chore: prepare GoodBuddy 0.11.14 releases

Set the Desktop package metadata and approved bilingual notes to 0.11.14,
aligned with the coordinated Agent 0.11.14 lock and release-status docs. This
candidate uses the standard x64/arm64 release matrices and does not include an
experimental LoongArch preview.

Release note: 准备 GoodBuddy Desktop 与 Agent 0.11.14 正式发布，包含托管 SSH 任务恢复、有界诊断和桌面反馈改进。

+GoodBuddy is a cross-platform Electron desktop assistant for internal

+SQLite. User-facing copy is primarily Simplified Chinese.
 
 ## Product Priorities
 
+GoodBuddy is primarily an internal-network product. Unless the user states
+otherwise, assume a trusted organizational environment, not a hostile public,
+multi-tenant, or zero-trust deployment.
+
 Use this order when requirements or implementation choices compete:
 
-1. Working product functionality.
-2. Performance and responsiveness.
+1. Complete, working product functionality.
+2. Measured performance and responsiveness.
 3. Clear, low-friction user experience.
 4. Simple, conventional, maintainable implementation.
-5. Security controls proportional to a concrete, realistic risk.
+5. Security controls only for a concrete risk in the actual deployment model.
 
-Follow KISS and YAGNI. Do not add trust tiers, consent ceremonies, durable
-state machines, protocol phases, cryptographic identities, quotas, recovery
-machinery, or compatibility layers unless they are needed for an actual user
-workflow or a demonstrated failure mode. Prefer the normal platform mechanism
-and the smallest design that works. Test Hosts are test environments; do not
-turn their workflows into production compliance exercises.
+Functionality and performance are the primary acceptance criteria. Do not
+disable, delay, restrict, or complicate a working product path for speculative
+security hardening. Preserve the existing Electron, credential, user-data, and
+release-signing boundaries, but do not expand them without a concrete current
+risk or an explicit user requirement.
+
+## Design Simplicity
+
+Follow KISS and YAGNI. Use the smallest conventional design that completes the
+real user workflow.
+
+- A demonstrated failure authorizes only the smallest proportional fix, not a
+  general recovery, compatibility, or security framework.
+- Prefer deleting bounded staging and retrying, idempotent operations, and
+  reconciliation from one authoritative source of truth. Do not persist copies
+  of state that can be derived or safely retried.
+- Do not add durable snapshots, journals, versioned internal receipts, rollback
+  engines, compatibility readers, multi-phase state machines, protocol phases,
+  cryptographic identities, trust tiers, consent ceremonies, or quotas when
+  cleanup, retry, or reconciliation is safe.
+- Before introducing any of that machinery, stop before coding. Explain the
+  reproducible current failure, why the simple alternative is insufficient,
+  and obtain the user's explicit approval for the added complexity. A reviewer
+  suggestion, test-only scenario, hypothetical crash, or possible future need
+  is not sufficient evidence.
+- Performance outranks simplicity only for a measured bottleneck. Security
+  complexity requires a concrete threat at an actual trust boundary.
+- Ignore hypothetical threats that require a hostile public network,
+  untrusted tenants, or zero-trust deployment unless that environment is an
+  explicit product requirement. Do not turn such findings into implementation
+  work.
+- A complete workflow means the normal production path plus demonstrated
+  failure cases. It does not require exhaustive recovery from every
+  hypothetical interruption point.
+- Test Hosts are test environments. Do not turn their workflows into production
+  compliance exercises.

-## Release Packaging
+## Releases
 
-- `.github/workflows/packages.yml` is the canonical cross-platform packaging
-  workflow. It validates and builds `out` once, then packages on six native
-  runners: Windows, macOS, and Linux, each for x64 and arm64.
-- The experimental Linux LoongArch (`loong64`) preview is built separately
-  through `build/loongarch-cross` by following
-  `docs/development/loongarch-preview-build.md`. It is not part of
-  `.github/workflows/packages.yml`, the six-runner GitHub Actions matrix,
-  standard release manifests, GitHub Release asset expectations, or the
-  production update index. Do not add it to those paths unless the user
-  explicitly requests a future production-support migration.
-- Run the unified packager with
-  `npm run release:package -- --platform <platform> --arch <arch>`. It only
-  packages for the native host and writes to
-  `dist/release/<platform>-<arch>`.
-- Default deliverables are NSIS and portable ZIP for Windows, DMG and ZIP for
-  macOS, and AppImage, DEB, and RPM for Linux. Every target includes
-  `release-manifest.json` with SHA-256 hashes.
-- `build/build-release.cjs` verifies the unpacked application, `app.asar`,
-  bundled Continue and OpenCode runtimes, executable architecture, and package
-  signatures before atomically replacing a release directory.
-- All desktop build paths, including local `portable`, package the Agent and
-  remote Runtime version locks plus the public signing-key registry without
-  embedding installable Linux Agent or remote Runtime payloads. Managed SSH is
-  optional: users explicitly download a compatible compound `.gbagent` package
-  from Settings or import one offline before GoodBuddy can install or update a
-  Host.
-- Each independently published Linux x64 or arm64 `.gbagent` contains the
-  Agent daemon, pinned Node, and the desktop-maintained compatible OpenCode
-  Runtime. Build both architectures on native GitHub Actions runners from one
-  immutable `agent-v<agentVersion>` tag.
-- Keep the GoodBuddy Agent source, shared protocol/contracts, runtime lock,
-  bundle tooling, and tests in this repository so a desktop commit identifies
-  the exact Agent source it expects. Do not create a separate Agent repository
-  or long-lived Agent release branch unless the Agent becomes an independently
-  released product serving multiple clients.
-- `.github/workflows/agents.yml` is the branch and pull-request build
-  verification workflow for GoodBuddy Agent. It must build Linux x64 and
-  arm64 on native runners from the checked-out commit, acquire the locked
-  official Node archive and locked OpenCode npm archive, verify every locked
-  digest, use only an ephemeral in-memory test signing identity, and verify the
-  resulting compound package and deterministic archive. It must not read
-  production signing secrets, publish installable release artifacts, or modify
-  the checked-in public key registry.
-- `.github/workflows/agent-release.yml` is the only production compound Agent
-  publication path. It requires an annotated immutable Agent tag, the protected
-  `agent-signing` Environment, native x64/arm64 builds, one production
-  GoodBuddy signing identity for every layer of the compound package and
-  catalog, a non-Latest GitHub Agent Release, and synchronized immutable
-  Beijing OSS objects plus the final signed latest-catalog pointer.
-- `.github/workflows/packages.yml` and `release:package` build only desktop
-  products. Missing Agent packages, remote Runtime inputs, or GoodBuddy signing
-  credentials must never block an ordinary desktop package or release.
-- Keep electron-builder invocations on `--publish never`. Main-branch builds
-  run validation and build the production bundle without running the native
-  package matrix. Manual builds upload 30-day GitHub Actions artifacts.
-  Version-tag builds verify and aggregate packages before publishing GitHub
-  Release assets. The macOS jobs sign, notarize, and verify packages when all
-  five Apple credentials are configured. With no Apple credentials they must
-  use the explicit `--unsigned` path, warn that Gatekeeper may block the
-  packages, and still complete; a partial credential set must fail rather than
-  silently downgrade.
-- Keep `ELECTRON_CACHE` and `ELECTRON_BUILDER_CACHE` under
-  `${{ runner.temp }}` in step-level workflow contexts. A cache beneath the
-  repository inherits the root `"type": "module"` and breaks electron-builder's
-  CommonJS macOS icon tool.
-- Tag builds must use `v${package.version}`. The workflow also supports manual
-  dispatch and main-branch changes to release tooling.
+Detailed release operations are governed by
+[`docs/development/release-runbook.md`](./docs/development/release-runbook.md).
+Read that runbook only when preparing, publishing, recovering, or verifying a
+desktop or GoodBuddy Agent release. It is an operator and CI procedure, not an
+authorization to add product persistence or recovery machinery.
 
-### Agent Release Process
+Repository-wide release invariants:
 
-- Agent releases use annotated `agent-v${agent-runtime-lock.agentVersion}` tags
-  and are separate from desktop `v${package.version}` releases. Confirm the
-  exact Agent release commit and tag with the user before creating or pushing
-  either.
-- The tagged commit must be reachable from protected `main`. The two native
-  jobs build the compound x64/arm64 packages from the same source and locks;
-  the catalog job rejects missing architectures, changed bytes for an existing
-  version/architecture identity, invalid prior signatures, and incompatible
-  matrix metadata.
-- Agent GitHub Releases are ordinary non-draft, non-prerelease releases but
-  must use `--latest=false`; they must never replace the desktop release marked
-  Latest. Publish immutable packages and the versioned catalog to
-  `agent-releases/v<agentVersion>/` in Beijing OSS, publish the GitHub Agent
-  Release, then atomically update the single `agent-releases/latest.json`
-  pointer to that version's immutable catalog and signature.
-- Do not report an Agent release complete until both public package
-  architectures match the signed catalog by size and SHA-256, the GitHub and
-  OSS catalog bytes/signatures are identical, the application can read the
-  selected source, and GitHub's repository Latest tag remains the desktop tag.
-
-### Tagged Release Process
-
-Every version-tag release must follow this sequence. A branch-only push does
-not require release notes.
-
-1. Confirm that the user wants a release tag and identify the exact release
-   commit and the new `package.json` version. Separately ask whether this
-   release should also receive an experimental LoongArch preview build; never
-   infer that choice from an earlier release.
-2. Find the latest stable version tag reachable before the release commit and
-   inspect the complete commit and file diff from that tag to the release
-   commit. For the first tagged release, inspect the relevant repository
-   history instead.
-3. Draft concise, user-facing release notes in both Simplified Chinese and
-   English based only on verified changes in that range. Use the titles
-   `GoodBuddy <version> 更新内容` and
-   `What's New in GoodBuddy <version>`, with corresponding `功能更新` /
-   `Features` and `问题修复` / `Bug Fixes` sections when applicable. The two
-   language versions must describe the same changes. Do not expose
-   internal-only details, credentials, private content, or unverified claims.
-4. Show the exact bilingual release-note draft to the user and wait for
-   explicit approval. If the release commit or either language version changes
-   after approval, inspect the updated tag range and request approval again.
-5. Write the approved notes to the single entry for the release version in
-   `resources/release-notes.json`. A failed unpublished candidate whose content
-   is carried forward must not retain a duplicate packaged entry.
-6. Verify that `package.json`, the root `package-lock.json` version, and
-   `package-lock.json.packages[""].version` all equal the release version. Run
-   `npm run release:notes:verify`, the required source validators, the
-   production build, and any native candidate launch probe available on the
-   current host. The six native CI jobs remain the cross-platform authority.
-   If the user requested a LoongArch preview in step 1, build it separately
-   from this exact candidate by following the LoongArch build document, record
-   its size and SHA-256, and keep it outside the standard GitHub/OSS release
-   asset set unless the user separately authorizes publishing it.
-7. Fetch both remotes immediately before tagging. Inspect any remote branch
-   movement instead of overwriting or silently merging it. Confirm the working
-   tree is clean, the candidate tag is unused locally and remotely, and the
-   exact approved commit has not changed.
-8. Only after all previous steps pass, create an annotated
-   `v${package.version}` tag at the exact approved commit. Push `main` to
-   `origin` and `github`, verify both branch SHAs, then push the tag to both
-   remotes and verify each peeled tag SHA (`refs/tags/<tag>^{}`) equals the
-   release commit.
-9. Keep both approved language versions as the single source for the GitHub
-   Release body and the packaged first-open release-notes modal. The modal
-   displays the release notes matching the current interface language and
-   contains no button linking to a full release page.
-10. Observe the tag workflow through publication and complete the public
-    verification checklist below. A successful push is not a completed
-    release.
-
-### OSS Publication Contract
-
-The tagged release job publishes through the GitHub Environment selected by
-`.github/workflows/packages.yml` (`aliyun-oss-release`) and reads the following
-effective GitHub Actions variables. Before a release or same-tag rerun can
-publish, verify that repository-, organization-, or environment-level
-resolution exposes:
-
-- `ALIYUN_OSS_BUCKET=goodbuddy`
-- `ALIYUN_OSS_ENDPOINT=https://oss-cn-beijing.aliyuncs.com`
-- a non-empty `ALIYUN_OIDC_PROVIDER_ARN` matching
-  `acs:ram::*:oidc-provider/*`
-- a non-empty `ALIYUN_ROLE_ARN` matching `acs:ram::*:role/*`
-
-For environment-scoped values, use the exact Environment name from the
-workflow; do not assume a similarly named UI environment such as `Production`
-contains the active variables.
-
-The Bucket and Endpoint are a deployment contract, not interchangeable
-examples. They must stay aligned with the trusted URL checks in
-`src/main/version-checker.ts`, `sites/app.js`, website validation, and related
-tests. A host, Bucket, Region, or CDN migration must update and validate every
-surface together before a new release.
-
-- Use GitHub OIDC and the RAM Role to obtain short-lived STS credentials.
-  Never add long-lived AccessKeys to repository or environment secrets.
-- Keep `ossutil` pinned. Its V4 signing requires the Region; derive it from the
-  canonical Endpoint, verify that the production value resolves to
-  `cn-beijing`, and pass `--region` to every `ossutil cp`, including the final
-  `latest.json` update.
-- Grant the RAM Role only the actions and prefixes required by the workflow.
-  It must be able to write immutable version objects and the final latest
-  pointer without granting unrelated administration privileges.
-- Upload release assets and `site-release.json` under the immutable
-  `releases/<tag>/` prefix first. Verify all 14 installer URLs publicly before
-  creating or publishing the GitHub Release. Update
-  `releases/latest.json` only after the GitHub Release is public and all prior
-  checks succeeded.
-- The expected GitHub Release contains 22 assets: 14 installers (two formats
-  for each Windows/macOS target and three formats for each Linux target), six
-  renamed target manifests, one aggregate `release-manifest.json`, and one `SHA256SUMS`.
-  `site-release.json` is an OSS publication artifact, not a GitHub Release
-  asset.
-
-### Failed Tag Recovery
-
-Classify a failed tag by the external side effects that completed before
-choosing a recovery:
-
-- If no source or release metadata must change, correct only the external
-  configuration and use **Re-run failed jobs** for the same immutable tag. Do
-  not change, move, delete, or recreate the tag.
-- If immutable OSS objects were partially uploaded but their source bytes are
-  unchanged, a same-tag rerun may idempotently re-upload or verify them. Never
-  point `latest.json` at a partially verified prefix.
-- If the GitHub Release is already public but the final latest-pointer step
-  failed, it is a published version. Keep its packaged notes and rerun the
-  failed release job for the same tag; do not classify it as an unpublished
-  candidate.
-- If code or release metadata must change, keep the failed tag immutable,
-  increment the patch version, obtain approval for the revised exact release
-  commit and notes, and create a new tag. Do not reuse the failed version.
-
-When recovering from a version tag whose workflow never published a public
-GitHub Release:
-
-- If a code or metadata change requires a higher version and a new tag, carry
-  the failed candidate's approved user-facing notes forward into the recovery
-  version, then remove the superseded failed version's entry from
-  `resources/release-notes.json`.
-- The packaged first-open modal must show that carried-forward content only
-  once under the recovery version. Never retain both the failed version and
-  its cumulative recovery copy, because users upgrading across them would see
-  duplicate content.
-- Never remove the packaged history for a version that successfully published
-  a GitHub Release. Verify the failed release state before treating an entry as
-  superseded.
-
-### Post-Publication Verification
-
-Do not report a release complete until all of the following are verified:
-
-1. The tag workflow and all six native package jobs succeeded. Verify the
-   recorded macOS signing mode: signed builds must pass `codesign`, `spctl`,
-   and `stapler`; unsigned builds must record the Gatekeeper caveat in the
-   Actions log and job summary. In the final release job, explicitly verify
-   the OSS configuration, OIDC authentication, release-index generation,
-   immutable upload, public asset check, GitHub Release publication, and
-   latest-pointer steps.
-2. The public GitHub Release is non-draft, non-prerelease, marked Latest, and
-   uses the expected tag and title. Its body must exactly match the Markdown
-   generated from the approved packaged bilingual notes.
-3. The GitHub asset set has exactly the expected 22 names and every asset is
-   uploaded. Compare installer sizes and SHA-256 digests with the aggregate
-   manifest and `SHA256SUMS`.
-4. The Beijing `releases/latest.json` returns HTTP 200, has the expected stable
-   version, exact six targets and 14 installer entries, the trusted Beijing
-   URLs, and the GitHub fallback URL. It must match the immutable
-   `releases/<tag>/site-release.json`.
-5. All 14 public installer URLs accept `HEAD` without redirects and report the
-   declared size. For small JSON/checksum metadata, prefer a `GET` byte and
-   digest comparison; OSS may gzip JSON responses and omit an uncompressed
-   `Content-Length` on `HEAD`.
-6. The live website successfully fetches the index and produces the 14 correct
-   platform/architecture/format links. Exercise the application's actual
-   mirror checker against the public index for all six targets.
-7. Both remote `main` refs and both peeled tag refs still equal the approved
-   release commit, and the local working tree is clean.
-
-Never create or push a release tag, and never push a previously created
-release tag, before the release-note draft has received explicit approval.
-
-- Before a push that updates the `github` remote, ask whether the user wants a
-  release tag unless they already specified that choice. A branch-only push
-  does not require a version bump or tag. When the user requests a release,
-  verify that `package.json` and `package-lock.json` contain the same release
-  version, create `v${package.version}` at the exact commit being pushed, and
-  push that tag so the native package matrix and GitHub Release run.
-- Never move or reuse an existing release tag. If `v${package.version}` already
-  exists locally or on a remote at another commit, increment the package
-  version and create a new matching tag before the release push.
-- Verified release baseline on 2026-08-18: commit
-  `60119a4317118fa3f077db0382664f15266a6682`, annotated tag `v0.10.4`, and
-  GitHub Actions run `32038633609` attempt 2 succeeded through all six native
-  packages, GitHub Release publication, Beijing OSS publication, and the final
-  `latest.json` switch.
+- Never create or push a release tag before the user approves the exact release
+  commit and bilingual release notes.
+- Never move, delete, recreate, or reuse a release tag.
+- Keep desktop and Agent release paths, tags, artifacts, and Latest status
+  separate.
+- Native GitHub Actions jobs are the cross-platform packaging authority. Never

+### GoodBuddy Agent development validation
+
+Every source change that can alter the deployed GoodBuddy Agent or the
+desktop-to-Agent production path must be validated on the shared Linux x64 test
+Host while the change is being developed. This includes Agent daemon and
+protocol changes, packaging and installation, attach/update behavior, Runtime
+launch and process ownership, workspaces, model bridges, and lifecycle or
+recovery behavior. Unit tests, mocks, fixtures, CI, and waiting for release
+validation are not substitutes for this development-time check.
+
+- Reach the shared Host at `192.168.0.23` on the LAN when available, otherwise
+  use `10.7.0.23` over VPN. These are two routes to the same physical machine,
+  not two independent test targets or architecture results.
+- Exercise the current source or package under development, not only the
+  previously published Agent. Run the affected production path as soon as it is
+  runnable and repeat the relevant scenario after the final change.
+- Select the real-Host scenario from the changed surface: attach/bootstrap or
+  update for installation changes; Ask/Execute and a bounded real model request
+  for Runtime or model-bridge changes; and the applicable disconnect, restart,
+  cancellation, or reconnection sequence for lifecycle and recovery changes.
+- Use the existing pinned Host identity and GoodBuddy credential storage. Never
+  add credentials to source, documentation, commands, logs, or test output, and
+  never hard-code these test addresses into product behavior or defaults.
+- Keep all artifacts in GoodBuddy-owned test directories. Before stopping or
+  changing a remote process, verify that it belongs to the test run; never
+  modify unrelated Host files or processes.
+- If neither route is reachable, report the real-Host validation as blocked and
+  do not present the Agent work as complete or defer its first real validation
+  to release time.
+
+The detailed scenario rules are documented in
+[`docs/architecture/remote-host-and-goodbuddy-agent-design.md`](./docs/architecture/remote-host-and-goodbuddy-agent-design.md).
+
 Before committing or pushing, inspect `git status`, `git diff`, and
 `git diff --cached`. Do not commit secrets, local databases, logs, generated
 credentials, or private user artifacts.
 
+Before a push that updates the `github` remote, ask whether the user wants a

 - [x] **OpenCode Runtime 定制**：GoodBuddy 管理的内置 OpenCode 可发现原生 Agents、Tools、Commands、LSP、Formatters、MCP、Skills、Prompts 与 Resources；Tools 单独显示读取、文件修改、命令、网络、Agent 编排等类型、来源及 Ask/Execute 可用性，并隐藏 OpenCode 内部 `invalid` 与 GoodBuddy 临时 MCP 工具。支持保存默认 Agent、每次请求覆盖 Agent、通过原生 SDK 执行 Command、显示上下文用量并调用有总时限的原生 Compact；并发外部 Server 对话的提问使用请求级公开 ID 映射，回答不会串到其他会话。外部 OpenCode Server 只报告连接状态，不宣称原生清单可读。任意插件安装、Session Share、自动 Worktree 和 OpenCode 原生会话持久化仍不开放。
 - [x] **Continue Runtime 定制**：提供静态配置中的原生 Rules、Prompt 模板与 MCP 清单，以及可编辑的 GoodBuddy Rules/Prompt 配置预设；聊天可按请求选择预设和填入可继续编辑的 Prompt。当前 Continue Host 没有可信的静态原生 Tool 发现接口，且使用隔离的 `CONTINUE_GLOBAL_DIR`，因此界面明确标记 Tools 不支持静态发现，也不把 Host 实际不会加载的工作区或用户 Skills 冒充原生能力；GoodBuddy 分配的 Skills 仍按请求暂存执行。Continue 临时 Host 不复用原生会话压缩，手动压缩由 GoodBuddy 摘要模型完成并验证持久化摘要覆盖范围；Agent 交互提问转换为统一问答卡片。Resources、Hooks、后台 Job 和 Continue 原生会话管理继续暂缓。

 - OpenCode、Continue 和 DeepSeek Harness 后续的 Task 级委派与取消、后台执行进度/结果、Workflow/Hook 运行、长任务暂停/恢复/终止及原生会话监督统一进入应用级助手工作栏固定的“Runtime”栏目，不加入 Composer。栏目入口始终存在；只选择 Conversation 或 Task，并按 Task 聚合执行状态，不显示 Job/Run 树或独立操作菜单。内部可选区域按用户所选目标和 Runtime 的真实能力显示，不为未支持能力渲染空卡片或成排禁用按钮。切换跟随目标时必须清理上一归属的监督状态，固定目标则保持不变。
 - 设置中心只管理持久 Runtime 配置、默认值和能力清单；右侧 Runtime 栏目管理用户当前跟随或固定目标的生命周期。两处不得复制同一实时操作，栏目中的高风险操作仍须就地确认并保留取消、权限、用量和活动审计。
 - Runtime Prompt 快捷操作只把模板填入输入草稿，用户可以继续编辑；OpenCode Command 由 Runtime 原生 API 执行，输入框只承载可选参数，不以普通斜杠文本冒充执行。
+- OpenCode 原生 Task 调用在本地项目和托管 SSH 项目中统一解析为子 Agent 状态卡，不显示为普通工具卡。状态卡持续显示 Agent 类型、任务说明、运行状态、完成输出或失败原因；身份徽标、Agent 名称和状态位于首层，任务说明作为主信息，Runtime 来源作为次级元数据，输出与错误在同一卡片内按需展开。父 Agent 的推理不冒充子 Agent 过程，必须与状态卡保持明确间距。状态不能只靠颜色表达。推理、子 Agent、工具和正文统一按事件首次出现顺序进入消息块；增量更新只更新原位置，Task 临时工具块重分类后必须原位替换，不能把子 Agent 卡统一提升到消息顶部。同一调用的增量事件按稳定调用 ID 更新，不能因 ACP 首帧尚无参数而永久保留重复工具卡或活动记录。一次请求内已观察到的子 Agent 均保留在消息与活动记录中；父请求取消、失败或意外中断时仍处于活动状态的卡片必须结算为对应终态，父请求成功结束但子 Agent 未报告终态时必须显示为失败而不是推断为完成。
 - Agent 回复进行中锁定模型、专家角色、工作模式和 Runtime 定制选择器，并关闭已打开的上下文菜单；回复结束或停止后再恢复选择，避免界面状态与本次运行实际使用的上下文不一致。
 - Agent 回复进行中不能禁用普通消息发送。新消息与到期 Scheduled Task 共用 Conversation 级待发送队列。队列位于 Composer 容器之外、与输入框等宽并保持独立间距；有待发送项时直接显示无标题栏的极简列表，空队列不保留占位。每项固定为一行，按进入顺序显示轻量来源图标和截断摘要；普通消息使用消息图标，Scheduled Task 统一使用淡出时钟图标。
 - 待发送项默认在当前回复结束后顺序执行。每项提供明确的“立即中断并插入”（空闲时为“立即运行”）和删除操作；前者先取消当前 Conversation 的活动执行，再将所选项提升为下一项，不允许同一 Conversation 并发写入时间线。

 - “笔记 / 待办”属于同一工作台内的同级内容面板，使用 `PageTabs` 的 `segmented` 视觉变体，与模型设置的分段控件保持同一外观。
 - 页签切换保留 `tablist`、`tab` 和 `tabpanel` 语义；待办状态仍使用独立的 `SegmentedControl`，不得与内容页签合并。
+- 笔记编辑器保留 Quill 原生列表快捷输入：输入 `-`、`*`、`1.`、`[ ]` 或 `[x]` 后按空格，分别转换为项目符号、编号或待办清单。快捷输入只生成现有 Delta 富文本，不引入 Markdown 源码模式、第二套持久化格式或第三方 Markdown 插件；编辑区附近持续提供简短提示。
+- 左侧笔记列表依次显示标题、最多两行内容预览，以及同一行的记录数和本地化更新时间。记录数靠左、更新时间靠右，窄宽度下均保持单行省略，不挤压标题或扩大列表栏。
 - 左侧“魔法笔记”入口可显示未完成待办数量。数量为 0 时隐藏徽标，超过 99 时显示 `99+`，可访问名称仍说明精确数量；勾选、取消勾选以及 Agent / MCP 对笔记清单的写入都必须刷新数量。
+- 未完成待办徽标的高度不得超过主导航图标；数量从 0 变为可见或再次隐藏时，主导航项行高和相邻菜单位置必须保持不变。
 - 在待办面板勾选或取消勾选后，当前缓存中的源笔记正文必须立即同步对应清单状态，不得依赖离开工作区后重新加载。

 ## Agent 安装与生命周期
 
 - Agent bundle 通过 manifest、Ed25519 签名、payload digest、平台和架构校验。
 - 安装使用当前 SSH 用户目录中的 GoodBuddy-owned 路径和 side-by-side digest 目录。
-- Agent 代码与固定 Node Runtime 是独立 payload。升级时如果当前 Host Agent 的签名
-  manifest、registry identity、owner/mode/size 和 Node digest 都可验证，且候选
-  manifest 声明完全相同的 Node，安装器直接在新的 side-by-side 目录中复用该 Node；
-  否则正常上传候选 Node。Agent 不匹配不会阻止升级，也不会覆盖旧安装。
-- 桌面包只携带版本 lock 与 production 公钥，不携带远端 payload。用户必须先在设置中显式下载最新兼容的目标架构复合包，或导入离线 `.gbagent`；项目激活不会联网下载。每个复合包绑定 Agent、固定 Node 与桌面维护的 OpenCode Runtime 精确工件。应用重启固定进入第一个普通本地项目，不自动连接上次远程项目；用户主动切换托管 SSH 项目时，Main 从本地验证缓存选择 Host 架构工件，Host 尚未安装该 identity 时上传并启动。相同 Renderer 对同一项目的并发激活共享一个 Main 操作。
-- Agent、Workspace 和 Runtime 全部验证成功后，Main 才在同一 SQLite 事务中刷新项目保存的 Agent/Runtime evidence，然后把项目设为当前项目。上传、启动、验证或事务失败时，项目继续绑定旧 identity，不能用未提交的新 identity 绕过持久化绑定校验。
+- Agent 代码与固定 Node Runtime 一起位于签名 compound payload。显式安装或重装从本次
+  已完整校验的准备目录原子发布整个 Agent，不扫描旧安装、不创建跨版本 Node 硬链接；
+  Agent 不匹配不会阻止升级，也不会覆盖 GoodBuddy-owned 路径以外的内容。
+- 桌面包只携带版本 lock 与 production 公钥，不携带远端 payload。Host 卡片只有一个按
+  版本事实显示“安装远程环境”“更新远程环境”或“重新安装”的主按钮；次级

+  它们不取得安装包、不发布组件，也不通过 SFTP 重读或哈希 payload。

+  与其 digest 匹配的有界 manifest 元数据，不在每次项目切换时重新验签或哈希完整 payload。

+  清理旧暂存并重新 prepare/adopt。不要求删除 Host、凭据或引用项目。
+- Host 卡片的“版本匹配”badge 只表达版本事实，不代表 Agent 正在运行或环境健康。重新安装
+  失败时明确显示本次操作未完成，并以随后重新检查的版本卡片表达当前事实；提交结果
+  不确定时不声称旧版本未被替换。
+- 更新成功后才定向清理该 Host 的 Agent 连接和 Runtime 选择缓存。引用项目再次打开时
+  解析新的 current registry 并建立当前连接，无需刷新项目记录；当前环境无效时要求用户
+  显式修复，但不在项目切换中下载或安装。失败或取消保留 Host 配置、凭据、项目、
+  Workspace 和旧组件。
 - 显式 stop、升级、身份冲突或进程退出时清理 GoodBuddy 自己的 socket、状态和子进程；不得删除或覆盖无关 Host 文件。
 
+### Host 级环境生命周期
+
+- Agent、Node 和 Runtime 是 Host/SSH 账号级共享环境。新增或重新验证 Host 后先保存 Host
+  并只读探测，不自动安装；用户随后在 Host 卡片明确选择安装或更新方式，失败保留 Host
+  并允许重试。
+- Host 可以按签名目录固定的 URL、大小和 SHA-256 直接从当前 GitHub/北京镜像来源下载
+  完整 `.gbagent`，也可使用 GoodBuddy 本机下载、流式 SFTP 传输和离线导入。自动模式只在
+  操作开始时择一；执行失败不会在同一次操作中切换 acquisition。
+- 项目只保存 Host ID、远端路径、Runtime 选择和默认模式。创建或保存时验证 Host current
+  环境；打开或切换只读取本地配置。Workspace/Runtime 实际使用时从 Host current registry
+  和当前 Agent 连接取得 live identity，不再扫描、下载、上传或发布 Agent/Runtime。完整
+  事务、兼容边界和验收要求以
+  [Host 环境准备设计](./remote-host-environment-provisioning-design.md) 为准。
+- 打开新建/项目设置弹窗只读取本地 Host 验证记录，不并发检查所有 Host；目录浏览或保存
+  才连接所选 Host。
+- 项目选择器中的管理操作默认浮动隐藏，在悬停、键盘焦点或触屏环境显示。管理任意已保存
+  项目不先激活项目，因此 Host 不可达或远端目录已不存在时仍可删除其本地记录。
+- “远程项目”在选择器中按已保存 SSH Host 轻量分组。Host 标题显示 Main 已持有的真实
+  Agent 连接状态（未连接、连接中、就绪或异常），读取和展示状态本身不连接 Host；
+  项目副标题只显示远端路径，不重复“托管 SSH”类型。
+- 删除 Host 时确认框列出所有引用它的本地项目记录，包括归档项目。确认后只删除本机
+  Host、凭据、项目及其关联记录，不连接 Host、不删除远端目录或内容；Host 设置写入或

+## Agent 开发期间的真实 Host 验证
+
+任何会改变已部署 GoodBuddy Agent 或桌面到 Agent 生产链路的源码改动，都必须在开发期间
+使用共享 Linux x64 真实测试 Host 验证。适用范围包括 Agent daemon、Agent protocol
+及共享 contract、Agent 组包与安装、attach/update、Runtime 启动与进程归属、Workspace、
+model bridge，以及生命周期和恢复逻辑。单元测试、mock、fixture、CI 或正式发布前回归
+都不能替代这一步；不得等到准备发布时才首次运行受影响的真实链路。
+
+测试 Host 有两个网络入口：
+
+- `192.168.0.23`：局域网入口，在本地网络可达时优先使用；
+- `10.7.0.23`：VPN 入口，局域网入口不可达时使用。
+
+两者指向同一台物理 Host，只代表两条访问路由，不能计为两个独立 Host、两种架构或两份
+覆盖结果。测试只使用已固定的 Host identity 和 GoodBuddy 已有凭据存储；地址不得写入
+产品行为或默认配置，用户名、密码、私钥等凭据不得写入源码、文档、命令、日志或测试输出。
+
+开发时应在改动链路达到可运行状态后尽早执行真实 Host 验证，并在最终相关改动后重复受
+影响的场景。必须使用当前源码构建或当前候选包，不能只验证 Host 上已经发布的旧 Agent。
+按改动范围至少选择以下场景：
+
+1. Agent 组包、安装或升级：验证当前候选的 attach-or-bootstrap、安装/更新、版本切换及
+   随后的连接。
+2. Runtime profile、进程启动/归属或 Ask/Execute 边界：通过桌面生产入口启动真实 Runtime，
+   验证受影响模式；Ask 权限改动必须验证只读边界，Execute 权限改动必须验证所需写入、
+   进程和网络能力。
+3. Agent protocol、RPC、stream、model bridge 或模型消息链路：执行最小有界真实模型调用，
+   禁用非必要工具和附件，并记录实际调用次数；大消息或工具链路改动还应覆盖对应的真实
+   payload/工具场景。
+4. 会话、owner、取消、超时、断线或恢复逻辑：执行与改动直接相关的中断、取消、Agent/
+   Runtime 重启、SSH 断开或重连序列，并确认不会错误重放结果未知的操作。
+5. Workspace 或 Host 文件路径：只在 GoodBuddy 专用测试目录操作，验证真实路径和权限，
+   不得读取、覆盖或删除无关 Host 文件。
+
+停止或修改远端进程前必须先核对其启动身份、PID/进程组和 GoodBuddy 归属。若两个入口均
+不可达，应立即把真实 Host 验证报告为开发阻塞，保持该验证未完成，不能把 Agent 改动表述
+为已完成，也不能把首次真实验证推迟到发布阶段。

+# SSH Host 远程环境准备与直连下载设计
+
+## 状态
+
+本文记录 2026-08-28 确认的目标设计及当前实施状态。源码已经实现 Host 手动准备、
+GoodBuddy 传输、Host 直连下载、control-plane one-shot installer、发布后健康 adoption，
+以及项目路径只验证已安装环境。Host 负责 Agent/Runtime 的安装与更新生命周期，项目流程
+只消费已经准备好的 Host 环境。
+
+当前源码可以直接使用既有 package format v1 `.gbagent`：归档已经包含固定 Agent 和
+Node，installer 由 GoodBuddy 桌面控制面打包并通过固定 SSH prepare channel 单次发送，
+不要求归档包含 `agent/lib/package-installer.cjs`，签名目录也不提供或检查额外的
+bootstrap 能力元数据。公开直连能力仍须完成本文末尾 GitHub/北京镜像、Linux x64/arm64、
+取消和离线 GoodBuddy 传输的真实 Host 验收；本文
+不表示这些验收或新的 Agent 发布已经发生。当前实现细节同时以
+[SSH 远程主机与 GoodBuddy Agent 实现说明](./remote-host-and-goodbuddy-agent-design.md)
+和源码为准。
+
+## 设计结论
+
+将安装和更新从项目切换移到 Host 管理是合理的，原因如下：
+
+- Agent、固定 Node 和 OpenCode Runtime 安装在 SSH 账号 Home 下，由同一 Host/账号上的
+  多个项目共享，不属于某一个 Workspace。
+- 大文件传输发生在项目切换时会阻塞导航，也把 Host 级故障误显示成项目故障。
+- Host Key、认证、平台和架构本来就在新增 Host 时验证，此时继续只读探测并在 Host 卡片
+  提供手动准备入口最容易理解。
+- 项目只保存 Host ID、远端路径、Runtime 选择和默认工作模式。Agent installation、
+  Runtime digest、Workspace identity 和 Host revision 都从当次连接取得，不写入项目；
+  “移出安装”不等于“跳过当前环境检查”。
+
+目标职责是：
+
+| 流程 | 职责 |
+| --- | --- |
+| 新增或重新验证 Host | 验证身份和认证，保存 Host 并探测环境，不传输安装包 |
+| Host 管理 | 用户明确刷新目标 Host，并可选择安装、同版本重修、取消和重试 |
+| 创建远程项目 | 只读本地 Host 验证记录，保存时连接所选 Host 并验证当前 Agent、Workspace、Runtime 和模型配置，只持久化稳定配置 |
+| 切换远程项目 | 只切换本地项目配置，不连接 Host；实际使用 Workspace 或 Runtime 时按需复用 Host 当前环境 |
+
+## 不变量
+
+- Host 配置与远程环境准备是两个事务。SSH 验证成功后先原子保存 Host、凭据和完整 Host
+  Key，再开始可能耗时的下载和安装。
+- 环境准备失败或取消时保留已保存 Host，显示“未就绪”并允许重试，不创建半完成项目。
+- 不把“环境健康”保存为长期可信布尔值。设置页从 Host 的签名 registry 和当前 Host
+  identity 派生版本状态；准备完成和实际使用时再执行 bootstrap/health。合法但暂未运行的
+  detached Agent 仍可显示为已安装，打开设置不能为了刷新卡片隐式启动或更新它。
+- 所有安装继续使用 GoodBuddy-owned staging 和 side-by-side digest 目录。失败不得覆盖
+  可用旧安装，也不得删除 Host 上无关文件。
+- Renderer 不接收下载 URL、缓存路径、签名 key、digest、SSH 命令或凭据。Main 负责来源
+  选择、可信目录解析、操作编排和 IPC 输入校验。
+- 产品不提供“自动安装远程环境”开关。保存、重新验证或打开 Host 都不能自动传输
+  `.gbagent`；只有用户点击 Host 卡片的主按钮后，Main 才开始准备。
+- Host 卡片只有一个主按钮，按版本事实显示“安装远程环境”“更新远程环境”或“重新安装”。
+  次级 SegmentedControl 选择“自动”“Host 下载”或“GoodBuddy 传输”；默认“自动”，只影响
+  下一次操作，不持久化为 Host 配置。
+- “自动”只在 operation/prepare 前执行一次 Host capability probe：直连明确可用时选择
+  Host 下载，否则选择 GoodBuddy 传输。用户显式选择的方式保持有效；一旦 acquisition
+  已选定，prepare、commit 或 adoption 的任何失败都停止本次操作，不跨 acquisition
+  自动回退。
+- 直连安装只要求已验证 SSH 连接和远端系统工具，不要求现有 Agent daemon。轻量能力探测
+  返回确定性缺少工具、空间、权限或来源不可达时说明原因；探测本身异常时仍允许用户点击
+  直连安装，由实际安装流程重新解析签名候选并通过 SSH 重试。
+- 项目路径不得为了“方便”回退到隐式安装。Host 未就绪时应引导到 Host 设置，不在项目
+  切换器中启动大文件传输。
+
+## 新增 Host 流程
+
+新增向导保持现有 Host Key 和认证顺序，并在系统探针之后显示一次只读环境结果：
+
+1. 输入名称、地址、端口、用户名和认证方式。
+2. 在发送认证材料前读取并确认 Host Key。
+3. 完成 SSH 认证以及平台、架构、Shell、Home 有界探针。
+4. 原子保存 Host、加密凭据和完整 Host Key。
+5. 读取 Host 已安装的 Agent/Runtime registry，并执行一次轻量下载能力探测。
+6. 如果已安装 identity 满足当前 GoodBuddy 要求，显示“版本匹配”并结束；该 badge 不代表
+   Agent 正在运行或环境健康。
+7. 如果组件缺失或需要更新，显示目标 Agent、Node、Runtime、架构、来源和完整包大小，
+   告知用户保存后前往 Host 卡片安装，然后结束新增向导。
+
+新增流程到此结束，不显示自动安装开关，也不自动开始环境安装。保存后的 Host 卡片提供
+一个手动准备主按钮，并以次级 SegmentedControl 选择“自动”“Host 下载”或
+“GoodBuddy 传输”。主按钮按版本事实显示“安装远程环境”“更新远程环境”或“重新安装”。
+本地尚无精确包不要求用户先离开当前页面；选择 GoodBuddy 传输时，同一次操作会取得并
+验证候选后继续上传。
+
+探测不得自动下载完整 `.gbagent`。只有用户明确启动安装后才允许传输大包。
+
+## Host 编辑
+
+- 仅修改显示名称不要求重装远端环境。
+- 地址、端口、用户名或 Host Key 变化时，旧 Host identity 立即失效，关闭旧连接和对应
+  Runtime 缓存。项目记录不含旧组件 identity；下一次打开直接解析新 Host 的当前环境。
+  保存新身份后只重新执行环境探测，所需安装由用户在 Host 卡片手动启动。
+- 只替换同一目标的认证材料时仍重新认证并读取实际环境；如果签名 identity 和健康状态
+  未变化，不重复安装。
+- 当前项目引用的 Host 被编辑时，Main 立即失效该 Host 的 identity 和连接缓存；下一次
+  Workspace/Runtime 操作按需使用新目标。环境未准备好时该操作失败，不回退旧连接。
+
+## 下载能力探测
+
+探测在 Host Key 已固定且 SSH 认证成功后执行，只检查当前选择的“关于与更新”来源：
+
+- Host 是受支持的 Linux `x64` 或 `arm64`。
+- SSH 账号 Home 可写，GoodBuddy-owned staging 可创建。
+- 可用空间满足签名目录声明的包大小、解包上限和安全余量。
+- Host 可以通过 HTTPS 访问所选 GitHub 或北京镜像 URL。
+- 首次安装所需的下载、SHA-256 和运行归档内固定 Node 的能力可用。
+- 已安装 Agent 是否报告未来的直连更新能力。
+
+探测使用小型签名目录或有界请求，不以一次成功 `HEAD` 代替真实安装验证。结果只用于当次
+展示，不持久化为永久能力；开始安装前重新检查，因为网络、代理和磁盘状态可能变化。
+
+探测失败不能阻止保存 Host，也不能禁用显式 GoodBuddy 传输或离线导入路径。显式选择
+Host 下载时由实际操作报告不可用原因；“自动”只把“直连明确可用”作为选择 Host 下载的
+条件，其他结果选择 GoodBuddy 传输。
+
+## 工件选择与来源
+
+Main 继续读取并验证 `agent-catalog.json`、`agent-catalog.sig` 和 production 公钥
+registry，按以下条件选择唯一候选：
+
+- Host 平台和架构匹配；
+- 最低桌面版本满足；
+- Agent protocol major 相同，minor 不高于桌面支持值；
+- 使用满足条件的最高 SemVer；
+- URL、文件名、大小和 SHA-256 来自签名目录；
+- 下载来源跟随“关于与更新”的 GitHub/镜像选择。
+
+远程下载只优化大包的网络路径。Main 仍需先取得并验证小型目录，再通过经过 Host Key
+验证的 SSH 控制面传递固定候选元数据。产品不接受 Renderer、项目、Host 文件或用户输入的
+任意下载 URL。
+
+## 获取与统一安装事务
+
+首次安装不能假设 Host 已有 GoodBuddy Agent、installer 或系统 Node，也不由既有 Agent
+daemon 参与。两种 acquisition 的差别只在于如何把同一个签名 compound `.gbagent` 交付到
+固定 operation staging：
+
+- **Host 下载**：控制面通过固定 SSH prepare channel 发送签名目录绑定的 URL、大小和
+  SHA-256；Host 有界下载并校验完整归档。
+- **GoodBuddy 传输**：显式选择时，在线目录不可用或本地已验证包版本不低于在线候选，
+  则优先使用本地包，包括版本更高的离线导入；线上存在更新且可用时仍取得线上新包。
+  需要下载时，同一次用户操作会验证 SHA-256 和签名、写入缓存并取得 lease。随后以有界
+  流式 SFTP 上传一个 compound archive，以及从该归档中已验证的 bootstrap Node。约
+  294 MiB 的完整包不会一次读入 Main `Buffer`，Host 收到后仍再次校验完整包。
+
+交付后两种 acquisition 完全共用一个 control-plane 事务：
+
+1. Main 创建带 operation ID、总时限、输出上限和取消信号的准备操作，并通过固定
+   `prepare` channel 发送有界 one-shot installer 与结构化输入。
+2. Host 在解包写入准备目录的同一遍处理中校验归档大小、SHA-256、外层及内层签名、
+   平台、架构、协议和每个 payload digest；不再先完整扫描 payload、再重复解包和哈希。
+3. `commit` 只复核有界的签名 manifest、准备回执和入口 metadata，再以目录 rename 发布
+   已准备内容及包内认证的公钥 registry/Runtime lock；不会重读归档或遍历 payload。
+4. commit 后在同一条已固定身份的 SSH lease 上执行 Agent bootstrap/readiness 和 Runtime
+   activate。新 Agent 最多完整验证一次，新 Runtime 最多完整验证一次；注册成功后的
+   health、capabilities 和 prompt 启动只读取 registry、签名 manifest 与入口 metadata。
+5. Main 确认 adoption 后显式执行 cleanup。cleanup 失败不回滚已经健康的 Agent/Runtime，
+   也不阻塞下一次更新。
+
+这不是两个并行安装管理器，也不存在把 Agent 与 Runtime payload 逐文件走 SFTP 安装的
+第二条路径。两种 acquisition 共享相同的 prepare、commit、adoption、finalize 与 cleanup。
+
+Host 缺少可靠的下载、SHA-256 或 ZIP 能力时，不自动安装系统软件，也不要求 root。显式
+Host 下载返回明确失败；本次操作不自动切换 acquisition，用户可改选 GoodBuddy 传输后
+重新点击主按钮。后续更新和同版本重装复用同一事务，不要求用户先通过项目切换完成
+“过渡升级”。
+
+## 本机传输与离线路径
+
+现有 `.gbagent` 本地缓存、在线下载、离线导入和导出继续保留：
+
+- GoodBuddy 路径在本地缺少精确候选时，于同一次操作完成下载、整包大小与 SHA-256、
+  全部签名和 payload 验证、缓存发布及 lease 获取。
+- SFTP 有界流式上传单个 compound archive 与其中已验证的 bootstrap Node 到操作自己的
+  staging；Main 不把完整归档读入内存，Host 再次校验后进入统一 control-plane 事务。
+- Host 无公网、代理/TLS 异常或缺少 bootstrap 工具时，用户可显式使用此路径；离线导入
+  后也走同一缓存 lease、上传和 Host 校验流程。
+- 本地项目和普通桌面打包不依赖任何远端 Agent 工件。
+
+## 完整包与发布
+
+第一阶段继续发布和下载完整复合 `.gbagent`，不同时引入组件化增量发布：
+
+- 远程直连和 GoodBuddy 本机下载都会传输完整包，其中包含 Agent、固定 Node 和 OpenCode
+  Runtime。
+- 每次显式安装或重装都从本次已经校验并解包的准备目录原子替换对应 Agent 与 Runtime
+  digest 目录，不为节省本机磁盘写入而重新遍历旧目录，也不使用跨安装硬链接。
+- 操作中断后不续写旧 operation。下一次更新尽力清理其 staging，并从签名候选重新
+  prepare；正常 cleanup 随后删除本次准备目录。
+
+只有真实包体和发布频率证明网络成本仍不可接受时，才另行设计 Agent、Node 和 Runtime
+独立签名组件目录；本功能不提前引入第二套发布协议。
+
+## Host 准备状态
+
+设置中的 Host 卡片分开表达版本事实和操作结果：
+
+- **未验证**：Host Key、认证或系统探针尚未完成。
+- **尚未安装**：Host 可连接，但 Agent 或 Runtime 缺失。
+- **需要更新**：已安装 identity 与当前兼容候选不一致。
+- **正在准备**：正在探测、下载、验签、安装或健康检查。
+- **版本匹配**：版本 badge 只表示 Agent/Runtime identity 与当前兼容候选匹配，不等同于
+  进程正在运行或环境健康；设置页普通刷新不会启动已停止的 Agent。
+- **准备失败**：保留 Host 和可用旧组件，展示有界错误与重试入口。
+
+主按钮按版本事实显示“安装远程环境”“更新远程环境”或“重新安装”。重新安装失败后，
+界面显示本次操作未完成，并以随后重新检查的版本卡片表达当前事实，不在提交结果不确定时
+断言旧版本未被替换，也不得把“版本匹配”改称“环境健康”。统一进度以 `探测`、
+`下载/传输`、`校验`、`应用环境`、`Agent 激活与健康检查`、`Runtime 激活` 和
+`完成设置` 表达用户可理解的阶段。
+
+同一 Host identity 同时只允许一个由用户启动、Main-owned 的准备操作。重复观察者加入
+已有操作，不启动第二次发布；窗口关闭、显式取消、Host identity 改变或 Main 退出时执行
+有界取消。Main 只为该 Host 持久化一个不含凭据的 version-1 pending operation ID，用于
+下一次操作开始时尽力清理旧 staging。无论旧 cleanup 成功、目标已变化还是旧记录损坏，
+都删除这条可丢弃记录并开始 fresh prepare；不保存远端 metadata 副本，不续写旧 commit，
+也不跨重启恢复 adoption。当前操作中可确定的失败会立即尽力 cleanup。环境已健康后的
+cleanup 失败不回滚环境，也不阻塞下一次更新。
+
+## 项目创建与切换
+
+- 新建托管 SSH 项目弹窗只读取本地 Host Key/连接验证记录，不逐台连接或刷新版本。只有
+  已完成本地验证的 Host 可选；浏览目录或保存时才连接所选 Host，并由保存流程完整检查
+  Agent、Workspace 和 Runtime，但不隐式安装。
+- 项目保存验证 Host 当前 revision 与 Host Key generation、当前 Agent、Workspace、
+  Runtime、模型 profile 和 Ask/Execute 配置；SQLite 事务只写入 Host ID、规范远端路径、
+  Runtime 选择和默认工作模式。
+- 打开或切换已有项目只提交本地项目选择，不执行 SSH、registry、Workspace 或 Runtime
+  检查。首次实际使用远程 Workspace 或 Runtime 时才解析 Host 管理的当前 Agent/Runtime，
+  并建立或复用当前 Agent 连接。已安装 Agent 暂未运行时，
+  固定 `attach-or-bootstrap` 命令幂等启动 registry 中的 current identity；这里的
+  bootstrap 只启动进程，不安装组件，也不重新读取、哈希或验签完整 payload。
+  Agent 进程读取 Host 管理已提交的 registry 和匹配 manifest 元数据，不重新验签或扫描
+  完整安装 payload。
+- Workspace 和 Runtime 使用当前 Agent 连接产生的 live handle/lease。项目不保存或核对
+  历史 Workspace/Runtime identity；当前 registry、连接状态或 capability 无效时停止并
+  引导到 Host 管理，不在项目流程中下载或安装。
+- 桌面更新导致 Host 组件过旧时，项目保持未切换并提示前往 Host 设置。应用启动仍进入
+  第一个普通本地项目，不自动连接或更新远端 Host。
+- Host 环境更新成功后，Main 定向失效该 Host 的 Agent/Runtime identity、连接和 Runtime
+  会话缓存。所有项目在下一次实际操作时自然使用新的 current 环境；无需改写项目记录。
+- 环境准备失败时不改变已有项目绑定。Host identity 编辑失败时则继续保持 fail-closed，
+  因为旧身份不能替代用户刚保存的新身份。
+- 项目管理入口与项目选择分离。项目选择器中的浮动管理按钮直接打开目标项目设置；删除
+  不访问 Workspace、Agent 或 Host，因此远端目录已删除或 Host 不可达都不能阻止本地
+  项目记录清理。删除当前项目或 Host 级联删除当前项目时只回退到普通本地项目。
+- 项目选择器把托管 SSH 项目按已保存 Host 分组，并只读取 Main 当前持有的 Agent 连接
+  状态显示“未连接 / 连接中 / 就绪 / 异常”；打开菜单或读取状态不得隐式连接 Host。
+  Host 已承担类型与连接语义，项目副标题只显示远端工作目录。
+- Host 删除确认使用本地数据库列出全部引用项目，包括归档项目；确认后级联删除本地项目
+  及其会话、任务、成果、记忆、计划和心跳关联，再删除本地 Host 与凭据。整个流程不发起
+  SSH，也不删除远端内容；跨 Host 设置文件与 SQLite 的普通失败会恢复已写入的一侧。
+
+项目切换不展示远程激活进度，也不阻塞项目导航。`Host`、`Agent`、`Workspace`、`Runtime`
+和 `Saving` 进度只属于新建或显式保存项目；实际 Workspace/Runtime 操作使用正常的局部
+加载和错误反馈。
+
+## 实现结构
+
+当前实现复用现有机制，没有新增平行的安装管理器：
+
+- 扩展当前 Host 系统探针和远程环境 inspector，返回瞬时下载准备能力。
+- 让当前 `RemoteEnvironmentUpdateService` 演进为 Host 环境准备编排器，统一用户手动
+  启动的首次安装和后续更新、自动 acquisition 选择、进度、取消和最终失效。
+- Host 环境准备编排器直接完成一次 package prepare/commit 及 Agent/Runtime adoption。
+  Workspace 和执行路径只读取 current registry 并调用 Host 侧轻量 identity/health 检查，
+  在当前进程内复用已确认 identity 和 Agent 连接；Host 编辑或环境更新定向清空这些缓存。
+  这些路径不会取得安装包、发布组件或通过 SFTP 扫描 payload。
+- Host 卡片即使显示相同版本也保留显式重装操作，用于修复 registry、签名或 payload
+  identity 异常；若同一 digest 的 GoodBuddy-owned 目录校验失败，重装会先隔离旧目录，
+  并在原子 commit 失败时恢复旧目录。commit 成功后的 adoption 失败保留新发布内容，
+  下次重装清理旧暂存并重新 prepare/adopt。重装不要求删除 Host、凭据或项目，也不会
+  处理所有者异常、符号链接或非 GoodBuddy 管理路径。
+- 由桌面控制面打包有界 one-shot installer，并通过固定短命令 `exec sh -s` 和 stdin
+  发送脚本及结构化输入，避免 SSH command 长度限制；既有 package format v1 归档内固定
+  Node 负责解码和运行它。
+- Preload 只暴露明确的 Host 探测、准备、取消和进度方法，不暴露 URL 或任意 SSH 命令。
+- 现有 Agent/Runtime side-by-side、固定 SSH lease、Host 端一次完整验证、注册后轻量检查、
+  连接失效和项目稳定配置事务继续作为唯一实现。
+
+## 迁移
+
+- 已保存 Host 打开设置时只显示本地记录，不自动连接或检查版本；用户点击对应 Host 的
+  “刷新版本”后才执行只读状态探测。项目切换不依赖该按钮，也不建立连接。
+- 数据库升级保留远程项目、Host ID、远端路径、Runtime 选择及关联会话/任务，并删除旧的
+  Agent/Runtime/Workspace/Host 验证列和 Runtime 验证表。下一次实际远程操作从 Host
+  current 环境重新取得所有 live identity。
+- 如果 Host 未就绪或版本不兼容，项目仍可在本地选择，但实际远程操作失败；不再走旧的
+  隐式安装。
+- 已下载或导入的本地 `.gbagent` 保持可用，不能因加入远程直连而迁移或删除。
+- pending operation 保持 version 1，只记录 Host、目标 identity 与 operation ID，用于
+  尽力清理旧 staging；它不是远端环境状态或恢复日志。
+- 远程直连继续使用现有 package format version 1，不要求归档携带 installer，也不要求
+  目录声明额外的 bootstrap 能力元数据。
+
+## 验收标准
+
+1. 新 Host 保存和探测完成后不会自动下载、上传或安装任何包，也不存在自动安装开关；
+   再次进入 Host 设置不会逐台连接，只有显式“刷新版本”才探测目标 Host。
+2. Host 卡片只有一个按版本事实命名的主按钮；次级 SegmentedControl 提供默认且不持久化的
+   “自动”及显式“Host 下载”“GoodBuddy 传输”。没有预装 Agent、Node 或 Runtime 的 Host
+   可以完成准备；远程下载不可用时可手动改用 GoodBuddy 传输。
+3. 探测不下载完整包，失败不阻止保存 Host；非确定性探测失败不禁用直连重试，安装失败
+   或取消后 Host 仍可重试。
+4. 直接下载严格匹配签名目录中的 URL、大小和 SHA-256；GoodBuddy 传输可在同一次操作中
+   下载并验证缺失候选，以有界流式 SFTP 上传完整归档和已验证 bootstrap Node。Host 对
+   两者完成相同的外层与内层签名、路径、架构、协议和 payload 校验。
+5. Host 对本次候选只完成一次完整 payload 校验；commit、adoption、health、capabilities
+   和 prompt 启动不得再次遍历或哈希完整 Agent/Runtime，显式重装仍能用本次准备内容修复
+   同 digest 的损坏目录。
+6. 创建、打开和切换项目不会产生 `.gbagent` 下载、Agent payload SFTP 上传或安装目录发布。
+7. 未就绪 Host 不能创建远程项目；已有项目仍可本地选择，但远程操作失败并引导到 Host 设置。
+8. Host 编辑或更新后，引用项目使用 Host 管理的当前连接和 current registry，不读取项目
+   中的旧 Host/Agent/Runtime/Workspace identity；当前环境无效时才停止并要求在 Host 管理
+   中修复。
+9. Host 地址、用户或 Host Key 在准备期间变化时停止候选发布，旧身份不会被重新启用。
+10. GitHub、北京镜像、无公网 Host、取消、应用退出、磁盘不足、损坏下载和不支持架构均有
+   明确结果，且不触碰 GoodBuddy-owned 目录之外的文件。
+11. Linux x64 和 arm64 均通过 GitHub/北京镜像、取消、离线 GoodBuddy 传输，以及项目使用
+    Host current 环境执行 Workspace/Runtime 操作的真实 Host 测试；这些真实 Host 验收当前
+    仍待完成。
+12. Host 不可达或远端目录不存在时，用户仍可从项目浮动管理入口删除本地项目；删除 Host
+    会列出并本地清理全部关联项目，但不会连接 Host 或删除任何远端目录和内容。
+13. 中断或 adoption 失败后的下一次更新只尽力清理旧 staging，然后 fresh prepare；
+    pending record 不包含远端 metadata 副本。已健康环境的 cleanup 失败不触发回滚，
+    也不阻塞下一次更新。

+# GoodBuddy Release Runbook
+
+Read this runbook only when preparing, publishing, recovering, or verifying a
+desktop or GoodBuddy Agent release.
+
+This is an operator and CI procedure. It does not authorize adding application
+persistence, snapshots, journals, rollback engines, recovery protocols, or
+compatibility layers to automate release operations. Determine release recovery
+from the authoritative GitHub, OSS, workflow, and Git state, then use the
+smallest existing idempotent rerun or a new immutable version as specified
+below.
+
+## Release Packaging
+
+- Unless the user explicitly requests a local Windows package, never run local
+  Windows packaging or launch probes as part of release preparation. In
+  particular, do not run `npm run portable`, Windows
+  `npm run release:package`, direct `electron-builder` packaging, or launch a
+  locally packaged Windows app before publishing a release. Source validation
+  and the native GitHub Actions jobs are the release authorities.
+- After a release is published, confirm only that the expected Windows assets
+  exist in the public release metadata. Do not locally rebuild or launch the
+  Windows package, download or hash published installers, attach browser
+  automation to a packaged app, or perform exhaustive per-asset network probes
+  unless the user explicitly asks for that additional validation.
+- `.github/workflows/packages.yml` is the canonical cross-platform packaging
+  workflow. It validates and builds `out` once, then packages on six native
+  runners: Windows, macOS, and Linux, each for x64 and arm64.
+- The experimental Linux LoongArch (`loong64`) preview is built separately
+  through `build/loongarch-cross` by following
+  `docs/development/loongarch-preview-build.md`. It is not part of
+  `.github/workflows/packages.yml`, the six-runner GitHub Actions matrix,
+  standard release manifests, GitHub Release asset expectations, or the
+  production update index. Do not add it to those paths unless the user
+  explicitly requests a future production-support migration.
+- Run the unified packager with
+  `npm run release:package -- --platform <platform> --arch <arch>`. It only
+  packages for the native host and writes to
+  `dist/release/<platform>-<arch>`.
+- Default deliverables are NSIS and portable ZIP for Windows, DMG and ZIP for
+  macOS, and AppImage, DEB, and RPM for Linux. Every target includes
+  `release-manifest.json` with SHA-256 hashes.
+- `build/build-release.cjs` verifies the unpacked application, `app.asar`,
+  bundled Continue and OpenCode runtimes, executable architecture, and package
+  signatures before atomically replacing a release directory.
+- All desktop build paths, including local `portable`, package the Agent and
+  remote Runtime version locks plus the public signing-key registry without
+  embedding installable Linux Agent or remote Runtime payloads. Managed SSH is
+  optional: users explicitly download a compatible compound `.gbagent` package
+  from Settings or import one offline before GoodBuddy can install or update a
+  Host.
+- Each independently published Linux x64 or arm64 `.gbagent` contains the
+  Agent daemon, pinned Node, and the desktop-maintained compatible OpenCode
+  Runtime. Build both architectures on native GitHub Actions runners from one
+  immutable `agent-v<agentVersion>` tag.
+- Keep the GoodBuddy Agent source, shared protocol/contracts, runtime lock,
+  bundle tooling, and tests in this repository so a desktop commit identifies
+  the exact Agent source it expects. Do not create a separate Agent repository
+  or long-lived Agent release branch unless the Agent becomes an independently
+  released product serving multiple clients.
+- `.github/workflows/agents.yml` is the branch and pull-request build
+  verification workflow for GoodBuddy Agent. It must build Linux x64 and
+  arm64 on native runners from the checked-out commit, acquire the locked
+  official Node archive and locked OpenCode npm archive, verify every locked
+  digest, use only an ephemeral in-memory test signing identity, and verify the
+  resulting compound package and deterministic archive. It must not read
+  production signing secrets, publish installable release artifacts, or modify
+  the checked-in public key registry.
+- `.github/workflows/agent-release.yml` is the only production compound Agent
+  publication path. It requires an annotated immutable Agent tag, the protected
+  `agent-signing` Environment, native x64/arm64 builds, one production
+  GoodBuddy signing identity for every layer of the compound package and
+  catalog, a non-Latest GitHub Agent Release, and synchronized immutable
+  Beijing OSS objects plus the final signed latest-catalog pointer.
+- `.github/workflows/packages.yml` and `release:package` build only desktop
+  products. Missing Agent packages, remote Runtime inputs, or GoodBuddy signing
+  credentials must never block an ordinary desktop package or release.
+- Keep electron-builder invocations on `--publish never`. Main-branch builds
+  run validation and build the production bundle without running the native
+  package matrix. Manual builds upload 30-day GitHub Actions artifacts.
+  Version-tag builds verify and aggregate packages before publishing GitHub
+  Release assets. The macOS jobs sign, notarize, and verify packages when all
+  five Apple credentials are configured. With no Apple credentials they must
+  use the explicit `--unsigned` path, warn that Gatekeeper may block the
+  packages, and still complete; a partial credential set must fail rather than
+  silently downgrade.
+- Keep `ELECTRON_CACHE` and `ELECTRON_BUILDER_CACHE` under
+  `${{ runner.temp }}` in step-level workflow contexts. A cache beneath the
+  repository inherits the root `"type": "module"` and breaks electron-builder's
+  CommonJS macOS icon tool.
+- Tag builds must use `v${package.version}`. The workflow also supports manual
+  dispatch and main-branch changes to release tooling.
+
+### Agent Release Process
+
+- Agent releases use annotated `agent-v${agent-runtime-lock.agentVersion}` tags
+  and are separate from desktop `v${package.version}` releases. Confirm the
+  exact Agent release commit and tag with the user before creating or pushing
+  either.
+- The tagged commit must be reachable from protected `main`. The two native
+  jobs build the compound x64/arm64 packages from the same source and locks;
+  the catalog job rejects missing architectures, changed bytes for an existing
+  version/architecture identity, invalid prior signatures, and incompatible
+  matrix metadata.
+- Agent GitHub Releases are ordinary non-draft, non-prerelease releases but
+  must use `--latest=false`; they must never replace the desktop release marked
+  Latest. Publish immutable packages and the versioned catalog to
+  `agent-releases/v<agentVersion>/` in Beijing OSS, publish the GitHub Agent
+  Release, then atomically update the single `agent-releases/latest.json`
+  pointer to that version's immutable catalog and signature.
+- Do not report an Agent release complete until both public package
+  architectures match the signed catalog by size and SHA-256, the GitHub and
+  OSS catalog bytes/signatures are identical, the application can read the
+  selected source, and GitHub's repository Latest tag remains the desktop tag.
+
+### Tagged Release Process
+
+Every version-tag release must follow this sequence. A branch-only push does
+not require release notes.
+
+1. Confirm that the user wants a release tag and identify the exact release
+   commit and the new `package.json` version. Separately ask whether this
+   release should also receive an experimental LoongArch preview build; never
+   infer that choice from an earlier release.
+2. Find the latest stable version tag reachable before the release commit and
+   inspect the complete commit and file diff from that tag to the release
+   commit. For the first tagged release, inspect the relevant repository
+   history instead.
+3. Draft concise, user-facing release notes in both Simplified Chinese and
+   English based only on verified changes in that range. Use the titles
+   `GoodBuddy <version> 更新内容` and
+   `What's New in GoodBuddy <version>`, with corresponding `功能更新` /
+   `Features` and `问题修复` / `Bug Fixes` sections when applicable. The two
+   language versions must describe the same changes. Do not expose
+   internal-only details, credentials, private content, or unverified claims.
+4. Show the exact bilingual release-note draft to the user and wait for
+   explicit approval. If the release commit or either language version changes
+   after approval, inspect the updated tag range and request approval again.
+5. Write the approved notes to the single entry for the release version in
+   `resources/release-notes.json`. A failed unpublished candidate whose content
+   is carried forward must not retain a duplicate packaged entry.
+6. Verify that `package.json`, the root `package-lock.json` version, and
+   `package-lock.json.packages[""].version` all equal the release version. Run
+   `npm run release:notes:verify`, the required source validators, the
+   production build. The six native CI jobs remain the cross-platform
+   authority; do not add local packaging or packaged-app launch probes unless
+   the user explicitly requests them.
+   If the user requested a LoongArch preview in step 1, build it separately
+   from this exact candidate by following the LoongArch build document, record
+   its size and SHA-256, and keep it outside the standard GitHub/OSS release
+   asset set unless the user separately authorizes publishing it.
+7. Fetch both remotes immediately before tagging. Inspect any remote branch
+   movement instead of overwriting or silently merging it. Confirm the working
+   tree is clean, the candidate tag is unused locally and remotely, and the
+   exact approved commit has not changed.
+8. Only after all previous steps pass, create an annotated
+   `v${package.version}` tag at the exact approved commit. Push `main` to
+   `origin` and `github`, verify both branch SHAs, then push the tag to both
+   remotes and verify each peeled tag SHA (`refs/tags/<tag>^{}`) equals the
+   release commit.
+9. Keep both approved language versions as the single source for the GitHub
+   Release body and the packaged first-open release-notes modal. The modal
+   displays the release notes matching the current interface language and
+   contains no button linking to a full release page.
+10. Observe the tag workflow through publication and complete the public
+    verification checklist below. A successful push is not a completed
+    release.
+
+### OSS Publication Contract
+
+The tagged release job publishes through the GitHub Environment selected by
+`.github/workflows/packages.yml` (`aliyun-oss-release`) and reads the following
+effective GitHub Actions variables. Before a release or same-tag rerun can
+publish, verify that repository-, organization-, or environment-level
+resolution exposes:
+
+- `ALIYUN_OSS_BUCKET=goodbuddy`
+- `ALIYUN_OSS_ENDPOINT=https://oss-cn-beijing.aliyuncs.com`
+- a non-empty `ALIYUN_OIDC_PROVIDER_ARN` matching
+  `acs:ram::*:oidc-provider/*`
+- a non-empty `ALIYUN_ROLE_ARN` matching `acs:ram::*:role/*`
+
+For environment-scoped values, use the exact Environment name from the
+workflow; do not assume a similarly named UI environment such as `Production`
+contains the active variables.
+
+The Bucket and Endpoint are a deployment contract, not interchangeable
+examples. They must stay aligned with the trusted URL checks in
+`src/main/version-checker.ts`, `sites/app.js`, website validation, and related
+tests. A host, Bucket, Region, or CDN migration must update and validate every
+surface together before a new release.
+
+- Use GitHub OIDC and the RAM Role to obtain short-lived STS credentials.
+  Never add long-lived AccessKeys to repository or environment secrets.
+- Keep `ossutil` pinned. Its V4 signing requires the Region; derive it from the
+  canonical Endpoint, verify that the production value resolves to
+  `cn-beijing`, and pass `--region` to every `ossutil cp`, including the final
+  `latest.json` update.
+- Grant the RAM Role only the actions and prefixes required by the workflow.
+  It must be able to write immutable version objects and the final latest
+  pointer without granting unrelated administration privileges.
+- Upload release assets and `site-release.json` under the immutable
+  `releases/<tag>/` prefix first. Verify all 14 installer URLs publicly before
+  creating or publishing the GitHub Release. Update
+  `releases/latest.json` only after the GitHub Release is public and all prior
+  checks succeeded.
+- The expected GitHub Release contains 22 assets: 14 installers (two formats
+  for each Windows/macOS target and three formats for each Linux target), six
+  renamed target manifests, one aggregate `release-manifest.json`, and one `SHA256SUMS`.
+  `site-release.json` is an OSS publication artifact, not a GitHub Release
+  asset.
+
+### Failed Tag Recovery
+
+Classify a failed tag by the external side effects that completed before
+choosing a recovery:
+
+- If no source or release metadata must change, correct only the external
+  configuration and use **Re-run failed jobs** for the same immutable tag. Do
+  not change, move, delete, or recreate the tag.
+- If immutable OSS objects were partially uploaded but their source bytes are
+  unchanged, a same-tag rerun may idempotently re-upload or verify them. Never
+  point `latest.json` at a partially verified prefix.
+- If the GitHub Release is already public but the final latest-pointer step
+  failed, it is a published version. Keep its packaged notes and rerun the
+  failed release job for the same tag; do not classify it as an unpublished
+  candidate.
+- If code or release metadata must change, keep the failed tag immutable,
+  increment the patch version, obtain approval for the revised exact release
+  commit and notes, and create a new tag. Do not reuse the failed version.
+
+When recovering from a version tag whose workflow never published a public
+GitHub Release:
+
+- If a code or metadata change requires a higher version and a new tag, carry
+  the failed candidate's approved user-facing notes forward into the recovery
+  version, then remove the superseded failed version's entry from
+  `resources/release-notes.json`.
+- The packaged first-open modal must show that carried-forward content only
+  once under the recovery version. Never retain both the failed version and
+  its cumulative recovery copy, because users upgrading across them would see
+  duplicate content.
+- Never remove the packaged history for a version that successfully published
+  a GitHub Release. Verify the failed release state before treating an entry as
+  superseded.
+
+### Post-Publication Verification
+
+Do not report a release complete until all of the following are verified:
+
+1. The tag workflow and all six native package jobs succeeded. Verify the
+   recorded macOS signing mode: signed builds must pass `codesign`, `spctl`,
+   and `stapler`; unsigned builds must record the Gatekeeper caveat in the
+   Actions log and job summary. In the final release job, explicitly verify
+   the OSS configuration, OIDC authentication, release-index generation,
+   immutable upload, public asset check, GitHub Release publication, and
+   latest-pointer steps.
+2. The public GitHub Release is non-draft, non-prerelease, marked Latest, and
+   uses the expected tag and title. Its body must exactly match the Markdown
+   generated from the approved packaged bilingual notes.
+3. GitHub release metadata contains exactly the expected 22 uploaded asset
+   names, including the expected Windows x64 and arm64 assets. Do not download,
+   hash, launch, or send individual network probes to published installers
+   unless the user explicitly requests that additional validation.
+4. The Beijing `releases/latest.json` returns HTTP 200, has the expected stable
+   version, exact six targets and 14 installer entries, the trusted Beijing
+   URLs, and the GitHub fallback URL. It must match the immutable
+   `releases/<tag>/site-release.json`. Fetching and comparing these small JSON
+   metadata files is sufficient; rely on the successful publication job for
+   its per-asset public checks.
+5. The live website successfully fetches the index and produces the 14 correct
+   platform/architecture/format links from that metadata.
+6. Both remote `main` refs and both peeled tag refs still equal the approved
+   release commit, and the local working tree is clean.
+
+Never create or push a release tag, and never push a previously created
+release tag, before the release-note draft has received explicit approval.
+
+- Before a push that updates the `github` remote, ask whether the user wants a
+  release tag unless they already specified that choice. A branch-only push

+# GoodBuddy 产品、性能与体验综合改进计划
+
+## 文档信息
+
+| 项目 | 内容 |
+| --- | --- |
+| 文档类型 | 跨功能实施路线图 |
+| 状态 | 规划中 |
+| 版本 | 1.0 |
+| 日期 | 2026-08-31 |
+| 适用范围 | GoodBuddy Desktop、GoodBuddy Agent、发布与质量流程 |
+| 评审基线 | Desktop `0.11.13`、Agent lock `0.11.14` |
+
+## 1. 目的
+
+本文把 2026-08-31 对当前仓库进行的功能、性能、体验和交付评审结果整理为一份可分批实施、
+持续更新的权威清单。后续每一批工作都从本文选择明确范围，完成后更新状态、验证结果和相关
+产品文档，不再维护平行的临时待办。
+
+本计划优先完成已经存在但尚未形成真实用户闭环的能力，其次处理经过测量确认的性能问题，
+再安排依赖外部平台或产品选择的增强能力。实施继续遵循以下原则：
+
+1. 先保证完整、可用的生产路径，再扩展能力范围。
+2. 性能优化必须有基线、目标和优化后的对比数据。
+3. 复用现有合同、IPC、Worker、通知、错误边界和界面组件，不引入不必要的框架。
+4. Ask 保持只读；Execute 继续代表当前本机或 SSH 账号的完整授权。
+5. 每批只处理列明的范围，不借机进行无关重构。
+
+## 2. 明确排除的工作
+
+本计划**不包含初始 Renderer Bundle 优化**，包括但不限于：
+
+- 不为了缩小入口包继续拆分轻量同级页面。
+- 不单独延迟 KaTeX、全局样式或其他入口依赖。
+- 不调整现有 Bundle 预算来制造通过或失败。
+- 不以 Bundle 大小为理由改变当前页面交互语义。
+
+现有构建预算和按路由拆包继续作为回归保护保留。只有后续获得首屏解析或执行耗时证据，并由
+用户单独确认范围后，才重新讨论该项。

+龙芯包不加入上述正式索引，而使用独立 OSS 前缀：
+
+```text
+releases/
+└── loongarch-preview/
+    ├── latest.json
+    └── v<GoodBuddy 版本>/
+        ├── GoodBuddy-<版本>-linux-loong64-preview.deb
+        ├── preview-manifest.json
+        └── SHA256SUMS
+```
+
+版本目录不可变。先上传并公开验证三个版本对象，最后才覆盖
+`releases/loongarch-preview/latest.json`；不得把预览包放入 `releases/v*`、
+`releases/latest.json`、标准 GitHub Release 资产或桌面自动更新索引。
+版本对象建议使用 OSS Standard 存储、继承 Bucket 的公开读取策略，并设置长期
+immutable 缓存；`latest.json` 应使用 `application/json` 和短缓存或
+`no-cache`。`SHA256SUMS` 必须只记录 DEB 文件名，不得记录构建容器绝对路径。
+
+官网只读取以下严格结构，且仅接受北京 OSS
+`releases/loongarch-preview/v<goodBuddyVersion>/` 下的精确 HTTPS 地址：
+
+```json
+{
+  "formatVersion": 1,
+  "product": "GoodBuddy LoongArch Preview",
+  "goodBuddyVersion": "0.11.5",
+  "previewVersion": "0.11.5-loong64-preview.1",
+  "architecture": "loong64",
+  "format": "deb",
+  "artifact": {
+    "name": "GoodBuddy-0.11.5-linux-loong64-preview.deb",
+    "size": 186853872,
+    "sha256": "672321e314fbdb91c6d7b2b549a838e556bd7e597746a3e6d346b936f2ff8369",
+    "url": "https://goodbuddy.oss-cn-beijing.aliyuncs.com/releases/loongarch-preview/v0.11.5/GoodBuddy-0.11.5-linux-loong64-preview.deb"
+  },
+  "manifestUrl": "https://goodbuddy.oss-cn-beijing.aliyuncs.com/releases/loongarch-preview/v0.11.5/preview-manifest.json",
+  "checksumUrl": "https://goodbuddy.oss-cn-beijing.aliyuncs.com/releases/loongarch-preview/v0.11.5/SHA256SUMS"
+}
+```
+
+上传仍应使用 GitHub OIDC 获取的短期 STS 凭据和固定 `ossutil 2.3.0`，Bucket
+为 `goodbuddy`，Endpoint 为 `https://oss-cn-beijing.aliyuncs.com`，Region
+为 `cn-beijing`。上传版本对象前先读取目标对象元数据：不存在时才上传，已存在
+且大小和 SHA-256 相同时跳过，任一字节不同时必须停止；`--update` 只用于传输
+优化，不能代替不可变性检查。也可为版本前缀启用 OSS 保留策略/WORM。指针仅在
+所有公开 GET、大小、SHA-256、manifest 和 DEB 元数据检查通过后使用
+`--force` 更新。手工上传时也应遵循同一顺序，不使用长期 AccessKey。
+
+若独立索引不存在、超时、过大、字段多缺、版本不稳定、摘要格式错误或任一
+URL 不匹配受信任前缀，中文官网选择龙芯处理器时会保持下载按钮禁用；Linux
+x64 / arm64 及另外两个正式平台入口不受影响。英文页面继续只展示正式
+GitHub Release。
