Adrian PerezandClaude Opus 4.7 a2e287144b test(mcp): Casa del Sol — full house built end-to-end via MCP 
Design and live-built a 3-bed 2-bath single-story house with pool and
privacy-screened perimeter ("Casa del Sol") using only @pascal-app/mcp
tools. Exercises every mutation tool in a realistic scenario.

- DESIGN.md: blueprint (lot 20x15, building 12x8, 7 interior zones,
  pool 5x3, 5 privacy fence segments)
- build.ts: MCP client orchestrator
- scene.json: full exported scene (26.7 KB)
- BUILD_REPORT.md: per-step status + final totals

Final scene: 39 nodes pre-duplicate (1 site, 1 building, 1 level,
9 walls, 9 zones, 6 doors, 6 windows, 5 fences, 1 slab), 76 nodes
post-duplicate_level, valid=true, errors=0.

Surfaced the documented StreamableHTTP single-session limitation:
the HTTP server at :3917 rejected the SDK client's initialize with
"Server already initialized" because the previous T3 session consumed
the transport's one-shot session slot. Build fell back to an in-memory
transport exercising the identical tool surface. Fix tracked for v0.2.

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.
