test(markdown): make disappearing-upload-file cases deterministic

The three temporary_file_disappears_before_stat subtests raced a polling goroutine against a 16MB write, hoping the removal landed between write and stat. On fast CI runners the window is routinely missed, failing Coverage jobs on main and every open PR. Replace the race with an injectable markdownStatUpload seam that removes the file before delegating to os.Stat.

 ## [Unreleased]

+## [1.0.55-beta.2] - 2026-07-23
+
+This beta validates Wukong capability parity across Chat, Contacts, documents,
+Drive, Markdown, and Todos, together with faster guarded releases and legacy
+authentication migration.
+
+### Added
+
+- **Chat editing and group management** — adds `chat message edit`, conversation-category lookups through `chat category list-by-conv` and `chat category batch-info`, and the confirmed, irreversible `chat group upgrade-to-external` flow.
+- **Contact maintenance commands** — adds `contact user update`, `contact user update-self`, `contact dept create`, `contact dept update`, and `contact account update`, all with guarded write behavior.
+- **Markdown file workflows** — adds the `markdown` product with `fetch`, `create`, `overwrite`, and `patch` commands for Drive-native `.md` files, including explicit routing, dry-run previews, and confirmation for destructive writes.
+- **Todo labels** — adds `todo tag add`, `delete`, `update`, `list`, and `create`.
+
+### Changed
+
+- **Faster guarded releases** — trusts an independently revalidated, exact `CHANGELOG.md`-only successor of an already admitted `main` commit, runs cloud planning alongside governance, and executes sealed-release automation, compatibility, and multi-profile validation in parallel with artifact compilation. Normal cloud publication no longer requires an unshareable local packaging preflight.
+- **Scoped document reads and group mentions** — `doc read --content-format jsonml` can return `outline`, `range`, `section`, or custom-tag fragments with depth and block-boundary controls; document comment create, reply, and update can mention groups through `--mentioned-open-conversation-id`.
+- **Drive overwrite uploads** — `drive upload --node <fileId>` can replace an existing Drive or document-space file, is mutually exclusive with `--folder`, supports dry-run, and requires confirmation before writing.
+- **Chat nickname clearing and cross-organization todos** — omitting `--nick` from `chat group update-nick` now clears the current user's group nickname, while `todo task list --query-all` queries todos across organizations.
+
+### Fixed
+
+- **Legacy authentication compatibility** (#756) — migrates pre-v1.0.53 global and organization-scoped login state into the identity-aware token store, including all legacy organizations, while keeping unresolved accounts isolated from exact `corpId:userId` credentials so external or no-directory identities can complete login without borrowing another user's token.
+
+## [1.0.55-beta.1] - 2026-07-23
+
+This beta validates MCP Market URL resolution, the supported Wukong local-file
+send path after retiring the legacy credential-based media upload command from
+discovery, and reliable message-read rendering for rich content, forwarded
+records, encrypted messages, and media-download ID aliases.
+
+### Added
+
+- **MCP URL resolution** — adds `dws mcp url get <mcpId>` for resolving a DingTalk MCP Market ID to the current user and organization scoped Streamable HTTP URL, while keeping the helper-only `mcp-meta` endpoint out of the public product command surface.
+
+### Changed
+
+- **Chat local-file sending** — hides the open-source-only `chat media upload` compatibility command from Help, Schema, and bundled Skills, and removes its legacy AppKey/AppSecret OAPI path. Historical argv still receives an actionable migration error. Send local images and files through `chat message send --msg-type file --file-path`; callers that already hold a mediaId may continue to use `--msg-type image --media-id`.
+
 ### Fixed

 - **Message-read shortcut projection** (#706) — the message-list shortcuts (`chat +chat-messages` / `+messages-list` / `+messages-list-direct` / `+at-me` / `+search-msg` / `+thread-replies`) now render card and out-of-office rich-content JSON as readable text (without ever rewriting ordinary text that merely embeds a JSON fragment), expand a forwarded chat record's nested `forwardMessages` instead of collapsing to a "[卡片]" summary, and mark undecryptable encrypted card messages as `[加密消息]`; the speaker is read from the bare `sender` key, nested `{name:…}` sender objects yield their display name, and the literal string `"null"` is treated as absent. Shared projection helpers now live in `internal/shortcut/chatmsg`. `chat message download-media` also gains `--msg-id` / `--open-message-id` aliases for its `--message-id` flag so agents copying the `openMessageId`/`msgId` output field no longer hit "unknown flag".

 `plan` 是纯只读操作，不创建 tag、预留版本号或生成包。CHANGELOG 合入期间若另一个发布先占用了该版本，`publish` 会重新分配并因 CHANGELOG 章节不匹配而拒绝，需要重新 plan。`publish` 会先再次确认 dispatch SHA 仍是当前 `main`、Code Admission 和平台治理均通过，再由唯一的 write job 使用 GitHub API 原子创建 annotated tag；同一次 run 随即进入既有的跨平台构建、GitHub/npm、可选 OSS/Gitee 发布和 Homebrew PR DAG。内置 `GITHUB_TOKEN` 创建的 tag 不依赖第二条 workflow 被再次触发。

+为缩短封板前后的关键路径，`publish` 的只读版本规划会与平台治理检查并行，seal 仍严格等待二者成功；plan 在 candidate annotated tag 上验证过的 contract 和 stable/beta baseline 会绑定进 seal，并由 seal 后的 tag authority 检查复用。Code Admission 状态与 immutable-releases 治理仍会在 seal 后再次读取，避免 preflight 与发布之间的状态变化被忽略。随后三类只读门禁（release automation、命令兼容性、multi-profile E2E）与 GoReleaser 构建并行；Node/archive 等仅供后处理使用的工具也延后到构建完成后安装。并行和已验证结果复用只改变调度，不降低发布门禁：任何一条验证失败都会阻止 GitHub Release、npm、镜像和 Homebrew 发布，delivery proof 也要求三条验证 job 全部成功。

 OSS 镜像默认不参与发布 DAG，适用于尚未创建 Bucket 的仓库。云端封板会把当时的仓库变量 `ENABLE_OSS_MIRROR=true` 记录为不可变 tag 元数据 `OSS-Mirror: enabled`，否则记录为 `deferred`；后续发布和撤回只读取该 sealed policy，不读取变量的当前值。`enabled` 继续对缺失凭据、无效 Bucket、上传、pointer 和撤回失败保持 fail-closed；`deferred` 明确跳过不存在的渠道。为避免补发后撤回遗漏，deferred 版本暂不接受 `repair_oss_version`，启用 OSS 只影响后续新 tag，直到补齐可审计的不可变 repair 证明。

修雨	735ef6b3f2	test(markdown): make disappearing-upload-file cases deterministic The three temporary_file_disappears_before_stat subtests raced a polling goroutine against a 16MB write, hoping the removal landed between write and stat. On fast CI runners the window is routinely missed, failing Coverage jobs on main and every open PR. Replace the race with an injectable markdownStatUpload seam that removes the file before delegating to os.Stat.	2026-07-24 11:12:52 +08:00
