DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

File History Cleanup on Session Expiry

What: New cleanup function removes expired file history backup directories based on the configured retention period.

Details:

  • Function yr5() at line 442733 removes backup directories older than retention threshold
  • Respects cleanupPeriodDays setting from configuration
  • Returns statistics: { messages: count, errors: count }
  • Integrated into session cleanup routine at rQQ() at line 442760
  • Empty directories are removed after cleanup
Evidence

yr5() at line 442733, integration at line 442760 (previously uQQ())

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
