Claude Code v2.1.223 ·

CCR stream-event flush interval is validated and clamped

A remotely tuned batching interval is now range-checked so a bad value cannot break event flushing.

What

The flush interval for CCR client stream events is now sanity-checked instead of being used as supplied.

Details
  • The value comes from the remote config tengu_ccr_stream_event_flush_ms, falling back to a built-in default.
  • String values are coerced to numbers.
  • Non-finite values produce a warning and fall back to the default.
  • The final value is clamped to 0 to 60000 ms.

CCRClient: non-finite streamEventFlushIntervalMs

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
