2025-09-07T06:09:29.5954512Z This runner determinator is used to determine which set of runners to run a
2025-09-07T06:09:29.5955577Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-09-07T06:09:29.5956795Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-09-07T06:09:29.5957913Z of which runners should be used to run which job.
2025-09-07T06:09:29.5958650Z 
2025-09-07T06:09:29.5959392Z The configuration has two parts, the settings and a list of opted-in users,
2025-09-07T06:09:29.5960724Z separated by a line containing "---".  If the line is not present, the
2025-09-07T06:09:29.5961815Z settings are considered to be empty with only the second part, the user
2025-09-07T06:09:29.5962648Z list, defined.
2025-09-07T06:09:29.5963280Z 
2025-09-07T06:09:29.5964014Z The first part is a YAML block that defines the rollout settings. This can be
2025-09-07T06:09:29.5965088Z used to define any settings that are needed to determine which runners to use.
2025-09-07T06:09:29.5966168Z It's fields are defined by the RolloutSettings class below.
2025-09-07T06:09:29.5966905Z 
2025-09-07T06:09:29.5967922Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-09-07T06:09:29.5969064Z The user list is also a comma separated list of additional features or
2025-09-07T06:09:29.5970221Z experiments which the user could be opted in to.
2025-09-07T06:09:29.5970965Z 
2025-09-07T06:09:29.5971508Z The user list has the following rules:
2025-09-07T06:09:29.5972184Z 
2025-09-07T06:09:29.5972875Z - Users are GitHub usernames, which must start with the @ prefix
2025-09-07T06:09:29.5973982Z - Each user is also a comma-separated list of features/experiments to enable
2025-09-07T06:09:29.5974960Z - A "#" prefix opts the user out of all experiments
2025-09-07T06:09:29.5975621Z 
2025-09-07T06:09:29.5976149Z Example config:
