Discovery: 31 fixed key names + Chrome UX Report origins + Certificate Transparency (certspotter, 604 names in CT logs). Tiers: primary = merck.com and www; critical = customer-facing or revenue names (login, account, store, marketing/brand, support, developer, downloads) on any owned domain; other = remaining public names (low weight); internal = dev/test/mail/VPN-looking names, excluded from share. "Edge" is the front door a visitor connects to (CDN/WAF or the cloud load balancer). Grey rows did not resolve. Weight = share of the company's traffic-weighted total.

Claimed tech (job postings)

Merck doesn't publish jobs through a public job-board API we use (Greenhouse, Lever or Ashby), so there's no claimed-tech signal yet.
