Reported failure modes come from papers and vendor caveats, not studio accounts. RealMaster (research, GTA-V) reports identity drift and colour shifts in an Aleph baseline, flicker and identity fluctuation from multiple image-edit anchors, face-structure loss under depth conditioning, and temporal artifacts under fast motion. NVIDIA reports hallucinated or misoriented vehicles for Transfer1 AV variants and error accumulation over long clips, and Transfer1 papers show geometry errors for single controls (segmentation-only headings). Vendor docs warn that high control weight can cost quality and that image-sourced subjects may be inconsistent.

Curator qualifications: All excerpts located; failure modes from papers/vendor caveats; modality-advice disagreement (depth loses faces vs depth fixes headings) kept as task-dependent.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
