 ## [Unreleased]
 
+### 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` can resume a failed, unpublished annotated tag through the normal contract, build, Developer ID signing, immutable GitHub Release, Homebrew, npm, and OSS jobs.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
+
+- **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.
+
+## [1.0.53-beta.4] - 2026-07-17
+
+This beta validates the expanded personal IM event subscriptions and the flattened `event consume` structured output introduced after v1.0.53-beta.3.
+
 ### Added
 
+- **Expanded personal IM event subscriptions** (#651) — adds one-to-one and group events for message read receipts, recalls, and reactions; publishes the specified-sender receive event; and lets one-to-one/sender subscriptions target either a staff `--user` or an `--open-dingtalk-id`. Event Schema now exposes these alternatives through machine-readable parameter constraints.
+
+### Changed
+
+- **Personal event structured output is now flat** (#651) — `event consume` projects NDJSON/JSON/pretty/compact output into event-specific top-level DTOs, so consumers read fields such as `content`, `sender`, and `conversation_id` directly instead of parsing `.data | fromjson`. This is a breaking change for scripts using the former transport envelope; the original server payload remains available through `-f raw`, while `--debug-raw-events` preserves the full diagnostic envelope.
+
+## [1.0.53-beta.3] - 2026-07-17
+
+This beta validates multi-account profile support and the post-v1.0.53-beta.2 compatibility fixes for Windows portable authentication, IM shortcuts, and Aitable import uploads.
+
+### Added
+
+- **Multiple accounts in one DingTalk organization** — profiles are keyed by `corpId:userId`, `--profile` accepts organization IDs/names plus user IDs/names, and organization-only selection uses its explicitly remembered current account or asks for an exact account when ambiguous.
+
+### Changed
+
+- **Profile-scoped logout and consistent token storage** — `dws auth logout --profile` can remove one account or every account in an organization, while identity token slots remain the source of truth and legacy organization/global mirrors stay compatible without overwriting newer account credentials.
+
+### Fixed
+
+- **Windows portable-auth contract** — `dws auth export` and `dws auth import` now fail early without reading credentials, bundles, or writing files instead of claiming portable-bundle support for DPAPI-protected HKCU Registry credentials.
+- **IM shortcut message tags and compatibility aliases** (#646) — IM send shortcuts now add the same AI-sent marker as `chat message send` by default, support `--ai-tag=false` to opt out, and preserve compatible search, conversation-ID, and page-size aliases.
+- **Aitable import upload file-size validation** (#654) — `dws aitable import upload` and `dws aitable +import-upload` now require a positive `--file-size` and always send it to the upload-preparation API, preventing invalid requests without the actual file size.
+
+## [1.0.53-beta.2] - 2026-07-16
+
+This beta validates the accumulated post-v1.0.52 command surface, release automation, and runtime hardening changes, including enterprise contact onboarding, declarative shortcuts, Sheet/Aitable writes, multi-platform Homebrew formulas, and credential and target-validation fixes.
+
+### Added
+
+- **Contact enterprise onboarding commands** — adds `contact org create`, `contact user invite`, and `contact account create` for creating a DingTalk enterprise, inviting an employee by mobile, and provisioning an enterprise login account, with reviewed Schema contracts and mono/multi Skill routing.
 - **Declarative shortcut commands** (#592) — adds 366 `dws <service> +<command>` shortcuts across 16 services, including one-to-one MCP wrappers and multi-step smart workflows. Shortcuts publish stable Agent-visible contracts with named flags, validation and confirmation metadata, dry-run protection for writes, catalog/help routing, and optional local YAML extensions and usage recording.
 - **Sheet imports and Aitable workflow writes** (#624) — adds `dws sheet import` / `sheet import create` for converting local xlsx/xls files into new online sheets, `sheet import get` for polling import tasks, and `dws aitable workflow create/update` for applying validated `workflow-dsl/v1` definitions, with matching reviewed Agent Schema and bundled Skill guidance.
 - **Official multi-platform Homebrew channel** — stable `Formula/dingtalk-workspace-cli.rb` and keg-only `Formula/dingtalk-workspace-cli-beta.rb` live in this repository and select signed macOS Intel/Apple Silicon or Linux amd64/arm64 artifacts at install time. Stable and beta releases open isolated Formula update PRs after final artifact signing, so beta never replaces the stable Formula. Agent Skills stay under `pkgshare` without mutating the user's home directory, and both tracks are covered by the six-channel post-release verifier.
 
+### Changed
+
+- **Guarded prerelease and stable automation** — adds the guided `dws-release` entry for one-command CHANGELOG preparation, validation-only and annotated-tag publication flows; promotes only an explicitly validated beta; verifies command-tree compatibility and all six packaged binaries; and serializes immutable GitHub Release, npm channel, OSS, Homebrew, and optional Gitee delivery with fail-closed recovery checks.
+- **Reviewed historical release recovery proofs** — release preflight can recognize an explicitly pinned successful recovery delivery for a historical stable tag while still rejecting arbitrary workflow dispatches, mismatched commits, and incomplete release, signing, or publication jobs.
+
+### Fixed
+
+- **PAT organization-policy denials stop immediately** — `PAT_ORG_POLICY_DENIED` now remains terminal even if a backend also returns `flowId`, authorization URLs, or client credentials; the CLI does not mutate process credentials, open a browser, poll, or retry until an organization administrator changes the policy.
+- **Sheet and task invalid-target failures** — `sheet range read/get` now rejects a null cell-info response instead of printing `null` and exiting successfully, while task completion and attachment listing verify that a task exists before calling lenient backend endpoints. Attachment listing is also published through Runtime Schema for schema-first Agent discovery.
+- **Concurrent credential writes and reentrant CLI execution** — secure-token writers now use isolated, exclusive temporary files before atomic replacement so concurrent processes cannot remove each other's in-flight data, and repeated in-process CLI runs close the previous file logger before replacing it instead of retaining the prior log-file handle.
+

 - **Command-surface regression tests** — root-command tests now cover real `contact label`/`role` dry-runs, hidden top-level contact compatibility entries, `chat file upload` downline behavior, and `calendar event list --dry-run`.

+`dws` can stay logged in to several DingTalk accounts at once, including multiple accounts in the same organization. A profile is uniquely identified by `corpId:userId`; the current profile decides which identity a command runs as.
 
 ```bash
-dws auth login                              # log in to another org → adds a profile (first login becomes the primary)
-dws profile list                            # list logged-in orgs (primary / current marker, status)
-dws profile switch <name|corpId>            # switch the default org (use - to toggle back to the previous one)
-dws --profile <name|corpId> contact user search --query "..."   # run one command against a specific org, without changing the default
+dws auth login                              # add or refresh one account
+dws profile list                            # list every logged-in account
+dws profile switch <corpId:userId>          # persistently switch; use - to toggle back
+dws profile switch "<corpName>:<userName>"  # friendly input; names must be unique
+dws --profile <corpId> contact user search --query "..."        # use that org's explicitly recorded current account
+dws --profile <corpId:userId> contact user search --query "..." # use one exact account without changing the default
 ```
 
-Cross-org reads are orchestrated by the agent rather than a built-in `--all-orgs`: list the profiles, run the query per org with `--profile`, then merge. Writes default to the current org only — confirm the target org before writing across orgs.
+Selectors support `corpId:userId`, `corpId:userName`, `corpName:userId`, and `corpName:userName`. Friendly names are input aliases only; use the stable `profile` value returned by `profile list` for automation. Duplicate organization or account names fail with explicit `corpId:userId` candidates. If an organization has multiple accounts but no recorded current account, `--profile <corpId>` fails instead of choosing the first or most recently used account.
+
+`currentProfile`, `previousProfile`, and per-organization defaults are stored as exact identities. `primaryProfile` remains in JSON only for compatibility and is not used for selection. `profile list` reads status and expiry from each real identity Token without refreshing it. `auth logout --profile <corpId>` removes all local accounts in that organization; an exact selector or local profile name removes one account.
+
+Cross-org reads are orchestrated by the agent rather than a built-in `--all-orgs`: list profiles, group by `corpId`, and use the unique `isOrgCurrent=true` account for each organization. If a multi-account organization has no default, ask the user to choose an account first. Writes default to the current account — confirm both organization and account before cross-org writes.

 ## Homebrew Formula PR Automation
 
 Official tag releases require the repository Actions secret

-allow fine-grained personal access tokens to target this repository, so use a
-classic personal access token owned by a maintainer or release-bot account with

+maintainer or release-bot account, limited to this repository with

+that account from targeting the repository, use a dedicated classic token with
 only the `public_repo` scope. Do not reuse a broad developer token.

+Store the dedicated token as the `HOMEBREW_PR_TOKEN` repository Actions secret
+and rotate it before its configured expiration. Replace it immediately if it is
+exposed, its owner loses repository access, or the release-bot ownership
+changes. The Release workflow uses this
 dedicated token only to push an `automation/homebrew-*` branch and open the
 stable or beta Formula PR. It does not push Formula changes directly to `main`.
+The default-branch governance preflight and every tag contract authenticate the
+token before publication, reject over-scoped classic tokens, confirm its
+identity, and run a controlled write canary. The canary pushes a unique
+`automation/homebrew-token-canary-*` branch with a `[skip ci]` commit, creates a
+draft PR, closes it, and deletes the branch with the same token. This proves both
+Contents and Pull requests write access before publication without merging
+anything. The gate also rejects reuse of `RELEASE_GOVERNANCE_TOKEN`.
 No maintainer environment variable is required when creating a tag. Using the
 built-in `GITHUB_TOKEN` is insufficient because organization policy prevents
 Actions from creating pull requests, and its generated PR events may require
 separate workflow approval.
 
+## Release Governance and Recovery
+
+Store `RELEASE_GOVERNANCE_TOKEN` as a dedicated Actions secret with only
+repository `Administration: read`. The immutable-releases REST endpoint is an
+administration setting and cannot be read by the workflow's built-in
+`GITHUB_TOKEN`. Both the default-branch governance preflight and the tag
+contract use this same credential so a missing or expired identity is detected
+before an irreversible tag is created.
+
+Create a protected `release-recovery` environment limited to protected
+branches, with a required reviewer, self-review disabled, and administrator
+bypass disabled. The workflow reads the environment through the GitHub API and
+fails closed unless the required-reviewer, prevent-self-review, and protected-
+branch rules are present.
+Recovery is restricted to an existing annotated tag whose exact tag object,
+commit, and failed tag-push run all match; it then reuses the normal release
+jobs. Do not put publication secrets in temporary branches or create ad-hoc
+recovery workflows.
+
+If the immutable GitHub Release and npm package were delivered but a downstream
+China mirror failed, dispatch the normal `Release` workflow from the protected
+default branch with exactly one of `repair_gitee_version` or
+`repair_oss_version`. Channel repair accepts a failed exact-tag run only when
+its latest attempt completed the release contract, build, Apple signature,
+immutable GitHub publication, and npm delivery checks for the exact tagged
+commit. It then downloads and re-verifies the immutable assets before invoking
+only the selected mirror. An OSS repair requires the OSS step itself to be the
+recorded failure. A Gitee repair accepts either a failed Gitee job or a Gitee
+job that was skipped behind that OSS failure; the latter is an explicit Gitee
+backfill and does not claim that OSS has been repaired. Gitee repair requires
+`GITEE_TOKEN`, `GITEE_USER`, and `GITEE_REPO`; OSS repair requires
+`OSS_ACCESS_KEY_ID`, `OSS_ACCESS_KEY_SECRET`, `OSS_ENDPOINT`, and `OSS_BUCKET`
+(with optional `OSS_PREFIX`) as Actions secrets. Missing credentials fail the
+selected repair closed.

-# Pull request quality gates
+# CI — PR 合入门禁
 
-The repository defines five focused checks in addition to its existing CI:
+The pull-request admission layer has exactly nine required external contexts:
 
-- **Interface Integrity** enforces backwards compatibility. Every historical
-  command path and alias must still resolve, every historical command must
-  still render `-h`, and historical flags must keep their type and shorthand.
-  New commands, aliases, and flags are allowed. The same job compares the full
-  complete `dws schema --all` contract with the PR merge-base, blocking removed
-  products/tools/parameters, incompatible parameter or interface mappings,
-  constraint drift, and safety-semantic drift. It also checks that executable
-  `dws ...` references in `skills/**/*.md` resolve to real commands.
-  Help compatibility covers command/alias/flag spelling, flag type and
-  shorthand; descriptive prose may evolve without breaking the gate.
-- **Coverage** runs unit tests on every pull request and prints both overall and
-  changed-code statement coverage. During the migration to the 80% repository
-  target, overall coverage may not regress from a profile generated from the
-  merge-base with the same test command, while changed production Go
-  statements must meet 80%. Linux, Windows, and macOS each generate a native
-  coverage profile for changed packages and enforce the threshold against
-  changed files buildable on that platform, so build-tagged source cannot be
-  hidden by an Ubuntu-only profile. Overall non-regression allows 0.1 percentage point of measurement
-  variance to avoid failing unchanged code on test-path noise. Set
-  `COVERAGE_ENFORCE_OVERALL=true` once repository coverage reaches 80% to make
-  the overall target fail closed as well.
-- **CLI Smoke** builds the release binary and renders offline help for the root
-  and every public top-level command.
-- **Mock MCP Smoke** runs the existing HTTP and stdio MCP lifecycle tests
-  (`Initialize -> ListTools -> CallTool`).
-- **AI Behavior Check** applies to pull requests labeled `ai-generated`. It
-  limits the change to 30 files and blocks release/CI infrastructure changes.
-  It uses `pull_request_target` without checking out PR code, so the policy
-  cannot be bypassed by changing the workflow in the same pull request. The
-  evaluator writes an `AI Behavior Check` commit status to the PR head SHA so
-  GitHub rulesets can require it.
+| Required context | Contract |
+|---|---|
+| `Lint` | Stable PR revision classification, formatting, `go vet`, and Actionlint |
+| `Test` | Race/unit/release-script tests plus fast cross-platform compilation |
+| `Coverage` | Overall non-regression and 100% changed-code coverage |
+| `Policy` | Repository policy and the fail-closed CHANGELOG contract |
+| `Edition` | Edition contract tests |
+| `Interface Integrity` | CLI, Schema, Skill, and stable-release compatibility |
+| `AI Behavior` | Base-owned policy for PRs labeled `ai-generated` |
+| `CLI Smoke` | Offline help for every public top-level command |
+| `Mock MCP` | HTTP and stdio MCP lifecycle smoke tests |
 
-## Running the compatibility gates
+The workflow display name is `CI`. Parallel helper
+jobs may implement `Test` and `Coverage`, but they are not ruleset contexts.
+Do not require an aggregate alias or a downstream integration check in place of
+the nine contracts above.
 
-Run:
+`AI Behavior` is evaluated by a `pull_request_target` workflow that never
+checks out or executes PR code. It writes the exact `AI Behavior` status to the
+current PR head. Its Files API read is bracketed by base/head revision checks,
+so a synchronize race fails closed. The same workflow supplies a successful
+`AI Behavior` check run on protected `main` pushes for release governance.
+
+## Exact CHANGELOG-only fast path
+
+A pull request qualifies only when GitHub reports exactly one changed file,
+that file is an in-place modification of `CHANGELOG.md`, and the base and head
+both retain it as a regular non-executable `100644` blob. Add, delete, rename,
+symlink, executable-mode, and second-file changes do not qualify.
+
+`Lint` classifies the Files API result only after verifying that the API's base
+and head equal the event revision both before and after pagination. `Policy`
+checks out GitHub's PR merge ref and verifies its parents:
+
+```text
+HEAD^1 = pull_request.base.sha
+HEAD^2 = pull_request.head.sha
+```
+
+It then runs:
+
+```sh
+./scripts/policy/check-changelog-pr.sh \
+  --fast-path "$PR_BASE_SHA" HEAD
+```
+
+Because the verified PR diff contains only `CHANGELOG.md`, the validator and
+its policy dependencies in that merge tree are byte-for-byte the current base
+versions. Validation targets the synthetic merge tree, not the feature-branch
+tree, so a stale branch cannot supply an older validator or combine with newer
+base notes into an invalid final CHANGELOG.
+
+All nine admission contexts are still emitted and must succeed. Expensive
+implementation helpers are skipped; the named contexts record that their code
+surface is unaffected. After merge, the protected `main` push executes the
+full admission suite.
+
+Any PR that touches `CHANGELOG.md` but also changes another file runs the same
+content contract in `Policy` with `--content-only`. That mode permits the
+second file but still rejects invalid dates or versions, missing bullets,
+placeholder `TODO`/`TBD`, unmanaged-section changes, and unsafe tree modes.
+Adding a second file therefore cannot bypass CHANGELOG validation.
+
+## Platform and downstream boundaries
+
+Ordinary PRs run the primary Linux assurance plus fast Darwin/Windows compile
+checks. Full native macOS/Windows tests and platform coverage run on a PR only
+when its diff touches auth, keychain, OS-specific Go files, installers,
+packaging, Formulae, or release automation. Protected `main` pushes run the
+complete native matrix.
+
+Complete `Multi-profile E2E` is not a PR admission context. It belongs to the
+`Main Integration — 主干集成` workflow and runs only after a push to `main` (or
+an explicit manual dispatch). A failing downstream run remains a real
+regression and must be repaired, but it must not be represented by a synthetic
+successful PR check.

+## Running focused gates locally
+
+Run the contracts relevant to the change:
 
 ```sh
 make build
+make policy
 make interface-integrity
 make authoritative-interface-integrity BASE_REF=<merge-base>
 make schema-compatibility BASE_REF=<merge-base>
 make skill-command-integrity
 make cli-smoke
-make coverage-gate BASE_REF=<merge-base>
-# Run on the corresponding native runner with its generated profile:
-make coverage-gate-platform BASE_REF=<merge-base> PROFILE=<coverage-profile>
+make mock-mcp-smoke
+go test -v -count=1 ./pkg/editiontest/...
 ```
 
-CI derives the authoritative Interface snapshots from both the PR merge-base
-and the latest reachable stable release tag. The complete Schema snapshot comes
-from the PR merge-base, which contains the registry-first Schema introduced on
-`main`. The candidate branch cannot bless a breaking change by editing a
-fixture. Schema additions are allowed; historical products, tools, parameters,
-parameter mappings, positional execution fields, constraints, and safety
-semantics remain protected. Positional descriptions are documentation and may
-change without breaking compatibility.
+For an exact CHANGELOG-only branch:
 
-`make update-interface-baseline` still extends the local checked-in Interface
-fixture used by `make interface-integrity`. Updates are monotonic: they add new
-commands and flags without removing history.
+```sh
+base_ref=$(git merge-base HEAD origin/main)
+./scripts/policy/check-changelog-pr.sh --fast-path "$base_ref" HEAD
+```
 
-For an intentional compatibility reset at a major-version boundary, run
-`make reset-interface-baseline`. This replaces all CLI compatibility history
-with the current command tree and must receive explicit human review.
+`make coverage-gate` is an enforcement step, not a profile generator. CI
+generates the candidate, supporting, merge-base, and (when risk-selected)
+native profiles before the aggregate `Coverage` context evaluates them. The
+aggregate and native gates require 100% coverage for changed executable Go
+statements. Overall coverage remains an unrounded, zero-tolerance merge-base
+non-regression check. Candidate and baseline profiles are evaluated by the
+same block-deduplicating checker; supporting policy and shortcut profiles
+contribute to changed-code coverage only. The checked-in badge is presentation
+only and is never read as a gate input.
+
+Compatibility checks derive authoritative Interface snapshots from the PR
+merge-base and the latest reachable stable release. The candidate cannot bless
+a breaking change by editing a fixture. Schema additions are allowed;
+historical products, tools, parameters, mappings, positional execution fields,
+constraints, and safety semantics remain protected.
 
 ## Required GitHub repository settings
 
-Create a ruleset for `main` that requires pull requests and code-owner review,
-then mark these aggregate status checks as required:
+The `main` quality ruleset must enable strict required-status-check policy
+(`strict_required_status_checks_policy=true`) so a PR is revalidated whenever
+`main` advances. It must require these exact contexts and no legacy aliases:
 
-- `CI Gate`
-- `Multi Profile E2E`
-- `AI Behavior Check`
+- `Lint`
+- `Test`
+- `Coverage`
+- `Policy`
+- `Edition`
+- `Interface Integrity`
+- `AI Behavior`
+- `CLI Smoke`
+- `Mock MCP`
 
-`CI Gate` fails closed unless every first-layer CI job succeeds, including
-lint, tests, native Linux/Windows/macOS coverage, policy,
-Interface/Schema/Skill integrity, and smoke tests. Requiring the aggregate
-check keeps repository rules stable when an internal job is renamed or split.
-
-The `ai-generated` label must be applied by the PR-creation automation or by a
-maintainer; GitHub cannot infer reliably whether a human-authored PR contains
-AI-generated code.
+Do not require helper jobs, `Multi-profile E2E`, or an aggregate admission
+alias. Update ruleset contexts only after the new names have appeared on the
+protected branch, so a rename cannot silently remove enforcement or leave an
+unproducible required context.

+# 发布手册（预发 / 正式）
+
+发布只走一条链路：本地脚本负责封板、验证并推送 annotated tag；GitHub Actions 负责构建和发布最终产物。不要直接运行 `goreleaser release`，也不要手工补打或移动 tag。
+
+发布前必须完成平台治理：目标 GitHub 仓库已启用 immutable releases，`main` 精确要求 `CI` workflow 的九个 context：`Lint`、`Test`、`Coverage`、`Policy`、`Edition`、`Interface Integrity`、`AI Behavior`、`CLI Smoke`、`Mock MCP`，操作机已安装并登录 `gh`。本地脚本会在封 tag 前通过 API 检查 immutable releases、当前 SHA 的全部九个 context 和在途 Release；`v*` tag ruleset 仍需仓库管理员预先配置并由操作人确认。
+
+## 日常只用一个入口
+
+安装发布 Skill 后直接运行：
+
+```bash
+dws-release
+```
+
+零参数会进入引导模式。仓库内的等价入口是 `./scripts/release/dws-release.sh`。第一次使用只需配置一次生产发布远端，命令会把远端名及其规范化仓库身份一起保存在当前 Git 仓库中：
+
+```bash
+dws-release config --remote origin
+```
+
+之后命令按仓库状态自动走到正确步骤：缺少精确 CHANGELOG 章节时只生成模板并停止；补全、提交并合入 `main` 后，再运行同一条命令就会安全快进本地 `main` 并执行完整预检。若同名 remote 后续被改指向其他仓库会直接拒绝。只有显式增加 `--publish` 才会进入 tag 发布，且底层仍要求最终版本确认。
+
+## 发布模型
+
+```text
+main 上的候选代码 + beta CHANGELOG
+  → vX.Y.Z-beta.N（预发验证）
+  → 只允许补正式 CHANGELOG，源码不得再变化
+  → vX.Y.Z（正式发布）
+```
+
+正式版必须显式指定本次验证过的 beta。脚本会比较两者：除 `CHANGELOG.md` 外只要有任何文件变化，就拒绝正式发布。这样预发测过的代码、命令树和正式发布的代码是同一份。
+
+## 预发发布
+
+运行统一入口：
+
+```bash
+dws-release v1.2.3-beta.1
+```
+
+如果 CHANGELOG 尚不存在，该命令只生成模板并停止。补全内容、删除所有 `TODO`，提交后通过 PR 合入 `main`；然后重新运行完全相同的命令，它会执行完整预检：
+
+```bash
+dws-release v1.2.3-beta.1
+```
+
+预检包含测试、策略检查、旧正式版命令树兼容检查、全平台打包、npm 安装验证，以及 macOS 环境下的 Homebrew 安装验证。它还会从默认分支触发一次无发布权限的 `Release governance preflight`，用正式流水线相同的身份检查该精确 commit 的九个 Code Admission context 和 immutable releases。通过后会在当前 Git worktree 的私有 Git 状态目录写入一个有效期六小时的证明，绑定版本、精确 commit、发布仓库、beta/stable 基线和远端 `main`：
+
+```bash
+dws-release v1.2.3-beta.1 --publish
+```
+
+若源码、版本、远端身份和 stable 基线均未变化，`--publish` 会复用该证明，只执行远端契约、发布身份和最终治理复核，不再重复测试与打包。也可以直接运行 `--publish`；没有可复用证明时只会完整执行一次预检。命令在封 tag 前仍要求再次输入完整版本号，统一入口不提供跳过确认的参数。
+
+## 正式发布
+
+beta 验证通过后，运行正式版入口：
+
+```bash
+dws-release v1.2.3 --from-beta v1.2.3-beta.1
+```
+
+首次运行只生成正式版 CHANGELOG 并停止。补全内容、删除 `TODO`，提交后通过 PR 合入 `main`；重新运行同一条命令做完整预检，确认后增加 `--publish`：

+```bash
+dws-release v1.2.3 --from-beta v1.2.3-beta.1
+dws-release v1.2.3 --from-beta v1.2.3-beta.1 --publish
+```
+
+`FROM_BETA` 不会自动推断，并会写入 stable annotated tag 的 `From-Beta` 元数据，CI 会再次读取和验证。
+
+## CHANGELOG 契约
+
+每个 tag 必须有唯一、非空且不含 `TODO/TBD` 的精确章节：
+
+```markdown
+## [1.2.3-beta.1] - 2026-07-11
+
+### Changed
+
+- 本次 beta 验证的用户可见变化。
+```
+
+正式版使用 `## [1.2.3] - YYYY-MM-DD`。该章节会直接成为 GitHub Release Notes。
+
+## CI/CD 保证
+
+- 只接受 `vX.Y.Z-beta.N` 和 `vX.Y.Z`，且新版本必须高于上一正式版。这里的“上一正式版”必须同时具备公开非草稿 GitHub Release 和同 tag/commit 的成功 Release workflow；只有 tag、没有交付成功的孤儿版本会阻断后续发布，要求先重跑补齐。历史版本若曾通过专用 recovery workflow 完成交付，只能使用仓库内 `delivered-stable-recoveries.json` 中精确到 tag、commit、run、workflow SHA 与 attempt 的 reviewed 证据；验证仍要求 release、Darwin 签名和最终发布三个 job 全部成功，不能接受任意 workflow_dispatch。
+- tag 必须是 annotated tag；本地脚本在推送前重新确认 HEAD 与远端 `main` 完全一致，CI 允许其后 `main` 前进，但要求封板提交仍位于 `main` 历史中。
+- 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。
+- stable 发布到 npm `latest`，更新 OSS `latest.txt` 和共享安装脚本；prerelease 发布到 npm `beta`，只更新 OSS `beta.txt`，不会覆盖稳定入口。
+- Release workflow 使用一个最多容纳 100 个 pending run 的串行 publication queue；本地入口仍要求上一条 Release 完成后才能封下一个 tag。
+- 本地 tag push 失败时会删除本次新建的本地 tag。tag 一旦成功推送，后续发布归 CI 所有，禁止改 tag 指向或复用版本号。
+
+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。
+
+OSS/Gitee 分发失败且 GitHub immutable Release、npm 已交付时，从受保护的默认分支触发
+Release workflow，并且只填写 `repair_oss_version` 或 `repair_gitee_version` 之一。channel
+repair 会精确绑定失败 tag run 的最新 attempt；contract、构建、Developer ID 签名、
+immutable GitHub 发布和 npm delivery 必须全部成功，且只能有一个 OSS/Gitee 下游失败，
+随后才会下载并重新校验原始资产、修复所选镜像。OSS repair 必须匹配失败的 OSS step；
+Gitee repair 还允许其 job 因该 OSS 失败而 skipped，此时只代表 Gitee backfill 成功，
+不会把仍未修复的 OSS 标成成功。该证据不能用于 beta → stable 或
+stable baseline，后两者仍要求整条 Release 成功或受保护 recovery 成功。不要重跑旧
+attempt 的单个 failed job，以免在 attempts 之间拼接交付证据。独立 Gitee release
+workflow 和本地直发脚本已停用，避免绕开 publication queue 或用重新构建的不同字节覆盖镜像。
+
+## 既有 tag 的紧急恢复
+
+tag push 已成功、但 Release workflow 失败且 GitHub Release 尚未公开时，不要新建临时 workflow、移动 tag 或跳过门禁。在最新且干净的 `main` worktree 运行：
+
+```bash
+dws-release recover v1.2.3-beta.1
+```
+
+命令会自动解析 annotated tag object、peeled commit 和最近一次匹配的失败 tag-push run；也可以用 `--failed-run <run-id>` 精确指定。确认完整版本号后，它从默认分支触发受保护的恢复模式并等待完成。恢复模式必须满足：
+
+- 输入精确绑定原 annotated tag object、commit 和失败的 exact-tag `Release` run；commit 必须仍在 `main` 历史中。
+- 目标只允许不存在 GitHub Release 或仍为 Draft；已经公开的版本只能走对应的 channel repair，不能全量重建。
+- `release-recovery` environment 必须限制为受保护分支、配置至少一名 required reviewer，并禁止自审；workflow 会通过 API 复核这些设置，未配置时 fail closed。
+- 恢复复用正常的 contract、构建、Developer ID 签名、资产校验、immutable 发布、Homebrew、npm 和 OSS jobs，不存在 recovery 专用 publisher 或门禁跳过。
+- 如果 GitHub Release 已在 recovery 中封存、后续 Homebrew/npm 校验发生瞬时失败，只重跑该 run 的 failed jobs；流水线仅在隐藏 run marker、tag object、commit 和 finalized artifact 字节全部精确一致时复用公开 Release。
+
+成功的默认分支恢复 run 会成为后续 beta → stable 和 stable baseline 验证的可审计交付证据；历史临时分支恢复仍只接受 reviewed manifest 中的固定证据。
+
+OSS 的 `latest.txt` / `beta.txt` 当前是镜像频道元数据；仓库内安装器仍从 GitHub/Gitee 解析版本，不能把 OSS pointer 当成已接入的安装通道。
+
+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。
+
+## 平台治理前置
+
+仓库管理员还需要在 GitHub 平台配置以下不可由脚本替代的规则：
+
+- `main` 必须精确要求 `Lint`、`Test`、`Coverage`、`Policy`、`Edition`、`Interface Integrity`、`AI Behavior`、`CLI Smoke`、`Mock MCP` 九个 Code Admission context；tag workflow 也会通过 Checks API 再确认该封板 SHA 上九项全部成功。
+- 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。
+- 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。
+- 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。
+
+immutable releases，或任一 Code Admission context 缺失、未成功时，发布脚本会自动拒绝封 tag。tag ruleset 可能来自组织层，脚本不自动推断其最终作用范围；管理员确认不能省略，脚本约定也不能替代平台强制。
