Scenario Principles & Assumptions:
- Margin recovery assumes leakages occur in unverified BOQ surface area calculations and material scrap rate drift.
- Admin hours saved assume automated synthesis of daily morning briefs and variation order workflows.
- All monetary values are expressed in Vietnamese Dong (VND).
📌 Sensitivity Note: Results change materially with margin leakage, data quality, project mix, contract structure, and implementation adoption.

Morning Brief Disclaimer: The Morning Brief uses deterministic calculations from the active dataset. It does not validate business accuracy, completeness, authority, or forecast reliability.
Simulator Disclaimer: The simulator uses scenario assumptions. It does not validate financial accuracy or predict actual outcomes.
Schema Validation Disclaimer: Schema validation checks data shape and arithmetic consistency only. It does not verify source authority, contractual correctness, accounting accuracy, completeness, or suitability for operational decisions.
