2025-11-03T15:43:04.9004436Z This runner determinator is used to determine which set of runners to run a
2025-11-03T15:43:04.9005684Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-11-03T15:43:04.9006895Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-11-03T15:43:04.9007872Z of which runners should be used to run which job.
2025-11-03T15:43:04.9008565Z 
2025-11-03T15:43:04.9009219Z The configuration has two parts, the settings and a list of opted-in users,
2025-11-03T15:43:04.9010289Z separated by a line containing "---".  If the line is not present, the
2025-11-03T15:43:04.9011307Z settings are considered to be empty with only the second part, the user
2025-11-03T15:43:04.9012115Z list, defined.
2025-11-03T15:43:04.9012672Z 
2025-11-03T15:43:04.9013326Z The first part is a YAML block that defines the rollout settings. This can be
2025-11-03T15:43:04.9014402Z used to define any settings that are needed to determine which runners to use.
2025-11-03T15:43:04.9015763Z It's fields are defined by the RolloutSettings class below.
2025-11-03T15:43:04.9016726Z 
2025-11-03T15:43:04.9017454Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-11-03T15:43:04.9018402Z The user list is also a comma separated list of additional features or
2025-11-03T15:43:04.9019376Z experiments which the user could be opted in to.
2025-11-03T15:43:04.9020037Z 
2025-11-03T15:43:04.9021014Z The user list has the following rules:
2025-11-03T15:43:04.9022242Z 
2025-11-03T15:43:04.9022940Z - Users are GitHub usernames, which must start with the @ prefix
2025-11-03T15:43:04.9023896Z - Each user is also a comma-separated list of features/experiments to enable
2025-11-03T15:43:04.9025073Z - A "#" prefix opts the user out of all experiments
2025-11-03T15:43:04.9025786Z
