2025-08-14T20:50:54.2396234Z This runner determinator is used to determine which set of runners to run a
2025-08-14T20:50:54.2397362Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-08-14T20:50:54.2398586Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-08-14T20:50:54.2399608Z of which runners should be used to run which job.
2025-08-14T20:50:54.2400337Z 
2025-08-14T20:50:54.2401042Z The configuration has two parts, the settings and a list of opted-in users,
2025-08-14T20:50:54.2402152Z separated by a line containing "---".  If the line is not present, the
2025-08-14T20:50:54.2403222Z settings are considered to be empty with only the second part, the user
2025-08-14T20:50:54.2404065Z list, defined.
2025-08-14T20:50:54.2404636Z 
2025-08-14T20:50:54.2405572Z The first part is a YAML block that defines the rollout settings. This can be
2025-08-14T20:50:54.2406725Z used to define any settings that are needed to determine which runners to use.
2025-08-14T20:50:54.2407798Z It's fields are defined by the RolloutSettings class below.
2025-08-14T20:50:54.2408545Z 
2025-08-14T20:50:54.2409564Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-08-14T20:50:54.2410576Z The user list is also a comma separated list of additional features or
2025-08-14T20:50:54.2411588Z experiments which the user could be opted in to.
2025-08-14T20:50:54.2412273Z 
2025-08-14T20:50:54.2412794Z The user list has the following rules:
2025-08-14T20:50:54.2413502Z 
2025-08-14T20:50:54.2414173Z - Users are GitHub usernames, which must start with the @ prefix
2025-08-14T20:50:54.2415419Z - Each user is also a comma-separated list of features/experiments to enable
2025-08-14T20:50:54.2416439Z - A "#" prefix opts the user out of all experiments
