Linkage Quality Audit

2026-03-14 • By Codex

This report audits player identity continuity structurally: source-ID semantics, transition-link methods, adjacent-lane coverage, safe remaining NCAA gaps, and suspicious shared hubs that may need cleanup.

  • Generated: 2026-03-14T22:13:04-07:00
  • Goal: improve linkage with measured rules, not ad hoc player patches.

Key Reads

  • scoped_id_unique is still the largest split-hub recovery method with 1813 links.
  • The new NCAA->Euro abbreviation bridge (initial_last_euro_unique) contributes 575 links.
  • Conservative remaining NCAA internal misses are down to 4 total pairs across the audited ladders.
  • Generic NCAA skip-level continuity now contributes 27 men's D3->D1 links and 13 women's D3->D1 links.
  • Source-native bridge footprint now includes 4046 college_reference linkage rows, 560 pro_reference linkage rows, and 3 explicit BR->SR transition links.
  • Remaining safe mainline cached-name mismatches are now scoped=0 and unscoped_unique=0.
  • Suspicious shared-hub cleanup queue currently surfaces 25 cross-source/cross-league hubs.

Source Identity Rules

Source Lookup Scope Cross-League Stable ID Notes
pro_reference global no Stable pro-reference player slugs within pro coverage.
mainline source_league no League-scoped numeric ids; not globally unique across leagues.
eurocup global no Stable within source; separate source from euroleague.
euroleague global no Stable within source; separate source from eurocup.
ncaa global no Single-source ids do not span leagues; players can acquire multiple ids over time.
college_reference global no Stable player-page slugs within college-reference college coverage.
pro_box global yes Stable person ids across NBA/G League coverage.

Adjacent Pair Continuity

Shared hub = already canonicalized same player. Transition link = split-hub continuity edge.

Safe NCAA Remaining Gaps

Suspicious Shared Hubs

These hubs carry multiple strong surname clusters across sources. They are not proven bad merges, but they are the highest-value cleanup candidates.
