Method and Validation Center

Release integrity, separate from outcome validation.

California UCRI is generated through deterministic source, join, formula, ranking, and output checks. Those controls support reproducibility. They do not establish field validity, causal impact, eligibility, or project outcomes.

Source reconciliation

Missing records remain visible

The official CES 5.0 table contains 9,106 unique tract records. California geometry contains 9,129 records. Twenty-three special or offshore-style tract GEOIDs have no CES 5.0 row. Canopulse leaves those EBS values missing and applies the documented provisional or unscored rules.

Control register

Exact checks and current status

Completed means the deterministic release assertion passed. It does not mean an external reviewer validated outcomes.

Official source checksum

Complete

The CalEnviroScreen 5.0 CSV is pinned to SHA-256 3abb90971997cc151afe8c0ba46a01f544d1f8aaf4bc8b5d1f72c6d46007a296.

Source-row uniqueness

Complete

9,106 official tract rows were parsed with unique tract identifiers and non-missing PollutionP values.

Tract reconciliation

Complete

9,106 California tract GEOIDs matched. The 23 records absent from CES 5.0 remain missing; no values were invented.

Formula reproduction

Complete

The fixed 25%, 25%, 15%, 20%, and 15% component weights reproduce released scores within rounding tolerance.

Score-kind accounting

Complete

9,033 fully scored, 74 provisional, and 22 unscored records reconcile to 9,129.

Ranks and priority bands

Complete

State and county ranks are assigned only to fully scored records. Provisional and unscored records remain outside released ranks.

Geometry and tiles

Complete

Official 2020 tract geometry is delivered through scale-dependent PMTiles and does not depend on score recomputation.

Independent methodology review

In progress

External review status is reported separately from deterministic release integrity.

Outcome and field validation

Not complete

Canopulse does not represent screening scores as validated project outcomes, causal effects, or field conditions.

What these checks do not prove

They do not prove medical risk, causation, regulatory status, funding eligibility, official designation, parcel suitability, intervention effectiveness, or real-time conditions. UCRI remains a tract-level screening tool that requires current local evidence and professional review before project decisions.
