2025-08-14T20:43:46.4032592Z This runner determinator is used to determine which set of runners to run a
2025-08-14T20:43:46.4033727Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-08-14T20:43:46.4034949Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-08-14T20:43:46.4036058Z of which runners should be used to run which job.
2025-08-14T20:43:46.4036803Z 
2025-08-14T20:43:46.4037659Z The configuration has two parts, the settings and a list of opted-in users,
2025-08-14T20:43:46.4038861Z separated by a line containing "---".  If the line is not present, the
2025-08-14T20:43:46.4039934Z settings are considered to be empty with only the second part, the user
2025-08-14T20:43:46.4040830Z list, defined.
2025-08-14T20:43:46.4041338Z 
2025-08-14T20:43:46.4042147Z The first part is a YAML block that defines the rollout settings. This can be
2025-08-14T20:43:46.4043260Z used to define any settings that are needed to determine which runners to use.
2025-08-14T20:43:46.4044232Z It's fields are defined by the RolloutSettings class below.
2025-08-14T20:43:46.4045076Z 
2025-08-14T20:43:46.4046084Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-08-14T20:43:46.4047411Z The user list is also a comma separated list of additional features or
2025-08-14T20:43:46.4048474Z experiments which the user could be opted in to.
2025-08-14T20:43:46.4049159Z 
2025-08-14T20:43:46.4049696Z The user list has the following rules:
2025-08-14T20:43:46.4050409Z 
2025-08-14T20:43:46.4051155Z - Users are GitHub usernames, which must start with the @ prefix
2025-08-14T20:43:46.4052190Z - Each user is also a comma-separated list of features/experiments to enable
2025-08-14T20:43:46.4053224Z - A "#" prefix opts the user out of all experiments
