2025-07-17T06:33:30.8117836Z This runner determinator is used to determine which set of runners to run a
2025-07-17T06:33:30.8118863Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-07-17T06:33:30.8120205Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-07-17T06:33:30.8121148Z of which runners should be used to run which job.
2025-07-17T06:33:30.8121907Z 
2025-07-17T06:33:30.8122552Z The configuration has two parts, the settings and a list of opted-in users,
2025-07-17T06:33:30.8123623Z separated by a line containing "---".  If the line is not present, the
2025-07-17T06:33:30.8124664Z settings are considered to be empty with only the second part, the user
2025-07-17T06:33:30.8125478Z list, defined.
2025-07-17T06:33:30.8125946Z 
2025-07-17T06:33:30.8126661Z The first part is a YAML block that defines the rollout settings. This can be
2025-07-17T06:33:30.8127739Z used to define any settings that are needed to determine which runners to use.
2025-07-17T06:33:30.8128670Z It's fields are defined by the RolloutSettings class below.
2025-07-17T06:33:30.8129698Z 
2025-07-17T06:33:30.8130478Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-07-17T06:33:30.8131487Z The user list is also a comma separated list of additional features or
2025-07-17T06:33:30.8132441Z experiments which the user could be opted in to.
2025-07-17T06:33:30.8133120Z 
2025-07-17T06:33:30.8133600Z The user list has the following rules:
2025-07-17T06:33:30.8134238Z 
2025-07-17T06:33:30.8134857Z - Users are GitHub usernames, which must start with the @ prefix
2025-07-17T06:33:30.8135782Z - Each user is also a comma-separated list of features/experiments to enable
2025-07-17T06:33:30.8136722Z - A "#" prefix opts the user out of all experiments
