Your quant team ingests daily satellite parking-lot counts for retail names. Which data infrastructure control is MOST critical before promoting the feed to production alpha?
Select an answer to reveal the explanation.
Short Explanation
Alt-data dies in production without PIT availability times, SLA watches, and coverage metadata.
Full Explanation
Satellite and other alt-data feeds require rigorous point-in-time semantics (when was the observation knowable?), coverage bias controls, and operational monitoring. Overwriting history destroys research reproducibility.
