Install harness-engineering doctrine into a repository — short root AGENTS.md, docs/ taxonomy (plans, ADRs, solutions), verification rules, and project-scoped Claude Code plugins. Works on empty repos (greenfield scaffold), existing repos (survey + upgrade), and ports of existing systems. Distinct from marvin:scaffold (which installs deps and configs); distinct from cc-lab:cc-lab-diagnose (which observes but doesn't change anything). Triggers: harness up, harness this repo, set up AGENTS.md, agent doctrine, make this repo agent-ready, init harness, scaffold agent context.
