+Use `agc_browser_playtest` from the `agc_tools` MCP server to collect runtime evidence.
 
 ## Workflow
 
 1. Call the tool after the current game files are ready to run. The attempt number is client evidence metadata; choose whether another run is useful from the returned facts.
 2. Inspect both desktop and mobile results, including page readiness, visible text, screenshots, console errors, exceptions, failed requests, Canvas probes, blocked actions, and interaction evidence.
 3. Compare screenshots with the user's request. Check that the active game fills its intended area, HUD elements do not cover gameplay, controls are visible, and requested platform art appears in the core experience.
-4. If evidence exposes a defect, edit the actual game files and call the tool again when that is useful. The client enforces its own execution and resource bounds; do not invent a fixed repair loop in the response.
+4. If evidence exposes a defect, edit the actual game files and call the tool again when that is useful. Follow the client's execution and resource bounds.
    Feed the structured diagnostics, console errors, failed requests, and exception text back to the same LLM repair turn before reporting the playtest as failed. Treat the evidence as debugging input and rerun the affected stage after a real code or project change.
 5. Treat browser infrastructure failure, an unloaded page, an unhandled exception, or missing evidence as a failed validation. Do not claim success from a partial result.
-6. Use game-specific reasoning for quality. Do not require a fixed board, fixed text, fixed number of slices, or a legacy harness scenario; the tool result is evidence for Codex to interpret.
+6. Assess quality against the current game's brief and the returned evidence.

 1. Write executable source to `index.html`, `style.css`, and `game.js` in the current cwd. Use only relative paths returned by approved tools for media.
 2. Before using or deriving an existing registered asset, call `agc_list_registered_assets` and select its `localAssetId`. If the user points to an existing project file that is not listed, first call `agc_list_project_files`; only entries with `assetImportable=true` (recognized image, font, audio, video, document, code, or engine asset such as a Cocos `.glb`/`.prefab`/`.anim`/`.mtl`/`.plist`/`.texture`) may be passed to `agc_import_account_assets.localPaths`. Then re-read `agc_list_registered_assets`; never infer a source identity from a filename or fabricate a localAssetId.

+3. Keep read scopes separate: `asset.list` is the current project manifest, `asset.library.list` is the signed-in account library, and the web project's canvas resource read model is the authoritative canvas list.
 4. Use `canvas.asset_import` for safe account/canvas asset IDs or project-relative local paths. The client rechecks ownership and validates bytes; host absolute paths require native UI file-picker authorization.
 5. When the user explicitly asks to create or derive video, character animation, sound effect, or background music, call `agc_create_or_derive_resource`. Use `create` only for video/audio without a source and `derive` with a registered `sourceLocalAssetId`; character animation is always derived from an image. Keep `prompt` inside the per-kind limit that the client really enforces: background music at most 140 characters, sound effect at most 1900, video and character animation at most 4000. A longer prompt is rejected before submission, so write the short version first instead of retrying the same text.
 6. When the user explicitly asks to remove an image background, call `agc_remove_background` with a registered image `sourceLocalAssetId` and `assetName`. Optional `backgroundMode` is `complex` (semantic foreground segmentation; default) or `flat` (solid-colour background removal). Prefer `flat` when the background is known to be solid. Only `flat` accepts optional `screenColor`: `auto`, `#RRGGBB`, or omitted for automatic detection by the service. Do not select a colour on behalf of `auto`. The client requires the signed-in account, owns canvas/folder context and task identity, waits for the accepted operation, downloads and registers the completed local asset, and preserves the operation for recovery when the remote result is not yet known.
 7. Preserve existing relative paths when a small edit is sufficient so client resource identities remain stable.
 8. Do not edit `.agent/manifest.json`, revision counters, version records, resource IDs, canvas identities, source provenance, generation ledgers, or browser receipts by hand.
-9. Do not create a version when no game file changed. The client compares content fingerprints and advances revision only after an actual source change.

Its `assetImportable` field is true for the file types accepted by the current local registration contract: PNG/JPEG/WEBP/GIF/SVG/AVIF/BMP/TGA/TIFF/HDR images, TTF/OTF/WOFF fonts, MP3/WAV/OGG/FLAC/M4A/AAC/OPUS/PCM audio, MP4/WEBM/MOV video, recognized text documents, recognized source-code files, and engine (Cocos Creator) assets such as `.glb`/`.gltf`/`.fbx`/`.mesh`/`.skeleton` models, `.anim`/`.animation`/`.animgraph`/`.animgraphvari`/`.animask` animation clips, `.scene`/`.fire`/`.prefab`/`.tmx`/`.terrain`, `.mtl`/`.material`/`.pmtl`/`.effect`/`.chunk`, `.plist`/`.labelatlas`/`.atlas`/`.fnt`/`.pac`, and engine containers such as `.texture`/`.cubemap`/`.rt`/`.dbbin`/`.bin`/`.skel`/`.psd`/`.znt`/`.exr`. `asset.list`/`kind` filtering classifies models as `model` and undecodable engine containers as `binary`; both are discovery categories, not manifest kinds. Registered engine assets are read-only previews on the resource canvas — models render a thumbnail, serialized assets show a structure summary, and containers that the client cannot decode show a type card. `agc_import_account_assets.localPaths` is the controlled bridge that validates and registers an importable project-local resource. `agc_list_registered_assets` remains the authoritative Direct read path for manifest resource identity; only its stable identifiers may be passed to generation/derivation tools.
 
-Read scopes remain separate: `asset.list` is the current project's local manifest, `asset.library.list` is the signed-in account library, and the web project's canvas resource read model is authoritative for resources visible on that canvas. A library result must not be presented as the complete canvas list. `canvas.asset_import` accepts safe account/canvas asset IDs or project-relative local paths; receipts expose only bounded counts, safe IDs, relative paths, sources, redacted failures, and `revisionAdvanceCount`.

 `agc_create_or_derive_resource` accepts only semantic intent. The client resolves `sourceLocalAssetId`, creates stable request identities, recovers matching pending operations, serializes paid submissions, writes supported media into the current canvas and same-name asset folder, validates downloaded bytes, commits the local manifest transaction, and returns redacted warnings. A tool error or timeout is not permission to generate again with a new identity.
 
-`prompt` limits are per kind and are enforced before any paid submission: background music accepts 1-140 characters, sound effect 1-1900, video and character animation 1-4000, and image editing (`agc_edit_image`) 1-32000. The client composes the submitted request from a fixed prefix plus your prompt, so an over-limit prompt fails locally with the exact limit; shorten the text rather than resubmitting the same value. `agc_edit_image` remains the image path; this tool never generates or edits still images.

Shorten an over-limit prompt to the limit returned by the client. Use `agc_generate_image` to generate still images and `agc_edit_image` to edit them.
 
-`agc_remove_background` accepts a registered image `sourceLocalAssetId`, `assetName`, and optional `backgroundMode` and `screenColor`. `complex` uses semantic segmentation to identify the foreground; `flat` removes a solid-colour background. Prefer `flat` when the background is known to be solid; omitting the mode selects `complex`. Only `flat` accepts a colour: `auto`, `#RRGGBB`, or omitted for automatic service detection. Never infer a concrete colour for `auto`. Empty or invalid values and colour without `flat` are rejected. The client resolves the formal source resource, canvas/folder context, stable operation identity, idempotency key, and authenticated request. Ordinary account mode maps the External v1 shaped route to `/api/editor/images/background-removals`; ExternalDeveloper mode uses `/api/external/v1/editor/images/background-removals`. Mode and colour are part of request identity. After acceptance, the client polls the authenticated generation status route, downloads the completed media, and commits it to the local manifest. If completion is unknown, it retains the same local operation for recovery; it never retries with a new identity or exposes internal worker details.

After the tool returns, wire its relative paths into the game and verify the rendered result. A game with unused generated assets or placeholder emoji/CSS where requested art should appear is not complete.

+1. Inspect existing `assets/` and registered project evidence before requesting new art. Reuse suitable assets when they satisfy the current brief. If required visual elements are absent or unsuitable, call the appropriate generation tool during the same game implementation task.
 2. For one new image, call `agc_generate_image` with `kind="image"` (or `character`, `icon-spec`, `ui-prototype`, or `publication-material` when that is the explicit intent). For changes to an existing registered image, call `agc_edit_image` with its `sourceLocalAssetId`; do not fake an edit with a new-image request. For a complete game-art package, call `taonier_prepare_game_art` only when the current intent requires new or recoverable platform art. Use `mode="regenerate"` only after the latest User message is a standalone reviewed immediate-confirmation command such as `请重新生成美术`; punctuation may end it, but no brief, condition, negation, alternative, cost qualifier, deferral, or other text may accompany it. Describe the desired style and gameplay constraints in an earlier non-billable turn, then obtain the standalone confirmation turn; otherwise use `mode="reuse-or-create"`. Quoted UI copy or examples, explanations, questions, historical wording, model/MCP arguments do not authorize regeneration. Pass a concise game-specific visual brief that names the required gameplay entities, background exclusions, tiling needs, and viewport constraints. Do not call either generation tool for greetings, date questions, or text-only code fixes.
 3. Treat the tool result as authoritative. Read `mode`, `assetPaths`, `slicePaths`, `resources`, and every entry in both `warnings` and `sliceWarnings`. `resources` is the client's safe projection of registered Canvas identities; use only its returned relative paths and identities. Never invent a resource, slice, platform identity, warning-free result, or successful regeneration.
 4. A newly created or explicitly regenerated standard package is complete only when `slicePaths` contains the four canonical independent slices. An empty or partial `slicePaths` result never satisfies an independent-asset requirement: if a `sliceWarning` reports too many or unusable elements, narrow the edit/generation brief or generate the needed independent images and continue the integration; do not guess atlas coordinates, fabricate derivatives, or silently fall back to placeholders. A trusted legacy complete sheet may still be used without slices only when the current request does not require independent assets.
 5. Inspect the returned background, complete sheet, and available slice previews before integrating them. Then use suitable returned runtime assets in the game's actual visible experience and confirm their visible use in desktop and mobile playtest evidence. The implementation is incomplete while generated assets remain unused, are referenced only by documentation, or are replaced by emoji, CSS shapes, or other placeholders where the brief requires the generated art. `art-spec.png` is a reference specification, not a runtime background, character, prop, or effect. Background exclusions, seamless tiling, entity semantics, and final draw dimensions are visual/runtime acceptance checks; a prompt alone does not prove them. A hidden or side-panel preview does not count as gameplay use.
-6. Preserve warning details in the final report. If the tool reports missing credentials, uncertain operation state, invalid provenance, download failure, or decode failure, stop and report the actionable reason; do not substitute generated CSS shapes and call the platform step complete.

Recovery completes a new contract only when its receipt identity matches that retained result and the current spec/background match this workflow's replacement anchors. Compensation requires the exact frozen old contract; classification, the `compensating` marker, restoration, verification, and anchor cleanup stay under one project lock, including restart. Any foreign, mixed, or drifted state fails closed without another paid submission.
-- If crash recovery proves a complete new contract but cannot reconstruct stage warnings that were not yet durably attached to the completed result, it must return an explicit recovery warning instead of silently claiming that no warnings occurred.
+- If crash recovery cannot reconstruct the completed result's stage warnings, preserve the returned recovery warning in the report.
 - A newly created or regenerated standard spritesheet must commit exactly four canonical transparent slices with unique pixels and unique Canvas resource/asset identities. Legacy slices are projected only when the client-private receipt, public slice manifest, current source image, local bytes, and top-level registrations agree.
-- If a durable prepared or accepted operation belongs to a different brief, the client must report an unknown/reconciliation result and must not submit a replacement request. Retry or regeneration is not a substitute for reconciling the original operation.
+- If a durable prepared or accepted operation belongs to a different brief, stop and report the unknown/reconciliation result so the original operation can be reconciled.
 - A submission acknowledgement is not a completed image.
 - On timeout or uncertain delivery, reuse the recorded operation; never create a replacement request.
 - `postprocess-failed-source-preserved` means the complete provider source remains usable, but the requested transparent derivative is absent.
 - `sliceWarning` means the complete transparent sheet remains usable, but individual slices are absent.
-- For direct `agc_generate_image` spritesheet requests, `sliceMode` is required and has no default: `connected-components` selects alpha-connectivity detection, while `grid` uses the caller-provided `gridX` and `gridY` (1-32 each) and is only correct when the requirement names equal grid cells, fixed slots, or a concrete column/row count. `connected-components` must not carry `gridX`/`gridY`, and `sliceMode` must not be sent for another `kind`; the client rejects a missing, contradictory, or misapplied declaration instead of choosing a mode. The client preserves the selected mode and grid dimensions in the request identity and result metadata.
+- For `agc_generate_image` with `kind="icon-spritesheet"`, choose the required `sliceMode` from the brief: `connected-components` selects alpha-connectivity detection; `grid` accepts `gridX` and `gridY` (1-32 each) when the requirement names equal grid cells, fixed slots, or a concrete column/row count. Pass grid dimensions only with `grid`, and `sliceMode` only with `icon-spritesheet`. Read the selected mode and dimensions from the returned metadata.
 - The client-owned standard art package declares `sliceMode="connected-components"` with `sliceCount=4` because its four canonical slices are mapped to fixed usage paths: the platform must return exactly four slices or fail with an actionable `422` naming the recognized count, and the client refuses to write a usage manifest whose slice count is not exactly four. A `sliceMode` or grid-dimension echo that disagrees with the request also fails closed before local commit.
 - General and slice warnings can coexist. The tool returns them separately through `warnings` and `sliceWarnings`; callers must preserve every entry and must not downgrade a slice warning into a successful independent-asset claim.
 - `assetPaths` contains the complete package paths. `slicePaths` contains only slices that the client downloaded, validated, and registered with their platform source identities.

- * Agent 协作：1」永远是 1——它把 D11 的「总控 + 委派子 Run」拓扑整个漏给了用户，而
- * 用户的心智模型是在跟一个策划聊天。状态本身由顶部的 `PlanGddStageProgress` 承担。
- *
- * 这里只画真正需要用户动手的两样：澄清问答卡，以及失败后的恢复入口。其余时候
- * 返回 null，不占一行。
- *
- * 完整面板在 `waiting-for-user-input` 却读不到 `userInputRequest` 时会画一句
- * 「待回答问题未能读取」。策划链路里这个组合出现在子 Run 退出到父 Run 醒来之间的
- * 瞬时窗口，以及审批等待（交互面是审批卡）——两种都不是读取失败，所以这里不画。

-   `padding-bottom: 12px`，二是下面窄屏块之前可能出现的任何底边偏移。

-   在输入盒回到文档流之后，那段留白会变成凭空多出来的空白，把最后一条消息顶出可视区。
-   所以：列表底边归 0 留白；它靠 `flex: 1 1 auto` 吸收剩余高度，是整块面板里唯一的滚动区。
-   要改列表底边只改这一段，不要再在别处写第二条同选择器规则。 */

+| Status | ready |
+| Owner | Codex |
+
+## 一句话交付结果
+
+删除退役策划 V1/V2 及其耦合的 Supervisor 产品残留，让当前 Design Agent 独立运行、做游戏走 DirectCodex 并恢复仓库编译；保留通用 Supervisor 和做游戏 16 Agent DAG。
+
+## 验收判据
+
+当前分支能够通过 AGC 前端 typecheck 和受影响定向测试；Design Agent 的新建、恢复、澄清、阶段审批和 reasoning 展示仍由当前 Design Agent 链路完成；旧 V2 IPC、旧 GDD 类型和旧前端测试契约不再存在。
+
+## 修改边界
+
+允许修改：
+
+- `apps/ai-game-creator-shell/src/App.tsx` 中旧 V2 状态、helper、IPC 分支和旧 UI props。
+- `apps/ai-game-creator-shell/src/app/types.ts` 中旧 GDD 类型。
+- `apps/ai-game-creator-shell/src/features/project-workspace/planningSessionV2.ts` 及其直接调用方。
+- `apps/ai-game-creator-shell/tests/appSurface/harness.ts`、`home.suite.ts`、旧策划事件测试。
+- `apps/ai-game-creator-shell/src/styles.css` 中只属于旧 Plan GDD / planning lane 的样式。
+- 没有现役调用方的旧策划身份 fixture、注释和文档索引。
+- 为通过编译所需的最小共享残留删除或改名。
+
+明确不修改：
+
+- `directCodex` 主链路和当前 Design Agent。
+- 16 Agent DAG、`supervisor-swarm` 测试和通用 Runtime 编排；只处理删除策划耦合后直接造成的编译错误。
+- 当前 Design Agent Rust runtime、Design Agent 资源包和 Design Agent IPC 协议。
+- 公开 API、SpacetimeDB schema、迁移和历史持久化数据格式。
+
+## 实现顺序与提交拆分
+
+### 提交一：解耦 Design Agent 状态命名
+
+- 将新版 Design Agent 实际使用的 `planningV2*` transient reply、reasoning、active ref 和相关 lane 控制改成 Design Agent 专属状态。
+- 保持行为不变，不删除旧 V2 会话代码。
+- 验证：AGC typecheck、`git diff --check`。
+
+### 提交二：删除 App 旧 V2 会话控制流
+
+- 删除仅服务旧策划的 Supervisor 产品入口、恢复、轮询和聊天提交分支。
+- 删除旧 V2 session/GDD 状态和 helper。
+- 删除项目打开、消息发送、问询回答、审批和旧流式事件分支。
+- 将“做方案”只连接到当前 Design Agent hydrate/continue/decide 路径，将“做游戏/做素材”只连接到 DirectCodex。
+- 保留 `planningStartMode` 作为入口路由字段，避免无关扩大重命名。
+- 验证：AGC typecheck；必要时运行 App 启动相关定向 suite。
+
+### 提交三：删除旧 TypeScript 适配层和类型
+
+- 删除 `planningSessionV2.ts`。
+- 删除 `PlanGddDecisionAction`、`PlanGddStateViewV1` 及所有直接导入。
+- 重新执行旧符号检索，确认没有残留调用方。
+- 验证：AGC typecheck、`npm run check:encoding`、`git diff --check`。
+
+### 提交四：清理测试、事件契约和 CSS
+
+- 精确删除 harness 中旧 V2/GDD 工厂、mock、调用记录和导出。
+- 精确删除首页 suite 中旧 V2 IPC 断言。
+- 删除旧 `planning-session-v2-stream` 事件测试。
+- 删除 Plan GDD、GDD 审批卡和 planning lane 专属 CSS 及过时说明。
+- 验证：appSurface 定向测试、事件订阅定向测试、AGC typecheck、编码和 diff 检查。
+
+### 提交五：收口确定失效的身份残留和文档入口
+
+- 只处理因 V1/V2 退役而确定失效的旧身份展示、测试 fixture、注释和文档索引。
+- 不扫描或重构做游戏 DAG；共享代码只在其旧策划用途已确定死且删除能直接解决编译/测试问题时处理。
+- 验证：旧策划符号定向检索、相关测试、编码和 diff 检查。
+
+## 验证命令
+
+1. `npm --prefix apps/ai-game-creator-shell run typecheck`
+2. `npm run check:encoding`
+3. `git diff --check`
+4. `npm --prefix apps/ai-game-creator-shell exec vitest run tests/appSurface.test.ts`
+5. 受影响 Rust 文件变化后运行 `cargo check --manifest-path apps/ai-game-creator-shell/src-tauri/Cargo.toml`
+6. 完成全部提交后再次执行旧策划符号检索，并核对 `git status` 与提交边界
+
+## 风险与回滚点
+
+- 最大风险是新版 Design Agent 复用了旧变量名；必须先完成提交一，再删除旧 helper。
+- `ProjectSupervisorView` 已经移除旧 GDD props，App 传参残留会在提交二中一并删除。
+- 测试 harness 同时服务通用总控和 Design Agent，必须局部删除旧 mock，不能整段重写。
+- 若某次提交导致 Design Agent 测试失败，只回滚该独立提交，不恢复旧 V2 兼容层。
+
+## 完成后的临时文档处理
+
+全部里程碑验收通过后，删除本里程碑和实施计划两份临时文档；把仍然有效的长期边界同步回现行 Design Agent 技术方案和项目记忆，不保留阶段性提交步骤。

+
+## 目标
+
+移除旧版策划 Agent V1、V2 的前端会话、审批、数据适配、测试契约和确定失效的展示残留；仅在删除策划链路时遇到已退役 Supervisor 功能耦合时一并删除该耦合，使“做方案”只使用当前 Design Agent、做游戏只使用 DirectCodex。
+
+## 范围
+
+- 解除当前 Design Agent 与旧 `planningV2` / `PlanGdd` 状态命名和控制流的耦合。
+- 删除仅服务旧策划的 Supervisor 产品入口、会话恢复、Runtime 轮询和聊天提交分支；保留通用 Supervisor 与做游戏 DAG。
+- 删除旧 V2 会话 hydrate、start、continue、审批和用户问询分支。
+- 删除旧 V2 TypeScript 会话适配层、旧 GDD 前端类型、测试 mock、旧事件契约和专属样式。
+- 清理确定没有现役调用方的旧策划身份说明、测试 fixture 和文档当前入口。
+- 保留当前 Design Agent 的会话、澄清、阶段审批、工作区浏览和 reasoning 展示行为。
+
+## 不在范围内
+
+- 不主动扫描、重构或整体删除做游戏 Agent 的 16 Agent DAG；只有策划删除直接造成编译或测试失败时才做最小修复。
+- 不删除 DirectCodex 或当前 Design Agent；必要时保留被两者复用的中性聊天表现组件。
+- 不为旧项目新增兼容层、迁移器、墓碑注释或退役行为测试。
+- 不修改 SpacetimeDB schema、公开 API、持久化迁移和现役 Design Agent 协议。
+
+## 依赖与前置条件
+
+- PR #159 的合并提交 `3d8e0211` 代表旧 Fast GDD / 策划 V1 的引入。
+- PR #305 的合并提交 `04128eb6` 同时包含 V1 大范围退役、策划 V2 会话链路和后续 Design Agent 迁移。
+- 当前分支已经删除 Rust V1/V2 Runtime 模块和旧审批组件，但前端仍残留旧 V2 调用方；实现前须保持工作树干净。
+
+## 验收标准
+
+- [ ] “做方案”入口和已有 Design Agent 项目只调用当前 Design Agent IPC，不再调用旧 `planning_*_v2` IPC。
+- [ ] 当前 Design Agent 的消息、reasoning、澄清、阶段审批和重试行为不依赖旧 V2 状态变量。
+- [ ] 源码中不再存在旧 V2 TypeScript 会话适配层、旧 `PlanGdd` 类型和旧前端审批契约。
+- [ ] 旧前端测试、事件测试和样式残留被删除或改为当前 Design Agent 契约。
+- [ ] 不主动修改做游戏 Supervisor + 16 Agent DAG；因共享退役代码删除产生的编译错误得到最小修复。
+- [ ] 前端 typecheck、相关定向测试、编码检查和 diff 检查通过；触及 Rust 时对应 cargo check 通过。
+
+## 证据要求
+
+- 自动化：`npm --prefix apps/ai-game-creator-shell run typecheck`、相关 appSurface 定向测试、`npm run check:encoding`、`git diff --check`。
+- 运行时：至少验证“做方案”新项目进入 Design Agent、已有 Design Agent 会话恢复、澄清/审批回合可继续。

+
+## 目标与范围
+
+修复实际项目自动上传的已证实故障，并让有权限的后台管理员按项目查看远端快照、一键下载按原始目录还原的工程 ZIP。
+
+## 不在范围内
+
+客户端上传 UI、跨设备恢复、版本历史、数据库 schema、线上部署、自动补传全部未打开项目。
+
+## 依赖与前置条件
+
+延续现有私有 OSS 项目快照、平台会话与后台权限。真实 bucket 已只读确认只有两份历史模板清单；上传根因必须经确定性复现后修正。
+
+## 验收标准
+
+- [ ] 正式项目窗口可被同步调度识别；周期与关闭触发保持有界，失败有项目级诊断。
+- [ ] 未单独配置快照目标时仍使用 agc-dev，只复用资源存储凭据；显式快照目标保持有效，不迁移现存对象。
+- [ ] 后台列表显示项目名/ID、用户 ID、同步时间、文件数、体积和完整性，支持刷新与分页。
+- [ ] ZIP 按清单还原相对路径；不含对象存储摘要目录；空文件可上传与导出。
+- [ ] 清单名称/完整性变化在无内容差异时也提交，partial 可恢复 ready，历史缺字段不冒充 ready。
+- [ ] 缺失、损坏、越界路径和非完整清单失败关闭；历史未声明完整性的清单明确标记，允许导出已有文件但不称为完整工程。
+- [ ] 无后台权限不能读取项目或 ZIP；不泄漏凭据；ZIP 构建有体积、并发和临时文件清理边界。
+- [ ] 定向 Rust 测试、后台类型检查/构建、UI smoke、编码、文档索引和 diff 检查完成，运行时证据与未验证部分分别列出。
+
+## 证据要求
+
+自动化覆盖窗口身份、上传零字节、清单统计、目录还原、路径与校验和校验、后台路由权限。运行时优先只读现有 OSS 清单；测试不上传真实用户工程、不修改线上数据。
+
+## 已取得证据
+
+| 层次 | 结果 |
+| --- | --- |
+| 客户端 Rust `project_snapshot` | 22 通过、1 忽略（写入式真实上传 smoke 未运行）；含排队退出等待回归 |
+| 客户端前端生命周期与启动器 | 3 文件、10 测试通过；完整 AGC typecheck、skill-pack、check-config 通过 |
+| 后台页面、API client、路由与样式 | 44 测试通过；admin-web typecheck/build 通过 |
+| 后端快照与权限 | 14 定向测试通过；未认证路由矩阵与页签映射 2 测试通过 |
+| 默认存储目标 | 真实 AppConfig::from_env 配置回归 1 通过 |
+| OSS 存储层 | 全量 55 测试通过，含签名、特殊字符路径、读取上限与零字节 |
+| 真实 OSS 只读导出 | `project_snapshots_live_readonly_list_and_archive` 通过；limit=1 分页、2 清单、12 文件、73,424 字节，ZIP 解压路径/长度/摘要全匹配、临时文件清理通过；两份均为历史 unverified |
+| 浏览器 smoke | 模拟 API 的 1280 桌面与 390 窄屏通过；下载按钮可见，无整页横向溢出；中文 ZIP 文件名、Authorization、409 错误呈现通过 |
+| 通用门禁 | 编码、文档索引、production-ops、Rust 格式、客户端 Prettier 与 diff 检查通过 |
+
+## 剩余验证与环境边界
+
+`npm run dev:api-server -- --api-port 4198 --bgfilter-worker-port 4199 --api-timeout-seconds 600` 编译成功，但当前工作区配置的本地数据库 `xushi-p4wfr` 在 `127.0.0.1:3101` 返回 404，启动认证投影无法完成，故 `/healthz` 及完整 HTTP smoke 未通过。仅本任务启动的 API/worker 已停止；没有清库、迁移数据库、改 `.env` 或替换其它项目的验证目标。
+
+尚未替换安装版、构建新客户端发布包或部署；提交推送按用户本轮授权执行。当前条款已有上述自动化与只读存储证据，最终验收仍等待当前工作区数据库就绪后的 HTTP 联调，以及新客户端的隔离实机自动上传验证；完成后再关闭里程碑并清理两份计划。

+## 2026-09-20 Rust 工具链升到 1.98.1：仓库侧四处同步 + runner 镜像必须重建
+
+- 背景：macOS 27（CLT for Xcode 27.0）冷构建时 proc-macro dylib 被链接成畸形 Mach-O（`mis-aligned LINKEDIT string pool`），上游 rust-lang/rust#157750 已修复，而仓库锁的 stable `1.96.0` 仍复现（Issue #431）。
+- 决策：根 `rust-toolchain.toml` 的 channel 由 `1.96.0` 改为 `1.98.1`；`deploy/container/gitea-ci-job.Dockerfile` 的 Rust stage 由 `rust:1.96-bookworm@sha256:19817ead…` 换成 `rust:1.98-bookworm@sha256:93ce27a88655056a51dbdd8f5f2d7ddc071c7b0070fb288a37b5a285fc83971e`（按 registry 配置实测该 digest 的 `RUST_VERSION=1.98.1`，与 channel 逐字一致）。
+- 决策（版本标签）：镜像 tag / label 一并从 `20260807.1`、`2026.08.07.1` 升为 `20260920.1`、`2026.09.20.1`（同一次核对发现 Dockerfile 里有两处 `org.opencontainers.image.version`：一处 `2026.07.23.1`、一处 `2026.08.07.1`，后写的覆盖先写的，本次一并统一为 `2026.09.20.1`）（`scripts/gitea-ci-job-image.sh`、`deploy/container/gitea-ci-job.Dockerfile`），`deploy/container/README.md` 与开发运维文档同步 digest、Rust 版本和归档示例名。镜像内容变了却沿用旧 tag，排障和回滚都会认错版本。
+- 不变口径：镜像继续 `RUSTUP_AUTO_INSTALL=0`，job 现场不下载工具链；`scripts/check-gitea-ci-job-image.sh` 仍按 `rust-toolchain.toml` 的 channel 逐字校验镜像内工具链名，所以基础镜像的 `RUST_VERSION` 必须与 channel 完全相同。`std::os::windows::fs::MetadataExt::number_of_links`（rust-lang#63010）在 `1.98.1` 上实测仍未稳定，`#[cfg(windows)]` 侧继续使用自行声明 `ByHandleFileInformation` 的实现。
+- 新增护栏：`scripts/project-ci-workflow.test.ts` 增加一条一致性用例——Dockerfile 的 `ARG RUST_IMAGE` 版本段必须等于 `rust-toolchain.toml` 的 channel 主次版本、其 digest 必须同时出现在两份运维文档里、镜像 tag 日期戳必须与 Dockerfile 的 `org.opencontainers.image.version` 一致，避免本次这种「改了 Dockerfile 忘了文档」的漂移。
+- 待办（不在本次仓库改动内）：在 station 上执行 `build / verify / export / load-runner`，备份 runner config 后把 `genarrative-ci` 映射切到新 Image ID 并 `docker restart --timeout 660 gitea-runner`；内层只有 1.96 时 PR 的 job 必然失败。macOS 与 Windows AGC 构建机（`jenkins/Jenkinsfile.ai-game-creator-shell-build`，preflight 只校验 rustc/cargo 是否存在）需确认已装 `1.98.1`，macOS 冷构建是本次问题的原始验证目标。`deploy/container/api-server.Dockerfile` 的 `FROM rust:1.93-bookworm` 是另一处未加 digest 的 Rust 版本 pin，本次未动。
+- 验证：分支 `chore/rust-toolchain-1-98` / PR #432；`npx vitest run scripts/project-ci-workflow.test.ts`、`npm run check:encoding`、`git diff --check` 通过。Windows：`1.98.1` 下 `npm run agc:build -- --debug` 的前端构建、Rust 编译与 NSIS 安装包生成成功（见 PR 描述记录）；macOS 与镜像重建后的 CI 结果仍待验证。

+
 AGC 运行时配置默认值调整时，同步核对 Rust 默认值、分发配置模板、设置弹窗默认草稿和 `runtime-settings.suite.ts` 的恢复默认断言；显式传入旧值的配置读取用例仍验证原值保留，不批量替换测试数据。
 
 AGC 测试构造单 HTML 项目时，必须在初始化之前写入 HTML，避免自动建立 npm 工程；npm 预览和导出测试应提供 dist 产物。已有图片生成 pending/operation 属于持久化恢复合同，修改工具默认参数后仍须验证旧动作恢复不重复提交、不因默认值变化被误判为新意图。
 
 SpacetimeDB 任务统一先读取 `.codex/skills/genarrative-spacetimedb/SKILL.md`；该项目适配层按需调用已安装的官方 `spacetimedb` 插件 skill，插件提供通用 SDK/CLI/MCP 知识，项目 skill 负责 Genarrative 架构边界和验证门禁。

 - 现象：把 master（`9f5c84ee7`）合进 `feat/five_min_design` 后，`cargo check --all-targets` 在 Windows 上直接 `error[E0658]: use of unstable library feature 'windows_by_handle'`，位置是 `apps/ai-game-creator-shell/src-tauri/src/project/manifest.rs` 的 `metadata.number_of_links()`。该文件与 `origin/master` **逐字节相同**，即 master 自身在 Windows 上就构建不过。
-- 原因：`std::os::windows::fs::MetadataExt::number_of_links` 至今未稳定（rust-lang#63010），而 `rust-toolchain.toml` 锁的是 stable `1.96.0`。引入它的提交是 `578f8019f`（优化 AGC 项目入口并识别 Godot 工作区），其中 unix 分支用 `MetadataExt::nlink()`（已稳定）、windows 分支用了未稳定的对应物。**Linux CI 上 `#[cfg(windows)]` 整块不参与编译，所以 CI 全绿。**
+- 原因：`std::os::windows::fs::MetadataExt::number_of_links` 至今未稳定（rust-lang#63010）；当时 `rust-toolchain.toml` 锁的 stable 是 `1.96.0`，2026-09-20 升到 `1.98.1` 后在同一台 Windows 机器上用该 stable 实测仍报 `error[E0658]: use of unstable library feature 'windows_by_handle'`（见 decision-log 同日条），因此本条的处置口径不变。引入它的提交是 `578f8019f`（优化 AGC 项目入口并识别 Godot 工作区），其中 unix 分支用 `MetadataExt::nlink()`（已稳定）、windows 分支用了未稳定的对应物。**Linux CI 上 `#[cfg(windows)]` 整块不参与编译，所以 CI 全绿。**
 - 更普遍的形状：只要一段代码只在某个 `#[cfg(target_os)]` 下编译，它就完全绕过了其它平台的 CI——不只是 unstable feature，还包括类型错误、借用错误、缺失 import。跨平台分支是「双写」，两侧都得有人真的编译过。
 - 处理：本仓库对「文件是不是无硬链接普通文件」统一自行声明 `ByHandleFileInformation` 并调用 `GetFileInformationByHandle`，见 `runner/endpoint.rs`、`tool_plan_handoff/storage_windows.rs`、`project/agent_db.rs`、`git_inspect.rs`、`image_inspect.rs`、`agent/generation/canvas_generation.rs`。`manifest.rs` 当前已采用同一实现，并保留 fail-closed 语义：无法取得句柄信息或确认存在硬链接时均拒绝，同时拒绝 directory / reparse point。
 - 验证：改后 `cargo check --offline --all-targets` 通过、`cargo fmt --check` 通过、`project::manifest` 与 godot 相关定向测试 65 passed / 0 failed。判断「是不是本次合并引入」的通用手法：`git diff origin/master -- <file>` 为空即说明该文件就是 master 原样，问题不在合并。

 - 锁漂移边界：runtime 校验输出任一 `*_cache_lock=partial` 说明镜像内 lock 与当前 checkout 不同，不代表新增依赖已经缓存；必须同时输出 Actions warning，提示可信分支落地后刷新镜像。必须在新镜像中对 server-rs、桌面壳和 AI 游戏创作壳当前 lock 执行真实 `cargo fetch --locked --offline`；`cargo metadata --no-deps` 不会证明依赖 archive 可用，不能作为替代。
 - 构建网络边界：`CARGO_NET_RETRY` 只覆盖部分 crate 下载，registry `config.json` / index TLS 握手仍可能直接终止整次 fetch。Dockerfile 对每个 `cargo fetch --locked` 再做最多 5 次整命令级有界重试，最终仍执行断网 fetch，不能降低为无锁重试或省略离线闭合验证。

+- 构建参数 `AGC_UPDATE_CHANNEL` 默认 `dev`，支持 `release` 和自定义小写名称；名称符合 `[a-z][a-z0-9-]{0,31}`，不能以连字符结尾，不能为 `win/mac/windows/macos/darwin/linux` 或以 `-win/-mac` 结尾。构建目标独立决定系统和架构。
+- 为延续已发布客户端地址，OSS 继续使用 `agc/<channel>-win/` 和 `agc/<channel>-mac/` 作为物理分区；`dev-win/dev-mac` 是分区键，不是可填写的渠道。每个分区独立维护 `latest.json` 与版本目录，发布 release 不覆盖 dev。旧 `agc/latest.json` 迁移桥与其版本高水位仅属于 dev 的 Windows 分区。
+- 网站由服务端配置 `GENARRATIVE_CLIENT_DOWNLOAD_CHANNEL` 选择检测渠道，默认 `dev`；更改后重启 API 服务生效。`GET /api/client-downloads` 返回该渠道 Windows/macOS 的真实已发布版本。请求参数不能覆盖配置或指定 URL；配置非法时失败关闭，不悄悄改读 dev。
+- 同一渠道中不同系统仍可具有不同 release 版本；未发布的系统隐藏，单系统失败不影响另一系统。不会从其他渠道补齐缺失版本。
+- 验收必须覆盖 dev/release/自定义渠道各自端点和对象地址、独立版本、非法名称、旧 dev 地址延续、release 不写旧迁移桥、网站配置贯通、跨渠道链接拒绝和部分失败。
 - 更新链路的信任来源从「清单里的 sha256 + 受信域名」升级为「发布签名 + 受信域名」：清单里的 `signature` 由构建期私钥生成，客户端用内置公钥校验，校验不过就拒绝安装。

+- 应用退出（`RunEvent::Exit`）不重复发起同步；退出路径只负责在有界预算（15 秒）内等待在途同步收尾，让关窗触发的那一次同步有机会写完索引再退出。超过预算不能声明最后状态已经上传。
 - 客户端扫描、差异对比、索引持久化与上传编排都在 Tauri Rust 进程（`src-tauri/src/project_snapshot/`）；WebView 只读状态，不参与差异计算。
 - 本地索引是增量对比的唯一依据：`<AppData>/project-snapshots/<projectId>/index.json` 保存上次成功同步的相对路径、校验和、字节数和修改时间。项目根使用现有 manifest 的稳定 `project_id` 作为远端身份，路径不再作为身份。
 - 可观测性按产品口径收敛到本机日志：同步结果、失败分类、延后与跳过计数只写入 AppData 诊断日志（`project_snapshot.sync.*` 前缀），客户端界面不暴露上传状态、时间线或入口按钮。`read_local_project_snapshot_state` 与 `sync_local_project_snapshot` 两条命令仅作为 native-only 的排障与联调入口登记，不在渲染层调用。
 - 远端写入经 `api-server`，客户端只持平台登录态 Access Token。两条登录态路由：`POST /api/agc/project-snapshots/files`（单文件，正文为原始字节，元数据走查询串）与 `POST /api/agc/project-snapshots/manifest`（本次同步后的完整清单）。
 - 对象键与清单由服务端决定：文件键为 `agc/project-snapshots/v1/{userId}/{projectId}/files/{sizeBytes}-{checksumDigest}/{relPath}`，清单键为 `agc/project-snapshots/v1/{userId}/{projectId}/manifest.json`。键里带字节数与摘要，因此"对象已存在且长度一致"可以作为内容一致的判据；路径按原始大小写保留，不走 `put_object` 的低位规范化。`agc` 前缀继续是服务端专用私有前缀，通用对象键解析与客户端直传票据都不覆盖它。

 - 每次成功同步的最后一步上传该项目的 `manifest.json`（当前全量文件清单：相对路径、摘要、字节数、同步序号）。清单描述的是项目当前全量内容，因此清单体积就是该项目在 OSS 上的常驻占用。
 - 远端回收：清单写入成功后，服务端读取上一版清单，按 `(路径, 字节数, 摘要)` 反推出不再被当前清单引用的对象键并删除。只处理上一版清单登记过的键，不做 LIST，因此不可能误删其它项目或其它功能的对象；单次最多回收 2000 个对象，剩余部分留到下一次清单写入继续；上一版清单读不到或解析失败时整轮跳过回收（fail-closed）。单个删除失败只记日志，不影响本次同步语义。

+- 清单补充可选 `projectName` 与 `pendingFiles`：名称来自本地 manifest；`pendingFiles` 是本轮失败、延后、并发变动与非策略排除的跳过文件数量。`0` 表示扫描范围已同步；大文件等被跳过不能标成完整。旧清单字段缺失表示完整性未知，维持可读取兼容，不反写旧清单。
+- 项目名称或完整性发生变化时，即使文件内容没有差异也要提交新清单；本机索引记录上次已提交的这两个字段。实际客户端下一次正常同步可补齐历史清单元数据；后台只读访问不迁移旧清单。缺失 `pendingFiles` 不能默认成 0，临时跳过原因消失后允许无文件上传的 `partial → ready` 转换。
+- 后台增加“项目工程”入口，仅 owner 及拥有 `project-snapshots` 页签权限的管理员可访问。`GET /admin/api/project-snapshots?cursor=&limit=20` 读取私有 OSS 清单并返回 `{items,nextCursor}`；单页最多 100 个，游标由服务端校验，目录与清单读取有界。条目为 `{userId,projectId,projectName,syncRevision,syncedAtMs,fileCount,totalBytes,status}`，状态为 `ready / partial / unverified`，名称缺失时显示 projectId。
+- `GET /admin/api/project-snapshots/{userId}/{projectId}/download` 只读取该用户/项目的固定清单与其引用对象，返回 `application/zip` 附件。ZIP 中路径直接使用原始相对路径，不包含 userId、摘要目录或 OSS 前缀；名称使用经过安全处理的项目名和 revision。下载固定本次读到的清单，远端并发回收导致对象缺失则整体失败，不能静默遗漏。
+- `partial` 快照下载返回 409；`unverified` 历史快照可导出已同步文件，列表明确显示“完整性未知”，动作称“下载已存文件”。`ready` 才显示“下载完整工程”。ZIP 构建核验每一文件的长度与 fnv1a64 摘要，拒绝穿越、绝对路径、重复/大小写冲突路径、非法项目身份；缺失或损坏整体失败，不返回成功的残缺 ZIP。
+- ZIP 使用服务端临时文件并限制并发，不将 2 GiB 工程整体驻留内存；成功、失败、客户端取消均清理临时文件。单文件、总量、文件数沿用上传上限，超限明确拒绝。零字节工程文件可以上传和导出。OSS 凭据与签名不下发浏览器，列表失败保留错误而非伪造空列表。
+- 工程归档范围与上传策略一致：源码、素材及引擎配置按原路径保存，依赖/构建缓存、凭据、`.agent` 会话与运行日志排除；此 ZIP 不声明能恢复 AGC 对话历史。后台读取需要目标前缀的 ListObjects 与 GetObject 权限，不新增数据库表，不改 External API。
+- 验收覆盖真实单窗口生命周期登记、首次/增量/零字节上传、后台列表分页和权限、ZIP 解压目录及摘要、部分/历史清单、缺失对象、路径拒绝、下载取消清理，并分别报告定向测试和真实环境证据。

 ### 未决问题
 
 - 用户侧看不到同步状态与失败原因（界面按产品口径不暴露），排障只能读 AppData 诊断日志或调用 native-only 命令；如果后续要支持用户自助排查，需要先确认是否允许在客户端出现上传相关 UI。

 ## 执行风格
 
-- 修改范围保持聚焦，不做无关重构。
+- 修改范围围绕交付结果与验收判据保持聚焦。
+- Agent 可见内容直接描述当前任务、输入和成功条件，细节按调用需要提供。
 - 跨模块、公开契约、SpacetimeDB schema、AGC/Runtime 和复杂 UI 状态链路按 [`docs/【协作规范】规范驱动开发工作流-2026-09-12.md`](./【协作规范】规范驱动开发工作流-2026-09-12.md) 执行主规范、里程碑、实现计划和逐里程碑验收；局部修复继续使用轻量流程。
 - 优先复用现有系统、页面、组件、脚本、DTO 和文档位置。
-- 不新增平行入口、平行作品架、平行公开列表、平行业务真相或临时兼容层。
-- 不把前端临时状态当正式业务事实；正式状态以后端投影、后端 API 或当前架构文档为准。
-- 涉及中文内容时保持中文，不擅自翻译成英文。
-- 发现中文乱码时先确认真实编码，不直接沿用乱码，也不用英文替换。
-- 含中文文件优先局部补丁；非必要不要整文件重写。
+- 正式状态以后端投影、后端 API 或当前架构文档为准。
+- 涉及中文内容时保持中文；发现乱码时先确认真实编码并恢复正确中文。
+- 含中文文件优先局部补丁。
 - 阶段性大任务完成后，整理当前上下文、剩余风险和下一步入口，降低后续接手噪音。
 
 ## 文档规则
 
 - 工程修改必须同步更新对应 `docs/` 文档。
 - 没有合适文档时，新文档放入 `docs/` 下合适位置，文件名使用 `【标签名】中文标题-日期.md`。
-- PRD 或技术方案要具体到能指导编码，不写会导致落地漂移的泛泛描述。
+- PRD 或技术方案要具体到能指导字段、契约、状态和验收的实现。
 - 长期有效的架构约定、接口变化、排障经验、开发流程或协作规则写入 `docs/project-memory/shared-memory/`。
 - 阶段性计划放入 `docs/project-memory/plans/`；确定但未实施的共享 TODO 放入 `docs/project-memory/todos/`。
 - 不提交个人配置、密钥、Token、Cookie、会话记录、认证文件、本地私密路径、构建产物、日志、缓存和数据库 dump。
 
 ## UI 与前端规则
 
-- UI 面板保持清爽，不默认写功能说明、规则说明、键盘快捷键说明或开发解释文本。
+- UI 面板优先呈现任务内容与操作，说明按当前操作需要提供。
 - 移动端优先，同时保证桌面端体验完整。
-- 弹出独立面板的交互使用弹窗、抽屉、popover 或页面级 portal，不在当前面板下面追加内容。
-- 页面展示以后端返回状态为准，不在前端自行计算结论型业务状态。
-- 现役平台入口固定为 `/creation`、`/project`、`/profile`：创作主页只读取图片编辑器项目与公开编辑器素材，个人页只复用账号、钱包和公共设置能力。旧 `/api/creation-entry/config` 及模板工作台、公开作品和专属运行态已经退役，不得因历史表仍在而恢复前端入口或后端接口。
-- 优先扩展现有公共组件，例如平台弹窗、图片输入、媒体预览、状态提示和动作按钮，不在业务页复制通用逻辑。

 ## 后端与数据真相
 
 - 后端路线固定为 `server-rs + Axum + SpacetimeDB`。
-- 旧 `server-node`、Express、PostgreSQL、Go 服务端、`maincloud` 相关脚本、环境变量、测试和文档要求均为历史残留。
 - 领域规则沉到 `module-*`；SpacetimeDB 表、reducer、procedure、事务 adapter 和 row mapper 留在 `spacetime-module`。
 - 后端访问 SpacetimeDB 统一经 `spacetime-client` facade。
 - HTTP / SSE / BFF 和外部副作用编排留在 `api-server`；OSS、LLM、认证、语音等外部平台能力留在 `platform-*`。
-- 前后端 DTO、公开契约和跨页面复用的无业务真相 TypeScript 代码留在 `shared-contracts` / `packages/shared`；共享 UI 组件与纯工具可留在 `packages/shared`，但领域规则、后端副作用和正式状态不得下沉。
+- 前后端 DTO、公开契约留在 `shared-contracts` / `packages/shared`；共享 UI 组件与纯工具留在 `packages/shared`，领域规则、后端副作用和正式状态由后端对应层负责。
 - 契约、路由、DTO 去留和 breaking change 以当前后端架构文档、`api-server/src/app.rs`、`shared-contracts` 和 `packages/shared` 为准。
 
-后端修改后按当前 DDD 文档执行验收。涉及 API smoke 时，使用 `npm run dev:api-server` 重新拉起后端并检查 `/healthz`；不要使用旧 `maincloud` 启动口径。

+
+列表按清单中的 `pendingFiles` 区分 `ready / partial / unverified`；历史字段缺失必须为 `unverified`。下载冻结本次清单，按原始目录构造 ZIP；逐项核对长度和摘要，部分同步、对象缺失、损坏或危险路径不能返回完整工程。客户端不接触 OSS 凭据。完整契约见 [AGC 实施计划](./technical/【技术方案】AI游戏创作智能体App实施计划-2026-06-24.md) 的“后台工程列表与下载”。
+
 路由树由 `server-rs/crates/api-server/src/app.rs` 统一构造。当前主要分组：
 
 - 健康检查：`GET /healthz`、`GET /readyz`。
 - 后台管理：`/admin/api/*`，现役路由包括登录与账号管理、Dashboard / 概览、HTTP debug、埋点、表查询、通用 feature gate、编辑器定价与素材 / 精选管理，以及账号侧兑换码、邀请码、任务、钱包、充值与退款管理；不再挂载旧创作入口配置、旧作品互动或旧玩法运营路由。环境变量管理员固定作为 owner，持久化 member 每次请求按当前 `enabled`、`token_version` 和一级 Tab 权限实时校验；账号管理仅 owner 可访问，未登记权限映射的新后台路由对 member 默认拒绝。完整权限矩阵见 [`docs/technical/【后台管理】多账号与Tab访问权限方案-2026-07-14.md`](./technical/【后台管理】多账号与Tab访问权限方案-2026-07-14.md)，Dashboard 指标口径见 [`docs/technical/【后台管理】Dashboard运营看板方案-2026-06-23.md`](./technical/【后台管理】Dashboard运营看板方案-2026-06-23.md)。
 - 通用灰度控制面固定为后台 `#gray-release` 与 `GET/PUT /admin/api/feature-gates`；页面固定目标只登记现役功能，不读取旧 `/admin/api/creation-entry/config`，也不恢复 `creation-entry:*` 动态目标。
+- AGC 模板库使用 `agc:template-library`，不新增 schema；`GET /api/runtime/frontend-config` 追加账号相关的 `agcTemplateLibraryEnabled`，匿名和 Gate 缺失为 false，存在配置时复用通用灰度规则。响应设置 `Cache-Control: no-store` 与 `Vary: Authorization`，客户端原生操作独立检查权限。官网公开 `GET /api/client-downloads` 则读取服务端 `GENARRATIVE_CLIENT_DOWNLOAD_CHANNEL`（默认 dev）对应的 Windows/macOS 分区，渠道与系统独立，不从请求 query 接受 URL 或渠道覆盖。
 - 认证与账号：`/api/auth/*`、`/api/profile/me`，包括短信、密码、微信、refresh session、多端会话和登出。
 - 个人中心：`/api/profile/*`，包括钱包流水、任务、领奖、充值、反馈、邀请和兑换等账号侧能力。
 - 平台基础能力：`/api/llm/*`、`/api/speech/volcengine/*`，只保留通用 LLM 和语音代理。

 - 每个用户回合必须由 LLM 返回结构化计划；单次 completion 不是有效 JSON 时，runner 先把无效原文作为 assistant message 追加到当前 staged turn，再追加 system 纠正消息，明确要求下一轮只按既定 JSON Response Format 重试；下一次 completion 必须同时看到该无效原文和纠正指令。无效原文只是重试上下文，不进入对外 `PromptOutput` 或用户可见的会话增量；后续规划成功时随 staged turn 一并提交，无工具活动且最终失败时按下文事务规则整体回滚。LLM 未配置、连接已经断开、请求明确失败、达到最终安全上限或多轮重试后仍不可解析时，后端写入正文为 `ERROR <错误内容>` 的 system 消息，不使用本地关键词或“收到：...”回显兜底。面向用户的规划错误使用中文语义，不暴露 `completion error` 等 framework 内部前缀或原始配置/定价诊断；原始错误只记录在后端日志。该错误消息与其它 system 消息一样进入后续 LLM memory，使 Agent 能看到上一轮失败上下文。普通 JSON POST 尚未结束只表示 provider request future 仍在等待，不能伪装成已持久化失败。
 - 工具参数中的图片 ID 是由真实 object key 或图片地址计算的稳定 SHA-256 标识；真实 data key 仅存于 api-server 的工具上下文映射，所有图片工具在执行时查表恢复，不能把 object key 或图片地址作为 LLM 可见的工具 ID。
 - 规划 prompt 必须显式区分“规范展板”和“实际素材产出”：规范图、视觉规范图、风格规范图、素材规范展板、角色规范图等规范展板请求走 `generate-image`，并补齐统一视角、线条粗细、色卡、材质、阴影、圆角、状态层级、尺寸标注等要求；实际角色立绘才走 `generate-character`，多个图标素材 / 图集才走 `generate-icon-spritesheet`。
-- 用户的当前消息确实在确认或取消一条已存在且仍为 pending 的工具调用时，画布 Agent 只引导使用该卡片的确认 / 取消按钮，本条确认 / 取消意图不产生新 tool call。这条边界必须使用“匹配 pending 调用时如何处理”的正向、条件化描述，不得改写成“不得重新发起相同工具调用”一类全局否定话术：实测中模型会把这类否定句过度泛化为拒绝后续新请求。已 cancelled 的卡片不再处理；用户明确要求修改、重做或发起新任务时必须允许新 tool call，pending 卡片也不阻塞无关的新请求。
+- 用户通过当前消息确认或取消已有工具调用时，Agent 先读取历史状态：pending 调用引导使用对应卡片的确认 / 取消按钮；cancelled 调用视为已结束。用户明确要求修改、重做或发起新任务时提交新 tool call。独立调用可并列存在，并在一次回答的 `tool_calls[]` 中尽量批量提交。图片 ID 从用户引用或历史工具结果的 system message 获取；上下文确实缺少对应图片时，请用户重新引用图片。
 - 画布 Agent 规划请求使用 Chat Completions 和 1024 生成 token 预算；VectorEngine 专用 client 发送 `max_completion_tokens`，预算包含可见输出与隐藏 reasoning token，不等于可见正文长度。发送后 120 秒是前端软提示阈值，不是 provider 失败 deadline：若普通 JSON POST 仍 pending，消息流临时显示“仍在处理中，请耐心等待”并继续等待，提示不写入 OSS 消息历史；连接或请求明确失败则立即按正式错误收口。provider 单 attempt 保留 8 分钟 hard timeout；请求发起阶段的 timeout、连接失败、`408`、`429` 与 `5xx` 读取 `GENARRATIVE_LLM_MAX_RETRIES`，但画布 Agent 最多重试 1 次，专用重试退避最多 60 秒。消息规划生命周期从 handler 入口开始计入 18 分钟总 deadline，进入 `agent.prompt(...)` 时使用扣除会话锁和上下文准备后的剩余预算；该 deadline 必须作为 runner 内部 deadline future 参与 completion await，并在每个 tool 开始前、返回后检查，不能用外层 `tokio::timeout` 丢弃整个 prompt future，也不能中途 drop 已开始的工具。工具一旦开始就等待其返回，再按 deadline 携带结果收口；当前八类画布工具只做同步参数校验并返回待确认，因此不会延长正式生成链。deadline 命中时仍按 `PromptRunError` 返回已经完成的工具结果、提交对应 staged memory 并追加终态错误。该 deadline 覆盖非法 JSON/工具校验失败触发的后续规划轮，并为错误持久化和 HTTP 返回保留约 2 分钟，不再让前端 20 分钟 transport timeout 先触发。已收到成功响应头后的响应体读取或解析失败直接按明确失败收口，错误计数/日志使用该响应所属的真实 attempt。规划重试发生在任何生成工具执行之前，不会重复提交生成任务或扣费；生成图片/编辑图片仍走对应生成工具和模型计费。
 - function-calling runner 必须把“等待用户确认”作为显式工具语义：当本批所有工具都校验成功并进入待确认状态时，立即以成功结果结束当前规划回合并持久化助手文本与待确认卡，不得继续依赖 LLM 自行停止；未知工具、参数错误、普通连续工具和不可解析响应仍受 `max_turns` 保护。
 - runner 失败必须返回显式的 `PromptRunError { error, partial_outputs }`，不得只返回终态错误而丢弃本轮已产生的文本或工具事实。prompt 执行使用 `AgentMemory::begin_staged` 创建行为等价且写入隔离的 `StagedAgentMemory` 事务，限长、摘要、脱敏等 append 规则必须在本轮 completion 前生效；成功或已发生工具活动时必须显式调用 `commit()`，直接 drop staged transaction 表示回滚，不得统一复制成 `VecMemory` 或仅替换 box 冒充持久化提交。本轮无工具活动失败时回滚 staged 用户消息、助手文本和不可解析响应；已有工具活动时在末尾追加 terminal error closure 后提交。外部 drop / abort 若尚无工具活动则回滚并保持原 committed memory；若工具已完成则提交结果与取消闭环，若工具仍在执行则提交“已启动、结果未知”事实与取消闭环，后续必须先 reconcile 再决定是否重试。
 - `ToolFailure` 必须以结构化工具失败输出暴露给 harness 调用方：调用方能读取 `kind`、`retryable`、`fatal` 和工具返回的原始 `output`；不得把它们压成单一错误字符串。这些字段只提供流程决策与诊断事实，是否重试、如何展示或持久化仍由业务调用方决定。
 - api-server 收到带 `partial_outputs` 的终态失败时，必须先按原顺序把其中已成功工具转成 `status=not_completed` 待确认消息并写入同一会话增量，再追加 `ERROR <错误内容>` 终态 system 消息；不得因后续轮次、其它工具或 `max_turns` 失败而吞掉已经执行并返回的工具结果。
-- 通用 JSON function-calling 协议、工具 schema 注入、memory / hook、`max_turns` 和“全部工具待确认即结束回合”统一由现役 `platform-agent-harness` 承载；无工具时也必须输出同一 JSON 响应格式。画布角色 prompt、规范展板 / 已有图路由、模型与超时 profile、八类工具、计费、OSS 会话和 external job 编排继续留在 `platform-editor-agent` / `api-server`，不得回流已退役的旧 `platform-agent`。
+- 通用 JSON function-calling 协议、工具 schema 注入、memory / hook、`max_turns` 和“全部工具待确认即结束回合”统一由 `platform-agent-harness` 承载；纯文本回复使用相同 JSON 格式并设置 `tool_calls: []`，独立工具调用在同一批次提交并顺序执行。画布角色 prompt、规范展板 / 已有图路由、模型与超时 profile、八类工具、计费、OSS 会话和 external job 编排由 `platform-editor-agent` / `api-server` 承载。
+- 画布角色提示词、共享路由规则、工具与参数说明维护在 `server-rs/crates/platform-editor-agent/prompts/`；通用 JSON function-calling 提示词、工具条目模板与纠正消息维护在 `server-rs/crates/platform-agent-harness/prompts/`。Rust 使用 `include_str!` 编译包含正文，负责变量填充、schema 结构和执行校验。
 - **对话回合免费**（聊天、分析回复不扣泥点），仅 Agent 实际触发生成工具时按对应模型定价扣泥点。
 - 工具调用前后端校验泥点余额；不足时该次生成失败并在对话中以明确错误气泡告知，对话本身可继续。

+- 用户通过对话确认或取消已有调用时，先读取历史状态：pending confirmation 状态引导用户使用确认/取消按钮；cancelled 状态已结束，用户明确提出修改需求时发起新工具调用。其他待确认或执行中的调用允许并列存在，独立的新需求可继续提交。
+- 按各工具的单次产出数量拆分调用，在一次回答的 tool_calls[] 中尽量批量提交所有无依赖的工具调用。prompt 填写单次产物的生成要求。
+- 图片工具参数使用 image_id（形如 sha256:*）。从用户上传/引用前的 system message，或历史工具结果的 system message 中取得真实 ID；根据当前指代选择对应图片并直接调用。
+- image_id 仅用于工具参数。上下文中确实找不到用户所指图片时，说明缺少图片引用并请求用户重新引用图片。

-你是 Genarrative 图片画布 Agent，只负责帮助用户理解、规划和触发画布生成工具。对话回复要简短.
-我们的工作是这样的：
-- 我们提供的和外界交互的工具有一些是付费的, 需要用户二次确认,
-  这种在消息历史里会显示这类工具调用的状态(pending confirmation/completed/cancelled), 用户决定取消与否由用户界面工具消息的确认/取消按钮决定,决定后会在历史消息里更新.
-  如果用户试图以对话的方式来确认/取消 一个已经发起的 付费/风险工具调用(注意不要拒绝发起新的),并且那条工具调用确实处于pending状态(这一点你要从历史消息里自行确认,禁止向用户询问)你应该引导他使用确认/取消按钮
-  对于已经被用户取消的工具调用是无法再次被确认的, 不要要求用户处理.这说明有的地方做的不对, 如果用户明确要修改, 请发起新工具调用.
-  一个等待确认的工具调用不影响另一个工具调用的发起, 不要因为尚未确认或完成就拒绝发起另一个.
-  工具调用本身存在二次确认, 用户会自行判断或者要求更改.请直接发起工具调用请求,禁止在对话中dump参数(包括隐式推断的引用参数)并要求确认.
-- 一些工具一次调用只能产出一个结果, prompt只是调用其他生成式模型的原始参数,不会被解释执行.(比如prompt里要求生成多少个是无效的),但是可以通过多次(尽量批量)地调用.
-- 在一次回答中完成尽可能多的任务: 在一次回答的tool_calls[]中就发起尽可能多(无依赖)的工具调用, 而不是利用多次回答,每次只一个来完成.
-- 我们使用 image_id(形如 sha256:* 的字符串)来引用任意图片(规范图/生成的/用户引用的/...)作为工具参数.
-- 用户不知道也不应该知道image_id的存在, 你不应该也不可能向用户索要.
-- 用户提供给你的image_id可以有这些来源:
-  1.显式上传/引用:以system message的形式在用户指令前为你准备好, 显然这些一定会用到,不然引用它(们)干什么
-  2.隐式推断:用户并没有引用/上传,指令中却有所指代,那么就是过去引用/上传的图片或者工具生成的图片(出现在工具调用结果的system message中, 尤其有可能是上一次工具调用生成的产物),... 需要你自行推断并且使用, 禁止劳烦用户重新引用/上传, 禁止在对话里要求确认
-- 我们的滑动窗口上下文有限, 如果你确实无法找到用户的指代(可能被历史截断了), 请说明情况请求用户重新引用(但不是告诉你image_id)
