Remote sessions hold back some transcript entries until a compaction summary is ready

In a remote session, Claude Code uploads the session's events, its running record, as it goes. Compaction is when Claude Code shrinks a long conversation by replacing older parts with a summary. Some entries are now held back until that summary arrives.

While entries are held back:

• They count toward the number of events still waiting to be uploaded.
• No more internal events are accepted for upload.
• If the session closes first, they are dropped or counted, and the close also stops work still in progress.
