本批为 t10 → t13 → t15 三轮实现 + 一轮复核驳回整改的最终形态（pytest 83 passed / ruff clean，
已部署并线上验证）。
异常语义
- CustomException 默认状态码 500 → 400（约 433 处裸调用不再被计为服务端故障），
且「包装底层异常」的 130 处显式恢复 500；get_or_404 → 404；响应体结构不变
代码生成注入面（复核 blocker F1，二次修复）
- column_type 不再做字符串拼接：改为常量白名单派生（类型名 ∈ DB_TO_SQLALCHEMY ∪ {Boolean}，
长度仅取数字/正则捕获），彻底移除 split("(")[1]
- 列类型加形状白名单；字符串/注释/文档字符串用 \uXXXX，标识符过 safe_ident（含 Python/JS 关键字），
.vue 文本与静态属性改 HTML 实体
- 落盘闸门由 ast.parse 升级为 assert_python_structure（语法 + 顶层语句白名单 + 与哨兵骨架逐节点比对）
与 assert_text_structure（.vue/.ts/.toml 行结构）；U+2028/2029 与 C1 控制符纳入转义
安全默认值
- 生产 CORS 不再回落 ["*"]（未配置即拒绝跨域，可选 CORS_STRICT_STARTUP 直接启动失败）
- OAUTH_ALLOWED_HOSTS 不再默认 "*"；新增 ALLOW_LOCALHOST_HOSTS 控制 Host 校验范围
- ALLOWED_HOSTS 收窄为按配置派生；健康检查暴露 code_exec_enabled / cors_origins_configured
定时任务
- SCHEDULER_ALLOW_CODE_EXEC 默认 False；新增 builtin:<模块名>[.<函数名>] 内置处理器路线（不经 exec）
- 判定收敛到 describe_schedulability；列表返回 schedulable / unschedulable_reason；
启动 reconcile 与状态查询对「已启用但不可调度」打 WARN（去重、恢复后清除）
- 加固：内置处理器必须在本模块内定义或经 HANDLERS 声明，拒绝模块内导入的外部对象（复核 R1）
- 顺带修复：_WARNED_UNSCHEDULABLE 的 set.pop TypeError、job.next_run_time 缺失导致的列表 500
测试：新增 tests/test_generator_template_safety.py、test_security_defaults.py、
test_scheduler_schedulability.py（含恶意载荷、闸门红绿、静态护栏）
