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.

# Casa del Sol — design brief
A single-story 3-bedroom, 2-bathroom house with a swimming pool and a privacy-screened perimeter, built entirely via `@pascal-app/mcp` HTTP tools against a fresh scene.
## Lot
- Site polygon: 20 × 15 m rectangle centred at origin → corners (10, 7.5) to (10, 7.5).
- Origin axes: +x = east, +z = south (core convention; floor plane is xz).
## Building envelope
- Footprint: 12 × 8 m, centred west-of-origin at about (2, 0).
- Wall thickness: 0.2 m. Wall height: 2.7 m.
- Floor elevation: 0. Single storey.
## Interior rooms (zones)
Origin for interior: building SW corner at (8, 4). All rooms span the 8 m building depth somehow.
| Room | Footprint (x × z) | Polygon corners |
|-----------------|----------------------|-----------------------------------------|
| Living / dining | 7 × 4 | (8, 0) (1, 0) (1, 4) (8, 4) |
| Kitchen | 5 × 4 | (1, 0) ( 4, 0) ( 4, 4) (1, 4) |
| Bedroom 2 | 4 × 4 | (8, 4) (4, 4) (4, 0) (8, 0) |
| Hallway | 3 × 1 | (4, 2) (1, 2) (1, 1) (4, 1) |
| Bathroom 2 | 3 × 2 | (4, 4) (1, 4) (1, 2) (4, 2) |
| Bathroom 1 | 3 × 1 | (4, 1) (1, 1) (1, 0) (4, 0) |
| Master bedroom | 5 × 4 | (1, 4) ( 4, 4) ( 4, 0) (1, 0) |
## Walls (perimeter + partitions, one wall per edge)
**Perimeter (4):**
1. South outer: (8, 4) → (4, 4)
2. North outer: (8, 4) → (4, 4)
3. West outer: (8, 4) → (8, 4)
4. East outer: (4, 4) → (4, 4)
**Interior (partitions):**
5. Living/Kitchen split: (1, 0) → (1, 4)
6. North bedrooms split: (1, 4) → (1, 0)
7. Bedroom 2 east wall: (4, 4) → (4, 0)
8. Hallway north edge: (4, 1) → (1, 1)
9. Hallway south edge: (4, 2) → (1, 2)
## Openings (doors + windows)
All positions are normalised 0..1 along the wall (start → end).
| Kind | Wall | Pos | Width | Height | Purpose |
|---------|----------------------------------------|-----|-------|--------|----------------------|
| door | 1 (south outer) | 0.20| 0.9 | 2.1 | Front entrance |
| door | 1 (south outer) | 0.75| 2.2 | 2.1 | Sliding glass to pool|
| door | 2 (north outer) | 0.65| 0.9 | 2.1 | Kitchen back door |
| door | 6 (N-bedrooms split, middle) | 0.30| 0.8 | 2.1 | Master bedroom door |
| door | 7 (Bedroom 2 east wall) | 0.50| 0.8 | 2.1 | Bedroom 2 door |
| door | 9 (Hallway south edge) | 0.50| 0.7 | 2.0 | Bathroom 2 door |
| window | 1 (south outer, living) | 0.30| 2.0 | 1.4 | Living picture window|
| window | 1 (south outer, living) | 0.45| 1.4 | 1.4 | Living window 2 |
| window | 3 (west outer) | 0.25| 1.0 | 1.1 | Kitchen window |
| window | 4 (east outer) | 0.25| 1.4 | 1.4 | Master window |
| window | 4 (east outer) | 0.75| 1.4 | 1.4 | Bedroom 2 window |
| window | 2 (north outer, bathroom 2) | 0.30| 0.8 | 0.6 | Bathroom 2 high |
(Core validates `cut_opening` arguments; if wall-endpoint geometry makes two openings collide, the tool returns an error and the script logs the conflict.)
## Exterior elements
**Swimming pool (east of house):**
- Zone polygon: (5, 1.5) (10, 1.5) (10, 1.5) (5, 1.5) — 5 × 3 m.
- Metadata: `{ kind: "pool", depthM: 1.8, finish: "tile" }`.
- Additional slab at elevation 1.8 m to represent the pool basin (same polygon).
**Privacy screen fence (lot perimeter):**
- Style: `privacy`, height 1.8 m.
- Four fence segments around the 20 × 15 lot, with a 2 m gap at the south entrance (x ∈ [1, 1]).
- Segments:
1. South-west: (10, 7.5) → (1, 7.5)
2. South-east: (1, 7.5) → (10, 7.5)
3. East: (10, 7.5) → (10, 7.5)
4. North: (10, 7.5) → (10, 7.5)
5. West: (10, 7.5) → (10, 7.5)
**Garden zone** (everything that isn't building or pool):
- One big zone labelled "garden" with the remaining polygon.
## Success criteria
- `validate_scene` returns `valid: true, errors: 0` after every step.
- Final node count ≥ 30 (1 site + 1 building + 1 level + ~14 walls + 5 fences + ~7 zones + 6 doors + 7 windows + 1 pool slab ≈ 43).
- `export_json` produces a valid parseable JSON.
- `duplicate_level` works (produces a second storey at the same layout).
- Scene exports and imports cleanly: write the export to disk, `unloadScene` via the bridge (if exposed) or setScene from the export, re-validate.
## Non-goals
- Catalog items (no furniture — the catalog is unavailable in headless mode).
- Realistic materials / textures (MCP doesn't set `material`; editor picks defaults).
- Roof geometry — the roof system is render-only; we skip for v0.1.
