2025-08-14T20:43:47.4645265Z This runner determinator is used to determine which set of runners to run a
2025-08-14T20:43:47.4646322Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-08-14T20:43:47.4647570Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-08-14T20:43:47.4648567Z of which runners should be used to run which job.
2025-08-14T20:43:47.4649271Z 
2025-08-14T20:43:47.4650199Z The configuration has two parts, the settings and a list of opted-in users,
2025-08-14T20:43:47.4651266Z separated by a line containing "---".  If the line is not present, the
2025-08-14T20:43:47.4652317Z settings are considered to be empty with only the second part, the user
2025-08-14T20:43:47.4653240Z list, defined.
2025-08-14T20:43:47.4653742Z 
2025-08-14T20:43:47.4654446Z The first part is a YAML block that defines the rollout settings. This can be
2025-08-14T20:43:47.4655529Z used to define any settings that are needed to determine which runners to use.
2025-08-14T20:43:47.4656567Z It's fields are defined by the RolloutSettings class below.
2025-08-14T20:43:47.4657318Z 
2025-08-14T20:43:47.4658483Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-08-14T20:43:47.4659876Z The user list is also a comma separated list of additional features or
2025-08-14T20:43:47.4660811Z experiments which the user could be opted in to.
2025-08-14T20:43:47.4661556Z 
2025-08-14T20:43:47.4662067Z The user list has the following rules:
2025-08-14T20:43:47.4662712Z 
2025-08-14T20:43:47.4663466Z - Users are GitHub usernames, which must start with the @ prefix
2025-08-14T20:43:47.4664499Z - Each user is also a comma-separated list of features/experiments to enable
2025-08-14T20:43:47.4665433Z - A "#" prefix opts the user out of all experiments
2025-08-14T20:43:47.4666070Z
