+## English
+
+### Reporting a Vulnerability
+
+**Please do not report security vulnerabilities through public GitHub issues, pull requests, or discussions.**
+
+Report them privately through GitHub's private vulnerability reporting:
+
+**[Report a vulnerability](https://github.com/Wei-Shaw/sub2api/security/advisories/new)**
+
+(Repository → **Security** tab → **Report a vulnerability**.) Only the maintainers can see the report, and the advisory becomes the place to discuss, fix, and eventually publish the issue.
+
+If you cannot use GitHub private vulnerability reporting, email **dev@sub2api.org** instead, with `[Security]` in the subject line.
+
+A useful report includes:
+
+- The affected component and version (release tag or commit)
+- Impact: what an attacker can do and which privileges they need
+- Minimal reproduction steps or a proof of concept
+- Any non-default configuration required to trigger the issue
+- A suggested fix, if you have one
+
+### Supported Versions
+
+Sub2API releases frequently, and fixes ship in a new release rather than being backported.
+
+| Version | Supported |
+| ------- | --------- |
+| Latest release | ✅ |
+| Older releases | ❌ |
+
+Please confirm that the issue reproduces on the latest release or on `main` before reporting.
+
+### Scope
+
+In scope: the Sub2API backend, frontend, official Docker images, and deployment files in this repository.
+
+Usually out of scope:
+
+- Issues that require already-compromised admin credentials or server access
+- Risks arising from explicitly weakening documented security settings (for example, disabling `security.url_allowlist`)
+- Vulnerabilities in upstream AI providers or third-party dependencies with no Sub2API-specific impact (please report those upstream)
+- Missing best-practice headers or scanner output without a demonstrated impact
+
+### Disclosure Process
+
+1. We acknowledge the report and assess its validity and severity.
+2. We develop a fix privately in the advisory and may ask you to verify it.
+3. We publish a release containing the fix, then publish the GitHub Security Advisory (with a CVE when applicable), crediting you unless you prefer to stay anonymous.
+
+Please keep details private until the advisory is published. This is a volunteer-maintained project, so response times are best effort.
+
+## 中文
+
+### 报告漏洞
+
+**请不要通过公开的 Issue、Pull Request 或 Discussion 报告安全漏洞。**
+
+请使用 GitHub 私密漏洞报告功能提交：
+
+**[提交漏洞报告](https://github.com/Wei-Shaw/sub2api/security/advisories/new)**
+
+（仓库 → **Security** 标签页 → **Report a vulnerability**。）报告仅维护者可见，后续的讨论、修复与公告发布都在该安全公告中进行。
+
+如果无法使用 GitHub 私密漏洞报告，也可以发送邮件至 **dev@sub2api.org**，邮件标题请注明 `[Security]`。
+
+报告中建议包含：
+
+- 受影响的组件与版本（Release tag 或 commit）
+- 影响：攻击者能做什么、需要什么权限
+- 最小复现步骤或 PoC
+- 触发问题所需的非默认配置
+- 修复建议（如有）
+
+### 支持的版本
+
+Sub2API 发版频繁，安全修复随新版本发布，不向旧版本回移。
+
+| 版本 | 是否支持 |
+| ---- | -------- |
+| 最新 Release | ✅ |
+| 更早的版本 | ❌ |
+
+报告前请先确认问题在最新 Release 或 `main` 上仍可复现。
+
+### 范围
+
+范围内：本仓库中的 Sub2API 后端、前端、官方 Docker 镜像与部署文件。
+
+通常不在范围内：
+
+- 需要事先已掌握管理员凭据或服务器权限才能利用的问题
+- 因主动关闭文档中的安全配置（如关闭 `security.url_allowlist`）而产生的风险
+- 上游 AI 服务商或第三方依赖自身的漏洞，且对 Sub2API 无特定影响（请向上游报告）
+- 仅缺少最佳实践响应头或扫描器输出，但未证明实际影响
+
+### 披露流程
+
+1. 我们确认收到报告，并评估其有效性与严重程度。
+2. 我们在安全公告中私下开发修复，可能请你协助验证。
+3. 我们先发布包含修复的版本，再公开 GitHub 安全公告（适用时申请 CVE），并致谢报告者（如你希望匿名则不署名）。
+
+在公告发布前请勿公开漏洞细节。本项目由志愿者维护，响应时间尽力而为。

+# Release matrix
+
+The release workflow builds the frontend once, then runs each configured Go target on its own Linux runner. `CGO_ENABLED=0` permits cross-compilation. The target matrix is read from `.goreleaser.yaml`, including its exclusions; simple releases select Linux amd64 only.
+
+Each build uses GoReleaser OSS in snapshot mode with the selected release version and one target. Archive naming, bundled files, Go flags and release templates remain in the existing GoReleaser configurations. Every archive is accompanied by its source commit, target, version and SHA256. The publishing job verifies the complete matrix before building images or publishing. It uses GoReleaser's `extra_files` support to publish existing archives and checksums, with builds disabled. No Pro license is needed.
+
+Go caches are isolated by target and refreshed on each source commit, with fallback to the preceding target cache. Save uses the original restore key, even if a build hook changes `go.sum`. Matrix jobs upload uniquely named artifacts. The publishing job extracts only the regular Linux binary from each verified archive and restores its executable permission before constructing Docker contexts. QEMU remains limited to runtime-image instructions. DockerHub images are omitted when its credentials are absent; GHCR is always retained. Simple mode still publishes only the amd64 GHCR image and the simple release description.
+
+All build jobs use the commit resolved by `prepare`, including a manual release's selected tag. Helper scripts come from the workflow revision and are passed as a run-local artifact, so older application tags do not need to contain the new scripts. The workflow serializes release runs to prevent simultaneous updates to moving image tags.
+
+## Validate without publication
+
+From a branch containing this workflow:
+
+```bash
+gh workflow run release.yml --ref <branch> \
+  -f tag=<branch> -f dry_run=true -f simple_release=false
+```
+
+A dry run builds all selected archives and both runtime images, verifies artifact provenance and produces the final checksum file. It exports images locally as OCI archives instead of pushing them. It skips registry logins, GitHub Release publication, DockerHub description updates, Telegram notifications and VERSION synchronization. Test the simple path separately with `simple_release=true`.
+
+Dry-run artifacts are available in the Actions run, including `release-dry-run-report`. Compare job start/end times, GoReleaser's build duration and cache restore results. Do not present an initial cold-cache run as a warmed-cache benchmark; publishing network time is not measured by dry runs.
+
+Helper checks:
+
+```bash
+python -m pip install -r .github/release-tools/requirements-release.txt
+python -m unittest discover -s .github/release-tools -p 'test_release_matrix.py'
+bash -n .github/release-tools/release-images.sh

The default is `true`; disabling it does not delete existing groups or change runtime auto-binding or admin concurrency setup.

+- Window enforcement uses the database as its source of truth and records only API-key window usage. It is a post-request soft cap, so concurrent in-flight requests can overshoot by their final costs. Historical simple-mode usage is not backfilled.

+## TypeSafe / Jev Support
+
+Sub2API supports TypeSafe API-key accounts through Jev's native, non-streaming System One protocol.
+
+- Platform: `typesafe`; account type: API Key
+- Default upstream: `https://api.typesafe.ai`
+- Public endpoint: `POST /v1/systemone`
+- Model: `jev-latest`, also returned by `/v1/models` for TypeSafe groups
+- Questions: `noul`, `choice`, and `score`
+
+Requests and successful responses retain the native System One JSON structure. This endpoint is not compatible with Chat Completions, Responses, Anthropic Messages, or streaming clients.
+
+Question validation follows the TypeSafe OpenAPI wire schema (also used by SDK v0.5.7). `instructions` may be omitted or `null` for all question types. Noul `criteria` may be omitted or `null`; its `true`/`false` descriptions and Choice descriptions accept strings, objects, arrays, or `null`. Score `criteria` must be a non-empty array of string, object, or array descriptions; a single level is valid. SDK integer-keyed Score maps are normalized to arrays by the SDK before sending.
+
+```bash
+curl https://your-sub2api.example.com/v1/systemone \
+  -H 'Authorization: Bearer sk-your-sub2api-key' \
+  -H 'Content-Type: application/json' \
+  --data '{"model":"jev-latest","state":"Text to evaluate","questions":{"safety":{"type":"noul","instructions":"Evaluate whether the text is unsafe"}}}'
+```
+
+The built-in `jev-latest` price is `$0.042` per million input tokens and `$0` for output tokens. Channel pricing can override both values. Credential, billing, permission, rate-limit, overload, server, and network failures (`401`, `402`, `403`, `429`, `529`, `5xx`, transport errors) use the existing account error policy (including custom error codes and temporary-unschedulable rules) and fail over to another account; request errors (`400`, `413`, and `422`) are returned without retrying another account and never change account state. TypeSafe groups (and Composite requests routed to TypeSafe) reject Messages, Chat Completions, Responses, and count_tokens requests with `404`.

+- 默认每次启动会补齐默认分组。设置 `SIMPLE_MODE_AUTO_CREATE_DEFAULT_GROUPS=false`（或 YAML `simple_mode.auto_create_default_groups: false`）可自行管理分组。默认值为 `true`；关闭后不删除已有分组，不改变运行时自动绑定或管理员并发设置。
 - 功能差异：隐藏 SaaS 相关功能，跳过计费流程
+- 可选密钥窗口：设置 `SIMPLE_MODE_KEY_RATE_LIMIT_ENABLED=true` 后，按每个 API Key 配置的 5 小时、1 天、7 天消费窗口进行限制，默认值为 `false`；启用后仍跳过余额和订阅扣费。
+- 窗口限制以数据库为准，只记录 API Key 窗口用量。它在请求完成后记账，并发中的请求可能以各自最终费用超过窗口上限。启用前的历史用量不会自动补算。
 - 安全注意事项：生产环境需同时设置 `SIMPLE_MODE_CONFIRM=true` 才允许启动

+## TypeSafe / Jev 使用说明
+
+Sub2API 支持使用 TypeSafe API Key 账户，通过 Jev 原生、非流式的 System One 协议调用模型。
+
+- 平台：`typesafe`；账号类型：API Key
+- 默认上游：`https://api.typesafe.ai`
+- 对外端点：`POST /v1/systemone`
+- 模型：`jev-latest`，TypeSafe 分组的 `/v1/models` 也会返回该模型
+- 问题类型：`noul`、`choice`、`score`
+
+请求和成功响应保持 System One 原生 JSON 结构。该端点不兼容 Chat Completions、Responses、Anthropic Messages 或流式客户端。
+
+问题校验遵循 TypeSafe OpenAPI 的线上协议 schema（SDK v0.5.7 也使用该 schema）。所有问题的 `instructions` 都可以省略或为 `null`。Noul 的 `criteria` 可以省略或为 `null`，其中 `true`/`false` 的描述和 Choice 描述支持字符串、对象、数组或 `null`。Score 的 `criteria` 必须是至少包含一档描述的数组，每档支持字符串、对象或数组；单档也合法。SDK 的整数键 Score 映射会由 SDK 在发送前转换为数组。
+
+```bash
+curl https://your-sub2api.example.com/v1/systemone \
+  -H 'Authorization: Bearer sk-your-sub2api-key' \
+  -H 'Content-Type: application/json' \
+  --data '{"model":"jev-latest","state":"待评估文本","questions":{"safety":{"type":"noul","instructions":"评估文本是否不安全"}}}'
+```
+
+`jev-latest` 内置价格为输入 `$0.042/百万 tokens`、输出 `$0`，渠道定价可以覆盖。凭据、欠费、权限、限流、过载、服务端和网络错误（`401`、`402`、`403`、`429`、`529`、`5xx`、传输错误）沿用现有账号错误策略（含自定义错误码与临时不可调度规则）并切换账号；请求错误（`400`、`413`、`422`）不会切换账号重试，也不会改变账号状态。TypeSafe 分组（以及路由到 TypeSafe 的 Composite 请求）调用 Messages、Chat Completions、Responses、count_tokens 时返回 `404`。
