Building BIOS Architecture

The Configuration Engine maintains, validates, compares, and changes the authoritative building configuration.

It shall manage four distinct configuration views:

Declared Configuration: information supplied by manufacturers, designers, or registered components;

Approved Configuration: configuration formally authorized for the building;

Observed Configuration: configuration detected or verified in the physical building;

A configuration object shall identify:

object identity;

object type and version;

location;

interfaces;

relationships;

capabilities;

dependencies;

selected Profiles;

permissions;

approved limits;

evidence;

effective date;

authorizing authority.

A configuration change shall follow:

submission;

identity and authority check;

schema validation;

compatibility validation;

dependency analysis;

policy evaluation;

safety and Engineering Profile validation;

impact assessment;

approval;

transactional application;

physical verification where required;

baseline update;

The Configuration Engine shall support rollback only when the previous physical and digital conditions remain achievable and safe. A digital rollback shall not falsely represent reversal of an irreversible physical change.
