2025-09-07T06:09:27.6553687Z This runner determinator is used to determine which set of runners to run a
2025-09-07T06:09:27.6555319Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-09-07T06:09:27.6557394Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-09-07T06:09:27.6558979Z of which runners should be used to run which job.
2025-09-07T06:09:27.6560103Z 
2025-09-07T06:09:27.6561427Z The configuration has two parts, the settings and a list of opted-in users,
2025-09-07T06:09:27.6563376Z separated by a line containing "---".  If the line is not present, the
2025-09-07T06:09:27.6565429Z settings are considered to be empty with only the second part, the user
2025-09-07T06:09:27.6566909Z list, defined.
2025-09-07T06:09:27.6567784Z 
2025-09-07T06:09:27.6568889Z The first part is a YAML block that defines the rollout settings. This can be
2025-09-07T06:09:27.6570780Z used to define any settings that are needed to determine which runners to use.
2025-09-07T06:09:27.6572729Z It's fields are defined by the RolloutSettings class below.
2025-09-07T06:09:27.6573878Z 
2025-09-07T06:09:27.6575192Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-09-07T06:09:27.6576880Z The user list is also a comma separated list of additional features or
2025-09-07T06:09:27.6578323Z experiments which the user could be opted in to.
2025-09-07T06:09:27.6579506Z 
2025-09-07T06:09:27.6580291Z The user list has the following rules:
2025-09-07T06:09:27.6581364Z 
2025-09-07T06:09:27.6582648Z - Users are GitHub usernames, which must start with the @ prefix
2025-09-07T06:09:27.6584325Z - Each user is also a comma-separated list of features/experiments to enable
2025-09-07T06:09:27.6585905Z - A "#" prefix opts the user out of all experiments
