 | ACP `agentOptions` root export | The helper has only same-file and ACP-test consumers; the sole outside-package production consumer mounts the plugin namespace. | Keep `name`, `inject`, `Config`, `AcpConfig`, and `apply`; make `agentOptions` source-private and test it through bridge behavior. |
 | `providerWording` and `completedTurnPrefix` root exports | Each has one same-package production caller; only the balanced-prefix helper has a same-package white-box test. | Make them source-private and test provider behavior. |
-| `depthOf`, `SubagentDepthError`, `SENSITIVE_ENV_PATTERN`, `waitForExit`, and `exitsWithin` root exports | Production subagent backends consume the in-process runner and subprocess construction/disposal helpers, not these enforcement/test internals. | Keep depth/environment/exit behavior but make the helpers and error/regex source-private; test through spawn and disposal. |
+| `depthOf`, `SubagentDepthError`, `waitForExit`, and `exitsWithin` root exports | Production subagent backends consume the in-process runner and subprocess construction/disposal helpers, not these enforcement/test internals. `SENSITIVE_ENV_PATTERN` is excluded because the SDK helper applies it to caller-supplied environments. | Keep depth and exit behavior but make the remaining helpers and error source-private; test through spawn and disposal. Keep the shared credential pattern public. |
 | `PersistenceCoordinator.inits`, backend `inits` accessors, `seedCoversPrefix`, and `assertSerializable` | The accessors exist for white-box tests; `seedCoversPrefix` has no outside production importer; `assertSerializable` has no production caller and duplicates the coordinator append boundary's lossless snapshot. | Observe initialization through `session/flush`, make `seedCoversPrefix` source-private, and delete `assertSerializable`. Keep both backends, `SessionHeader`, and SQLite's version contract. |
 | `LlmError.status` and replay status | Adapters/replay populate it, but production branches on stable error code/message and never reads raw status. | Remove the unread field and replay plumbing while preserving error classification. |
 | `BlockAssembler.push()` return value | Both production callers ignore the returned completed block. | Return `void`; keep the deliberately public `blocks()`/`message()` contract. |

 | ACP 的 `agentOptions` 根导出 | 该辅助函数只有同文件和 ACP 测试消费方；唯一的包外生产消费方挂载的是插件命名空间。 | 保留 `name`、`inject`、`Config`、`AcpConfig` 和 `apply`；将 `agentOptions` 改为源码私有，通过桥接层行为测试。 |
 | `providerWording` 与 `completedTurnPrefix` 根导出 | 各有一个同包生产调用者；只有 balanced-prefix 辅助函数有一个同包白盒测试。 | 改为源码私有，测试提供方行为。 |

 | `LlmError.status` 与回放 status | 适配器/回放填充它，但生产分支基于稳定的错误码/消息判断，从不读取原始 status。 | 移除未读字段和回放管道，保留错误分类。 |
