Unclear The finding does not say what directory-sync 'chained' mode actually does differently, or who it is intended for.

What

The engine that keeps directories in sync now has a chained mode. It stays off unless an environment variable called CLAUDE_CODE_DIR_SYNC_CHAIN is set to exactly true.

Why

Since this isn't documented and requires manually setting an environment variable, most users won't encounter it. It appears to be an internal or experimental switch rather than a supported option.
