2025-10-10T00:01:09.5474257Z This runner determinator is used to determine which set of runners to run a
2025-10-10T00:01:09.5475305Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-10-10T00:01:09.5476566Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-10-10T00:01:09.5477597Z of which runners should be used to run which job.
2025-10-10T00:01:09.5478291Z 
2025-10-10T00:01:09.5479080Z The configuration has two parts, the settings and a list of opted-in users,
2025-10-10T00:01:09.5480159Z separated by a line containing "---".  If the line is not present, the
2025-10-10T00:01:09.5481168Z settings are considered to be empty with only the second part, the user
2025-10-10T00:01:09.5482109Z list, defined.
2025-10-10T00:01:09.5482956Z 
2025-10-10T00:01:09.5483665Z The first part is a YAML block that defines the rollout settings. This can be
2025-10-10T00:01:09.5484874Z used to define any settings that are needed to determine which runners to use.
2025-10-10T00:01:09.5485852Z It's fields are defined by the RolloutSettings class below.
2025-10-10T00:01:09.5486603Z 
2025-10-10T00:01:09.5487691Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-10-10T00:01:09.5488726Z The user list is also a comma separated list of additional features or
2025-10-10T00:01:09.5489645Z experiments which the user could be opted in to.
2025-10-10T00:01:09.5490366Z 
2025-10-10T00:01:09.5490927Z The user list has the following rules:
2025-10-10T00:01:09.5491537Z 
2025-10-10T00:01:09.5573403Z - Users are GitHub usernames, which must start with the @ prefix
2025-10-10T00:01:09.5574536Z - Each user is also a comma-separated list of features/experiments to enable
2025-10-10T00:01:09.5575412Z - A "#" prefix opts the user out of all experiments
2025-10-10T00:01:09.5576011Z 
2025-10-10T00:01:09.5576397Z Example config:
