2025-10-10T00:01:08.8284215Z This runner determinator is used to determine which set of runners to run a
2025-10-10T00:01:08.8285240Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-10-10T00:01:08.8286483Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-10-10T00:01:08.8287465Z of which runners should be used to run which job.
2025-10-10T00:01:08.8288181Z 
2025-10-10T00:01:08.8288939Z The configuration has two parts, the settings and a list of opted-in users,
2025-10-10T00:01:08.8290076Z separated by a line containing "---".  If the line is not present, the
2025-10-10T00:01:08.8291135Z settings are considered to be empty with only the second part, the user
2025-10-10T00:01:08.8291954Z list, defined.
2025-10-10T00:01:08.8292518Z 
2025-10-10T00:01:08.8293199Z The first part is a YAML block that defines the rollout settings. This can be
2025-10-10T00:01:08.8294299Z used to define any settings that are needed to determine which runners to use.
2025-10-10T00:01:08.8295339Z It's fields are defined by the RolloutSettings class below.
2025-10-10T00:01:08.8296056Z 
2025-10-10T00:01:08.8297023Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-10-10T00:01:08.8298041Z The user list is also a comma separated list of additional features or
2025-10-10T00:01:08.8298963Z experiments which the user could be opted in to.
2025-10-10T00:01:08.8300109Z 
2025-10-10T00:01:08.8300652Z The user list has the following rules:
2025-10-10T00:01:08.8301295Z 
2025-10-10T00:01:08.8301935Z - Users are GitHub usernames, which must start with the @ prefix
2025-10-10T00:01:08.8303023Z - Each user is also a comma-separated list of features/experiments to enable
2025-10-10T00:01:08.8303980Z - A "#" prefix opts the user out of all experiments
2025-10-10T00:01:08.8304625Z 
2025-10-10T00:01:08.8305152Z Example config:
