2025-10-10T00:01:08.8492512Z This runner determinator is used to determine which set of runners to run a
2025-10-10T00:01:08.8493620Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-10-10T00:01:08.8494829Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-10-10T00:01:08.8495955Z of which runners should be used to run which job.
2025-10-10T00:01:08.8496664Z 
2025-10-10T00:01:08.8497509Z The configuration has two parts, the settings and a list of opted-in users,
2025-10-10T00:01:08.8498615Z separated by a line containing "---".  If the line is not present, the
2025-10-10T00:01:08.8500308Z settings are considered to be empty with only the second part, the user
2025-10-10T00:01:08.8501298Z list, defined.
2025-10-10T00:01:08.8501859Z 
2025-10-10T00:01:08.8502605Z The first part is a YAML block that defines the rollout settings. This can be
2025-10-10T00:01:08.8503675Z used to define any settings that are needed to determine which runners to use.
2025-10-10T00:01:08.8504795Z It's fields are defined by the RolloutSettings class below.
2025-10-10T00:01:08.8505576Z 
2025-10-10T00:01:08.8506403Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-10-10T00:01:08.8507506Z The user list is also a comma separated list of additional features or
2025-10-10T00:01:08.8508431Z experiments which the user could be opted in to.
2025-10-10T00:01:08.8509231Z 
2025-10-10T00:01:08.8509950Z The user list has the following rules:
2025-10-10T00:01:08.8510610Z 
2025-10-10T00:01:08.8511439Z - Users are GitHub usernames, which must start with the @ prefix
2025-10-10T00:01:08.8512481Z - Each user is also a comma-separated list of features/experiments to enable
2025-10-10T00:01:08.8513464Z - A "#" prefix opts the user out of all experiments
