2025-09-07T07:02:11.1632761Z This runner determinator is used to determine which set of runners to run a
2025-09-07T07:02:11.1633843Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-09-07T07:02:11.1635099Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-09-07T07:02:11.1636253Z of which runners should be used to run which job.
2025-09-07T07:02:11.1636969Z 
2025-09-07T07:02:11.1637755Z The configuration has two parts, the settings and a list of opted-in users,
2025-09-07T07:02:11.1638873Z separated by a line containing "---".  If the line is not present, the
2025-09-07T07:02:11.1639899Z settings are considered to be empty with only the second part, the user
2025-09-07T07:02:11.1640824Z list, defined.
2025-09-07T07:02:11.1641352Z 
2025-09-07T07:02:11.1642062Z The first part is a YAML block that defines the rollout settings. This can be
2025-09-07T07:02:11.1643125Z used to define any settings that are needed to determine which runners to use.
2025-09-07T07:02:11.1644219Z It's fields are defined by the RolloutSettings class below.
2025-09-07T07:02:11.1644968Z 
2025-09-07T07:02:11.1646215Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-09-07T07:02:11.1647452Z The user list is also a comma separated list of additional features or
2025-09-07T07:02:11.1648349Z experiments which the user could be opted in to.
2025-09-07T07:02:11.1649043Z 
2025-09-07T07:02:11.1649639Z The user list has the following rules:
2025-09-07T07:02:11.1650260Z 
2025-09-07T07:02:11.1650979Z - Users are GitHub usernames, which must start with the @ prefix
2025-09-07T07:02:11.1652048Z - Each user is also a comma-separated list of features/experiments to enable
2025-09-07T07:02:11.1652991Z - A "#" prefix opts the user out of all experiments
2025-09-07T07:02:11.1653639Z 
2025-09-07T07:02:11.1654177Z Example config:
2025-09-07T07:02:11.1654858Z     # A list of experiments that can be opted into.
2025-09-07T07:02:11.1655860Z     # This defines the behavior they'll induce when opted into.
2025-09-07T07:02:11.1656733Z     # Expected syntax is:
