&lt;li&gt;Couples &lt;strong&gt;Φ₃ / excess³&lt;/strong&gt; into &lt;strong&gt;RECD&lt;/strong&gt; dynamics (bilingual EN + ES).&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Proposal 1&lt;/strong&gt; (default): legacy RECD increment × surplus-gated gain Γ₃ with activation gate A₃.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Proposal 2&lt;/strong&gt; (experimental): dual-channel advance of the discrete clock.&lt;/li&gt;
&lt;li&gt;Shifts Φ₃ from a &lt;em&gt;parallel&lt;/em&gt; metric toward a &lt;em&gt;structural&lt;/em&gt; clock contribution.&lt;/li&gt;
