2025-08-14T20:43:47.1202486Z This runner determinator is used to determine which set of runners to run a
2025-08-14T20:43:47.1203521Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-08-14T20:43:47.1204739Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-08-14T20:43:47.1205640Z of which runners should be used to run which job.
2025-08-14T20:43:47.1206372Z 
2025-08-14T20:43:47.1207024Z The configuration has two parts, the settings and a list of opted-in users,
2025-08-14T20:43:47.1208036Z separated by a line containing "---".  If the line is not present, the
2025-08-14T20:43:47.1209099Z settings are considered to be empty with only the second part, the user
2025-08-14T20:43:47.1209897Z list, defined.
2025-08-14T20:43:47.1210381Z 
2025-08-14T20:43:47.1211081Z The first part is a YAML block that defines the rollout settings. This can be
2025-08-14T20:43:47.1212145Z used to define any settings that are needed to determine which runners to use.
2025-08-14T20:43:47.1213471Z It's fields are defined by the RolloutSettings class below.
2025-08-14T20:43:47.1214502Z 
2025-08-14T20:43:47.1215212Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-08-14T20:43:47.1216171Z The user list is also a comma separated list of additional features or
2025-08-14T20:43:47.1217092Z experiments which the user could be opted in to.
2025-08-14T20:43:47.1217749Z 
2025-08-14T20:43:47.1218205Z The user list has the following rules:
2025-08-14T20:43:47.1218851Z 
2025-08-14T20:43:47.1219469Z - Users are GitHub usernames, which must start with the @ prefix
2025-08-14T20:43:47.1220437Z - Each user is also a comma-separated list of features/experiments to enable
2025-08-14T20:43:47.1221327Z - A "#" prefix opts the user out of all experiments
