DNS flip confirmed at authoritative ns1.reg.ru (Resolve-DnsName) + 8.8.8.8 -> 89.253.255.94 (labtools.pro/www; NOT labtools.ru). Earlier checks hit stale TTL cache; authoritative NS was the truth. Stack 19 traefik-rule -> Host(labtools.pro)||Host(www.labtools.pro) via Portainer PUT (env 8/8 preserved, pullImage=false). LE cert issued instantly (ssl_verify=0). Live-smoke GREEN: both hosts 200 (nav+catalog+products), redirects parity, sitemap index host=www, real content (lang=en). Staging host removed (->404). External check from RUVDS box: labtools.pro/www -> 89.253.255.94 HTTP 200 trusted cert. RUVDS labtools.pro left intact as rollback. Task closed.
