Public org commits reveal company email patterns better than finders

Email-format pages (LeadIQ, RocketReach, SignalHire) can contradict each other on both domain and pattern, especially after a company has rebranded across several domains. To see what staff really use, list the org's non-fork repos with gh api orgs/<org>/repos, then read repos/<r>/commits --jq '.commit.author.email'. Filter out upstream authors, because forked repos are full of unrelated committers. In this case the oldest domain was still the one in use, while finder sites favoured newer marketing domains.
