01
Generation acknowledged
The provider must return a completed job and an output URL. A queued or provider-side success event alone is not presented as a finished asset.

What “ready” means at SVG Genie 3D
A generated file should be retrievable, structurally valid, privately stored, and inspectable before we call the job complete. This is the current automated contract—and the human checks it cannot replace.
02
Output retrieved
SVG Genie downloads the generated asset server-side within a bounded timeout. Empty, unreachable, and oversized responses fail closed.
03
GLB structure checked
The payload must have the glTF binary magic bytes, version 2, and an internally declared length consistent with the downloaded file.
04
Stored privately
Accepted assets are copied into private object storage. Downloads use time-limited signed URLs instead of depending permanently on a provider URL.
05
User access restored on failure
If the provider fails, retrieval fails, validation rejects the asset, or storage fails, the reserved preview or purchased credits are returned.

The next quality layer
We are extending this standard toward mesh parsing, non-manifold edge detection, degenerate-triangle checks, normal consistency, and printability diagnostics. We will update this page when each check is actually shipped—not before.
