Durable technical knowledge for Se7en.

This is not a diary and not raw chat history. It is the curated knowledge base: project notes, patterns, mistakes, concepts, and maintainer observations that should survive across sessions.

projects/      repo-specific field notes
patterns/      reusable engineering patterns
mistakes/      mistakes and prevention notes
concepts/      technical concept explanations
maintainers/   maintainer and project-community preferences

After meaningful technical work, ask:

• What did I learn that should be reusable?
• Which project note should be updated?
• Did I hit a mistake that should not repeat?
• Is there a pattern worth naming?

If yes, write it here.

Every task should run a writeback review before completion. See patterns/agent-writeback-review.md.
