2025-11-03T15:43:06.7512969Z This runner determinator is used to determine which set of runners to run a
2025-11-03T15:43:06.7514797Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-11-03T15:43:06.7516169Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-11-03T15:43:06.7517185Z of which runners should be used to run which job.
2025-11-03T15:43:06.7517941Z 
2025-11-03T15:43:06.7518669Z The configuration has two parts, the settings and a list of opted-in users,
2025-11-03T15:43:06.7519777Z separated by a line containing "---".  If the line is not present, the
2025-11-03T15:43:06.7520886Z settings are considered to be empty with only the second part, the user
2025-11-03T15:43:06.7521737Z list, defined.
2025-11-03T15:43:06.7522390Z 
2025-11-03T15:43:06.7523287Z The first part is a YAML block that defines the rollout settings. This can be
2025-11-03T15:43:06.7524599Z used to define any settings that are needed to determine which runners to use.
2025-11-03T15:43:06.7525610Z It's fields are defined by the RolloutSettings class below.
2025-11-03T15:43:06.7526358Z 
2025-11-03T15:43:06.7527455Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-11-03T15:43:06.7528490Z The user list is also a comma separated list of additional features or
2025-11-03T15:43:06.7529404Z experiments which the user could be opted in to.
2025-11-03T15:43:06.7530150Z 
2025-11-03T15:43:06.7530676Z The user list has the following rules:
2025-11-03T15:43:06.7531307Z 
2025-11-03T15:43:06.7532068Z - Users are GitHub usernames, which must start with the @ prefix
2025-11-03T15:43:06.7533331Z - Each user is also a comma-separated list of features/experiments to enable
2025-11-03T15:43:06.7534307Z - A "#" prefix opts the user out of all experiments
2025-11-03T15:43:06.7535071Z 
2025-11-03T15:43:06.7535523Z Example config:
