PHMSA 49 CFR 192 / 195 obligations baked in. Every Class A triggers a 72-hour notification workflow. Every dig program ties evidence back to the NOPV audit trail. This integrates directly with AG.13 Regulatory Intelligence.

Model-assisted classification. Every anomaly is auto-classified per PHMSA criteria and sense-checked by the integrity engineer. The model routes critical findings ahead of the 90-day review cycle.

What goes in · what comes out
The composite score blends six signals that a senior integrity engineer weighs manually today. We don't replace the engineer — we give them a prioritized list on a Monday morning instead of 847 rows in a spreadsheet.
Every score links back to source ILI data, SCADA pressure history, and the obligations matrix. Engineers can override; overrides are logged as training data.
Output: (1) daily risk score per segment, (2) Class A/B/C auto-classification per anomaly, (3) prioritized dig list with PHMSA-deadline-aware sequencing.
