Loading pattern matches
The dataset shows contracting-office × product-or-service cells where a single vendor or small group receives a large share of obligations over the last three years. Concentration can be structural (a sole authorized source, an academic affiliate, a regional market) and is a prompt to review competition, not evidence of its absence.
Glassbox VA surfaces correlations and observations, not findings of misconduct. Severity is the size of the match (dollars, growth ratio, concentration or firm count), not the likelihood of a problem; evidence strength (0–1) shows how well the data supports the match. Both are a starting point for review, not a verdict.
The match meets the pattern threshold, in the lower size band.
A mid-sized match. Pull the source records and read the listed benign explanations first.
The largest size band for this pattern. Larger matches are listed first; size is not evidence of a problem.
Severity is computed from the detection signal · per (awarding office, PSC) over the rolling 36 months to the corpus as-of date · cell obligations ≥ $10M · ≥ 3 recipients · HHI = Σ recipient share² × 100² ≥ p90 of cell HHIs within the administration AND ≥ 1500 floor · bands ≥5000 extreme, ≥2500 highly, ≥1500 moderately concentrated · signal = HHI
The dataset shows 252-NETWORK CONTRACT OFFICE 12 (36C252) obligating $36.7M for PSC Q301 (REFERENCE LABORATORY TESTING) to 12 recipients over the 36 months to 2026-09-04. HHI 6653 (extremely concentrated; VHA 90th percentile 6156); the top recipients (QUEST DIAGNOSTICS INCORPORATED, LOYOLA UNIVERSITY HEALTH SYSTEM, BLOODWORKS) account for 92% of the cell.
Once a match is identified, the dataset suggests these review actions. Glassbox VA does not prescribe outcomes — these are calibrated options for contracting officers, auditors, and program officers, framed as correlations to investigate.
AbilityOne, utilities, a single local provider or a proprietary product make concentration expected. The PSC and office tell you which case applies.
Awards with one offer on competed actions, repeated over years, suggest the market was not reached. Recent sources-sought notices help test that.
Re-score each refresh to see whether concentration is stable, growing or easing.
These are calibrated suggestions, not directives. The dataset shows the pattern; the responsible officials decide the response.
Aggregated from the matches below. Severity bands are calibrated per pattern; counts and dollar totals reflect this snapshot only.

Why this may be benign · Small contracting offices (a single medical center or VISN network contracting office) buy from a narrow local market; high concentration can reflect geography rather than steering.
