HARMONIA

HARMONIA is Babadook's foundational core for composing models, simulations and engineering participants that were not designed as one system. It asks whether their meanings, ports, clocks, mappings, assumptions and guarantees actually fit before it allows them to run together.

Its composition profiles produce constructive plans or explicit counterexamples. Its temporal engine preserves event causality. Its coupled solvers expose residuals, convergence and no-win states. Runtime realizations remain tied to the same validated composition.

The result is not a generic integration bus. It is an evidence-bearing contract for multidisciplinary computation, simulation and foreign-model participation.

HARMONIA does not make incompatible models compatible by renaming ports. It does not convert numerical convergence into physical validity, and it cannot grant trust to a foreign artifact simply because it loads. Participant owners remain responsible for their models and effects.

Profile-Indexed Composition Algebra

Determines whether independently owned models can compose under a declared compatibility profile and produces evidence when they cannot.

Temporal, Event, DEVS and PDES Semantics

Coordinates event-driven and time-stepped participants while preserving their time bases, causality, simultaneity and rollback rules.

Mapping, Conservation and Geometric Transfer

Moves fields, states and quantities between discretizations while testing conservation, frame and support obligations.

Coupled Solvers and Multidisciplinary Analysis

Executes fixed-point, Newton, waveform-relaxation and multidisciplinary analysis loops with convergence, conditioning and participant evidence.

Energy, Passivity and Fidelity Governance

Checks energy exchange, passivity, stability and model-fidelity transitions across coupled participants.

Foreign Model and Process-Simulation Interchange

Inspects and composes FMI/FMU, Modelica-shaped, process-simulation and other foreign artifacts without granting them automatic trust.

Runtime Realization and Consumer Conformance

Compiles coupled plans into CPU, accelerator, distributed and isolated regions while preserving composition and correction evidence.

No-Win Resolution and Counterexample Exchange

Returns explicit incompatibility, ambiguity and unsatisfied-assumption evidence when no lawful composition exists.

Coupled Derivatives and MDA/MDO Export

Propagates derivatives, adjoints and multidisciplinary analysis evidence through coupled participant graphs.

Process and Workflow Simulation Formalisms

Composes discrete-event, queueing, resource, agent and process models while retaining the semantics of work, waiting and ownership.

Correction, Migration and Negotiated Evolution

Propagates participant, mapping, profile and artifact corrections through affected compositions without rewriting historical runs.

Composition Administration and Incident Recovery

Provides policy, quota, support, diagnostics and recovery workflows for large multi-tenant composition estates.
