2025-07-17T06:33:20.2817474Z This runner determinator is used to determine which set of runners to run a
2025-07-17T06:33:20.2818552Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-07-17T06:33:20.2819765Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-07-17T06:33:20.2820922Z of which runners should be used to run which job.
2025-07-17T06:33:20.2821665Z 
2025-07-17T06:33:20.2822407Z The configuration has two parts, the settings and a list of opted-in users,
2025-07-17T06:33:20.2823483Z separated by a line containing "---".  If the line is not present, the
2025-07-17T06:33:20.2824579Z settings are considered to be empty with only the second part, the user
2025-07-17T06:33:20.2825457Z list, defined.
2025-07-17T06:33:20.2825957Z 
2025-07-17T06:33:20.2826996Z The first part is a YAML block that defines the rollout settings. This can be
2025-07-17T06:33:20.2828081Z used to define any settings that are needed to determine which runners to use.
2025-07-17T06:33:20.2829046Z It's fields are defined by the RolloutSettings class below.
2025-07-17T06:33:20.2829842Z 
2025-07-17T06:33:20.2830692Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-07-17T06:33:20.2831989Z The user list is also a comma separated list of additional features or
2025-07-17T06:33:20.2832965Z experiments which the user could be opted in to.
2025-07-17T06:33:20.2833630Z 
2025-07-17T06:33:20.2834153Z The user list has the following rules:
2025-07-17T06:33:20.2834787Z 
2025-07-17T06:33:20.2835521Z - Users are GitHub usernames, which must start with the @ prefix
2025-07-17T06:33:20.2836507Z - Each user is also a comma-separated list of features/experiments to enable
2025-07-17T06:33:20.2837482Z - A "#" prefix opts the user out of all experiments
2025-07-17T06:33:20.2838182Z
