2025-09-07T07:03:23.8135961Z This runner determinator is used to determine which set of runners to run a
2025-09-07T07:03:23.8136985Z GitHub job on. It uses the first comment of a GitHub issue (by default
2025-09-07T07:03:23.8138257Z https://github.com/pytorch/test-infra/issues/5132) to define the configuration
2025-09-07T07:03:23.8139243Z of which runners should be used to run which job.
2025-09-07T07:03:23.8139921Z 
2025-09-07T07:03:23.8140674Z The configuration has two parts, the settings and a list of opted-in users,
2025-09-07T07:03:23.8141761Z separated by a line containing "---".  If the line is not present, the
2025-09-07T07:03:23.8142909Z settings are considered to be empty with only the second part, the user
2025-09-07T07:03:23.8143804Z list, defined.
2025-09-07T07:03:23.8144386Z 
2025-09-07T07:03:23.8145064Z The first part is a YAML block that defines the rollout settings. This can be
2025-09-07T07:03:23.8146220Z used to define any settings that are needed to determine which runners to use.
2025-09-07T07:03:23.8147236Z It's fields are defined by the RolloutSettings class below.
2025-09-07T07:03:23.8147946Z 
2025-09-07T07:03:23.8149014Z The second part is a list of users who are explicitly opted in to the LF fleet.
2025-09-07T07:03:23.8150041Z The user list is also a comma separated list of additional features or
2025-09-07T07:03:23.8150970Z experiments which the user could be opted in to.
2025-09-07T07:03:23.8151724Z 
2025-09-07T07:03:23.8152240Z The user list has the following rules:
2025-09-07T07:03:23.8153126Z 
2025-09-07T07:03:23.8153868Z - Users are GitHub usernames, which must start with the @ prefix
2025-09-07T07:03:23.8154930Z - Each user is also a comma-separated list of features/experiments to enable
2025-09-07T07:03:23.8155826Z - A "#" prefix opts the user out of all experiments
2025-09-07T07:03:23.8156543Z 
2025-09-07T07:03:23.8157054Z Example config:
