61            <li>Ported the validated Build 16 production-target XDC cleanup into the tracked repository.</li>
62            <li>Preserved positive post-route timing while clearing XDCB-5 and reducing methodology residue to a single documented item.</li>
63            <li>Validated the tracked branch with MCU host regression and FPGA regression/integration suites.</li>
64            <li>Refreshed the bring-up documentation into a pre-arrival readiness package for the FPGA module and carrier board.</li>
65            <li>Kept upstream ADAR1000 bulk imports out of the baseline pending selective, justified reuse only.</li>
