 - [2026-06-22] @backend — **✅ T6.2+T6.3 创作工具箱通用端点稳定**（通用生成器框架后端落地，分支 `feat/t6-creation-toolbox`）。新 `ww_skills.TOOLBOX`(11 条：legacy 3 + 新 8) + `get_tool`（`toolbox_registry.py`，descriptor 在代码无迁移）。3 新端点（`routers/toolbox.py`，已注册）：`GET /skills/toolbox`（描述符列表，legacy 携 `legacy_route`：`codex?gen=world|character` / `/outline`）、`POST .../skills/{tool_key}/generate`（按 `spec.tier` 经新注入缝 `get_tier_gateway_builder` 建网关 → `run_generator` 结构化预览，**不写库**仅落 ledger；未知/legacy→404、项目不存在→404、无凭据→503）、`POST .../skills/{tool_key}/ingest`（仅 `ingest!=None` 工具；world_entities 走 **continuity 预检 409 gate**(`acknowledge_conflicts` 放行) + `partition_writes` 白名单 + schema→JSONB 写库，outline 细纲按 idx 拼 beats upsert；不可入库→422）。PURE context 派发 `services/toolbox_context.build_toolbox_context`（4 策略，缺章/大纲→空节拍不报错）。response/request schema `schemas/toolbox.py`（concrete 子模型，非裸 dict）。守不变量 #2/#3/#9。TDD：注册表 7 + context 8 + 端点 11 = **+26 测**。**全仓门禁绿**：ruff/format 干净、mypy **183 Success**（隔离 cache）、alembic **无漂移**（无新迁移）、pytest **578 passed**。OpenAPI 新增 3 端点 → **@frontend 须 `cd apps/web && pnpm gen:api`**（T6 前端前置）。记 contracts C3 扩（T6.2/T6.3）。
 - [2026-06-20] @frontend — **Tier4 完成**（T4-a 全局 AI 工具条 + T4-b 本章指令直通生成，分支 `feat/ux-tier4-ai-toolbar`，未并 develop）。T4-a：新 `lib/nav/ai-tools.ts`(aiToolItems) + `components/AiToolbar.tsx` 服务端组件，AppShell 顶栏下仅项目页渲染（写本章/审稿/大纲/设定库/工具箱常驻一排，写本章=朱砂主动作），用 `--chrome` CSS 变量统一 chrome 高度（项目页 7rem=header4+toolbar3，余 4rem），6 个固定高度页改用 `calc(100vh-var(--chrome,4rem))` 适配。T4-b（全链）：后端 `assemble/_build_volatile` 加 `directive` 形参（「本章指令」段领衔 volatile，**绝不入 stable_core**，守缓存前缀不变量 #9），`stream_draft` 加可选 body `DraftStreamRequest{directive}` 透传、`directive_len` 入 log 不记原文、不持久化无迁移，重生成 TS 客户端；前端新 `lib/workbench/directive.ts`(STYLE_PRESETS + composeDirective 纯函数)、`useDraftStream.start(p,no,directive?)` 非空时发 JSON body、Workbench 加可折叠「本章指令」textarea + 风格预设 chips。TDD：ai-tools 4 测 + directive 4 测 + assemble directive 测 + draft 端点 directive/向后兼容 2 测。门禁全绿：后端 ruff/format/mypy(163 文件)/**pytest 479 passed**；前端 lint/tsc/**vitest 213**/build。契约记 contracts C3 扩（T4-b）。

+- [2026-06-29] @frontend/@qa — **UI review follow-up 修复完成**：补 `lib/review/chapterNav.ts` 使新增章导航测试可运行；`ReviewSectionPanel` 改为本地 open 状态，避免用户折叠后重渲染强制弹开；`ReviewReport.hasReport` 纳入 clean review；新增 `tests/test_project_metadata_e2e.py` 用真实 DB 覆盖项目最近编辑/待审稿统计口径。验证：前端 lint/typecheck/vitest **490 passed**/build；后端 ruff/format/mypy、pytest **763 passed**；浏览器抽样 review/settings 无 console error/横向溢出。
