Records enter as evidence, not conclusions
Public water records become MISI context only after they are tied to a service market, normalized, checked against source provenance, and interpreted through deterministic methodology rules. A raw record is not automatically a conclusion about current system condition.
Normalization preserves provenance
Munimetric distinguishes service markets, water systems, wastewater context, and parent governments. Source records are normalized into those entities while preserving where the record came from, what it measured, and when it was current.
Confidence is part of the output
Confidence reflects factor availability, mapping quality, source freshness, and public eligibility. Low-confidence rows are handled carefully in public ranking pages, and missing data is not fabricated to complete a profile or improve a list.
Where records become user-facing context
Structured records feed state pages, profile pages, Signals, the Screener, and canonical rankings such as High-Stress Water Systems and Utility Data Staleness systems. For framework details, use the MISI methodology and how Munimetric uses public data.
