Dear Organizers, Thank you for releasing the test phase materials. While going through the documentation, I had a few questions regarding the current test phase documentation. 1. The test phase page currently states **"Test phase submission – NOTE under drafting."** Could you confirm whether the current documentation is the final version, or if an updated version will be published later? 2. In `CMRx4DFlowReconDemo/ForRecon/3_DataSavingDemo.ipynb`, the example cases appear to come from another challenge. Will this notebook be updated for the CMRx4DFlow challenge? 3. I also noticed an inconsistency regarding the test phase submission policy: * On the FAQ page(https://mrixfields.chihucloud.com/2026/faq.html), it states: > "During the test phase, each team can submit up to five Docker containers per task in total. The final ranking will be based on the results of the last submission." * However, on the Synapse page, it states: > "Participants only have one chance for the test phase, and the final score will be announced during MICCAI 2026." Could you please clarify which policy applies to the test phase? Since the test phase is scheduled to start on July 1, I wanted to check whether these materials are still being finalized or whether the current guidelines should be considered the official version. Thank you very much for your help!
