Under the hood, is this simply checkpointing the files in the claude target folder or are you also checkpointing the claude context? One of my biggest pain points is after a few compactions/edits to claude.md and all of a sudden Claude has made a few mistakes and all the context window cruft of fixes it attempted and reverted actually seem to confuse it further and it would be nice to reset to a known happy place code & contextually and retry from there.
