工单移交（handoff）实施计划

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: 同事在 A 机把工单（worktree + claude/codex 会话）打包挂到 Gitea 工单附件并重新指派，我在 B 机一键接管：重建 worktree、装回会话文件、写本机字段，之后 resume / 合并 / 解冲突照常。

Architecture: 会话包 spx-handoff-issue-<N>.tgz（handoff.json 清单 + claude/ + codex/）作为 Gitea 工单附件传输；共享 state JSON 新增两个字符串字段 handoffAttachmentId / handoffFrom 标记「待接管」；接管方用 git worktree add -B <branch> <path> origin/<branch> 重建 worktree，再把会话文件装到对应 ~/.claude/projects/<encoded cwd>/ 目录（先删本机所有同 sid 副本）。纯 fs / 纯决策逻辑拆成小模块配 vitest；副作用编排放 panel/handlers/handoffFlow.ts。

Tech Stack: TypeScript、VS Code Extension API、Node 22 全局 fetch/FormData/Blob、tar CLI、React 19 + Tailwind 4（webview）、Vitest、Go（spx 的 schema 副本）。

Spec: docs/superpowers/specs/issue-handoff/spec.md

Global Constraints

• 所有命令在 /home/cruldra/Sources/superwork/vscode 下执行（pnpm test / pnpm lint / pnpm typecheck；Go 用 cd cli && make test）。
• 代码文件用 Serena MCP 工具读写（mcp__serena__find_symbol / replace_symbol_body / insert_after_symbol / replace_content）；非代码文件（md / json）才用 Read/Edit。
• 提交信息格式：emoji + type(scope) + 中文描述（参考 git log，例：✨ feat(vscode): …、♻️ refactor(vscode): …、🐛 fix(vscode): …）。提交信息末尾加一行 Claude-Session: https://claude.ai/code/session_011cEyL6k351U2BzX1Qmygph。
• 注释只讲「为什么 / 坑」，不复述代码，不留历史痕迹（不写「原来是…现在改成…」）。
• src/panel/messages.ts 与 webview-ui/src/lib/messages.ts、src/gitea/types.ts 与 webview-ui/src/types.ts 是手工镜像，改一处必改另一处。
• state JSON 清空字段用 '' 墓碑；issue/patch 清空字段用 null（undefined 会被 postMessage 丢掉）。
• 移交只支持 Gitea 工单（issue.source !== 'youtrack'）。
• 仅 POSIX：打包/解包直接 execFile('tar', …)。
• 会话 id 与 ~/.claude/projects 目录编码：encodeCwdForProjectsDir(abs) = abs.replace(/[/.]/g, '-')，projectsDirFor(abs) = ~/.claude/projects/<encoded>（已有，src/cc/sessionWatcher.ts）。

Task 1: state JSON 字段 + Issue 类型 + loader

Files:

• Modify: schemas/state-json.schema.json
• Modify: cli/cmd/spx/main.go:391-411
• Modify: src/gitea/stateJson.ts:22
• Modify: src/youtrack/stateComment.ts:23
• Modify: src/gitea/types.ts:10-99
• Modify: webview-ui/src/types.ts:3+
• Modify: src/gitea/issueLoader.ts:70-203, 293-397
• Modify: src/panel/messages.ts:43,45
• Modify: webview-ui/src/lib/messages.ts（同两行）

Interfaces:

• Produces: Issue.handoffAttachmentId?: string、Issue.handoffFrom?: string、Issue.assignees?: string[]；issues/update 消息多 me?: string；issue/patch 支持 handoffAttachmentId?: string | null、handoffFrom?: string | null、assignees?: string[]、sessionId?: string | null、testSessionId?: string | null。

• Step 1: schema 加字段

在 schemas/state-json.schema.json 的 properties 末尾（autoReview 之后）追加：

    "handoffAttachmentId": {
      "type": "string",
      "description": "移交会话包在 Gitea 的附件 id；存在即「待接管」，接管完成后清空。",
      "minLength": 1
    },
    "handoffFrom": {
      "type": "string",
      "description": "发起移交的 Gitea login。",
      "minLength": 1
    }

• Step 2: Go 侧同步

cli/cmd/spx/main.go 的 knownStateFields 加：

	"handoffAttachmentId":   {},
	"handoffFrom":           {},

运行：cd cli && make sync-schema && make test Expected: ok .../internal/state（schema_test 通过，副本一致）

• Step 3: TS 两处 KNOWN_STATE_FIELDS

src/gitea/stateJson.ts:22 与 src/youtrack/stateComment.ts:23 的数组末尾各加 'handoffAttachmentId', 'handoffFrom'。

• Step 4: Issue 类型（两份镜像）

src/gitea/types.ts 的 Issue 在 autoReview?: boolean 之后加：

  /** Gitea assignee login 列表；接管按钮只对 assignee 含当前登录者的工单显示。 */
  assignees?: string[]
  /** 移交会话包的 Gitea 附件 id（字符串）；存在即「待接管」。 */
  handoffAttachmentId?: string
  /** 发起移交的 Gitea login。 */
  handoffFrom?: string

webview-ui/src/types.ts 的 Issue 加同样三个字段。

• Step 5: issueLoader 解析

src/gitea/issueLoader.ts parseColumnFromComments：

• 返回类型加 handoffAttachmentId?: string、handoffFrom?: string
• obj 断言类型加 handoffAttachmentId?: unknown、handoffFrom?: unknown
• 在 const autoReview = … 后加：

      const handoffAttachmentId = typeof obj.handoffAttachmentId === 'string' && obj.handoffAttachmentId.length > 0
        ? obj.handoffAttachmentId
        : undefined
      const handoffFrom = typeof obj.handoffFrom === 'string' && obj.handoffFrom.length > 0
        ? obj.handoffFrom
        : undefined

• 返回对象加 handoffAttachmentId, handoffFrom。

buildIssue：解构处加 handoffAttachmentId, handoffFrom；返回对象 htmlUrl 之前加：

    ...(handoffAttachmentId ? { handoffAttachmentId } : {}),
    ...(handoffFrom ? { handoffFrom } : {}),
    assignees: (issue.assignees ?? []).map(a => a.login),

• Step 6: 消息类型（两份镜像）

src/panel/messages.ts:43 改为：

    | { type: 'issues/update', issues: Issue[], scope: 'mine' | 'all', globalAutoReview: boolean, youtrackConfigured: boolean, me?: string }

:45 的 issue/patch patch 对象：sessionId?: string → sessionId?: string | null，testSessionId?: string → testSessionId?: string | null，并在末尾追加 , assignees?: string[], handoffAttachmentId?: string | null, handoffFrom?: string | null。

webview-ui/src/lib/messages.ts 同两行做同样修改。

• Step 7: KanbanPanel 发 me

src/panel/KanbanPanel.ts loadAndPush 里 this.postMessage({ type: 'issues/update', … }) 之前加 const me = await loginForToken(host, token)（import loginForToken from '../auth/identity'），消息里加 me。

• Step 8: 校验并提交

Run: pnpm typecheck && pnpm lint && pnpm test Expected: 全部通过。

git add schemas cli src webview-ui
git commit -m "✨ feat(vscode): state JSON 新增 handoffAttachmentId/handoffFrom，Issue 透出 assignees"

Task 2: git/worktreePath.ts（抽出 slug / 模板解析）

Files:

• Create: src/git/worktreePath.ts
• Create: src/git/worktreePath.test.ts
• Modify: src/panel/handlers/sessions.ts:636-680（删除私有 deriveSlug / resolveWorktreeDir，改 import）、:768-770

Interfaces:

• Produces:

  • export const DEFAULT_WORKTREE_TEMPLATE = '~/Sources/worktree/$project_name/$feature_name'
  • export function deriveSlug(planFile: string): string
  • export function slugFromBranch(branch: string): string
  • export function resolveWorktreeDir(template: string, workspaceRoot: string, slug: string): string

• Step 1: 写测试

src/git/worktreePath.test.ts：

import * as os from 'node:os'
import * as path from 'node:path'
import { describe, expect, it } from 'vitest'
import { DEFAULT_WORKTREE_TEMPLATE, deriveSlug, resolveWorktreeDir, slugFromBranch } from './worktreePath'

describe('deriveSlug', () => {
  it('取 plans/ 后一段', () => {
    expect(deriveSlug('docs/superpowers/plans/foo-bar/plan.md')).toBe('foo-bar')
  })
  it('没有 plans/specs 锚点时退回父目录名', () => {
    expect(deriveSlug('docs/x/baz/plan.md')).toBe('baz')
  })
})

describe('slugFromBranch', () => {
  it('去掉 feature/ 前缀', () => {
    expect(slugFromBranch('feature/foo-bar')).toBe('foo-bar')
  })
  it('无前缀原样返回', () => {
    expect(slugFromBranch('hotfix-1')).toBe('hotfix-1')
  })
})

describe('resolveWorktreeDir', () => {
  it('展开三个占位符与 ~', () => {
    const out = resolveWorktreeDir(DEFAULT_WORKTREE_TEMPLATE, '/w/proj', 'slug')
    expect(out).toBe(path.join(os.homedir(), 'Sources', 'worktree', 'proj', 'slug'))
  })
  it('$project_root 展开为工作区绝对路径', () => {
    expect(resolveWorktreeDir('$project_root/.wt/$feature_name', '/w/proj', 's')).toBe('/w/proj/.wt/s')
  })
})

• Step 2: 跑测试确认失败

Run: pnpm test src/git/worktreePath.test.ts Expected: FAIL（模块不存在）

• Step 3: 实现

src/git/worktreePath.ts：

import { createHash } from 'node:crypto'
import * as os from 'node:os'
import * as path from 'node:path'

export const DEFAULT_WORKTREE_TEMPLATE = '~/Sources/worktree/$project_name/$feature_name'

/**
 * spec/plan 以目录形式存放（docs/superpowers/{specs,plans}/<slug>/…），slug 取
 * `plans`/`specs` 后一段。兜底父目录名，再兜底路径 hash，保证目录名不为空。
 */
export function deriveSlug(planFile: string): string {
  const segments = planFile.split('/').filter(Boolean)
  const anchor = segments.findIndex(s => s === 'plans' || s === 'specs')
  if (anchor >= 0 && segments[anchor + 1])
    return segments[anchor + 1]
  const parent = path.basename(path.dirname(planFile))
  if (parent && parent !== '.' && parent !== '/')
    return parent
  return createHash('sha256').update(planFile).digest('hex').slice(0, 8)
}

/** 实施分支固定形如 `feature/<slug>`；接管方只有分支名，从这里反推 worktree 目录名。 */
export function slugFromBranch(branch: string): string {
  return branch.startsWith('feature/') ? branch.slice('feature/'.length) : branch
}

/**
 * 把 worktreeDirectory 模板展开成绝对路径。`~` 在这里展开：git/execFile 不经 shell，
 * 不会自己做 tilde 展开。
 */
export function resolveWorktreeDir(template: string, workspaceRoot: string, slug: string): string {
  let p = template
    .split('$project_name')
    .join(path.basename(workspaceRoot))
    .split('$project_root')
    .join(workspaceRoot)
    .split('$feature_name')
    .join(slug)
  if (p.startsWith('~'))
    p = path.join(os.homedir(), p.slice(1))
  return path.resolve(p)
}

• Step 4: sessions.ts 改用新模块

删除 src/panel/handlers/sessions.ts 中私有的 deriveSlug、resolveWorktreeDir（:636-680），加 import { DEFAULT_WORKTREE_TEMPLATE, deriveSlug, resolveWorktreeDir } from '../../git/worktreePath'；:768-770 的 || '~/Sources/worktree/$project_name/$feature_name' 改为 || DEFAULT_WORKTREE_TEMPLATE。若 createHash/os 在 sessions.ts 里因此无引用，删掉对应 import。

• Step 5: 跑测试 + 提交

Run: pnpm test src/git/worktreePath.test.ts && pnpm typecheck && pnpm lint Expected: PASS

git add src/git/worktreePath.ts src/git/worktreePath.test.ts src/panel/handlers/sessions.ts
git commit -m "♻️ refactor(vscode): 抽出 worktreePath 模块（slug / 目录模板解析）"

Task 3: ensureWorktreeFromRemote

Files:

• Modify: src/git/worktree.ts:37, 97, 110
• Create: test/git/worktreeFromRemote.test.ts

Interfaces:

• Produces:

  • export function runGit(workspaceRoot: string, args: string[], failLabel?: string): Promise<string>（改 export）
  • export async function findLiveWorktreeForBranch(workspaceRoot: string, branch: string): Promise<string | undefined>（改 export）
  • export async function ensureWorktreeFromRemote(opts: WorktreeOpts): Promise<string>

• Step 1: 写集成测试（真 git，仿 test/git/worktreeEnsure.test.ts）

test/git/worktreeFromRemote.test.ts：

import { execFileSync } from 'node:child_process'
import { existsSync, promises as fsp, rmSync, writeFileSync } from 'node:fs'
import * as os from 'node:os'
import * as path from 'node:path'

}

interface Fixture { root: string, origin: string, repo: string, templatePath: string }

/** origin（bare）← 同事的 clone push feature 分支；repo 是接管方的 clone，只有 main。 */

  const origin = path.join(root, 'origin.git')
  git(root, ['init', '--bare', '-b', 'main', origin])
  const peer = path.join(root, 'peer')
  git(root, ['clone', origin, peer])
  writeFileSync(path.join(peer, 'README.md'), 'hello\n')
  git(peer, ['add', 'README.md'])
  git(peer, ['commit', '-m', 'init'])
  git(peer, ['push', '-u', 'origin', 'main'])

  return { root, origin, repo, templatePath }
}

let fx: Fixture | undefined

    const out = await ensureWorktreeFromRemote({ workspaceRoot: fx.repo, worktreePath: fx.templatePath, branch: 'feature/x' })
    expect(out).toBe(fx.templatePath)

    ).rejects.toThrow(/feature\/none/)
  })
})

• Step 2: 跑测试确认失败

Run: pnpm test test/git/worktreeFromRemote.test.ts Expected: FAIL（ensureWorktreeFromRemote 不存在）

• Step 3: 实现

src/git/worktree.ts：把 function runGit 与 async function findLiveWorktreeForBranch 改为 export。在 ensureWorktree 之后新增：

/**
 * 接管方重建 worktree：分支已在 origin 上，本机从远端 checkout。
 * `-B` 让本地同名残留分支直接对齐远端（发送方移交前已校验全部 push）。
 */
export async function ensureWorktreeFromRemote(opts: WorktreeOpts): Promise<string> {
  const { workspaceRoot, branch } = opts
  const worktreePath = path.resolve(opts.worktreePath)

  await runGit(workspaceRoot, ['fetch', 'origin', branch], `拉取远端分支 ${branch}`)

  // ① 已经有 live worktree → 复用，不动模板路径
  const live = await findLiveWorktreeForBranch(workspaceRoot, branch)
  if (live)
    return live

  // ② 模板路径被垃圾目录占着 → kill + 删，否则 add 撞路径
  if (await pathExists(worktreePath)) {
    killProcessesUsingWorktree(worktreePath)
    await removeWorktreeDir(workspaceRoot, worktreePath)
  }

  await fsp.mkdir(path.dirname(worktreePath), { recursive: true })
  await runGit(
    workspaceRoot,
    ['worktree', 'add', '-B', branch, worktreePath, `origin/${branch}`],
    'git worktree add',
  )
  return worktreePath
}

removeWorktreeDir 是 rm -rf + git worktree prune，对非 worktree 的垃圾目录同样适用；它拒绝少于 3 段的浅路径，测试里的模板路径在 /tmp/sw-remote-*/wt/x 下满足要求。

• Step 4: 跑测试 + 提交

Run: pnpm test test/git/worktreeFromRemote.test.ts && pnpm typecheck && pnpm lint Expected: PASS

git add src/git/worktree.ts test/git/worktreeFromRemote.test.ts
git commit -m "✨ feat(vscode): ensureWorktreeFromRemote 从远端分支重建 worktree"

Task 4: cc/sessionBundle.ts（会话文件查找 / 安装 / codex 定位）

Files:

• Create: src/cc/sessionBundle.ts
• Create: src/cc/sessionBundle.test.ts

Interfaces:

• Produces:

  export interface ClaudeSessionFiles { projectsDir: string, jsonl: string, dir?: string }
  export function claudeProjectsRoot(): string                         // ~/.claude/projects
  export async function listClaudeSessionCopies(sid: string, projectsRoot: string): Promise<ClaudeSessionFiles[]>
  export async function findClaudeSessionFiles(sid: string, projectsRoot: string): Promise<ClaudeSessionFiles | undefined>  // 多份取 jsonl mtime 最新
  export async function copyClaudeSessionFiles(files: ClaudeSessionFiles, dstDir: string): Promise<void>
  export async function installClaudeSession(opts: { sid: string, srcDir: string, dstProjectsDir: string, projectsRoot: string }): Promise<void>
  export async function codexRolloutRelPathFor(sid: string, codexRoot: string): Promise<string | undefined>
  export async function installCodexSession(relPath: string, srcFile: string, codexRoot: string): Promise<void>
  

  installClaudeSession 语义：把 srcDir/<sid>.jsonl（+ srcDir/<sid>/）拷到 dstProjectsDir，然后删除 projectsRoot 下所有 projectsDir !== dstProjectsDir 的副本。srcDir 本身在 projectsRoot 下时（完成列搬迁）也成立。

Task 7: Gitea API：assignees 列表 + 附件

Files:

• Modify: src/gitea/api.ts（末尾追加）

Interfaces:

• Produces:

  export interface GiteaAttachment { id: number, name: string, size: number, uuid: string, browser_download_url: string, created_at: string }
  export async function listRepoAssignees(opts: { host, token, owner, repo }): Promise<GiteaUser[]>
  export async function listIssueAttachments(opts: { host, token, owner, repo, index: number }): Promise<GiteaAttachment[]>
  export async function uploadIssueAttachment(opts: { host, token, owner, repo, index: number, name: string, data: Buffer }): Promise<GiteaAttachment>
  export async function getIssueAttachment(opts: { host, token, owner, repo, index: number, attachmentId: number }): Promise<GiteaAttachment>
  export async function downloadAttachment(opts: { token: string, url: string }): Promise<Buffer>
  export async function deleteIssueAttachment(opts: { host, token, owner, repo, index: number, attachmentId: number }): Promise<void>
  

• Step 1: 实现

在 src/gitea/api.ts 末尾追加（Buffer 从 'node:buffer' import；FormData/Blob 用 Node 22 全局）：

export interface GiteaAttachment {
  id: number
  name: string
  size: number
  uuid: string
  browser_download_url: string
  created_at: string
}

/** 可被指派的用户（仓库协作者 + owner），移交选人用。 */
export async function listRepoAssignees(opts: {
  host: string
  token: string
  owner: string
  repo: string
}): Promise<GiteaUser[]> {
  const res = await fetch(
    `${baseUrl(opts.host)}/repos/${opts.owner}/${opts.repo}/assignees`,
    { headers: authHeaders(opts.token) },
  )
  await ensureOk(res)
  return (await res.json()) as GiteaUser[]
}

export async function listIssueAttachments(opts: {
  host: string
  token: string
  owner: string
  repo: string
  index: number
}): Promise<GiteaAttachment[]> {
  const res = await fetch(
    `${baseUrl(opts.host)}/repos/${opts.owner}/${opts.repo}/issues/${opts.index}/assets`,
    { headers: authHeaders(opts.token) },
  )
  await ensureOk(res)
  return (await res.json()) as GiteaAttachment[]
}

export async function uploadIssueAttachment(opts: {
  host: string
  token: string
  owner: string
  repo: string
  index: number
  name: string
  data: Buffer
}): Promise<GiteaAttachment> {
  const url = new URL(`${baseUrl(opts.host)}/repos/${opts.owner}/${opts.repo}/issues/${opts.index}/assets`)
  url.searchParams.set('name', opts.name)
  const form = new FormData()
  form.append('attachment', new Blob([opts.data], { type: 'application/gzip' }), opts.name)
  // 不能带 Content-Type：multipart boundary 由 fetch 按 FormData 自动生成。
  const res = await fetch(url.toString(), {
    method: 'POST',
    headers: { Authorization: `token ${opts.token}`, Accept: 'application/json' },
    body: form,
  })
  await ensureOk(res)
  return (await res.json()) as GiteaAttachment
}

export async function getIssueAttachment(opts: {
  host: string
  token: string
  owner: string
  repo: string
  index: number
  attachmentId: number
}): Promise<GiteaAttachment> {
  const res = await fetch(
    `${baseUrl(opts.host)}/repos/${opts.owner}/${opts.repo}/issues/${opts.index}/assets/${opts.attachmentId}`,
    { headers: authHeaders(opts.token) },
  )
  await ensureOk(res)
  return (await res.json()) as GiteaAttachment
}

/**
 * `browser_download_url` 走的是 web 路由（/attachments/<uuid>），Gitea 的 web
 * 鉴权组同样接受 `Authorization: token`。未登录时它会 302 到登录页返回 HTML，
 * 所以除 ok 外还要拒掉 HTML 响应，别把登录页当 tgz 存下来。
 */
export async function downloadAttachment(opts: { token: string, url: string }): Promise<Buffer> {
  const res = await fetch(opts.url, { headers: { Authorization: `token ${opts.token}` }, redirect: 'follow' })
  await ensureOk(res)
  const contentType = res.headers.get('content-type') ?? ''
  if (contentType.includes('text/html'))
    throw new GiteaApiError(res.status, `附件下载被重定向到页面（鉴权失败？）：${opts.url}`)
  return Buffer.from(await res.arrayBuffer())
}

export async function deleteIssueAttachment(opts: {
  host: string
  token: string
  owner: string
  repo: string
  index: number
  attachmentId: number
}): Promise<void> {
  const res = await fetch(
    `${baseUrl(opts.host)}/repos/${opts.owner}/${opts.repo}/issues/${opts.index}/assets/${opts.attachmentId}`,
    { method: 'DELETE', headers: authHeaders(opts.token) },
  )
  await ensureOk(res)
}

• Step 2: 用真实 Gitea 验证下载鉴权（一次性脚本，放 scratchpad，不入库）

在本仓库自己的 Gitea（gitea.ailoveworld.cn，git remote -v 取 owner/repo）上挑一个已关闭的测试工单 N，token 从 ~/.config/tea/config.yml 读（若 token 走 keyring，取 GITEA_TOKEN 环境变量）：

T=<token>; O=<owner>; R=<repo>; N=<issue>
echo hi > /tmp/claude-1000/-home-cruldra-Sources-superwork/62cd8318-2051-42ed-9511-9c135e5f9c93/scratchpad/t.txt
curl -s -H "Authorization: token $T" -F "attachment=@/tmp/claude-1000/-home-cruldra-Sources-superwork/62cd8318-2051-42ed-9511-9c135e5f9c93/scratchpad/t.txt" \
  "https://gitea.ailoveworld.cn/api/v1/repos/$O/$R/issues/$N/assets?name=t.txt" | tee /dev/stderr | python3 -c "import json,sys; d=json.load(sys.stdin); print(d['id'], d['browser_download_url'])"
# 用输出的 URL：
curl -sL -o /dev/null -w '%{http_code} %{content_type}\n' -H "Authorization: token $T" <browser_download_url>
# 期望 200 且 content_type 不是 text/html；然后删掉测试附件：
curl -s -X DELETE -H "Authorization: token $T" "https://gitea.ailoveworld.cn/api/v1/repos/$O/$R/issues/$N/assets/<id>"

Expected: 200 text/plain…。若返回 HTML / 302 登录页，改 downloadAttachment 为请求 https://<host>/attachments/<uuid> 并加 ?token= 方案前先把结果报告给用户再定。

• Step 3: typecheck + 提交

Task 9: 消息类型 + handoffFlow.ts + KanbanPanel 分发

Files:

• Modify: src/panel/messages.ts、webview-ui/src/lib/messages.ts
• Create: src/panel/handlers/handoffFlow.ts
• Modify: src/panel/KanbanPanel.ts:335+

Interfaces:

• Produces:

  • 消息：WebviewToExtension 加 { type: 'handoff/users', issueNumber: number }、{ type: 'handoff/start', issueNumber: number, to: string }、{ type: 'handoff/accept', issueNumber: number }；ExtensionToWebview 加 { type: 'handoff/users-result', issueNumber: number, users: string[] }、{ type: 'handoff/done', issueNumber: number }。
  • export async function handleHandoffUsers(panel, issueNumber): Promise<void>
  • export async function handleHandoffStart(panel, issueNumber, to): Promise<void>
  • export async function handleHandoffAccept(panel, issueNumber): Promise<void>

• Step 1: 消息类型（两份镜像）

src/panel/messages.ts ExtensionToWebview 在 issue/pr-diff-summary-done 之后加：

    | { type: 'handoff/users-result', issueNumber: number, users: string[] }
    | { type: 'handoff/done', issueNumber: number }

WebviewToExtension 在 column/change 之后加：

    | { type: 'handoff/users', issueNumber: number }

• Step 3: KanbanPanel 分发

src/panel/KanbanPanel.ts handleMessage 里 column/change 分支之后加：

      void handoffFlow.handleHandoffUsers(this, msg.issueNumber)
      return
    }
    if (msg.type === 'handoff/start') {
      void handoffFlow.handleHandoffStart(this, msg.issueNumber, msg.to)
      return
    }
    if (msg.type === 'handoff/accept') {
      void handoffFlow.handleHandoffAccept(this, msg.issueNumber)
      return
    }

顶部 import * as handoffFlow from './handlers/handoffFlow'。

• Step 4: typecheck + lint + 提交

Run: pnpm typecheck && pnpm lint && pnpm test Expected: PASS

git add src/panel/messages.ts webview-ui/src/lib/messages.ts src/panel/handlers/handoffFlow.ts src/panel/KanbanPanel.ts

Task 10: 完成列会话归档改为整包搬迁

Files:

• Modify: src/panel/handlers/issues.ts:383-433（// Before removing the worktree, copy the impl- and test-session jsonl … 那一段）

Interfaces:

• Consumes: Task 4 installClaudeSession、claudeProjectsRoot。

• Step 1: 替换实现

把从 // Before removing the worktree, copy the impl- and test-session jsonl into 到该 if 块结束（含 catch 的 warn）整段替换为：

  // 删 worktree 前把实施/测试会话整包（jsonl + 子目录）搬到主仓库 projects 目录，
  // 并清掉 worktree 侧副本：新版 claude 遇到重复 sid 会拒绝 resume。
  if ((implementSessionId || testSessionId) && worktreePath) {
    const worktreeAbs = resolveWorktreePath(worktreePath, workspaceRoot)
    const srcProjectsDir = projectsDirFor(worktreeAbs)
    const dstProjectsDir = projectsDirFor(workspaceRoot)
    for (const sid of [implementSessionId, testSessionId]) {
      if (typeof sid !== 'string' || sid.length === 0)
        continue
      try {
        await installClaudeSession({ sid, srcDir: srcProjectsDir, dstProjectsDir, projectsRoot: claudeProjectsRoot() })
        logger.add({ level: 'info', source: 'panel', message: `cc 会话 ${sid} 已搬到主仓库 projects 目录 (issue #${issueNumber})` })
      }
      catch (err) {
        logger.add({
          level: 'warn',
          source: 'panel',
          message: `搬迁 cc 会话 ${sid} 失败 (issue #${issueNumber})，worktree 清理仍继续`,
          details: err instanceof Error ? err.message : String(err),
        })
      }
    }
  }

import：import { claudeProjectsRoot, installClaudeSession } from '../../cc/sessionBundle'。若 fs/path 因此在该文件无其它引用，保留（文件其它地方仍在用）。

• Step 2: typecheck + lint + 提交

Run: pnpm typecheck && pnpm lint && pnpm test Expected: PASS

git commit -m "🐛 fix(vscode): 完成列归档会话改为整包搬迁并清理重复 sid"

Task 11: webview：状态、按钮、选人弹窗、角标

Files:

• Create: webview-ui/src/components/HandoffModal.tsx
• Modify: webview-ui/src/hooks/useIssues.ts
• Modify: webview-ui/src/App.tsx:340-380, 444-462
• Modify: webview-ui/src/components/BottomTabs.tsx:36-60, 120-140
• Modify: webview-ui/src/components/IssueDetailPanel.tsx:20-93, 574-608
• Modify: webview-ui/src/components/IssueCard.tsx
• Modify: webview-ui/src/components/KanbanBoard.tsx / KanbanColumn.tsx（若 IssueCard 由它们渲染，无需传新 prop——角标直接读 issue.handoffAttachmentId）

Interfaces:

• Consumes: Task 1 类型与消息、Task 9 消息。

• Produces（useIssues 返回对象新增）：me: string | undefined、handoffUsers: { issueNumber: number, users: string[] } | null、requestHandoffUsers(issueNumber)、startHandoff(issueNumber, to)、acceptHandoff(issueNumber)、isHandoffRunning(issueNumber)。

• Step 1: useIssues

在 useIssues.ts 状态区加：

  const [me, setMe] = useState<string | undefined>(undefined)
  const [handoffUsers, setHandoffUsers] = useState<{ issueNumber: number, users: string[] } | null>(null)
  const handoffRunningRef = useRef<Set<number>>(new Set())
  const [handoffRunning, setHandoffRunning] = useState<Set<number>>(new Set())

回调：

  const requestHandoffUsers = useCallback((issueNumber: number): void => {
    setHandoffUsers(null)
    postMessage({ type: 'handoff/users', issueNumber })
  }, [])

  const markHandoffRunning = useCallback((issueNumber: number, running: boolean): void => {
    if (running)
      handoffRunningRef.current.add(issueNumber)
    else
      handoffRunningRef.current.delete(issueNumber)
    setHandoffRunning(new Set(handoffRunningRef.current))
  }, [])

  const startHandoff = useCallback((issueNumber: number, to: string): void => {
    if (handoffRunningRef.current.has(issueNumber))
      return
    markHandoffRunning(issueNumber, true)
    postMessage({ type: 'handoff/start', issueNumber, to })
  }, [markHandoffRunning])

  const acceptHandoff = useCallback((issueNumber: number): void => {
    if (handoffRunningRef.current.has(issueNumber))
      return
    markHandoffRunning(issueNumber, true)
    postMessage({ type: 'handoff/accept', issueNumber })
  }, [markHandoffRunning])

  const isHandoffRunning = useCallback((issueNumber: number): boolean => handoffRunning.has(issueNumber), [handoffRunning])

onMessage switch：issues/update 分支加 setMe(msg.me)；新增：

        case 'handoff/users-result':
          setHandoffUsers({ issueNumber: msg.issueNumber, users: msg.users })
          break
        case 'handoff/done':
          markHandoffRunning(msg.issueNumber, false)
          break

useEffect 依赖数组加 markHandoffRunning。返回对象加 me, handoffUsers, requestHandoffUsers, startHandoff, acceptHandoff, isHandoffRunning。

• Step 2: HandoffModal

webview-ui/src/components/HandoffModal.tsx：

import { useEffect, useState } from 'react'
import { Loader2, X } from 'lucide-react'
import { SelectMenu } from './ui/select-menu'

interface Props {
  open: boolean
  issueNumber: number | null
  /** null = 候选列表还在加载 */
  users: string[] | null
  onCancel: () => void
  onSubmit: (issueNumber: number, to: string) => void
}

export function HandoffModal({ open, issueNumber, users, onCancel, onSubmit }: Props) {
  const [to, setTo] = useState<string>('')

  useEffect(() => {
    if (!open) {
      setTo('')
      return
    }
    function handleKey(e: KeyboardEvent): void {
      if (e.key === 'Escape')
        onCancel()
    }
    document.addEventListener('keydown', handleKey)
    return () => document.removeEventListener('keydown', handleKey)
  }, [open, onCancel])

  useEffect(() => {
    if (users && users.length > 0 && !to)
      setTo(users[0])
  }, [users, to])

  if (!open || issueNumber === null)
    return null

  return (
    <div className="fixed inset-0 z-50 flex items-center justify-center bg-black/60">

      >
        <div className="mb-3 flex items-center">
          <h2 className="flex-1 font-medium">

          </h2>
          <button type="button" onClick={onCancel} aria-label="关闭" className="rounded p-1 hover:bg-white/10">
            <X className="size-4" />
          </button>
        </div>
        <p className="mb-3 text-xs opacity-70">
          会把本机的 worktree 删除、会话记录打包挂到工单附件，并把工单指派给对方。移交前分支必须已全部 push。
        </p>
        {users === null
          ? (
              <div className="flex items-center gap-2 text-xs opacity-70">
                <Loader2 className="size-3.5 animate-spin" />
                读取可指派用户…
              </div>
            )
          : users.length === 0
            ? <div className="text-xs text-red-400">没有可指派的其他用户</div>
            : (
                <SelectMenu
                  value={to}
                  options={users.map(u => ({ value: u, label: u }))}
                  onChange={setTo}
                />
              )}
        <div className="mt-4 flex justify-end gap-2">
          <button type="button" onClick={onCancel} className="rounded border border-[var(--vscode-panel-border)] px-3 py-1 text-xs hover:bg-white/10">
            取消
          </button>
          <button
            type="button"
            disabled={!to}
            onClick={() => onSubmit(issueNumber, to)}
            className="rounded bg-[var(--vscode-button-background)] px-3 py-1 text-xs text-[var(--vscode-button-foreground)] disabled:opacity-50"
          >
            移交
          </button>
        </div>
      </div>
    </div>
  )
}

SelectMenu 的 props 为 { value: string, options: SelectMenuOption[], onChange: (value: string) => void }（webview-ui/src/components/ui/select-menu.tsx:13-16）；SelectMenuOption 的第二个字段名以该文件 :7-11 为准（label 或 name），按实际写。

• Step 3: IssueDetailPanel 按钮

Props 加：

  /** 当前 Gitea login；undefined = 身份未知（接管按钮不显示）。 */
  me?: string
  onStartHandoff: (issueNumber: number) => void
  onAcceptHandoff: (issueNumber: number) => void
  isHandoffRunning: (issueNumber: number) => boolean

解构处加三个回调与 me。头部 issue.source !== 'youtrack' 的 fragment 内、「重置为待办」按钮之前加：

            {issue.handoffAttachmentId && me !== undefined && (issue.assignees ?? []).includes(me) && (
              <button
                type="button"

            {issue.handoffAttachmentId && !(me !== undefined && (issue.assignees ?? []).includes(me)) && (
              <span className="inline-flex shrink-0 items-center rounded border border-[var(--vscode-panel-border)] px-1.5 py-0.5 text-[10px] opacity-70" title={`${issue.handoffFrom ?? '?'} 已移交，等待 ${(issue.assignees ?? []).join(', ') || '?'} 接管`}>
                待接管
              </span>
            )}

从 lucide-react 追加 import ArrowRightLeft, Download, Loader2（已 import 的不重复）。

• Step 4: BottomTabs 透传

Props 接口加 me?: string、onStartHandoff、onAcceptHandoff、isHandoffRunning（类型同上）；渲染 IssueDetailPanel 处透传四个。

• Step 5: App.tsx 接线 + 挂 modal

从 useIssues() 解构出 me, handoffUsers, requestHandoffUsers, startHandoff, acceptHandoff, isHandoffRunning。加状态 const [handoffIssue, setHandoffIssue] = useState<number | null>(null)。

BottomTabs 加：

                me={me}
                onStartHandoff={(n) => { setHandoffIssue(n); requestHandoffUsers(n) }}
                onAcceptHandoff={acceptHandoff}
                isHandoffRunning={isHandoffRunning}

在 <NewIssueModal …/> 旁挂：

      <HandoffModal
        open={handoffIssue !== null}
        issueNumber={handoffIssue}
        users={handoffUsers && handoffUsers.issueNumber === handoffIssue ? handoffUsers.users : null}
        onCancel={() => setHandoffIssue(null)}
        onSubmit={(n, to) => { startHandoff(n, to); setHandoffIssue(null) }}
      />

• Step 6: IssueCard 角标

IssueCard.tsx 在 locked 图标之后（同级）加：

        {issue.handoffAttachmentId
          ? (
              <span
                className="absolute bottom-1 right-1.5 rounded border border-blue-400/50 bg-blue-400/10 px-1 text-[9px] text-blue-400"
                title={`${issue.handoffFrom ?? '?'} 已移交，待接管`}
              >
                待接管
              </span>
            )
          : null}

• Step 7: typecheck + lint + 提交

Run: pnpm typecheck && pnpm lint Expected: PASS

git add webview-ui/src
git commit -m "✨ feat(vscode): webview 移交/接管按钮、选人弹窗与待接管角标"

Task 12: README、版本、打包、安装、spx 重装

Files:

• Modify: README.md（工作流章节、state JSON 字段表、面板「工单 tab」段）

• Modify: package.json:5（0.2.95 → 0.2.96）

• Step 1: README

「工作流」列表第 6 条「回退」后加第 7 条：

7. **移交**：工单 tab 头部「移交」→ 选同事。插件校验 worktree 已全部 push，关掉该工单的终端，把头脑风暴 / 实施 / 测试的 claude 会话（jsonl + 子目录）和 codex 审查会话打成 `spx-handoff-issue-N.tgz` 挂到工单附件，写 `handoffAttachmentId` / `handoffFrom`，把工单指派给对方，最后删本机 worktree 与本地分支（远端分支保留）。对方看板上该卡显示「待接管」，工单 tab 点「接管」：从 origin 重建 worktree（`git worktree add -B <branch> … origin/<branch>`）、把会话文件装到本机 `~/.claude/projects/` 对应目录（先清同 sid 副本）与 `~/.codex/sessions/`、写本机字段、清移交字段并删附件。之后 resume / 合并 / 冲突解决 / 测试与本机实施的工单无异。

state JSON 字段表加两行：

| `handoffAttachmentId` / `handoffFrom` | 移交中：会话包附件 id 与发起人；接管后清空 |

「工单 tab」段落的顶部按钮列表加「移交 / 接管」。

「环境要求」表 git 行说明末尾加「、tar（移交打包）」。

• Step 2: 版本号与打包

package.json 的 "version": "0.2.95" → "0.2.96"。

Run: pnpm test && pnpm lint && pnpm typecheck && pnpm ext:package Expected: 生成 superpowers-vscode-clurdra-0.2.96.vsix。

• Step 3: 安装本机 + 重装 spx

Run:

code --install-extension superpowers-vscode-clurdra-0.2.96.vsix --force --profile augment
cd cli && make install && spx --help | head -3

Expected: 扩展安装成功；~/.local/bin/spx 为带新 schema 的版本。

• Step 4: 提交

git add README.md package.json
git commit -m "🔖 chore(vscode): bump 0.2.96，README 补移交/接管"

Task 13: 端到端验证（手动）

Files: 无代码改动；问题回到对应 Task 修。

• Step 1: 双窗口准备

同一台机器开两个 VS Code 窗口指向同一仓库的两个 clone（或用 dse / m1max 其中一台作为接管方），分别配置两个不同 Gitea 账号的 token（git config user.email 与 Gitea 邮箱一致）。两边都装 0.2.96 与新 spx。

• Step 2: 移交

在窗口 A：挑一个进行中的工单（有 worktree、实施会话），确保 git status 干净且已 push。工单 tab 点「移交」→ 选 B 账号 → 确认。 Expected：spinner toast → 成功 toast；A 的工单 tab 会话 id / 工作树行清空；Gitea 工单附件里出现 spx-handoff-issue-N.tgz；state 评论含 handoffAttachmentId / handoffFrom；assignee 变为 B；A 本机 worktree 目录消失、git branch 无该 feature 分支、git ls-remote origin <branch> 仍在。

• Step 3: 接管

在窗口 B：看板卡片出现「待接管」角标（webhook 指派事件触发刷新；否则点刷新）。工单 tab 点「接管」。 Expected：成功 toast 含 worktree 路径；工作树行可双击打开；会话 id 行双击能 claude --resume 起同事的实施会话且历史完整；ls ~/.claude/projects/*/<sid>.jsonl 只有一份；Gitea 附件已删除；state 评论两个 handoff 字段为空。

• Step 4: 后续流程

在窗口 B 把工单拖到「完成」：PR 合并（或制造冲突验证 issue-N-冲突解决 会话能在重建的 worktree 里启动）。 Expected：与本机实施的工单行为一致。

• Step 5: 失败路径

在 A 上对一个有未提交改动的 worktree 点「移交」。 Expected：toast「工作区有未提交改动…」，什么都没改（附件、assignee、本机状态均不变）。
