2025-08-14T20:43:47.7145631Z This runner determinator is used to determine which set of runners to run a
2025-08-14T20:43:47.7146660Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-08-14T20:43:47.7148196Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-08-14T20:43:47.7149156Z of which runners should be used to run which job.
2025-08-14T20:43:47.7149910Z 
2025-08-14T20:43:47.7150570Z The configuration has two parts, the settings and a list of opted-in users,
2025-08-14T20:43:47.7151561Z separated by a line containing "---".  If the line is not present, the
2025-08-14T20:43:47.7152623Z settings are considered to be empty with only the second part, the user
2025-08-14T20:43:47.7153421Z list, defined.
2025-08-14T20:43:47.7153903Z 
2025-08-14T20:43:47.7154582Z The first part is a YAML block that defines the rollout settings. This can be
2025-08-14T20:43:47.7155603Z used to define any settings that are needed to determine which runners to use.
2025-08-14T20:43:47.7156513Z It's fields are defined by the RolloutSettings class below.
2025-08-14T20:43:47.7157515Z 
2025-08-14T20:43:47.7158567Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-08-14T20:43:47.7159534Z The user list is also a comma separated list of additional features or
2025-08-14T20:43:47.7160479Z experiments which the user could be opted in to.
2025-08-14T20:43:47.7161103Z 
2025-08-14T20:43:47.7161588Z The user list has the following rules:
2025-08-14T20:43:47.7162238Z 
2025-08-14T20:43:47.7162884Z - Users are GitHub usernames, which must start with the @ prefix
2025-08-14T20:43:47.7163831Z - Each user is also a comma-separated list of features/experiments to enable
2025-08-14T20:43:47.7164703Z - A "#" prefix opts the user out of all experiments
