2025-11-03T15:43:07.4058675Z This runner determinator is used to determine which set of runners to run a
2025-11-03T15:43:07.4059728Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-11-03T15:43:07.4060886Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-11-03T15:43:07.4061878Z of which runners should be used to run which job.
2025-11-03T15:43:07.4062533Z 
2025-11-03T15:43:07.4063262Z The configuration has two parts, the settings and a list of opted-in users,
2025-11-03T15:43:07.4064303Z separated by a line containing "---".  If the line is not present, the
2025-11-03T15:43:07.4065321Z settings are considered to be empty with only the second part, the user
2025-11-03T15:43:07.4066162Z list, defined.
2025-11-03T15:43:07.4066739Z 
2025-11-03T15:43:07.4067446Z The first part is a YAML block that defines the rollout settings. This can be
2025-11-03T15:43:07.4068481Z used to define any settings that are needed to determine which runners to use.
2025-11-03T15:43:07.4069483Z It's fields are defined by the RolloutSettings class below.
2025-11-03T15:43:07.4070225Z 
2025-11-03T15:43:07.4071141Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-11-03T15:43:07.4072183Z The user list is also a comma separated list of additional features or
2025-11-03T15:43:07.4073058Z experiments which the user could be opted in to.
2025-11-03T15:43:07.4073738Z 
2025-11-03T15:43:07.4074268Z The user list has the following rules:
2025-11-03T15:43:07.4074872Z 
2025-11-03T15:43:07.4075555Z - Users are GitHub usernames, which must start with the @ prefix
2025-11-03T15:43:07.4076676Z - Each user is also a comma-separated list of features/experiments to enable
2025-11-03T15:43:07.4077632Z - A "#" prefix opts the user out of all experiments
2025-11-03T15:43:07.4078277Z 
2025-11-03T15:43:07.4078746Z Example config:
