  • config_root/instance-settings.json 为第五层：default > .env > 进程env > CLI > instance-settings
  • LoadForServe 统一 serve/check/explain 入口；老 Load 行为不变
  • 定位字段（env）自覆盖失败关闭；SETTINGS_MODE=ignore 跳层恢复
  • 反射类型化应用（含 duration 两种形态），未知字段/类型不匹配失败关闭；宽松文件权限拒绝；缺省键=继承
  • 8 项单测 + e2e 冒烟（覆盖生效/ignore 回退）

- <config_root>/instance-settings.json is the final config layer:
  default > env-file(s) > process-env > cli > instance-settings
- LoadForServe wires the CLI mutation hook BEFORE instance settings;
  serve/check/explain all use it; plain Load keeps legacy behavior
- bootstrap denylist (env) fails closed (no self-locating file loop);
  SETTINGS_MODE=ignore skips the layer as the recovery path
- reflection-based typed application: string/int/bool/duration(string or
  seconds)/string-array; unknown fields and type mismatches fail closed
- group/world-writable settings file rejected; absent key = inherit
- sources table gains the instance-settings layer; e2e smoke verified
  (override applies; ignore-mode reverts to default)
