## Known discrepancies with DESIGN.md

- Garden zone polygon equals the full site polygon (20x15) — per design brief §Garden zone we set it to the site polygon and rely on the building zones overlapping visually, rather than subtracting the building footprint.
- Build fell back to in-memory MCP transport. The HTTP server at http://localhost:3917/mcp rejected the SDK client's initialize with "Server already initialized" — the server uses the SDK's single-session StreamableHTTPServerTransport which only accepts one `initialize` POST per process lifetime. The tool surface exercised is identical; only the wire transport differs.
