2025-08-26T19:31:43.5213814Z This runner determinator is used to determine which set of runners to run a
2025-08-26T19:31:43.5215018Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-08-26T19:31:43.5216598Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-08-26T19:31:43.5217803Z of which runners should be used to run which job.
2025-08-26T19:31:43.5218660Z 
2025-08-26T19:31:43.5219460Z The configuration has two parts, the settings and a list of opted-in users,
2025-08-26T19:31:43.5220718Z separated by a line containing "---".  If the line is not present, the
2025-08-26T19:31:43.5221936Z settings are considered to be empty with only the second part, the user
2025-08-26T19:31:43.5222964Z list, defined.
2025-08-26T19:31:43.5223552Z 
2025-08-26T19:31:43.5224339Z The first part is a YAML block that defines the rollout settings. This can be
2025-08-26T19:31:43.5225640Z used to define any settings that are needed to determine which runners to use.
2025-08-26T19:31:43.5227032Z It's fields are defined by the RolloutSettings class below.
2025-08-26T19:31:43.5227962Z 
2025-08-26T19:31:43.5228825Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-08-26T19:31:43.5230235Z The user list is also a comma separated list of additional features or
2025-08-26T19:31:43.5231336Z experiments which the user could be opted in to.
2025-08-26T19:31:43.5232117Z 
2025-08-26T19:31:43.5232690Z The user list has the following rules:
2025-08-26T19:31:43.5233361Z 
2025-08-26T19:31:43.5234230Z - Users are GitHub usernames, which must start with the @ prefix
2025-08-26T19:31:43.5235422Z - Each user is also a comma-separated list of features/experiments to enable
2025-08-26T19:31:43.5236563Z - A "#" prefix opts the user out of all experiments
