Get a single deployment record

A single deployment history record.

A deployment targets exactly one of training_job_id or base_model: the trained adapter that was activated, or the base catalog model that was activated when no adapter is in use.

Attributes: id: Unique deployment record ID. project_id: The project whose active model was changed. training_job_id: Training job that was deployed (training-job shape). base_model: HuggingFace base model ID that was deployed (base-model shape). deployed_by: User ID who triggered the deployment. reason: Optional reason for the swap. deployed_at: When the swap occurred. experiment_id: Experiment whose agent promoted, when one did. finetune_plan_id: Plan revision that authorised the promotion. selection_evaluation_run_id: Evaluation Suite run the promotion was decided on. recipe_fingerprint: Digest of the promoted candidate's recipe.

The four evidence fields are null for a promotion nobody recorded evidence for -- a human pressing promote, or the post-training auto-deploy. They are returned so the basis for a swap is readable after the fact rather than only at the moment it happens.
