# QA before delivery

## Blocking
| Check | Fails when |
|---|---|
| Architecture preserved | Walls, windows, doors or ceiling height moved — the result is a different house and unusable |
| Scale plausibility | Furniture that couldn't physically fit the space |
| Structural honesty | A structural change presented as buildable rather than illustrative |

## Quality
| Check | Fails when |
|---|---|
| Light consistency | Interior light doesn't match the windows |
| Perspective | Furniture at a different vanishing point from the room |
| Staging realism | Styled past the point of believability |
