costcodev ab9b62e9b3 feat(BIZ-129): 方案 C 用户系统 DB 层 + 业务层(BIZ-127 #1/#2/#5/#6/#8 对齐)
- auth_db.py: users/sessions/password_reset_tokens/operation_logs 4 表 + migrate_legacy_schema 增量升级
- auth.py: hash_password(rounds=12) + create_session(token_hash=sha256) + authenticate(锁定→清零) + cleanup_op_logs(90d)
- 业务层已就绪,未完成:auth_api 蓝图 / require_auth 装饰器 / 限流 / pytest / 前端 3 页

用户系统数据库模块 — BIZ-129 方案 C
表:
- users 用户账号(含多用户预留字段 / 登录失败锁定字段)
- sessions 服务端 session(存 token_hash,不存明文 cookie 值)
- password_reset_tokens 找回密码一次性 token
- operation_logs 操作日志(90 天保留)
约束对齐 — BIZ-127 架构侧清单:
#2 sessions.token_hash = sha256(cookie_value).hexdigest()
#5 users.tenant_id / users.status(数据层预留,UI 不写)
#6 users.failed_attempts / users.locked_until(登录失败锁定)
升级路径:旧装已存在的 `users` / `sessions` 表会被 `migrate_legacy_schema()` 增量升级,
不会丢数据。新装直接走 CREATE TABLE。

# 4. rename token_hash_temp → token_hash
