2025-06-01T20:56:26.1352866Z This runner determinator is used to determine which set of runners to run a
2025-06-01T20:56:26.1354142Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-06-01T20:56:26.1355386Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-06-01T20:56:26.1356412Z of which runners should be used to run which job.
2025-06-01T20:56:26.1357142Z 
2025-06-01T20:56:26.1357850Z The configuration has two parts, the settings and a list of opted-in users,
2025-06-01T20:56:26.1358976Z separated by a line containing "---".  If the line is not present, the
2025-06-01T20:56:26.1360064Z settings are considered to be empty with only the second part, the user
2025-06-01T20:56:26.1360932Z list, defined.
2025-06-01T20:56:26.1361514Z 
2025-06-01T20:56:26.1362214Z The first part is a YAML block that defines the rollout settings. This can be
2025-06-01T20:56:26.1363317Z used to define any settings that are needed to determine which runners to use.
2025-06-01T20:56:26.1364594Z It's fields are defined by the RolloutSettings class below.
2025-06-01T20:56:26.1365352Z 
2025-06-01T20:56:26.1366119Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-06-01T20:56:26.1367146Z The user list is also a comma separated list of additional features or
2025-06-01T20:56:26.1368139Z experiments which the user could be opted in to.
2025-06-01T20:56:26.1368851Z 
2025-06-01T20:56:26.1369380Z The user list has the following rules:
2025-06-01T20:56:26.1370107Z 
2025-06-01T20:56:26.1370792Z - Users are GitHub usernames, which must start with the @ prefix
2025-06-01T20:56:26.1371806Z - Each user is also a comma-separated list of features/experiments to enable
2025-06-01T20:56:26.1372824Z - A "#" prefix opts the user out of all experiments
2025-06-01T20:56:26.1374064Z 
2025-06-01T20:56:26.1374690Z Example config:
2025-06-01T20:56:26.1375459Z     # A list of experiments that can be opted into.
2025-06-01T20:56:26.1376416Z     # This defines the behavior they'll induce when opted into.
2025-06-01T20:56:26.1377260Z     # Expected syntax is:
