 # Milestones
 
+## v1.0 v1.0 (Shipped: 2026-04-17)
+
+**Phases completed:** 8 phases, 13 plans, 14 tasks
+
+**Key accomplishments:**
+
+- 交付了可复现冲突证据链、文件级风险清单与 Titan 重叠决策矩阵，形成“旧视觉+新逻辑”执行输入。
+- 线程路由从 isnew 参数切换为路由单路径语义，并将 skills bootstrap 合同统一到 content_ids。
+- 完成 03-UAT 的关键 gap 收敛：lint 阻塞清零，welcome-and-routing 从 4 失败收敛到 0 失败。
+- 基于 originui 合并基线完成 Phase 3 执行记录，并输出可审计的视觉与回归验证结果。
+- 完成 Phase 4 首轮执行：iframe 通信与导出链路加入前端容错，目标 lint/E2E 验证通过。
+- Phase 5 执行完成：目标 E2E 套件达到“0 失败、可解释 skip”，并形成提交卫生分组建议。
+- 完成引用提交契约与软失败链路，确保 uploads + references 统一进 `additional_kwargs.files`。
+- 完成输入框 `@` 引用交互闭环：候选展示、过滤、选择、chip 渲染、删除、键盘操作与上限控制。
+- 补齐 Phase 6 的验证与提交卫生材料，并记录了可复现的 E2E 环境阻塞证据。
+- 输入框 `@` 引用链路已收口：候选贴边定位、内嵌引用预览与 6 个上限、artifact 引用可转为上下文可消费的 uploads 契约。
+- Phase 06 最后一个 gap-closure 计划已收口：输入框引用合同重新对齐 requirement=10，DF-INPUT-008/009 都已变成可重复运行的稳定回归。
+- Phase 06 的执行文档已闭环，提交顺序与验证证据可直接供后续 verify-work 与审阅使用。
+- Phase 06 已完成 `@` 文件引用能力（artifacts + uploads）及提交契约收敛，并具备可审计验证材料。

+
+### FAIL Gate
+
+`gaps_found` is enforced because unsatisfied requirements exist (11), including orphaned requirements assigned in traceability but absent from all phase VERIFICATION files.
+
+## Integration Checker Results
+
+### Critical
+- No critical integration break found across phases 2 to 7.
+
+### Non-Critical
+- LOGIC-03 compatibility gap (`xclaw_used` path not evidenced in runtime).
+- LOGIC-04 compatibility risk (legacy adapter evidence incomplete).
+- Phase 2 summary/code artifact drift.
+- Phase 7 has validation but no verification artifact.
+
+## Broken Flows
+
+- Legacy compatibility flow (`thread_id/isnew/xclaw_used`) breaks at xclaw_used ingestion/propagation.
+- Verification evidence flow breaks at missing phase-level VERIFICATION artifacts.
+
+## Overall Conclusion
+
+Milestone `v1.0` is **not ready to complete** under current audit gates. Requirements and integration implementation are substantial, but verification artifacts are incomplete for multiple phases, causing orphaned requirements and mandatory `gaps_found` status.

+# Phase 07 Plan 01 Summary
+
+实现了“提交态增强文本 / 显示态原文”的完整链路：发送时自动拼接附件与 Skill 优先提示，消息区仍只展示用户输入内容。
+
+## Implemented
+
+- 新增 `priority-hint` 纯函数模块，封装 `buildPriorityHintText` 与 `composeSubmitText`。
+- `InputBox` 在提交时统一透传 `references + selectedSkills`，覆盖按钮发送、回车发送、建议词发送路径。
+- `useThreadStream` 与 `useSubmitThread` 在调用 `thread.submit` 前组装 `submitText`。
+- `message-list-item` 渲染人类消息时增加固定后缀剥离，避免回显“优先使用【...】”。
+
+## Verification
+
+- `node --test frontend/src/core/threads/hooks.test.ts`：7 passed
+- `cd frontend && pnpm -s typecheck`：passed
+- `cd frontend && pnpm -s test:e2e --grep "DF-INPUT-008A"`：passed
+
+## Notes
+
+- 本次新增 e2e 用例验证“请求体包含拼接文案，消息区不显示拼接文案”的核心回归场景。

+# Phase 07 Plan 02 Summary
+
+完成了 Phase 07 的 3 个 UAT gap closure：引用误触发、提示前缀唯一化、Skill 提示标识稳定化。
+
+## Implemented
+
+- 将 artifact 列表与消息附件中的 `ContextMenuItem` 引用动作从 `onSelect` 改为 `onClick`，避免仅右键打开菜单就自动引用。
+- `priority-hint` 规则升级为 `XClaw优先使用...`，并保持“附件在前、Skill 在后、大小写不敏感去重”。
+- `stripPriorityHintSuffix` 同步匹配新前缀，确保消息区继续只展示用户原文。
+- `hooks.ts` 在两条发送链路中均改为使用 `selectedSkills.skill_id` 参与提交态拼接。
+- 单测与 E2E 断言同步更新到新前缀。
+
+## Verification

+- `cd frontend && pnpm -s typecheck`：passed
+- `cd frontend && pnpm -s test:e2e --grep "DF-INPUT-008A|reference|context menu"`：1 passed
+
+## Notes

+# Phase 7: 发送时拼接附件与Skill优先提示词并在消息区过滤 - Context

+**Gathered:** 2026-04-17
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+在用户发送消息时，将“附件/引用文件 + 已选 Skill”转换为一段附加指令并拼接到提交给后端的提示词中；同时保证消息区仍只展示用户原始输入，不展示这段拼接指令。
+
+本阶段不新增新的消息协议主结构，不改变现有 `additional_kwargs.files` 的来源语义，只在发送链路中补充“提交态提示词增强”。
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### 拼接文案规则
+- **D-01:** 统一使用格式：`优先使用【附件1、附件2】和【Skill1、Skill2】`。
+- **D-02:** 仅存在一类时只输出该类（仅附件或仅 Skill），两类都为空时不拼接。
+- **D-03:** 名称去重后再拼接，顺序固定为“附件 → Skill”。
+
+### 拼接时机与作用域
+- **D-04:** 仅在真正提交到后端前拼接，不改输入框内文本。
+- **D-05:** 覆盖所有发送入口：发送按钮、回车发送、建议词自动发送。
+
+### 消息区过滤策略
+- **D-06:** 采用“提交态增强、展示态原文”策略：
+  UI 和消息区始终使用用户原文；仅请求 payload 使用“原文 + 拼接文案”。
+- **D-07:** 不采用渲染层二次过滤（避免把拼接后文本写入消息主内容）。
+
+### 数据来源与去重口径
+- **D-08:** 附件名使用最终提交文件名（`references + uploads` 汇总后的文件名）。
+- **D-09:** Skill 名使用当前选中 Skill tag 的 `title`。
+- **D-10:** 去重采用大小写不敏感规则。
+
+### the agent's Discretion
+- 拼接文案中附件与 Skill 的最大展示数量（若过长时是否截断与“等N项”策略）。
+- “名称标准化”细节（如首尾空白裁剪、重复空格折叠）。
+- 内部 helper 命名与模块拆分方式（前提是不改变已锁定行为）。
+
+</decisions>
+
+<canonical_refs>
+## Canonical References
+
+**Downstream agents MUST read these before planning or implementing.**
+
+### 阶段边界与既有决策
+- `.planning/ROADMAP.md` — Phase 7 条目与边界（发送时拼接 + 消息区不显示）。
+- `.planning/STATE.md` — 当前里程碑状态与 Phase 7 演进记录。
+- `.planning/PROJECT.md` — 核心原则：保持现有体验并稳定新系统行为。
+- `.planning/REQUIREMENTS.md` — 现有约束基线（特别是稳定性与回归要求）。
+- `.planning/phases/06-/06-CONTEXT.md` — Phase 6 已锁定的文件引用/提交语义（`additional_kwargs.files`）。
+
+### 发送链路与输入框集成点
+- `frontend/src/components/workspace/input-box.tsx` — 输入框提交入口（`handleSubmit`）与 references/selectedSkills 来源。
+- `frontend/src/app/workspace/chats/[thread_id]/page.tsx` — 页面级 `handleSubmit` 到 `sendMessage` 的调用边界。
+- `frontend/src/core/threads/hooks.ts` — 实际提交到线程流的发送逻辑（payload 组装主入口）。
+- `frontend/src/components/ai-elements/prompt-input.tsx` — `PromptInputMessage` 结构与表单提交机制。
+
+### 消息展示与文件渲染链路
+- `frontend/src/components/workspace/messages/message-list-item.tsx` — 人类消息展示内容与附件列表渲染逻辑。
+- `frontend/src/core/threads/submit-files.ts` — references/uploads 汇总为 `additional_kwargs.files` 的归一化逻辑。
+
+</canonical_refs>
+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- `InputBox.handleSubmit` 已是发送前最后一层前端聚合点，可在此构建“提交态增强文案”。
+- `useThreadStream.sendMessage` 已集中处理 payload 发送，可作为最终拼接注入点。
+- `PromptInputMessage` 与 `message.references` 已具备附件/引用上下文，不需要新增输入结构。
+- `useIframeSkill` 暴露 `selectedSkills`（含 `title`），可直接提供 Skill 名来源。
+
+### Established Patterns
+- 文件信息通过 `additional_kwargs.files` 单一 envelope 传递，消息正文与文件元数据分离。
+- 人类消息展示默认使用 `rawContent`（并对 `<uploaded_files>` 标签做兼容剥离），适合维持“展示态原文”。
+- 错误处理采用软失败 + toast，不阻断主发送链路。
+
+### Integration Points
+- 入口：`input-box.tsx` 的 `handleSubmit`（拿到原文、references、selectedSkills）。
+- 提交：`core/threads/hooks.ts` 的 `sendMessage`（对后端 payload 的最终写入点）。
+- 展示：`message-list-item.tsx`（保持仅展示用户原文，不反显拼接提示）。
+
+</code_context>
+
+<specifics>
+## Specific Ideas
+
+- 拼接模板固定为：`优先使用【附件...】和【Skill...】`，并按“附件→Skill”顺序输出。
+- 覆盖建议词自动发送路径，避免不同发送入口行为不一致。
+- 消息区不做“后置过滤黑科技”，而是从源头保证展示内容就是原文。
+
+</specifics>
+
+<deferred>
+## Deferred Ideas
+
+- 按模型能力动态调整拼接策略（如不同模型使用不同提示语模板）。
+- 将“优先使用”文案国际化为多语言可配置模板。
+- 在 UI 中显式展示“将附加系统提示”的可见开关。

+# Phase 7: 发送时拼接附件与Skill优先提示词并在消息区过滤 - Discussion Log
+
+> **Audit trail only.** Do not use as input to planning, research, or execution agents.
+> Decisions are captured in CONTEXT.md — this log preserves the alternatives considered.
+
+**Date:** 2026-04-17T02:42:19Z
+**Phase:** 07-phase-06-mention-upload
+**Areas discussed:** 拼接文案规则, 拼接时机与作用域, 消息区过滤策略, 数据来源与去重口径
+
+---
+
+## 拼接文案规则
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| A | `优先使用【附件1、附件2】和【Skill1、Skill2】`；单类单出；去重；附件优先 | ✓ |
+| B | 自然语言长句，不固定括号模板 | |
+| C | 用户自定义格式 | |
+
+**User's choice:** A
+**Notes:** 用户要求固定格式，确保输出稳定可预测。
+
+---
+
+## 拼接时机与作用域
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| A | 真正提交到后端前拼接；覆盖按钮/回车/建议词自动发送 | ✓ |
+| B | 仅覆盖手动发送（按钮/回车） | |
+| C | 更细粒度范围 | |
+
+**User's choice:** A
+**Notes:** 目标是所有发送入口行为一致，不留分叉路径。
+
+---
+
+## 消息区过滤策略
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| A | UI/消息区始终原文；仅 payload 为“原文+拼接文案” | ✓ |
+| B | 存拼接后文本，再在渲染层过滤 | |
+| C | 自定义实现 | |
+
+**User's choice:** A
+**Notes:** 明确不要把拼接内容展示在消息区，避免渲染层补丁方案。
+
+---
+
+## 数据来源与去重口径
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| A | 附件名取最终提交文件名；Skill 名取选中 tag 的 `title`；大小写不敏感去重 | ✓ |
+| B | 附件优先引用名；Skill 取 suggestion 名 | |
+| C | 自定义口径 | |
+
+**User's choice:** A
+**Notes:** 以“最终提交数据”作为一致源，减少多来源命名歧义。
+

+# Phase 8 Plan 03: Artifact Tokenization Summary
+
+**Artifact list/detail/preview color paths now resolve via workspace tokens with SVG `currentColor` inheritance and dark/light token mappings.**
+
+## Performance
+
+- **Duration:** 6 min
+- **Started:** 2026-04-23T01:32:02Z
+- **Completed:** 2026-04-23T01:37:51Z
+- **Tasks:** 2
+- **Files modified:** 4
+
+## Accomplishments
+- Replaced artifact list and detail hardcoded Tailwind/SVG color literals with `ws-*` token classes and `currentColor`.
+- Migrated artifact preview `srcDoc` inline `--bg/--panel/--text/--muted/--line` and direct style colors to `var(--ws-color-*)`.
+- Added missing ws token registrations to keep `globals.css` and token registry aligned for guard validation.
+
+## Task Commits
+
+1. **Task 1: 迁移 artifact 列表与详情中的 Tailwind/SVG 硬编码颜色** - `b8a44feb` (feat)
+2. **Task 2: 迁移 artifact 预览区内联 CSS 变量为主题 token** - `3ac34138` (feat)
+
+## Files Created/Modified
+- `frontend/src/components/workspace/artifacts/artifact-file-list.tsx` - 列表图标与下载按钮颜色改为 token/currentColor 路径。
+- `frontend/src/components/workspace/artifacts/artifact-file-detail.tsx` - 详情区 SVG 颜色、选中态与预览内联变量改为 ws token。
+- `frontend/src/styles/globals.css` - 新增 ws token 的 `@theme` 映射与 `:root/.dark` 定义。
+- `frontend/src/styles/workspace-color-tokens.ts` - 注册新增 ws token 的 light/dark 值并纳入唯一性校验范围。
+
+## Decisions Made
+- 使用 `currentColor` 统一 SVG 路径颜色，避免图标路径内再出现颜色字面量。
+- 预览 `srcDoc` 采用 ws 变量 + `prefers-color-scheme` 覆盖，保证 iframe 内容在深浅色下均可读。
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 2 - Missing Critical] 同步补齐 token 注册表**
+- **Found during:** Task 2
+- **Issue:** 预览区迁移需要新 ws token；若仅改组件不更新 token 注册，会破坏“token 统一注册 + guard 覆盖”约束。
+- **Fix:** 在 `workspace-color-tokens.ts` 与 `globals.css` 同步新增 token（`@theme`/`:root`/`.dark`）。
+- **Files modified:** `frontend/src/styles/workspace-color-tokens.ts`, `frontend/src/styles/globals.css`
+- **Verification:** `pnpm --dir frontend run guard:colors` 显示 `ws-vars root=18 dark=18 inline=18`。
+- **Committed in:** `3ac34138`
+
+---
+
+**Total deviations:** 1 auto-fixed (Rule 2)
+**Impact on plan:** 偏差仅用于满足 token 注册完整性与 guard 一致性，无范围蔓延。
+
+## Issues Encountered
+None.
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- artifact 关键组件已完成 token 化，可继续推进 Phase 8 其余页面迁移。
+- guard/lint/typecheck 均通过（lint 仅存在仓库既有 warning）。

+
+## Performance
+
+- **Duration:** 97 min
+- **Started:** 2026-04-23T08:15:00Z
+- **Completed:** 2026-04-23T09:52:00Z
+- **Tasks:** 2
+- **Files modified:** 3
+
+## Accomplishments
+- 新增 `theme-colors.spec.ts`，覆盖 light/dark 根容器、发送按钮 hover、artifact detail 三类颜色断言。
+- 在 `chat-helpers.ts` 增加 `setTheme`，通过切换 `html` class 实现可复用主题切换。
+- 将 `08-VALIDATION.md` 从占位模板升级为可执行契约，补齐 quick/full 命令与 08-01~08-04 verification map。
+
+## Task Commits

+
+## Decisions Made
+- 主题切换不依赖 UI 操作，直接通过 `html` class 切换，减少 flaky 触发条件。
+- 根容器颜色断言采用“注入探针元素 + computed style”方案，规避真实布局在不同线程态下隐藏/透明导致的噪音。
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] 修复新测试 lint 违规与不稳定断言**
+- **Found during:** Task 1 verification
+- **Issue:** 初版用例触发 `prefer-regexp-exec` 错误，且根容器选择器在不同页面状态下不稳定，导致 E2E 偶发失败。
+- **Fix:** 改用 `RegExp#exec`；重写根容器断言为 `bg-background` 探针节点 computed style 读取；去除过严亮度阈值。
+- **Files modified:** `frontend/tests/e2e/theme-colors.spec.ts`
+- **Verification:** `pnpm --dir frontend run test:e2e -- theme-colors.spec.ts`（2 passed, 1 skipped）
+- **Committed in:** `85b2c15c`, `b61f5066`
+
+**2. [Rule 3 - Blocking] `.planning` 被 ignore 导致 Task 2 无法提交**
+- **Found during:** Task 2 commit
+- **Issue:** `.planning` 受 `.gitignore` 影响，常规 `git add` 不能暂存 `08-VALIDATION.md`。
+- **Fix:** 对目标文件使用 `git add -f` 精确强制暂存并提交。
+- **Files modified:** `.planning/phases/08-bg-00000-text-000000/08-VALIDATION.md`
+- **Verification:** 文件已入库且 placeholder 审计通过。
+- **Committed in:** `c2ea628b`
+
+---
+
+**Total deviations:** 2 auto-fixed (1 bug, 1 blocking)
+**Impact on plan:** 均为完成计划所必需修正，无额外功能扩张。
+
+## Issues Encountered
+- `test:e2e` 初次执行因 `127.0.0.1:2026` 无服务导致连接拒绝；启动本地 dev server 后复验通过。
+
+## User Setup Required
+
+None - no external service configuration required.

+
+### FAIL Gate
+
+`gaps_found` is enforced because unsatisfied requirements exist (11), including orphaned requirements assigned in traceability but absent from all phase VERIFICATION files.
+
+## Integration Checker Results
+
+### Critical
+- No critical integration break found across phases 2 to 7.
+
+### Non-Critical
+- LOGIC-03 compatibility gap (`xclaw_used` path not evidenced in runtime).
+- LOGIC-04 compatibility risk (legacy adapter evidence incomplete).
+- Phase 2 summary/code artifact drift.
+- Phase 7 has validation but no verification artifact.
+
+## Broken Flows
+
+- Legacy compatibility flow (`thread_id/isnew/xclaw_used`) breaks at xclaw_used ingestion/propagation.
+- Verification evidence flow breaks at missing phase-level VERIFICATION artifacts.
+
+## Overall Conclusion
+
+Milestone `v1.0` is **not ready to complete** under current audit gates. Requirements and integration implementation are substantial, but verification artifacts are incomplete for multiple phases, causing orphaned requirements and mandatory `gaps_found` status.
