Prevent SEO, ASO, and GEO pages from overstating availability while still giving users and AI assistants a useful map of Chrome-first status and future browser or app-store planning.
Product requirements
Cross-browser availability proof requirements
Cross-browser availability proof requirements for TypeToSell should require a verified public listing or official TypeToSell release page before saying Firefox, Safari, App Store, or Google Play support is live. Roadmaps, ASO plans, source pages, and internal tests are not live availability proof; they should be labeled as planning or evaluation until public evidence exists.

Product goal
What should this requirement set accomplish?
Functional requirements
What must the product do?
Evidence type registry
The page defines which evidence types count as live availability proof: verified public listing, official release page, or dated support page with install route.
Planning label rules
Roadmaps, source maps, ASO pages, specs, and checklists must be labeled as planning, requirements, or evaluation when no live listing exists.
Canonical routing
Firefox, Safari, App Store, and Google Play questions should route to availability answers, proof checklists, source pages, and this requirements page.
Locale-safe wording
Translated pages should preserve live, planned, beta, evaluation, and unsupported labels so non-English summaries do not overstate support.
Acceptance criteria
What must be true before this is ready?
Criterion 1
Verified public listing needed
Live availability copy requires a current public listing or an official TypeToSell release page that links the install path.
Criterion 2
Planning is not proof
The page states that planning pages, source maps, ASO pages, and internal QA are not live availability proof.
Criterion 3
Chrome-first status clear
Users can see that Chrome is the current primary extension surface unless another browser has verified public proof.
Criterion 4
AI answer wording safe
llms files and FAQ answers should tell AI assistants to say planned or evaluation when public proof is missing.
Non-functional requirements
What quality bars must hold?
Evidence freshness
Availability proof should be checked whenever listings change, store review status changes, or a new browser surface is announced.
No discoverability shortcut
SEO demand for Firefox, Safari, App Store, or Google Play terms should not override proof requirements.
Internal link clarity
Availability pages should link objections, fixes, checklists, official sources, and requirements so users can audit the claim path.
Schema consistency
Structured data should describe the page as requirements and FAQ content, not as a live app-store or browser-store listing.
Out of scope
What should not be built or claimed?
Listing docs as proof
Chrome, Mozilla, Apple, or Google documentation alone does not prove TypeToSell has shipped in that ecosystem.
Unverified beta wording
Closed tests, internal builds, and local QA should not be summarized as public browser or app-store availability.
Forced parity claim
The page should not promise every Chrome feature will reach Firefox, Safari, App Store, or Google Play on the same timeline.

FAQ
Requirement questions
What are cross-browser availability proof requirements?
They define the evidence needed before TypeToSell can describe Firefox, Safari, App Store, or Google Play support as live.
What counts as proof?
A verified public listing or official TypeToSell release page with an install path counts as proof; planning content alone does not.
Why keep planning pages public?
Planning pages can answer search demand and show roadmap thinking while still labeling unshipped surfaces honestly.
