The agent assembled a reasonably complete answer about QA Studio by working around an inaccessible primary domain (manual.qa.studio returns truncated HTML from a JavaScript SPA) and piecing together information from related domains (qa.studio, education aggregator sites like Pikabu and Habr Career, and web search results). The site's three-domain structure and reliance on client-side rendering made direct navigation difficult, forcing heavy reliance on third-party review aggregators and prior knowledge.

• ›The primary domain manual.qa.studio/ [1, 3] returned only truncated HTML with no meaningful text content—it's a JavaScript SPA that the agent could not render. Related attempts to fetch /pricing, /about, /features all returned 404s, indicating the site doesn't expose its information architecture in crawlable form.
• ›The agent pivoted to qa.studio/ [14] and discovered it was the main landing page with actual content accessible via HTML. Subsequent fetches of education aggregator pages [21, 22] (Habr Career and Pikabu) contained structured course information, pricing, mentor details, and reviews—these third-party aggregators became the primary content sources, not the vendor site itself.
• ›The site's three-domain strategy (manual.qa.studio, qa.studio, auto.qa.studio) is confusing and poorly navigable—the agent explicitly flagged this as unclear and had to use web search to disambiguate that these are subdomains of the same org serving different course specializations, not separate products.
• ›Pricing and course structure came entirely from third-party aggregator pages [21, 22], not from the vendor site. The vendor site appears to publish this information somewhere, but it was not discoverable through direct navigation or in fetched HTML—indicating poor SEO or JavaScript-dependent rendering.
• ›The agent used 12 web searches (steps [9] through [30]) to compensate for the site's poor navigability. Russian-language queries [13, 20, 23, 24, 28, 29] were more productive than English queries, revealing the site is primarily oriented toward Russian-speaking students.
