2025-11-03T15:43:04.7659609Z This runner determinator is used to determine which set of runners to run a
2025-11-03T15:43:04.7660643Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-11-03T15:43:04.7661786Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-11-03T15:43:04.7662962Z of which runners should be used to run which job.
2025-11-03T15:43:04.7663729Z 
2025-11-03T15:43:04.7664379Z The configuration has two parts, the settings and a list of opted-in users,
2025-11-03T15:43:04.7665381Z separated by a line containing "---".  If the line is not present, the
2025-11-03T15:43:04.7666682Z settings are considered to be empty with only the second part, the user
2025-11-03T15:43:04.7667490Z list, defined.
2025-11-03T15:43:04.7667979Z 
2025-11-03T15:43:04.7668820Z The first part is a YAML block that defines the rollout settings. This can be
2025-11-03T15:43:04.7669867Z used to define any settings that are needed to determine which runners to use.
2025-11-03T15:43:04.7670879Z It's fields are defined by the RolloutSettings class below.
2025-11-03T15:43:04.7671569Z 
2025-11-03T15:43:04.7672269Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-11-03T15:43:04.7673349Z The user list is also a comma separated list of additional features or
2025-11-03T15:43:04.7674296Z experiments which the user could be opted in to.
2025-11-03T15:43:04.7674959Z 
2025-11-03T15:43:04.7675400Z The user list has the following rules:
2025-11-03T15:43:04.7676110Z 
2025-11-03T15:43:04.7676698Z - Users are GitHub usernames, which must start with the @ prefix
2025-11-03T15:43:04.7677633Z - Each user is also a comma-separated list of features/experiments to enable
2025-11-03T15:43:04.7678587Z - A "#" prefix opts the user out of all experiments
