What

Claude Code has added two internal helpers:

  • Spare-session state: records whether a spare launch is parked, claiming, claimed or failed, and when it was parked.
  • Block removal: takes a block out of content that mixes plain text and blocks, finding it by its id and tidying the spacing around it.
Why

These are internal building blocks. The finding shows nothing a user sees or does differently because of them.
