Hi WG,

Thank you for the valuable feedback shared on the mailing list. Based on the community’s input, we have now updated the draft accordingly.

Specifically, we have added a dedicated subsection 4.4 to explicitly describe the handling of multiple Segment Lists within a Candidate Path, including how SL exclusion impacts CP bandwidth and overall eligibility. We have also enhanced section 4.5 to better explain how quality metrics such as bandwidth and latency are collected and applied during path selection, with the aim of mitigating the impact of quality metrics changes.

We truly appreciate your continued support and welcome further feedback from the community as we progress this work.

Best regards,Yisong
