2025-07-17T06:33:20.2925163Z This runner determinator is used to determine which set of runners to run a
2025-07-17T06:33:20.2926950Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-07-17T06:33:20.2929416Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-07-17T06:33:20.2931100Z of which runners should be used to run which job.
2025-07-17T06:33:20.2932309Z 
2025-07-17T06:33:20.2933630Z The configuration has two parts, the settings and a list of opted-in users,
2025-07-17T06:33:20.2935470Z separated by a line containing "---".  If the line is not present, the
2025-07-17T06:33:20.2937540Z settings are considered to be empty with only the second part, the user
2025-07-17T06:33:20.2939369Z list, defined.
2025-07-17T06:33:20.2940225Z 
2025-07-17T06:33:20.2941501Z The first part is a YAML block that defines the rollout settings. This can be
2025-07-17T06:33:20.2943406Z used to define any settings that are needed to determine which runners to use.
2025-07-17T06:33:20.2945020Z It's fields are defined by the RolloutSettings class below.
2025-07-17T06:33:20.2946444Z 
2025-07-17T06:33:20.2947642Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-07-17T06:33:20.2949651Z The user list is also a comma separated list of additional features or
2025-07-17T06:33:20.2951382Z experiments which the user could be opted in to.
2025-07-17T06:33:20.2952735Z 
2025-07-17T06:33:20.2953728Z The user list has the following rules:
2025-07-17T06:33:20.2954931Z 
2025-07-17T06:33:20.2956189Z - Users are GitHub usernames, which must start with the @ prefix
2025-07-17T06:33:20.2957763Z - Each user is also a comma-separated list of features/experiments to enable
2025-07-17T06:33:20.2959565Z - A "#" prefix opts the user out of all experiments
