Risks & flags

• Extremely long open window (over 3 years) suggests a standing/rolling parent announcement rather than a competitive single-award solicitation — not wired for a specific bidder but atypical for standard procurement
• Minimal scope detail provided; full program requirements would be found in the complete Funding Opportunity Announcement (FOA) PA-26-002
