 ## 阶段 A 离线闭环
 
-`POST /api/phase-a/accounts` 只接受 OS Keyring/Secret Manager 的引用标识，不接受秘密值；账号的 `profile_id` 全局唯一。`POST /api/phase-a/runtimes` 通过部分唯一索引保证一个账号和一个运行时都只有一条活动绑定。
+`POST /api/phase-a/accounts` 接受 `{id, platform, platform_account_key, authorization_kind, credential_reference}`，只允许 OS Keyring/Secret Manager 引用，不接受秘密值；新账号默认 `paused`，`(platform, platform_account_key)` 全局唯一。`GET /api/phase-a/accounts[/:id]` 不返回引用 key；pause/revoke 会递增账号版本并将 queued 任务置为 `policy_hold`，只有具备 binding 和 healthy 出口的未撤销账号才能 resume。账号与浏览器环境通过一对一 `environment_binding` 关联，出口可复用；运行实例保留历史，并以 binding 和外部 runtime id 的部分唯一索引限制活动实例。
 
 草稿经 `POST /api/phase-a/confirmations` 显式确认后才可投递到 `/api/phase-a/tasks`。任务由幂等键去重；`POST /api/phase-a/mock/execute` 使用 `FOR UPDATE SKIP LOCKED` 领取一分钟租约，执行前统一核对账号、草稿和确认版本。缺少确认或版本不一致会进入 `needs_confirmation`，暂停账号或 Mock 策略结果会进入 `policy_hold`，不确定结果与过期租约进入 `needs_confirmation`；这些状态都不会自动重试。`GET /api/phase-a/audit` 只导出账号、确认版本、尝试和结果等非秘密证据。
 
-启动时控制面在事务和 advisory lock 下应用前向迁移 `internal/phasea/migrations/001_phase_a.sql`。本迁移只新建表、索引、约束和追加式审计触发器，不删除或改写现有数据；回滚需停服务后人工删除阶段 A 新表，本阶段不提供自动破坏性回滚。
+启动时控制面先应用 Phase A v1，再由 Hub runner 顺序应用 v2、v3；每一步都在事务和 advisory lock 下前向执行。v3 保留旧表、列和历史记录，旧账号回填为 `platform=mock` 并暂停，仅账号 ID 与环境 alias 相同的记录自动建立 binding；其余记录等待显式绑定。本阶段不提供破坏性自动回滚。
