2025-08-26T19:31:41.0646957Z This runner determinator is used to determine which set of runners to run a
2025-08-26T19:31:41.0648251Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-08-26T19:31:41.0649664Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-08-26T19:31:41.0650900Z of which runners should be used to run which job.
2025-08-26T19:31:41.0651833Z 
2025-08-26T19:31:41.0652695Z The configuration has two parts, the settings and a list of opted-in users,
2025-08-26T19:31:41.0654050Z separated by a line containing "---".  If the line is not present, the
2025-08-26T19:31:41.0655288Z settings are considered to be empty with only the second part, the user
2025-08-26T19:31:41.0656335Z list, defined.
2025-08-26T19:31:41.0656881Z 
2025-08-26T19:31:41.0657791Z The first part is a YAML block that defines the rollout settings. This can be
2025-08-26T19:31:41.0659100Z used to define any settings that are needed to determine which runners to use.
2025-08-26T19:31:41.0660246Z It's fields are defined by the RolloutSettings class below.
2025-08-26T19:31:41.0661509Z 
2025-08-26T19:31:41.0662663Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-08-26T19:31:41.0663917Z The user list is also a comma separated list of additional features or
2025-08-26T19:31:41.0665095Z experiments which the user could be opted in to.
2025-08-26T19:31:41.0665876Z 
2025-08-26T19:31:41.0666459Z The user list has the following rules:
2025-08-26T19:31:41.0667223Z 
2025-08-26T19:31:41.0668028Z - Users are GitHub usernames, which must start with the @ prefix
2025-08-26T19:31:41.0669206Z - Each user is also a comma-separated list of features/experiments to enable
2025-08-26T19:31:41.0670370Z - A "#" prefix opts the user out of all experiments
2025-08-26T19:31:41.0671371Z
