Adobe and HTX test media provenance, metadata, watermarking

This is a concrete push toward making altered digital media easier to verify using provenance, metadata, and watermarking. For streaming and video workflows, that matters because authenticity checks are becoming part of the content stack, not just a policy concern. The article does not name other participants or deployment plans, so the main signal to watch is whether HTX and Adobe disclose results from the test or expand it beyond this initial effort.
