What
Compaction is when Claude Code summarizes a long conversation to free up room. It now keeps a record of which versions of artifacts had been read before the summary, and one path clears that record. Several smaller changes came with it:
Error results now pass along the underlying API error.
The exit status can now report ran_nothing.
Usage reporting gains a few new fields.
Why
These are small changes to reporting and to the messages Claude Code passes between its parts.
