2025-11-03T15:43:06.7080506Z This runner determinator is used to determine which set of runners to run a
2025-11-03T15:43:06.7081898Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-11-03T15:43:06.7083186Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-11-03T15:43:06.7084297Z of which runners should be used to run which job.
2025-11-03T15:43:06.7085016Z 
2025-11-03T15:43:06.7085776Z The configuration has two parts, the settings and a list of opted-in users,
2025-11-03T15:43:06.7087004Z separated by a line containing "---".  If the line is not present, the
2025-11-03T15:43:06.7088094Z settings are considered to be empty with only the second part, the user
2025-11-03T15:43:06.7089036Z list, defined.
2025-11-03T15:43:06.7089533Z 
2025-11-03T15:43:06.7090316Z The first part is a YAML block that defines the rollout settings. This can be
2025-11-03T15:43:06.7091847Z used to define any settings that are needed to determine which runners to use.
2025-11-03T15:43:06.7092913Z It's fields are defined by the RolloutSettings class below.
2025-11-03T15:43:06.7093792Z 
2025-11-03T15:43:06.7094791Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-11-03T15:43:06.7095891Z The user list is also a comma separated list of additional features or
2025-11-03T15:43:06.7096947Z experiments which the user could be opted in to.
2025-11-03T15:43:06.7097651Z 
2025-11-03T15:43:06.7098166Z The user list has the following rules:
2025-11-03T15:43:06.7098859Z 
2025-11-03T15:43:06.7099597Z - Users are GitHub usernames, which must start with the @ prefix
2025-11-03T15:43:06.7100652Z - Each user is also a comma-separated list of features/experiments to enable
2025-11-03T15:43:06.7101904Z - A "#" prefix opts the user out of all experiments
2025-11-03T15:43:06.7102628Z 
2025-11-03T15:43:06.7103077Z Example config:
