2025-07-17T06:33:20.6058670Z This runner determinator is used to determine which set of runners to run a
2025-07-17T06:33:20.6059673Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-07-17T06:33:20.6060976Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-07-17T06:33:20.6061955Z of which runners should be used to run which job.
2025-07-17T06:33:20.6063144Z 
2025-07-17T06:33:20.6063923Z The configuration has two parts, the settings and a list of opted-in users,
2025-07-17T06:33:20.6065006Z separated by a line containing "---".  If the line is not present, the
2025-07-17T06:33:20.6066127Z settings are considered to be empty with only the second part, the user
2025-07-17T06:33:20.6066985Z list, defined.
2025-07-17T06:33:20.6067525Z 
2025-07-17T06:33:20.6068232Z The first part is a YAML block that defines the rollout settings. This can be
2025-07-17T06:33:20.6069342Z used to define any settings that are needed to determine which runners to use.
2025-07-17T06:33:20.6070350Z It's fields are defined by the RolloutSettings class below.
2025-07-17T06:33:20.6071099Z 
2025-07-17T06:33:20.6072481Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-07-17T06:33:20.6073515Z The user list is also a comma separated list of additional features or
2025-07-17T06:33:20.6074474Z experiments which the user could be opted in to.
2025-07-17T06:33:20.6075195Z 
2025-07-17T06:33:20.6075701Z The user list has the following rules:
2025-07-17T06:33:20.6076374Z 
2025-07-17T06:33:20.6077067Z - Users are GitHub usernames, which must start with the @ prefix
2025-07-17T06:33:20.6078104Z - Each user is also a comma-separated list of features/experiments to enable
2025-07-17T06:33:20.6079066Z - A "#" prefix opts the user out of all experiments
