2025-08-14T20:43:47.4882396Z This runner determinator is used to determine which set of runners to run a
2025-08-14T20:43:47.4883452Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-08-14T20:43:47.4884626Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-08-14T20:43:47.4885582Z of which runners should be used to run which job.
2025-08-14T20:43:47.4886304Z 
2025-08-14T20:43:47.4886993Z The configuration has two parts, the settings and a list of opted-in users,
2025-08-14T20:43:47.4887997Z separated by a line containing "---".  If the line is not present, the
2025-08-14T20:43:47.4889073Z settings are considered to be empty with only the second part, the user
2025-08-14T20:43:47.4889864Z list, defined.
2025-08-14T20:43:47.4890509Z 
2025-08-14T20:43:47.4891239Z The first part is a YAML block that defines the rollout settings. This can be
2025-08-14T20:43:47.4892271Z used to define any settings that are needed to determine which runners to use.
2025-08-14T20:43:47.4893251Z It's fields are defined by the RolloutSettings class below.
2025-08-14T20:43:47.4893962Z 
2025-08-14T20:43:47.4894962Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-08-14T20:43:47.4895988Z The user list is also a comma separated list of additional features or
2025-08-14T20:43:47.4896876Z experiments which the user could be opted in to.
2025-08-14T20:43:47.4897621Z 
2025-08-14T20:43:47.4898083Z The user list has the following rules:
2025-08-14T20:43:47.4898728Z 
2025-08-14T20:43:47.4899360Z - Users are GitHub usernames, which must start with the @ prefix
2025-08-14T20:43:47.4900639Z - Each user is also a comma-separated list of features/experiments to enable
2025-08-14T20:43:47.4901621Z - A "#" prefix opts the user out of all experiments
