It seems there may have been a misunderstanding or a technical issue, as the issue description you provided is undefined. To create a suitable summary for an advanced developer regarding an issue in the Thanos project, I would need specific details about the issue itself.

Typically, a good issue summary should include the following elements:

  1. Issue Title: A concise title that encapsulates the essence of the problem.
  2. Description: A detailed explanation of the problem, including what is affected, steps to reproduce, and expected versus actual behavior.
  3. Environment: Information on the environment where the issue occurs (version of Thanos, configurations, etc.).
  4. Reproduction Steps: Specific steps required to replicate the issue.
  5. Proposed Solution or Discussion Points: If applicable, what potential solutions or discussions are being suggested.

If you can provide some specific information or context regarding the issue you want summarized, I’ll be glad to help craft a summary tailored for advanced developers familiar with the Thanos project.
