2025-08-26T19:31:43.7919257Z This runner determinator is used to determine which set of runners to run a
2025-08-26T19:31:43.7920235Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-08-26T19:31:43.7921422Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-08-26T19:31:43.7922355Z of which runners should be used to run which job.
2025-08-26T19:31:43.7922992Z 
2025-08-26T19:31:43.7923729Z The configuration has two parts, the settings and a list of opted-in users,
2025-08-26T19:31:43.7924702Z separated by a line containing "---".  If the line is not present, the
2025-08-26T19:31:43.7925917Z settings are considered to be empty with only the second part, the user
2025-08-26T19:31:43.7926853Z list, defined.
2025-08-26T19:31:43.7927355Z 
2025-08-26T19:31:43.7927996Z The first part is a YAML block that defines the rollout settings. This can be
2025-08-26T19:31:43.7929052Z used to define any settings that are needed to determine which runners to use.
2025-08-26T19:31:43.7930003Z It's fields are defined by the RolloutSettings class below.
2025-08-26T19:31:43.7930910Z 
2025-08-26T19:31:43.7931664Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-08-26T19:31:43.7932640Z The user list is also a comma separated list of additional features or
2025-08-26T19:31:43.7933461Z experiments which the user could be opted in to.
2025-08-26T19:31:43.7934152Z 
2025-08-26T19:31:43.7934600Z The user list has the following rules:
2025-08-26T19:31:43.7935199Z 
2025-08-26T19:31:43.7936161Z - Users are GitHub usernames, which must start with the @ prefix
2025-08-26T19:31:43.7937102Z - Each user is also a comma-separated list of features/experiments to enable
2025-08-26T19:31:43.7937969Z - A "#" prefix opts the user out of all experiments
