2025-08-26T19:31:40.8656742Z This runner determinator is used to determine which set of runners to run a
2025-08-26T19:31:40.8657723Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-08-26T19:31:40.8658903Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-08-26T19:31:40.8659783Z of which runners should be used to run which job.
2025-08-26T19:31:40.8660491Z 
2025-08-26T19:31:40.8661122Z The configuration has two parts, the settings and a list of opted-in users,
2025-08-26T19:31:40.8662354Z separated by a line containing "---".  If the line is not present, the
2025-08-26T19:31:40.8663506Z settings are considered to be empty with only the second part, the user
2025-08-26T19:31:40.8664266Z list, defined.
2025-08-26T19:31:40.8664777Z 
2025-08-26T19:31:40.8665459Z The first part is a YAML block that defines the rollout settings. This can be
2025-08-26T19:31:40.8666493Z used to define any settings that are needed to determine which runners to use.
2025-08-26T19:31:40.8667462Z It's fields are defined by the RolloutSettings class below.
2025-08-26T19:31:40.8668384Z 
2025-08-26T19:31:40.8669084Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-08-26T19:31:40.8670004Z The user list is also a comma separated list of additional features or
2025-08-26T19:31:40.8670933Z experiments which the user could be opted in to.
2025-08-26T19:31:40.8671575Z 
2025-08-26T19:31:40.8672005Z The user list has the following rules:
2025-08-26T19:31:40.8672811Z 
2025-08-26T19:31:40.8673415Z - Users are GitHub usernames, which must start with the @ prefix
2025-08-26T19:31:40.8674391Z - Each user is also a comma-separated list of features/experiments to enable
2025-08-26T19:31:40.8675322Z - A "#" prefix opts the user out of all experiments
