189189If you set `CLAUDE_ENABLE_BYTE_WATCHDOG_BEDROCK=1`, the byte-level watchdog replaces the body idle timeout on Bedrock rather than running alongside it. `CLAUDE_STREAM_IDLE_TIMEOUT_MS` then also governs how long a Bedrock stream may stay silent before Claude Code treats the connection as dead, within the limits listed below. Arriving bytes still don't reset the event-level watchdog on Bedrock. With debug logging on, each Bedrock stream then logs a debug message that starts with `wire-heartbeat: _chunkTimes absent`.
No line in this hunk matches that.
