Exact manufacturer page evidence: product-level claims are supported by the exact current Berger product page used in the prior research passes.
Catalogue identity — technical fields source-gated: the current Berger sitemap establishes that the identity exists, but exact coverage, dilution, consumption, drying, pack size, warranty or other numeric specifications are not invented without the exact current PDS/product page.
All dedicated Berger product routes are checked for canonical URL, title, H1 and Product JSON-LD. The sitemap is regenerated from the current route set.
No manufacturer product is deleted simply because names or roles are similar. Exact duplicate labels are treated as taxonomy review items rather than as permission to invent separate technical specifications.
The Berger namespace is now technically evidence-gated and SEO-audited. Future technical additions should enter through exact product/PDS evidence and then pass the same canonical/schema/duplicate checks.
Use dedicated pages for products, brands, services, local information and technical guidance. Manufacturer-specific claims remain source-gated; customer reviews are treated as experience evidence rather than technical proof.
