+            across edtech (Dyslexia.ai), AI tooling (<a href="https://github.com/Round-Tower/m1k3">M1K3</a>,
+            an on-device LLM assistant), maps (Cartogram), meditation (Rubin), and a

+
+        <h2>Why MurphySig exists</h2>
+        <p>
+            I've shipped a lot of AI-collaborative code, and I started losing track of what
+            <em>I</em> wrote, what the model wrote, what we wrote together, and how confident
+            I was when I wrote it. MurphySig is the convention I built to stop that —
+            a comment block that records who made what, when, with what confidence, and
+            what remained uncertain. The <a href="/spec">spec</a> is the standard;
+            the <a href="/whitepaper">whitepaper</a> is the argument.
+        </p>
+
+        <h2>How the claims here are made</h2>
+        <p>
+            Every behavioural claim on this site is backed by a
+            <a href="/benchmark">reproducible benchmark</a> — and when a result doesn't
+            survive a control or a re-score, the correction is published, not buried:
+            the v0.4 spec <a href="/benchmark">deleted an unsupported claim</a>, and one
+            quotable headline <a href="/rescore">didn't survive re-scoring</a> and says so
+            in public. I also use the convention daily on my own repos —
+            126+ signed commits in the first 90 days, documented in the
+            <a href="/launch">field report</a>.
