2025-12-04T08:52:15.0030111Z This runner determinator is used to determine which set of runners to run a
2025-12-04T08:52:15.0031159Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-12-04T08:52:15.0032589Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-12-04T08:52:15.0033603Z of which runners should be used to run which job.
2025-12-04T08:52:15.0034380Z 
2025-12-04T08:52:15.0035146Z The configuration has two parts, the settings and a list of opted-in users,
2025-12-04T08:52:15.0036224Z separated by a line containing "---".  If the line is not present, the
2025-12-04T08:52:15.0037365Z settings are considered to be empty with only the second part, the user
2025-12-04T08:52:15.0038210Z list, defined.
2025-12-04T08:52:15.0038803Z 
2025-12-04T08:52:15.0039520Z The first part is a YAML block that defines the rollout settings. This can be
2025-12-04T08:52:15.0040909Z used to define any settings that are needed to determine which runners to use.
2025-12-04T08:52:15.0041955Z It's fields are defined by the RolloutSettings class below.
2025-12-04T08:52:15.0042737Z 
2025-12-04T08:52:15.0043774Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-12-04T08:52:15.0044812Z The user list is also a comma separated list of additional features or
2025-12-04T08:52:15.0045808Z experiments which the user could be opted in to.
2025-12-04T08:52:15.0046540Z 
2025-12-04T08:52:15.0047045Z The user list has the following rules:
2025-12-04T08:52:15.0047738Z 
2025-12-04T08:52:15.0048448Z - Users are GitHub usernames, which must start with the @ prefix
2025-12-04T08:52:15.0049502Z - Each user is also a comma-separated list of features/experiments to enable
2025-12-04T08:52:15.0050950Z - A "#" prefix opts the user out of all experiments
2025-12-04T08:52:15.0051648Z 
2025-12-04T08:52:15.0052151Z Example config:
