tooling

I built Karpathy's LLM wiki pattern into Command, my Claude Code operator: 134 provenance-tagged pages, a grep gate that blocks fabricated quotes, a nightly digest pipeline that was reset after a cheap model wrote a wrong verdict into it, and a human-gated publish wall.

The cleanupPeriodDays default is 30 days, so Claude Code deletes session transcripts older than that at startup. Set it higher in ~/.claude/settings.json to stop the deletions. What the setting covers, what was already gone on my machine, and why raising it can't recover the past.
