Engineering Compiler

167. Full Building Compilation

Full Building Compilation processes the complete declared building configuration across all applicable engineering domains, lifecycle states, dependencies, interfaces, evidence, and requested outputs.

It shall include, as applicable:

architectural and spatial configuration;

structural systems and load paths;

Nodes, Cartridges, members, adapters, and interfaces;

materials and tolerance systems;

utility and environmental systems;

fire and life-safety systems;

sensors, controls, and cyber-physical functions;

manufacturing and construction requirements;

robotic assembly requirements;

Building BIOS configuration;

Digital Twin initialization;

inspection, commissioning, maintenance, and decommissioning requirements.

A Full Building Compilation shall require dependency closure across the entire declared scope. Every active component, interface, parameter, alternative, lifecycle condition, and required evidence item shall be resolved, validated, deferred through an authorized mechanism, or explicitly reported as blocking.

“Full” describes the scope of compilation, not the success of validation. A Full Building Compilation may fail, remain indeterminate, or produce review-only outputs.

The compiler shall distinguish the complete building configuration from external infrastructure, temporary works, site conditions, manufacturer-controlled systems, or future extensions that remain outside the compilation boundary.

A successful Full Building Compilation shall produce a stable Validated Building Configuration identity and the target packages authorized by the completed validation and approval gates.

168. Partial Compilation

Partial Compilation processes an explicitly bounded portion of the building, engineering model, domain, lifecycle stage, or output set.

A partial scope may be defined by:

building zone;

floor or room;

subsystem;

engineering domain;

component class;

Node or Cartridge group;

interface network;

lifecycle operation;

construction phase;

change set;

requested output.

The compiler shall identify all dependencies crossing the partial boundary. External assumptions and unresolved dependencies shall remain explicit and shall be represented as validated inputs, controlled boundary conditions, unresolved requirements, or blocking conditions.

Partial Compilation shall not imply that the selected portion is independent merely because it was compiled separately.

Outputs shall declare:

included and excluded scope;

validated boundary conditions;

external dependencies;

incomplete validations;

affected interfaces;

permitted uses;

prohibited uses;

requirements for integration into the complete building.

A partial result shall not be promoted into a full release package until its boundary assumptions have been reconciled with the complete configuration.

169. Incremental Compilation

Incremental Compilation recompiles only the entities, rules, graphs, calculations, validations, and outputs affected by a change.

The compiler shall use the Dependency Graph, Rule Evaluation Graph, Interface Graph, Evidence Graph, Configuration Graph, and output dependencies to determine the impact boundary.

Incremental Compilation shall:

identify the changed inputs;

determine directly affected entities;

propagate consequences through dependent relationships;

invalidate stale results;

preserve unaffected valid results;

regenerate affected outputs;

record the impact analysis.

Cached results may be reused only when their source revision, Compilation Context, rule set, compiler behavior, dependencies, evidence, and target conditions remain valid.

A minor source edit shall not automatically be treated as a minor engineering change. Changes to interface geometry, material grade, tolerance, load path, firmware, safety logic, certification, or lifecycle state may propagate throughout the building.

Incremental and complete recompilation of the same resolved configuration shall produce semantically equivalent results within declared numerical and platform tolerances.

170. Distributed Compilation

Distributed Compilation allocates compilation tasks across multiple processors, services, organizations, engineering domains, or controlled computing environments.

Distributed execution may be used for:

parallel domain analysis;

large geometric processing;

simulation;

optimization;

manufacturer-controlled component evaluation;

regulatory rule evaluation;

remote evidence verification;

multi-zone or multi-building compilation.

Every distributed task shall receive an identified and immutable subset of the Compilation Context. Its results shall include task identity, input identity, tool version, execution environment, assumptions, provenance, status, and integrity information.

The coordinating compiler shall verify:

dependency consistency;

result authenticity;

version compatibility;

authority boundaries;

deterministic integration;

failure propagation;

completeness of returned results.

Domain services shall not silently modify information owned by another domain. Conflicting distributed results shall be reconciled through explicit precedence, ownership, or multidisciplinary review.

Failure or unavailability of one distributed service shall be reported as unavailable validation or technical failure, not as automatic engineering noncompliance.

It shall support circumstances including:

remote construction sites;

restricted facilities;

emergency operation;

unreliable connectivity;

protected intellectual property;

cybersecurity isolation;

long-term building serviceability.

An offline environment shall use controlled local copies of required schemas, rules, profiles, registries, component definitions, certificates, evidence, credentials, and revocation information.

The compiler shall record the age and synchronization status of every locally cached dependency. It shall detect requirements that cannot be verified offline, including expired credentials, changed regulations, revoked certificates, or unavailable manufacturer data.

Offline Compilation may produce valid outputs where the applicable policies permit it, but it shall not falsely claim that external information was current or verified.

Upon reconnection, locally produced results shall undergo synchronization, conflict detection, revocation checking, and revalidation where required.

Safety-critical building functions shall not be designed to depend exclusively upon continuous cloud compilation availability.

172. Cloud Compilation

Cloud Compilation uses governed remote computing infrastructure to perform compilation, validation, simulation, collaboration, registry access, or output generation.

Cloud services shall provide controls for:

authentication and authorization;

tenant and project isolation;

encryption;

data residency;

intellectual-property protection;

audit logging;

compiler-version control;

dependency locking;

backup and recovery;

service availability;

result integrity.

Uploading a BDL package to a cloud service shall not transfer engineering authority, ownership, or approval responsibility unless separately governed.

Cloud Compilation shall identify the exact service, execution region where required, compiler image, dependency set, execution time, and integrity record.

Service updates shall not silently change reproducible compilation behavior. A new compiler, rule set, generator, or registry state shall produce a distinct Compilation Context.

Cloud-generated outputs shall remain independently verifiable and exportable so that the building does not become permanently dependent upon one provider.

173. Edge Compilation

Edge Compilation performs selected compilation and validation functions near the physical building, manufacturing equipment, construction site, robot, smart module, or Building BIOS environment.

Edge Compilation may support:

verification of delivered components;

comparison of scanned and designed geometry;

assembly-step validation;

robotic task adaptation;

inspection processing;

commissioning checks;

local BIOS update preparation;

emergency-state evaluation;

maintenance and replacement operations.

Edge systems shall operate within explicitly limited authority. They may adapt execution to verified local conditions only within approved tolerance, safety, configuration, and authorization envelopes.

An edge compiler shall not silently redefine the approved engineering design. Deviations beyond its permitted envelope shall stop the affected operation and initiate review or recompilation.

Edge results shall be synchronized with the governed project record when communication becomes available. Conflicts between edge observations, Building BIOS state, Digital Twin state, and central compilation records shall remain visible.

Loss of connectivity shall trigger defined offline and fail-safe behavior appropriate to the consequence of the operation.

174. Cross-Domain Compilation

Cross-Domain Compilation integrates information, requirements, calculations, and constraints from multiple engineering domains into a coordinated configuration.

It shall address interactions among domains such as:

structure and architecture;

geometry and manufacturing;

tolerances and robotic assembly;

materials and fire performance;

utilities and structural interfaces;

sensing and maintainability;

cybersecurity and physical safety;

environmental exposure and durability;

construction sequencing and temporary stability;

lifecycle replacement and load-path continuity.

Each domain shall retain its formal semantics, authority, methods, and professional responsibilities. Integration shall not flatten distinct engineering meanings into generic properties.

Cross-Domain Compilation shall identify shared entities, boundary conditions, ownership rules, conflicts, transferred risks, and multidisciplinary approval requirements.

Where domain models use different coordinate systems, units, identity schemes, detail levels, or configuration assumptions, their transformation shall be explicit and validated.

A coordinated output shall not be issued when independently valid domain results refer to incompatible configurations.

175. Target-Specific Compilation

Target-Specific Compilation transforms the Canonical Engineering Representation into information suitable for a defined Compilation Target.

Targets may include:

analysis;

simulation;

regulatory review;

manufacturing;

procurement;

construction;

robotic assembly;

inspection;

commissioning;

Building BIOS deployment;

Digital Twin initialization;

maintenance;

emergency response;

decommissioning;

reuse and requalification.

Each target shall define:

required input completeness;

applicable validation levels;

required evidence;

permitted unresolved conditions;

output schema;

accuracy and tolerance requirements;

approval gates;

signing requirements;

permitted uses;

prohibited uses.

Target transformation shall preserve traceability to the canonical configuration. Information omitted because it is unnecessary for one target shall not be interpreted as nonexistent in the building model.

Success for one target shall not imply readiness for another. A configuration suitable for simulation may remain unsuitable for manufacturing or construction.

176. Simulation Compilation

Simulation Compilation generates models, scenarios, boundary conditions, parameters, and result mappings for analytical or behavioral simulation.

It may support:

structural behavior;

thermal performance;

airflow;

moisture;

fire and smoke;

acoustics;

energy;

lighting;

utility networks;

construction sequence;

robotic motion;

occupant movement;

emergency scenarios;

degradation and lifecycle performance.

Every simulation package shall identify its purpose, abstraction level, configuration, geometry source, material models, loads, boundary conditions, assumptions, solver, numerical settings, uncertainty, and applicability limits.

Simplifications and model transformations shall remain traceable. Simulation geometry shall not be represented as fabrication geometry unless independently validated for that purpose.

Simulation convergence shall not establish physical correctness. The compiler shall validate input appropriateness, model applicability, result plausibility, sensitivity, and required professional review.

Simulation results may inform engineering decisions but shall not directly authorize physical execution unless incorporated into the governed configuration and required approvals.

177. Manufacturing Compilation

Manufacturing Compilation produces controlled information required to fabricate System05 components and related building elements.

It may generate:
