2025-10-10T00:01:09.7475074Z This runner determinator is used to determine which set of runners to run a
2025-10-10T00:01:09.7476122Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-10-10T00:01:09.7477414Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-10-10T00:01:09.7478442Z of which runners should be used to run which job.
2025-10-10T00:01:09.7479224Z 
2025-10-10T00:01:09.7479948Z The configuration has two parts, the settings and a list of opted-in users,
2025-10-10T00:01:09.7481037Z separated by a line containing "---".  If the line is not present, the
2025-10-10T00:01:09.7482573Z settings are considered to be empty with only the second part, the user
2025-10-10T00:01:09.7483589Z list, defined.
2025-10-10T00:01:09.7484107Z 
2025-10-10T00:01:09.7484988Z The first part is a YAML block that defines the rollout settings. This can be
2025-10-10T00:01:09.7486143Z used to define any settings that are needed to determine which runners to use.
2025-10-10T00:01:09.7487144Z It's fields are defined by the RolloutSettings class below.
2025-10-10T00:01:09.7487964Z 
2025-10-10T00:01:09.7488975Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-10-10T00:01:09.7490047Z The user list is also a comma separated list of additional features or
2025-10-10T00:01:09.7491041Z experiments which the user could be opted in to.
2025-10-10T00:01:09.7491947Z 
2025-10-10T00:01:09.7492502Z The user list has the following rules:
2025-10-10T00:01:09.7493105Z 
2025-10-10T00:01:09.7493920Z - Users are GitHub usernames, which must start with the @ prefix
2025-10-10T00:01:09.7494971Z - Each user is also a comma-separated list of features/experiments to enable
2025-10-10T00:01:09.7496236Z - A "#" prefix opts the user out of all experiments
2025-10-10T00:01:09.7574352Z 
2025-10-10T00:01:09.7574761Z Example config:
