Section 11 of 104
9. BDL–Compiler–BIOS–Digital Twin Integration
Stable section ID: S05-CON-016-SECTION-11 · 17 content blocks
The BDL–Compiler–BIOS–Digital Twin chain shall provide the core digital integration architecture of System05.
The Building Definition Language shall express the intended Building configuration, requirements, Components, Interfaces, relationships, Profiles, constraints, and lifecycle expectations.
The Engineering Compiler shall interpret and validate the BDL, resolve applicable rules and compatible entities, identify errors or unresolved conditions, and generate controlled implementation outputs.
The Building BIOS shall become the authoritative configuration and state foundation for the actual Building after approved compilation, installation, verification, and commissioning.
The Digital Twin shall be generated from and synchronized with the authoritative BIOS and associated operational Evidence. It shall represent the Building’s current or explicitly time-stamped physical state rather than an independent fictional model.
The integration chain shall preserve:
source identity and Version;
applicable Profiles and requirements;
compilation results and warnings;
approved configuration;
installed Product identities;
Interface and compatibility states;
verification and commissioning Evidence;
operational changes and lifecycle events.
Compilation shall not automatically constitute engineering approval. Human or institutional authorization shall remain required wherever assigned by law, professional practice, or System05 governance.
A change to the operational Building shall not be considered complete until the physical action, required inspection, BIOS update, and Digital Twin synchronization have been reconciled.
Where the Digital Twin conflicts with verified physical Evidence, the discrepancy shall be reported and controlled. The Digital Twin shall not silently overwrite the Building BIOS.
