One project page across the existing W&B source systems. It reads current ledgers and dashboards; it does not create duplicate project truth, approve work, submit externally, move money, or invent missing project facts.
Drive ledgers, source documents, official contracts, approved drawings, A/E/AHJ responses, actual payroll/timekeeping, accounting records, and external submission evidence remain authoritative. A green response here means the source endpoint responded; it does not itself prove contractual, financial, regulatory or project completion.
