Under the hood
The 'summarized all' compaction telemetry event now fires under broader conditions
What
The internal telemetry event compact_reactive_summarized_all, recorded when Claude Code compacts (trims) a long conversation, now fires whenever the split kind isn't 'round' and either the mode is 'auto' or some messages were truncated from the start of the conversation. Previously it only fired when the split kind was exactly 'summarize_all'.
Why
This means the event now gets logged in more situations than before, giving a broader picture of when full-conversation summarization happens during compaction, though it is purely a measurement change with no visible effect for users.
