2025-07-17T06:33:20.3252237Z This runner determinator is used to determine which set of runners to run a
2025-07-17T06:33:20.3253219Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-07-17T06:33:20.3254425Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-07-17T06:33:20.3255559Z of which runners should be used to run which job.
2025-07-17T06:33:20.3256231Z 
2025-07-17T06:33:20.3256913Z The configuration has two parts, the settings and a list of opted-in users,
2025-07-17T06:33:20.3257971Z separated by a line containing "---".  If the line is not present, the
2025-07-17T06:33:20.3258970Z settings are considered to be empty with only the second part, the user
2025-07-17T06:33:20.3260078Z list, defined.
2025-07-17T06:33:20.3261004Z 
2025-07-17T06:33:20.3261872Z The first part is a YAML block that defines the rollout settings. This can be
2025-07-17T06:33:20.3262879Z used to define any settings that are needed to determine which runners to use.
2025-07-17T06:33:20.3263925Z It's fields are defined by the RolloutSettings class below.
2025-07-17T06:33:20.3265030Z 
2025-07-17T06:33:20.3265729Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-07-17T06:33:20.3266814Z The user list is also a comma separated list of additional features or
2025-07-17T06:33:20.3267653Z experiments which the user could be opted in to.
2025-07-17T06:33:20.3268314Z 
2025-07-17T06:33:20.3268805Z The user list has the following rules:
2025-07-17T06:33:20.3269467Z 
2025-07-17T06:33:20.3270054Z - Users are GitHub usernames, which must start with the @ prefix
2025-07-17T06:33:20.3271047Z - Each user is also a comma-separated list of features/experiments to enable
2025-07-17T06:33:20.3271958Z - A "#" prefix opts the user out of all experiments
