2025-08-14T20:43:47.3506035Z This runner determinator is used to determine which set of runners to run a
2025-08-14T20:43:47.3507087Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-08-14T20:43:47.3508259Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-08-14T20:43:47.3509175Z of which runners should be used to run which job.
2025-08-14T20:43:47.3509884Z 
2025-08-14T20:43:47.3510594Z The configuration has two parts, the settings and a list of opted-in users,
2025-08-14T20:43:47.3511551Z separated by a line containing "---".  If the line is not present, the
2025-08-14T20:43:47.3512607Z settings are considered to be empty with only the second part, the user
2025-08-14T20:43:47.3513429Z list, defined.
2025-08-14T20:43:47.3513884Z 
2025-08-14T20:43:47.3514597Z The first part is a YAML block that defines the rollout settings. This can be
2025-08-14T20:43:47.3515936Z used to define any settings that are needed to determine which runners to use.
2025-08-14T20:43:47.3516938Z It's fields are defined by the RolloutSettings class below.
2025-08-14T20:43:47.3517949Z 
2025-08-14T20:43:47.3518644Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-08-14T20:43:47.3519681Z The user list is also a comma separated list of additional features or
2025-08-14T20:43:47.3520543Z experiments which the user could be opted in to.
2025-08-14T20:43:47.3521205Z 
2025-08-14T20:43:47.3521788Z The user list has the following rules:
2025-08-14T20:43:47.3522359Z 
2025-08-14T20:43:47.3523019Z - Users are GitHub usernames, which must start with the @ prefix
2025-08-14T20:43:47.3523985Z - Each user is also a comma-separated list of features/experiments to enable
2025-08-14T20:43:47.3524887Z - A "#" prefix opts the user out of all experiments
