- Phase 0: AGENTS.md cleanup (dedup quotes, renumber sections, merge qmd)
- Phase 1: typed relations (manage-relations.py, graph-search.py, check-staleness.py, detect-conflicts.py)
- Phase 2: frontmatter validator, weekly lint, knowledge promotion, git hooks
- Fix .gitignore to track tools/ and .githooks/
- Fix git remote URL (remove plaintext token)
- New wiki pages: 504 pages, 34 raw sources
