[That is the part of our deliverables for the TSAN project for Q3. This is an umbrella ticket that could be split to finer-grained ones if needed.]

Context: As we plan to distribute the responsibility for investigating and resolving newly reported issues across multiple teams, it would be beneficial to provide a reference document. This document should clearly outline the steps for:

1. Investigating the root cause of a TSAN warning

2. Determining whether the warning is a true or false positive

3. Validating and proving the correctness of a proposed fix

Expected Impact: Enable developers to effectively investigate and resolve newly reported synchronization issues.
