2025-07-17T06:38:24.0115975Z This runner determinator is used to determine which set of runners to run a
2025-07-17T06:38:24.0117849Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-07-17T06:38:24.0119987Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-07-17T06:38:24.0121647Z of which runners should be used to run which job.
2025-07-17T06:38:24.0122939Z 
2025-07-17T06:38:24.0124170Z The configuration has two parts, the settings and a list of opted-in users,
2025-07-17T06:38:24.0126057Z separated by a line containing "---".  If the line is not present, the
2025-07-17T06:38:24.0128168Z settings are considered to be empty with only the second part, the user
2025-07-17T06:38:24.0129684Z list, defined.
2025-07-17T06:38:24.0130664Z 
2025-07-17T06:38:24.0131765Z The first part is a YAML block that defines the rollout settings. This can be
2025-07-17T06:38:24.0133721Z used to define any settings that are needed to determine which runners to use.
2025-07-17T06:38:24.0135422Z It's fields are defined by the RolloutSettings class below.
2025-07-17T06:38:24.0136753Z 
2025-07-17T06:38:24.0138574Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-07-17T06:38:24.0140357Z The user list is also a comma separated list of additional features or
2025-07-17T06:38:24.0141998Z experiments which the user could be opted in to.
2025-07-17T06:38:24.0143195Z 
2025-07-17T06:38:24.0144073Z The user list has the following rules:
2025-07-17T06:38:24.0145208Z 
2025-07-17T06:38:24.0146332Z - Users are GitHub usernames, which must start with the @ prefix
2025-07-17T06:38:24.0148313Z - Each user is also a comma-separated list of features/experiments to enable
2025-07-17T06:38:24.0150037Z - A "#" prefix opts the user out of all experiments
