2025-08-26T19:31:44.7070402Z This runner determinator is used to determine which set of runners to run a
2025-08-26T19:31:44.7071442Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-08-26T19:31:44.7072579Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-08-26T19:31:44.7073649Z of which runners should be used to run which job.
2025-08-26T19:31:44.7074286Z 
2025-08-26T19:31:44.7074981Z The configuration has two parts, the settings and a list of opted-in users,
2025-08-26T19:31:44.7076039Z separated by a line containing "---".  If the line is not present, the
2025-08-26T19:31:44.7077043Z settings are considered to be empty with only the second part, the user
2025-08-26T19:31:44.7077869Z list, defined.
2025-08-26T19:31:44.7078393Z 
2025-08-26T19:31:44.7079059Z The first part is a YAML block that defines the rollout settings. This can be
2025-08-26T19:31:44.7080186Z used to define any settings that are needed to determine which runners to use.
2025-08-26T19:31:44.7081230Z It's fields are defined by the RolloutSettings class below.
2025-08-26T19:31:44.7081939Z 
2025-08-26T19:31:44.7082853Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-08-26T19:31:44.7083927Z The user list is also a comma separated list of additional features or
2025-08-26T19:31:44.7084769Z experiments which the user could be opted in to.
2025-08-26T19:31:44.7085428Z 
2025-08-26T19:31:44.7085962Z The user list has the following rules:
2025-08-26T19:31:44.7086576Z 
2025-08-26T19:31:44.7087202Z - Users are GitHub usernames, which must start with the @ prefix
2025-08-26T19:31:44.7088172Z - Each user is also a comma-separated list of features/experiments to enable
2025-08-26T19:31:44.7089080Z - A "#" prefix opts the user out of all experiments
2025-08-26T19:31:44.7089684Z 
2025-08-26T19:31:44.7090398Z Example config:
