Keep workspace `engines.node` declarations and [the launcher preflight](packages/runtime/check-node-version.cjs) aligned.

Use `pnpm format` for all TS/TSX/MTS/CTS files and `pnpm format:check` for a read-only check. For selected files, run `pnpm exec eslint --config eslint.format.config.ts --fix ` followed by `pnpm exec prettier --write `. These commands enforce four-space indentation, braces around control-statement bodies, and blank lines around statement blocks while preserving other logical spacing. They are separate from CI and its code-quality lint rules. Generated catalogs and compiler fixtures retain their source formatting. + +Use focused tests while iterating. Before handing off a code change, run the full checks required by CONTRIBUTING.md and report anything that could not run. [PR CI](.github/workflows/ci.yml) is the reference; `pnpm run ci` reproduces its commands locally, including dependency installation and the generated-catalog check. + +- **Documentation-only changes:** verify links, paths, commands and `git diff --check`; runtime tests do not validate prose. +- **Shared types or actions:** run workspace typechecking as well as behavior tests. A passing Vitest run does not prove type correctness. +- **SDK packaging:** keep the SDK's `NodeNext` build and explicit `.js` relative imports, including type-only exports. Its package tests compile fresh output and check native Node.js imports, consumer declarations, and complete action-map coverage. The SDK action catalog must match OneBot's executable names; `packages/onebot/tests/sdk-actions.test.ts` checks this without adding a runtime dependency on server code. SDK parameter/result contracts remain independent of server types; keep consumer examples under `packages/sdk/tests/fixtures` aligned with the server parser checks in `packages/onebot/tests/sdk-action-params.test.ts`. +- **SDK streams:** preserve the single-response client methods and use the additive interfaces in [STREAMING.md](packages/sdk/STREAMING.md) for file transfers. Test framing, cancellation, bounded buffering and incomplete transfers in the SDK; `packages/onebot/tests/sdk-streaming.test.ts` checks real adapter/handler round trips in temporary storage without QQ. +- **SDK reverse WebSocket:** Node-only listeners accept OneBot implementation connections, never substitute an outgoing SDK client for a protocol implementation. Reuse the shared client session for actions/events/streams and preserve per-account identity, API/Event pairing, bounded buffers and pending-request rejection on disconnect. Test the real runtime reverse adapter and fresh published imports; see [REVERSE_WEBSOCKET.md](packages/sdk/REVERSE_WEBSOCKET.md). +- **SDK messaging:** preserve existing string-path and ordinary reply semantics when extending the helpers in [MESSAGING.md](packages/sdk/MESSAGING.md). Filesystem access belongs only in the optional `@snowluma/sdk/node` entry point. Media sends must await upload completion and retain failure context without automatic retries; event waits follow public middleware dispatch and release listeners on every outcome. Keep legacy handler/context types assignable when adding richer SDK-created contexts. +- **MCP agents:** preserve existing text results, business-error envelopes, default search matching and mode gates when extending the tools. Use the server SDK's `serveStdio` entry to support modern discovery and legacy initialization from the same command; test both with freshly compiled output. Cache hints belong only on bundled catalog discovery, never execution or account data. Keep trace metadata out of action parameters and sensitive data out of diagnostics. Protocol compatibility, tracing and the additive agent features are documented in [AGENT_FEATURES.md](packages/mcp/AGENT_FEATURES.md). Use isolated HTTP and MCP transports in tests; local runtime inspection must not query a live account. +- **MCP execution services:** keep background tasks and event connections opt-in. Persist task state before effects, never replay interrupted writes, and finish durable cleanup before draining the protocol on shutdown. Input continuations must retain their original arguments and execute at most once. Event buffers require explicit account binding, bounded storage and visible gaps. Build the bundled message preview through `packages/mcp/scripts/build-message-app.mjs`; loading a preview must not send a message. Test restart, cancellation and legacy compatibility using isolated transports, including the compiled CLI. +- **Protocol codecs:** keep the existing Proton integration in tests so they exercise the same transformations as production. Import real implementations; do not duplicate the algorithm in the test. +- **Video uploads:** preserve the single-connection default and the additive global setting in [HIGHWAY_UPLOADS.md](packages/protocol/HIGHWAY_UPLOADS.md). Only video bodies opt into parallel chunks. Confirm every chunk before completion, bound both concurrency and lookahead, and drain outstanding reads and requests before closing the source. Keep retries bounded and backpressure changes visible. Test the actual uploader with isolated transports; passing tests do not prove live throughput. +- **Highway upload recovery:** all chunks and workers share one file transfer deadline. Keep node observations bounded, short-lived and isolated by account session, upload type and full host/port; select only current server-supplied candidates. Only validated acknowledgements establish success. Preserve terminal failure reporting and drain pending file reads after cancellation. Test deadline cleanup and candidate rotation with isolated transports, including real loopback sockets; see [upload policy](packages/protocol/HIGHWAY_UPLOADS.md#upload-timeouts-and-node-selection). +- **Native coverage:** `pnpm test:native` is separate from default protocol tests and requires compatible native artifacts. A missing artifact or unavailable target is a reported limitation, not permission to bypass the check. +- **OneBot SSE:** HTTP event streams share the HTTP adapter's binding and authentication. Preserve account isolation, bounded replay, visible expired-cursor errors, report filtering and slow-reader limits described in [HTTP_SSE.md](packages/onebot/HTTP_SSE.md). Token/report-policy changes revoke existing streams and invalidate replay; test shutdown and reload with active connections. +- **Live QQ behavior:** fixture tests and a successful API response do not prove delivery or client rendering. State what was tested locally and what still needs a real client. + +`pnpm dev` starts Core and can attach to local QQ processes; use it only when runtime testing is intended. `pnpm dev:web` starts the frontend, which expects a WebUI backend. Follow the existing test fakes for isolated work rather than starting a live account unnecessarily. + +WebUI deployment targets use a reversible presentation overlay. Read [the host appearance contract](packages/webui/INTEGRATIONS.md) before changing it. Keep target validation in `@snowluma/common/webui-target`, implementations in the frontend target registry, and saved preferences separate from effective appearance. Default deployments must not load target assets or host listeners; do not put target-name branches in business pages. + +## Implementation rules + +- **Fix the cause.** Reproduce failures at the owning layer and add a regression test for the observable behavior. Avoid account-, filename-, or example-specific patches. +- **Make errors observable.** Do not turn exceptions into empty results or successful responses. Preserve error context and use the shared logger for important transitions and failures. If evidence is insufficient, add targeted diagnostics and describe what remains unknown. +- **Preserve account isolation.** Identity, message storage and session state belong to their account. Keep teardown ordering and in-flight work handling intact when changing lifecycle code. +- **Keep parsing separate from effects.** QQ decoders and OneBot event converters translate data. Live state updates belong to their owning pipeline or service; reading history must not mutate live membership or pending requests. +- **Use the declared interfaces.** OneBot consumes the [Bridge interface](packages/core/src/bridge/bridge-interface.ts). Reuse package exports and existing dependency injection instead of reaching into another owner's state or building a second registry. +- **Validate at inputs.** Use the existing action field and cross-field validation helpers. Preserve accepted input forms, response fields and error behavior unless the change explicitly calls for new semantics. Do not silently discard invalid outbound message content. +- **Preserve signed message IDs.** OneBot `message_id` / `messageId` values generated by [message-id.ts](packages/onebot/src/message-id.ts) are non-zero signed 32-bit integers; negative values are valid. Use `f.messageId()` for action inputs and preserve the value through storage, replies, lookups and result matching. Protocol representations must be converted losslessly at their boundary; changing the sign or generation rule changes existing message identities. +- **Protect persisted data.** Message history and media metadata are durable records. Do not add automatic deletion or treat them as disposable caches. Migration changes need failure and restart coverage; keep failures visible. +- **Preserve transport policy.** Retain configured bind addresses and access checks. TLS startup failure must not silently downgrade to HTTP. Distinguish saved configuration from changes actually applied to a running adapter. +- **Keep types and ownership clear.** Follow the strict TypeScript configuration, existing import style and four-space TypeScript indentation. Validate unknown external data instead of hiding mismatches with casts or fallback values. Keep comments about reasons and non-obvious behavior. +- **Keep diagnostics safe.** Use existing sanitization when recording external input. Credentials, private keys, private account data and unredacted captures do not belong in commits, fixtures or public reports. + +## Generated files and related changes + +OneBot action definitions own validation and catalog metadata. Each bundled action supplies a `returnsSchema` for successful OneBot `data` and at least one `examples` entry with valid parameters and any required identifier sources. Stream schemas describe individual successful frames, not MCP aggregated results. Keep undocumented upstream fields open rather than inventing a structure, and label unsupported or placeholder behavior explicitly. + +After changing an action name, parameter, result description/schema, example or execution mode: + +1. Update the owning definition in `packages/onebot/src/actions` and its tests. +2. Run `pnpm --filter @snowluma/mcp gen`. +3. Inspect and include the corresponding changes in `packages/mcp/src/generated/catalog.ts` and `catalog.json`. Do not hand-edit generated catalog entries. +4. Check affected SDK types and callers, run their relevant tests, and run workspace typechecking. + +`pnpm test` also runs the MCP catalog generator and may change these tracked snapshots. CI's `node tools/check-action-catalog.mjs` rejects a working-tree catalog diff; it is a clean-checkout drift check, not the generator itself. + +SDK breaking changes also update [CHANGELOG.md](packages/sdk/CHANGELOG.md) and [VERSIONING.md](packages/sdk/VERSIONING.md). WebUI changes follow its [interaction conventions](packages/webui/README.md). Keep user-facing documentation aligned with behavior. + +Standalone WebUI branding uses the [SnowLuma mascot](assets/readme/mascot.png) and a lavender default accent. The default palette lightly tints neutral surfaces with the active accent, respecting sidebar-only scope and OLED black. Keep server defaults, frontend presets and pre-mount CSS aligned as described in [WebUI default appearance](packages/webui/README.md#default-appearance), while preserving saved user choices, named palettes and host appearance overlays. + +The root [README.md](README.md) presents the project's purpose, overall capabilities, quick start and documentation entry points. Update it only when those overview details change; adding or fixing an individual feature does not justify adding a dedicated section there. Put feature-specific API usage, configuration, limitations and troubleshooting in the relevant package README or topic document, preferring existing documentation. + +Edit sources rather than `dist` outputs. Native artifacts in `packages/runtime/native` are supplied build inputs; do not substitute arbitrary local binaries to make a build pass. Packaging changes must preserve the checks in [Core's build configuration](packages/core/vite.config.ts) and [the release layout validator](tools/check-release-layout.mjs). + +## Handoff and instruction maintenance + +Report the behavior changed, the exact validation commands and results, and any unverified runtime or platform behavior. Keep public PR and commit text focused on the contribution; omit local environment details and private research. Use English Conventional Commit messages as described in CONTRIBUTING.md. + +`AGENTS.md` is the canonical contributor guide; `CLAUDE.md` is a relative symlink to it. Edit this file once. When package ownership, validation commands or contribution policy changes, update the affected instructions in the same change. Link to checked-in sources and keep the guide usable from a fresh clone without maintainer-local notes, tools or absolute paths. diff --git a/CHANGELOG.md b/CHANGELOG.md new file mode 100644 index 00000000..08f4ac7c --- /dev/null +++ b/CHANGELOG.md @@ -0,0 +1,19 @@ +# 更新记录 + +## 2.0.0 + +### 升级 + +- 最低运行环境升至 Node.js 24。完整版内置 Node.js；Lite、SDK 和 MCP 用户需先升级运行环境。 +- 原生接口全面异步化，应用与原生产物需成套更新；请使用对应平台的完整发行包。 + +### 更新 + +- 新增本地 QQ 账号识别、进程状态诊断和有序账号通知。 +- WebUI 支持暂存更新、重启安装，并保留配置、日志与消息数据。 +- 新增群分享链接、空间说说详情与评论分页接口，同步 SDK 类型和 MCP 动作目录。 +- 改进合并转发引用预览、群相册评论、SILK 时长和 Highway 节点切换。 +- 整理原生调用、SQLite、账号关闭和重连顺序，修复请求取消、订阅和定时器释放。 +- 减少 WebUI 空闲轮询，修复反向代理认证与版本比较。 + +[查看自 v1.14.22 起的完整差异](https://github.com/SnowLuma/SnowLuma/compare/v1.14.22...dev) diff --git a/CLAUDE.md b/CLAUDE.md new file mode 100644 index 00000000..1354e06d --- /dev/null +++ b/CLAUDE.md @@ -0,0 +1,135 @@ +# Working on SnowLuma + +SnowLuma translates QQ client sessions into OneBot v11 actions and events, with a WebUI, TypeScript SDK, and MCP server.

Versions must be canonical SemVer; strip GitHub's `v` tag prefix only at the API boundary. + +Read the relevant owner before changing a path: + +| Change | Start here | +| --- | --- | +| Connection or account lifecycle | [Hook manager](packages/bridge/src/hook-manager.ts), [Bridge manager](packages/core/src/bridge/manager.ts), [OneBot instance](packages/onebot/src/instance.ts) | +| Which account a QQ process is signed in as | [Account detection](packages/bridge/src/qq-account/detect.ts), [login.db reader](packages/bridge/src/qq-account/login-db.ts), [QQ data paths](packages/bridge/src/qq-account/paths.ts) | +| Incoming QQ events or identity | [Packet pipeline](packages/protocol/src/packet-pipeline.ts), [message decoders](packages/protocol/src/msg-push/index.ts), [identity service](packages/protocol/src/identity-service.ts) | +| OneBot actions or message segments | [Action definitions](packages/onebot/src/actions/index.ts), [validation helpers](packages/onebot/src/action-kit.ts), [event conversion](packages/onebot/src/event-converter/index.ts) | +| WebUI | [Interaction conventions](packages/webui/README.md), `packages/webui/src`, `packages/core/src/webui` | +| SDK or MCP | [SDK guide](packages/sdk/README.md), [SDK versioning](packages/sdk/VERSIONING.md), [MCP guide](packages/mcp/README.md) | +| Protocol codec generation | [Proton guide](packages/proton/README.md), the affected package's `vitest.config.ts` | + +## Setup and validation + +Use the Node version in [.node-version](.node-version) and the pnpm version in [package.json](package.json). Install with `pnpm install --frozen-lockfile`; keep the existing lockfile unless changing dependencies. + +The Node security baseline is `^24.22.1 || >=26.12.1`; older 24.x releases, 25.x and unpatched 26.x releases are unsupported. Keep workspace `engines.node` declarations and [the launcher preflight](packages/runtime/check-node-version.cjs) aligned. CI and bundled releases use `.node-version`; raising that pin alone does not upgrade an existing installation's runtime. + +Run commands from the repository root: + +```sh +pnpm typecheck # all workspace packages with a typecheck script +pnpm lint +pnpm test # workflow policy checks and workspace tests +pnpm test:workflows # isolated PR policy tests; no GitHub writes +pnpm run build:all # release inputs and published packages +pnpm test:core # Core only; not a substitute for workspace tests +pnpm --filter @snowluma/onebot test # example: tests for the affected package +pnpm --filter webui test # the frontend package has no @snowluma/ prefix +``` + +TypeScript formatting uses the root [Prettier configuration](.prettierrc.json), [local ESLint formatting rules](eslint.format.config.ts), and [ignore list](.prettierignore). Use `pnpm format` for all TS/TSX/MTS/CTS files and `pnpm format:check` for a read-only check. For selected files, run `pnpm exec eslint --config eslint.format.config.ts --fix ` followed by `pnpm exec prettier --write `. These commands enforce four-space indentation, braces around control-statement bodies, and blank lines around statement blocks while preserving other logical spacing. They are separate from CI and its code-quality lint rules. Generated catalogs and compiler fixtures retain their source formatting. + +Use focused tests while iterating. Before handing off a code change, run the full checks required by CONTRIBUTING.md and report anything that could not run. [PR CI](.github/workflows/ci.yml) is the reference; `pnpm run ci` reproduces its commands locally, including dependency installation and the generated-catalog check. + +- **Documentation-only changes:** verify links, paths, commands and `git diff --check`; runtime tests do not validate prose. +- **Shared types or actions:** run workspace typechecking as well as behavior tests. A passing Vitest run does not prove type correctness. +- **SDK packaging:** keep the SDK's `NodeNext` build and explicit `.js` relative imports, including type-only exports. Its package tests compile fresh output and check native Node.js imports, consumer declarations, and complete action-map coverage. The SDK action catalog must match OneBot's executable names; `packages/onebot/tests/sdk-actions.test.ts` checks this without adding a runtime dependency on server code. SDK parameter/result contracts remain independent of server types; keep consumer examples under `packages/sdk/tests/fixtures` aligned with the server parser checks in `packages/onebot/tests/sdk-action-params.test.ts`. +- **SDK streams:** preserve the single-response client methods and use the additive interfaces in [STREAMING.md](packages/sdk/STREAMING.md) for file transfers. Test framing, cancellation, bounded buffering and incomplete transfers in the SDK; `packages/onebot/tests/sdk-streaming.test.ts` checks real adapter/handler round trips in temporary storage without QQ. +- **SDK reverse WebSocket:** Node-only listeners accept OneBot implementation connections, never substitute an outgoing SDK client for a protocol implementation. Reuse the shared client session for actions/events/streams and preserve per-account identity, API/Event pairing, bounded buffers and pending-request rejection on disconnect. Test the real runtime reverse adapter and fresh published imports; see [REVERSE_WEBSOCKET.md](packages/sdk/REVERSE_WEBSOCKET.md). +- **SDK messaging:** preserve existing string-path and ordinary reply semantics when extending the helpers in [MESSAGING.md](packages/sdk/MESSAGING.md). Filesystem access belongs only in the optional `@snowluma/sdk/node` entry point. Media sends must await upload completion and retain failure context without automatic retries; event waits follow public middleware dispatch and release listeners on every outcome. Keep legacy handler/context types assignable when adding richer SDK-created contexts. +- **MCP agents:** preserve existing text results, business-error envelopes, default search matching and mode gates when extending the tools. Use the server SDK's `serveStdio` entry to support modern discovery and legacy initialization from the same command; test both with freshly compiled output. Cache hints belong only on bundled catalog discovery, never execution or account data. Keep trace metadata out of action parameters and sensitive data out of diagnostics. Protocol compatibility, tracing and the additive agent features are documented in [AGENT_FEATURES.md](packages/mcp/AGENT_FEATURES.md). Use isolated HTTP and MCP transports in tests; local runtime inspection must not query a live account. +- **MCP execution services:** keep background tasks and event connections opt-in. Persist task state before effects, never replay interrupted writes, and finish durable cleanup before draining the protocol on shutdown. Input continuations must retain their original arguments and execute at most once. Event buffers require explicit account binding, bounded storage and visible gaps. Build the bundled message preview through `packages/mcp/scripts/build-message-app.mjs`; loading a preview must not send a message. Test restart, cancellation and legacy compatibility using isolated transports, including the compiled CLI. +- **Protocol codecs:** keep the existing Proton integration in tests so they exercise the same transformations as production. Import real implementations; do not duplicate the algorithm in the test. +- **Video uploads:** preserve the single-connection default and the additive global setting in [HIGHWAY_UPLOADS.md](packages/protocol/HIGHWAY_UPLOADS.md). Only video bodies opt into parallel chunks. Confirm every chunk before completion, bound both concurrency and lookahead, and drain outstanding reads and requests before closing the source. Keep retries bounded and backpressure changes visible. Test the actual uploader with isolated transports; passing tests do not prove live throughput. +- **Highway upload recovery:** all chunks and workers share one file transfer deadline. Keep node observations bounded, short-lived and isolated by account session, upload type and full host/port; select only current server-supplied candidates. Only validated acknowledgements establish success. Preserve terminal failure reporting and drain pending file reads after cancellation. Test deadline cleanup and candidate rotation with isolated transports, including real loopback sockets; see [upload policy](packages/protocol/HIGHWAY_UPLOADS.md#upload-timeouts-and-node-selection). +- **Native coverage:** `pnpm test:native` is separate from default protocol tests and requires compatible native artifacts. A missing artifact or unavailable target is a reported limitation, not permission to bypass the check. +- **OneBot SSE:** HTTP event streams share the HTTP adapter's binding and authentication. Preserve account isolation, bounded replay, visible expired-cursor errors, report filtering and slow-reader limits described in [HTTP_SSE.md](packages/onebot/HTTP_SSE.md). Token/report-policy changes revoke existing streams and invalidate replay; test shutdown and reload with active connections. +- **Live QQ behavior:** fixture tests and a successful API response do not prove delivery or client rendering. State what was tested locally and what still needs a real client. + +`pnpm dev` starts Core and can attach to local QQ processes; use it only when runtime testing is intended. `pnpm dev:web` starts the frontend, which expects a WebUI backend. Follow the existing test fakes for isolated work rather than starting a live account unnecessarily. + +WebUI deployment targets use a reversible presentation overlay. Read [the host appearance contract](packages/webui/INTEGRATIONS.md) before changing it. Keep target validation in `@snowluma/common/webui-target`, implementations in the frontend target registry, and saved preferences separate from effective appearance. Default deployments must not load target assets or host listeners; do not put target-name branches in business pages. + +## Implementation rules + +- **Fix the cause.** Reproduce failures at the owning layer and add a regression test for the observable behavior. Avoid account-, filename-, or example-specific patches. +- **Make errors observable.** Do not turn exceptions into empty results or successful responses. Preserve error context and use the shared logger for important transitions and failures. If evidence is insufficient, add targeted diagnostics and describe what remains unknown. +- **Preserve account isolation.** Identity, message storage and session state belong to their account. Keep teardown ordering and in-flight work handling intact when changing lifecycle code. +- **Keep parsing separate from effects.** QQ decoders and OneBot event converters translate data. Live state updates belong to their owning pipeline or service; reading history must not mutate live membership or pending requests. +- **Use the declared interfaces.** OneBot consumes the [Bridge interface](packages/core/src/bridge/bridge-interface.ts). Reuse package exports and existing dependency injection instead of reaching into another owner's state or building a second registry. +- **Validate at inputs.** Use the existing action field and cross-field validation helpers. Preserve accepted input forms, response fields and error behavior unless the change explicitly calls for new semantics. Do not silently discard invalid outbound message content. +- **Preserve signed message IDs.** OneBot `message_id` / `messageId` values generated by [message-id.ts](packages/onebot/src/message-id.ts) are non-zero signed 32-bit integers; negative values are valid. Use `f.messageId()` for action inputs and preserve the value through storage, replies, lookups and result matching. Protocol representations must be converted losslessly at their boundary; changing the sign or generation rule changes existing message identities. +- **Protect persisted data.** Message history and media metadata are durable records. Do not add automatic deletion or treat them as disposable caches. Migration changes need failure and restart coverage; keep failures visible. +- **Preserve transport policy.** Retain configured bind addresses and access checks. TLS startup failure must not silently downgrade to HTTP. Distinguish saved configuration from changes actually applied to a running adapter. +- **Keep types and ownership clear.** Follow the strict TypeScript configuration, existing import style and four-space TypeScript indentation. Validate unknown external data instead of hiding mismatches with casts or fallback values. Keep comments about reasons and non-obvious behavior. +- **Keep diagnostics safe.** Use existing sanitization when recording external input. Credentials, private keys, private account data and unredacted captures do not belong in commits, fixtures or public reports. + +## Generated files and related changes + +OneBot action definitions own validation and catalog metadata. Each bundled action supplies a `returnsSchema` for successful OneBot `data` and at least one `examples` entry with valid parameters and any required identifier sources. Stream schemas describe individual successful frames, not MCP aggregated results. Keep undocumented upstream fields open rather than inventing a structure, and label unsupported or placeholder behavior explicitly. + +After changing an action name, parameter, result description/schema, example or execution mode: + +1. Update the owning definition in `packages/onebot/src/actions` and its tests. +2. Run `pnpm --filter @snowluma/mcp gen`. +3. Inspect and include the corresponding changes in `packages/mcp/src/generated/catalog.ts` and `catalog.json`. Do not hand-edit generated catalog entries. +4. Check affected SDK types and callers, run their relevant tests, and run workspace typechecking. + +`pnpm test` also runs the MCP catalog generator and may change these tracked snapshots. CI's `node tools/check-action-catalog.mjs` rejects a working-tree catalog diff; it is a clean-checkout drift check, not the generator itself. + +SDK breaking changes also update [CHANGELOG.md](packages/sdk/CHANGELOG.md) and [VERSIONING.md](packages/sdk/VERSIONING.md). WebUI changes follow its [interaction conventions](packages/webui/README.md). Keep user-facing documentation aligned with behavior. + +Standalone WebUI branding uses the [SnowLuma mascot](assets/readme/mascot.png) and a lavender default accent. The default palette lightly tints neutral surfaces with the active accent, respecting sidebar-only scope and OLED black. Keep server defaults, frontend presets and pre-mount CSS aligned as described in [WebUI default appearance](packages/webui/README.md#default-appearance), while preserving saved user choices, named palettes and host appearance overlays. + +The root [README.md](README.md) presents the project's purpose, overall capabilities, quick start and documentation entry points. Update it only when those overview details change; adding or fixing an individual feature does not justify adding a dedicated section there. Put feature-specific API usage, configuration, limitations and troubleshooting in the relevant package README or topic document, preferring existing documentation. + +Edit sources rather than `dist` outputs. Native artifacts in `packages/runtime/native` are supplied build inputs; do not substitute arbitrary local binaries to make a build pass. Packaging changes must preserve the checks in [Core's build configuration](packages/core/vite.config.ts) and [the release layout validator](tools/check-release-layout.mjs). + +## Handoff and instruction maintenance + +Report the behavior changed, the exact validation commands and results, and any unverified runtime or platform behavior. Keep public PR and commit text focused on the contribution; omit local environment details and private research. Use English Conventional Commit messages as described in CONTRIBUTING.md. + +`AGENTS.md` is the canonical contributor guide; `CLAUDE.md` is a relative symlink to it. Edit this file once. When package ownership, validation commands or contribution policy changes, update the affected instructions in the same change. Link to checked-in sources and keep the guide usable from a fresh clone without maintainer-local notes, tools or absolute paths. diff --git a/CODE_OF_CONDUCT.md b/CODE_OF_CONDUCT.md new file mode 100644 index 00000000..1331434a --- /dev/null +++ b/CODE_OF_CONDUCT.md @@ -0,0 +1,90 @@ +# 贡献者公约 (Contributor Covenant Code of Conduct) + +本文档改编自 [Contributor Covenant v2.1](https://www.contributor-covenant.org/version/2/1/code_of_conduct/)，是 SnowLuma 社区共同遵守的行为准则。 + +## 我们的承诺 + +身为社区成员、贡献者、维护者，我们承诺：让每一个参与 SnowLuma 项目和社区的人，不因年龄、体型、可见或不可见的身体差异、身心障碍、族裔、性别特征、性别认同与表达、经验水平、教育背景、社会经济地位、国籍、外貌、种族、宗教信仰、或性取向，而遭受骚扰。 + +我们承诺以营造开放、热情、多元、包容、健康社区的方式行事和互动。 + +## 我们的准则 + +有助于建立正向社区环境的行为包括但不限于： + +- 对他人展现同理心与善意 +- 尊重不同的意见、观点与经验 +- 给予并优雅地接受建设性反馈 +- 承担责任并向受我们错误影响的人致歉，并从中吸取教训 +- 关注的不仅是个人，更是整个社区的最大利益 + +不可接受的行为包括但不限于： + +- 使用情色化的语言或意象，及任何形式的性关注或性骚扰 +- 嘲讽、侮辱或贬损性的评论，以及人身或政治攻击 +- 公开或私下的骚扰 +- 未经明确许可，公布他人的私人信息，例如物理或电子邮件地址 +- 其他在专业场合中可被合理认定为不当的行为 + +## 适用范围 + +本行为准则适用于所有社区场所，也适用于个人在公开场合代表社区时的言行。代表本社区的情形包括但不限于：使用项目官方电子邮件地址、通过项目官方社交媒体账号发文、以指定代表身份出席线上或线下活动。 + +具体到 SnowLuma，本准则适用于： + +- 本仓库（含 issue、PR、discussion、commit message、code review 评论） +- 项目相关的 QQ 群、Telegram 群以及未来可能新增的官方社群 +- 任何以 SnowLuma 名义对外发起的活动或交流 + +## 执行责任 + +社区维护者负责诠释并执行我们所认定的可接受行为标准，并将对任何他们认为不当、具威胁性、冒犯性或有害的行为采取适当且公正的纠正措施。 + +社区维护者有权且有责任删除、编辑或拒绝任何不符合本行为准则的评论、提交、代码、wiki 编辑、issue 及其他贡献，并将在适当时机说明做出审核决策的理由。 + +## 举报方式 + +如果你目击或亲身经历了不当行为，请通过以下任一渠道**私下**联系维护者： + +- QQ：[SnowLuma-QQ](https://qm.qq.com/q/g3UMLpWALe)（私聊管理员，请勿在群内公开） +- Telegram：[SnowLuma-TG](https://t.me/napcatqq)（私聊管理员） + +请勿在 GitHub issue 或公开频道直接发布举报内容，以免对相关方造成二次伤害。 + +所有投诉都会被及时和公平地审查与调查。所有社区维护者都有义务尊重举报者的隐私与人身安全。 + +## 执行准则 + +社区维护者将依据以下「社区影响指引」来判定违反本行为准则之行为的处置方式： + +### 1. 更正 (Correction) + +**社区影响**：使用了不恰当的言语，或其他在社区中被视为不专业或不受欢迎的行为。 + +**后果**：由社区维护者私下提出书面警告，明确指出该行为违反规则之处并解释为何不妥。可能要求公开致歉。 + +### 2. 警告 (Warning) + +**社区影响**：通过单一事件或一系列行为造成违规。 + +**后果**：警告并说明持续行为的后果。在指定时间内禁止与相关人员互动，包括主动联系本行为准则执行者。这包括避免在社区场所及外部渠道（如社交媒体）的互动。违反这些条款可能导致临时或永久封禁。 + +### 3. 临时封禁 (Temporary Ban) + +**社区影响**：严重违反社区准则，包括持续的不当行为。 + +**后果**：在指定时间内禁止与社区进行任何形式的互动或公开交流。在此期间不得与相关人员有任何公开或私下的互动，包括主动联系本行为准则执行者。违反这些条款可能导致永久封禁。 + +### 4. 永久封禁 (Permanent Ban) + +**社区影响**：表现出违反社区准则的模式，包括持续的不当行为、骚扰个人、或对某类群体进行攻击或贬低。 + +**后果**：永久禁止在社区内进行任何形式的公开互动。 + +## 致谢 + +本行为准则改编自 [Contributor Covenant 2.1 版](https://www.contributor-covenant.org/version/2/1/code_of_conduct.html)。 + +社区影响指引灵感来自 [Mozilla 的行为准则执行阶梯](https://github.com/mozilla/diversity)。 + +如需了解本准则的常见问题，请参阅 [FAQ](https://www.contributor-covenant.org/faq)。中文版译本可参考 [Contributor Covenant 中文翻译](https://www.contributor-covenant.org/zh-cn/version/2/1/code_of_conduct/)。 diff --git a/CONTRIBUTING.md b/CONTRIBUTING.md new file mode 100644 index 00000000..3633e63b --- /dev/null +++ b/CONTRIBUTING.md @@ -0,0 +1,342 @@ +# 贡献指南 + +欢迎！如果你正在阅读这份文档，多半是因为你想给 SnowLuma 提一个 PR、修一个 bug，或者只是想了解这个项目是怎么运作的。无论你是第一次接触开源、还是已经有十年经验，我们都希望让你尽快上手。 + +参与项目即视为你同意遵守 [行为准则（Code of Conduct）](./CODE_OF_CONDUCT.md)。在开始之前请花两分钟读一下，它定义了我们希望社区维持的氛围。 + +--- + +## 在动手之前 + +SnowLuma 处于开发早期，迭代速度很快，**接口与目录结构随时可能变化**。如果你打算做较大的改动，强烈建议先在 issue 或者社群里和维护者对齐一下方向，避免做了一半发现已经被另一条路替代。 + +提交 PR 前，必须先通过 [GitHub 网页模板](https://github.com/SnowLuma/SnowLuma/issues/new/choose) 提交对应 issue，或认领已有的对应 issue。可以只提 issue；提交 PR 是可选的后续步骤。 + +不知道从哪里入手？以下几类贡献最容易被合并： + +- 修复你在使用中遇到的具体 bug，附最小复现步骤。 +- 改善错误提示、文档、注释、类型签名。 +- 给已有模块补测试，尤其是 `packages/core` 下覆盖率较低的部分。 +- 实现 [RoadMap.md](./RoadMap.md) 中列出的、还没被认领的项。 + +如果你只是想看看代码长什么样，可以直接跳到 [本地开发环境](#本地开发环境)。 + +### AI Agent 贡献须知 + +如果你是 AI Agent，并准备为本仓库贡献代码、提交 PR 或提出 issue，请先明确告知你的使用者： + +> **请通过 GitHub 网页端手动使用模板创建 issue。未通过模板检查的 issue 会被自动关闭，也不能用于满足 PR 的关联要求。** + +你可以协助整理问题描述、复现步骤和相关日志，并将 issue 草稿交给用户，由用户在网页端完成提交。后续若创建 PR，必须先有符合要求的 issue，并在 PR 正文填写关联标记。 + +--- + +## 项目结构速览 + +这是一个 pnpm workspace monorepo，主要 package 如下： + +| 路径 | 作用 | +| --- | --- | +| `packages/core` | 应用入口、账号级 Bridge 编排、WebUI 服务端和发行构建 | +| `packages/bridge` | QQ 进程发现、Hook 会话和原生传输生命周期 | +| `packages/protocol` | QQ 数据包解码、身份解析、协议请求和媒体传输 | +| `packages/onebot` | OneBot 动作、事件转换、消息存储和传输适配 | +| `packages/common` | 日志、配置和共享工具 | +| `packages/proto-defs`、`packages/proton` | 协议结构定义、编译期 protobuf 编解码和构建集成 | +| `packages/sdk` | 面向第三方开发者的 SDK，会发布到 npm | +| `packages/mcp` | MCP 服务端和生成的动作目录 | +| `packages/ui` | 发布到 npm 的共享 UI 组件 | +| `packages/runtime` | 运行时辅助包 | +| `packages/websocket` | WebSocket 实现 | +| `packages/webui` | 基于 Vite + React 的前端控制台 | +| `tools/` | 版本管理、发布脚本 | +| `.github/workflows/` | CI / 发布 / Promote 工作流 | + +入口在 `packages/core/src/index.ts`，整体架构在 `packages/core/src/bridge/` 下能看出大致脉络。 + +--- + +## 本地开发环境 + +### 系统要求 + +- **Node.js 24.22.1（24 系列），或 26.12.1 及更新版本**；开发和构建使用 [`.node-version`](.node-version) 固定的版本。 +- **pnpm 11.25.0**（项目通过 `packageManager` 与 CI 统一版本） +- macOS / Linux / Windows 均可。如果要构建原生产物，需要对应平台的工具链。 + +如果系统提供 Corepack，可执行 `corepack enable pnpm`；没有 Corepack 时可执行 +`npm install -g pnpm@11.25.0`。进入仓库后，`node --version` 与 +`pnpm --version` 应满足上述版本要求，否则安装会直接失败。 + +### 拉代码、装依赖、跑起来 + +```bash +# 1.

It does not expand, replace, or imply any right not expressly granted by the `LICENSE`. +2.4 Proprietary Components (Section 5) are outside the scope of the source license and may be used only as permitted by Section 5 of the `LICENSE` and this Agreement. +2.5 The `LICENSE` controls the scope of rights in the source code and assets; this Agreement controls Proprietary Components in official distribution packages and matters specific to those binaries. A separate written commercial authorization controls only within the licensee, purpose, scope, quantity, and term that it expressly identifies. + +### 3. Disclaimers +3.1 **Not official; no affiliation.** The Software is an independent, third-party interoperability project and has **no affiliation, partnership, authorization, or endorsement relationship** with Tencent or QQ. "QQ", "Tencent", and related marks belong to their respective owners. +3.2 **Purpose.** Unless prior written commercial authorization has been obtained, the Software may be used only for **personal or other Non-Commercial purposes** permitted by the `LICENSE`, including study, research, technical interoperability, and Non-Commercial self-hosting. +3.3 **Compliance.** You are responsible for ensuring that your use complies with all applicable laws and with the terms of any platform you connect to (including the QQ User Agreement and related terms of service). +3.4 **AS-IS.** The Software is provided "**AS IS**" and "**AS AVAILABLE**", without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, non-infringement, availability, accuracy, or uninterrupted operation. +3.5 **Limitation of liability.** To the maximum extent permitted by law, SnowLumaDevs shall **not be liable** for any direct, indirect, incidental, special, punitive, or consequential damages (including account suspension or restriction, data loss, lost profits or business, or service interruption) arising from use of or inability to use the Software. +3.6 **Assumption of risk.** You understand that using an unofficial protocol tool to connect to a third-party platform **may violate that platform's terms and carry account risk**, which you **voluntarily assume**. + +### 4.

Termination of any separate written commercial authorization, and the parties' post-termination rights and obligations, are governed by that authorization's express terms. + +### 7. Governing Law and Disputes +This Agreement is governed by the laws of the **mainland of the People's Republic of China** (excluding its conflict-of-laws rules). Any dispute arising out of or relating to this Agreement shall first be resolved through good-faith negotiation; failing that, either party may bring an action before a **court of competent jurisdiction**. + +### 8.

Overview +SnowLuma is **self-hosted**: it runs on **your own device or server**. **By default, SnowLumaDevs (the authors) collect, receive, and store none of your data.** The Software contains **no** activation that requires network access or transmits information back to the authors. The only data that ever leaves your device is described in Sections 4 and 5, and telemetry is strictly limited (Section 5). + +### 2. Data the Software Stores on Your Device +To function, the Software stores the following categories of data locally (e.g., in a SQLite database, configuration, and log files). **This data stays on your device under your control; the authors cannot access it:** +- **Account & credentials:** the signed-in QQ account, session/tokens, and the WebUI login password (stored as a **salted scrypt hash**, never in plaintext). +- **Relationship data:** lists and profiles of friends, groups, and members. +- **Message data:** messages processed or cached for protocol conversion (depending on your configuration). +- **Runtime configuration & logs.** + +> Note: Because SnowLuma is a QQ protocol tool, this local data **necessarily** includes QQ account and contact information. This does not conflict with Section 5 ("telemetry never collects QQ account/contacts") — local storage ≠ outbound transmission. + +### 3. You Are the Data Controller +When you run the Software to process the personal information of your QQ contacts, group members, or other individuals, **you are the data controller/processor** for that information and are responsible for compliance (obtaining any necessary consent, securing the data, responding to data-subject requests). The authors merely provide a software tool and take no part in your processing. + +### 4. The Only Ways Data Leaves Your Device +The Software transmits your data to an external destination only in these two cases: +1. **Notifications / webhooks you configure:** when you set up a notification channel (e.g., a webhook), the relevant content is sent to **the address and settings you provide**. You fully control the destination and content; the authors are not involved. +2. **Anonymous telemetry:** see Section 5. + +### 5. Telemetry +**Mode: ON by default (opt-out).** You can disable it at any time (see 5.3). + +#### 5.1 What is collected (anonymous, aggregate, non-identifying only) +- Application version, OS and CPU architecture, Node.js version; +- Launch counts and feature-usage counts (e.g., which adapters/commands are enabled — **never their arguments or content**); +- Anonymized crash stacks and error types. + +#### 5.2 Never collected (explicit negative list) +Telemetry will **never, under any circumstances**, collect or transmit: +- **QQ account / UIN, or the identity of any friend, group, or member**; +- **Message content or metadata**, nicknames, avatars; +- Phone numbers, emails, or any contact details; +- Credentials, tokens, passwords; +- Precise IP addresses used for profiling (any IP incidentally visible at the transport layer is discarded immediately, not stored, not correlated); +- Any identifier that could directly or indirectly identify a natural person. + +#### 5.3 How to disable; notice +- **First-run notice:** on first run the Software gives a one-time notice in the console and WebUI that telemetry is on by default and how to disable it. +- **One switch off:** disable any time via the `SNOWLUMA_TELEMETRY=0` environment variable, a config option, or the WebUI toggle; collection stops immediately. + +#### 5.4 Use, sharing, retention +Telemetry is used **only to improve the Software**, is **never sold or shared with any third party**, and is retained only in anonymous aggregate form for as long as necessary. + +#### 5.5 Effective status (important) +This Section fully describes SnowLuma's telemetry mechanism but is **effective only for builds that actually contain telemetry code.** +> **Current status (as of 2026-06-17):** public releases **do not yet contain** telemetry code, so this Section is currently **not in effect**. If a release introduces telemetry, its release notes will say so and this Section will take effect for that release. + +### 6. Security & Retention +Security and retention of local data are under your (the operator's) control. Protect device access and rotate the WebUI password regularly. + +### 7. Third-Party Components +The Software may bundle third-party components (such as FFmpeg for media processing). These run **locally** on your device to process local data and **send nothing** to the authors or third parties. + +### 8. Minors +The Software targets developers and technical users, is **not directed to minors**, and the authors do not knowingly collect minors' information. + +### 9. Your Rights +Because the authors hold none of your personal data by default, rights of access, correction, and deletion are exercised by you **over the data on your own device**. If telemetry is enabled and you have questions, contact us (Section 10). + +### 10. Contact +Privacy inquiries: **motricseven@foxmail.com**. + +### 11. Changes +This Notice may be updated from time to time; updated versions bear an effective date. Material changes affecting telemetry will be prominently noted in release notes. diff --git a/README.md b/README.md new file mode 100644 index 00000000..3a8e7979 --- /dev/null +++ b/README.md @@ -0,0 +1,110 @@ +# SnowLuma + +**让 QQ 原生会话，连接你的应用。** + +QQ 客户端的 TypeScript 互操作运行时。

+// @snowluma/mcp — an MCP server for the SnowLuma OneBot action catalog.
+//
+// Two modes in one binary:
+//   • docs  (default, no endpoint): read-only catalog tools (list/get/search/
+//     categories) + a catalog resource. Zero contact with any live instance.
+//   • read / write (when SNOWLUMA_MCP_ENDPOINT is set): the catalog tools PLUS
+//     execution — query_action (read-only actions) and, in write mode,
+//     invoke_action (any known action) — proxied to a running OneBot instance
+//     over HTTP.
+//
+// Env:
+//   SNOWLUMA_MCP_ENDPOINT    OneBot HTTP endpoint (e.g. http://127.0.0.1:3000/).
+//                            Absent → docs-only (execution tools hidden).
+//   SNOWLUMA_MCP_TOKEN       access token (Bearer) for the endpoint.
+//   SNOWLUMA_MCP_TIMEOUT_MS  ordinary request timeout; Stream connection and
+//                            per-read idle timeout (default 30s).
+//   SNOWLUMA_MCP_MODE        docs | read | write. Default: read when an
+//                            endpoint is set, else docs.
+//   SNOWLUMA_MCP_STREAM_DIR  MCP-host directory for completed downloads.
+//   SNOWLUMA_MCP_UPLOAD_ROOT Existing MCP-host directory allowed for uploads.
+//   SNOWLUMA_MCP_MAX_STREAM_BYTES  Per-file cap (1..4 GiB; default 4 GiB).
+//   SNOWLUMA_MCP_TASK_DIR    Private persistent task directory (write mode only).
+//   SNOWLUMA_MCP_EVENTS_URL Explicit OneBot event WebSocket endpoint.
+//
+// NOTE: stdout is the MCP protocol channel — all diagnostics go to stderr.

+# @snowluma/proton
+
+Compile-time protobuf codecs for SnowLuma. TypeScript schemas and generic calls
+are compiled into specialized encoders and decoders without runtime schema lookup.
+
+Vendored from [SnowLuma/protobuf-dsl](https://github.com/SnowLuma/protobuf-dsl)
+(`protobuf-fastdsl`, commit `22e382a`), whose README declares the MIT license.
+SnowLuma retains the `@snowluma/proton` package name, manifest and wire compatibility
+rules described below.
+
+## Setup
+
+Add `@snowluma/proton: workspace:*` to the consuming package's dependencies and
+enable the plugin in its Vite or Vitest configuration:
+
+```ts
+import { defineConfig } from 'vite';
+import protobufVitePlugin from '@snowluma/proton/vite';
+
+export default defineConfig({
+    plugins: [protobufVitePlugin()],
+});
+```
+
+The plugin entry resolves to a built artifact. After editing the compiler, run
+`pnpm --filter @snowluma/proton build` before testing consuming packages.
+Calls without the plugin throw a diagnostic naming `@snowluma/proton/vite`.
+
+```ts
+import type { pb, pb_optional, pb_repeated, uint_32 } from '@snowluma/proton';
+import { protobuf_encode, protobuf_decode } from '@snowluma/proton';
+
+interface Profile {
+    id?: pb<1, uint_32>;
+    name?: pb<2, string>;
+    tags?: pb_repeated<3, string>;
+    state?: pb_optional<4, uint_32>;
+}
+
+const bytes = protobuf_encode({ id: 42, name: 'alice', state: 0 });
+const profile = protobuf_decode(bytes);
+```
+
+## Schema and compiler support
+
+`pb` marks a singular field, `pb_repeated` marks a repeated field,
+and `pb_optional` gives a singular field explicit wire presence.
+
+| Types | TypeScript value | Wire format |
+| --- | --- | --- |
+| `uint_32`, `int_32`, `sint_32` | `number` | Varint; `sint_32` uses zigzag |
+| `uint_64`, `int_64`, `sint_64` | `bigint` | Varint; `sint_64` uses zigzag |
+| `bool` | `boolean` | Varint |
+| `fixed_32`, `sfixed_32`, `float` | `number` | 32-bit |
+| `fixed_64`, `sfixed_64` | `bigint` | 64-bit |
+| `double` | `number` | 64-bit |
+| `string`, `bytes` | `string`, `Uint8Array` | Length-delimited |
+| Message interfaces | Object | Length-delimited |
+
+The compiler resolves aliases, namespace imports, `export *`, relative and bare
+package imports, nested generic schemas, generic functions and classes, and
+forwarded callbacks. It preserves wrapper bodies and passes generated codecs
+through generic calls. It also supports resolvable mapped, conditional and utility
+types; ambiguous unions and unresolved schemas fail during compilation.
+
+Only required codecs and helpers are emitted. Nested message encoders measure and
+write into a shared output buffer. Returned bytes may be a view into a larger
+buffer; use `byteOffset` and `byteLength`, or `bytes.slice()` when an independent
+backing buffer is needed. Later encodes do not overwrite previously returned bytes.
+
+## SnowLuma wire compatibility
+
+- Plain `pb<>` scalars omit default values (`0`, `0n`, `false`, empty strings and
+  empty bytes), including fields marked with TypeScript `?`. Missing optional
+  singular fields decode to `null`.
+- `pb_optional<>` emits present default values while omitting `null`/`undefined`.
+  This preserves the explicit `state=0` needed to disable whole-group mute.
+- Negative `int_32` values retain SnowLuma's five-byte outbound encoding. Decoders
+  accept both that form and canonical ten-byte sign-extended values.
+- `uint_32` values consume a complete valid varint of up to ten bytes and retain
+  the low 32 bits. Tags and lengths remain limited to valid 32-bit framing.
+- Decoders reject truncated/overflowing fields, invalid bounds and malformed
+  groups. Unknown groups are skipped within their parent frame with bounded depth.
+- Unknown tags retain non-enumerable metadata, available through
+  `protobuf_getUnknownFields` and `protobuf_getUnknownFieldMetadata`. Metadata
+  aggregates occurrences, retains at most 64 field/wire kinds per message, and
+  summarizes omitted kinds without retaining their payloads.
+
+The previous runtime-map fallback and plugin option have been removed. Consumers
+must compile encode/decode calls with the plugin.
+
+## Migration audit
+
+The upstream implementation was checked against Proton's source history before
+replacement. The following behavior is covered by regression tests:
+
+| Proton history | Upstream status / retained behavior |
+| --- | --- |
+| Initial vendor fixes (`194165f4`) and generic OIDB migration (`58028123`) | Aliased markers, nested generic fields and forwarded wrappers are covered by the new compiler and integration tests. |
+| Barrel exports (`f21740a5`) and bare imports (`994633ea`) | Supported by the new source resolver; tested through bundled cross-file and package fixtures. |
+| Explicit presence (`90f26ca4`) | Added `pb_optional` to the new schema pipeline and kept `?` separate from wire presence. |
+| Decoder hardening (`b7d648ea`) | Upstream already checks varints and field boundaries; retained integer bounds, group handling, bounded unknown metadata and legacy outbound `int32` bytes. |
+| Extended `uint32` (`b53004ee`, `613b2b1e`) | Upstream consumes full value varints; retained the existing QQ regression fixtures. |
+| Cleanup (`c7428363`) | Superseded by the new compiler/source module structure. |
+
+## Validation and layout
+
+From the repository root:
+
+```sh
+pnpm --filter @snowluma/proton build
+pnpm --filter @snowluma/proton typecheck
+pnpm --filter @snowluma/proton test
+```
+
+`test/upstream` contains the imported compiler, codegen and plugin suite, adjusted
+for SnowLuma's package layout and wire rules. `test/__tests__` retains Proton's
+wire regression tests and adds migration compatibility cases. Consumer tests in
+`packages/protocol/tests` exercise real QQ schemas with the built plugin.

+# Changelog
+
+## Unreleased
+
+- Fix ordinary WebSocket request deadlines to include connection waits, prevent expired requests from being sent after a late open, and preserve shared connections when an individual request times out or is cancelled. Refs #666.
+
+- Add typed public contact profiles and opt-in friend-list enrichment via `getFriendList({ withProfile: true })` or `with_profile` on either list action; existing request options remain compatible. See [contact profiles](../onebot/CONTACT_PROFILES.md).
+
+- Add a Node reverse WebSocket server with authenticated per-account sessions, Universal and paired API/Event channels, existing action/event/stream helpers, bounded buffers and explicit disconnect handling; see [REVERSE_WEBSOCKET.md](REVERSE_WEBSOCKET.md).
+
+- Add one-step local media sends, the optional `@snowluma/sdk/node` file source, stage-aware errors, explicit quoted replies, and cancellable WebSocket event waits; see [MESSAGING.md](MESSAGING.md). Existing methods and handler/context types remain compatible.
+- Report group-file chat publication failures through the runtime's existing error response instead of returning a successful upload result after publication fails.
+- Add HTTP and WebSocket `requestStream()` / `stream()`, incremental `uploadFileStream()` / `downloadFileStream()` helpers, cancellation, bounded response buffering, and transfer validation. Existing single-response methods remain unchanged; see [STREAMING.md](STREAMING.md).
+- Add parameter and result types for the remaining 57 actions and three aliases, covering every registered action name while preserving existing client methods and type mappings.
+- Describe album pagination and media, Qzone, flash transfers, stickers, group settings, and stream frame payloads; retain numeric-string inputs and signed message IDs.
+- Fix native Node.js ESM imports for the package root and all supported subpaths without requiring a bundler.
+- Restore `@snowluma/sdk/actions` and the root exports `SNOWLUMA_ACTIONS`, `isSnowLumaAction`, and `SnowLumaKnownAction`, including current action names and compatibility aliases.
+- Require patched Node.js releases: 24.22.1 or newer in the 24.x line, or 26.12.1 and newer.
+
+## 2.0.0
+
+Upgrade to Node.js 24 or newer before updating the SDK. SDK and application versions are released together.
+
+- Add typed `get_qzone_msg_detail` support for reading a post and its comment page with inline replies.
+- Release cancellation listeners as soon as a request stops waiting for a connection.
+- Isolate WebSocket connection lifetimes and release request timers and abort listeners on every outcome.
+- Reject duplicate in-flight WebSocket echoes instead of overwriting the original request.
+- Add `getGroupShareLink()` and typed `get_group_share_link` support for group invitation links.
+- Breaking: require Node.js 24 or newer.
+- Add `CustomReplySegment` and `message.customReply()` for inline quote previews inside merged-forward nodes.
+- Expose optional inline content and quote metadata on received `ReplySegment` values.
+- Reject CQ serialization of nested custom-reply content instead of silently stringifying message objects.
+- Preserve string custom-reply content and metadata when parsing CQ strings.
+- Decode CQ parameters once so literal entity text such as `,` survives round trips.
+
+## 0.1.0
+
+- Initial SnowLuma TypeScript SDK package.
+- Added HTTP and WebSocket clients for OneBot APIs.
+- Added event middleware, command matching, request context helpers, and message chain builders.
+- Added structured SDK error classes and per-request `AbortSignal` support.

+# Media sends, quoted replies, and event waits
+
+These helpers are additive. Existing string media paths still refer to the SnowLuma server, `context.reply()` still sends an ordinary reply, and existing event subscriptions and middleware keep their behavior.
+
+## Send local media
+
+Both HTTP and WebSocket clients provide `sendGroupImage`, `sendPrivateImage`, `sendGroupRecord`, `sendPrivateRecord`, `sendGroupVideo`, `sendPrivateVideo`, `sendGroupFile`, and `sendPrivateFile`.
+
+```ts
+import { SnowLumaHttpClient } from '@snowluma/sdk';
+import { localFile } from '@snowluma/sdk/node';
+
+const bot = new SnowLumaHttpClient({ baseUrl: 'http://127.0.0.1:3000/' });
+const receipt = await bot.sendGroupImage(12345, await localFile('./picture.png'), {
+    image: { summary: 'Picture' },
+    onProgress: ({ uploadedBytes, fileSize }) => {
+        console.log(`${uploadedBytes}/${fileSize} bytes uploaded`);
+    },
+});
+console.log(receipt.message_id);
+
+await bot.sendPrivateFile(67890, await localFile('./report.pdf'), { name: 'Report.pdf' });
+```
+
+Sources may be `Uint8Array` (including Node `Buffer`), `Blob` / browser `File`, `ReadableStream`, or `AsyncIterable` (including a byte-mode Node readable). Streams and async iterables require `fileSize`. A `{ source, filename }` wrapper supplies a name without changing the byte source. Browser `File` names are inferred; an explicit `filename` option overrides them.
+
+`localFile(pathOrFileURL)` is available **only** from `@snowluma/sdk/node`. It returns a named, file-backed Blob without reading the entire file into memory. The file must remain unchanged until sending finishes; missing, non-regular, or changed files produce errors. The root and browser-facing entry points do not import Node filesystem modules. A browser can pass a selected `File` directly.
+
+The helpers await every chunk acknowledgement and upload completion, then use the returned **server path** in the final action. Image, record, and video methods return the ordinary `{ message_id }` result. File methods call the existing file publishing actions and return `{ file_id }`. `sendGroupFile` accepts `folder` / `folderId`; file methods accept a display `name`, defaulting to the uploaded name. Media attributes go under `image`, `record`, or `video`. A `video.thumb` path still refers to the server and is not uploaded automatically.
+
+All [upload options](STREAMING.md) apply, including `chunkSize`, `expectedSha256`, `fileRetention`, `signal`, and `onProgress`. Progress measures acknowledged uploaded bytes, not message delivery. `timeoutMs` is a timeout **per upload request and final send request**, not a deadline for the entire operation or source reads. Use an `AbortSignal` with your own deadline for an overall cancellation policy.
+
+```ts
+import { SnowLumaMediaSendError } from '@snowluma/sdk';
+
+try {
+    await bot.sendPrivateImage(67890, new Uint8Array([/* image bytes */]), {
+        signal: AbortSignal.timeout(60_000),
+    });
+} catch (error) {
+    if (error instanceof SnowLumaMediaSendError) {
+        console.error(error.stage, error.cause);
+        // error.upload contains completion metadata if uploading finished.
+    }
+    throw error;
+}
+```
+
+Errors carry `stage: 'upload' | 'send'`, the original `cause` (including API, abort, and timeout errors), and completed upload metadata when available. Cancellation between stages prevents sending. Cancellation or timeout after dispatch does not prove that the server failed to send: there is no automatic retry, rollback, or remote deletion. Remote retention and partial-upload expiry remain controlled by the existing upload service. The accompanying runtime fix reports a failed group-file chat publication as an error, retaining the uploaded file ID in the error context; it no longer returns success after that failure.
+
+## Quote a message explicitly
+
+```ts
+import { SnowLumaWebSocketClient, quoteMessage, text } from '@snowluma/sdk';
+
+const bot = new SnowLumaWebSocketClient();
+bot.onGroupMessage(async (event, context) => {
+    if (event.post_type === 'message' && event.raw_message === '/ping') {
+        await context.quote(text('pong'));
+    }
+});
+await bot.connect();
+
+// HTTP clients or code outside an event handler can compose the same quote.
+await bot.sendGroupMessage(12345, quoteMessage(-42, 'Reply body'));
+```
+
+`context.quote()` routes to the event's group or private conversation and uses its message ID. It rejects non-message events. IDs are non-zero signed 32-bit integers; negative IDs are preserved. `quoteMessage(id, body, options?)` is also exported from `@snowluma/sdk/messages` and only composes content, without making a request.
+
+Bodies accept strings, CQ strings, a segment, arrays of segments, and message chains. String CQ content retains its original fields and escaping. With `autoEscape: true`, a string becomes literal text following the quote; arrays and chains remain structured. A body that already contains a reply segment is rejected, and inputs are not mutated. This does not fetch the referenced message; the server must be able to resolve its ID.
+
+Old `SnowLumaEventContext` objects and explicitly typed handlers remain valid. SDK-created contexts and inferred client callbacks expose `SnowLumaEventContextWithQuote`. To annotate a reusable new handler, use `EventHandler>` (or the corresponding context parameter of `EventMiddleware` / `CommandHandler`).
+
+## Wait for a future event
+
+Private messages marked by QQ as automatic replies carry `auto_reply: true` in live events and friend history. Check `event.auto_reply === true` to filter them. SnowLuma preserves the reply text, including any literal `[自动回复]` the sender typed. Older locally stored messages may lack the flag.
+
+`waitForEvent(predicate?, options?)` and `waitForMessage(predicate?, options?)` are available on the WebSocket client. Both also accept just the options object. Synchronous type-guard predicates narrow the resolved type; boolean predicates filter without claiming a narrower type.
+
+```ts
+const controller = new AbortController();
+await bot.connect();
+try {
+    // Register before sending so a fast reply cannot arrive before the listener.
+    const reply = bot.waitForMessage(
+        (event) => event.post_type === 'message'
+            && event.message_type === 'private'
+            && event.user_id === 67890,
+        { timeoutMs: 30_000, signal: controller.signal },
+    );
+    const [incoming] = await Promise.all([
+        reply,
+        bot.sendPrivateMessage(67890, 'Ready?', { signal: controller.signal }),
+    ]);
+    console.log(incoming.raw_message);
+} finally {
+    controller.abort(); // Also releases the wait if sending failed first.
+}
+```
+
+Waits register synchronously and do not connect, replay history, consume events from other listeners, or persist across reconnects. They observe the same public event stream as `onEvent`, **after middleware**; events stopped by middleware are not visible. `waitForMessage` includes both `message` and `message_sent`, so filter direction, conversation, and sender when needed. Multiple waits can resolve from the same event.
+
+The default timeout is the client's `requestTimeoutMs` (30 seconds by default); `0` disables it. Timeout rejects with `SnowLumaTimeoutError`, cancellation with `SnowLumaAbortError`, and disconnect or explicit `close()` with `SnowLumaConnectionError`. Predicate exceptions reject with their original error. Every completion path removes its listener, abort handler, and timer. Cancellation affects the wait only; it does not close the client or undo a sent message.
+
+## Reply to a Qzone comment
+
+Both clients expose this through the typed `raw('comment_qzone', params)` action. Omitting `comment_id` and `comment_uin` preserves ordinary comments, including image uploads. `target_uin` always identifies the **post owner**, not the person being replied to.
+
+Read `get_qzone_msg_detail` to obtain a parent comment's `comment_id` and `uin`. Pass both to create a text reply under that comment; `"0"` is a valid comment ID. To address someone inside the thread, also pass their `uin` and `name` as `reply_uin` and `reply_name`:
+
+```ts
+const result = await bot.raw('comment_qzone', {
+  tid: post.tid,
+  target_uin: postOwnerUin,
+  comment_id: parentComment.comment_id,
+  comment_uin: parentComment.uin,
+  reply_uin: selectedReply.uin,
+  reply_name: selectedReply.name,
+  content: 'Thanks for the explanation!',
+});
+console.log(result.comment_id, result.parent_comment_id);
+```
+
+`post`, `postOwnerUin`, `parentComment` and `selectedReply` above are the post and comments chosen by the caller. For an ordinary reply to the parent, omit `reply_uin` and `reply_name`. For a nested reply, keep the **top-level parent** in `comment_id`/`comment_uin`; do not substitute the nested reply's own ID. New servers also include `parent_comment_id` and `parent_comment_uin` on each inline reply to preserve this association. Inline replies may be incomplete; absence from a page does not mean a comment was deleted.
+
+On success, `comment_id` is the **new reply's** ID and the result includes its parent ID and author. Those parent fields are optional in SDK types for compatibility with older servers. Non-empty `images` with a parent comment are rejected before upload: threaded replies currently support text only. Incomplete recipient/parent parameters are errors, and a failed reply never falls back to an ordinary comment or retries automatically. If an acknowledgement is malformed after sending, check the thread before retrying; the reply may already exist.
+
+## Read structured Qzone friend feeds
+
+`get_qzone_feeds` retains `page_num`, `count`, `feeds`, `has_more`, and each feed's
+original `html`. Newer servers also return `tid`, `content`, `content_complete`,
+`images`, `like_count`, and `comment_count`. A `null` value means the source did
+not establish that field; it does not mean zero or an empty post. A collapsed
+excerpt has `content_complete: false`. Images cover only pictures available in
+the post body, excluding avatars, comment pictures and video covers; they are
+not a complete album listing. Non-post feed types may have no `tid`.
+
+Use the returned `next_cursor` unchanged to continue on the same account:
+
+```ts
+let cursor: string | undefined;
+while (true) {
+    const page = await bot.raw('get_qzone_feeds', { count: 10, cursor });
+    for (const feed of page.feeds) {
+        console.log(feed.content, feed.images);
+    }
+    if (!page.has_more) {
+        break;
+    }
+    if (!page.next_cursor) {
+        throw new Error('This server did not provide a continuation cursor');
+    }
+    cursor = page.next_cursor;
+}
+```
+
+Omit `page_num` when using a cursor, or supply its corresponding page number.
+Without a cursor, requesting a later `page_num` walks earlier pages from the
+beginning and can take longer; requesting beyond the end returns an empty page.
+The service may return fewer entries than `count`, including empty intermediate
+pages with a continuation. Follow `has_more` and `next_cursor`, not array length.
+Invalid, foreign-account or stalled cursors fail visibly. Results reflect a live
+feed, not a frozen snapshot; posts may change between requests.
+
+The added result fields are optional in SDK types so older servers and existing
+consumer-created result objects remain supported. MCP discovers the same fields
+and cursor examples through `get_action` and calls this read-only action through
+`query_action`; its existing mode restrictions are unchanged.

+
+## 安装
+
+在本 monorepo 内直接通过 workspace 引用：
+
+```bash
+pnpm add @snowluma/sdk --workspace
+```
+
+发布到 npm 后可直接安装：
+
+```bash
+pnpm add @snowluma/sdk
+```
+
+## 快速开始
+
+```ts
+import { SnowLumaHttpClient, text } from '@snowluma/sdk';
+
+const bot = new SnowLumaHttpClient({
+  baseUrl: 'http://127.0.0.1:3000/',
+  accessToken: process.env.SNOWLUMA_TOKEN,
+});
+
+const login = await bot.getLoginInfo();
+await bot.sendGroupMessage(123456, text(`Hello from ${login.nickname}`).at('all'));
+```
+
+SnowLuma 的 OneBot HTTP / WebSocket 端口和 `accessToken` 来自 `config/onebot_.json`。
+
+## HTTP Client
+
+```ts
+import { SnowLumaHttpClient, message, text } from '@snowluma/sdk';
+
+const bot = new SnowLumaHttpClient({
+  baseUrl: 'http://127.0.0.1:3000/',
+  accessToken: process.env.SNOWLUMA_TOKEN,
+  requestTimeoutMs: 30_000,
+});
+
+await bot.sendPrivateMessage(10001, text('pong'));
+
+const { url } = await bot.getGroupShareLink(123456);
+
+await bot.sendGroupMessage(123456, [
+  message.text('Hello'),
+  message.at('all'),
+]);
+```
+
+## WebSocket Client
+
+WebSocket 客户端会用 `echo` 关联 API 响应，并把无 `echo` 的包作为事件分发。
+
+```ts
+import { SnowLumaWebSocketClient, text } from '@snowluma/sdk';
+
+const bot = new SnowLumaWebSocketClient({
+  url: 'ws://127.0.0.1:3001/',
+  accessToken: process.env.SNOWLUMA_TOKEN,
+  reconnect: true,
+});
+
+bot.onGroupMessage(async (event, ctx) => {
+  if (event.raw_message === '/ping') {
+    await ctx.reply(text('pong').at(event.user_id));
+  }
+});
+
+bot.onRequest('friend', async (_event, ctx) => {
+  await ctx.approve();
+});
+
+bot.onBotStatus((event) => {
+  console.log(event.sub_type, event.user_id);
+});
+
+await bot.connect();
+await bot.sendPrivateMessage(10001, text('ready'));
+```
+
+## 事件中间件与命令
+
+```ts
+bot.use(async (event, ctx, next) => {
+  console.log(event.post_type);
+  await next();
+});
+
+bot.command('echo', async (_event, ctx, match) => {
+  await ctx.reply(text(match.rest || 'empty'));
+});
+
+bot.when(
+  (event) => event.post_type === 'notice',
+  async (event) => console.log(event),
+);
+```
+
+事件上下文内置快捷操作：
+
+- `ctx.reply(message)`：按私聊/群聊自动回复。
+- `ctx.approve()` / `ctx.reject(reason)`：处理好友或群请求。
+- `ctx.quickOperation(operation)`：调用 `.handle_quick_operation`。
+- `ctx.stopPropagation()`：停止后续中间件和普通 `onEvent` 分发。
+
+## Raw Action
+
+动画系统表情可通过 `face(id, { resultId: '0' })` 指定结果，收到的结果保留在 `face.data.resultId` 中。不传时沿用默认选择；有效结果取决于具体表情，不能与 `large: false` 同用。
+
+`await bot.getStatus()` 的 `time` 为当前账号服务实例的运行秒数，与 `#sl` 使用相同计时起点；实例重建后重新计时。
+
+高频接口提供 camelCase 方法；其它 SnowLuma action 可以用 `raw` 或 `rawResponse`：
+
+```ts
+const data = await bot.raw('get_group_file_system_info', {
+  group_id: 123456,
+});
+
+const response = await bot.rawResponse('get_status');
+```
+
+`raw` 会在 SnowLuma 返回 `status: "failed"` 或非零 `retcode` 时抛出 `SnowLumaApiError`；`rawResponse` 会保留完整响应。
+
+### 读取与修改空间资料
+
+`get_qzone_profile` 返回 QQ 空间的名称和说明；这两个字段独立于 QQ 昵称和个性签名。
+
+```ts
+const profile = await bot.raw('get_qzone_profile', {}); // 当前账号
+console.log(profile.name, profile.description);
+await bot.raw('get_qzone_profile', { target_uin: '10002' });
+
+await bot.raw('set_qzone_profile', { name: '我的空间' });
+await bot.raw('set_qzone_profile', { description: '' }); // 清空说明
+```
+
+`set_qzone_profile` 只修改当前账号，至少提供 `name`、`description` 中的一项；省略字段保持原值，空字符串表示清空。成功返回 `null`，登录失效、访问受限或上游要求验证时会抛出 `SnowLumaApiError`。修改后可再次读取资料确认结果。
+
+### 读取空间说说评论
+
+`get_qzone_msg_detail` 是只读扩展动作，`raw` 提供参数和结果类型：
+
+```ts
+const detail = await bot.raw('get_qzone_msg_detail', {
+  tid: '说说 ID', // 来自 get_qzone_msg_list / send_qzone_msg
+  // target_uin: 10001, // 省略时读取机器人自己的空间
+  pos: 0,
+  num: 20,
+});
+
+for (const comment of detail.comments) {
+  console.log(comment.comment_id, comment.uin, comment.name, comment.time, comment.content);
+  console.log(comment.replies); // 服务端内联返回的二级回复
+}
+```
+
+`comment_num` 是服务端报告的总数，`comments` 是本页一级评论；`num` 范围为 1–100，实际返回数量可能更少。二级回复不单独分页，`replies` 不保证完整。评论 ID 在所属说说内唯一，二级回复 ID 在父评论内唯一；时间均为 Unix 秒，正文保留空间表情和 @ 标记。该接口复用当前账号的空间登录态，登录或访问权限失败会抛出 `SnowLumaApiError`。
+
+分页参数及 `commentlist` / `list_3` 字段参考 [Qzone-API](https://github.com/SmartHypercube/Qzone-API/blob/master/qzone.py)。实际分页和可见内容取决于 QQ 空间服务端。
+
+### 空友爱看与公共空间
+
+`get_qzone_home_feeds` 读取自己的空间主页，可传 `target_uin` 访问有权限的其他主页；`cursor` 使用同一账号、同一主页上次返回的 `next_cursor`。它返回完整动态，旧版 `get_qzone_feeds` 和 `get_qzone_msg_list` 保持原有格式。
+
+已有说说编号时，可调用 `get_qzone_feed_detail`，传入 `get_qzone_msg_list` 或 `send_qzone_msg` 返回的 24 位十六进制 `tid`。此接口读取普通空间说说，自动从编号取得作者和发布时间，不需要 `target_uin`；访问仍使用当前账号的权限。结果的 `feed` 是单个完整动态对象，保留图片、视频、分享信息和未知字段，无需再取 `.feed.feed`。其余上游详情字段也会保留，`attach_info` 为上游评论游标（未提供时为 `null`）；只读取一次详情，不自动翻页，也不保证评论和回复完整。旧的 `get_qzone_msg_detail` 及其 `pos/num` 分页保持不变。
+
+```ts
+const detail = await bot.raw('get_qzone_feed_detail', {
+  tid: '1127000000f1536501000000', // 替换为实际说说编号
+});
+const card = await bot.raw('get_qzone_share_ark', { feed: detail.feed });
+// 若 card.requires_confirmation 为 true，发送前展示 card.notice 并取得确认。
+```
+
+把详情、主页或推荐列表的完整动态传给 `get_qzone_share_ark`，可获得 `{ ark, requires_confirmation, notice }`。此动作会生成分享卡片但不发送消息；将 `ark` 原文交给普通 JSON 消息发送接口即可获得消息编号，继续使用已有撤回及发送事件能力。能读取不代表允许分享：分享受限或缺少上游分享信息时，分享接口会明确报错。
+
+分享链接可能让未登录者也能访问动态，并包含作者 QQ 号。若 `requires_confirmation` 为 `true`，发送前应展示 `notice` 并取得确认；上游禁止分享或生成失败会返回错误。
+
+```ts
+const page = await bot.raw('get_qzone_home_feeds', {});
+if (page.feeds[0]) {
+  const card = await bot.raw('get_qzone_share_ark', { feed: page.feeds[0] });
+  // 先按 requires_confirmation / notice 确认分享范围，再由调用方决定是否发送。
+  // 发送时使用 [{ type: 'json', data: { data: card.ark } }]，保持卡片原文。
+}
+```
+
+公共空间动作使用推荐域 `3` 的 JSON 接口，与上面的旧空间 CGI 动作分开。先读取 `get_qzone_public_feeds`，再把返回的完整 `feed` 对象传给详情和互动动作，保留其中的身份、传递数据及未知字段；不要用旧说说 `tid` 拼造。
+
+| 动作 | 主要参数 |
+| --- | --- |
+| `get_qzone_public_capabilities` | 无；读取当前账号的入口能力 |
+| `get_qzone_public_feeds` | 可选 `cursor` |
+| `get_qzone_public_feed_detail` | `feed` |
+| `get_qzone_public_comments` | `feed`、`cursor` |
+| `get_qzone_public_replies` | `feed`、完整 `comment`，可选 `cursor`、`page_size`（默认 20） |
+| `set_qzone_public_upvote` / `set_qzone_public_like` / `set_qzone_public_follow` | `feed`，可选 `enable`（默认 `true`，`false` 取消） |
+| `set_qzone_public_comment_like` | `feed`、完整 `comment`，可选完整 `reply`、`enable`（默认 `true`） |
+| `comment_qzone_public_feed` | `feed`、`content` |
+| `reply_qzone_public_feed` | `feed`、完整 `comment`、`content`，可选完整 `reply` |
+| `delete_qzone_public_comment` / `delete_qzone_public_reply` | `feed`、完整 `comment`；删除回复还需完整 `reply` |
+| `forward_qzone_public_feed` | `feed`，可选 `reason`（默认空字符串） |
+
+“推”与“赞”是不同的互动，分别使用 `set_qzone_public_upvote` 和 `set_qzone_public_like`。评论或回复的 `content` 接受非空文本或非空的上游富文本对象数组。详情、评论、回复及写操作保留上游结果字段，`raw` 返回这些 JSON 对象；列表的 `feeds` 已去掉上游每项的 `.feed` 包装，其余字段保持开放。
+
+QQ 上游会对评论换行做归一化，返回的富文本保持上游格式。
+
+`set_qzone_public_comment_like` 为评论点赞；提供 `reply` 时改为给该回复点赞，`enable: false` 取消。保留评论或回复自带的 `like.id`，不要将它替换成评论 ID。
+
+```ts
+const page = await bot.raw('get_qzone_public_feeds', {});
+if (page.has_more && page.next_cursor) {
+  const next = await bot.raw('get_qzone_public_feeds', { cursor: page.next_cursor });
+  console.log(next.feeds);
+}
+
+const feed = page.feeds[0];
+if (feed) {
+  const detail = await bot.raw('get_qzone_public_feed_detail', { feed });
+  if (detail.has_more === true && typeof detail.attach_info === 'string') {
+    const comments = await bot.raw('get_qzone_public_comments', {
+      feed,
+      cursor: detail.attach_info,
+    });
+    console.log(comments);
+  }
+}
+```
+
+列表续页必须原样传回 `next_cursor`，根据 `has_more` 判断结束，不能因本页不足 10 条而停止。详情中的首批评论位于 `feed.feed.cell_comment.comments`；后续评论使用详情或上一评论页的 `attach_info` 作为 `cursor`。读取回复时，首次可省略 `cursor` 使用完整评论自带的 `reply_attach_info`，之后传上一回复页的 `reply_attach_info`。这些游标各有用途，列表游标还绑定当前账号。登录或访问权限失败会抛出 `SnowLumaApiError`。
+
+### 单个管理员权限
+
+`set_group_admin` 用于授予或取消管理员身份。对已有管理员，可通过以下动作读取或修改权限；调用账号需要具有 QQ 服务端要求的管理权限。
+
+| 动作 | 参数与结果 |
+| --- | --- |
+| `get_group_admin_permissions` | `group_id`、`user_id`；返回撤回权限、移除权限、每日移除上限和接收验证消息状态 |
+| `set_group_admin_permissions` | `group_id`、`user_id`，以及至少一个 `recall_member_message` / `kick_member` |
+| `set_group_admin_receive_verify` | `group_id`、`user_id`、必填 `enable`；独立设置接收加群验证消息 |
+
+```ts
+await bot.raw('set_group_admin_permissions', {
+  group_id: 123456,
+  user_id: 10001,
+  recall_member_message: false,
+  kick_member: true,
+  kick_member_per_day: 20,
+});
+
+const permissions = await bot.raw('get_group_admin_permissions', {
+  group_id: 123456,
+  user_id: 10001,
+});
+
+await bot.raw('set_group_admin_receive_verify', {
+  group_id: 123456,
+  user_id: 10001,
+  enable: false,
+});
+```
+
+只修改显式提供的权限。开启移除权限必须明确提供 `kick_member_per_day`，支持 `0`、`5`、`10`、`20`、`50`、`100`、`200`，其中 `0` 表示不限。修改上限也须同时传 `kick_member: true`；关闭或省略移除权限时不能提供上限。SDK 的 `kick_member` 使用布尔值，以便类型检查约束上限。
+
+读取结果包含 `group_id`、`user_id`、`recall_member_message`、`kick_member`、`kick_member_per_day`、`receive_verify`。`receive_verify` 表示是否接收加群验证消息。服务器未返回或未指定的状态为 `null`；移除权限关闭或未指定时，上限也为 `null`。各项来自独立查询，不保证同一时刻的状态；任何查询失败都会报错。
+
+两个写动作分别发送一次请求，不自动重试或授予管理员身份。权限写入成功表示服务器确认请求；接收验证消息写入还会核对响应中的群号和成功管理员列表。两者均返回 `null`。完整的客户端显示和实际权限效果仍需真实 QQ 验证，不能以接口成功替代验收。
+
+## Message Builder
+
+```ts
+import { fromCQString, message, text, toCQString } from '@snowluma/sdk';
+
+const segments = [
+  message.reply(42),
+  message.text('收到 '),
+  message.image('https://example.com/a.png'),
+];
+
+const chained = text('收到 ')
+  .at(10001)
+  .image('https://example.com/a.png');
+
+const cq = toCQString(segments);
+const chainedCq = toCQString(chained);
+const parsed = fromCQString('hi[CQ:at,qq=all]');
+```
+
+CQ 转换会保留参数中的字面量转义文本，例如图片路径中的 `,`，不会将它再次解码成逗号。
+
+链式入口返回 `MessageChain`，可以直接传给发送接口，也可以用 `build()` / `toSegments()` 转成 OneBot segment 数组：
+
+```ts
+await bot.sendGroupMessage(123456, text('hi').at(10001).image('/tmp/a.png'));
+
+const segments = text('hi').at('all').build();
+
+await text('hi').atAll().br().face(14).sendToGroup(bot, 123456);
+```
+
+`reply()` 在一条链中只能出现一次；TypeScript 会阻止 `text('a').reply(1).reply(2)`，运行时也会做同样检查。
+
+已内置常用段：`text`、`br`、`face`、`at`、`atAll`、`reply`、`image`、`record`、`video`、`json`、`xml`、`poke`、`forward`、`node`、`share`、`music`、`location`、`contact` 和 `raw`。
+
+### 合并转发中的自定义引用
+
+合并转发节点的 `content` 支持 `reply.data.message`，无需引用目标已存在于本地消息库。
+SDK 提供 `message.customReply()`（返回消息段，仅用于转发节点）：
+
+```ts
+await bot.raw('send_group_forward_msg', {
+  group_id: 123456,
+  messages: [message.node(10001, '发送者', [
+    message.customReply([message.text('SnowLuma')], { qq: 10002, time: 1700000000, seq: 42 }),
+    message.text('这是回复内容'),
+  ])],
+});
+```
+
+对应的 OneBot JSON 为 `{ "type": "reply", "data": { "message": [{ "type": "text", "data": { "text": "SnowLuma" } }] } }`。
+`message` 可以是文本/CQ 字符串、单个消息段或消息段数组，不能为空；显式提供时优先于 `id`。
+引用预览保留文字和 @，图片、表情、语音、视频、文件、转发、JSON/XML 卡片和 Markdown 使用类型文字摘要，不会为引用重新上传媒体。
+引用内容不支持嵌套 `reply`/`node` 或 `music`、`contact`、`poke` 等其他类型；无效内容会返回参数错误。
+
+`qq`、`time`、`seq` 支持整数或整数字符串。省略时分别使用当前节点发送者、节点时间（未指定时为当前时间）和 `1`。
+`qq` 必须是正安全整数，`time` 是 0 到 4294967295 的 Unix 秒，`seq` 是 1 到 4294967295 的序号。
+这些字段用于引用预览；自定义引用不保证能在 QQ 中跳转到原消息。请使用 JSON 消息段传递此扩展；SDK 的 `toCQString` 会拒绝将嵌套消息段转换成 CQ 参数，避免内容被转成 `[object Object]`。
+
+`get_forward_msg` 的回复段仍含 `id`；当 QQ 返回内嵌引用内容时，还会包含 `message` 以及可用的 `qq`、`time`、`seq`。
+将返回节点的 `message` 作为新转发节点的 `content` 即可保留引用预览，无需再通过 `get_msg` 查询引用 ID。
+若 QQ 没有提供引用内容，则只返回原有 `id`。普通群聊/私聊的 `reply.data.id` 用法保持不变。
+
+## 请求控制
+
+每次请求都支持覆盖 `echo`、超时和 `AbortSignal`：
+
+WebSocket 并发请求必须使用不同的 `echo`；重复值会被拒绝。省略时由 SDK 自动生成。
+
+```ts
+const controller = new AbortController();
+
+const status = bot.getStatus({
+  echo: 'healthcheck',
+  timeoutMs: 5_000,
+  signal: controller.signal,
+});
+
+controller.abort();
+await status;
+```
+
+`timeoutMs: 0` 表示关闭该请求的超时控制。
+WebSocket 普通请求的超时从调用时开始，包含等待连接建立和等待响应的总时间，
+连接成功后不会重新计时。等待连接时已超时或取消的请求不会在连接晚到后补发；
+取消单个请求不会关闭其他请求正在使用或等待的共享连接。
+
+## 错误处理
+
+SDK 暴露统一错误基类和更具体的错误类型：
+
+- `SnowLumaApiError`：OneBot 响应失败或 `retcode !== 0`。
+- `SnowLumaAuthError`：鉴权相关 retcode，例如 `1401`、`401`、`403`。
+- `SnowLumaTransportError`：连接、解析、超时、取消等传输层错误基类。
+- `SnowLumaConnectionError`：HTTP fetch / WebSocket 连接或发送失败。
+- `SnowLumaParseError`：响应不是合法 JSON 或不符合 OneBot 响应结构。
+- `SnowLumaTimeoutError`：请求超过 `timeoutMs`。
+- `SnowLumaAbortError`：调用方通过 `AbortSignal` 主动取消。
+
+```ts
+import {
+  SnowLumaApiError,
+  SnowLumaAuthError,
+  SnowLumaTimeoutError,
+} from '@snowluma/sdk';
+
+try {
+  await bot.getStatus({ timeoutMs: 1000 });
+} catch (error) {
+  if (error instanceof SnowLumaAuthError) {
+    throw new Error('SnowLuma access token is invalid');
+  }
+  if (error instanceof SnowLumaTimeoutError) {
+    console.warn(`SnowLuma did not respond in ${error.timeoutMs}ms`);
+  }
+  if (error instanceof SnowLumaApiError) {
+    console.warn(error.retcode, error.wording);
+  }
+}
+```
+
+## 测试建议
+
+- SDK 自身使用 Vitest 覆盖消息构造、事件上下文、WebSocket 响应关联、错误模型和取消逻辑。
+- 对接真实 SnowLuma 时建议使用单独测试账号和测试群，避免把自动化消息发到生产环境。
+- 集成测试里优先显式设置 `echo` 和较短 `timeoutMs`，这样失败时更容易定位是哪一次 action。
+- 发布前运行 `pnpm --filter @snowluma/sdk typecheck`、`pnpm --filter @snowluma/sdk test`、`pnpm --filter @snowluma/sdk build`。
+
+## 子路径导入
+
+```ts
+import { SnowLumaHttpClient } from '@snowluma/sdk/client';
+import { text } from '@snowluma/sdk/messages';
+import { isMessageEvent } from '@snowluma/sdk/events';
+import { SnowLumaApiError } from '@snowluma/sdk/errors';
+```
+
+根入口 `@snowluma/sdk` 仍导出正式公开 API；不再保留旧的根级兼容 barrel 或别名 API。
+
+## Action 同步
+
+SDK 导出 `SNOWLUMA_ACTIONS` 和 `isSnowLumaAction()`。测试会扫描 `packages/core/src/onebot/actions/*.ts` 的 `registerAction()`，确保 SDK action 列表没有落后。
+
+## 项目结构
+
+```text
+src/
+  client/      HTTP / WebSocket client 与 API facade
+  events/      事件上下文、类型守卫、中间件和命令匹配
+  messages/    segment 工厂、MessageChain、CQ 编解码
+  types/       JSON、消息、事件、action 参数和返回类型
+  internal/    SDK 内部工具
+```
+
+## 版本策略
+
+当前包版本为 `0.1.0`。版本规则、发布检查清单和破坏性变更边界见 [VERSIONING.md](./VERSIONING.md)。
+
+## 接收反向 WebSocket 连接
+
+Node 程序可通过 `@snowluma/sdk/node` 的 `createReverseWebSocketServer()` 接受 SnowLuma 的反向连接，按账号使用原有消息监听、动作和流式接口。支持统一连接或分开的 API/Event 通道。配置、鉴权和重连处理见 [REVERSE_WEBSOCKET.md](REVERSE_WEBSOCKET.md)。

+# Reverse WebSocket connections
+
+`@snowluma/sdk/node` can accept OneBot reverse WebSocket connections. SnowLuma
+connects **to your SDK program** and sends events; your program sends actions
+back over that same connection. The ordinary `createWebSocketClient()` continues
+to dial a SnowLuma WebSocket server. Neither SDK entry acts as a QQ implementation
+for NoneBot/AstrBot; SnowLuma's `networks.wsClients` already serves that use case.
+
+```ts
+import { text } from '@snowluma/sdk';
+import { createReverseWebSocketServer } from '@snowluma/sdk/node';
+
+const server = createReverseWebSocketServer({
+  host: '127.0.0.1',
+  port: 3002,
+  path: '/onebot/v11/ws',
+  accessToken: process.env.ONEBOT_ACCESS_TOKEN,
+  // Optional: restrict which accounts may connect, in addition to the token.
+  selfIds: ['10001'],
+});
+
+server.on('error', (error) => console.error('Reverse connection failed', error));
+server.on('rejected', ({ status, reason }) => console.error('Handshake rejected', status, reason));
+server.on('connection', (bot) => {
+  console.log('Connected account', bot.selfId);
+  bot.onMessage(async (_event, context) => {
+    await context.reply(text('received'));
+  });
+});
+server.on('disconnect', ({ client, code }) => console.log('Disconnected', client.selfId, code));
+await server.listen();
+// Await server.close() when shutting down your application.
+```
+
+Configure the matching SnowLuma account with an entry in `networks.wsClients`:
+
+```json
+{
+  "name": "sdk",
+  "url": "ws://127.0.0.1:3002/onebot/v11/ws",
+  "accessToken": "same-token-as-the-sdk-server",
+  "role": "Universal",
+  "messageFormat": "array",
+  "reportSelfMessage": false
+}
+```
+
+Use the address of the SDK host if the two processes run on different machines.
+The listener binds only to loopback by default. Authentication accepts a Bearer
+header or `access_token` query parameter. Empty/omitted tokens mean no token
+check. Account and role headers are still mandatory. No credentials or frame
+bodies are included in handshake rejection events.
+
+## Sessions and channels
+
+`connection` supplies a `SnowLumaReverseWebSocketSession` with `selfId` (string),
+`canCallActions`, `canReceiveEvents` and the existing forward client's helpers:
+`onMessage`, middleware, `waitForMessage`, `getStatus`, message sends, `request`,
+`requestStream`, upload and download helpers. Signed message IDs, response errors,
+timeouts, cancellation and stream limits retain their existing meaning.
+
+`server.getClient(selfId)` and the read-only `server.clients` snapshot expose live
+sessions. Each account owns its pending requests and event handlers. Events must
+match the account declared by `X-Self-ID`; mismatches close the session and report
+an error. Duplicate active channels receive HTTP 409 and do not replace a healthy
+session. An optional account allowlist rejects unknown accounts with HTTP 403.
+
+Universal mode carries both actions and events. For separate channels, configure
+one SnowLuma `Api` connection and one `Event` connection using the same account
+and server address. `API` is also accepted in the wire header. Both share one SDK
+session, so an event handler's `context.reply()` uses the API channel. `connection`
+fires when the first channel arrives; `channel` fires for each accepted channel:
+
+```ts
+server.on('channel', ({ client, role }) => {
+  console.log(client.selfId, role, client.canCallActions, client.canReceiveEvents);
+});
+```
+
+Wait for `canCallActions` before sending actions in split mode. Calling an action
+on an Event-only session fails explicitly. Closing either half ends the entire
+session and its sibling channel. SnowLuma owns reconnect timing; the next
+connection creates a new session and emits `connection` again, where handlers
+should be registered anew. Old session objects cannot reconnect themselves.
+Pending requests, stream iterators and event waits fail on disconnect. Actions
+are never automatically replayed because the remote side may already have
+executed them. This transport does not persist events missed while disconnected.
+
+## Limits, errors and ownership
+
+The defaults are 100 MiB per incoming message, 16 MiB of outgoing buffered bytes
+per channel, 128 simultaneous channels, a 30-second action timeout and a
+30-second ping interval. Configure `maxPayloadBytes`, `maxBufferedBytes`,
+`maxConnections`, `requestTimeoutMs` and `heartbeatIntervalMs` as needed. A zero
+request timeout waits indefinitely; a zero heartbeat interval disables pings.
+Other limits must be positive integers. All timers are cleaned up on close.
+Oversized inbound messages close with 1009; outbound capacity failures reject
+the action without enqueueing it. A peer missing the next ping check is terminated
+(normally within two heartbeat intervals).
+
+Register a server `error` handler: unhandled errors follow Node's EventEmitter
+error contract and throw. Session transport, parsing and asynchronous event-handler
+failures are forwarded there. Invalid peer JSON and cross-account/channel frames
+close the connection; startup bind errors reject `listen()` directly.
+
+To reuse an HTTP or HTTPS server, pass `server` instead of `host`/`port`, after
+that server has started listening. Only the configured upgrade path belongs to
+the SDK. Ordinary requests and other upgrade paths remain with their existing
+handlers. `close()` releases SDK connections and listeners without closing the
+external server. TLS configuration remains with that HTTPS server or your proxy;
+there is no automatic downgrade. Internally owned listeners are closed by the
+SDK. Closing connections have a bounded handshake grace period before termination.
+
+Only the Node subpath imports the `ws` runtime dependency; browser-facing SDK
+entry points retain their existing imports. TypeScript Node consumers should
+include their normal `@types/node` development dependency and enable `"types": ["node"]` in their TypeScript configuration.
+
+Validation uses real local WebSockets and SnowLuma's `WsClientAdapter` with the
+actual action and stream handlers, isolated from QQ accounts. It covers Universal
+and split channels, identity/authentication, message replies, multi-account echoes,
+disconnect cleanup, limits, heartbeat, external-server ownership and published
+NodeNext/bundler package consumers.

+# Streaming files
+
+Both `SnowLumaHttpClient` and `SnowLumaWebSocketClient` support incremental uploads
+and downloads. Existing `request()`, `call()`, `raw()`, `rawResponse()` and
+`downloadFile()` keep their single-response behavior. Use the new methods below
+when a response contains multiple frames.
+
+## Upload
+
+```ts
+import { createReadStream } from 'node:fs';
+import { stat } from 'node:fs/promises';
+import { SnowLumaHttpClient } from '@snowluma/sdk';
+
+const client = new SnowLumaHttpClient({ baseUrl: 'http://127.0.0.1:3000/' });
+const controller = new AbortController();
+const path = './photo.png';
+const file = await client.uploadFileStream(
+    createReadStream(path, { signal: controller.signal }),
+    {
+        fileSize: (await stat(path)).size,
+        filename: 'photo.png',
+        signal: controller.signal,
+        onProgress: ({ uploadedBytes, fileSize }) => {
+            console.log(`${uploadedBytes}/${fileSize}`);
+        },
+    },
+);
+console.log(file.file_path, file.file_size, file.sha256);
+```
+
+`uploadFileStream(source, options?)` accepts `Uint8Array` (including Node.js
+`Buffer`), `Blob`, `ReadableStream` or `AsyncIterable`.
+Byte arrays and blobs provide their own size. Stream sources require `fileSize`:
+the server needs the total chunk count before accepting the first chunk. The SDK
+rejects input whose actual length differs from the declared size.
+
+The default chunk size is 64 KiB. `chunkSize` accepts 1 through 1048576 bytes,
+keeping each encoded request below the standard server HTTP body limit. Input is
+read incrementally; chunks are acknowledged sequentially, and `onProgress` is
+awaited before continuing. Empty files are supported. Completion is a separate
+request and returns `UploadFileStreamComplete`, including the **server's** local
+file path; it does not write a local client file or send a QQ message.
+
+Optional settings are `filename`, `expectedSha256`, `fileRetention` (milliseconds;
+zero disables server expiry), and `streamId`. The default server retention is five
+minutes. A generated ID identifies each upload; an explicit ID must be fresh, not
+an existing upload. The helper does not resume or automatically retry transfers.
+The server validates `expectedSha256` when provided; the SDK checks the completed
+metadata and returned digest against that expectation.
+
+`signal` cancels requests and closes readable sources. For custom async iterables,
+pass the same signal to the source and ensure pending reads and iterator cleanup
+can finish on cancellation (as the `createReadStream` example does). Cancellation
+cannot force an arbitrary producer to resolve its own promises. A failed or
+cancelled upload is not finalized; partial server uploads expire after the
+server's idle timeout (currently ten minutes). The helper does not issue a reset
+request or delete a completed server file automatically.
+
+## Download
+
+```ts
+import { createWriteStream } from 'node:fs';
+import { pipeline } from 'node:stream/promises';
+
+await pipeline(
+    client.downloadFileStream(
+        { file: file.file_path, chunk_size: 64 * 1024 },
+        { onInfo: (info) => console.log(info.file_name, info.file_size) },
+    ),
+    createWriteStream('./downloaded.png'),
+);
+```
+
+`downloadFileStream(params, options?)` yields `Uint8Array` chunks and returns
+`DownloadFileStreamComplete` as the iterator's final value. `for await` and
+`pipeline()` consume chunks and verify completion, but discard that return value;
+call `iterator.next()` manually if you need `total_bytes` and `total_chunks` from
+the final result. `onInfo` runs before any file bytes are yielded.
+
+Parameters accept a server-side `file` or `file_id`, plus optional `chunk_size`.
+The `action` option selects `download_file_stream` (default),
+`download_file_image_stream`, or `download_file_record_stream`.
+
+The helper decodes base64 and checks chunk order, chunk lengths and final counts.
+A zero initial file size can mean unknown size; final byte and chunk totals still
+must match. Missing metadata, malformed frames, truncation and server failures
+throw; bytes already consumed are not rolled back. For durable output, write to
+a temporary file and rename it after the iteration succeeds.
+
+## Individual frames
+
+```ts
+for await (const frame of client.stream('test_download_stream', {})) {
+    console.log(frame.type, frame.data_type);
+}
+
+for await (const response of client.requestStream('test_download_stream', {})) {
+    console.log(response.status, response.retcode, response.data);
+}
+```
+
+- `requestStream()` yields response envelopes, including a final failed envelope.
+- `stream()` yields typed payloads and throws `SnowLumaApiError` (or its auth
+  subtype) for failed envelopes, including errors after earlier chunks.
+- Both support the five streaming actions: the three downloads,
+  `test_download_stream`, and `upload_file_stream`. Each upload request returns
+  just one acknowledgement, including `type: 'stream'` chunk ACKs. Low-level
+  callers must finalize in a separate request. Reset retains the server's
+  existing failed-envelope behavior.
+- `AbortSignal`, `echo`, and `timeoutMs` work as on ordinary requests. Timeout
+  covers an active streaming request (including WebSocket connection setup);
+  uploads apply it to each chunk/finalization request. Zero disables timeout.
+  Source reads and application callbacks are not timed by the request timeout.
+- Stopping iteration releases client resources. HTTP also cancels its response
+  body. WebSocket stops collecting that request without closing the shared socket;
+  the protocol has no per-request download cancellation message, so the server
+  may continue sending remaining frames. Use unique echoes for transfers; do not
+  reuse an aborted transfer's echo while late frames may still arrive.
+- WebSocket disconnection fails active transfers; reconnect does not replay them.
+- `maxBufferBytes` defaults to 32 MiB and bounds each HTTP frame or the queued
+  WebSocket payloads. `maxBufferedFrames` defaults to 256 for WebSocket. An
+  overflow throws instead of dropping frames or buffering the entire file.
+  HTTP reads follow consumption; WebSocket has no per-request backpressure, so
+  prefer HTTP for large downloads to a slow destination.
+
+All new types are exported from `@snowluma/sdk` and `@snowluma/sdk/types`. Custom
+`SnowLumaApiClient` subclasses can opt in by implementing `requestStream()`;
+request-only subclasses remain compatible and receive an explicit unsupported
+error if streaming is attempted.

+# @snowluma/sdk Versioning
+
+The SDK follows SemVer for its public package surface:
+
+- Exported runtime values and classes from `@snowluma/sdk`.
+- Exported types from `@snowluma/sdk` and `@snowluma/sdk/types`.
+- Supported subpath exports: `client`, `messages`, `events`, `errors`, `actions`, `types`, and `node`.
+- Runtime behavior of typed client helpers, message builders, event helpers, and SDK error classes.
+
+## Version policy
+
+SDK and application versions are synchronized by `pnpm bump ` from the repository root.
+
+The current Node.js requirement is `^24.22.1 || >=26.12.1`. Use the repository's `.node-version` for development and builds.
+
+The SDK is an ES module package that supports native Node.js imports and bundler consumers. Its build uses `NodeNext`; relative source imports and re-exports must use `.js` specifiers so both emitted JavaScript and declarations resolve without a bundler. Package tests compile fresh output, load every runtime entry point with Node.js, and typecheck consumers with both NodeNext and bundler resolution.
+
+- Major: removes or changes a public export, changes runtime behavior incompatibly, changes supported Node version, or removes/changes an existing package subpath.
+- Minor: adds new public API or package subpaths, supports new SnowLuma actions, adds optional parameters, or adds error subclasses.
+- Patch: fixes bugs, improves docs, narrows implementation details without breaking public types, or updates action metadata without changing call signatures.
+
+## Release Checklist
+
+1. Run `pnpm bump ` to update all workspace versions.
+2. Update `packages/sdk/CHANGELOG.md`.
+3. Run `pnpm --filter @snowluma/sdk typecheck`.
+4. Run `pnpm --filter @snowluma/sdk test`.
+5. Run `pnpm --filter @snowluma/sdk build`.
+6. Run `pnpm --filter @snowluma/sdk pack --dry-run` to inspect published files.
+
+## Automated npm Publish
+
+`.github/workflows/sdk-npm-publish.yml` publishes `@snowluma/sdk` when SDK-related files reach `main`, including the automated `dev` to `main` promotion flow. The publish job uses npm Trusted Publishing with the GitHub Environment named `SnowLuma`; it authenticates through GitHub Actions OIDC and does not require an `NPM_TOKEN` secret.
+
+The one-time npm settings for SDK, UI, and MCP are documented in
+[`.github/npm-trusted-publishing.md`](../../.github/npm-trusted-publishing.md).
+
+If the package version already exists on npm, the workflow skips publishing that run. Bump `packages/sdk/package.json` before merging SDK changes that should create a new npm release.
+
+## Action Compatibility
+
+`SNOWLUMA_ACTIONS`, `isSnowLumaAction`, and `SnowLumaKnownAction` are available from both `@snowluma/sdk` and `@snowluma/sdk/actions`. The catalog includes this release's executable action names, compatibility aliases, and raw actions. OneBot's registry tests verify that the SDK catalog stays aligned with the server; the published SDK does not import server code.
+
+This local catalog is not a capability check against a connected server. Every known action name has a parameter and result entry in `SnowLumaActionMap`, including aliases. Existing broad JSON contracts are retained for compatibility. New parameter types describe accepted input forms, including numeric strings and primitive coercions; server-side range and state validation still applies. Custom actions and dynamically selected names remain supported through `raw()` and `rawResponse()`. Adding an action type is a minor change unless it changes an existing method signature or return type.
+
+Stream result types describe individual frame payloads, including intermediate and terminal frames. Both built-in clients support `requestStream()` (envelopes) and `stream()` (payloads with API error handling), plus incremental file upload/download helpers; see [STREAMING.md](STREAMING.md). Existing `request()`, `call()`, `raw()`, `rawResponse()` and `downloadFile()` keep their single-response contracts. Custom subclasses that only implement `request()` remain valid; the default `requestStream()` explicitly reports unsupported streaming. Stream reset/error envelopes retain their existing error behavior. Album counts and IDs returned as decimal strings stay strings, and ordinary message IDs remain signed numbers.
+
+The package consumer tests check complete action-map coverage, inferred results, compatibility aliases, and invalid input examples with both NodeNext and bundler resolution. The same parameter examples are checked against the server's real action parsers without starting QQ or executing actions.
+
+Additive media-send methods, explicit quoted replies, and WebSocket event waits are described in [MESSAGING.md](MESSAGING.md). Existing string paths, ordinary `reply()` behavior, and handler/context types remain supported. The optional `node` subpath owns local filesystem access; browser-facing entry points stay free of Node imports. The runtime also propagates group-file chat publication failures instead of returning success after a failed publication; successful action response shapes are unchanged.
+
+The optional `node` entry also exports `createReverseWebSocketServer`, `SnowLumaReverseWebSocketServer`, and reverse-session types. These additive exports accept OneBot reverse connections without changing the forward client. The `ws` runtime dependency is loaded only by the Node entry; browser-facing exports remain free of Node server imports. See [REVERSE_WEBSOCKET.md](REVERSE_WEBSOCKET.md).

+# Host appearance overlays
+
+Set `SNOWLUMA_WEBUI_TARGET=maibot` on the **SnowLuma process** to use MaiBot's
+millennium appearance. The same release bundle supports standalone and embedded
+deployments. An unset or empty value keeps the existing SnowLuma experience;
+unknown values fail WebUI startup with an explicit diagnostic.
+
+This first adapter implements **millennium only**, in light and dark modes.
+Other MaiBot styles are not implemented. There is no new appearance selector in
+SnowLuma. The host owns theme changes; existing theme controls are unavailable
+while managed, and the settings page explains which preferences are preserved.
+
+## Runtime and ownership
+
+1. Core reads the environment at startup. [Static document delivery](../core/src/webui/static-frontend.ts)
+   injects a validated, public JSON bootstrap into `/`, `/index.html` and SPA
+   fallback documents. Documents use `Cache-Control: no-store`. No secrets or
+   arbitrary environment variables reach the browser.
+2. [Frontend bootstrap](src/appearance/runtime.ts) loads only the selected
+   target's assets before mounting React. Standalone deployments load no target
+   stylesheet, font or host listener. Vite development serves the same bootstrap
+   when its process has the environment variable; production builds remain neutral.
+3. [ThemeContext](src/contexts/ThemeContext.tsx) keeps `savedAppearance` separate
+   from effective `appearance`. Only saved preferences enter localStorage or
+   `config/ui.json`. Target updates never invoke the persistence API.
+4. The target owns colors, fonts, radius, wallpaper, CSS variable overrides,
+   custom CSS and custom cursor presentation. These saved values are preserved
+   but suspended. UI scale, density, motion/accessibility, navigation layout and
+   data preferences remain available. Safe-mode restrictions still apply when
+   returning to native appearance.
+5. A single layout effect applies effective appearance. Changes do not reload
+   the document, change React keys or restart sessions. All target rules are
+   scoped to `html[data-webui-target]`, including portals under `body`.
+
+## Host protocol, version 1
+
+The contract lives in [common/webui-target.ts](../common/src/webui-target.ts).
+The deployment environment is an opt-in, **not a live transport**. Existing
+launchers need to implement the sender below; merely setting the environment
+variable cannot convey another process's current theme.
+
+A same-document embedding bridge (for example Electron `executeJavaScript`)
+publishes the latest snapshot before dispatching the event:
+
+```js
+const appearance = {
+    version: 1,
+    target: 'maibot',
+    style: 'millennium',
+    mode: 'dark', // 'light' | 'dark' | 'system'
+};
+window.__SNOWLUMA_HOST_APPEARANCE__ = appearance;
+window.dispatchEvent(new CustomEvent('snowluma:host-appearance', { detail: appearance }));
+```
+
+The snapshot handles messages sent before React or the lazy asset loader is
+ready. Publish on each guest `dom-ready` and whenever the host's resolved
+brightness changes. A host that already follows MaiBot should forward its own
+resolved `light`/`dark` state; this avoids competing sources of truth. Validate
+the guest's expected origin before injecting, serialize values with
+`JSON.stringify`, and do not enable Node integration in the guest.
+
+Send `{ version: 1, target: null }` using the same mechanism to release the
+override for the current document. The original appearance returns immediately.
+The opted-in document keeps its host subscription so the host can reapply the
+target later. Listeners are released on provider unmount. This does not change
+the startup environment or enable a target in a standalone deployment.
+
+The current adapter starts with millennium and system brightness before a host
+snapshot arrives. The last valid snapshot remains active if the host stops
+sending. Snapshots are not persisted or shared across origins/tabs. A reload
+requires the host to publish again. Unsupported versions, targets, styles or
+modes are rejected with `[SnowLuma appearance]` console diagnostics; the previous
+valid snapshot remains. The host cannot supply CSS, URLs or executable content
+through this protocol. No unauthenticated HTTP write endpoint is introduced.
+
+## Adding a target
+
+- Add its identifier, styles and default style to `WEBUI_TARGETS` in the shared
+  contract. Keep validation at this boundary; do not accept arbitrary strings.
+- Add one lazy loader to the exhaustive [frontend registry](src/appearance/registry.ts).
+  Implement a pure saved-to-effective resolver and scoped stylesheet under
+  `src/appearance/targets`. Keep any fonts local with their redistribution license.
+- Use semantic color variables, shared component classes and neutral
+  `data-ui-surface` markers. Do not add target-name checks to business pages.
+- Never persist resolved overrides, mutate saved preferences, introduce a
+  second DOM theme writer, or remount the application to switch presentation.
+- Test default asset/listener isolation, initial document routes, malformed
+  messages, rapid updates, cleanup and exact restoration of saved preferences.
+  Verify forms, focus, scroll, portals and mobile layout with an isolated backend.
+  Electron integration needs a separate real-host check.
+
+## Sources and checks
+
+The adapter follows the main MaiBot repository's
+[millennium stylesheet](https://github.com/Mai-with-u/MaiBot/blob/5c7637e6913c84d1c3d5e742fa9e95a7e70d3501/dashboard/src/styles/millennium.css),
+not the archived standalone WebUI. Colors/materials also match the
+[OneKey shell](https://github.com/Mai-with-u/MaiBotOneKey/blob/e8073b0bce35c8c4da973b06156602e14c42fee5/src/renderer/src/styles/millennium.css).
+The bundled Jersey 20 font is from that MaiBot revision, copyright The Soft Type
+Project Authors, under the [SIL Open Font License](src/appearance/targets/assets/Jersey20-OFL.txt).
+Its license is emitted alongside the font in production assets.
+
+Focused checks (from the repository root):
+
+```sh
+pnpm --filter @snowluma/common exec vitest run tests/webui-target.test.ts
+pnpm --filter @snowluma/core exec vitest run tests/webui-static-frontend.test.ts
+pnpm --filter webui exec vitest run tests/target-appearance.test.ts
+```
+
+Run the normal workspace checks from `AGENTS.md` before handing off changes.

+# SnowLuma WebUI
+
+SnowLuma's browser console is a Vite + React application for managing runtime
+status, OneBot configuration, logs, storage, and server settings.
+
+## Default appearance
+
+New installations and appearance resets use the mascot's lavender accent.
+The light variant uses a deeper purple for readable button labels; dark mode
+uses a softer lavender. Existing saved accents and custom colors are preserved.
+The original sky-blue accent remains available in Settings.
+
+With the default palette, page, card, input, popover and sidebar surfaces mix a
+small amount of the active accent into neutral light/dark backgrounds. Text stays
+neutral for readability. Sidebar-only accents tint only the sidebar; OLED keeps a
+true-black canvas. Named palettes, custom CSS variables and host appearance
+overlays retain control of their own surfaces.
+
+Keep the server defaults in `packages/core/src/webui/ui-config.ts`, the frontend
+defaults and preset in `src/contexts/ThemeContext.tsx`, and the pre-mount tokens
+in `src/index.css` aligned when changing the default accent.
+
+The browser favicon, home-screen icon and in-app logo share the mascot avatar
+in [`assets/brand/mascot-avatar.png`](../../assets/brand/mascot-avatar.png).
+Its exported sizes live in `public/`: `logo.png` (512 px), `favicon.png` (64 px),
+and `apple-touch-icon.png` (180 px). Export from the master without redrawing
+individual sizes.
+
+## Host appearance integration
+
+`SNOWLUMA_WEBUI_TARGET=maibot` opts a deployment into a reversible millennium
+appearance overlay. Standalone defaults are unchanged. Hosts drive live light/dark
+updates without saving over personal preferences or adding another selector.
+See [the integration contract and extension guide](INTEGRATIONS.md) before changing
+target startup, theme ownership, host messaging or scoped styles.
+
+## Interaction conventions
+
+- Destructive actions and second confirmations stay in modal dialogs.
+- Operations that may take time show a bottom-right running state.
+- Completed and failed operations use bottom-right result notices that close
+  automatically after a visible countdown.
+- Routine, high-frequency adjustments should not generate a notice for every
+  intermediate edit.
+- Foreground polling pauses in hidden tabs and waits for each request to finish
+  before scheduling the next. Connection-state polling runs only while SSE clients
+  are subscribed.
+- Data-backed surfaces use the Interior Skeleton Swap defaults (120 ms delay,
+  380 ms minimum visibility) so fast local responses do not flash a placeholder.
+  Submission, upload, and other explicit operation progress keeps its spinner.
+- Variable-height content must release the skeleton's reserved box after it is
+  ready; do not introduce a second scrolling region inside the page.
+- The mobile navigation menu uses a controlled Icon Morph whose visual state
+  follows the actual drawer state.
+- Failures must remain visible in the affected control and in the operation
+  result; do not convert failed responses into successful feedback.
+- JSON endpoints must return an object. Malformed or non-object responses are
+  reported as errors rather than displayed as empty lists or default settings.
+- Configuration responses include `config`; saves also report `saved`, `applied`,
+  `online`, `errors`, and `message`. The UI uses these fields without legacy aliases
+  or a second request after saving.
+- Password change flows use floating labels and inline validation consistently.
+- Password strength details appear only while the new-password field has focus
+  and leave with the same motion language when focus moves away.
+- The first-run wizard keeps agreement text as the primary reading surface and
+  aligns each step's actions inside one responsive footer. Settings includes a
+  visible developer page for safely replaying this wizard and exercising the
+  page-level crash screen; replayed consent and passwords are never persisted.
+
+## Authentication behind a reverse proxy
+
+Authenticated WebUI requests send the session token in `X-SnowLuma-Token`, leaving
+`Authorization` available for the reverse proxy's HTTP authentication (such as
+Nginx Basic Auth). Forward `X-SnowLuma-Token` unchanged if the proxy filters
+request headers. The backend still accepts `Authorization: Bearer ` for
+existing clients when the dedicated header is absent. Both layers still require
+their own valid credentials.
+
+Late authentication failures from an old session do not sign out a newer session.
+Live streams release subscriptions on disconnect and pause with the page.
+Malformed stream data is reported; a debug stream invocation fails instead of silently succeeding.
+
+## Process account detection
+
+Process cards use QQ's local account data before injection and the hook's confirmed
+identity after login. Missing local data means the account is unknown. It does not
+prove that QQ is signed out, and local detection alone never marks a bridge online.
+The manual login probe and `/api/processes/:pid/probe-login` endpoint are removed.
+
+Linux resolves data roots from each QQ process's `XDG_CONFIG_HOME` or `HOME`.
+Windows uses the bundled addon’s `getFileHoldersAsync` to find the process holding
+each account database. Query failures are reported instead of treated as no login.
+
+## Account notification templates
+
+Webhook bodies and email subjects/bodies support `{uin}`, `{nickname}`, `{event}`
+(`offline` or `online`), `{time}`, `{status}` (Hook process state), `{pid}`, and
+`{error}` (Hook process error). New webhook and email channels include process
+status in their default body; existing saved templates are preserved.
+JSON templates escape substituted strings, including quotes, line breaks and control characters.
+
+Process facts are resolved when the notification is dispatched, after any offline
+debounce. Each transition carries its process PID, including the final PID detached
+when an account goes offline. Facts are looked up for that PID and UIN without
+substituting another process. Missing facts render empty and mean unknown, not
+proof that QQ exited. Hook status alone does not identify the cause of a QQ login
+failure. Notifications for one account are delivered in transition order; a slow
+account does not delay other accounts.
+
+## Local development
+
+Packaged installations offer download and restart controls in Settings → About.
+Downloads are verified and staged; files are applied before the application starts.
+Restart confirmation uses the shared modal, and download results use action feedback.
+
+On Windows, the native API logs the process token and EXE integrity label once
+at startup. A Low (or lower) token triggers a WebUI warning; file labels and
+query failures alone do not. “临时关闭” lasts for the tab session, including
+reloads; “永久关闭” persists in this browser's site storage. Neither suppresses
+startup logs. Failed queries and preference writes remain visible.

+// ActionTester — the debug console's centrepiece. Pick an account + action and
+// invoke it; params render as role-driven smart controls (pickers, switches,
+// file sources) with a raw-JSON escape hatch. Read-only actions are badged
+// green, side-effecting ones amber; destructive ones confirm first. Stream API
+// actions invoke over the streaming transport and render frames live (tracked
+// in the app-level task registry). Every call lands in localStorage history
+// with one-click replay. Responses render in a collapsible JsonTree.
