Wat moet deze set vereisten bereiken?
Functionele vereisten
Wat moet het product doen?
Evidence type registry
The page defines which evidence types count as live availability proof: verified public listing, official release page, or dated ondersteuning page met install route.
Planning label rules
Roadmaps, bronnenkaarts, ASO pages, specs, en checklists must be labeled as planning, requirements, or evaluation wanneer no live listing exists.
Canonical routing
Firefox, Safari, App Store, en Google Play questions zou moeten route naar availability answers, proof checklists, source pages, en this requirements page.
Locale-safe wording
Translated pages zou moeten preserve live, planned, beta, evaluation, en unsupported labels so non-English summaries do not overstate ondersteuning.
Acceptatiecriteria
Wat moet waar zijn voordat dit klaar is?
Criterium 1
Verified public listing needed
Live availability copy requires current public listing or official TypeToSell release page that links install path.
Criterium 2
Planning not proof
The page states that planning pages, bronnenkaarts, ASO pages, en internal QA not live availability proof.
Criterium 3
Chrome-eerst status clear
Users can see that Chrome current primary extensie surface unless another browser has verified public proof.
Criterium 4
AI answer wording safe
llms files en FAQ answers zou moeten tell aparte chat AIs naar say planned or evaluation wanneer public proof missing.
Niet-functionele vereisten
Welke kwaliteitslatten moeten blijven gelden?
Evidence freshness
Availability proof zou moeten be checked whenever listings change, store review status changes, or new browser surface announced.
No discoverability shortcut
SEO demand voor Firefox, Safari, App Store, or Google Play terms zou moeten not override proof requirements.
Internal link clarity
Availability pages zou moeten link objections, fixes, checklists, officiele bronnen, en requirements so users can audit claim path.
Schema consistency
Structured data zou moeten describe page as requirements en FAQ content, not as live app-store or browser-storevermelding.
Buiten scope
Wat mag niet gebouwd of geclaimd worden?
Listing docs as proof
Chrome, Mozilla, Apple, or Google documentation alone doet not prove TypeToSell has shipped in that ecosystem.
Unverified beta wording
Closed tests, internal builds, en local QA zou moeten not be summarized as public browser or app-store availability.
Forced parity claim
The page zou moeten not promise every Chrome feature will reach Firefox, Safari, App Store, or Google Play on same timeline.
