Editorial policy and data provenance

nichelib is a data compiler. Our editorial standard is traceability, not opinion.

Provenance standard

Every populated value in a licensed bundle carries a source URL, a verbatim quote, a fetch timestamp and a confidence level. A claim without a source quote is not published. Numbers and table cells are extracted from the source text rather than inferred from marketing copy.

QA gate

Each bundle passes a blocking quality gate on model count, unique identifiers, provenance coverage, price coverage and spec-row coverage; the tier and coverage are stated on the dataset page and in the dataset card. Values that look inconsistent (for example, advertised Watt-hours that do not match voltage times capacity) are flagged rather than silently corrected.

Corrections

Corrections with a source URL are folded into the next refresh and appear in the public change log. The compiled byline for a dataset is the nichelib data team; there are no invented authors or reviews.
