2025-07-17T06:38:21.1889220Z This runner determinator is used to determine which set of runners to run a
2025-07-17T06:38:21.1891181Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-07-17T06:38:21.1893497Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-07-17T06:38:21.1895348Z of which runners should be used to run which job.
2025-07-17T06:38:21.1896601Z 
2025-07-17T06:38:21.1898063Z The configuration has two parts, the settings and a list of opted-in users,
2025-07-17T06:38:21.1899935Z separated by a line containing "---".  If the line is not present, the
2025-07-17T06:38:21.1901876Z settings are considered to be empty with only the second part, the user
2025-07-17T06:38:21.1903405Z list, defined.
2025-07-17T06:38:21.1904361Z 
2025-07-17T06:38:21.1905558Z The first part is a YAML block that defines the rollout settings. This can be
2025-07-17T06:38:21.1907652Z used to define any settings that are needed to determine which runners to use.
2025-07-17T06:38:21.1909430Z It's fields are defined by the RolloutSettings class below.
2025-07-17T06:38:21.1910842Z 
2025-07-17T06:38:21.1912389Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-07-17T06:38:21.1914354Z The user list is also a comma separated list of additional features or
2025-07-17T06:38:21.1916123Z experiments which the user could be opted in to.
2025-07-17T06:38:21.1917319Z 
2025-07-17T06:38:21.1918270Z The user list has the following rules:
2025-07-17T06:38:21.1919367Z 
2025-07-17T06:38:21.1920417Z - Users are GitHub usernames, which must start with the @ prefix
2025-07-17T06:38:21.1922089Z - Each user is also a comma-separated list of features/experiments to enable
2025-07-17T06:38:21.1923744Z - A "#" prefix opts the user out of all experiments
