What
When the daemon creates a background session, it writes a host tombstone file or record. The daemon is a Claude Code process that runs sessions in the background, and the tombstone is a marker it leaves for each session. That record used to be written empty. It now holds content taken from the environment the session was started with.
Why
The tombstone now keeps information about how the session was started.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The finding does not say what is written from the environment or what reads the tombstone.
Anthropic's release notes agree
