2025-07-17T06:33:19.7782143Z This runner determinator is used to determine which set of runners to run a
2025-07-17T06:33:19.7783225Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-07-17T06:33:19.7784468Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-07-17T06:33:19.7785486Z of which runners should be used to run which job.
2025-07-17T06:33:19.7786212Z 
2025-07-17T06:33:19.7786944Z The configuration has two parts, the settings and a list of opted-in users,
2025-07-17T06:33:19.7788542Z separated by a line containing "---".  If the line is not present, the
2025-07-17T06:33:19.7789665Z settings are considered to be empty with only the second part, the user
2025-07-17T06:33:19.7790528Z list, defined.
2025-07-17T06:33:19.7791105Z 
2025-07-17T06:33:19.7791840Z The first part is a YAML block that defines the rollout settings. This can be
2025-07-17T06:33:19.7792898Z used to define any settings that are needed to determine which runners to use.
2025-07-17T06:33:19.7793941Z It's fields are defined by the RolloutSettings class below.
2025-07-17T06:33:19.7794664Z 
2025-07-17T06:33:19.7795689Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-07-17T06:33:19.7796780Z The user list is also a comma separated list of additional features or
2025-07-17T06:33:19.7797941Z experiments which the user could be opted in to.
2025-07-17T06:33:19.7798670Z 
2025-07-17T06:33:19.7799148Z The user list has the following rules:
2025-07-17T06:33:19.7799877Z 
2025-07-17T06:33:19.7800572Z - Users are GitHub usernames, which must start with the @ prefix
2025-07-17T06:33:19.7801628Z - Each user is also a comma-separated list of features/experiments to enable
2025-07-17T06:33:19.7802639Z - A "#" prefix opts the user out of all experiments
2025-07-17T06:33:19.7803289Z
