Agent vs. rule baseline
2/5 address(es) the agent overrode the rule baseline. The baseline is the same policy used for offline triage; the deviations below are the agent's value-add.
| Address | Baseline action | Agent action | Baseline confidence | Agent confidence | Verdict |
|---|---|---|---|---|---|
| Address 2 | testkit_dispatch | priority_outreach | high | high | overrode Agent reasoned: "Score 79 (priority band, highest). Rooftop parcel match, no missing inputs — high confidence. Tract 97% pre-1980 (49/50). Severe contamination concentration: Superfund 380m, brownfield 260m, RCRA TSD 480m, UST facility 95m, 4 open LUSTs within 1km — contamination maxed at 30/30. Water service present. This is the highest-risk address with extreme source density plus pre-war housing. Door-knock + letter (priority_outreach) is warranted as these co-occurring high-contamination and pre-war signals sit at the top of the priority band." |
| Address 4 | testkit_dispatch | priority_outreach | high | high | overrode Agent reasoned: "Score 72 (priority band). Rooftop parcel match (parcel_grade=true), no missing inputs — high confidence in parcel-level data. Tract 94% pre-1980 (47/50). Contamination elevated: brownfield 420m, UST facility 180m, 3 open LUSTs within 1km, near a Superfund within 8km. Water service present (no lead-in-water gap). Combination of high pre-war housing and multiple active contamination sources within close range argues for priority_outreach door-knock + letter rather than self-serve kit." |

Severe contamination concentration: Superfund 380m, brownfield 260m, RCRA TSD 480m, UST facility 95m, 4 open LUSTs within 1km — contamination maxed at 30/30. Water service present.

Contamination elevated: brownfield 420m, UST facility 180m, 3 open LUSTs within 1km, near a Superfund within 8km. Water service present (no lead-in-water gap).

| water_service_gap | 0/20 | inside a mapped community water system service area (regulated under Lead & Copper Rule) |
Agent reasoning:
Score 61 (priority band, low edge). Rooftop parcel match, no missing inputs — high confidence. Tract 89% pre-1980 (45/50). Contamination moderate: brownfield 950m, UST facility 610m, 1 open LUST within 1km, no close Superfund proximity. Water service present (no gap). The pre-war housing is the main driver; contamination is more moderate than top-tier cases. Given moderate contamination, provided water service, and self-serve capability, I dispatch a test kit rather than door-knock outreach.

| pre_1980_housing_share | 35/50 | 70.4% of tract housing built before 1980 (lead-paint era) |
| legacy_contamination | 1/30 | nearest active underground-storage-tank facility 5400 m away |
| water_service_gap | 20/20 | outside any mapped EPA Community Water System service area — likely private well, no federal lead-in-water oversight; domestic-well household density class "High" |
Agent reasoning:
Score 56 (moderate band). parcel_grade=false means street-centerline estimate, so parcel-specific distances are not rooftop-reliable — cap confidence at medium. ~30% of contamination inputs null (Superfund/brownfield/RCRA), further supporting medium confidence. Critical red flag: OUTSIDE any community water service area with high (41.2/km2) domestic-well density — no federal lead-in-water oversight, a strong well-water exposure risk. This red flag in the moderate band justifies a test kit dispatch despite the lower overall score.

| water_service_gap | 0/20 | inside a mapped community water system service area (regulated under Lead & Copper Rule) |
Agent reasoning:
Score 9 (low band). Rooftop parcel match, but Superfund and RCRA fields null (2 of ~6 inputs missing, ~1/3), so confidence is medium. Tract only 10% pre-1980 (5/50); nearest brownfield 6800m; within regulated water service area. No contamination, no pre-war housing, no water-service gap. Clear low-risk profile — no testing action needed.
