 When a stage tool, command, or verification fails, retry at most three times before treating that stage as failed. Keep the retries serial and scoped to the same stage and the same input: a retry must not open a parallel path, skip ahead to a later stage, or substitute a placeholder for the missing output.
 
+Every repairable failure must be fed back to the current LLM as the next debugging context before the stage is considered failed. Preserve the redacted tool or command error, the stage, the attempted input, and the evidence already collected; ask the LLM to inspect the current project, make the smallest real repair, and rerun the failed stage. A client-side `isError` tool result or a failed verification is feedback for the LLM, not by itself a terminal user-facing result. Do not silently swallow the error, replace it with a placeholder, or stop after the first failed attempt. Authentication, permission, billing, project identity, corrupted history, transport loss, cancellation, and uncertain paid-operation state remain terminal safety boundaries.
+
 Only after the third attempt also fails, stop and tell the user the failure reason — which stage failed, which tool or command reported the error, what the error says, and what is still missing. A stage whose three attempts never succeeded is not complete, and its missing output cannot be reported as delivered.

 - 平台主题事实源固定为 `packages/shared/src/theme.css`。画布通用 chrome 固定落在 `@genarrative/image-canvas-react`，主站与 Tauri 必须直接 import 同一组件和作用域样式；客户端不得复制 `src/components/image-editor/`，也不得导入主站完整 `src/index.css`。
 - 第一批共享 chrome 固定覆盖画布动作按钮、工具栏、工具分组和分隔符。按钮的默认、悬停、键盘焦点、选中、禁用和主次色语义由共享层表达；宿主只提供图标、文案、事件与业务禁用条件。

+
+## 修改顺序
+
+1. 在 `agent/direct_runtime/mod.rs` 保留三维/引擎意图与工程归属识别（含伪 3D、2.5D、代码话题例外）。
+2. 用"三维请求自选技术栈"合同替换澄清合同、工具阻断、注册门禁与首页创建阻断代码路径。
+3. 在三处装配点前置注入合同：首页回合、项目回合与测试用的旧装配点。
+4. 把工程合同里的 Phaser 固定约束按二维/三维分层。
+5. 更新定向用例与文档，运行格式化、编码检查与 diff 检查。

+## 修改边界
+
+- 允许修改：`apps/ai-game-creator-shell/src-tauri/src/platform_session.rs`、`commands.rs`、`runner/`（attach 参数与安装路径）、`project/external_editor_bindings.rs`、`project/resource_editor.rs`、`agent/generation/canvas_generation.rs`、`agent/direct_tools_mcp.rs`、`agent/direct_runtime/`、`assets.rs` 中与身份判据相关的调用点。
+- 允许修改：`apps/ai-game-creator-shell/src/services/platformSession.ts`、`clientAuth.ts`、`clientApi.ts`、`src/App.tsx` 及对应测试。
+- 允许修改：`src/services/apiClient.ts` 刷新收敛重试与对应测试。
+- 允许修改：`server-rs/crates/api-server/src/refresh_session.rs`、`auth_session.rs` 与对应测试。
+- 明确不修改：`/api/external/v1` 路由与 OpenAPI、`refresh_session` schema / 迁移 / 绑定、生成账本与计费、Provider 与 MCP 工具边界。
+
+## 实现顺序
+
+1. 原生会话状态拆分：`PlatformSessionSnapshot` 增加身份代次，`generation` 更名并明确为写入 revision；安装 / 清除 / 冻结校验按新判据重写，补单元用例。
+2. 逐个修正原生调用点（binding、生成 operation、MCP 会话、diagnostics、Runner attach），由编译器定位所有旧判据读取点。
+3. renderer：身份代次与 native revision 分离，续期走凭据更新路径；刷新失败只在权威失效时清会话；补前端用例。
+4. 刷新收敛：AGC 与网站前端在刷新 401 时用当前 cookie 重试一次。
+5. `api-server`：轮换失败不再下发清 cookie 响应，补定向用例。
+6. 回写主规范与共享记忆，删除临时计划。
+
+## 验证命令
+
+1. `npm run ai-game-creator-shell:check:rust`（或定向 `cargo test --manifest-path apps/ai-game-creator-shell/src-tauri/Cargo.toml platform_session`）
+2. `npm --prefix apps/ai-game-creator-shell test -- src` 对应前端定向用例
+3. `npm run test -- src/services/apiClient.test.ts`
+4. `cargo test -p api-server refresh_session --manifest-path server-rs/Cargo.toml`
+5. `npm run typecheck`、`npm run check:encoding`、`git diff --check`
+
+## 风险与回滚点
+
+- 风险：身份代次判据改宽后，若换号路径仍复用旧代次，旧账号请求可能带着新账号 token 发出。缓解：换号、退出和 origin 变化必须先推进身份代次；Rust 侧对同代次不同主体的写入失败关闭，并用用例覆盖。
+- 风险：revision 与身份代次混用会让迟到写入复活旧会话。缓解：写入顺序只认 revision，身份只认身份代次，两者分别有用例。
+- 回滚点：先回滚 renderer 的续期路径与原生判据（第 1-3 步），再回滚服务端响应语义（第 5 步）；`refresh_session` schema 不在本次改动内，无需数据回滚。
+
+## 执行结果
+
+1. `platform_session.rs`：`PlatformSessionSnapshot` 拆成 `identity_generation` + `revision`，新增 `PlatformSessionIdentity`、身份租约与 `validate_frozen_platform_session`；安装 / 清除按"revision 排序 + 身份归属"双判据实现。
+2. 原生调用点：`external_editor_bindings.rs`、`resource_editor.rs`、`canvas_generation.rs`、`direct_tools_mcp.rs`、`direct_runtime`、`assets.rs`、`commands.rs` 全部改按身份判定；`commands.rs` 的 IPC 改为 `install_platform_account_session(userId, accessToken, apiBaseUrl, identityGeneration, revision)`、`clear_platform_account_session(identityGeneration, revision)`、`read_platform_account_session_state()`。
+3. Runner：attach 参数新增 `platform_auth_revision`，`platform_auth_generation` 只表达身份代次；`remember_*` / `validate_*` 按 revision 排序、按身份归属判定。
+4. renderer：`platformSession.ts` 拆分 `platformNativeIdentityGeneration` 与 `platformNativeRevision`，续期走 `commitPlatformCredentialRefresh`（不推进身份代次）；刷新失败结果新增 `authoritative`，`AuthenticatedClient` 只在权威失效时登出。
+5. 刷新收敛：AGC `clientAuth.refreshClientAuthAccessToken` 与网站 `apiClient.refreshAccessToken` 在 401 后用当前 cookie 再试一次；网站侧额外要求本代次仍是当前代次。
+6. `api-server`：`refresh_session` 失败不再下发清 cookie 响应（`map_refresh_error_with_clear_cookie` 删除），并更新两条 `app::tests` 断言。

+## 目标
+
+用户要求做三维（3D）游戏时，DirectProject 不再把 Phaser 4.2.1 当作固定约束：由 Codex 自行选择三维技术栈并直接推进，客户端不要求先澄清引擎、不阻断工具、不拒绝登记产出。
+
+## 边界
+
+- 只读用户原文做确定性识别，不改写用户消息，不启动 Supervisor、专业 Agent、harness 或额外生成工作流。
+- 只对"说了三维、没有点名引擎"的回合注入自选栈合同；用户点名引擎时沿用既有工程合同（Cocos / Unity / Godot 等与当前目录不匹配时先说明不匹配）。
+- 用户明确选择"等轴 / 伪 3D / 2.5D"表现，或话题是代码里的三维概念时，不注入该合同。
+- 唯一保留的红线是诚实边界：不得用等轴伪 3D 或二维图集冒充三维交付而不说明。
+- 首页只加一行三维提示，不阻止创建项目；不改 `/api/external/v1` 契约、OpenAPI、DTO、SpacetimeDB schema 与前端投影协议。
+
+## 验收标准
+
+1. 常驻系统提示包含"三维请求合同"：三维请求不受 Phaser 固定约束，由 Codex 自选三维技术栈，可新增 npm 依赖，仍需说明选型。
+2. 命中三维请求时，系统提示前置一段自选栈合同（含当前工程识别结果），不被 16K 提示词上限截断。
+3. 点名引擎、主动选择伪 3D / 等轴 / 2.5D、代码话题（如"三维数组"、"value4"）不触发该合同。
+4. 引擎固定约束文案已按二维/三维分层：二维游戏仍固定 Phaser 4.2.1，三维请求不受该约束。
+5. 定向 Rust 用例覆盖识别、合同文本、工程识别与首页提示；格式化、编码检查与 `git diff --check` 通过。
+
+## 依赖
+

+
+## 目标
+
+同一账号在长回合内发生 access token 续期时，在途的生成、编辑、上传、确认和下载 operation 必须继续可用；只有登录主体、服务 origin 或登出状态真正变化时才允许中止它们。刷新失败与并发刷新不得把仍然有效的会话判成未登录。
+
+## 范围
+
+- AGC renderer 的平台会话状态机：身份代次与 native 写入 revision 的分离，续期不再推进身份代次。
+- 原生 Rust `platform_session` 会话状态：身份判据、token 判据、写入顺序判据的分离。
+- 冻结平台会话的校验语义（外部编辑器 binding、生成 operation、MCP 工具会话）。
+- 独立 Runner 的平台会话安装 / 清除与 attach 参数。
+- AGC 与网站前端的刷新失败语义、并发刷新收敛重试。
+- `api-server` `/api/auth/refresh` 轮换失败时的响应语义。
+
+## 不在范围内
+
+- 不改 `refresh_session` 的持久化 schema，不引入服务端轮换宽限表。
+- 不改 `/api/external/v1` 路由、OpenAPI 或共享 DTO。
+- 不改生成、计费、账本幂等键与恢复语义本身。
+- 不改 Provider、MCP 工具白名单、审批或项目锁。
+
+## 依赖与前置条件
+
+- 现有 native revision 与 durable GUI owner claim 语义保持不变。
+- 现有 `authentication-required` 错误分类保持不变，只收窄其触发条件。
+
+## 验收标准
+
+- [x] 同一账号续期后，续期前建立的在途冻结会话校验通过；换号、退出和 origin 变化后校验失败关闭。
+- [x] 同一账号续期不推进 renderer 身份代次，也不使 `AuthenticatedClient` / Direct 配置判据把会话判成 stale。
+- [x] 迟到或更旧的凭据写入被 revision 拒绝，不能覆盖更新的 token，也不能复活已清除的会话。
+- [x] 瞬时刷新失败（网络错误、5xx、网关错误、响应契约异常）不清除本地会话与 access token。
+- [x] 刷新返回 401 时先用当前 cookie 收敛重试一次；重试成功继续使用新凭据，重试仍 401 才清会话。
+- [x] `/api/auth/refresh` 轮换失败不下发清空 refresh cookie 的响应。
+
+## 证据要求
+
+- 自动化：AGC Rust 定向用例（身份判据、revision CAS、冻结会话）、AGC 前端用例（代次与刷新失败语义）、`api-server` 定向用例（轮换失败响应）、网站 `apiClient` 用例（收敛重试）。
+- 运行时：AGC shell Rust 定向测试与前端测试；`api-server` 定向 `cargo test`。
+- 边界：换号 / 退出失败关闭、迟到写入拒绝、并发刷新竞争、token 不出现在错误文本与持久化中。
+
+## 证据与未验证项

+
+- External v1 抠图和 AGC `agc_remove_background` 支持 `complex`（语义分割识别前景）与 `flat`（纯色背景抠图）；明确纯色背景优先 flat，模式缺省仍为 complex，主站前端保持现有行为。
+- flat 的颜色允许 `auto`、`#RRGGBB` 或省略，自动识别完全由 BgFilter 负责。主站只校验、透传，不调用视觉模型选色；complex 携带颜色、非法值和空字符串在入队前拒绝。
+- 来源、名称、模式与颜色共同区分客户端请求意图；旧参数调用及旧 External 请求的幂等指纹须保持稳定。

+
+## 2026-09-16 策划 Agent 工具执行退出项目级写锁并自动接续中断批次
+
+- 背景：策划 Agent 每个 `read_file` / `write_file` / `patch_file` 工具都在执行前竞争全局项目写锁，但同一会话已由 `.agent/design-agent/active.lock` 串行化，工具目标又限定在 `design_artifacts`；项目锁既不覆盖「工具 + 会话 checkpoint」事务，还把进程中断时的 `executing=true` 不确定窗口扩大到等锁与工具执行全程。真机项目出现 `pendingBatch.executing=true`、`function_call` 无配对 output、UI 只显示工作中且无错误的状态。
+- 决策：单次策划工具不再竞争项目级写锁，只保留策划命令锁与既有原子写入；GameAgent / DirectProject 的公共项目锁实现与调用不变。重开项目 hydrate 时，若命令锁可获取且当前批次处于 `executing=true`、当前 call 无 output，则自动续跑原回合：为该 call 补写「执行结果未保存」的工具错误、跳过剩余调用并交回 Provider 自愈；不得重放文件副作用，也不要求用户手动重试。
+- 验证：新增定向用例证明中断批次自动补齐工具 output、收到后续 assistant 回复、清空 pendingBatch 并结束原 turn，同时目标文件保持未修改（未重放 `patch_file`）；策划 Runtime 定向 14 条、策划工具 3 条通过，`cargo fmt --check`、`npm run check:encoding`、`git diff --check` 通过。

+## 2026-09-16 AGC 同 AppData 多窗口共享 Agent Runner
+
+- 背景：双击或再次启动 AGC 客户端时报「应用启动失败」，启动日志为 `startup.runner.owner-lock.failed details=AI 游戏创作界面已由同一 AppData 目录中的其他进程运行`。原设计（2026-07-27 / 2026-08-23）要求同一 AppData 只有一个 GUI owner，第二个界面进程在 setup 阶段就失败退出。
+- 决策（锁语义）：`agent-runner.gui-owner.lock` 改为**界面参与锁** `agent-runner.gui-participant.lock`，以共享句柄打开，同一 AppData 的任意数量窗口可同时持有；Runner 的启动检查、attach 门禁与 watchdog 只用“能否独占取得该文件”判断是否仍有窗口存活。全部窗口退出后才关停 Runner 并清理 endpoint。
+- 决策（claim 采纳与发布）：窗口启动先**采纳**durable claim（同一 epoch/revision），只有 claim 缺失或不可读才发布新 claim；登录、refresh、退出或换号才发布新 claim（新 epoch + 本窗口 revision），成为新的登录态权威。同一 claim 的重复 attach 是幂等空操作，不再清空 Runner 登录态；只有 epoch 变化或携带明确登出参数才允许替换 / 清空。并发发布以最后一次成功写入的 claim 为准，落败窗口按最新 claim 有界重试。
+- 决策（事件与退出）：manifest 失效与 Runtime update relay 的接收端从单槽改为按 `event_sink_token` 去重的注册表并广播，发送失败只淘汰该接收端；GUI 退出先释放本窗口参与锁，仍有其它窗口时保留 Runner（`agent.runner.gui_exit.retained_for_other_windows`），最后一个窗口才请求关闭。Runner 启动失败时先按最新 endpoint 复用一次，避免两个窗口同时冷启动时的实例锁竞争被误报成启动失败。
+- 边界：本机 GUI ↔ Runner 协议方法与参数不变，不引入多 Runner、不做跨 AppData 会话共享；项目级 `.agent/project.lock` 不变，多窗口仍不能并行写同一项目；平台登录态 generation 单调与 claim 失配失败关闭语义保持不变；混用新旧版本二进制访问同一 AppData 不属于支持场景。
+- 验证：定向 Rust `runner::tests::gui_owner_*` 11 条与新增的参与锁多窗口 / 存活判定 / claim 采纳与轮换 / 同 claim 第二个窗口不清空登录态用例全部通过；真实 debug 二进制 Windows smoke 证明同一 AppData 两个 GUI 都完成 `startup.setup.complete`、只存在一个 `--agent-runner` 进程、关闭一个窗口后另一个窗口与 Runner 继续存活、最后一个窗口退出后 Runner 退出并删除 endpoint；`npm run check:encoding`、`npm run check:doc-index`、`git diff --check` 通过。
+- 未验证 / 已知环境问题：真实安装包双开需要重新构建发布后才能验证；`durable_provider_handoff_prevents_shutdown_even_when_corrupt`、`durable_provider_retry_prevents_shutdown_and_reopens_writes`、`runtime_interrupt_for_true_steer_decision_only_interrupts_older_provider_cursor` 三条用例在本机改动前的基线上即失败（Windows 安全对象 owner 校验与 Provider 请求重复），与本决策无关。

+## 2026-09-16 DirectProject 三维请求解除 Phaser 固定约束，由 Codex 自选技术栈
+
+- 背景：三维需求（"做个 3D 城市游戏"）在只有 Phaser 4 二维通道的工程里没有落点，而完成判定以"源码引用已登记平台图片 + 浏览器渲染到该图"为硬门禁，模型可推进的唯一动作退化成生成图集；真机侧表现为长时间生图与反复接线，等轴伪 3D 成了默认交付。产品决定不再用"先澄清引擎"卡住三维请求，改为放开选型。
+- 决策：用户消息表达三维（3D / 三维）且没有点名引擎时，本回合注入**自选技术栈合同**：不受"新 Web 游戏固定 Phaser 4.2.1"约束，由 Codex 自行选择三维技术栈（Three.js、Babylon.js 等 npm 运行时，或当前工程自带的引擎），可以按需新增 npm 依赖、调整工程结构，并在回复里说明选型；客户端不要求先澄清、不阻断任何工具、不拒绝登记产出。
+- 决策（常驻口径）：`DIRECT_AGC_ENGINEERING_GUIDANCE` 的 Phaser 固定约束按二维/三维分层——二维游戏仍是 Phaser 4.2.1，三维请求不受该约束。首页回合只加一行三维提示，仍允许按既有规则创建项目。
+- 边界：用户点名引擎时沿用既有工程合同（Cocos / Unity / Godot 等与当前目录不匹配时先说明不匹配）；用户主动选择"等轴 / 伪 3D / 2.5D"或话题是代码里的三维概念时不注入合同。唯一保留的红线是不得用等轴伪 3D 或二维图集冒充三维交付而不说明。识别只读用户原文，不改写消息、不触发额外工作流，也不做工具阻断或注册门禁。
+- 影响范围：`apps/ai-game-creator-shell/src-tauri/src/agent/direct_runtime/mod.rs`。**未改** `/api/external/v1` 契约 / OpenAPI / DTO、SpacetimeDB schema、AGC 工具桥行为、前端投影与资源工作台。
+- 验证方式：`three_dimensional_game_request_frees_the_engine_choice`、`explicit_flat_presentation_requests_do_not_trigger_three_dimensional_selection`、`named_engine_requests_keep_the_existing_engineering_rule`、`three_dimensional_contract_reports_the_current_project_engine`、`home_three_dimensional_note_keeps_project_creation_available`、`system_prompt_is_bounded_and_declares_direct_runtime`，以及 `agent::direct_tools_mcp` 17 passed；`cargo fmt --check` 通过。本机临时目录 owner ACL 与进程用户不一致，涉及 `init_local_game_project_at` 的既有用例（含未改动模块）在本机无法执行，全量分片与真机 smoke 未在本轮取得。

+## 2026-09-16 图标图集自动拆图上限提高到 256
+
+- 背景：AGC 图标图集自动连通域识别在一次生成中识别出 86 个区域，原有 64 片上限在后处理阶段阻断了请求；该上限同时影响 api-server 自动 / 手动切片、SpacetimeDB 批量落库和统一生成结果 item 数量。
+- 决策：将可输出独立切片上限统一提高到 `256`；统一生成结果最多 `258` 个 item（256 个切片加 provider 原图和透明整图）。保持原始连通域 `4096`、总裁剪像素、CPU / 内存 admission、并发上传和处理时限不变。
+- 边界：超过 256 仍按现有 `output-slice-limit-exceeded` / `sliceWarning` 语义失败关闭切片写入；自动路径保留可信整图，手动路径继续在持久化前返回错误。
+- 验证：平台切片器、api-server 警告映射与 payload、SpacetimeDB 结果 / 批次校验均覆盖 256 成功边界和 257 溢出边界。

+## 2026-09-16 平台会话身份与凭据分离

+- 背景：长回合保活和 401 续期每次签发新 access token，并推进 native generation 重新安装原生会话；冻结平台会话同时比对身份与 token 字节，于是同账号的正常续期被等价成换号，并发在途的生成 / 编辑 / 上传 / 确认 / 下载 operation 全部被判为“旧账号请求”失败。更彻底的一层是原生会话、Runner attach 与 renderer 代次都把“写入顺序”和“身份归属”压在同一个计数器上。
+- 决策：平台会话拆成身份（`userId + api origin + identity generation`）与凭据（当前 access token）。identity generation 只在登录、切号、登出或新的 GUI authority epoch 推进；同账号续期只更新凭据并推进只用于拒绝迟到写入的 revision。冻结会话校验、MCP 会话身份与 Runner attach 统一按身份判定，换号 / 退出仍然失败关闭。刷新失败只在服务端明确 401/403 且一次收敛重试后仍失败时清会话；`/api/auth/refresh` 的轮换失败不再下发清空 refresh cookie 的响应。

+
+## 2026-09-16 CI 宿主 CPU 上限：Jenkins 16 核 / Gitea Actions runner 12 核
+
+- 背景：`genarrative-station`（32 逻辑核）上 Jenkins Built-In Node 与 Gitea Actions runner 共用同一宿主。Jenkins `jenkins.service` 原先没有任何 CPU 限制（`cpu.max=max`），构建期 Web / Api / Stdb 三分支并行（Vitest 8 线程 + 两次默认 32 job 的 cargo）把整机顶到 80%~95%；`gitea-runner` 容器 `--cpus=24`（75%）在 push 触发的 CI 波峰里实测峰值 24.8~25.3 核，是同一时间窗里更大的单一消耗方。
+- 决策：两路 CI 都设硬上限。Jenkins 侧 `systemctl set-property jenkins.service CPUQuota=1600%`（16 核 / 50%，覆盖 Built-In Node 上所有子构建，立即生效、无需重启，drop-in 落 `/etc/systemd/system.control/jenkins.service.d/50-CPUQuota.conf`）。runner 侧把 `/opt/gitea-stack/compose.yml` 的 `cpus` 由 `"24.0"` 改为 `"12.0"`（12 核 / 37.5%），并用 `docker update --cpus=12 gitea-runner` 让运行中的容器立即生效，不重建容器、不中断在跑 job。
+- 边界：Deploy 阶段在远端 dev / release agent 执行，不受该上限约束。调整只动这两处：`systemctl set-property / revert jenkins.service`、`docker update --cpus=<n> gitea-runner` 加同步 compose（备份 `/opt/gitea-stack/compose.yml.bak-<时间戳>`）。
+- 验证：限速后 `Genarrative-Full-Build-And-Deploy` #289 / #290 SUCCESS；采样期 Jenkins 峰值 10.2~10.5 核、限流不足 2s（可忽略），runner 峰值 12.07 核且持续出现 throttling，整机回落到 2.6%~19.8%。

 ## Gitea CI 依赖闭合
 
 `.gitea/workflows/project-ci.yml` 的客户端门禁拆成八个 job，每个 job 只预热自己会构建的那几份依赖：`AI game creator shell Rust shard 1/4` 到 `4/4` 各只预取 AGC 壳 manifest 并各跑一片（AGC 壳那份 `Cargo.lock` 的 path 依赖已含 `platform-llm`、`platform-agent`、`agent-runtime-core` 与 `shared-contracts`），`AI game creator shell Rust smoke` 同样只预取 AGC 壳 manifest（`agent-run` smoke 会用 `src-tauri/Cargo.toml` spawn `cargo run`），`AI game creator shell Rust crates` 预取 `server-rs/Cargo.toml` 与两个独立 crate，`Native shell tests` 预取桌面壳与 AGC 壳 manifest，`AI game creator shell web tests` 不触碰 Cargo，不预热。AGC 壳的 4 个分片 job、smoke job 与 crates job 只用 cargo 与 node 内建模块，因此不执行 `npm ci`。两个被 `server-rs/Cargo.toml` 排除、且没有提交 `Cargo.lock` 的独立 crate（`agent-runtime-core`、`agent-runtime-orchestration`）只能在 `AI game creator shell Rust crates` 里用不带锁标志的 fetch。AGC 壳的 bin target 单测（约 2466 条）由 `apps/ai-game-creator-shell/scripts/run-rust-shell-test-shards.mjs` 编译一次后按 `--list` 名单分 4 片：CI 的每个分片 job 用 `--shard-index=<i>` 只跑自己那片，片内保持 `--test-threads=1` 并各自使用独立 `TMPDIR`，片与片之间靠 job 级并发摊开；本地不传 `--shard-index` 时仍是同一条命令把 4 片放进程里并行。不要改回「一个 job 内多进程并行这几片」——同一容器里它们会争抢共享 `HOME`、target 目录与固定临时路径，实测比整套串行还慢。每个分片 job 都会自校验「片并集等于全集且互斥」，因此改分片规则不会静默漏跑。Backend host workspace tests 使用 `cargo test --locked --workspace --exclude spacetime-module --no-fail-fast`，避免 `spacetime-module` 的 `spacetime-types` feature 统一污染普通领域 crate 的 host 测试；随后单独执行 `cargo test --locked -p spacetime-module --no-fail-fast`，由 `spacetime-module/src/active.rs` 在 host 测试构建期间提供仅测试期的 SpacetimeDB ABI 链接支持，使该 crate 的纯单元测试也纳入 Backend 门禁。`spacetime-module` 的 reducer / procedure 运行时行为仍必须通过真实 SpacetimeDB runtime/integration harness 验证，host 链接支持不得被当作运行时替身。Backend 另外执行 `cargo check --locked -p spacetime-module` 验证模块源码。AGC 壳检查还会运行 `platform-llm` 与 `shared-contracts` 的 server-rs workspace 测试，这些命令以及 AGC 壳测试必须带 `--locked`，避免在测试阶段重新解析 registry index；锁文件发生变化时应先更新受信任 CI 镜像缓存，再重跑门禁。

 - 处理：用 `editor_generation_operation` 记录 durable receipt，分开 request fingerprint 与整笔 commit SHA-256。首次调用在同一 SpacetimeDB 事务中校验 lease 并写 object/resource/asset/binding/canvas/job/receipt；重放先查 receipt，再读回逐 slot 权威事实精确比较。receipt 缺失但 resource/asset/binding 已存在时失败关闭，不得补写 receipt；事务前已确认的 asset object 只能在 ID、bucket/key、owner、策略、媒体、来源和实体字段全部相等时复用。
 - 时间与并发：`completed_at_micros` 必须为正数，object/resource/asset/binding/canvas 候选原时间字段与它一起纳入 commit SHA-256，不能在每次重放时重新取时；job 终态和完成事件只用 SpacetimeDB `ctx.timestamp`。canvas CAS 冲突后只刷新 project 并重算布局，不重跑 Provider / OSS。OSS 尚未进入该事务，无引用 object 仍是需另行清理的边界，不要宣称跨 OSS exactly-once。

+- **现象**：`Genarrative-Stdb-Module-Publish` 在备份和 SpacetimeDB 就绪后，于 `spacetime publish` 报 `Permission denied`。
+- **原因**：Jenkins 以 root 运行时 `${HOME}/data/tmp` 位于 `/root` 下；即使发布临时子目录已 `chown` 给 `spacetimedb`，父目录仍不可遍历。
+- **处理**：发布给 `--run-as-user` 的 WASM 临时目录改用 `/var/tmp`，继续使用随机目录并在退出时清理。

+## Git hook 测试必须清除继承的 Git 仓库环境
+
+- 在 hook 内运行临时仓库测试时，`cwd` 不会覆盖继承的 `GIT_DIR`、`GIT_WORK_TREE` 或 `GIT_INDEX_FILE`。未隔离的 Git/lint-staged 子进程可能向真实仓库提交 fixture，甚至把测试版 ESLint、Prettier 配置带入主分支。
+- fixture 子进程统一清除 `GIT_*` 环境，并用一次性外层 linked worktree 验证引用、索引、配置不变；原有工程检查规则保持完整，不能用逐项关闭规则修复 fixture 污染。
+- 2026-09-16 复核：从链接工作树 `git push`/`git commit` 时，Git 注入 `GIT_DIR=<主仓库>/.git/worktrees/<name>`、`GIT_WORK_TREE`、`GIT_INDEX_FILE`，husky → npm → `check:repository-ci` → 夹具测试整链条继承。夹具 `git config user.name "Git Hooks Test"` 会写进共享 `.git/config`（此后所有提交 author 变成 `Git Hooks Test`）；夹具 `git init` 按是否带 `GIT_WORK_TREE` 分别写成 `core.bare=true`（`fatal: this operation must be run in a work tree`）或 `core.worktree=<临时夹具目录>`（`git status` 实际在操作临时目录）。
+- 处理：钩子与门禁入口先 `unset GIT_DIR GIT_WORK_TREE GIT_INDEX_FILE GIT_COMMON_DIR GIT_PREFIX GIT_CONFIG_PARAMETERS GIT_CEILING_DIRECTORIES`；夹具 Git 调用在命令前自检 `rev-parse --show-toplevel` 等于夹具目录，落到外部仓库立即失败；守卫用例的子进程必须真的继承 `GIT_DIR`，否则断言会空转。
+- 验证：`git config --show-origin --get user.name` 出现 `file:.git/config  Git Hooks Test`、`git rev-parse --show-toplevel` 指向 `%TEMP%\genarrative-pre-push-*\repo` 都是被污染的确定性证据；被 `core.worktree` 劫持期间执行的 `git pull` 会把检出写进临时目录，真实工作树整体落后（本次 93 个文件），配置修好后用 `git checkout HEAD -- .` 回填。
+- Vitest 的 `toHaveBeenCalledWith` 匹配任意一次调用，失败输出会列出其它命令；应先定位相同命令的真实参数差异，不能由其它调用的序号推断时序故障。
+- 存在后台轮询的 IPC mock 不应要求目标命令占据全局最后一次调用。验证刷新时先记录调用边界，再筛选该边界之后的目标命令，严格核对其最后一次参数，避免后台查询影响断言，也避免旧调用掩盖刷新未执行。

+## 2026-09-16 并发生图遇到“登录态冲突”：身份代次与凭据轮换混用
+
+- **现象**：DirectProject 长回合里并发派发的生图 / 素材生成请求中途报 `authentication-required: 陶泥儿登录态已变化，旧账号请求已停止，请使用当前账号重试`，或平台工具返回 `HTTP 401 invalid-token`；账号并没有切换，重新登录后短时间内可复现。
+- **原因**：客户端把两件事压成了一个判据。原生冻结会话（`PlatformSessionSnapshot`）同时承担“身份归属”和“access token 字节比对”，而长回合保活与 401 续期每次都会签发新 token 并推进 native generation 重新安装会话；于是同账号的正常续期被等价成换号，续期窗口内所有在途生成、编辑、上传、确认和下载 operation 全部失配。保活定时器（回合 busy 时每 5 分钟一次）会稳定落在生图窗口内，所以并发越多越必现。另一层在服务端：`/api/auth/refresh` 是严格一次性轮换，且失败时下发清空 refresh cookie 的响应；两个窗口 / 实例并发续期时，输的一方会把赢家刚写入的有效 cookie 删掉。
+- **处理（现行口径）**：平台会话统一拆成**身份**（`userId + api origin + identity generation`）与**凭据**（当前 access token）。identity generation 只在登录、切号、登出和新的 GUI authority epoch 推进；同账号续期只更新凭据并推进写入 revision（revision 只用于拒绝迟到写入）。冻结会话校验只比身份，比 token 字节的判据已被取代。刷新失败语义收紧为：只有服务端明确返回 401/403 且经一次收敛重试后仍失败，才清本地会话；网络错误、5xx、网关错误和响应契约异常必须保留会话与 access token。`/api/auth/refresh` 的轮换失败不再下发清 cookie 响应。
+- **验证**：AGC `platform_session::tests` 覆盖“同身份 token 轮换后冻结会话仍有效”“换号 / 退出后失效”“迟到 install 被 revision 拒绝”；`appSurface` 前端用例覆盖“续期不推进身份代次且 native 写入 revision 递增”“瞬时刷新失败不清会话”；网站 `src/services/apiClient.test.ts` 覆盖“刷新 401 后收敛重试成功”与“两次都被拒绝才判权威失效”；`api-server` `refresh_session_*` 覆盖“轮换失败不下发清 cookie”。定位同类问题先看冻结会话判据里有没有 token 字节，再看服务端失败响应有没有 `Max-Age=0`。

+## 2026-09-16 同步 Tauri 命令里 `tokio::spawn`：点「终止」整个客户端 abort 闪退
+
+- **现象**：AGC 客户端（陶泥儿 0.1.46 安装包，`C:\Users\<用户>\AppData\Local\陶泥儿\genarrative-ai-game-creator-shell.exe`）在对话回合运行中点输入盒的「终止」后整个 App 直接消失。Windows 事件日志 `Application Error` 1000：异常代码 `0xc0000409`、出错模块就是该 exe、偏移 `0x3395066`；`%LOCALAPPDATA%\CrashDumps` 留下同名 minidump，其 ExceptionStream 为 `NumberParameters=1`、`Param[0]=7`（`FAST_FAIL_FATAL_APP_EXIT`）⇒ Rust `abort()`，既不是栈溢出（`0xC00000FD`）也不是访问违例（`0xC0000005`）。
+- **原因**：`cancel_direct_codex_turn` 是**同步** Tauri 命令，Tauri 把非 `async` 命令直接跑在 IPC 回调线程（Windows 上是 WebView2 的 UI 线程）；该线程没有进入任何 tokio runtime 上下文（`main` 只 `tauri::async_runtime::set(handle)` 加泄漏 Runtime，从未在调用线程 `enter()`）。终止链路 `cancel_direct_codex_turn_at → CodexTurnStartCancellation::cancel → maybe_interrupt` 却用 `tokio::spawn` 派发 `turn/interrupt`：在没有上下文的线程上 `tokio::spawn` 经 `Handle::current()` panic（"there is no reactor running"），panic 又跨不过 Tauri 的 IPC 回调边界，Rust 只能 abort 整个进程。同一模块的 `CodexThreadLease::drop`、`CodexTurnGuard::drop` 是同一形态。引入点是 2026-09-15 23:37 的 `76bbeb684 重构 DirectProject Agent 深模块`；既有覆盖只有 `#[cfg(unix)]` 的 `#[tokio::test]` 走 Drop 守卫路径，碰不到同步命令线程，所以 CI 全绿。
+- **处理**：`codex_app_server/mod.rs` 新增 `spawn_codex_app_server_task`，统一经 `tauri::async_runtime::spawn` 派发（生产环境就是 `main` 装的深栈 runtime）；终止、租约 Drop、回合 Drop 三处一起改走它。判据是「调用点可能位于没有 tokio 上下文的线程」，不是「这个函数看起来像异步」。
+- **验证**：新增 `codex_app_server_task_dispatch_needs_no_tokio_runtime_context`——在 `std::thread::spawn` 出来的无上下文线程里调用派发入口，若回退成 `tokio::spawn` 即失败（实测回退后报 `there is no reactor running, must be called from the context of a Tokio 1.x runtime`）。
+- **排障注意**：Release GUI 没有 panic hook、也没有 stderr，panic 文案不会落盘；`diagnostics/application.log` 只会停在崩溃前最后一行（本次停在 `agent.codex_app_server.remote_control disabled` 之后），所以「应用日志没有异常」不能当作「没有 Rust panic」，要结合 WER 事件、minidump 的 fail-fast 参数与调用线程上下文判断。
+- **关联**：`apps/ai-game-creator-shell/src-tauri/src/agent/codex_app_server/mod.rs`、`apps/ai-game-creator-shell/src-tauri/src/main.rs`（`install_agent_runtime_async_runtime_with_deep_stack`）、`apps/ai-game-creator-shell/src-tauri/src/commands.rs`（`cancel_direct_codex_turn`）。
+
+## 2026-09-16 AGC 壳跑过 `cargo test` 后前端 typecheck 必红：ts-rs 导出把 `generated/*.ts` 重写成另一种形状
+
+- **现象**：在 `apps/ai-game-creator-shell/src-tauri` 跑过 `cargo test` 之后，`npm run ai-game-creator-shell:typecheck` 报 10 条类型错（`src/features/project-workspace/resourceReferences.ts:106-112` 的 `string | undefined` 不能赋给 `string | null`；同文件 134 行的对象字面量带 `type: 'message'`，而 `DirectCodexUserMessageItem` 里没有该字段），`npm run ai-game-creator-shell:build` 也死在 `beforeBuildCommand` 的同一条 typecheck 上。
+- **原因**：crate 里的 ts-rs 导出会按**本机依赖版本**重写 `src/features/project-workspace/generated/DirectCodexUser*.ts`：注释头变成 "This file was generated…"、字符串改双引号、`DirectCodexUserMessageItem` 丢掉 `type: 'message'` 判别字段、并多出一个 `DirectCodexUserMessageEnvelope.ts`。仓库里提交的那份是前端真正依赖的形状（前端按带 `type` 的判别联合写），重写后两边就对不上——错在生成器版本漂移，不在前端。
+- **处理（现行口径）**：不要把重写结果当改动提交。跑过 `cargo test` 或构建后先 `git checkout -- apps/ai-game-creator-shell/src/features/project-workspace/generated`，再删掉多出来的 `DirectCodexUserMessageEnvelope.ts`，然后才做 typecheck / 打包；绑定与前端形状冲突时以**已提交的绑定 + 前端**为基准排查。
+- **验证**：恢复提交版本后 `npm run ai-game-creator-shell:typecheck` exit 0（`[skill-pack] OK`）；保留重写结果时同一条命令 exit 2。release 构建本身还会在 `src/features/ui-editor/types/` 落下 `BindingChange.ts` / `BindingDTO.ts` 两个无人引用的未跟踪文件，属同类生成产物。
+- **关联**：`apps/ai-game-creator-shell/src-tauri/src/agent/direct_codex_user_item/`（ts-rs 导出源）、`apps/ai-game-creator-shell/src/features/project-workspace/resourceReferences.ts`、`apps/ai-game-creator-shell/scripts/build-release.mjs`（`beforeBuildCommand`）。

+# AGC 抠图模式与背景色透传方案
+
+## 目标
+
+主站编辑器保持现有前端行为（继续使用 `complex`），同时扩展 External v1 抠图接口和 AGC 客户端，使客户端可以选择 `complex` / `flat`，并把 `screenColor` 原样交给 BgFilter。`complex` 用语义分割识别前景，`flat` 用于纯色背景抠图；确定背景为纯色时优先使用 `flat`。`auto` 的背景色识别完全由下游服务负责，主站不读取图片、不调用模型决策颜色、不生成颜色兜底值。
+
+## 当前 BgFilter 契约
+
+已登录生产服务器核对 `/root/BGfilter`，当前代码版本为 `f1a0833`，运行进程为 `python -m uvicorn app:app --host 0.0.0.0 --port 6006 --workers 1 --no-access-log`。服务契约为 `POST /remove-background` multipart：
+
+- `background_mode`：可选，`flat` 或 `complex`；
+- `screen_color`：可选，支持 `#RRGGBB`、`auto` 或省略；省略/`auto` 时由 BgFilter 从图片边框自动检测；
+- `complex` 模式忽略 `screen_color`；
+- 自动检测失败由 BgFilter 返回 400。
+- 若配置 `BGFILTER_AUTH_TOKEN`，必须发送 `X-Genarrative-Image-Token`；缺失或错误返回 401；未配置时该接口不在服务层做 token 校验。
+
+主站向 BgFilter 发送 `#RRGGBB` 时保留 `#`，`auto` 也原样发送，不做所谓的“hex 转换”。
+
+服务器行为：`screen_color` 在 `auto` 或省略时由服务自动检测；`#RRGGBB` 用作指定背景色。`background_mode` 缺省在 BgFilter 侧为 `flat`，因此主站必须为 External v1 旧请求显式归一化为 `complex`，不能把下游服务的默认值直接当成主站默认值。
+
+## External v1 请求契约
+
+接口保持：
+
+```text
+POST /api/external/v1/editor/images/background-removals
+```
+
+新增可选字段：
+
+| 字段 | 取值 | 缺省/行为 |
+| --- | --- | --- |
+| `backgroundMode` | `complex`、`flat` | 不填按 `complex`，保证旧客户端兼容 |
+| `screenColor` | `auto` 或 `#RRGGBB` | 不填则不向 BgFilter 发送该字段 |
+
+组合规则：
+
+1. 不传新增字段：按 `complex` 执行。
+2. `complex` 不允许传 `screenColor`，返回 400。
+3. `flat` 可以传具体 `#RRGGBB`、`auto`，也可以省略颜色。
+4. 模式和颜色严格按原值校验；非法值、空字符串、前后空格和大写 `AUTO` / `FLAT` 返回 400。十六进制颜色的字母允许大小写。
+5. 主站只做格式和组合校验；`auto` 不在主站解析，直接转发给 BgFilter。
+6. HTTP 请求中的 `null` 视同省略；模式省略时提供非 null 颜色同样违反 complex 约束。客户端 MCP 可选参数应省略，不传 null。
+
+格式或组合错误在入队前返回 400；BgFilter 自动检测失败发生在异步执行阶段，任务通过既有失败状态收口，不把已接受的 202 改成同步 400，不启动其他抠图方式兜底。
+
+OpenAPI 与客户端工具的对外说明只描述模式用途、参数约束和调用方可见的结果；provider 选择与兜底策略保留在内部技术方案中，不写入对外 description。
+
+主站前端继续不传新增字段，因此用户行为不变。
+
+## AGC 客户端改动
+
+`agc_remove_background` 增加可选参数：
+
+```json
+{
+  "sourceLocalAssetId": "...",
+  "assetName": "...",
+  "backgroundMode": "flat",
+  "screenColor": "auto"
+}
+```
+
+客户端保留旧参数调用；新字段不填时不改变旧调用语义。客户端不读取图片、不自动选色、不把 `auto` 改写为具体颜色，使用原有 Bearer 认证、幂等键和队列返回模型。
+
+工具 schema、桥接参数校验和随包 `agc-client-projection` Skill/契约说明必须保持一致。模式与颜色属于请求意图，必须参与客户端幂等指纹；同一图片与名称的不同模式不能复用同一次请求。缺省 complex 且没有颜色时保留既有指纹。主站在默认值归一化之前计算 External 请求指纹，缺失的新字段不序列化，避免旧请求重放发生冲突。
+
+## 实施任务
+
+### 任务一：冻结 BgFilter 契约
+
+记录服务器已支持的模式、颜色格式、自动检测和错误行为。不得把 SSH 地址、服务器凭据写入客户端或公开契约。
+
+### 任务二：更新主站 DTO 与 OpenAPI
+
+为 External v1 和内部任务 DTO 增加可选字段，更新 `docs/openapi/genarrative-external-v1.openapi.json`，写明默认值、组合约束和 400 响应。
+
+### 任务三：更新主站归一化与队列
+
+缺省模式归一化为 `complex`；`complex + screenColor` 拒绝；`flat` 允许颜色、省略或 `auto`。队列保存字段，worker 始终发送 `background_mode`，仅在调用方提供颜色时发送 `screen_color`，值原样透传。
+
+### 任务四：更新 AGC 客户端
+
+增加参数 schema、请求体字段和本地校验，更新 Skill、projection contract 与测试。旧客户端请求必须继续有效。
+
+### 任务五：联调与验收
+
+覆盖旧请求、`flat + auto`、`flat + #RRGGBB`、`flat` 不传颜色、`complex`、`complex + screenColor` 和非法值；使用真实 BgFilter 验证 multipart 字段及自动检测错误传播。

+- 主站 `cargo test -p api-server background_removal`：36 项通过，覆盖非法请求入队前拒绝、缺省 complex、队列参数保留、旧请求指纹、父侧内部 RPC 和 provider multipart。
+- `cargo test -p api-server bgfilter`：52 项通过，包括 flat 的 auto/省略/具体颜色以及既有生成链路。
+- `exported_openapi_json_contains_external_editor_routes_and_security` 契约测试通过。
+- 客户端 `agent::direct_tools_mcp::tests` 18 项、`agent::skill_pack::tests` 4 项与抠图幂等指纹测试通过；Skill manifest 内容指纹已同步。主站与客户端 rustfmt、文档索引、编码及 diff 检查通过。
+- 真实 BgFilter（版本 `f1a0833`）：使用进程内凭据串行请求 `flat + auto`、flat 省略颜色、`flat + #CFEFFF`、complex；四组均返回 200、512×512 RGBA PNG，alpha 范围均为 0–255。
+- 无纯色背景的随机噪声图片使用 flat + auto 返回 400，确认自动识别失败要求调用方提供颜色。测试没有修改服务器代码或配置。
+- 本地 `npm run dev:api-server` 已尝试，但当前配置指向的 SpacetimeDB 不可连接，服务停留在启动恢复重试，`/healthz` 未通过；已结束本次启动。完整登录客户端 → 主站持久化队列 → 结果回写的运行时验收尚未完成，不能用真实 BgFilter 的独立测试代替。没有部署本次主站或客户端代码。

+## 资源卡选中工具栏与导出
+
+- 共享选中工具栏按实际显示的快速编辑、编辑动作、改造、导出与宿主动作组生成分隔线；空组不产生分隔线，不依赖宿主 CSS 隐藏重复线。
+- AGC 所有具有本地文件路径的素材都显示带文字的「导出」按钮，位于工具栏末组的「删除素材」之前，两者之间不插入分隔线；「重命名」继续保留在前面的常规动作组。工具栏宽度上限为 `min(92vw, 800px)`，窄屏仍可横向滚动。图片、视频、音频、动画、UI、文档及其它文件共用 `isResourceCanvasExportable`，不按媒体类型限制导出；无文件路径及虚拟项目版本不提供文件导出入口。
+- 导出继续复用 `saveProjectResourcesToDisk`：原生保存对话框选择路径，`save_local_project_asset_file` 复制原始文件字节，不转图片、不重编码、不另建 IPC。后端继续校验源文件、敏感路径和目标路径；取消不写文件，失败通过工作台提示。
+
+## 文档与代码素材预览
+
+- 文档与代码素材选中工具栏提供「预览」，打开独立、可滚动的只读弹窗；关闭、切换素材或项目后不残留旧内容。加载中、空文件与读取失败分别呈现，允许重试可重试的错误。
+- 复用资源预览队列、身份缓存、项目 scope、失效与权限校验，继续调用 `read_local_project_text_preview`。代码卡不做可见性预取，仅用户显式打开详情时读取；不新增 IPC，不扩大可读取文件范围，不增加编辑/保存能力。
+- 文档正文统一使用现有 Markdown 渲染器；代码文件以按扩展名标注语言的 Markdown 围栏代码块呈现。围栏必须长于正文内的反引号串，正文空行与缩进保持原样，不把源码当 Markdown 正文或 HTML 执行。
+- 现有 Markdown 渲染器统一提供代码高亮，保留 HTML 禁用及外链/图片安全策略；未知语言回退普通代码块。超大正文跳过高亮但不截断内容，避免流式对话或文件预览被高亮计算阻塞。

+## DirectProject 用户消息契约验证
+
+`chat_with_game_creator_direct_codex` 必须携带 `projectPath`、`prompt`、稳定的 `clientTurnId` 和完整 `userItem`；`creationType` 与 `attachments` 按实际输入传递。Rust 通过 `projectPath` 解析项目身份，不接收额外 `projectId`。界面测试必须核对 `userItem` 的消息身份、角色、正文及附件内容，拒绝回合用例仍验证实际返回的错误原因。重开项目的历史恢复测试使用 `read_direct_project_history_slice` 的 canonical raw items 与 `hasMore`，首屏 `limit: 20`。资源图和生成任务的读取继续遵守原有工作台恢复逻辑，不因聊天断言失败延迟、关闭或改变它们。
+
+## 2026-09-16 DirectProject 回合展示唯一归属
+
+- 交付合同：实时消息、历史回读、工具详情与最终回复先归一为按 `clientTurnId` 唯一的回合，再渲染一次。用户消息始终保留；同一回合的正文、工具和耗时不能从消息、实时尾部、未归属尾部等多个出口重复展示。
+- 归属来自 `direct-codex:{clientTurnId}:{role}`、文本流中保留的原始 item ID，以及项目历史内明确用户记录之后的 assistant 记录。先在已加载的完整消息集合中关联，再做可见分页；持久历史继续通过 canonical item 切片懒加载，`hasMore` 为真时，未加载回合的工具流不得漂到当前页尾部。禁止将第 N 个有工具回合配给第 N 条用户消息，禁止按文本长度、标点或时间窗猜测归属。缺身份的旧记录保留，不猜造其与其它回合的关联。
+- 有回合流时正文与工具位置仅来自 item 边界与 `seq`，工具详情按该回合的 `callId` 关联；没有流时同一个回合容器显示历史消息与工具。整轮累计文本仅在活动回合尚无流和持久 assistant 时作兜底，不另建实时消息出口。
+- 同一文本 item 的更新保持位置不变，段切换、工具边界和回合结束冲刷节流内快照；完成事件必须提交完整 item 内容。回合收尾等待已提交的流写入完成，不用磁盘上偶然可见的最后一段推测最终回复身份。JSONL upsert 先合并旧快照，不能先删旧值再“归并”；跨回合保留按回合时间、回合内按 `seq`，不能用各回合从 1 开始的 `seq` 做全局新旧裁剪。
+- 工具输入来自 command / MCP arguments，输出来自 aggregatedOutput / output / result，均经过现有脱敏和长度约束。状态相同但详情更新不能被丢弃。
+- Thread Manager 的原始事件 `seq` 与展示事件的 `sequence` 分开保存，不能将订阅游标用作工具/文本快照的已消费序号。发送队列保存完整结构化输入，上传附件在 Rust 端经过现有校验后并入 canonical user item。
+- 不改变模型、工具执行权限、项目原始历史或业务数据，不进行远程写入。缺失的历史流不得通过删除用户消息隐藏，也不得将已有原始正文截断为流前缀。
+- 验收覆盖：新建回合、工具与文本交替、重复快照、最终落盘、失败/中断、历史重开、分页边界、无流历史及工具输入输出。静态检查不等于实机通过；按用户要求不运行测试时，真实事件/UI 验收单独标为待验证。

+
+DirectProject 的 AGC 工具、构建、验证和浏览器试玩错误，若不属于鉴权、权限、余额、项目身份、历史损坏、传输断开、取消或付费操作状态不确定等安全终止边界，必须作为脱敏错误上下文回传同一 LLM 会话，由 LLM 读取当前项目、修改真实文件并重跑失败阶段。客户端最多连续反馈三次；每次保留 stage、工具 / 命令、错误正文和已有证据，不得静默吞错、伪造成功或用占位产物跳过阶段。达到三次仍失败后，才向用户投影终态错误和诊断引用。

+## 2026-09-16 平台会话身份与凭据分离（并发续期不再中断在途生成）
+
+平台会话在 AGC renderer、原生 Rust 层和独立 Runner 中统一拆成两个互不替代的概念：**身份**（`userId + api origin + identity generation`）与**凭据**（当前 access token）。身份代次只表达登录主体或服务 origin 的更换；凭据轮换必须保持身份代次不变。
+
+- 同一身份内的 access token 轮换 —— 长回合保活、`401` 续期、同一账号重新登录 —— 只更新凭据，不推进身份代次，也不得让任何在途生成、编辑、上传、确认或下载 operation 的冻结会话失效。此前把 token 字节和 native generation 一起当作身份判据，使一次正常续期被等价成换号，在途生图被判为 `authentication-required: 陶泥儿登录态已变化`；本条款取代该判据。
+- 冻结会话的校验判据只包含身份，不含 token 字节。换号、退出或 origin 变化仍然失败关闭：旧身份的 operation 后续一切 POST、poll、下载和结果安装都必须停止，只保留对账证据，不得改绑或重放。
+- 原生 install / clear 继续使用单调 revision 作为写入顺序判据，防止迟到写入复活旧状态；身份代次不参与写入排序，只参与身份归属判定。同身份凭据更新必须携带不小于当前 revision 的新 revision 且保持身份代次不变，才能替换 token。
+- `authentication-required` 只表达"当前 operation 对应的身份已不是权威身份"。同一身份的凭据轮换不得产生该错误。
+- 刷新失败语义：只有服务端明确返回 `401` / `403`，且收敛重试后仍然失败，才允许清除本地会话与 access token。网络错误、`5xx`、网关错误和响应契约异常必须保留既有会话与 access token，只让发起刷新的那个动作失败。
+- 并发刷新收敛：同一 origin 的 refresh 单飞；一次刷新返回 `401` 后允许用当前 refresh cookie 收敛重试一次，重试成功则继续使用新凭据，重试仍为 `401` 才判定登录态权威失效。
+- 服务端 `/api/auth/refresh` 的轮换失败不再下发清空 refresh cookie 的响应。refresh cookie 的失效只由会话吊销、过期或身份变更语义决定，不由一次轮换竞争决定；客户端以"收敛重试后仍 401"作为登出判据。
+- 证据要求：Rust 定向用例覆盖"同身份 token 轮换后冻结会话与在途 operation 仍有效""换号 / 退出后冻结会话失效""迟到 install 被 revision 拒绝"；AGC 前端用例覆盖"续期不推进身份代次""瞬时刷新失败不清会话""收敛重试成功不登出"；`api-server` 用例覆盖"刷新轮换失败不下发清 cookie"。

 ## 2026-09-15 DirectProject 长回合平台会话保活
 
-DirectProject 的生图、素材处理、构建和试玩可能跨越短生命周期 access token 的有效期。普通 `/api/*` 请求和 Codex app-server 已有 401 刷新路径，但 AGC 工具由 Rust 工具桥直接使用客户端当前会话，工具内部的 401 不会自动触发前端刷新。客户端在 DirectProject 回合处于 busy 状态时每 5 分钟调用现有 `requestPlatformSessionRefresh()`；刷新仍复用单飞请求、generation 校验和 native session 安装，不改变凭据来源，也不把 401 降级为成功。刷新失败保持静默，由原始 AGC 工具错误按现有鉴权失败合同返回，避免后台保活覆盖真实错误。

 - 历史记录（已由 V1.1 独立 Runner 替代）：Runtime 最初通过 `resume_game_creator_agent_runtime_tasks` 把本地 JSONL 队列重接到当前 App 进程。当前恢复入口仍保留权限、任务顺序和 `agent.runtime.background_task.recovered` 审计语义，但实际由独立 Runner 接管原 run / session；已发出的上游 LLM 请求仍不能从网络中间点续传。2026-07-27 起，Runner 归 Tauri GUI 生命周期所有，同一 AppData 只允许一个 GUI owner。GUI 启动子进程会显式声明 `--gui-owner-required` 并在就绪后 attach owner；Runner 若在启动检查前已发现 owner 释放则直接失败，不得退化成 CLI-owned Runner。Runner 使用独立 watchdog 线程每 100ms 监控 owner OS 锁，不依赖服务端主循环继续推进；owner 丢失后先触发 1.5 秒共享 deadline 的 draining、Provider 中断和 process session 回收，若主循环或排空链路卡死则在 1.75 秒后由 Runner 自身进程安全硬退出并清理匹配 bootId 的 endpoint。GUI 客户端还必须把完整 `runner.attach_gui_owner` 参数作为绑定规范化 AppData 的进程内登记保存；`ensure_external_agent_runner` 无论复用既有 endpoint 还是启动新 Runner，都要在把 endpoint 交给 Runtime 写请求前按新 `bootId` 补登记。同一登记 generation 在同一 boot 上幂等，补登记失败不得记录成功 boot 且本次 `ensure` 失败关闭；未建立 GUI 登记的普通 CLI 不执行该重放。OS owner 锁与 watchdog 已成立只代表进程受 GUI 生命周期约束，不能替代事件 sink 等进程内附加能力的逐 boot 恢复。因此正常最终退出、panic、SIGKILL 和 setup 中途失败都不会再因 busy 或主循环卡死而残留后台进程。endpoint 缺失 / 读取失败必须结合 Runner 实例锁判断；GUI 客户端强制兜底在 Linux 使用 pidfd、Windows 使用稳定进程 handle。macOS 没有等价稳定句柄，客户端不得在 start identity 检查后按裸 PID 强杀，而由跨平台 Runner 自身 watchdog 提供硬退出兜底。旧 endpoint 缺 start identity 时，只有认证 ping 精确匹配 PID + bootId 才允许迁移 busy 旧 Runner。未完成任务保持 durable 状态并在下一次启动走 reconciliation / recovery，不能伪造 completed 或重放副作用。关闭单个 WebView / 子窗口和普通 CLI 退出不触发该行为，版本切换与人工命令仍可使用只关闭空闲实例的 `runner.shutdown_if_idle`。
 - 2026-08-23 Runner 协议 v7 GUI owner 会话权威补充：GUI 取得 owner OS 锁时产生随机 `owner epoch`，并在私有 AppData 持久化只含 `owner epoch + session revision` 的 claim；每次登录、refresh、退出或换号都必须先单调推进 durable session revision，再同步 Runner。`runner.attach_gui_owner` 是 Runner 接受平台会话快照的唯一授权入口；只有 attach 携带的 epoch/revision 与 durable claim 完全一致才可安装或清除会话，新 GUI epoch 可替换旧进程留下的高 `authGeneration`，不用可在新 WebView 重置的 generation 猜测进程所有权。Runner 在 claim 缺失、不可读或与当前 attach 身份失配时立即清空进程内平台会话，并阻断除重新 attach 及必要管理请求以外的 Runtime 工作；旧 `platform.session.install/clear` 协议不再是授权入口。GUI 会话同步未得到完整 attach 确认时本地变更必须失败，并隔离或停止旧 Runner；即使进程终止失败，claim 失配门禁也不允许旧账号继续发起 Runtime 请求。claim 不保存 Access Token，Token 只随当次受保护的 attach IPC 进入 Runner 内存。
+- 2026-09-16 多窗口更正：同一 AppData 不再只允许一个 GUI 界面进程。原 owner OS 锁改为可被多个界面进程同时持有的参与者锁（`agent-runner.gui-participant.lock`），Runner 以“能否独占取得该锁”判断是否仍有界面进程存活，watchdog 与 attach 门禁都改用该判定。新增窗口默认只**采纳** durable claim（读同一 epoch/revision 并 attach），只有登录、refresh、退出或换号才发布新 claim（新 epoch + 本窗口 revision），因此同 claim 的重复 attach 不再清空平台会话，epoch 变化才允许强制替换。事件接收端从单槽改为按 token 去重的注册表并广播，保证第二个窗口 attach 后第一个窗口仍收到 manifest 失效与 Runtime update relay。claim 一致性与失败关闭语义不变。详见同文档「2026-09-16 AGC 同 AppData 多窗口共享 Agent Runner」。
 - 2026-08-05 GUI owner attachment 确认补充：登记参数必须保存 GUI manifest 事件接收端的真实 `event_sink_port` 与 `event_sink_token`，不得借用 actionId 等无关字段作为测试替身。每次 attach RPC 只有同时返回 `attached=true` 与 `eventSinkAttached=true` 才能把当前 `bootId` 标记为已登记；`eventSinkAttached` 缺失、为 false 或普通 RPC 失败都保持当前 boot 待重试。sink token 只留在私有进程内登记和 RPC 参数中，不进入日志、错误文本或公共状态。

+- 目标：同一个 AppData 可以同时运行多个 AGC 界面进程，它们共享同一个 Agent Runner、同一份平台登录态权威和同一份项目事实，并且都继续收到 manifest 失效与 Runtime update relay。
+- 非目标：不引入多 Runner、不做跨 AppData 的会话共享、不改变渲染层 generation 语义、不修改平台 HTTP 契约、SpacetimeDB schema 与 `/api/external/v1`。
+
+### 参与入口、状态与跨模块边界
+
+- 界面进程持有的 OS 锁改为**参与者锁** `agent-runner.gui-participant.lock`：它以共享句柄打开，任意数量的界面进程可同时持有；Runner、watchdog 与 attach 门禁只做“能否独占取得该锁”的探测，独占成功即表示已无界面进程存活。
+- durable claim `agent-runner.gui-owner.claim.json` 仍是唯一的 owner 授权记录，内容仍为 `ownerEpoch + sessionRevision`；claim 不保存 Access Token。
+- 项目级 `.agent/project.lock` 不变：多窗口共享 Runner 不等于共享项目写权，同一项目同一时刻仍只有一个写者。
+
+### 正常、失败、重试与幂等行为
+
+- 采纳：窗口启动时先读取 durable claim 并以同一 `epoch/revision` attach；claim 缺失或不可读时才发布新 claim。采纳路径不写 claim。
+- 发布：登录、refresh、退出或换号时，窗口写入新 claim（新 epoch + 本窗口 revision）再 attach；同一次发布在多个窗口并发发生时以最后一次成功写入的 claim 为准，落败窗口按最新 claim 重试，重试仍有界失败时向用户暴露错误，不做隐式合并。
+- 幂等：同一 claim 的重复 attach 是空操作，不得清空或替换 Runner 平台登录态；只有 epoch 变化或携带明确登出参数的 attach 才允许替换 / 清空。
+- 失败关闭：attach 携带的 epoch/revision 与 durable claim 不一致、claim 不可读、或 claim 在 attach 提交期间变化时，Runner 继续清空进程内平台会话并阻断除重新 attach 与必要管理请求以外的 Runtime 工作。
+- 事件：manifest 失效与 Runtime update relay 广播到全部已登记接收端（按 `event_sink_token` 去重，发送失败即淘汰该接收端），单个窗口退出或接收端失效不得影响其它窗口。
+- 生命周期：Runner 跟随“是否仍有界面进程存活”，不跟随某一个窗口；全部窗口退出后必须在有界时间内关停并清理 endpoint、释放实例锁。
+
+### 契约与兼容
+
+- 本机 GUI ↔ Runner 协议方法与参数不变；变化只在参与锁语义、claim 采纳/发布时机与事件接收端注册表。
+- 已退役的“同一 AppData 只允许一个 GUI owner”行为不再保留兼容分支；`startup.runner.owner-lock.failed` 诊断分类改名为参与者锁失败，仅在真正无法建立参与锁时出现。
+- 混用新旧版本二进制访问同一 AppData 不属于支持场景：旧版本仍以独占方式持有旧锁文件，可能让新版本判定为“仍有界面进程存活”。
+
+### 验收标准与证据来源
+
+- 定向 Rust 测试：参与者锁可多进程同时持有、全部释放后存活判定为假；同 claim 重复 attach 不改写登录态；epoch 变化才强制替换；两个接收端都收到同一事件；claim 采纳与发布的失败关闭路径。
+- 运行时 smoke：同一 AppData 启动两个真实 GUI，两个进程都完成 `startup.setup.complete`，`--agent-runner` 进程只有一个，关闭其中一个后另一个仍可继续使用 Runner。
+- 边界：项目级写锁继续拒绝两个窗口同时写同一项目；新增日志与错误文案不含 Token、Access Token、API Key 与绝对路径。

+# 【技术方案】GameAgent 对话工具调用卡片（Codex 风格）-2026-09-14
+
+## 一句话交付
+
+把 GameAgent 右侧对话面板里的「执行命令 / 写文件 / 调工具」从一行中文进度文本，改成 Codex 桌面客户端那样的**可折叠卡片**（折叠态一行摘要，展开态看命令与文件明细），并且在**刷新页面、重开项目后仍然存在**。
+
+## 背景与现状（已核实）
+
+- 数据来源：Codex app-server 会推 `item/started` / `item/completed`，item 里带完整信息（`commandExecution.command`、`fileChange.changes[].path` 等）。
+- 现状投影：`apps/ai-game-creator-shell/src-tauri/src/agent/codex_app_server.rs` 的 `direct_codex_item_intermediate_text()`（约 791 行）把 item **压成一行中文文本**（`正在执行命令：xxx` / `正在写入文件：xxx`），经 `DirectCodexTurnObservation::IntermediateText` 下发。
+- 前端事件：`GameCreatorDirectTurnUpdateEvent`（`src/app/types.ts:1090`）只有 `projectPath / turnId / sequence / status / activity / accumulatedText / updatedAt`，**没有结构化工具调用**。
+- 历史持久化：`.agent/conversations/project.jsonl` 现在只写 message 条目（实测 61 条全是 message），工具调用不留痕。
+- 历史回读：`read_direct_project_chat_history_at()`（`direct_project_history.rs:575`）只把 `role ∈ {user, assistant}` 且有文本的条目投影成 `LocalConversationMessageRecord`，**形状上装不下工具调用**。
+- 结论：要做成卡片必须同时改「采集 → 传输 → 持久化 → 回读 → 渲染」五段，纯前端做不出来。
+
+## 契约（实现必须照此，不得自行改形状）
+
+### 1. 工具调用条目（采集与持久化形状）
+
+新增独立历史文件：`<projectRoot>/.agent/conversations/tool-calls.jsonl`，一行一条，行信封与既有历史一致：
+
+```json
+{ "type": "tool_call_item", "payload": { "schemaVersion": "agc-tool-call.v1", "id": "...", "turnId": "...", "kind": "command|file_change|mcp_tool|web_search|context_compaction|other", "title": "执行命令", "summary": "npm run build", "status": "running|completed|failed", "detail": { "command": "...", "output": "...", "changes": [{ "path": "game/src/x.ts", "kind": "add|update|delete" }] }, "startedAt": 0, "updatedAt": 0 } }
+```
+
+- `id`：Codex item 的 id；同一 item 的 `started` 与 `completed` 必须落成**同一条**（按 id 幂等 upsert，不允许写两行）。
+- **状态单调**：同一 `id` 的每条快照按 `updatedAt` 合并落盘——`updatedAt` 更旧的快照不得覆盖更新的 `status` 与 `updatedAt`。逐条快照落盘与回合末整批落盘两条路径会并发竞争，后到的旧快照不能把已经 `completed` / `failed` 的卡片打回 `running`；`updatedAt` 相同时终态优先；`startedAt` 取最早的非零值（`item/completed` 不一定带 `startedAtMs`）。
+- `title` 是折叠态的一行标题，按 kind 固定：`command` → `执行命令`、`file_change` → `编辑 N 个文件`（N = changes 去重后数量）、其余见 kind 枚举。
+- `summary` 是折叠态标题后面的短摘要：命令取命令首行（截断 120 字符），`file_change` 取首个变更路径。`summary` 的每个来源（命令、变更路径、`tool`）都必须先脱敏再落盘。
+- `detail.command` 读取原生命令或 MCP `arguments`，`detail.output` 读取 `aggregatedOutput` / `output` / `result` / `error`；对象格式化为 JSON，先脱敏再各截断到 4000 字符。展开工具行分别显示“输入”“输出”。MCP 摘要保留工具名，不把 JSON 开头的 `{` 当成摘要。状态相同但详情变化也必须更新；完成快照缺少输入字段时保留开始快照的输入。
+- **路径形状**：`detail.changes[].path` 用**项目相对路径**（如 `game/src/x.ts`，分隔符统一成 `/`）；项目外的绝对路径落成 `<absolute-path>` 占位。任何情况下都不得写出项目根目录本身、用户家目录或绝对路径的原始值。
+- **必须脱敏**（落盘前统一走 `agent/direct_tool_calls.rs` 的 `sanitize_detail_text`，顺序：项目路径归一化 → `redact_absolute_path_tokens` → `redact_secret_tokens` → `sanitize_error_context`）：
+  - 前缀型密钥沿用 `redact_secret_tokens`（`sk-…`、`tnr_sk_…`、`ghp_…`、`AKIA…`、`eyJ…` 等）；
+  - 键值型凭据沿用 `sanitize_error_context`（= `redact_secret_tokens` + `redact_error_sensitive_assignments` + `redact_error_bearer_values` + `redact_error_config_names` 的既有组合），覆盖 `Authorization: Bearer …`、`Cookie: session=…`、`api_key=…`、`client_secret=…`、`token=…` 等形状；
+  - 含 `--password` / `--token` / `--secret` / `--api-key` 这类敏感 CLI 标志的行按既有 fail-closed 约定**整行**替换成 `[redacted sensitive context]`（与 `sanitize_agent_runtime_text` 一致；即使标志后面只是 `$VAR` 占位符也整行替换，占位符本身不会保留）；
+  - 脱敏必须幂等（同一段文本连跑两次结果一致），且不得把未脱敏文本写进 `detail` / `summary`。
+
+### 2. 实时事件（新增字段，不改既有字段语义）
+
+`GameCreatorDirectTurnUpdateEvent` 增加**可选**字段：
+
+```ts
+toolCalls?: DirectTurnToolCall[] | null;
+```
+
+- 只有在本回合工具调用集合发生变化时才带（不要每个 heartbeat 都重发全量）。
+- 字段**可选**：老版本事件解析路径必须保持兼容（前端拿到 `undefined` 时行为与现在一致）。
+- `DirectTurnToolCall` 与上面 payload 同形（去掉 `turnId`）。
+
+### 3. 回读命令
+
+新增 Tauri 命令 `read_direct_tool_calls(projectPath)`，返回按时间正序的 `DirectTurnToolCall[]`。
+
+- **上限语义**：200 条是「按时间保留最新 200 条」。超出时更早回合的卡片会被**静默丢弃**（老回合卡片会消失），不做分页、不做历史回填；同一 `id` 的多条记录先按 `updatedAt` 合并，再按时间正序裁剪。
+- 历史文件缺失 → 返回空数组，不报错。
+- 单行损坏 → 逐行读字节并逐行解码，跳过该行继续，不整体失败；只有损坏字节与下一行黏成一行（例如写入被截断、缺失换行）时，被丢掉的也只是那**一行**，其后的合法记录必须继续读回（与 Codex item 流一样是"尽力而为"的展示数据，不是业务真相）。
+
+### 4. 前端合并与渲染（回合唯一归属，连续工具成块）
+
+- 加载对话时按 `turnId` 归并为唯一回合容器，用户消息保留在该回合前部。有 `turn-stream.jsonl` 时，文本与工具按 item `seq` 交替，连续工具合为一块，遇到文本另起一块；没有流的历史回合才采用“工具块 + 历史正文”。
+- 回合完成后，中间文本及所有工具块统一收进默认关闭的“执行过程”；最终回复及失败提示留在外面。展开后仍按原顺序查看中间输出和工具详情；运行中不使用外层折叠区。用户消息的发送时间从消息自身的历史时间读取，不能拿工具起点补造。
+- 实时与回读共用同一投影，正文、工具和耗时不另建实时/未归属渲染出口。先在完整历史按消息身份关联，再分页；禁止按第 N 个工具回合匹配第 N 条用户消息。详情通过当前回合 `callId` 关联；同项目回读与实时增量幂等合并，切项目清空旧状态。完整合同见 [AGC 实施计划](./【技术方案】AI游戏创作智能体App实施计划-2026-06-24.md) 的“DirectProject 回合展示唯一归属”。
+- 块 DOM 与交互（对齐 Codex）：
+
+```html
+<section class="agent-tool-call-group" data-testid="agent-tool-call-group" data-status="completed">
+  <button type="button" class="agent-tool-call-group-head" aria-expanded="false" aria-controls="…"

+        </div>
+      </li>
+    </ul>
+  </div>
+</section>
+```
+
+- 文案规则（按 kind，不允许自由发挥）：
+  - 块头汇总按 kind 计数、顺序固定 `command → file_change → mcp_tool → web_search → context_compaction → other`，标签 `命令`/`文件变更`/`工具调用`/`联网搜索`/`上下文整理`/`其他操作`，形如 `已执行 5 个命令、2 个文件变更`；空集合不渲染块。
+  - 行文案：展示工具摘要，不重复添加动词前缀；`context_compaction` 固定为“整理上下文”。状态单独放在行尾（执行中 / 已执行 / 失败），`failed` 使用现有 `--platform-*` 错误色；已结束回合不因残留 `running` 快照显示“执行中”。
+  - 耗时：单条工具 = `startedAt` → `updatedAt`，块头总用时 = 该回合所有工具的 `min(startedAt)` → `max(updatedAt)`。单条格式：`<1s` → `0.4s`、`<60s` → `12.3s`（整秒省略小数）、`≥60s` → `2m 5s`；块头格式：`42秒` / `4分钟` / `5分钟 45秒`。`startedAt` 为 0 或 `updatedAt < startedAt` 时不显示耗时（不显示 `0s` / 负数），耗时为 0 时同样不显示 `0s`。
+  - 时间：块头显示该回合结束时间（`max(updatedAt)` 的本地 `HH:mm:ss`）；同一回合能拿到用户消息时间（`updatedAt > 0`）时显示 `HH:mm:ss → HH:mm:ss`（发送 → 结束），取不到就只显示结束时间，不编造。
+  - 回合结束时间与耗时在正文下方右对齐；Direct 对话输入框提示统一为“描述你的想法，或 @ 引用素材”，引用按钮保留输入盒的 12px 内边距，不使用负边距贴边。
+  - 当前 Agent 与策划 Agent 共用 `packages/shared` 的 `AgentMessageContent` 表现组件：正文为 14px / `--platform-text-strong`，思考、中间输出和工具调用为 12px / `--platform-text-soft`。实时与历史思考共用同一个折叠入口；工具输入输出继承过程色，失败状态保留错误色。Markdown 标题、表格及代码高亮在过程区同步弱化，最终回复和文档预览仍保留正常排版，不按 Agent 类型复制样式。输入提示与禁用状态保持原有反馈。
+  - Windows 命令展示：仅 `command` 卡片识别 `pwsh` / `powershell`（含完整路径、`.exe`、常见启动选项）的 `-Command` / `-c` 外层包装，摘要和展开输入只展示脚本正文，并解开单个 shell 参数的引用拼接。摘要优先读取已脱敏的 `detail.command`，再按首行 120 字符截断，避免历史摘要被可执行文件路径占满。无法识别的启动方式、`-File`、`-EncodedCommand`、普通命令和 MCP 输入原样展示；执行参数、持久化原文、脱敏和输出均不改变。
+  - 调试属性：块与行都带 `data-duration-ms`（原始毫秒，无法计算时为空串）与稳定 `data-testid`（块 `agent-tool-call-group`、行 `agent-tool-call-row`）。
+- 必须用 `<button aria-expanded>` + `hidden` 控制展开（键盘可达、可读屏），块头与行都是按钮：`aria-label` = 汇总 / 行文案 + 耗时；默认折叠。
+- 输入框、消息气泡、消息列表滚动模型**不变**；块只是消息流里的一个块。
+
+## 验收判据（每条都要有可复现证据）
+
+1. 一轮真实回合里，`tool-calls.jsonl` 里同 id 只有一行，`completed` 后 `status` 变 `completed`。
+2. 刷新页面 / 重开项目后，工具调用卡仍在原位（不重复、不丢）。
+3. 实时回合中卡片状态从 `running` 走到 `completed`。
+4. 折叠/展开键盘可达（Tab 到头部按钮、Enter/Space 切换、`aria-expanded` 同步）。
+5. `Read` 到的既有对话（无工具调用）行为不变；老事件（无 `toolCalls` 字段）行为不变。
+6. 脱敏检查：`tool-calls.jsonl` 里不出现 API Key / Token / 绝对用户目录。
+
+## 不做项（本次明确不做）
+
+- 不做工具调用的重试 / 取消 / 编辑按钮。
+- 不做 diff 级展开（只在展开态列文件路径与变更类型）。
+- 不做工具输出的完整回放、不做卡片内搜索。
+- 不改 `.agent/conversations/project.jsonl` 的既有格式与注入 Codex 上下文的路径（新数据走独立文件，避免污染模型上下文）。
+- 不改工具调用之外的聊天渲染（markdown、气泡、滚动）。
+- 不做历史工具调用的迁移回填（存量项目没有卡片，属预期）。
+
+## 涉及文件（实现边界）
+
+- Rust（`apps/ai-game-creator-shell/src-tauri/src/`）：`agent/codex_app_server.rs`（item → 结构化采集）、`agent/direct_runtime.rs`（随事件下发 + 回合结束持久化）、`agent/direct_project_history.rs` 或新增 `agent/direct_tool_calls.rs`（upsert 与回读）、`commands.rs`（新增命令注册）。
+- 前端（`apps/ai-game-creator-shell/src/`）：`app/types.ts`（新增字段与类型）、`App.tsx`（订阅、累加、加载时合并）、`features/agent-runtime/` 或新增 `features/project-workspace/ToolCallCard.tsx`（卡片组件）、`styles.css`（卡片样式，新样式集中在文件末尾中文注释区块）。
+- 测试：Rust 侧单元测试（upsert 幂等、状态按 `updatedAt` 单调合并、截断、脱敏覆盖与幂等性、项目相对路径形状、非法 UTF-8 损坏行跳过、200 条上限保留最新）、前端 `tests/`（卡片渲染、折叠交互、重开项目后合并、老事件兼容）。
+
+## 实施顺序（每步都要能独立验证）
+
+1. Rust 采集 + 独立文件 upsert：先只落盘，单元测试证明幂等与截断。
+2. 事件字段下发 + 前端类型：老路径不受影响（回归现有 appSurface 用例）。
+3. Tauri 回读命令 + 前端加载合并：刷新后卡片存在。
+4. 卡片组件 + 样式 + 无障碍：折叠/展开 + 键盘。
+5. 真实回合联调（本地 Tauri 起一轮），截图留证。

+
+Git hook 的临时仓库测试必须清除子进程继承的仓库定位环境（例如 `GIT_DIR`、`GIT_WORK_TREE`、`GIT_INDEX_FILE`）；仅设置 `cwd` 不能隔离 Git。回归应从带这些变量的外层仓库运行，验证外层引用、索引与配置不变。临时测试文件必须留在独立目录并清理，不得通过测试生成主仓库提交或覆盖 ESLint、Prettier 配置。修复 lint 配置时保留原有规则、忽略范围与零警告门禁，不以关闭规则代替排障。
+
+链接工作树（`git worktree`）里执行 `git push`、`git commit` 时，Git 会把 `GIT_DIR`（指向该工作树的管理目录）、`GIT_WORK_TREE`、`GIT_INDEX_FILE` 注入 Hook，`npm`、`lint-staged` 与测试夹具整链条继承；夹具的 `git config` 会写到共享 `.git/config`（此后所有提交 author 变成夹具身份），夹具的 `git init` 会重写 `core.bare` 或 `core.worktree`。因此 `.husky/pre-commit`、`.husky/pre-push` 与 `scripts/check-repository-ci.sh` 入口必须 `unset GIT_DIR GIT_WORK_TREE GIT_INDEX_FILE GIT_COMMON_DIR GIT_PREFIX GIT_CONFIG_PARAMETERS GIT_CEILING_DIRECTORIES`，夹具 Git 调用还要自检 `git rev-parse --show-toplevel` 等于夹具目录，落到外部仓库时直接失败。真实仓库被污染后的修复顺序：备份 `.git/config` → `git config --unset core.worktree` → 确认 `core.bare=false` → `git config --unset user.name` 与 `user.email` 恢复全局身份 → 核对 `.git/worktrees/*/config.worktree` → 用 `git checkout HEAD -- .` 回填被劫持期间漏掉的检出（未跟踪文件不动）。
+
+Stdb 发布以 root 准备文件、再切换 `spacetimedb` 用户执行时，WASM 必须放在服务用户可遍历的父目录下。生产脚本在 `/var/tmp` 创建随机私有目录并移交给发布用户，退出时清理；不能仅修改子目录所有权后继续从 `/root` 下读取。发布成功的判据仍是完整 Full Build 的 Stdb、API、Web 发布及退出维护模式全部成功。

 普通图片错误素材类型清理使用 `npm run spacetime:editor-image-asset-kind:clean -- --database <database> --server-url <url>`，只能由已授权 migration operator 执行。先进入维护模式并发布包含 `clean_editor_image_asset_kind_and_return` 的 SpacetimeDB module，并保持旧版本 API / controller / worker 停止；随后运行默认全量 dry-run，核对 `asset → project-resource → showcase → canvas` 各 scope 的扫描数、命中行数、字段数和 blocker 均符合预期，再追加 `--apply`。脚本对每批重新 dry-run、绑定包含画布迁移摘要、结构化 layer 与 generation-dialog 权威 JSON 的 SHA-256，最后自动从头复核零命中；任一画布数据异常都会只输出哈希化 ID、scope 与原因并停止，不能跳过。清理只处理精确业务旧值，不修改 `asset_object.asset_kind`、MIME 或媒体类型；project-resource scope 在清行前验证同工程 migration 并将其状态纳入批次 hash，layout version 0 的 legacy 画布可以没有 migration，但 structured 画布缺 migration 必须立即形成 blocker，资源行不得先被清空；清行后能保持原 status 不变量时立即刷新摘要，否则只允许留给后续精确 canvas 字段清理收口。canvas scope 在任何布局写入前再次按 active / backfilled / rolled_back 状态验证原 migration 凭证和双份 legacy / structured 不变量，将 `editor_canvas_generation_dialog.dialog_json` 与 layer rows 一并扫描并在同一事务 patch；只允许本批资源清零及精确字段删除造成的差异，写入后从全部结构化权威行重建 layout、再次复核新状态才受控重签摘要，同时保持业务 revision、migration status 与全部时间戳不变。新版本 API、SpacetimeDB storage 创建入口、legacy 画布元数据提取和项目资源落表边界都会将 trim 后精确等于 `image` 的 `assetKind` 归一为 `NULL`，防止旧页面、滞留请求或 legacy 保存重新制造废弃值。完成零残留复核，并分别确认 cleaned backfilled 可激活、active 可继续保存、rolled_back 可重复复检后恢复应用版本，最后退出维护。Stdb build artifact 和完整 release 包必须同时包含 `scripts/spacetime-clean-editor-image-asset-kind.mjs` 与 `scripts/spacetime-migration-common.mjs`。
 
-自 2026-07-11 起，`Genarrative-Full-Build-And-Deploy` 的每日 04:00 timer 默认以 `DEPLOY_TARGET=development`、`STDB_API_ROLLOUT_MODE=normal` 对仅供开发使用的 dev 服务器执行 Stdb → API → Web 完整发布，不进入人工 rollout gate。三个下游 Build 都由 Full Job 显式传 `PUBLISH_AFTER_BUILD=false`，不得依赖下游 Job 默认值或提前各自发布；统一 Build 完成后仍由 Full Job 按固定顺序发布。人工维护窗口才选择 `pause-after-stdb`，且必须配置 `STDB_API_ROLLOUT_APPROVERS`。上文“定时构建缺少审批人时失败”的旧口径不再作为当前 dev 定时发布行为。
+`Genarrative-Scheduled-Revision-Trigger` 是唯一的定时入口，每小时检查一次（`H * * * *`，分钟由 Jenkins 按 Job 名散列，不等同于整点）。它只用 `git ls-remote` 解析 `SOURCE_BRANCH`（默认 `master`）的远端 HEAD，不 checkout 工作区；解析出的完整 commit 与上一次触发过的 revision 相同则标记 `NOT_BUILT` 并结束，不触发任何下游。
+
+revision 变化时，调度管线把同一个完整 commit 通过 `COMMIT_HASH` 同时传给 `Genarrative-Full-Build-And-Deploy` 与 `Genarrative-Agc-Windows-Build`，两条管线都按这个 commit 检出（Full Job 继续把 `env.SOURCE_COMMIT` 透传给 Web / API / Stdb 的 Build、Publish、Deploy），因此两个产物必然来自同一个版本，不会各自解析分支 HEAD 造成漂移。两条下游管线自身不带任何定时触发器，也不在管线内部做版本比较。Full Job 默认以 `DEPLOY_TARGET=development`、`STDB_API_ROLLOUT_MODE=normal` 对仅供开发使用的 dev 服务器执行 Stdb → API → Web 完整发布，不进入人工 rollout gate；三个下游 Build 都由 Full Job 显式传 `PUBLISH_AFTER_BUILD=false`，统一 Build 完成后仍由 Full Job 按固定顺序发布。人工维护窗口才选择 `pause-after-stdb`，且必须配置 `STDB_API_ROLLOUT_APPROVERS`。
+
+调度状态是调度 Job 工作区里的 `.jenkins-last-triggered-revision`，构建描述同时回显本次 revision 与结果。工作区被清理（例如 `Wipe Out Workspace`）或状态文件缺失时，下一次运行按“版本变化”处理并触发一次，之后恢复稳定；需要重建同一版本时勾选 `FORCE_TRIGGER`。Job 按仓库内 `jenkins/scheduled-revision-trigger-job-config.xml` 创建：`scriptPath=jenkins/Jenkinsfile.scheduled-revision-trigger`、Git 入口 `ssh://git@127.0.0.1:2222/GenarrativeAI/Genarrative.git`、凭据 `genarrative-local-gitea-ssh`、`<triggers/>` 留空（定时器写在 Jenkinsfile 里）。推送后必须让三个 live Job 各自加载一次新 Jenkinsfile，并只读核对 `config.xml`：Full 与 AGC 不再有 cron，定时只来自新调度 Job；只改 Jenkinsfile 而不确认 live 配置时，旧 cron 仍会继续触发。
 
 Full Job 通过 `EXIT_MAINTENANCE_MODE_AFTER_COMPLETION` 明确选择完整发布成功后是否退出维护，默认勾选以保持历史行为。Full 对 Stdb Publish 和 API Deploy 两个下游阶段都固定传 `KEEP_MAINTENANCE_MODE=true`，让 maintenance marker 持续覆盖 Stdb → API → Web 整段发布；Web Deploy 成功后才进入独立 `Exit Maintenance` 阶段。该阶段只能通过 `agent none` 和显式 `node(...)` 分配目标机，直接执行 `/opt/genarrative/current/scripts/deploy/maintenance-off.sh`；目标机不得 checkout Git、挂载 Git SSH 凭据或依赖 Jenkins workspace 源码。取消勾选时跳过最终退出阶段，便于内网验收完成后人工恢复公网。`Genarrative-Api-Deploy` 也单独暴露 `KEEP_MAINTENANCE_MODE` 参数，并转换为随发布包脚本的 `--keep-maintenance-mode`；失败路径仍按既有 current 切换边界保留或退出维护，不受成功态选项覆盖。外部生成 queue 的 `warning` 由 API/worker 固化为可直接展示的完整文案，Web 不再补前缀，因此 API/worker 与 Web 必须在同一维护窗口按同一版本协调发布；分开运行 Job 时先保持维护态完成 API/worker，再发布 Web，二者完成后才能恢复公网，不得在公网可用期间只滚动其中一侧。

 ## 维护模式只拦截公网流量
 
 Nginx 与 Pingora 在维护 marker 存在时对内网来源绕过整站维护闸，主站页面与静态资源、普通 API、后台页面与 `/admin/api/**`、SpacetimeDB 路由均按非维护状态继续处理；公网应用主站、普通 API、后台和 SpacetimeDB 路由继续返回维护响应。内网范围为 IPv4 loopback / RFC1918 / link-local 和 IPv6 loopback / ULA / link-local。Nginx 只按 TCP `$remote_addr` 判定；Pingora 只按 TCP peer 判定，peer 为 loopback 的同机 Nginx 时才读取 Nginx 强制覆盖的 `X-Real-IP`，绝不能把客户端可伪造的 `X-Forwarded-For` 用作维护放行依据。应用本身的登录、管理员鉴权和其它业务鉴权不变。
