Overview

Delivery flow date, clearing date, product, and source update are preserved independently. Each price applies to the source's delivery block.

Query contract

Preserve one canonical row per (flow_date, product, source_updated_at, observed_at) before aggregating.

Analysis rules

  • Each changed file is an acquisition snapshot. Use FINAL, select one latest observed_at per source_url at or before the ATG knowledge cutoff, then read only rows in that snapshot. Within it select the latest source_updated_at per native delivery identity. This preserves removed rows as history rather than carrying them into a newer publication. source_updated_at separately bounds publisher knowledge; historical acquisition is retrospective.
  • Keep Firm-LD and Recall separate. Native identity is (flow_date, product). Never expand a daily block price into 24 hourly prices or compare it directly with an unmatched hourly price.

Interpretation

  • flow_date is a source date label, not UTC midnight or a verified delivery-block boundary. The collection starts January 4, 2010; earlier daily products use a different basis.
