合并 origin/master（真合并：AGC 统一错误诊断 / 图集连通域切分）

- canvas_generation.rs：接入 master 新增的 slice_mode / grid_x / grid_y 结构体字段 - commands.rs：master 的 read_agent_runtime_error_detail 命令与本分支 read_direct_tool_calls 并存（两侧都保留） - main.rs：两条命令都注册 - 冲突按"两侧语义都保住"处理；未跑测试

 - Use stable references such as `objectKey`, project resource ID, or asset ID where each operation permits them. Image edit/redraw is stricter: `sourceReferenceId` accepts only a registered project resource ID or asset ID; upload confirmation alone is not enough. Use `/assets/read-url` only for temporary preview/download access.
 - Preserve both warning channels after completion. A general `warning` can coexist with `sliceWarning`; do not discard either.
 - Do not invent missing derivatives. A source-preserved warning means the main source remains usable but requested post-processing failed. A slice warning means the complete transparent sheet is usable but individual slices are absent.
+- Icon spritesheet generation accepts `sliceMode="connected-components"` (default alpha-connectivity detection) or `sliceMode="grid"`. Grid mode requires `gridX` and `gridY` (1-32); use `sliceCount` only to constrain connected-component output.
 - For successful `style="pixelArt"`, treat completed-result and nested resource/asset dimensions as the final logical-grid PNG dimensions. They may differ from `size`, `imageSize`, the provider image, and `canvasCompletion.placeholder`; do not rescale or reject the artifact to match those inputs.
 - Keep generated artifacts in the canvas and asset library together. Character animation accepts `assetFolderId` and `assetLabel`; its completed result directly returns the final `assetKind="character-animation"` resource and asset with formal sequence fields. Do not create a duplicate first-frame record.

 The icon-spritesheet primary `referenceId` is intentionally stricter than ordinary image references: it accepts only a current-owner project resource ID or asset ID whose authoritative `assetKind` is `icon-spec`. It does not accept an `objectKey`, URL, Data URL, or Blob URL.

-`sliceLayout: "grid-2x2"` is an opt-in contract for four fixed game-runtime assets. The provider prompt and server persistence both preserve the ordered slots left-top, right-top, left-bottom, right-bottom.

+`sliceMode` controls atlas splitting. Use `"connected-components"` (default) to detect independent opaque regions by alpha connectivity, or `"grid"` with positive `gridX` and `gridY` values (maximum 32 each). `sliceCount` optionally constrains the connected-component result.

 ## Authorization boundary

 `agc_tools` is an AGC client-owned bridge to the AGC backend. In the normal client build it uses the current client login session and account routes; the user and model never need to provide, configure, paste, create, or rotate an API Key, Token, Cookie, URL, or `.env` value. If the tool returns `401` or `403`, report only that the AGC client login or permission state is unavailable, stop the operation, and do not ask the user for credentials or expose an internal URL.

+- For direct `agc_generate_image` spritesheet requests, `sliceMode="connected-components"` selects alpha-connectivity detection and `sliceMode="grid"` uses the caller-provided `gridX` and `gridY` (1-32 each).

 - 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.
 - `resources` contains only safe registered identity fields: local asset/path/kind/media type, Canvas project/resource/asset/task IDs, and reference resource IDs. It never exposes prompts, models, provider routes, absolute paths, URLs, tokens, cookies, or API keys.

+Parent Milestone: `【里程碑】AGC统一错误诊断与验收反馈-2026-09-15.md`
+
+## 修改边界
+
+1. 新增 `agent/runtime_error.rs`，承载统一事件字段、code/stage 白名单、脱敏后的 public projection、项目错误 JSONL/sidecar 落库和 detail 读取边界。
+2. `direct_runtime.rs` 使用统一事件替代仅写 `failure.json` 的路径；失败 assistant 投影带稳定 ID，下一轮 prompt 注入最近失败事件摘要。
+3. `codex_app_server.rs` 将 failed turn、idle/hard timeout、transport close、invalid terminal 和 stderr tail 转成稳定事件字段；不公开原始 detail。
+4. `direct_tool_bridge.rs` 与 `direct_tools_mcp.rs` 让 attempt 由客户端回合状态约束，越界请求返回终态工具错误；不扩展重试预算。
+5. `direct_runtime.rs` 的素材扫描递归覆盖可执行源码模块，基于 manifest 身份和浏览器 URL 映射判定；补充模块引用回归测试。
+6. 前端读取后端 `publicText/detailRef`，在现有 Runtime 错误面板中加入详情入口；不在 React 侧重新分类错误。
+
+## 实现顺序
+
+先写统一事件模型和 Rust 单测，再接 direct failure/app-server/tool bridge，随后接 prompt/history 与前端详情，最后修素材验收和 attempt 生命周期。每一步保留原有脱敏和失败关闭行为。
+
+## 验证命令
+
+- `cargo fmt --check`
+- `cargo test --manifest-path apps/ai-game-creator-shell/src-tauri/Cargo.toml runtime_error direct_runtime codex_app_server direct_tool_bridge`
+- `npm run --prefix apps/ai-game-creator-shell typecheck`
+- `npm run check:encoding`
+- `git diff --check`
+- 必要时运行 AGC deterministic playable E2E；真实 Provider smoke 与浏览器双视口 smoke 单独报告。
+
+## 风险与回滚
+
+- 统一事件 schema 只新增项目内文件和对话投影，不修改已有 manifest、公开 API 或 SpacetimeDB schema。
+- 若前端详情读取失败，仍展示安全 `publicText`，不阻塞错误终态。
+- 若素材身份无法映射，继续失败关闭并记录明确 code，不回退为路径字符串通过。
+- 回滚可删除新事件写入和详情入口，保留旧 `failure.json` 读取兼容。

+
+## 目标
+
+让 DirectProject 和共享 Agent Runtime 对失败使用同一份安全、可追踪、可恢复的错误事件合同；用户追问失败原因时能够读取上一轮证据；构建与浏览器验收只依据真实源码、manifest 身份和运行时证据判断。
+
+## 范围
+
+- 统一错误事件模型与项目内诊断落库。
+- DirectProject 失败 assistant 投影、下一轮诊断上下文和前端详情入口。
+- app-server 终态/超时、内置 MCP 工具错误和试玩 attempt 上限的分类。
+- 游戏源码模块素材扫描、manifest 身份映射与浏览器观察映射。
+- 定向 Rust/前端回归和现有 AGC 运行时门禁。
+
+## 不做
+
+- 不改变 Provider、External Editor 或 app-server 的 wire 协议。
+- 不放宽项目写锁、凭据隔离、工具白名单或完成门安全边界。
+- 不迁移历史项目文件；旧诊断只读兼容，新增事件使用新 schema。
+- 不把原始 stderr、请求正文或绝对路径展示给用户。
+
+## 验收标准
+
+1. 任一 DirectProject 失败均生成统一事件、稳定 `eventId` 和有界诊断引用；落库失败不覆盖原始错误。
+2. 失败安全投影写入对话历史，下一轮能读取 `publicText / code / stage / detailRef`，不会因追问而自动试玩。
+3. 结构化 failed turn、idle/hard timeout、transport close、MCP 参数错误和 `other` 各有稳定 code 与 recoveryHint。
+4. `attempt` 由客户端按回合分配并有上限；越界调用不会让回合继续等待。
+5. `game/src` 下模块引用已登记素材、Vite dist 稳定映射和浏览器实际观察均能通过；未登记素材仍失败。
+6. 脱敏测试证明 Token、Cookie、URL/query、私钥、宿主绝对路径和 stderr 私密内容不会进入用户文本。

 - 图标 spritesheet 的入队与实际执行路径都必须在引用解析、generation input 重建、定价和 provider / OSS 副作用之前预检 owner、项目和最终素材目录，并将返回的 canonical `projectId + assetFolderId` 回写到后续流程；请求省略目录时按实际写入的 owner 默认目录预检，worker 不得只信任入队时的旧校验结果。
 - queued 图标规范生成由共享原子结果持久化使用 worker caller 中的 lease 一并完成任务并清理 lease；共享执行器返回成功后 worker 只能返回 `Ok(())`，不得再次调用 job completion。
