2025-06-01T20:56:27.7203605Z This runner determinator is used to determine which set of runners to run a
2025-06-01T20:56:27.7204626Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-06-01T20:56:27.7205802Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-06-01T20:56:27.7206711Z of which runners should be used to run which job.
2025-06-01T20:56:27.7207413Z 
2025-06-01T20:56:27.7208083Z The configuration has two parts, the settings and a list of opted-in users,
2025-06-01T20:56:27.7209075Z separated by a line containing "---".  If the line is not present, the
2025-06-01T20:56:27.7210118Z settings are considered to be empty with only the second part, the user
2025-06-01T20:56:27.7210912Z list, defined.
2025-06-01T20:56:27.7211376Z 
2025-06-01T20:56:27.7212088Z The first part is a YAML block that defines the rollout settings. This can be
2025-06-01T20:56:27.7213473Z used to define any settings that are needed to determine which runners to use.
2025-06-01T20:56:27.7214457Z It's fields are defined by the RolloutSettings class below.
2025-06-01T20:56:27.7215252Z 
2025-06-01T20:56:27.7215904Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-06-01T20:56:27.7216872Z The user list is also a comma separated list of additional features or
2025-06-01T20:56:27.7217771Z experiments which the user could be opted in to.
2025-06-01T20:56:27.7218429Z 
2025-06-01T20:56:27.7218919Z The user list has the following rules:
2025-06-01T20:56:27.7219586Z 
2025-06-01T20:56:27.7220461Z - Users are GitHub usernames, which must start with the @ prefix
2025-06-01T20:56:27.7221368Z - Each user is also a comma-separated list of features/experiments to enable
2025-06-01T20:56:27.7222639Z - A "#" prefix opts the user out of all experiments
2025-06-01T20:56:27.7223557Z 
2025-06-01T20:56:27.7224036Z Example config:
