2025-11-03T15:43:06.7297265Z This runner determinator is used to determine which set of runners to run a
2025-11-03T15:43:06.7298365Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-11-03T15:43:06.7299698Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-11-03T15:43:06.7301063Z of which runners should be used to run which job.
2025-11-03T15:43:06.7301771Z 
2025-11-03T15:43:06.7302519Z The configuration has two parts, the settings and a list of opted-in users,
2025-11-03T15:43:06.7303715Z separated by a line containing "---".  If the line is not present, the
2025-11-03T15:43:06.7304771Z settings are considered to be empty with only the second part, the user
2025-11-03T15:43:06.7305662Z list, defined.
2025-11-03T15:43:06.7306259Z 
2025-11-03T15:43:06.7306990Z The first part is a YAML block that defines the rollout settings. This can be
2025-11-03T15:43:06.7308087Z used to define any settings that are needed to determine which runners to use.
2025-11-03T15:43:06.7309150Z It's fields are defined by the RolloutSettings class below.
2025-11-03T15:43:06.7309927Z 
2025-11-03T15:43:06.7311195Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-11-03T15:43:06.7312342Z The user list is also a comma separated list of additional features or
2025-11-03T15:43:06.7313315Z experiments which the user could be opted in to.
2025-11-03T15:43:06.7314003Z 
2025-11-03T15:43:06.7314610Z The user list has the following rules:
2025-11-03T15:43:06.7315244Z 
2025-11-03T15:43:06.7315977Z - Users are GitHub usernames, which must start with the @ prefix
2025-11-03T15:43:06.7317047Z - Each user is also a comma-separated list of features/experiments to enable
2025-11-03T15:43:06.7318025Z - A "#" prefix opts the user out of all experiments
2025-11-03T15:43:06.7318731Z 
2025-11-03T15:43:06.7319228Z Example config:
