What probably matters to you Section of the release
What
The background worker that syncs directory contents now starts only when a decision helper allows it, and CLAUDE_CODE_DISABLE_DIR_SYNC feeds that decision alongside the entrypoint being used. When it is skipped for that reason, a telemetry line records it.
Evidence
dir_sync_worker_disabled
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
