Files are limited to 50 MB unless the deployment says otherwise. Answers `201` with the artifact's id and a download link. Daemon push: requires the daemon's realm token (`cliq_dt_…`) for the realm that owns the run given by `run_id`. ## OpenAPI ````yaml /openapi/hub-by-tag/hub-artifacts.yaml post /v1/artifacts/submit openapi: 3.0.3 info: title: 'CliqHub API: Artifacts' version: 1.0.0 description: >- Files a run produced (reports, patches, screenshots), stored by CliqHub, and the run's records (phase outputs, transcripts).
