Get Dataset Progress

Get the processing status of datasets, together with in-flight progress. Same dataset/pipeline selection as **GET /v1/datasets/status**, but each status value is always an object {status, progress} instead of a bare status — a dedicated endpoint rather than a flag on /status, so neither endpoint's response shape ever depends on how it was called. ## Query Parameters - **dataset** (List[UUID]): Dataset UUIDs to check (from GET /api/v1/datasets). Omit to get status for all datasets you can read. - **pipeline** (List[str]): Pipeline names to check: 'add_pipeline', 'cognify_pipeline', or 'code_graph_pipeline' (code ingestion via remember content_type='code'). Omit to default to cognify_pipeline. ## Response - Single pipeline (default): {dataset_id: {status, progress}} - Multiple pipelines: {dataset_id: {pipeline_name: {status, progress}}} **progress** is `null` until the first in-flight progress tick, then an object with `completed_items`, `total_items`, and `current_stage` — present only while the pipeline is running; terminal runs (completed/ errored) do not carry a progress snapshot. ## Error Codes - **409 Conflict**: Error retrieving status (e.g. requesting a dataset you don't have read permission for)
