Validate Pipeline

End-to-end validation of the UNS pipeline. Queries TimescaleDB to verify that readings collected by the clients landed correctly in tag_history.

Usage

• /validate-pipeline — query TimescaleDB and report on the data that landed

Prerequisites

Before running, ensure:

1. Dependencies installed: uv sync
2. The schema is applied and uns_namespace is seeded
3. The collection clients have run, so tag_history holds data

To collect without real sources, start the simulator first (a separate script). If tag_history is empty, the validation script warns and exits.
