2025-08-26T19:39:34.2136481Z This runner determinator is used to determine which set of runners to run a
2025-08-26T19:39:34.2137531Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-08-26T19:39:34.2138785Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-08-26T19:39:34.2139787Z of which runners should be used to run which job.
2025-08-26T19:39:34.2140491Z 
2025-08-26T19:39:34.2141552Z The configuration has two parts, the settings and a list of opted-in users,
2025-08-26T19:39:34.2142650Z separated by a line containing "---".  If the line is not present, the
2025-08-26T19:39:34.2143698Z settings are considered to be empty with only the second part, the user
2025-08-26T19:39:34.2144680Z list, defined.
2025-08-26T19:39:34.2145187Z 
2025-08-26T19:39:34.2145886Z The first part is a YAML block that defines the rollout settings. This can be
2025-08-26T19:39:34.2147024Z used to define any settings that are needed to determine which runners to use.
2025-08-26T19:39:34.2148057Z It's fields are defined by the RolloutSettings class below.
2025-08-26T19:39:34.2148798Z 
2025-08-26T19:39:34.2149907Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-08-26T19:39:34.2151173Z The user list is also a comma separated list of additional features or
2025-08-26T19:39:34.2152084Z experiments which the user could be opted in to.
2025-08-26T19:39:34.2152860Z 
2025-08-26T19:39:34.2153392Z The user list has the following rules:
2025-08-26T19:39:34.2154012Z 
2025-08-26T19:39:34.2154812Z - Users are GitHub usernames, which must start with the @ prefix
2025-08-26T19:39:34.2155833Z - Each user is also a comma-separated list of features/experiments to enable
2025-08-26T19:39:34.2156775Z - A "#" prefix opts the user out of all experiments
2025-08-26T19:39:34.2157477Z
