2025-08-26T19:31:43.5566039Z This runner determinator is used to determine which set of runners to run a
2025-08-26T19:31:43.5567092Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-08-26T19:31:43.5568338Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-08-26T19:31:43.5569318Z of which runners should be used to run which job.
2025-08-26T19:31:43.5570020Z 
2025-08-26T19:31:43.5570811Z The configuration has two parts, the settings and a list of opted-in users,
2025-08-26T19:31:43.5571859Z separated by a line containing "---".  If the line is not present, the
2025-08-26T19:31:43.5572919Z settings are considered to be empty with only the second part, the user
2025-08-26T19:31:43.5573852Z list, defined.
2025-08-26T19:31:43.5574353Z 
2025-08-26T19:31:43.5575174Z The first part is a YAML block that defines the rollout settings. This can be
2025-08-26T19:31:43.5576273Z used to define any settings that are needed to determine which runners to use.
2025-08-26T19:31:43.5577303Z It's fields are defined by the RolloutSettings class below.
2025-08-26T19:31:43.5578051Z 
2025-08-26T19:31:43.5579063Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-08-26T19:31:43.5580141Z The user list is also a comma separated list of additional features or
2025-08-26T19:31:43.5581027Z experiments which the user could be opted in to.
2025-08-26T19:31:43.5581761Z 
2025-08-26T19:31:43.5582269Z The user list has the following rules:
2025-08-26T19:31:43.5582917Z 
2025-08-26T19:31:43.5583669Z - Users are GitHub usernames, which must start with the @ prefix
2025-08-26T19:31:43.5584696Z - Each user is also a comma-separated list of features/experiments to enable
2025-08-26T19:31:43.5585966Z - A "#" prefix opts the user out of all experiments
2025-08-26T19:31:43.5586605Z 
2025-08-26T19:31:43.5587168Z Example config:
