string
`fileHashes[0]` of the source that produced the plates' `thumbnailRenderedUri`. Re-extraction carries the renders forward only while this still matches the part's current source; a replaced file leaves them behind rather than showing the previous model's geometry.

thumbnailRenderedUrioptional
string
The plate re-rendered by the three.js builder. Written by a different flow, and to a different storage path, than the archive copy above — a later metadata reprocess re-copies the archive image and must not be able to overwrite this. Prefer it over `thumbnailUploadedUri` (see `plateThumbnailUri`).
thumbnailUploadedUrioptional
string
The archive's own plate preview, copied out at metadata-extraction time.
topDataoptional
string
Base64 PNG data for the top/pick images, staged before upload then cleared.
topFileoptional
string
topUploadedUrioptional
string
Uploaded URIs for the plate's top-down image and color-coded object pick mask. Used by the visual skip-objects picker.
