2025-11-03T15:43:06.5961599Z This runner determinator is used to determine which set of runners to run a
2025-11-03T15:43:06.5962661Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-11-03T15:43:06.5963929Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-11-03T15:43:06.5964922Z of which runners should be used to run which job.
2025-11-03T15:43:06.5965633Z 
2025-11-03T15:43:06.5966455Z The configuration has two parts, the settings and a list of opted-in users,
2025-11-03T15:43:06.5967497Z separated by a line containing "---".  If the line is not present, the
2025-11-03T15:43:06.5968527Z settings are considered to be empty with only the second part, the user
2025-11-03T15:43:06.5969626Z list, defined.
2025-11-03T15:43:06.5970148Z 
2025-11-03T15:43:06.5970842Z The first part is a YAML block that defines the rollout settings. This can be
2025-11-03T15:43:06.5971980Z used to define any settings that are needed to determine which runners to use.
2025-11-03T15:43:06.5972995Z It's fields are defined by the RolloutSettings class below.
2025-11-03T15:43:06.5973727Z 
2025-11-03T15:43:06.5974791Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-11-03T15:43:06.5975876Z The user list is also a comma separated list of additional features or
2025-11-03T15:43:06.5976767Z experiments which the user could be opted in to.
2025-11-03T15:43:06.5977525Z 
2025-11-03T15:43:06.5978056Z The user list has the following rules:
2025-11-03T15:43:06.5978666Z 
2025-11-03T15:43:06.5979807Z - Users are GitHub usernames, which must start with the @ prefix
2025-11-03T15:43:06.5980884Z - Each user is also a comma-separated list of features/experiments to enable
2025-11-03T15:43:06.5981827Z - A "#" prefix opts the user out of all experiments
2025-11-03T15:43:06.5982558Z 
2025-11-03T15:43:06.5983069Z Example config:
