Plan to apply Graph-CAD's hierarchical graph intermediate representation approach to archilang's Tier 3 (LLM integration). Defines a 4-phase strategy: graph schema, graph-to-yaml engine, LLM prompt design, and evaluation framework. https://claude.ai/code/session_017rppwCngGYq9Q2C9Hqypbm
Add intermediate graph representation for LLM-based floor plan generation, inspired by Graph-CAD (ICLR 2026). The pipeline converts a FloorplanGraph JSON (rooms, connections, constraints) into valid archilang YAML. New modules: - src/graph/types.ts: FloorplanGraph schema (zones, rooms, connections, constraints) - src/graph/room-sizer.ts: tatami → grid size conversion - src/graph/zone-placer.ts: zone ordering with cross-band connection awareness - src/graph/grid-packer.ts: 2-row constraint-based rectangle packing - src/graph/opening-placer.ts: connection edges → openings/equipment specs - src/graph/graph-to-yaml.ts: main conversion pipeline + YAML serializer CLI: - `generate` command: graph.json → YAML → validate → render - `generate --prompt`: outputs LLM prompt template for graph generation - `generate --render`: also produces SVG output Tests: 9 new tests (all 188 pass) https://claude.ai/code/session_017rppwCngGYq9Q2C9Hqypbm
