Partial profile heuristics only. EInvoiceLab provides browser-side inspection, preparation and routing tools. Full authority acceptance, protected registry responses, certificate trust and official schema conformance remain with the named authority or official validation stack.
Native keyword research status: Expanded native-language intent seed set; validate volume and phrasing with GSC/Keyword Planner. Exact volumes and prioritization still require live Search Console or Keyword Planner data after pages begin receiving impressions.
