fix(cli): always use localhost for auth callback in browser login

When the app URL pointed to a remote private IP (e.g. 192.168.11.200),
the CLI incorrectly used that IP as the callback host. The callback
HTTP server runs on the CLI's local machine, but the browser redirect
would target the remote server's IP on a random port that isn't open
there — breaking the entire auth flow for remote self-hosted setups.

Since openBrowser() always opens the browser on the same machine as the
CLI, the callback must always target localhost.

Closes #1056

-## Desktop-specific Rules
-
-These rules apply to `apps/desktop/` only. Web has different constraints (URL bar, SSR, no tabs) and doesn't share these concerns. Every rule in this section was added after a concrete bug — treat them as enforced, not suggestions.
-
-### Route categories
-
-Every path in the desktop app falls into exactly one category. Choosing the wrong one reproduces bugs we've already fixed.
-
-- **Session routes** — workspace-scoped pages (`/:slug/issues`, `/:slug/settings`). Rendered by the per-tab memory router under `WorkspaceRouteLayout`. These are legitimate tab destinations.
-- **Transition flows** — pre-workspace / one-shot actions (create workspace, accept invite). **NOT routes.** They live as `WindowOverlay` state, dispatched when the navigation adapter sees `push('/workspaces/new')` or `push('/invite/<id>')`. The shared view (`NewWorkspacePage`, `InvitePage`) is the content; the overlay wrapper supplies platform chrome.
-- **Error / stale states** — "workspace not available", tabs pointing at a revoked workspace. **NOT pages.** `WorkspaceRouteLayout` auto-heals by dropping the stale tab group from the store; the user never lands on an explicit error screen. Web keeps `NoAccessPage` (shareable URL makes the error state meaningful); desktop has no URL bar so stale = heal silently.
-
-**Adding a new pre-workspace flow on desktop**: register a new `WindowOverlay` type in `stores/window-overlay-store.ts`. Do NOT add it to `routes.tsx`. If a shared view needs the flow on both platforms, add the route on web (`apps/web/app/(auth)/...`) AND the overlay type on desktop — the shared view component is identical.
-
-### Workspace identity singleton
-
-`setCurrentWorkspace(slug, uuid)` in `@multica/core/platform` is the single source of truth for "which workspace is active right now". Three consumers depend on it:
-
-1. API client's `X-Workspace-Slug` header.
-2. Zustand per-workspace storage namespace.
-3. Chrome gating (`{slug && <AppSidebar />}` on desktop, similar on web).
-
-Normally set by `WorkspaceRouteLayout` when its route mounts. Critically: **unmount does NOT clear it.** Any code that leaves workspace context (leave workspace, delete workspace, force navigation to overlay) must call `setCurrentWorkspace(null, null)` explicitly — otherwise the realtime `workspace:deleted` handler races the mutation, chrome gating stays truthy while the workspace is gone from cache, and `useWorkspaceId` throws.
-
-### Workspace destructive operations
-
-Leave / Delete workspace flows must follow this order:
-
-1. Read destination from cached workspace list (no extra fetch).
-2. `setCurrentWorkspace(null, null)`.
-3. `navigation.push(destination)` — switch to next workspace or open new-workspace overlay.
-4. THEN `await mutation.mutateAsync(workspaceId)`.
-
-Reversing step 4 with steps 1–3 (mutate first, navigate after) causes a three-way race between the mutation's `onSettled` invalidate, the explicit `navigateAway`, and the realtime handler's `relocateAfterWorkspaceLoss` — all refetching the same `workspaces` query concurrently. One gets cancelled, bubbles as `CancelledError`, and triggers `window.location.assign` → full renderer reload / white screen.
-
-### Tab isolation
-
-Tabs are grouped per workspace in `stores/tab-store.ts`. The TabBar shows only the active workspace's tabs; cross-workspace tab leakage is impossible by construction (no flat global tabs array).
-
-Cross-workspace `push(path)` is detected by the navigation adapter (`platform/navigation.tsx`) and translated into `switchWorkspace(slug, targetPath)` — NOT a navigation within the current tab's router. Don't bypass the adapter; always go through `useNavigation()` from shared code.
-
-### Drag region (macOS window-move)
-
-Every full-window desktop view (login, overlay, any page that covers the native title bar) needs a top drag strip so users can move the window. On macOS the traffic lights are hidden via `useImmersiveMode` in overlay-style contexts, so the drag strip also gives back that corner for pointer-drag.
-
-**Pattern**: flex child at top, not absolute overlay.
-
-```tsx
-<div className="fixed inset-0 z-50 flex flex-col bg-background">
-  <div className="h-12 shrink-0" style={{ WebkitAppRegion: "drag" }} />
-  <div className="flex-1 overflow-auto" style={{ WebkitAppRegion: "no-drag" }}>
-    {/* page content — interactive elements need their own "no-drag" */}
-  </div>
-</div>
-```
-
-Why flex, not absolute: the absolute-strip + `z-index` approach relies on stacking-context hit-testing, which isn't reliable for `-webkit-app-region`. A real flex row with no siblings at that pixel is unambiguous. Height matches `MainTopBar` (48px / `h-12`) for consistency.
-
-Canonical examples: `components/window-overlay.tsx`, `pages/login.tsx`.
-
-### UX vs platform chrome
-
-UX affordances (Back button, Log out button, welcome copy, invite card) belong in `packages/views/` so web and desktop render identical content. Platform chrome (drag strip, `useImmersiveMode`, tab system interaction, traffic-light accommodation) lives in desktop-only code. Violating this split always produces platform divergence — if a button exists on desktop but not on web for the same flow, it's a signal the UX escaped into platform code.
-
 ## UI/UX Rules
 
 - Prefer shadcn components over custom implementations. Install via `pnpm ui:add <component>` from project root — adds to `packages/ui/components/ui/`. All components use Base UI primitives (`@base-ui/react`), not Radix.

-## Full-Stack Isolated Testing
-
-This section covers running the complete stack (backend, frontend, daemon) from
-source in a fully isolated environment. Useful for testing end-to-end changes
-that span multiple components, or for automated CI/AI workflows that need zero
-human intervention.
-
-### Why Not Just `make daemon`?
-
-`make daemon` uses the system-installed CLI's stored token and connects to
-whatever server is configured in `~/.multica/config.json`. That's fine for
-day-to-day development against a shared server, but for fully isolated testing
-you need:
-
-- a local backend and frontend (from source)
-- a local daemon (from source) with its own profile
-- automated authentication (no browser login)
-- no interference with your production CLI config
-
-### Dynamic Profile Naming
-
-Each worktree must use a unique daemon profile to avoid collisions when
-multiple features run in parallel.
-
-The profile name is derived from the worktree directory using the same
-slug + hash pattern as `scripts/init-worktree-env.sh`:
-
-```bash
-WORKTREE_DIR="$(basename "$PWD")"
-SLUG="$(printf '%s' "$WORKTREE_DIR" | tr '[:upper:]' '[:lower:]' | sed 's/[^a-z0-9]/_/g; s/__*/_/g; s/^_//; s/_$//')"
-HASH="$(printf '%s' "$PWD" | cksum | awk '{print $1}')"
-OFFSET=$((HASH % 1000))
-PROFILE="dev-${SLUG}-${OFFSET}"
-```
-
-Example: worktree at `../multica-feat-auth` produces profile
-`dev-multica_feat_auth-347`, matching that worktree's port and database
-allocation.
-
-### Start the Isolated Environment
-
-Run all steps from the worktree root (where the Makefile is).
-
-#### 1. Start backend, frontend, and database
-
-```bash
-make dev
-```
-
-Wait for the backend to be healthy:
-
-```bash
-PORT=$(grep '^PORT=' .env.worktree 2>/dev/null || grep '^PORT=' .env | head -1 | cut -d= -f2)
-PORT=${PORT:-8080}
-SERVER="http://localhost:${PORT}"
-
-for i in $(seq 1 30); do
-  curl -sf "$SERVER/health" > /dev/null 2>&1 && break
-  sleep 2
-done
-```
-
-#### 2. Create a test user and token (automated auth)
-
-In non-production environments the verification code is fixed at `888888`:
-
-```bash
-curl -s -X POST "$SERVER/auth/send-code" \
-  -H "Content-Type: application/json" \
-  -d '{"email": "dev@localhost"}'
-
-JWT=$(curl -s -X POST "$SERVER/auth/verify-code" \
-  -H "Content-Type: application/json" \
-  -d '{"email": "dev@localhost", "code": "888888"}' | jq -r '.token')
-
-PAT=$(curl -s -X POST "$SERVER/api/tokens" \
-  -H "Authorization: Bearer $JWT" \
-  -H "Content-Type: application/json" \
-  -d '{"name": "auto-dev", "expires_in_days": 365}' | jq -r '.token')
-```
-
-#### 3. Create a workspace
-
-```bash
-WS=$(curl -s -X POST "$SERVER/api/workspaces" \
-  -H "Authorization: Bearer $PAT" \
-  -H "Content-Type: application/json" \
-  -d '{"name": "Dev", "slug": "dev"}' | jq -r '.id')
-```
-
-#### 4. Compute profile name and write CLI config
-
-```bash
-# Compute profile (see Dynamic Profile Naming above)
-WORKTREE_DIR="$(basename "$PWD")"
-SLUG="$(printf '%s' "$WORKTREE_DIR" | tr '[:upper:]' '[:lower:]' | sed 's/[^a-z0-9]/_/g; s/__*/_/g; s/^_//; s/_$//')"

-
-```bash
-make cli ARGS="daemon start --profile $PROFILE"
-```
-
-The daemon runs from the current worktree's Go source, connecting to the
-local backend. Agent-executed `multica` commands automatically use the same
-binary (the daemon prepends its own directory to `PATH`).
-
-### Stop the Isolated Environment

-
-# 1. Stop daemon
-make cli ARGS="daemon stop --profile $PROFILE"
-
-# 2. Stop backend + frontend
-make stop            # main checkout
-make stop-worktree   # worktree checkout

-# 3. (Optional) Stop shared PostgreSQL
-make db-down
-
-# 4. (Optional) Clean build artifacts
-make clean

-
-### Desktop App Local Testing
-
-To test the Electron desktop app against a local backend:
-
-```bash
-# After backend is running (make dev)
-pnpm dev:desktop
-```
-
-This automatically:
-
-1. Compiles the `multica` CLI from `server/cmd/multica` into
-   `apps/desktop/resources/bin/multica`
-2. Creates an isolated profile named `desktop-localhost-<PORT>`
-3. Starts and manages its own daemon instance
-4. Connects to the local backend
-
-Login in the Desktop UI with `dev@localhost` and code `888888`.
-
-If the backend runs on a non-default port (worktree), create
-`apps/desktop/.env.development.local`:
-
-```bash
-VITE_API_URL=http://localhost:<backend-port>
-VITE_WS_URL=ws://localhost:<backend-port>/ws
-```
-
-### Isolation Guarantee
-
-Nothing in this flow touches the system-installed `multica` or the default
-`~/.multica/config.json`:
-
-| Resource | System / Production | Local Dev (per-worktree) |
-|---|---|---|
-| Config | `~/.multica/config.json` | `~/.multica/profiles/dev-<slug>-<hash>/config.json` |
-| Daemon PID | `~/.multica/daemon.pid` | `~/.multica/profiles/dev-<slug>-<hash>/daemon.pid` |
-| Health port | `19514` | `19514 + 1 + (name_hash % 1000)` |
-| Workspaces dir | `~/multica_workspaces/` | `~/multica_workspaces_dev-<slug>-<hash>/` |
-| Database | remote / production | local Docker: `multica_<slug>_<hash>` |
-| Desktop profile | `desktop-api.multica.ai` | `desktop-localhost-<port>` |
-
-Multiple worktrees can run simultaneously without conflict.

-# Architecture Audit — Workspace & Realtime Cache
-
-> 基于代码审计整理的 4 个任务。优先级：P0 一个、P1 一个、P2 两个。每个任务都包含问题、根因、受影响的 issue、复现步骤、修复方案、改动范围。
-
----
-
-## 任务 1 — [P0] 空闲后列表数据陈旧
-
-**关联 issue**：[#951](https://github.com/multica-ai/multica/issues/951)
-
-### 问题
-
-用户登录后静置一段时间，Issue 列表里缺失一部分数据（其他成员期间新建/变更的 issue 不出现）。登出再登入可以恢复。`ec5af33b` 声称 "Closes #951"，但 issue 仍为 OPEN 状态 —— 因为它只修了 401 一种场景，没修 WS 半开这一种。
-
-### 根因
-
-系统把 cache 新鲜度的全部责任压给了 WebSocket 推送：
-
-- `packages/core/query-client.ts:7` — `staleTime: Infinity`，cache 永不主动过期
-- `packages/core/query-client.ts:9` — `refetchOnWindowFocus: false`，tab 重新获得焦点也不 refetch
-- 依赖 WS 推送 `issue:created` / `issue:updated` 事件 invalidate cache
-
-但 WS 层存在一个**不对称**：
-
-- **服务端**：`server/internal/realtime/hub.go:83-96, 420-475` 有 54s ping / 60s pongWait，会清理死连接
-- **客户端**：`packages/core/api/ws-client.ts`（142 行全貌）**完全没有心跳检测**，只靠 `onclose` 事件触发重连
-
-浏览器原生 `WebSocket` API 不把 ping/pong 帧暴露给 JS，所以 JS 层无法主动探测 "半开" 连接。当 NAT / 负载均衡器 / 笔记本睡眠导致 TCP 连接被静默切断时：
-
-1. 浏览器 `readyState` 仍是 `OPEN`
-2. `onclose` 不触发
-3. `ws-client.ts:70-73` 的 3 秒重连逻辑不跑
-4. `packages/core/realtime/use-realtime-sync.ts:462-487` 的 `onReconnect` 全量 invalidate 不跑
-5. 期间的 WS 事件进黑洞
-6. cache 保持旧快照
-
-### 复现
-
-**浏览器 DevTools 里的 "Block request URL" 不行** —— 那会触发 `onclose`，走正常重连 → 不复现。真正的半开需要在网络层静默丢包。
-
-**方法 A（推荐，最接近真实场景）**：macOS 用 pfctl 丢包
-
-```bash
-# 假设后端在 8080
-sudo pfctl -E
-echo "block drop out quick proto tcp to any port 8080" | sudo pfctl -f -
-
-# 观察:
-# - Console 里没有 "disconnected, reconnecting in 3s" 日志
-# - Network 里 WS 连接仍显示 Pending / 101
-# 用另一个账号/CLI 创建一个 issue
-# 回到原客户端: 列表不更新
-# 登出再登入: 列表恢复完整
-
-sudo pfctl -d  # 解除
-```
-
-**方法 B（不动网络）**：临时修改代码，在 `packages/core/api/ws-client.ts:52` 的 `onmessage` 处理器里加一行 `return;` 在前面，吞掉所有入站消息。效果等价于半开。
-
-### 修复方案（三个选项，推荐 C）
-
-#### 选项 A — 浏览器端心跳探活（治本，改动大）
-
-在 `ws-client.ts` 加客户端侧的心跳检测：记录 `lastMessageTime`，定时器检查若超过 N 秒没收到任何消息就主动 `ws.close()`，触发现有重连逻辑。
-
-- 优点：从根本上解决半开问题
-- 缺点：浏览器原生 API 没有 ping 能力，需要服务端配合发"应用层 heartbeat"消息供客户端更新 `lastMessageTime`；服务端改 + 客户端改
-
-#### 选项 B — Page Visibility API 触发 invalidate（治标，改动小）
-
-在 `packages/core/platform/core-provider.tsx` 加 `visibilitychange` 监听，tab 重新可见时强制 `queryClient.invalidateQueries({ queryKey: issueKeys.all(wsId) })`（及其他关键 key）。
-
-- 优点：~10 行代码，能兜住 80% 场景（睡眠、切后台 tab）
-- 缺点：treats symptom, 不是真正的半开检测；对"一直保持 tab 可见但网络层断了"的场景无效
-
-#### 选项 C — **A + B 组合**（推荐）
-
-- 短期上 B，立刻止血
-- 中期上 A，把 cache 新鲜度从"只信 WS"改成"WS 是优化，Visibility 是兜底"
-- 可选加 `refetchOnWindowFocus: true` 或把 `staleTime` 改成一个有限值（比如 5 min），作为第三层保险
-
-### 改动范围
-
-| 方案 | 文件 | 改动规模 |
-|---|---|---|
-| B | `packages/core/platform/core-provider.tsx` | ~10 行 |
-| A 客户端 | `packages/core/api/ws-client.ts` | ~30 行 |
-| A 服务端 | `server/internal/realtime/hub.go` | 加 app-level heartbeat message |
-
-### 验证
-
-修完之后：
-
-1. 跑方法 A 复现流程，确认数据不再丢失
-2. 加 e2e 测试：模拟 `document.dispatchEvent(new Event('visibilitychange'))` + 验证 issue list 被 refetch

-## 任务 2 — [P1] Workspace 不在 URL 路径中
-
-**关联 issue**：MUL-723（slug 不在 URL）、MUL-43（切换 workspace 报错）、MUL-509（手机端无法切换）
-
-> **注意**：审计中提到的 MUL-43 / MUL-476 issue 编号需要当面核对一次 —— agent 查询 GitHub 后返回的标题对不上（看起来是别的 PR）。交接时请让执行人以具体症状为准。
-
-### 问题
-
-当前 workspace 身份完全靠 `X-Workspace-ID` HTTP header + Zustand store + localStorage 承载，URL 里没有 workspace 信息。所有路径都是 `/issues`、`/issues/:id` 这种 workspace-agnostic 的。
-
-### 根因
-
-**数据库和 API 已经支持 slug**：
-
-- `server/migrations/001_init.up.sql:15-23` — workspace 表有 `slug TEXT UNIQUE NOT NULL`
-- `server/pkg/db/queries/workspace.sql:11-13` — 有 `GetWorkspaceBySlug` 查询
-- `packages/core/types/workspace.ts:8-19` — Workspace 类型里有 slug 字段
-
-**但前端路由和导航层没用它**：
-
-- Web 路由：`apps/web/app/(dashboard)/` 下 25 个 route file 都是 workspace-implicit
-- Desktop 路由：`apps/desktop/src/renderer/src/routes.tsx:71-143` 同样
-- Navigation 适配器 `apps/web/platform/navigation.tsx` 直接透传 `router.push`，没有任何 workspace 前缀逻辑
-
-**workspace 切换只靠 sidebar UI**（`packages/views/layout/app-sidebar.tsx:284-286`）：
-
-```tsx
-if (ws.id !== workspace?.id) {
-  push("/issues");              // 硬跳 /issues（workspace-implicit！）
-  switchWorkspace(ws);           // 然后改 store
-}
-```
-
-这种设计使得：
-
-- 手机端因为没 sidebar UI，也没 URL 层切换入口，**完全切不了 workspace**（MUL-509）
-- 把 `/issues/xxx` 链接发给处于不同 workspace 的同事，会打开错误 workspace 下的 issue，或找不到报错（MUL-43 系列）
-- 分享链接没有 workspace 上下文，接收方必须先手动切对 workspace
-
-### 复现
-
-1. **MUL-723**：登录 → 观察地址栏，没有任何 workspace 标识
-2. **MUL-43**：
-   - 加入两个 workspace A 和 B
-   - 在 A 中打开某个 issue `/issues/abc123`
-   - 切到 B，URL 不变 → 访问失败 / 显示错数据
-3. **MUL-509**：手机浏览器打开，尝试切 workspace → 无法切换（UI 不显示 sidebar 触发器或触发器无法切）
-
-### 修复方案（三个选项，推荐 A）
-
-#### 选项 A — `/ws/:slug/...` URL 前缀（根本方案，推荐）
-
-所有路径加上 workspace slug 前缀。例如 `/issues/abc123` → `/ws/my-team/issues/abc123`。
-
-**要改的地方**：
-
-1. **Web 路由目录结构**：`apps/web/app/(dashboard)/` 下全部搬到 `apps/web/app/(dashboard)/ws/[slug]/...`（~25 个文件）
-2. **Desktop 路由**：`apps/desktop/src/renderer/src/routes.tsx:71-143` 给所有路径加 `/ws/:slug` 前缀
-3. **Navigation 适配器**：
-   - `apps/web/platform/navigation.tsx` — `push(path)` 内部前置 `/ws/${workspace.slug}`，`pathname` 读取时去掉前缀
-   - `apps/desktop/src/renderer/src/platform/navigation.tsx` — 同上
-4. **Sidebar 切换逻辑**：`packages/views/layout/app-sidebar.tsx:284-286` 改成 `push('/ws/${ws.slug}/issues')`（或依赖适配器自动加前缀就不用改）
-5. **服务端中间件**：`server/internal/middleware/workspace.go:41-46` 增加 "从 URL path 解析 slug → 查 ID → 校验 membership" 的逻辑，header 继续作为 fallback（迁移期兼容）
-
-**预计改动**：~50-100 个文件（大部分是 route 搬迁，不是逻辑改动）、~5-7 人天
-
-**不改也能工作的部分**：
-- `packages/core/api/client.ts` — 仍旧走 header，不用改
-- 所有 `packages/views/` 下的组件 —— 它们用 `useNavigation().push()` 抽象，适配器层处理前缀就行
-
-**风险**：
-- 旧的 bookmark URL 失效（如果产品还没正式 ship，问题不大）
-- E2E 测试需要更新所有 URL 断言
-
-#### 选项 B — `?ws=slug` query param（折中）
-
-URL 形如 `/issues?ws=my-team`。改动更小（~30 个文件），URL 丑但向后兼容。推荐度低于 A。
-
-#### 选项 C — 只修症状不动架构
-
-在 `switchWorkspace` 和各个 query 之间加 debounce、error boundary 等 workaround。不解决根因，技术债越攒越多。**不推荐**。
-
-### 改动范围（选项 A）
-
-| 模块 | 文件数 | 备注 |
-|---|---|---|
-| Web routes | ~25 | 目录搬迁 |
-| Desktop routes | 1 | 路径前缀 |
-| Navigation adapters | 2 | 前缀逻辑 |
-| Server middleware | 1-2 | slug → ID 解析 |
-| 组件（不用改） | 30-40 | 用 `useNavigation` 的不受影响 |
-| E2E tests | 20-30 | URL 断言更新 |
-
----
-
-## 任务 3 — [P1] Workspace 切换时 navigation 状态未隔离
-
-**关联 issue**：MUL-43（切换报错）、MUL-476（本地缓存未按 workspace 隔离）
-
-> 同上，这两个编号建议交接时核对症状。
-
-### 问题
-
-绝大多数 workspace-scoped 的 Zustand store 都正确使用了 `createWorkspaceAwareStorage`（key 后缀加 wsId 自动隔离），但 **`useNavigationStore` 是个例外**：它持久化了 `lastPath`，但用的是 global storage，切换 workspace 后里面仍是上个 workspace 的路径。
-
-### 根因
-
-**`packages/core/navigation/store.ts:15-31`**：
-
-```typescript
-export const useNavigationStore = create<NavigationState>()(
-  persist(
-    (set) => ({
-      lastPath: "/issues",
-      onPathChange: (path) => { /* ... */ set({ lastPath: path }); },
-    }),
-    {
-      name: "multica_navigation",
-      storage: createJSONStorage(() => createPersistStorage(defaultStorage)), // ← 这里用的是 global，不是 workspace-aware
-      partialize: (state) => ({ lastPath: state.lastPath }),
-    }
-  )
-);
-// ← 没有调 registerForWorkspaceRehydration
-```
-
-**对比：其他 store 都是正确的**：
-
-| Store | 是否 workspace-aware | 是否注册 rehydration |
-|---|---|---|
-| useNavigationStore | ❌ | ❌ |
-| useIssuesScopeStore | ✅ | ✅ |
-| useIssueDraftStore | ✅ | ✅ |
-| useRecentIssuesStore | ✅ | ✅ |
-| useIssueViewStore | ✅ | ✅ |
-| myIssuesViewStore | ✅ | ✅ |
-| useChatStore | ✅（手动用 wsKey）| ✅ |
-
-另外 `packages/core/platform/storage-cleanup.ts:10-19` 的 `WORKSPACE_SCOPED_KEYS` 列表里也漏了 `multica_navigation`。
-
-**现有的 workaround**：`packages/views/layout/app-sidebar.tsx:285` 切 workspace 时硬跳到 `/issues`，正是为了绕开这个 bug。修好 navigation store 之后这行 hack 可以删掉。
-
-### 复现
-
-1. 在 workspace A 中打开一个具体 issue `/issues/abc123`
-2. 切到 workspace B
-3. 观察：如果没有 sidebar 的硬跳 workaround，会尝试恢复到 `/issues/abc123`，但那个 issue 不属于 B，导致 404 或错误
-
-目前因为有硬跳 workaround，症状表现为"切 workspace 后总是回到 issue 首页"—— 这本身也是 bug（用户期望记住上次位置）。
-
-### 修复方案（推荐 Option C：组合）
-
-**三处改动**：
-
-1. `packages/core/navigation/store.ts:28` —— 把 `createPersistStorage(defaultStorage)` 改成 `createWorkspaceAwareStorage(defaultStorage)`
-2. 同文件在末尾加：`registerForWorkspaceRehydration(() => useNavigationStore.persist.rehydrate());`
-3. `packages/core/platform/storage-cleanup.ts:10-19` 的 `WORKSPACE_SCOPED_KEYS` 数组里加 `"multica_navigation"`
-
-**可选**：清理 `packages/views/layout/app-sidebar.tsx:285` 的 `push("/issues")` workaround（改完之后不再需要）。
-
-### 改动范围
-
-| 文件 | 改动 |
-|---|---|
-| `packages/core/navigation/store.ts` | 改 storage 类型、加 rehydration 注册（~3 行） |
-| `packages/core/platform/storage-cleanup.ts` | 数组加一行 |
-| `packages/core/platform/workspace-storage.test.ts` | 加 rehydration 的单测 |
-| `packages/views/layout/app-sidebar.tsx`（可选） | 移除硬跳 workaround |
-
-**风险**：极低。只是把 navigation store 对齐到其他 store 已经在用的模式。

-## 任务 4 — [P2] Workspace 生命周期副作用散落
-
-**关联 issue**：MUL-727（创建后闪页）、MUL-728（删除确认）、MUL-820（接受邀请不自动切）
-
-### 问题
-
-创建 / 删除 / 切换 / 加入 workspace 的副作用分散在 mutation 的 `onSuccess` 和各处 UI 回调里，没有统一抽象。几个具体 bug：
-
-### 4.1 MUL-727 — 创建 workspace 后闪一下 `/issues` 再跳 `/onboarding`
-
-**根因**：两个 `onSuccess` 回调同时跑，顺序不确定。
-
-- `packages/core/workspace/mutations.ts:7-21` 的 `useCreateWorkspace.onSuccess` 里调了 `switchWorkspace(newWs)` —— 同步改 Zustand，`/issues` 路由开始用新 workspace 渲染
-- `packages/views/modals/create-workspace.tsx:68-70` 的 UI `onSuccess` 里调了 `router.push("/onboarding")` —— 异步 schedule 导航
-
-于是：`/issues` 先渲染（闪一下）→ 导航到 `/onboarding`。
-
-**修复**：把 `switchWorkspace` 从 mutation 里拿出来，让 UI 层主导。在 `create-workspace.tsx` 的 `onSuccess` 里先 `switchWorkspace` 再 `push`，保证同一个微任务里完成。
-
-**文件**：`packages/core/workspace/mutations.ts`、`packages/views/modals/create-workspace.tsx`、可能 `packages/views/onboarding/step-workspace.tsx`
-
-### 4.2 MUL-728 — 删除 workspace 的"缺少确认"
-
-**核查结果**：`packages/views/settings/components/workspace-tab.tsx:102-119, 236-255` **已经有 AlertDialog 确认**了。
-
-**真实问题**：删除成功后**没有导航**，用户停在 `/settings`，而当前 workspace 已经是删除后系统挑的另一个。
-
-**修复**：在 `handleDeleteWorkspace` 的 `onConfirm` 成功分支里加 `push("/issues")`。
-
-**文件**：`packages/views/settings/components/workspace-tab.tsx`（加一行）
-
-### 4.3 MUL-820 — 接受邀请不自动切换 workspace
-
-**核查结果**：有两条路径：
-
-- ✅ `/invite/:id` 独立页（`packages/views/invite/invite-page.tsx:32-52`）是**正确的**：accept → switchWorkspace → push("/issues")
-- ❌ **Sidebar 下拉里的 "Join" 按钮**（`packages/views/layout/app-sidebar.tsx:203-209, 321-324`）**是错的**：只 invalidate cache，不切也不跳
-
-**修复（推荐 Option 2）**：Sidebar 的 "Join" 改成跳转到 `/invite/:id` 页面，不再就地接受。单一入口、单一行为。
-
-```tsx
-<DropdownMenuItem onClick={() => push(`/invite/${inv.id}`)}>
-  {inv.workspace_name}
-</DropdownMenuItem>
-```
-
-**文件**：`packages/views/layout/app-sidebar.tsx`（~10 行）
-
-### 复现
-
-| Issue | 步骤 |
-|---|---|
-| MUL-727 | 创建新 workspace → 仔细看是否闪了一下 `/issues` 再跳 `/onboarding` |
-| MUL-728 | 删除当前 workspace → 观察删完后是否留在 `/settings` 页面（BUG: 没有自动跳走） |
-| MUL-820 | 被邀请用户登录 → sidebar 下拉 → 点 "Join" → 观察当前 workspace 是否切过去（BUG: 不切）|
-
-### 长期架构建议（可选）
-
-抽一个 `useWorkspaceLifecycle` hook 统一管这些副作用。Agent 报告里有完整设计，文件：`packages/core/workspace/hooks.ts`（新建）。但建议先修 MUL-727/728/820 三个具体 bug，hook 抽象作为后续迭代。
-
-### 改动范围
-
-| Issue | 文件 | 改动规模 |
-|---|---|---|
-| MUL-727 | mutations.ts + create-workspace.tsx | ~10 行 |
-| MUL-728 | workspace-tab.tsx | ~1 行 |
-| MUL-820 | app-sidebar.tsx | ~10 行 |
-
----
-
-## 总览
-
-| 任务 | Issue | 优先级 | 预估规模 | 风险 |
-|---|---|---|---|---|
-| 1. WS 半开 + 陈旧 cache | #951 | **P0** | Option B ~10 行；Option C ~1-2 天 | 低 |
-| 2. Workspace URL 化 | MUL-723/43/509 | P1 | 5-7 人天（大部分是搬迁）| 中（影响面大、e2e 要改）|
-| 3. Navigation store 隔离 | MUL-43/476 | P1 | ~0.5 天 | 低 |
-| 4. Workspace 生命周期 bug | MUL-727/728/820 | P2 | ~1 天 | 低 |
-
-### 建议推进顺序
-
-1. **立刻做**：任务 1 的 Option B（visibilitychange 触发 invalidate）—— 代码最少、收益最明显，能当天止血
-2. **同步开始**：任务 3（navigation store 隔离）—— 影响小、风险低、顺便清掉一个 workaround
-3. **规划立项**：任务 2（URL 化）—— 大改造，需要单独开一个 iteration
-4. **次要修补**：任务 4 的三个小 bug —— 可以拆成独立 PR，各自 review
-
-### 重要澄清
-
-- **Issue 编号核对**：MUL-43 / MUL-476 的编号需要核对一次，agent 查询 GitHub 返回的标题看起来对不上（可能是内部 issue tracker 编号 vs GitHub 编号混用）。以症状为准。
-- **MUL-728 实际状态**：确认对话框已经存在，真实缺的是"删除后跳走"。
-- **MUL-820 实际状态**：`/invite/:id` 页面路径工作正常，只是 sidebar 下拉按钮坏了。

-
-If you see `no such host` *inside a Codex session on macOS* but `curl https://multica-api.copilothub.ai` from a plain shell on the same machine works, you are hitting the Seatbelt bug below.
-
-## Root cause
-
-Upstream issue: [openai/codex#10390][codex-10390]. On macOS, Codex's Seatbelt
-profile for `sandbox_mode = "workspace-write"` silently ignores the
-`[sandbox_workspace_write] network_access = true` setting. The seatbelt
-policy hard-codes `CODEX_SANDBOX_NETWORK_DISABLED=1`, which blocks DNS/UDP
-syscalls. Go's `net.LookupHost` surfaces that as `no such host`.
-
-Linux (Landlock) is **not** affected — only macOS Seatbelt.
-
-[codex-10390]: https://github.com/openai/codex/issues/10390
-
-## What the daemon does now
-
-The daemon writes a *multica-managed* block into each task's
-`$CODEX_HOME/config.toml`, delimited by `# BEGIN multica-managed` /
-`# END multica-managed` markers. Anything outside the markers is left
-untouched so users can still tune Codex behavior.
-
-Decision matrix (see [`server/internal/daemon/execenv/codex_sandbox.go`](../server/internal/daemon/execenv/codex_sandbox.go)):
-
-| Host OS   | Codex version                                    | Managed block emits                                                       |
-| --------- | ------------------------------------------------ | ------------------------------------------------------------------------- |
-| non-darwin | any                                              | `sandbox_mode = "workspace-write"` + `sandbox_workspace_write.network_access = true` (dotted-key form) |
-| darwin    | ≥ `CodexDarwinNetworkAccessFixedVersion`         | same as above (upstream fix in effect)                                    |
-| darwin    | older / unknown (current default)                | `sandbox_mode = "danger-full-access"` + warn-level log                     |
-
-The managed block is always hoisted to the top of `config.toml` and uses
-TOML dotted-key syntax rather than a `[sandbox_workspace_write]` section
-header. Both are load-bearing: if the block sat after a user table like
-`[permissions.multica]`, a bare `sandbox_mode = "..."` line would be parsed
-as `permissions.multica.sandbox_mode` and Codex would silently ignore it.
-
-`CodexDarwinNetworkAccessFixedVersion` is an empty string today, meaning *no
-known fixed release yet*. Bump it once a tagged Codex release includes the
-upstream fix.
-
-When the daemon falls back to `danger-full-access`, it logs at `WARN`:
-
-```
-codex sandbox: falling back to danger-full-access on macOS
-  reason=codex on macOS: seatbelt ignores sandbox_workspace_write.network_access (openai/codex#10390) ...
-  codex_version=0.121.0
-  hint=upgrade Codex CLI (e.g. `brew upgrade codex` or `npm i -g @openai/codex`) ...
-  config_path=/.../codex-home/config.toml
-```
-
-## Quick self-check commands
-
-From the host shell (outside the sandbox):
-
-```bash
-# Is the Multica API reachable at all?
-curl -sSf https://multica-api.copilothub.ai/healthz
-```
-
-From inside a Codex session (after the daemon writes its config):
-
-```bash
-multica issue list --limit 1 --output json >/dev/null && echo OK
-```
-
-If the host curl works but the Codex-session call fails with `no such host`,
-the sandbox is the culprit; confirm the daemon picked the right policy by
-looking at the managed block in `$CODEX_HOME/config.toml`.
-
-## Options and trade-offs
-
-- **A. Domain-scoped `permissions` profile** (tight): when the upstream
-  `network_access` fix is available, prefer writing a `permissions.multica`
-  profile that allows only `multica-api.copilothub.ai` and
-  `multica-static.copilothub.ai`. Keeps filesystem sandbox intact.
-- **B. `danger-full-access`** (current macOS fallback): drops the whole
-  Seatbelt profile. Simplest reliable workaround until the upstream fix is
-  released.
-- **C. Upgrade Codex CLI**: `brew upgrade codex` or `npm i -g @openai/codex`.
-  Once a release containing [openai/codex#10390][codex-10390] is installed,
-  bump `CodexDarwinNetworkAccessFixedVersion` in `codex_sandbox.go` and
-  option A/the workspace-write path takes over automatically.
-
-## If you need to hand-verify
-
-```bash
-# Inspect the managed block the daemon wrote for a given task.
-sed -n '/# BEGIN multica-managed/,/# END multica-managed/p' \
-  ~/multica_workspaces/$WORKSPACE_ID/$TASK_SHORT/codex-home/config.toml
-```
-
-The block is idempotent — re-running a task rewrites it in place.

-# Unify Workspace Identity Resolver Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Fix broken file uploads caused by the workspace slug refactor (v2, PR #1138/#1141), and eliminate the structural bug source that allowed it. File uploads from within a workspace on the desktop and web apps currently land in S3 without a corresponding DB attachment record — the file is orphaned and the UI never sees it.
-
-**Architecture:** The server currently has **two independent implementations** of the same logic — extract the workspace UUID from an HTTP request. One lives in the workspace middleware (post-v2, accepts slug header → DB lookup → UUID). The other lives inside the handler package (pre-v2, only accepts UUID header/query). The v2 refactor updated the middleware one and forgot the handler one; routes that sit *outside* the workspace middleware group (notably `/api/upload-file`) still run through the stale resolver and can't translate the frontend's new `X-Workspace-Slug` header.
-
-The root cause is duplication. The fix is to collapse both resolvers into a single shared function that middleware and handlers both delegate to, so any future change to "how do we read workspace identity" is impossible to forget. The existing middleware's resolver already has the full logic; we extract it into a package-level function and have the handler helper call it.
-
-**Tech Stack:** Go (Chi router, sqlc, pgx).
-
-**Non-goals:**
-- No frontend changes. The frontend has been sending `X-Workspace-Slug` since v2; this plan makes the server finish accepting it everywhere.
-- No route reshuffling. `/api/upload-file` stays outside `RequireWorkspaceMember` because it serves two distinct use cases (avatar upload + workspace attachment); the avatar path needs to work without a workspace context.
-- No change to CLI / daemon clients. They still send `X-Workspace-ID` (UUID); the resolver keeps UUID as a fallback.

----
-
-## Background: what's broken and why
-
-**Frontend (current, post-v2):** `ApiClient.authHeaders()` in `packages/core/api/client.ts:121` sends:
-```
-X-Workspace-Slug: <slug>
-```
-
-**Server middleware resolver** (`server/internal/middleware/workspace.go:53-86`, `resolveWorkspaceUUID`): accepts the slug header, looks up the slug via `queries.GetWorkspaceBySlug`, and writes the resolved UUID into the request context. Every handler behind `RequireWorkspaceMember` / `RequireWorkspaceRole` / `RequireWorkspaceMemberFromURL` sees the UUID in context and works correctly.
-
-**Handler resolver** (`server/internal/handler/handler.go:155-165`, `resolveWorkspaceID`): a parallel implementation used by handlers that are NOT behind the workspace middleware. It only checks:
-1. `middleware.WorkspaceIDFromContext(r.Context())`
-2. `?workspace_id` query param
-3. `X-Workspace-ID` header
-
-Never touches slug, because it has no `*db.Queries` access (it's a package-level function, not a method).
-
-**Impact:** `/api/upload-file` (registered at `server/cmd/server/router.go:166`, in the user-scoped group, outside workspace middleware) calls `resolveWorkspaceID(r)`, gets `""` because the frontend only sends slug, thinks "no workspace context", and silently skips the DB attachment record creation (`server/internal/handler/file.go:235-245`). The file reaches S3; the UI never sees it.
-
-**Why `/api/upload-file` is outside workspace middleware:** it serves both "avatar upload (no workspace)" and "attachment upload (with workspace)", branching on the resolved workspace ID inside the handler. Moving it under `RequireWorkspaceMember` would break avatar uploads.
-
-**Structural root cause:** two resolvers, same job, divergent capabilities. The duplication is what let v2 ship "mostly working" — most handlers live behind middleware, so the broken handler resolver had a low blast radius that wasn't caught in review.
-
----
-
-### Task 1: Extract shared resolver into middleware package
-
-**Problem:** The middleware's `resolveWorkspaceUUID` closure captures `*db.Queries` and can look up slugs. The handler's `resolveWorkspaceID` is a bare package-level function without queries access. We need a single implementation both sides can reuse. Putting it in the `middleware` package is fine — the `handler` package already imports `middleware`.
-
-**Files:**
-- Modify: `server/internal/middleware/workspace.go`
-
-**Step 1: Add `ResolveWorkspaceIDFromRequest` export**
-
-After `errWorkspaceNotFound` (around line 45), add a package-level exported function that takes `(r *http.Request, queries *db.Queries)` and returns the workspace UUID as a string (empty if none found or slug doesn't resolve).
-
-Priority order (mirrors `resolveWorkspaceUUID`, plus a context lookup first so handlers behind middleware still get the fast path):
-
-```go
-// ResolveWorkspaceIDFromRequest returns the workspace UUID for an HTTP
-// request, using the same priority order as the workspace middleware.
-// Handlers behind workspace middleware get it from context (cheap); handlers
-// outside middleware (e.g. /api/upload-file) still resolve slug → UUID via
-// a DB lookup instead of silently falling through to "no workspace".
-//
-// Priority:
-//  1. middleware-injected context (if the route is behind workspace middleware)
-//  2. X-Workspace-Slug header → GetWorkspaceBySlug → UUID (post-refactor frontend)
-//  3. ?workspace_slug query → GetWorkspaceBySlug → UUID
-//  4. X-Workspace-ID header (CLI/daemon compat)
-//  5. ?workspace_id query (CLI/daemon compat)
-//
-// Returns "" when no identifier was provided OR a slug was provided but doesn't
-// resolve to any workspace. Callers that need the "slug provided but invalid"
-// distinction should use the resolver inside the middleware directly.
-func ResolveWorkspaceIDFromRequest(r *http.Request, queries *db.Queries) string {
-    if id := WorkspaceIDFromContext(r.Context()); id != "" {
-        return id
-    }
-    if slug := r.Header.Get("X-Workspace-Slug"); slug != "" {
-        if ws, err := queries.GetWorkspaceBySlug(r.Context(), slug); err == nil {
-            return util.UUIDToString(ws.ID)
-        }
-    }
-    if slug := r.URL.Query().Get("workspace_slug"); slug != "" {
-        if ws, err := queries.GetWorkspaceBySlug(r.Context(), slug); err == nil {
-            return util.UUIDToString(ws.ID)
-        }
-    }
-    if id := r.Header.Get("X-Workspace-ID"); id != "" {
-        return id
-    }
-    return r.URL.Query().Get("workspace_id")
-}
-```
-
-**Step 2: Refactor `resolveWorkspaceUUID` to delegate**
-
-The existing middleware closure has slightly different semantics (returns `errWorkspaceNotFound` when a slug was provided but doesn't resolve, so middleware can 404 instead of 400). Keep that, but share the resolution logic:
-
-Leave `resolveWorkspaceUUID` as-is for now — it distinguishes "no identifier" (400) from "invalid slug" (404). `ResolveWorkspaceIDFromRequest` returns "" in both cases because handler-level callers don't need that distinction (they just check for empty).
-
-Document in a comment near `resolveWorkspaceUUID` that it's an internal variant that preserves the error distinction for middleware gating, and point to `ResolveWorkspaceIDFromRequest` as the handler-facing API.
-
-**Step 3: Build and verify**
-
-```bash
-cd server && go build ./...
-```
-Expected: clean build.
-
-**Step 4: Commit**
-
-```
-refactor(server): extract ResolveWorkspaceIDFromRequest from middleware
-
-Introduces a shared helper that consolidates the workspace-identity
-resolution logic used by both the workspace middleware and the handler
-package. No behavior change yet — callers still use the old functions.
-Sets up the next commit to fix the /api/upload-file slug bug by routing
-the handler-side resolver through this shared function.
-```
-
----
-
-### Task 2: Promote handler resolver to a method + delegate
-
-**Problem:** The package-level `resolveWorkspaceID(r *http.Request)` in `handler.go` can't call `GetWorkspaceBySlug` because it has no queries access. Promoting it to a method on `*Handler` gives it access to `h.Queries` at no syntactic cost elsewhere.
-
-**Files:**
-- Modify: `server/internal/handler/handler.go:155-165`
-
-**Step 1: Replace `resolveWorkspaceID` with a Handler method**
-
-```go
-// resolveWorkspaceID resolves the workspace UUID for this request.
-// Delegates to middleware.ResolveWorkspaceIDFromRequest so routes inside
-// and outside workspace middleware see identical resolution behavior.
-//
-// Returns "" when no workspace identifier was provided or a slug was
-// provided but doesn't match any workspace.
-func (h *Handler) resolveWorkspaceID(r *http.Request) string {
-    return middleware.ResolveWorkspaceIDFromRequest(r, h.Queries)
-}
-```
-
-Delete the old package-level `resolveWorkspaceID` function.
-
-**Step 2: Build — expect errors at 47 call sites**
-
-```bash
-cd server && go build ./... 2>&1 | head -60
-```
-
-Expected: `resolveWorkspaceID is not a value` or `undefined: resolveWorkspaceID` errors at each existing call site. That's the signal to run Task 3.
-
-**Do not commit yet.** Task 2 and 3 are a single logical change; they commit together after Task 3 fixes the compile.
-
----
-
-### Task 3: Rename 47 call sites to `h.resolveWorkspaceID(r)`
-
-**Problem:** Every `resolveWorkspaceID(r)` call in the handler package now fails to compile because the function became a method. All 47 call sites are inside methods on `*Handler` (or similar receiver types that have access to `h`), so the rename is mechanical.
-
-**Files affected** (verified via `grep -rn "resolveWorkspaceID" server/internal/handler/`):
-
-- `server/internal/handler/handler.go:275, 365, 388` (3 sites)
-- `server/internal/handler/issue.go:447, 559, 731, 783, 1294, 1476` (6 sites)
-- `server/internal/handler/activity.go:133` (1 site)
-- `server/internal/handler/autopilot.go:178, 203, 255, 306, 386, 414, 490, 578, 615, 662` (10 sites)
-- `server/internal/handler/project.go:80, 127, 150, 192, 273, 430` (6 sites)
-- `server/internal/handler/comment.go:443, 510` (2 sites)
-- `server/internal/handler/runtime.go:207, 247, 296` (3 sites)
-- `server/internal/handler/pin.go:59, 105, 175, 202` (4 sites)
-- `server/internal/handler/reaction.go:43, 110` (2 sites)
-- `server/internal/handler/skill.go:126, 146, 187, 384, 815` (5 sites)
-- `server/internal/handler/agent.go:158, 254` (2 sites)
-- `server/internal/handler/file.go:83, 115, 282, 306` (4 sites)
-
-Total: 48 (the resolver declaration itself + 47 callers).
-
-**Step 1: Mechanical rename**
-
-For each file above, change every `resolveWorkspaceID(r)` to `h.resolveWorkspaceID(r)`. In the one case in `file.go:83` inside `groupAttachments`, the receiver is already `*Handler`, so the method is accessible.
-
-**Semantic check:** all 47 call sites are on methods with an `h *Handler` receiver (verifiable by scrolling up a few lines from each grep match). If any call site is inside a non-method function, that site needs to either take `*Handler` as a parameter or be skipped from this rename. Spot-check three sites before doing the rename.
-
-**Step 2: Build**
-
-```bash
-cd server && go build ./...
-```
-Expected: clean build.
-
-**Step 3: Run Go tests**
-
-```bash
-cd server && go test ./...
-```
-Expected: all pass. The 46 call sites behind workspace middleware hit the context branch (identical behavior to before). Only `UploadFile` gains new capability (slug resolution); it wasn't tested before, will be covered in Task 4.
-
-**Step 4: Commit**
-
-```
-fix(server): resolve X-Workspace-Slug in /api/upload-file and other middleware-less handlers
-
-The v2 workspace URL refactor updated the workspace middleware to accept
-X-Workspace-Slug but left the handler-package resolveWorkspaceID helper
-(used by handlers outside the middleware group) stuck on X-Workspace-ID.
-The frontend switched to the slug header, so /api/upload-file was
-receiving a slug it couldn't translate to a UUID, silently falling
-through to the avatar-upload branch and skipping DB attachment record
-creation — files were landing in S3 with no database reference.
-
-Promote resolveWorkspaceID to a Handler method and delegate to the new
-middleware.ResolveWorkspaceIDFromRequest so middleware-behind and
-middleware-outside handlers share the same resolution logic. The 46
-call sites that live inside the workspace middleware group are
-unaffected (context lookup still wins). /api/upload-file now correctly
-recognizes slug requests and creates the attachment record.
-
-Fixes: missing DB attachment rows for files uploaded since v2 (#1141)
-```
-
----
-
-### Task 4: Add handler test for upload-file with slug header
-
-**Problem:** The bug manifested exactly because there was no test covering the "upload-file with only a slug header" code path. Prevent regression.
-
-**Files:**
-- Modify: `server/internal/handler/file_test.go` (or create if absent)
-
-**Step 1: Locate existing upload-file test infrastructure**
-
-```bash
-grep -rn "UploadFile\|upload-file" server/internal/handler/*_test.go
-```
-
-If there's an existing upload-file test, add a new test case alongside it. If not, scaffold one using the same `handler_test.go` fixture pattern (`testWorkspaceID`, `testUserID`, seeded workspace).
-
-**Step 2: Write the test**
-
-Test name: `TestUploadFile_ResolvesWorkspaceViaSlugHeader`.
-
-Flow:
-1. Seed a workspace with a known slug and the default test user as a member.
-2. POST a multipart form to `/api/upload-file` with an `issue_id` field referencing a seeded issue, with only `X-Workspace-Slug: <slug>` in headers (no `X-Workspace-ID`).
-3. Assert response is 200.
-4. Assert a DB row exists in `attachments` with the expected `workspace_id`, `uploader_id`, `issue_id`, and `filename`.
-
-Anti-regression: also add `TestUploadFile_ResolvesWorkspaceViaIDHeaderStill` to confirm legacy `X-Workspace-ID` header still works (CLI / daemon compat).
-
-**Step 3: Run the new test**
-
-```bash
-cd server && go test ./internal/handler/ -run UploadFile
-```
-Expected: both pass.
-
-**Step 4: Commit**
-
-```
-test(server): cover upload-file slug and UUID header resolution
-
-Regression test for the v2 refactor bug: uploads from the frontend
-(which sends X-Workspace-Slug) now reach the workspace-aware branch
-and create attachment records.
-```
-
----
-
-### Task 5: Add unit test for the shared resolver
-
-**Problem:** The shared function will be the single point through which all workspace identity resolution flows. It deserves table-driven test coverage for each priority level.
-
-**Files:**
-- Create or modify: `server/internal/middleware/workspace_test.go`
-
-**Step 1: Table test**
-
-Cases to cover:
-- Context UUID present → returns context UUID, ignores headers/query
-- Only `X-Workspace-Slug` → DB lookup succeeds → returns UUID
-- Only `X-Workspace-Slug` → DB lookup fails → returns ""
-- Only `?workspace_slug` → DB lookup succeeds → returns UUID
-- Only `X-Workspace-ID` → returns UUID
-- Only `?workspace_id` → returns UUID
-- Slug header + UUID header both present → slug wins (frontend priority)
-- Nothing → returns ""
-
-**Step 2: Run**
-
-```bash
-cd server && go test ./internal/middleware/ -run ResolveWorkspaceIDFromRequest
-```
-Expected: all cases pass.
-
-**Step 3: Commit**
-
-```
-test(server): table-driven coverage for ResolveWorkspaceIDFromRequest
-
-Pins down the priority order (context > slug header > slug query >
-UUID header > UUID query) so future changes can't silently diverge.
-```
-
----
-
-### Task 6: Full verification
-
-**Step 1: `make check`**
-
-```bash
-make check
-```
-Expected: typecheck, TS tests, Go tests, E2E (if backend+frontend up) all green.
-
-**Step 2: Manual smoke test**
-
-1. Start desktop dev environment.
-2. Open an issue, attach a file via drag-and-drop or the file picker.
-3. Refresh the issue. The attachment should appear in the attachments list.
-
-Before this fix: attachment silently disappears on refresh (file is in S3, DB has no row).
-
-**Step 3: Open PR**
-
-Branch name: `fix/unify-workspace-identity-resolver`.
-
-Title: `fix(server): resolve X-Workspace-Slug in middleware-less handlers`
-
-Body should:
-- Link to the symptom PR (v2 refactor #1141) and reference that it's a latent follow-up.
-- Describe the structural change (two resolvers → one).
-- Note that 46 of 47 call sites see zero behavior change (context branch wins); only `/api/upload-file` gains capability.
-
----
-
-## Risk / blast radius
-
-**Low risk.** The 46 middleware-protected callers hit the context branch in `ResolveWorkspaceIDFromRequest` identically to how they hit `WorkspaceIDFromContext` before — zero semantic change. The only new code path exercised in production is the slug-header branch for `/api/upload-file`, which is already exercised by every other slug-header-carrying request (just via the middleware's version of the same logic). Task 4 and 5 lock the behavior down with tests.
-
-## Rollback plan
-
-If a regression surfaces after deploy, revert the single commit from Task 3. `ResolveWorkspaceIDFromRequest` and the Handler method remain but are unused — harmless dead code until the next attempt.

-# Workspace URL 化重构 — 项目汇报
-
-**日期**：2026-04-15
-**作者**：Naiyuan
-**状态**：调研完成，待评审
-
----
-
-## 一、为什么要做
-
-当前 workspace 上下文完全靠 `X-Workspace-ID` HTTP header + Zustand store + localStorage 承载，URL 里**不含任何 workspace 信息**。所有路径都是 `/issues`、`/issues/:id` 这种 workspace-agnostic 的。
-
-这个设计已经在产品里直接表现为 3 个已知问题：
-
-1. **分享链接不可靠**（MUL-43）：`/issues/abc` 发给另一个成员，会用他自己 localStorage 里的 workspace 去解析，导致 404 或看到错误 workspace 的数据
-2. **手机端无法切 workspace**（MUL-509）：切换只靠 sidebar UI，手机端不展开 sidebar 就没有切换入口
-3. **多 tab 互相覆盖**：`multica_workspace_id` 是全局 localStorage key，两个 tab 打开不同 workspace 会互相污染
-
-除了这 3 个显性 bug，架构上的"多份 workspace 状态拷贝互相同步"也带来一些隐性问题（创建 workspace 闪页、切换 workspace 时 cache 竞态等），积累时间越长后续改动越难。
-
-行业惯例（Linear / Notion / Vercel / GitHub）都是 `/{workspace-slug}/...` 的 URL 形态，把 URL 当作 workspace 的唯一来源。这是我们应该对齐的最佳实践。
-
-## 二、调研结论
-
-### 好消息：基础设施已经就位
-
-- 数据库 `workspace.slug` 字段已经存在（`TEXT UNIQUE NOT NULL`），用户创建时手动指定且不可修改
-- 后端已有 `GetWorkspaceBySlug` 查询
-- 前端 `Workspace` 类型已包含 `slug` 字段
-- Web 端认证已经切换为 HttpOnly cookie 模式，Next.js middleware 可读到登录态
-
-也就是说这次改造**不需要大量后端改动**，主要是前端路由和状态管理的重新组织。
-
-### 坏消息：范围比最初估计大
-
-初看以为只是"URL 前缀加个 slug"，调研后发现必须一起做的事情有：
-
-1. **URL 路由重组**：web 端所有 dashboard 路由迁到 `app/[workspaceSlug]/(dashboard)/*`；desktop 端所有 react-router 路由加 `/:workspaceSlug` 前缀
-2. **状态管理清理**：删除 `useWorkspaceStore.workspace` 作为独立状态，改为从 URL 派生；删除 `hydrateWorkspace` / `switchWorkspace` actions（切 workspace 变成纯导航）；删除 `localStorage["multica_workspace_id"]`
-3. **所有路径引用替换**：`push("/issues")` 改为 path builder（`paths.issues()`），影响 ~25 个组件文件
-4. **Mutation 副作用重构**：`useCreateWorkspace` / `useLeaveWorkspace` / `useDeleteWorkspace` 里的 `switchWorkspace` 调用全部移除（这些调用正是 MUL-727 闪页、MUL-728 删除后不跳转、MUL-820 接受邀请不切 workspace 等一系列 bug 的根因）
-5. **桌面端 tab 系统适配**：tab 路径天然包含 workspace，切 workspace = 开新 tab 或导航，不再有全局切换动作
-6. **Shareable URL 修复**：桌面端 `getShareableUrl` 当前生成 `https://www.multica.ai/issues/abc`（缺 slug），需要更新
-7. **后端保留词校验**：slug 不能和前端顶级路由冲突（`login`、`onboarding`、`invite`、`api`、`settings` 等），后端创建时校验
-8. **内部 markdown 链接兼容**：issue 评论里写的 `[foo](/issues/abc)` 触发的 `multica:navigate` 事件需要自动补当前 workspace slug
-
-### 不需要改的（边界已确认）
-
-- 邮件邀请链接 `/invite/{id}` — 接受邀请是 pre-workspace 流程，不需要 slug
-- `mention://type/id` 协议 — 只存 UUID，workspace-agnostic
-- CLI 登录 URL — `/login` 也是 pre-workspace，不需要 slug
-- 后端 API 路径 — 保持 `/api/workspaces/{id}`，slug 仅用于前端 URL
-- 桌面端 `multica://auth/callback` — 认证回调，不涉及 workspace
-
-## 三、方案要点
-
-**核心原则**：URL 是 workspace 上下文的唯一 source of truth，其他状态都是派生态。
-
-**URL 形状**：`/{workspace-slug}/issues/{id}` （和 Linear / Notion 一致）
-
-**切换 workspace = 导航**：sidebar 下拉改为 `<Link href="/{new-slug}/issues">`，不再有命令式的 `switchWorkspace` 函数。这样一次性消除前面列出的一大批 mutation 副作用 bug。
-
-**预估影响面**：~30-35 个文件，其中约 20 个是机械替换（hardcoded 路径 → path builder），真正需要思考的核心逻辑改动集中在 5-6 个文件。
-
-**一个 PR 合并**：中间状态不可运行（URL 结构是原子变化），不拆 PR。worktree 里充分开发和自测，一次 review 合并。
-
-## 四、执行与测试计划
-
-### 执行阶段
-
-1. **本周内**：完成方案详细实施文档（精确到文件 / 行号 / 代码片段）
-2. **下一步**：在独立 worktree 上开发，AI 辅助写代码，过程中人工 review
-3. **开发完成后**：本地跑全套验证（`make check` — TypeScript + 单测 + Go 测试 + E2E）
-
-### 测试阶段
-
-1. **本地自测**：
-   - 已知功能路径（创建 / 浏览 / 搜索 issue，切换 workspace，接受邀请，分享链接）
-   - 已知 bug 场景（MUL-43 / MUL-509 / MUL-727 / MUL-820）逐一验证已修复
-   - 多 tab 场景（两个 tab 打开不同 workspace 互不影响）
-2. **测试环境部署**：本地通过后发测试环境，全员试用几天，观察：
-   - 是否有回归（特别是导航流、创建/删除 workspace、邀请流程）
-   - URL 使用感受（分享、收藏、刷新）
-3. **灰度 / 生产**：测试环境稳定后推生产
-
-### 风险提示
-
-- **唯一的硬中断点**：现有的 `/issues` 等 URL 在重构后会 404（产品还没正式 ship、用户量可忽略，所以不做兼容性重定向）
-- **E2E 测试断言**：约 20-30 处 URL 断言需要更新
-- **后端保留词清单**：如果现有 workspace 里有名字撞到保留词的（例如正好叫 `settings`），需要提前 migrate（可能性极低，因 slug 限制较严）
-
-## 五、附注
-
-这次重构会**顺带修掉**以下已登记 issue，不需要单独开 PR：
-
-| Issue | 修复方式 |
-|---|---|
-| MUL-43（切换 workspace 报错 / 分享链接失效） | URL 带 slug，根本解决 |
-| MUL-509（手机端无法切 workspace） | 切换变导航，手机能点链接就能切 |
-| MUL-723（workspace 不在 URL） | 核心目标 |
-| MUL-727（创建 workspace 闪 /issues） | 删除 mutation 里的 switchWorkspace 副作用 |
-| MUL-728（删除 workspace 后留在 /settings） | 删除成功后 navigate 到下一个 workspace |
-| MUL-820（sidebar Join 不切 workspace） | Join 改成跳转到 `/invite/{id}` 走统一路径 |
-
-不在本次范围内的：Issue #951（WebSocket 半开导致 cache 陈旧）—— 这是 realtime 层独立问题，单独 PR 处理。
