Raw observations
Immutable, compressed JSONL snapshots preserve product identity, catalog attributes, price, availability, source, and observation time.
Derived intelligence
Adjacent snapshots produce movements, churn, trends, volatility, promotions, and conservative robust outlier flags.
Safety before publication
Robots rules, minimum coverage, valid-price, overlap, and product-count gates prevent partial crawls from replacing a healthy baseline.
Open methodology
The repository includes its schema, limitations, tests, workflow, and machine-readable weekly summary. No account credentials or private APIs are used.
