According to GSA guidelines, contractors must explicitly state how models will be trained, validated, and monitored in production, and how data privacy and chain-of-custody will be preserved for images and metadata. For CBP port operations, include integration pathways with existing X‑ray vendors, physical infrastructure constraints, and radiation-safety coordination. Per FAR 52.204-21 and related clauses, list cybersecurity controls, incident response plans, and subcontractor flowdown assurances. Address data minimization, retention windows, and redaction processes for PII with specific timelines (for example: retain raw images for 30 days, anonymized metrics for 5 years). Provide a phased test plan: lab validation (30–60 days), limited operational pilot (60–90 days), and scaled pilot (6–12 months), with acceptance criteria tied to measurable reduction in manual-review time, target detection sensitivity (e.g., >=95%), and false alarm thresholds.
