```

## From README

/understand-domain Extracts business domain knowledge — domains, business flows, and process steps — from a codebase and produces an interactive horizontal flow graph in the dashboard. How It Works If a knowledge graph already exists (.ua/knowledge-graph.json, or the legacy .understand-anything/knowledge-graph.json when that directory is present), derives domain knowledge from it (cheap, no file scanning) If no knowledge graph exists, performs a lightweight scan: file tree + entry point detection + sampled files Use --full flag to force a fresh scan even if a knowledge graph exists Instructions Phase 0: Resolve PROJECTROOT Set PROJECTROOT to the current working directory. Worktree redirect. If PROJECTROOT is inside a git worktree (not the main checkout), redirect output to the main repository root.
