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."

1. Address 2 — 79/100 [PRIORITY]

Component Points Basis
pre_1980_housing_share 49/50 97.0% of tract housing built before 1980 (lead-paint era)

Agent reasoning:

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.

3. Address 5 — 61/100 [PRIORITY]

Component Points Basis
pre_1980_housing_share 45/50 89.0% of tract housing built before 1980 (lead-paint era)
legacy_contamination 16/30 nearest Superfund (EPA SEMS) site 7200 m away; 1 site(s) within 8 km; nearest brownfield (EPA ACRES) 950 m away; 4 site(s) within 8 km; nearest RCRA TSD facility 3900 m away; 1 facility(ies) within 8 km; nearest active underground-storage-tank facility 610 m away; 1 open leaking-underground-storage-tank release site(s) within 1 km
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.

4. Address 1 — 56/100 [MODERATE]

Component Points Basis
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.

5. Address 3 — 9/100 [LOW]

Component Points Basis
pre_1980_housing_share 5/50 10.0% of tract housing built before 1980 (lead-paint era)
legacy_contamination 4/30 nearest brownfield (EPA ACRES) 6800 m away; 1 site(s) within 8 km; nearest active underground-storage-tank facility 2300 m away
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.
