2025-12-04T08:11:25.7540857Z This runner determinator is used to determine which set of runners to run a
2025-12-04T08:11:25.7541891Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-12-04T08:11:25.7543027Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-12-04T08:11:25.7544043Z of which runners should be used to run which job.
2025-12-04T08:11:25.7544964Z 
2025-12-04T08:11:25.7545679Z The configuration has two parts, the settings and a list of opted-in users,
2025-12-04T08:11:25.7546780Z separated by a line containing "---".  If the line is not present, the
2025-12-04T08:11:25.7547774Z settings are considered to be empty with only the second part, the user
2025-12-04T08:11:25.7548604Z list, defined.
2025-12-04T08:11:25.7549127Z 
2025-12-04T08:11:25.7549815Z The first part is a YAML block that defines the rollout settings. This can be
2025-12-04T08:11:25.7550874Z used to define any settings that are needed to determine which runners to use.
2025-12-04T08:11:25.7551887Z It's fields are defined by the RolloutSettings class below.
2025-12-04T08:11:25.7552620Z 
2025-12-04T08:11:25.7553516Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-12-04T08:11:25.7554662Z The user list is also a comma separated list of additional features or
2025-12-04T08:11:25.7555559Z experiments which the user could be opted in to.
2025-12-04T08:11:25.7556213Z 
2025-12-04T08:11:25.7556752Z The user list has the following rules:
2025-12-04T08:11:25.7557351Z 
2025-12-04T08:11:25.7558040Z - Users are GitHub usernames, which must start with the @ prefix
2025-12-04T08:11:25.7559025Z - Each user is also a comma-separated list of features/experiments to enable
2025-12-04T08:11:25.7559956Z - A "#" prefix opts the user out of all experiments
2025-12-04T08:11:25.7560626Z 
2025-12-04T08:11:25.7561080Z Example config:
