Public stats · source-derived
Source-derived measurements of the committed sports archive. These describe corpus scope and integrity, not traffic, popularity, or private user behavior.
Required identities represented
65,125
Of 65125 required source identities across NFL, NBA, MLB, NHL, and MLS
Every identity in the five currently committed source universes is represented. This is not a claim that every athlete or every statistic in sports history is complete.

Physical profiles integrity-checked
65,660
Of profile JSON records inspected by the current integrity gate
The latest structural audit found zero errors and 0 warnings. Physical profiles can exceed the strict universe because supplemental and disambiguated identities are retained.

Profiles with a fillable stat gap
6,246
Of player profiles across NFL, NBA, MLB, and NHL
The archive is broad but not statistically complete. These gaps stay visible so a large profile count cannot impersonate fully populated historical coverage. This counts PROFILES; a season a source cannot cover at all is reported separately below, because the two are different units and are never added.

Seasons outside any committed source window
17
Of seasons, by scope: MLS 17
MLS 17 — these seasons predate the committed source's coverage window entirely, so the archive cannot witness them as empty or full. They are a limit of the source, not a gap in the ingest, and they are deliberately excluded from the profile gap count above.

Source-complete sport scopes
2
Of 5 supported sport scopes
2 sport scopes meet their own source-completeness contract; 3 remain explicitly partial. Each sport has a different source boundary, so this ratio is context—not a universal quality score.

Corpus provenance
Every value below is the committed corpus artifact's own declaration — never inferred, never derived from file timestamps. An absent declaration is shown as absent. Refresh cadence varies with each sport's season, so no judgement is attached to an as-of date.

Last refresh: refreshed (current)
Refresh outcomes are the nightly corpus job's own per-sport ledger from the run completed 2026-09-20. The refresh plan is season-aware, so a sport absent from that run was not attempted — it is reported as such rather than counted as a success.
