If you see the job owner changing after an Asset Bundle deploy, it’s because ownership defaults to the principal that performs the deployment (the PAT/SPN used by the CLI). To keep ownership stable, deploy with a dedicated service principal and set it explicitly in the bundle: add a permissions block on the job giving that SPN (or a group) the role IS_OWNER, and use run_as so the job executes under the same identity. Avoid ad-hoc edits in the UI—saving changes there will flip ownership to the editor. In short: pin owner via permissions.IS_OWNER, run the job via run_as, and perform all deployments with the same SPN to prevent owner drift.
