Every dedicated Birla Opus product identity uses one canonical route under /birla-opus-product/<slug>/.
Every dedicated product identity carries Product JSON-LD with Birla Opus as the brand and the exact canonical URL.
Products are not deleted merely because their family descriptions overlap. Exact product-name duplicates are investigated separately; similar products remain separate when the manufacturer treats them as separate identities.
Exact coverage, packs, mixing ratios, drying times and warranties are published only when supported by the current Birla Opus product page or PIS. Where manufacturer pages conflict, the conflict is preserved for verification rather than guessed away.
Indexable routes are included in the sitemap; legacy /enriched/ compatibility routes are excluded.
The Birla Opus namespace is now structurally audited and frozen. Future catalogue updates should enter through identity → source evidence → duplicate check → canonical → schema → sitemap QA.
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.
