DATA INTELLIGENCE · RESEARCHER

Every number has a source. Every source has a date.

sourc.dev exists because cited AI data is rare. Most numbers in circulation are undated, unsourced, or based on aggregators who do not track their inputs. Every data point on sourc.dev has a primary source URL, a verification date, and a confidence level. If we cannot source it, we do not publish it.

What this view will show

Full attribute provenance — every verified attribute with source URL, verification date, and confidence level, formatted for citation
Quality gate status — which metrics are live, calibrating, and what the threshold criteria are, fully documented
Historical record — the append-only archive so you can cite what was true on a specific date, not just today
Methodology documentation — every formula, every version, every data source at /methodology
Integration graph provenance — every entity relation has a signal_url and signal_date confirming it existed

The data exists today

5,556 verified attributes — each has a source_url and verified_at timestamp. None estimated without disclosure.

2,625 rows in the append-only history layer. When a value changes, the old value is preserved with its original source and date.

173 tracked attribute types in the registry, each with documented definition, unit, and collection methodology.

Every metric passes through the quality gate before it is surfaced.
