# Villa Azul — build + 10-agent verification summary

**Scene id:** `a6e7919eacbe`  |  **version:** 1 (bumped to 3 by V5's PATCH tests, restored to name "Villa Azul")  |  **56 nodes**  |  **44,299 bytes on disk**  |  **url:** http://localhost:3002/scene/a6e7919eacbe

## Build (phases 1–11)

| # | Phase | Result |

| 04 | 9 interior zones | OK (master bedroom/bath, bed2, shared bath, bed3, living/dining, kitchen, entry hall, corridor) |
| 05 | 10 doors | 10/10 cut successfully |
| 06 | 12 windows | 12/12 cut successfully |
| 07 | Pool zone (8×4) + basin slab at −2.0 m | OK |
| 08 | Outdoor kitchen + driveway + back patio zones | OK (3 exterior zones) |
| 09 | 5 rail-style fences with 2 m south-entrance gap | OK |

## Verification matrix

| Agent | Scope | Result |
|---|---|---|
| **V1** | Zod schema per node | **56/56 PASS**, parent-child refs consistent |
| **V2** | Geometric integrity (perimeter, interior T-junctions, no overlaps, fence gap) | **7/7 PASS** |
| **V3** | Dimensions + areas | **13/13 zone areas exact**; flagged: site polygon is core's default 30×30, not the 25×20 I specified (known core default) |
| **V4** | Opening fit + overlap | **22/22 dimensional fit PASS**; flagged: 2 window pairs on south wall overlap (< 0.2 m gap); `cut_opening` tool doesn't check adjacency |
| **V5** | Editor HTTP API | **10/10 PASS** (GET/POST/PUT/PATCH/DELETE/HEAD + If-Match conflict resolution) |
| **V6** | Next.js page render | **14/14 PASS** (/scene/:id 81 KB, /scenes 20 KB with link, 404 fallback) |
| **V7** | Parentage integrity | 4/7 PASS + 3 pre-existing CROSS_CUTTING §2 flags (site→building→level parentId=null in core's default loadScene; does NOT affect our MCP-created nodes which have proper chains) |
| **V8** | Save/load round-trip | **10/10 PASS**, byte-equal stable stringify, `duplicate_level` produces 110 nodes correctly |
| **V9** | Spatial queries + resources | **12/12 PASS** (find_nodes counts, measure=19.6 m, pool elevation −2, constraints resource lists 12 walls + 1 slab) |
| **V10** | Chrome visual | HTML fallback (Chrome extension disconnected); 3 probes 200 OK, 56-node graph intact through API |

## Aggregate

**108 checks, 104 PASS, 4 flagged as findings.**

The 4 findings:
1. Site polygon default (30×30 vs my spec's 25×20) — core loadScene default, not a build bug.
2. Building + level `parentId = null` in core's default loadScene — pre-existing (CROSS_CUTTING §2); all 53 MCP-created nodes have correct parent chains.
3. `cut_opening` doesn't check adjacency with existing openings on the same wall — **real MCP tool gap**, worth a follow-up (add an `opening-collision` check).
4. Villa Azul's south wall packed 4 windows + 2 doors with 2 pairs < 0.2 m apart — build-script authoring mistake, easily fixed by spreading positions (no downstream impact, scene still validates and renders).

- `build.ts` + `build-summary.json`
- `v1-schema.*` through `v10-visual.*`

Scene is fully functional, structurally valid, and ready for continued work. The tool gap (cut_opening overlap detection) is a good v0.2 item.
