2025-08-26T19:31:43.0252913Z This runner determinator is used to determine which set of runners to run a
2025-08-26T19:31:43.0253893Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-08-26T19:31:43.0255083Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-08-26T19:31:43.0255991Z of which runners should be used to run which job.
2025-08-26T19:31:43.0256718Z 
2025-08-26T19:31:43.0257390Z The configuration has two parts, the settings and a list of opted-in users,
2025-08-26T19:31:43.0258416Z separated by a line containing "---".  If the line is not present, the
2025-08-26T19:31:43.0259446Z settings are considered to be empty with only the second part, the user
2025-08-26T19:31:43.0260296Z list, defined.
2025-08-26T19:31:43.0260813Z 
2025-08-26T19:31:43.0261438Z The first part is a YAML block that defines the rollout settings. This can be
2025-08-26T19:31:43.0262852Z used to define any settings that are needed to determine which runners to use.
2025-08-26T19:31:43.0263836Z It's fields are defined by the RolloutSettings class below.
2025-08-26T19:31:43.0264751Z 
2025-08-26T19:31:43.0265582Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-08-26T19:31:43.0266550Z The user list is also a comma separated list of additional features or
2025-08-26T19:31:43.0267468Z experiments which the user could be opted in to.
2025-08-26T19:31:43.0268152Z 
2025-08-26T19:31:43.0268615Z The user list has the following rules:
2025-08-26T19:31:43.0269259Z 
2025-08-26T19:31:43.0269907Z - Users are GitHub usernames, which must start with the @ prefix
2025-08-26T19:31:43.0270905Z - Each user is also a comma-separated list of features/experiments to enable
2025-08-26T19:31:43.0271745Z - A "#" prefix opts the user out of all experiments
2025-08-26T19:31:43.0272682Z
