 ## Decision
 
-`@deepseek-ai/dsh-session-telemetry-otel` exposes three uppercase `mode` values:
+`@deepseek-ai/dsh-session-telemetry-otel` exposes the string-valued `TelemetryMode` enum to TypeScript callers and accepts the same three uppercase `mode` values in serialized configuration:
 
 - `FULL` is the default and preserves immediate delivery to the configured OTel pipeline.
 - `FEEDBACK_ONLY` reads the canonical session log when `feedback/record` is appended and hands over the unreleased prefix through that exact event. Records appended after that boundary remain local until another feedback event.

+`@deepseek-ai/dsh-session-telemetry-otel` 向 TypeScript 调用方公开以字符串为值的 `TelemetryMode` 枚举，并在序列化配置中接受相同的三个大写 `mode` 值：
 
 - `FULL` 是默认值，保留向已配置 OTel 流水线的即时投递。
 - `FEEDBACK_ONLY` 在追加 `feedback/record` 时读取权威会话日志，并交接截至该事件的未释放前缀。该边界后追加的记录会留在本地，直到另一个反馈事件。
