<h3>[ A ] Find real email by username</h3>
<p>Combines several sources, strongest signal first.</p>
<ol>
<li><code>GET /users/{u}</code> — fetch profile (display name used for ranking)</li>
<li><code>GET /users/{u}/gpg_keys</code> — user-uploaded PGP keys.
Each UID exposes <code>{email, verified}</code>. This is the strongest
signal: the user uploaded the key themselves, and <code>verified: true</code>
means GitHub confirmed the mailbox. Marked with the <span class="badge match">gpg verified</span> badge.</li>
<li><code>GET /users/{u}/events/public?per_page=100</code><br>
→ iterate <code>PushEvent.payload.commits[].author.{email, name}</code><br>
→ covers roughly the last 90 days of public activity</li>
<li><code>GET /search/commits?q=author:{u}&per_page=100</code> (paginated, cap ~1000)<br>
→ catches commits in <em>any</em> public repo, not just the user's own;
surfaces old emails that fell out of the 90-day events window.
This is what GitFive's "lite" mode does too.</li>
<li>If the steps above returned only noreply addresses, fall back to:
<ul>
<li><code>GET /users/{u}/repos?sort=updated</code> — list non-fork repos</li>
<li><code>GET /repos/{owner}/{repo}/commits?author={u}</code> — commits attributed to this account</li>
</ul>
</li>
<li>Rank: gpg-verified → gpg-uploaded → name match against profile → commit count</li>
</ol>
<h3>[ B ] Extract emails from commits</h3>
<p>Walks every commit reachable from a target (a user or a single repo) and
collects author + committer identities.</p>
<ol>
<li>Resolve target — username OR <code>owner/repo</code></li>
<li>List repos via <code>GET /users/{u}/repos?per_page=100&page={n}</code> (paginated, forks optionally skipped)</li>
<li>For each repo: <code>GET /repos/{owner}/{repo}/commits?per_page=100&page={n}</code></li>
<li>For each commit collect:
<ul>
<li><code>commit.author.{email, name}</code> + top-level <code>author.login</code></li>
<li><code>commit.committer.{email, name}</code> + top-level <code>committer.login</code></li>
</ul>
</li>
<li>Dedupe by lowercased email; aggregate counts and source repos</li>
</ol>
<h3>Commit-message trailer extraction</h3>
<p>For every commit body we also parse well-known git trailers and treat
each match as a separate identity:</p>
<ul>
<li><code>Signed-off-by:</code> — DCO sign-off (Linux kernel, Docker, k8s, many enterprise projects)</li>
<li><code>Co-authored-by:</code> — GitHub's co-authorship trailer (squash-merged PRs)</li>
<li><code>Reviewed-by:</code>, <code>Tested-by:</code>, <code>Acked-by:</code>, <code>Reported-by:</code>, <code>Suggested-by:</code>, <code>Cc:</code> — patch-review chains</li>
</ul>
<p>Trailer emails are highly intentional — they are added by tooling
(<code>git commit -s</code>, the GitHub UI, kernel-style patch review) and
typically point to real mailboxes of the people who reviewed, co-authored,
or signed off on the commit. They are merged into the results table by
email, so a single row may have come from author, committer and several
trailer lines at once.</p>
<h3>Service-noreply filter</h3>
<p>When the checkbox is on, addresses that are obviously machine-generated
vendor noreplies are dropped before being recorded:</p>
<ul>
<li><code>noreply@*</code> / <code>no-reply@*</code> / <code>donotreply@*</code> from any domain
(e.g. <code>noreply@github.com</code>, <code>noreply@anthropic.com</code> from
Claude-Code co-author lines, vendor CI bots, etc.)</li>
<li><code>{id}+{login}@users.noreply.github.com</code> — generated when a user
enables "Keep my email address private"</li>
</ul>
<div class="warn">
<h3>! Warning — commit emails can be forged</h3>
<p>Git records whatever <code>user.email</code> / <code>user.name</code> is set
locally; GitHub does not verify these for unsigned commits. Anyone can push a
commit claiming to be authored by <code>torvalds@kernel.org</code> with the
name "Linus Torvalds".</p>
<ul>
<li>The <strong>Github login</strong> column shows the account GitHub
actually resolved the commit email to — that is the only verified signal.</li>
<li>The <code>match</code> badge in mode A only means the commit author name
equals the public profile name — still circumstantial.</li>
<li>A commit's <code>verified</code> status (GPG/SSH/S/MIME signature) is the
proper trust check; this tool does not currently filter on it.</li>
<li>The system-email filter only hides synthetic addresses; it does not
validate anything.</li>
</ul>
<p style="margin-bottom:0;"><strong>TL;DR:</strong> anything in a commit field
is user-controllable. Treat results as <em>leads</em>, always cross-reference
before claiming attribution.</p>
