Keeping the broken file in the sample is good proof that batch failure is handled, not just claimed. For review handoff, the manual step we would still watch is scale and orientation normalization: does the fingerprint make those mismatches obvious before the contact sheet is generated?
In v0.1, the fingerprints identify the source file and render settings; they don't compare either against a scale/orientation standard. The manifest records imported world bounds and object transforms, but the contact sheet auto-fits each model. That means a size mismatch can look normal in the thumbnails, and there is no preflight warning.
Which reference would help your handoff: expected physical dimensions, an agreed front/up axis, or consistency across related assets?
