<br>
The meeting is structured in two parts. The first half of the week (August 10–12) will feature open science talks covering a broad range of JWST lensing results, as well as broader community discussions, including
<i>“Lensing Surveys: past lessons and future directions”</i>, aimed at shaping the next generation of cluster lensing efforts. These sessions will culminate in the Solar Eclipse on Wednesday afternoon.<br>
<br>
The latter half (August 13–14) will focus more on a mix of open discussion and collaboration meetings, including activities organized within ongoing JWST programs such as VENUS and SLICE.<br>
<br>
We hope this format provides flexibility for all participants: attendees are welcome to join discussion sessions, engage in emerging collaborations, participate in team meetings where appropriate, enjoy Santander and the beach, or depart after the main science
program.<br>
