+# 登录开关与外部账号首次授权
+
+超级管理员在“系统配置”中分别控制本地密码登录和本地账号自行注册，默认都开启。关闭密码登录后，本地注册也暂时不可用，因为当前注册流程会建立本地会话；注册开关的原值会保留。关闭密码登录还会阻止密码重置、密码修改和直接密码认证。已有会话按原有效期结束，不会立刻踢下线。
+
+关闭密码登录前，页面会提示可能失去管理入口，但允许继续。部署方应先确认至少有一位超级管理员能通过外部身份登录。若锁定管理入口，使用受控数据库操作恢复 `system_setting` 中 `auth.local` 的 `passwordLoginEnabled`，并记录操作；仅修改启动参数不会覆盖已有数据库设置。
+
+## 空库初始化
+
+仅在数据库没有对应记录时，启动参数提供初始值：
+
+| 环境变量 | Helm 值 | 默认值 |
+| --- | --- | --- |
+| `SKILLHUB_AUTH_INITIAL_PASSWORD_LOGIN_ENABLED` | `auth.initialSettings.passwordLoginEnabled` | `true` |
+| `SKILLHUB_AUTH_INITIAL_SELF_REGISTRATION_ENABLED` | `auth.initialSettings.selfRegistrationEnabled` | `true` |
+| `SKILLHUB_AUTH_INITIAL_ROLE_GRANTS_JSON` | `secrets.initialRoleGrantsJson` | `[]` |
+
+首次授权规则的 JSON 示例：
+
+```json
+[{"provider":"feishu","email":"admin@example.com","role":"SUPER_ADMIN"}]
+```
+
+规则仅在第一次初始化且 `user_account` 为空时写入；初始化标记防止以后删除规则再重启时重复创建。正式环境请通过 Secret 提供 JSON，不要将实际邮箱写进公开的 values 文件。初始化以后，数据库和“系统配置”页面是权威来源。
+
+## 授权边界
+
+规则按身份来源代码和**已验证邮箱**匹配。只有外部身份通过现有准入策略、并且新账号首次创建为可用状态时，才给新账号授予选定平台角色；规则随后标为“已授权”，不会再次使用。拒绝或待审批的登录不会触发授权，规则不会绕过准入策略。已有账号请在“用户管理”中直接授权。相同邮箱的本地账号不会因此合并或获得角色。
+
+后台可以新增规则、调整待匹配规则的角色、停用规则，并查看已使用规则的匹配身份和授权账号。只允许超级管理员操作；修改带版本号，避免两个管理员同时改动时后写覆盖前写。紧急恢复可通过受控数据库操作处理，并保留审计记录。

+## Context
+
+当前 `OAuthLoginFlowService` 每次外部登录都先调用 `AccessPolicy.evaluate`，只有 `ALLOW` 才进入 `IdentityBindingService.bindOrCreate`。主线新增的统一身份核心在公开 OAuth 路径仍保留旧 `identity_binding` 写入权威；`LegacyPlatformIdentityCoreBridge` 不执行按已验证邮箱关联旧账号，不能把本需求实现成邮箱自动合并。现有四种可配置准入策略实际只返回 `ALLOW` 或 `DENY`；`PENDING_APPROVAL` 是预留分支。外部身份以 `(provider_code, subject)` 绑定用户，已验证邮箱才可作为可信邮箱。平台已有 `SUPER_ADMIN`、`SKILL_ADMIN`、`USER_ADMIN`、`AUDITOR` 角色；后台用户管理一次设置一个平台角色。现有 `BootstrapAdminInitializer` 会在启用时于每次启动检查并补建本地密码超管，它不是本方案的一次性外部角色规则。
+
+## 术语
+
+- **普通准入**：外部身份能否进入 SkillHub 的现有策略判断，与平台角色授予分开。
+- **首次角色授权规则**：部署方为指定外部来源和已验证邮箱预设的单次平台角色授予。它只作用于首次创建的 SkillHub 账号。
+- **已消费规则**：已绑定一个 `(provider_code, subject)` 和 SkillHub 用户并完成角色写入的规则。停用或删除未消费规则不撤销历史角色。
+- **运行设置**：由数据库管理、后台可修改的非秘密系统行为设置；不同于 OAuth 密钥等部署秘密。
+
+## Decisions
+
+### 1. 统一页面、分表持久化
+
+“系统配置”页面分为“本地认证”和“外部账号首次授权”两部分。`system_setting` 保存少量经过代码注册、定型和校验的运行设置，不提供任意键值编辑。首批设置键 `auth.local` 的 JSON 对象包含 `passwordLoginEnabled` 和 `selfRegistrationEnabled`，两者默认均为 `true`。同一行更新这组设置，并使用版本号进行条件更新，避免并发管理操作互相覆盖。
+
+建议表结构：`id BIGSERIAL PRIMARY KEY`、`setting_key VARCHAR(128) UNIQUE NOT NULL`、`value_json JSONB NOT NULL`、`version BIGINT NOT NULL`、`created_at/updated_at TIMESTAMP NOT NULL`、`updated_by VARCHAR(128) NULL`。数据库约束验证 JSON 为对象；应用按设置键验证完整字段、类型和允许值。`id` 可用作现有 `audit_log.target_id`。审计记录操作者、旧值、新值和时间；不得把秘密配置写入设置或审计详情。
+
+认证路径直接读取数据库中已持久化的安全开关。首版不使用单节点内存缓存，以免多副本部署时设置失效不一致；读取失败应返回服务错误，不能以默认“开启”放行。前端只读取可公开的认证能力投影，不暴露通用设置读写接口。
+
+### 2. 两个本地开关保持独立
+
+关闭密码登录后，所有发起新本地密码认证的路径均拒绝，包括现有 direct 本地认证路径；密码重置和密码修改操作也不再提供。由于当前本地注册成功会立即建立会话，即使自行注册开关的存储值仍为开启，本地注册也必须暂时不可用；重新开启密码登录后恢复该开关原有值。登录页不展示本地密码表单、注册和重置密码入口，个人设置不展示密码修改入口，直接访问相关页面得到明确的不可用提示。已有会话不批量失效，按现有会话生命周期结束。
+
+关闭自行注册后，仅本地注册 API 和页面不可用。已有本地账号仍可密码登录、重置密码和修改密码；外部身份首次进入仍遵守现有普通准入策略，不受此开关影响。
+
+超级管理员关闭密码登录时，页面明确提示若外部登录不可用可能失去管理入口；服务端不强制阻止保存。外部身份提供方实际连通性无法由“已配置”推断，部署方负责核验。紧急恢复使用受控数据库操作。
+
+### 3. 普通准入优先，首次创建才授权
+
+外部登录顺序为：验证外部身份 → 执行现有普通准入 → 若为 `ALLOW`，按 `(provider_code, subject)` 查找或创建 SkillHub 账号 → **仅新建 ACTIVE 账号**匹配首次角色规则 → 在同一事务中写入角色、规则消费状态和身份绑定 → 生成包含新角色的登录主体及会话。`DENY` 不创建账号、不消费规则、不授予角色。已存在账号即使后来新增规则，也不在下次登录时自动授权；使用现有用户管理页面人工修改角色。后续每次外部登录仍按现有逻辑重新检查普通准入。
+
+首版规则以 `provider_code` 和规范化的**已验证邮箱**匹配。未返回邮箱、邮箱未验证、来源不匹配或账号已存在都不授予角色。匹配成功后记录实际 `(provider_code, subject)` 和用户 ID；规则不能因邮箱回收而再次授予另一身份。后台为每条规则选择一个现有平台角色，不创建自定义角色或命名空间角色，也不把角色写死为 `SUPER_ADMIN`。规则消费后修改或停用不改动已写入 `user_role_binding` 的角色。
+
+现有公开 OAuth 账号不按邮箱自动合并：即使本地账号已经使用相同邮箱，首次进入的外部身份仍会创建独立账号；若命中规则，角色授予这个新外部账号，不授予本地账号。规则配置页须明确提示“同邮箱不代表同一 SkillHub 账号”，并在消费结果中展示实际获授角色的账号与外部来源，防止管理员误认授权对象。角色授予接入当前公开 OAuth 的账号创建事务，不改变统一身份核心已有的关联或准入决策。
+
+建议独立表保存 `id`、`provider_code`、`normalized_email`、`role_id`、`status`（`ACTIVE`/`DISABLED`/`CONSUMED`）、`matched_subject`、`granted_user_id`、`granted_at`、`created_by`、`updated_by`、时间戳和并发版本。最多允许一条同一来源与规范化邮箱的 ACTIVE 规则；消费记录保留用于审计。首次绑定、角色写入和规则消费必须原子完成，并通过身份唯一约束及规则条件更新处理并发首次登录。若规则在登录时被停用，以事务中读取并确认的当前状态为准。
+
+当前 `PENDING_APPROVAL` 没有实际策略来源。本变更不定义待审批账号的延迟自动授予；未来启用该策略时，需要单独确定审批后的规则消费时点，不能把 PENDING 账号当作已获角色的成功登录。
+
+### 4. 部署参数只初始化一次
+
+首次部署时，部署参数为缺失的 `auth.local` 设置行提供初始值，并可为新安装提供初始外部角色规则。初始化结果及“已初始化”状态必须持久化。此后即使规则表被清空或某设置被后台修改，重启也不能重新灌入旧部署值。新版本新增的设置键可独立补入默认值，但不得覆盖旧键。初始化角色规则必须验证来源、邮箱格式、目标角色与重复项；错误不能静默退化为超管授权。
+
+`BOOTSTRAP_ADMIN_*` 当前用于本地密码管理员，仍按现有独立机制处理；本变更不把它迁入数据库，也不改变其启动行为。OAuth 客户端密钥、数据库凭证等继续放部署秘密配置。新安装若同时关闭本地登录，部署方必须确保外部来源、普通准入策略和初始角色规则相互匹配；规则不会绕过准入。
+
+## Alternatives considered
+
+- **管理员规则绕过普通准入**：拒绝。会改变现有每次登录先检查准入的行为，并引入长期准入例外。
+- **每次登录按规则同步角色**：拒绝。会覆盖或重新授予人工调整过的权限，也与“停用只阻止新授权”冲突。
+- **所有数据放 `system_setting` JSON**：拒绝。逐人规则需要独立生命周期、唯一性、并发消费和审计。
+- **关闭本地登录时强制阻止可能锁定的配置**：拒绝。外部提供方是否实际可用无法可靠静态判断；页面明确提示后允许部署方决定。

+## Why
+
+Issue #923 需要让采用外部身份认证的部署方分别关闭本地密码登录和本地自行注册。现有本地入口始终可见，后端也没有对应开关；仅依赖部署参数无法让管理员在后台维护运行设置。纯外部登录部署还需要一种明确指定外部账号首次进入 SkillHub 时所获平台角色的方式，同时保留现有 OAuth 准入优先级。
+
+## What Changes
+
+- 增加统一的后台“系统配置”页面。两个本地认证开关存入 `system_setting`；外部账号首次角色授权规则存入独立表。只有超级管理员可修改，操作进入现有审计日志。
+- 本地密码登录和本地自行注册分别控制，默认保持现状。关闭登录时，前后端停止新的密码认证和密码管理操作；已建立的会话按原有效期处理。关闭注册只停止本地自行注册，不影响已有账号的密码登录或外部身份首次进入。
+- 外部身份仍先经过现有普通准入策略。仅当准入允许且外部身份首次创建 ACTIVE 账号时，匹配来源与已验证邮箱，授予规则指定的一个平台角色。规则不覆盖准入拒绝，也不在已有账号下次登录时补授权。
+- 部署参数仅用于首次初始化缺失的运行设置和空库的初始外部角色规则；初始化状态持久化。之后数据库和后台页面是权威来源，删除规则后重启不得复活。紧急恢复使用受控数据库操作，不增加专用服务器命令。
+- 关闭本地登录时展示管理入口锁定风险，但允许超级管理员继续保存。外部身份提供方凭证等秘密继续由部署配置管理，不进入 `system_setting`。
+
+## Capabilities
+
+### New Capabilities
+
+- `system-auth-settings`：数据库持久化的本地认证开关、后台配置、公开能力展示和一次性初始化。
+- `initial-external-role-grants`：外部身份首次创建账号时的一次性平台角色授予规则。
+
+## Impact
+
+- 后端认证、OAuth 首次账号创建、数据库迁移、审计和后台管理 API。
+- 登录、注册、重置密码、个人设置和后台系统配置页面。
+- 部署参数仅增加初始化输入；现有准入策略、已建会话和人工用户角色管理语义保持不变。
+

+## Purpose
+
+允许部署方为外部身份首次创建的 SkillHub 账号预设一个平台角色，同时保留普通准入和人工角色管理的现有行为。
+
+## ADDED Requirements
+
+### Requirement: REQ-IERG-01 外部角色规则 SHALL 只在准入允许后的首次账号创建时生效
+
+系统 SHALL 先执行现有普通准入判断。只有 `ALLOW` 且 `(provider_code, subject)` 尚无 SkillHub 账号时，才可匹配 ACTIVE 规则。规则 SHALL 要求来源和规范化的已验证邮箱一致，并授予所选的一个现有平台角色。授权写入 SHALL 在登录主体和会话建立前完成。
+
+#### Scenario: 新账号匹配规则
+- **WHEN** 外部身份通过普通准入，来源和已验证邮箱命中 ACTIVE 规则，且身份首次创建账号
+- **THEN** 系统创建 ACTIVE 账号、身份绑定和角色绑定，并消费规则
+- **AND** 首次登录主体包含该平台角色
+
+#### Scenario: 普通准入拒绝
+- **WHEN** 外部身份虽命中管理员规则，但普通准入结果为 `DENY`
+- **THEN** 系统拒绝登录，不创建账号、不消费规则、不授予角色
+
+#### Scenario: 邮箱不可信
+- **WHEN** 外部来源未提供邮箱，或邮箱未验证
+- **THEN** 系统不通过邮箱规则自动授予角色
+
+#### Scenario: 已有普通账号后来出现规则
+- **WHEN** 已有身份绑定的普通账号再次登录，后台才新增对应规则
+- **THEN** 登录不消费该规则，也不自动改变已有角色
+- **AND** 管理员可通过现有用户管理功能人工授权
+
+#### Scenario: 同邮箱的本地账号与外部账号
+- **WHEN** 本地账号已使用某邮箱，另一外部身份首次进入且以同一已验证邮箱命中规则
+- **THEN** 系统按现有身份绑定逻辑创建独立的外部账号，并把角色授予该新账号
+- **AND** 不把角色授予同邮箱的本地账号，也不自动合并两个账号
+
+### Requirement: REQ-IERG-02 规则消费和角色授予 SHALL 原子且一次性
+
+系统 SHALL 在同一数据库事务内完成首次身份绑定、角色写入和规则消费。消费记录 SHALL 绑定实际来源、subject 和用户，防止邮箱再次归属另一人后重复授权。并发首次登录 SHALL 最多授予同一用户一次，不得把规则授予两个账号。
+
+#### Scenario: 并发首次登录
+- **WHEN** 同一外部身份几乎同时发起两次首次登录
+- **THEN** 最终只有一个账号和身份绑定，规则只消费一次，角色结果一致
+
+#### Scenario: 规则授予后停用
+- **WHEN** 规则已经授予角色，管理员随后停用或删除该规则
+- **THEN** 已有角色保持，已有账号以后登录仍按普通准入策略判断
+- **AND** 规则不能再次授予另一外部身份
+
+#### Scenario: 人工修改角色
+- **WHEN** 管理员在用户管理页面修改已获角色的账号
+- **THEN** 后续登录不因旧规则重新授予或覆盖角色
+
+### Requirement: REQ-IERG-03 规则管理 SHALL 限定超管并保留审计
+
+系统 SHALL 在统一“系统配置”页面提供规则增改、停用和消费结果查看。只允许超级管理员管理规则。角色只能从已存在的平台角色中选择，每条规则只指定一个角色。规则变更和自动授予 SHALL 记录审计，不得泄漏 OAuth 凭证。
+
+规则页面 SHALL 告知管理员“同邮箱不代表同一 SkillHub 账号”，消费结果 SHALL 展示实际获授角色的账号和外部来源。
+
+#### Scenario: 非超管试图配置超级管理员规则
+- **WHEN** 非超级管理员直接调用规则写入 API
+- **THEN** 系统拒绝请求，且规则和角色绑定均不改变
+
+#### Scenario: 重复有效规则
+- **WHEN** 同一外部来源和规范化邮箱已有 ACTIVE 规则
+- **THEN** 系统拒绝第二条同时生效的规则
+
+### Requirement: REQ-IERG-04 部署初始化 SHALL 一次性且不复活已删除规则
+
+新安装可用部署参数提供初始角色规则，但系统 SHALL 持久化初始化状态。后续由数据库和后台页面管理；表为空不构成再次初始化条件。紧急恢复可由受控数据库操作完成。
+
+#### Scenario: 管理员删除全部规则后重启
+- **WHEN** 初始化已完成，管理员删除或停用所有规则，而旧部署参数仍存在
+- **THEN** 重启不重新创建这些规则
+
+#### Scenario: 初始规则不符合普通准入
+- **WHEN** 初始管理员规则指向的身份被现有普通准入策略拒绝
+- **THEN** 规则不绕过准入，也不完成授权
+- **AND** 部署方需调整普通准入或规则配置

+## Purpose
+
+让部署方分别控制本地密码登录和自行注册，并在统一后台页面管理非秘密运行设置。
+
+## ADDED Requirements
+
+### Requirement: REQ-SAS-01 两个本地认证开关 SHALL 独立且默认保持现状
+
+系统 SHALL 提供密码登录与本地自行注册两个独立布尔开关。未配置时两者 SHALL 默认为开启。关闭任一开关 SHALL 同时作用于前端入口和对应后端请求。
+
+#### Scenario: 只关闭自行注册
+- **WHEN** `selfRegistrationEnabled=false` 且 `passwordLoginEnabled=true`
+- **THEN** 本地注册页面和 API 不可用
+- **AND** 现有本地账号仍可登录和使用密码管理功能
+- **AND** 外部身份首次进入仍按现有准入策略处理
+
+#### Scenario: 只关闭密码登录
+- **WHEN** `passwordLoginEnabled=false` 且 `selfRegistrationEnabled=true`
+- **THEN** 密码登录、direct 本地认证、密码重置和密码修改均不可用
+- **AND** 本地注册也暂时不可用，因为现有注册成功会直接建立会话
+- **AND** 页面不展示上述入口，直接访问页面得到明确提示
+- **AND** 注册开关仍保留自身设置值，重新开启密码登录后恢复其原有作用
+
+#### Scenario: 已有会话
+- **WHEN** 管理员关闭密码登录，而某本地账号已经建立会话
+- **THEN** 该会话按现有有效期和失效机制处理
+- **AND** 后续新密码认证被拒绝
+
+### Requirement: REQ-SAS-02 系统设置 SHALL 由数据库管理并受权限及审计保护
+
+系统 SHALL 将注册过的非秘密运行设置持久化在 `system_setting`，只允许超级管理员通过后台修改，使用版本条件防止并发覆盖，并记录现有审计日志。公开认证能力接口 SHALL 只暴露登录页所需的安全字段。
+
+#### Scenario: 并发修改
+- **WHEN** 两名管理员基于同一旧版本分别提交修改
+- **THEN** 只有先成功提交的修改生效，另一请求收到可识别的版本冲突
+
+#### Scenario: 读取设置失败
+- **WHEN** 新认证请求无法读取数据库中的本地认证设置
+- **THEN** 请求失败并给出服务不可用结果
+- **AND** 不使用默认开启值放行认证
+
+#### Scenario: 非超级管理员修改
+- **WHEN** 普通用户或非超管管理员直接调用设置写入 API
+- **THEN** 系统拒绝请求且不修改设置
+
+### Requirement: REQ-SAS-03 部署参数 SHALL 只初始化缺失的设置
+
+新安装首次初始化时 SHALL 使用部署参数或代码默认值填充缺失设置，并持久化初始化状态。已经持久化的设置 SHALL 不被后续部署参数或重启覆盖。外部服务秘密不得存入设置表。
+
+#### Scenario: 后台关闭登录后重启
+- **WHEN** 后台已持久化 `passwordLoginEnabled=false`，部署参数仍写着开启
+- **THEN** 重启后数据库设置仍为关闭
+
+#### Scenario: 新版本增加设置键
+- **WHEN** 升级版本新增注册过的设置键
+- **THEN** 系统只为新键补入默认值，不修改既有键
+
+### Requirement: REQ-SAS-04 关闭本地登录 SHALL 展示风险但不阻止保存
+
+后台页面 SHALL 告知超级管理员：外部登录不可用时可能失去管理入口。服务端 SHALL 接受其关闭本地登录的合法请求，而不根据外部账号是否已绑定进行硬拦截。
+
+#### Scenario: 没有已绑定的外部超管
+- **WHEN** 超级管理员确认关闭本地密码登录
+- **THEN** 页面展示管理入口风险，保存仍可完成
+- **AND** 不误称已经验证外部身份提供方可用

+- [x] 在 OAuth 普通准入允许后的首次 ACTIVE 账号创建事务中匹配并消费角色规则，首次主体包含新角色。
+- [ ] 在统一身份核心的 `LEGACY`、`SHADOW`、`ACTIVE` 模式下核对公开 OAuth 接入点；保持旧身份绑定写入权威与同邮箱不自动合并的现有行为。
+- [ ] 保持已有账号、准入拒绝、未验证邮箱、停用规则、并发首次登录和人工角色修改的既定行为。
+
+## 3. API 与 Web
+
+- [x] 增加超级管理员可读写的系统设置与规则 API，增加登录页所需的公开认证能力投影。
+- [x] 建立统一“系统配置”页面，显示两开关、角色规则、消费结果及关闭本地登录的风险提示。
+- [x] 调整登录、注册、重置密码和个人设置入口；直接访问已关闭页面时显示明确结果。
+- [x] 更新 OpenAPI、部署说明和用户操作说明。
+
+## 4. 验收
+
+- [ ] 验证两个开关的四种组合、直接 API 绕过尝试、已有会话、DB 故障与多实例设置可见性。
+- [ ] 验证首次登录授权、准入优先、已有账号不补授权、同邮箱独立账号、邮箱验证、规则停用、角色人工修改和并发首次登录。
+- [ ] 验证一次性部署初始化、角色规则删除后重启、非超管越权、审计记录和浏览器页面流程。
