Field note
Gemini now lets users control the visible watermark on saved images while retaining SynthID and C2PA provenance.
New Runtime reading: The change separates presentation from machine-readable origin signals. Its value depends on durable metadata through downloads and edits, plus interfaces that let recipients inspect provenance without treating it as a truth guarantee.
Evidence boundary: this item uses the listed public sources and keeps vendor, author, or reporter claims attributed. The queued page is an editorial synthesis, not an independent validation of every reported metric.
