## 2. Dual-Market GEO Regulatory, Statutory & Financial Standards (US USD $ + India INR ₹)
- **United States (USD $) Regulatory & Accounting Baseline**: AIA Document G702/G703 Pay Applications, CSI MasterFormat WBS coding, Federal Acquisition Regulation (FAR) / Davis-Bacon certified payroll, OSHA 29 CFR Part 1926 site safety, statutory lien waivers, and US GAAP ASC 606 percentage-of-completion in USD ($).

- **Commercial & Reconciliation Benchmark (USD $ / INR ₹)**: Prevents 2.0%–5.5% project cost overrun ($150,000–$1.2M USD | ₹1.2 Cr–₹10 Cr INR per major EPC contract) from over-certified subcontractor quantities, unrecovered free-issue steel/cement wastage, and unbilled variation orders.

## 3. Deterministic Control-Gate Architecture & System Boundaries
- Hard BOQ ceiling gates blocking subcontractor RA bill lines from exceeding approved work-order quantities or drawing revisions without a formal Change Order.
- Theoretical-vs-actual free-issue material reconciliation (steel, cement, cable, piping) required before final subcontractor retention release.
- Joint digital Measurement Book (e-MB) sign-off binding site execution engineers, QA/QC inspectors, and commercial QS teams.
