2025-07-17T06:33:19.5461903Z This runner determinator is used to determine which set of runners to run a
2025-07-17T06:33:19.5463155Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-07-17T06:33:19.5464385Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-07-17T06:33:19.5465628Z of which runners should be used to run which job.
2025-07-17T06:33:19.5466350Z 
2025-07-17T06:33:19.5467038Z The configuration has two parts, the settings and a list of opted-in users,
2025-07-17T06:33:19.5468025Z separated by a line containing "---".  If the line is not present, the
2025-07-17T06:33:19.5469040Z settings are considered to be empty with only the second part, the user
2025-07-17T06:33:19.5469905Z list, defined.
2025-07-17T06:33:19.5470424Z 
2025-07-17T06:33:19.5471376Z The first part is a YAML block that defines the rollout settings. This can be
2025-07-17T06:33:19.5472465Z used to define any settings that are needed to determine which runners to use.
2025-07-17T06:33:19.5473391Z It's fields are defined by the RolloutSettings class below.
2025-07-17T06:33:19.5474400Z 
2025-07-17T06:33:19.5475265Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-07-17T06:33:19.5476259Z The user list is also a comma separated list of additional features or
2025-07-17T06:33:19.5477182Z experiments which the user could be opted in to.
2025-07-17T06:33:19.5477809Z 
2025-07-17T06:33:19.5478299Z The user list has the following rules:
2025-07-17T06:33:19.5478901Z 
2025-07-17T06:33:19.5479571Z - Users are GitHub usernames, which must start with the @ prefix
2025-07-17T06:33:19.5480486Z - Each user is also a comma-separated list of features/experiments to enable
2025-07-17T06:33:19.5481398Z - A "#" prefix opts the user out of all experiments
2025-07-17T06:33:19.5482064Z
