 ### Changed
 
+- **Relaxed stable promotion contract** — a stable release still requires a delivered, non-withdrawn beta baseline in its commit history, but no longer requires a byte-identical tree with that beta; reviewed commits merged to `main` after the beta can now ship in the stable release. Local releases now accept any sealed commit contained in `main` history and push only the release tag, so `main` is never frozen during the beta-to-stable window.
+
+## [1.0.53] - 2026-07-21
+
+This release promotes the sealed `v1.0.53-beta.7` contents to stable. It adds enterprise onboarding, declarative shortcuts, Sheet/Aitable writes, multi-account profiles, and broader personal IM events, while hardening authentication and the guarded release path.
+
+### Added
+
+- **Enterprise and office command coverage** — adds enterprise creation, employee invitation, and account provisioning commands; 366 declarative service shortcuts; Sheet import commands; and Aitable workflow create/update support with reviewed Schema contracts.
+- **Multiple accounts in one DingTalk organization** — profiles can distinguish accounts by organization and user, select them explicitly, and log out one account or an entire organization without overwriting another account's credentials.
+- **Expanded personal IM event subscriptions** (#651) — adds read-receipt, recall, and reaction events for one-to-one and group chats, plus specified-sender subscriptions by staff ID or OpenDingTalk ID.
+- **Official multi-platform Homebrew channel** — ships separate stable and keg-only beta Formulae for macOS and Linux across amd64 and arm64, with isolated update PRs.
+
+### Changed
+
+- **Personal event output contract** (#651) — `event consume` now emits event-specific top-level structured fields; scripts that consumed the former transport envelope must use the flat fields or select `-f raw`, while `--debug-raw-events` retains the diagnostic envelope.
+- **Guarded release lifecycle** — beta/stable publication now uses explicit promotion, immutable delivery proofs, protected recovery, and tag-bound optional OSS policy; an unprovisioned OSS mirror is sealed as `deferred` so GitHub, npm, and Homebrew are not blocked.
+
+### Fixed
+
+- **Authentication and credential reliability** — organization-policy denials stop before mutation or polling, long-running clients reload and refresh access tokens consistently, concurrent credential writes are atomic, and Windows portable-auth commands fail before reading or writing unsupported credential bundles.
+- **Command validation and compatibility** — invalid Sheet/task targets fail locally, IM shortcuts preserve AI-tag and alias compatibility, and Aitable import uploads require and forward a positive file size.
+- **Release publication reliability** — GitHub draft publication is bound to one verified release ID and exact assets, preflight uses isolated installer worktrees, guarded local tags remain compatible, cloud planning fingerprints the actual allocated release refs, and npm channel verification waits for bounded registry propagation without moving tags.
+
+## [1.0.53-beta.7] - 2026-07-21
+
+This beta validates bounded npm channel verification after registry publication.
+
+### Fixed
+
+- **npm dist-tag eventual consistency** — Release delivery now tolerates a briefly stale `latest` or `beta` read after publishing by retrying only when npm reports a valid older version. Registry errors, invalid or incomparable tags, and channels that never converge still fail closed without moving any tag during verification.
+
+## [1.0.53-beta.6] - 2026-07-21
+
+This beta validates guarded local release compatibility and tag-bound OSS deferral so an unprovisioned mirror cannot block the primary release channels.
+
+### Changed
+
+- **Tag-bound optional OSS release mirror** — Official cloud Release runs no longer block GitHub, npm, and Homebrew delivery when an OSS bucket has not been provisioned. Cloud tags immutably record `OSS-Mirror: enabled|deferred`; publication, repair, and withdrawal consume that sealed policy instead of the current repository variable. Enabled releases remain fail-closed, while deferred releases skip the nonexistent channel and cannot be backfilled without a future audited repair proof.
+
+### Fixed
+
+- **Guarded local release compatibility** — The tag-push Release workflow now accepts the `Channel`-only annotated tags created by the guarded local release entry while continuing to reject any partial cloud-only seal metadata.
+- **Cloud release tag allocation fingerprint** — Release planning now fingerprints the actual `v*` and `withdrawn/v*` refs fetched from GitHub, matching the seal job's API view instead of hashing an empty non-wildcard ref prefix and rejecting every publish before tag creation.
+
+## [1.0.53-beta.5] - 2026-07-21
+
+This beta validates long-running access-token recovery and the faster, recoverable guarded release path introduced after v1.0.53-beta.4.
+
+### Changed
+
 - **Fast guarded beta and stable releases** — successful local release checks now leave a six-hour proof bound to the exact version, commit, repository identity, remote `main`, and stable baseline, so the subsequent guarded `--publish` invocation revalidates authority without repeating tests and packaging. A default-branch governance smoke uses the same dedicated immutable-release credential as the tag workflow before any tag is allocated.
 - **Protected existing-tag recovery** — `dws-release recover <version>` can resume a failed, unpublished annotated tag through the normal contract, build, Developer ID signing, immutable GitHub Release, Homebrew, npm, and OSS jobs. Recovery requires the exact tag object, peeled commit, failed tag-push run, typed version confirmation, and the protected `release-recovery` environment; successful runs are accepted as future beta/stable delivery evidence.
 
 ### Fixed
 
+- **Long-running event authentication recovery** — personal and portal event streams resolve the current access token for every ticket request, refresh a server-rejected token with compare-and-refresh semantics, and reconnect with backoff when refresh is temporarily blocked by network failures, rate limits, or 5xx responses.
 - **Consistent access-token caching and errors** — runtime, recovery, Skill, PAT polling, and personal/portal event clients now resolve user access tokens through one expiry- and publication-aware manager, so long-running processes reload rotated credentials while keychain, refresh, parse, permission, and cancellation failures remain observable instead of being collapsed into “not authenticated.”
 - **Tag-push GitHub Release publication** — Draft publication now locks one GitHub Release database ID, verifies its exact tag, channel, notes, recovery marker, asset set, and uploaded bytes, then publishes and rechecks that same ID as immutable. Recovery runs use the trusted default-branch release helpers instead of the sealed tag's historical scripts, fixing the Draft-only `GET /releases/tags/{tag}` 404 without allowing the release identity to drift during recovery.
 - **Release preflight reliability** — source-mode installer tests now use isolated temporary checkouts and HOME directories instead of overwriting and deleting the real repository `dws` binary, release preflight explicitly rebuilds before policy checks, and the full-suite runner gives the growing script package a non-flaky five-minute per-suite budget.

-## 日常只用一个入口
+## 推荐入口：GitHub 云端发布
+
+任何具有仓库写权限、因而可以手动运行 Actions workflow 的成员，都可以基于当时最新的 `main` 发起发布：
+
+1. 在 GitHub Actions 打开 `Release`，选择 `Run workflow`，分支必须是默认分支 `main`。
+2. `release_operation=plan`，选择 `release_channel=beta|stable`；仅在开始新 beta 线时选择 `release_bump=patch|minor|major`。
+3. workflow summary 会给出唯一的下一版本。把对应的精确 `CHANGELOG.md` 章节通过 PR 合入 `main`。
+4. 再次运行，改为 `release_operation=publish`，并输入 `PUBLISH beta` 或 `PUBLISH stable`。
+
+`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。
+
+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。
+
+## 自动版本规则
+
+- beta：如果存在尚未封正式版的最高版本线，自动取 `beta.N+1`；否则从最新已分配正式版按所选 patch/minor/major 开新线并取 `beta.1`。
+- stable：先锁定最高开放版本线上的最新已分配 beta，再要求它已成功交付且未撤回；不会跳过失败/撤回的最新 beta 去选择更早版本。正式版 core 与该 beta 完全相同。
+- `vX.Y.Z`、`vX.Y.Z-beta.N` 一经分配就永久占用。撤回时创建 `withdrawn/v...` 墓碑，原编号永不复用。
+- 例如撤回 `v1.0.53-beta.5` 后，下一 beta 是 `v1.0.53-beta.6`；撤回正式版 `v1.0.53` 后，下一 patch 修复线是 `v1.0.54-beta.1`，验证后再发布 `v1.0.54`。
+- 如果最新 beta 已撤回，禁止直接用更早 beta 晋级正式版；必须先构建下一个 beta。
+
+## 全平台撤回与回滚
+
+已公开版本出现问题时，在 GitHub Actions 运行 `Withdraw release`，分支必须选择当前默认分支 `main`，并填写：
+
+- `version`：精确版本，例如 `v1.0.53` 或 `v1.0.53-beta.5`。
+- `reason`：8–300 字符的单行公开原因。
+- `confirmation`：精确输入 `WITHDRAW <version>`，例如 `WITHDRAW v1.0.53`。
+
+该 workflow 使用与发布相同的串行 publication lock，并进入受保护的 `release-withdrawal` environment。它只接受已经由 Release workflow 完整交付的 public immutable release，自动选择同一渠道中最新的、更早且未撤回的完整版本作为回退目标，然后按以下顺序执行：
+
+1. 先创建永久 annotated tag `withdrawn/<version>`，记录原 tag object、commit、原因、申请人和 workflow run。这个墓碑是版本号永久占用记录，永不移动、永不删除。
+2. 先验证 Homebrew Formula；若它仍指向问题版本，先创建回退 PR，再继续其他渠道撤回。这样 PR 创建失败时只留下可安全续跑的墓碑，不会先造成渠道分裂。若 Formula 尚未指向问题版本或已经处于安全版本，则直接校验。
+3. GitHub Release 先标记为 withdrawn；npm 精确版本执行 `deprecate`，并把 `latest` / `beta` dist-tag 回退；只有目标 tag 封存了 `OSS-Mirror: enabled` 时，OSS 才会先补齐回退版本资产，再移动 `latest.txt` / `beta.txt` 并删除问题版本目录；启用 Gitee 时同样先补齐回退 Release，再删除问题 Release 和 tag。
+4. npm 以及目标 tag 启用或发布时配置的镜像渠道均已验证安全后，删除 GitHub 上的问题 Release 和原 `v...` tag，并验证 `/releases/latest` 对正式版回到安全版本。若本次创建了 Homebrew PR，run 最后故意保持失败，直到另一名维护者审核合入；合入后，从新的 `main` 使用完全相同的 version、reason 和 confirmation 重跑并完成。永久 `withdrawn/v...` 墓碑始终保留。
+
+GitHub、npm、OSS、Gitee 和 Homebrew 的“回滚”指新的安装、升级和渠道解析不再拿到问题版本。已经装到用户电脑上的二进制无法被服务端强制降级；用户必须重新安装回退版本、安装后续修复版，或使用 CLI 自带的本地 rollback 能力。npm 不执行 `unpublish`：问题版本保留明确的弃用警告，但 `latest` / `beta` 不再指向它；即使 registry 允许删除，已发布过的版本号也不会重新使用。
+
+撤回前必须存在同一渠道中更早、完整交付且未撤回的安全版本；若目标是该渠道第一个版本、没有安全候选，workflow 会在创建墓碑或修改任何渠道前 fail closed，需要先决定明确的替代策略。CLI 本地 rollback 也只有在本机仍保留上一次升级备份时可用。
+
+撤回以“精确版本”为单位，不会因为正式版曾由某个 beta 晋级就隐式级联修改另一个渠道。若同一缺陷同时存在于正式版及其 beta，应先撤回正式版，再撤回对应 beta，并分别使用各自的精确确认串；每次都只会把该渠道回退到自己的安全候选。
+
+撤回正式版 `v1.0.53` 后，`v1.0.53` 仍被墓碑视为已分配。下一次 patch 发布从 `v1.0.54-beta.1` 开始，验证后晋级 `v1.0.54`。撤回 `v1.0.53-beta.5` 后，同一开放版本线继续为 `v1.0.53-beta.6`；不会退回或复用 `beta.5`。

 - 日常 CI 和发布前都会对比“最新已交付正式版”的完整命令树；若长时间预检期间该 baseline 发生变化，会针对新的 baseline 重新比较。
 - GoReleaser 只构建；Darwin 重签、checksums 重算和 npm 安装验证通过后，才统一上传 GitHub Release 的最终产物。
 - 六个平台归档会逐个解包并核验二进制内嵌版本；公开资产集合、checksums 集合和 npm tarball integrity 都必须精确一致。npm tarball 固定由 npm `10.9.2` 打包，避免重跑时因 runner 自带 npm 漂移产生不同字节。

 npm 补发只允许从默认分支触发 Release workflow 的 `repair_npm_version`。它只支持启用 immutable releases 后、由本流水线成功产出的公开 immutable release：目标必须是 `main` 历史中的 annotated tag，并且同 commit 的 `Build immutable GitHub Release` job 已成功。即使后续 npm 分发失败，这个独立的产物封存边界仍可作为补发依据。补发会用目标 commit 的 npm 模板重组包，逐平台核验资产和二进制版本，再发布到隔离的 `backfill` dist-tag，不会回滚 `latest` / `beta`。历史 mutable release 不进入自动补发路径，避免把可被替换的资产带入 npm。

-Homebrew 当前只属于本机预检/手工公式通道：预检会在当前 macOS 架构真实安装，但 Release workflow 不发布 tap，CI 生成的单主机公式也不应当作 Darwin 双架构正式交付。正式自动交付范围是 GitHub Release、npm、OSS，以及显式开启时的 Gitee fallback；Homebrew 双架构 tap 发布需另立需求。
+OSS 的 `latest.txt` / `beta.txt` 是镜像频道元数据；当前仓库安装器仍主要从 GitHub/Gitee 解析版本。启用 OSS 后，发布和撤回把它作为受控分发渠道处理，保证一旦外部消费者接入该 pointer，也不会继续解析到已撤回版本；未启用时两条流程都明确跳过不存在的 OSS 渠道。
+
+Release workflow 会生成 Darwin/Linux 双架构 Formula，并分别为 stable/beta 打开 Homebrew PR；tap 的默认分支仍以独立审核合入为交付边界。撤回 workflow 使用相同模板和回退版本 checksums 打开反向 PR；问题 GitHub Release 会先被移除以阻止新安装，永久墓碑和 workflow 日志承担审计/续跑依据。

 - 必须启用 immutable releases；它只保护启用后发布的 release，因此应在第一次使用新流水线前配置。为 `v*` 增加 tag ruleset，限制创建权限，并在 release 发布前保护 tag 的短暂窗口。
+- tag ruleset 还必须覆盖 `withdrawn/v*`：只允许受保护的撤回 workflow 创建墓碑，禁止更新或删除墓碑；同时应允许 Release workflow 创建新的 `v*`，允许撤回 workflow 在全部渠道回退后删除精确的问题 `v*`。若组织级规则阻止这两个 workflow 的预期动作，发布或撤回会 fail closed，不能靠手工移动 tag 绕过。
 - 配置 `RELEASE_GOVERNANCE_TOKEN` Actions secret，只授予目标仓库 `Administration: read`；内置 `GITHUB_TOKEN` 不具备 immutable-releases API 所需的仓库治理权限。每次本地预检和 tag workflow 都使用这一个身份进行 fail-closed 验证。
+- 配置 `APPLE_CERTIFICATE_P12_BASE64`、`APPLE_CERTIFICATE_PASSWORD` 和具备发布权限的 `NPM_TOKEN`；撤回还要求该 npm 身份能够执行 `deprecate` 和修改 dist-tag。
+- 启用 OSS 镜像时，先创建有效 Bucket，再设置仓库变量 `ENABLE_OSS_MIRROR=true`，并配置 `OSS_ACCESS_KEY_ID`、`OSS_ACCESS_KEY_SECRET`、`OSS_ENDPOINT`、`OSS_BUCKET`，按需配置 `OSS_PREFIX`。启用后发布保持 fail-closed；撤回身份必须能够补齐安全版本资产、写 `latest.txt` / `beta.txt` 并删除问题版本前缀。尚未 provision Bucket 时保持该变量未设置或不等于 `true`，新 tag 会封存 `OSS-Mirror: deferred` 并跳过 OSS；该版本不能通过现有 repair 流程事后改成启用。
+- 若启用 Gitee fallback，设置 `ENABLE_GITEE_UPLOAD_FALLBACK=true`，并配置 `GITEE_TOKEN`、`GITEE_USER`、`GITEE_REPO`；该身份必须能够创建和删除目标仓库的 Release 与 tag。
 - 单独配置 `HOMEBREW_PR_TOKEN`，优先使用仅授权本仓库且具备 `Contents: write`、`Pull requests: write` 的 fine-grained PAT；若组织策略不允许该账号使用 fine-grained PAT，则回退到仅带 `public_repo` scope 的专用 classic PAT。治理预检和 tag contract 会验证 token 身份、classic scope，并用 `[skip ci]` 临时分支和 draft PR 完成真实写权限 canary，随后立即关闭 PR、删除分支；任何清理失败都会 fail closed。门禁也会拒绝与治理 token 复用。
 - 创建 `release-recovery` environment，只允许受保护分支，设置 required reviewer、禁止自审并关闭管理员绕过。workflow 会读取 environment 的 required-reviewer、prevent-self-review 和 protected-branch 规则；规则缺失时紧急恢复会失败，正常 beta/stable tag 发布不受影响。
+- 创建 `release-withdrawal` environment，只允许受保护分支，设置至少一名 required reviewer、禁止申请人自审并关闭管理员绕过。撤回 workflow 会通过 API 复核这些规则；任何一项缺失都会在触碰 npm、OSS、Gitee、Homebrew 或 GitHub Release 前失败。
+- 仓库或组织的 Actions 策略必须允许 `Release` 与 `Withdraw release` workflow 的 `GITHUB_TOKEN` 获得各 job 声明的 `contents: write`。若上述发布凭证采用 environment secret，确认 `release-withdrawal` 审批完成后能够读取撤回所需的 npm、OSS、Gitee 和 Homebrew 凭证。
