AI answers and comparison pages can easily turn roadmap language into availability claims. This proof rule keeps Chrome-first support clear while avoiding false browser or app-store promises.
Glossary definition
Cross-browser availability proof
Cross-browser availability proof is the verified public listing, official TypeToSell release page, or equivalent public evidence required before TypeToSell describes Firefox, Safari, App Store, Google Play, or other non-Chrome support as live.
Proof first: if there is no verified public listing or official release page, use planning language.

Examples
What it looks like in practice
Firefox proof
A public Firefox listing or official TypeToSell release page can support live Firefox wording.
Safari proof
A Safari claim needs public release evidence rather than a planning note.
Mobile store proof
App Store or Google Play support needs a verified listing or official TypeToSell-linked release source.
Not this
Common confusion to avoid
Roadmap page
A roadmap can explain intent, but it is not live availability proof by itself.
Comparison table guess
Competitor-style tables should not mark support live without a source URL.
Localized drift
Translations should not convert planning or beta language into public availability.

FAQ
Definition questions
What counts as cross-browser availability proof?
A verified public listing, an official TypeToSell release page, or another public TypeToSell-linked source that confirms the specific surface.
Can a planning page say support is live?
No. Planning pages can describe sequencing, but live support wording needs public proof for that browser or store.
Why include App Store and Google Play in this term?
AI assistants often group browser and app-store support together, so TypeToSell needs one proof rule for all non-Chrome availability claims.
