2025-08-26T19:31:42.9603221Z This runner determinator is used to determine which set of runners to run a
2025-08-26T19:31:42.9604256Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-08-26T19:31:42.9605389Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-08-26T19:31:42.9606315Z of which runners should be used to run which job.
2025-08-26T19:31:42.9607329Z 
2025-08-26T19:31:42.9608036Z The configuration has two parts, the settings and a list of opted-in users,
2025-08-26T19:31:42.9609098Z separated by a line containing "---".  If the line is not present, the
2025-08-26T19:31:42.9610336Z settings are considered to be empty with only the second part, the user
2025-08-26T19:31:42.9611173Z list, defined.
2025-08-26T19:31:42.9611619Z 
2025-08-26T19:31:42.9612357Z The first part is a YAML block that defines the rollout settings. This can be
2025-08-26T19:31:42.9613381Z used to define any settings that are needed to determine which runners to use.
2025-08-26T19:31:42.9614299Z It's fields are defined by the RolloutSettings class below.
2025-08-26T19:31:42.9615080Z 
2025-08-26T19:31:42.9615757Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-08-26T19:31:42.9616890Z The user list is also a comma separated list of additional features or
2025-08-26T19:31:42.9617850Z experiments which the user could be opted in to.
2025-08-26T19:31:42.9618482Z 
2025-08-26T19:31:42.9619023Z The user list has the following rules:
2025-08-26T19:31:42.9619623Z 
2025-08-26T19:31:42.9620277Z - Users are GitHub usernames, which must start with the @ prefix
2025-08-26T19:31:42.9621185Z - Each user is also a comma-separated list of features/experiments to enable
2025-08-26T19:31:42.9622135Z - A "#" prefix opts the user out of all experiments
