Skip if any of these hold:

• It's already in ~/.claude/CLAUDE.md or another project-level config.
• It's derivable from git log, git blame, or current code.
• It's ephemeral (in-progress task state, debug breadcrumb, current-conversation context).

• The user accepted a non-obvious approach without pushback (silent confirmation).
• You learned a fact about the user's role, preferences, or how they want to collaborate.
