# Task progress

The Quantization and Evaluation queues show Azure DevOps pipeline-step progress.
The dispatcher fetches the Build Timeline API for active runs every 60 seconds,
using the existing server-side `AZP_DEVOPS_PAT`. The queue UI refreshes every five
seconds and reads an in-memory snapshot; browser refreshes do not call Azure.
The app and dispatcher must run in the same process (as with `python app.py`).

The bar counts completed Task records, including skipped steps, and displays the
currently running task names. It measures pipeline steps, not elapsed time,
AutoRound iterations, or evaluation samples. Steps can differ substantially in
duration. Retried steps use their latest attempt. Snapshots older than three
minutes are no longer displayed; missing credentials, unavailable timelines, and
API failures produce an indeterminate bar with “Waiting for progress information”.

For iteration/sample percentages, the external quantization/evaluation runner
must additionally expose structured progress (completed units, total units,
stage, run ID, and timestamp), through an authenticated endpoint or status artifact.
The current integration requires no changes to that runner.
