2025-08-14T20:43:47.7915995Z This runner determinator is used to determine which set of runners to run a
2025-08-14T20:43:47.7917041Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-08-14T20:43:47.7918273Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-08-14T20:43:47.7919271Z of which runners should be used to run which job.
2025-08-14T20:43:47.7920094Z 
2025-08-14T20:43:47.7920922Z The configuration has two parts, the settings and a list of opted-in users,
2025-08-14T20:43:47.7922010Z separated by a line containing "---".  If the line is not present, the
2025-08-14T20:43:47.7923018Z settings are considered to be empty with only the second part, the user
2025-08-14T20:43:47.7923940Z list, defined.
2025-08-14T20:43:47.7924444Z 
2025-08-14T20:43:47.7925151Z The first part is a YAML block that defines the rollout settings. This can be
2025-08-14T20:43:47.7926287Z used to define any settings that are needed to determine which runners to use.
2025-08-14T20:43:47.7927267Z It's fields are defined by the RolloutSettings class below.
2025-08-14T20:43:47.7928011Z 
2025-08-14T20:43:47.7929000Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-08-14T20:43:47.7930190Z The user list is also a comma separated list of additional features or
2025-08-14T20:43:47.7931111Z experiments which the user could be opted in to.
2025-08-14T20:43:47.7931808Z 
2025-08-14T20:43:47.7932346Z The user list has the following rules:
2025-08-14T20:43:47.7932949Z 
2025-08-14T20:43:47.7933692Z - Users are GitHub usernames, which must start with the @ prefix
2025-08-14T20:43:47.7934741Z - Each user is also a comma-separated list of features/experiments to enable
2025-08-14T20:43:47.7935690Z - A "#" prefix opts the user out of all experiments
