不能继续沿用 generic-v1。
 - 泥点不足是确定性业务中断，不是瞬态 Provider 故障或未知副作用。钱包的 `泥点余额不足` 与 `可消费泥点不足：...` 两种领域文案统一映射为稳定原因 `mud-points-insufficient`，不得自动重试；即使 External Generation durable ledger 已存在，也必须落为 `failed`，不能误入 `needs-reconciliation`。game-chat 顶部状态、持久失败对话与 `【Supervisor 阶段记录】` 统一显示“泥点余额不足，本轮游戏生成已中断。请充值后发送“继续”，系统会从当前项目进度接着完成。”，并禁止透传 operationId、URL、路径、密钥或任意上游正文。
