Sample transparency record
A read-only artifact for demonstration move RC-2041. Every figure is computed by the deterministic engine, never typed by hand.
Every figure below carries its provenance stamp. Computed by engine 2.7.1 against dataset v4.2.
- Dataset v4.206·14·2026
Added Q2 2026 closings and expanded ZIP-level cohorts in 14 metros. Referral-fee medians firmed slightly as more partner data cleared validation.
- Engine 2.7.005·02·2026
Percentile interpolation moved to a Harrell-Davis estimator for small cohorts, smoothing p25/p75 near the k-anonymity floor. Minimum cohort size held at k=5.
- Dataset v4.104·28·2026
First inclusion of guaranteed-buyout carrying-cost data from three national RMC partners, enabling GBO-specific benchmarks.
- Dataset v4.003·15·2026
First production benchmark. Six fee kinds across national and metro cohorts, k-anonymity floor set at k=5, nightly aggregation established.
