Pantheon

The semantic substrate for cross-domain composition

The Problem

Domain Fragmentation Prevents Composition

Modern software development is siloed across incompatible representations:

Audio DSL → [export] → CAD Tool → [export] → UI Framework → [export] → ...

Each domain has its own:
- Data formats - Binary blobs, XML, JSON, proprietary formats
- Type systems - Python types ≠ MLIR types ≠ CAD geometry types
- Validation rules - Domain-specific constraints don't transfer
- Compilation targets - C++, LLVM, JavaScript, hardware descriptors

Real-world pain:
- Audio → CAD: Design guitar body acoustics in Morphogen → Can't generate 3D model automatically
- CAD → UI: Parametric design in TiaCAD → Can't generate responsive UI controls for parameters
- AI → Provenance → UI: Track model training pipeline → Can't embed trust metadata in UI components
- Software → Hardware: Design analog effect pedal in code → Can't generate module configuration for physical build

Result: No composition, no reuse, massive integration overhead. Professional workflows require 3-5 tool chains with manual export/import/translate cycles.

The Innovation

ONE universal semantic intermediate representation (IR) for ALL computational domains.

Pantheon enables seamless composition across traditionally siloed domains:
- Audio synthesis (Morphogen)
- Parametric CAD (TiaCAD)
- Process provenance (GenesisGraph)
- UI/Frontend (SUP)
- Analog computing (Philbrick)
- Multi-agent systems (Agent Ether*)

Core Innovations

1. Semantic Types (Not Just Shapes)

# Not just "f32" - semantic meaning with physical units
data_type: Stream<f32, 1D, audio>
sample_rate: {value: 48000, unit: Hz}
frequency: {value: 440, unit: Hz}
temperature: {value: 300, unit: K}

2. Semantic Time (Domain-Specific, Not Universal)
- Audio: samples (48kHz)
- Music: beats/measures (tempo-relative)
- Animation: frames (24fps, 60fps)
- Hardware: cycles (clock-dependent)
- Logical time > wall-clock time - each domain defines its own causal horizon and resolution

3. Universal Node Abstraction

@dataclass
class PantheonNode:
    id: str                          # Unique identifier
    type: NodeType                   # operator, entity, component, module
    domain: str                      # Source domain
    semantics: NodeSemantics         # Intent, category, constraints
    parameters: dict[str, Parameter] # Parameters with units
    metadata: dict[str, Any]         # Domain-specific metadata

4. Validation Framework
- Type checking (semantic types, not just shapes)
- Constraint validation (range, dimensionality, domain rules)
- Dependency resolution (node ordering, data flow)
- Safety checks (prevent invalid cross-domain connections)

5. Provenance-Aware by Design

metadata:
  provenance:
    source_file: guitar_body.kairo
    git_commit: abc123...
    generator_version: morphogen-0.11.0
    parent_documents: [resonance_sim.pantheon.yaml]

Quick Example: Physics-Informed CAD

Scenario: Simulate guitar body resonance → Generate optimal 3D geometry

Step 1: Morphogen simulates acoustics

# resonance_field.pantheon.yaml (output from Morphogen)
version: pantheon-1.0

metadata:
  domain: audio
  creator: morphogen-dsl-v0.11
  timestamp: 2025-11-28T00:00:00Z

nodes:
  - id: guitar_body_resonance
    type: operator
    domain: audio
    semantics:
      intent: "Simulate guitar body resonant modes"
      operator: modal_synthesis
    parameters:
      fundamental: {value: 110, unit: Hz}  # Low E string
      modes: [110, 220, 330, 440]          # Harmonic series
    outputs:
      resonance_field: Field3D<f32 [Pa]>   # Pressure field in 3D space

Step 2: TiaCAD reads Pantheon IR, generates geometry

from tiacad import CADWorkflow
from pantheon import PantheonGraph

# Load Morphogen's resonance simulation
resonance = PantheonGraph.from_yaml("resonance_field.pantheon.yaml")

# TiaCAD adapter reads Pantheon IR
workflow = CADWorkflow.from_pantheon(resonance)

# Use field data to guide body thickness variation
# (thicker where resonance needs damping, thinner where it needs amplification)
body_3d = workflow.generate_geometry(
    thickness_field=resonance.get_output("resonance_field"),
    material="spruce",
    target_mass=1.5  # kg
)

# Export to 3D model
body_3d.save("guitar_body.3mf")

This is impossible in existing tools. You'd need:
- Morphogen or COMSOL (acoustic simulation) → Manual export
- Python scripts to parse simulation data → Brittle translation
- TiaCAD or SolidWorks (CAD modeling) → Manual parameter entry
- Hours of iteration per design change

Pantheon does it automatically. One semantic IR connects both domains.

Status & Adoption

Current Version: v0.1.0-alpha (Design Phase with Proof-of-Concept)

Production Metrics:
- ✅ Morphogen adapter complete - Bidirectional translation working
- ✅ Round-trip fidelity tests passing - Morphogen → Pantheon → Morphogen preserves semantics
- ✅ Semantic time specification integrated across adapters
- ✅ Schema definition complete (nodes, edges, types, validation, metadata)
- 🔄 Python reference implementation in progress (pantheon-core)
- 🔄 Prism adapter (analytics) design complete (Week 7-10 roadmap)

Novel Research Contributions:

  1. Universal Semantic Graph Representation
    - Typed graph nodes with domain semantics (not just structural graphs)
    - Semantic edges carrying types, units, constraints, rates
    - Human-readable YAML/JSON (not binary blobs)
    - Provenance-aware by design (track "how this was created")

  2. Semantic Time Model
    - Time is domain-specific, not universal
    - Audio (samples @ 48kHz) ≠ Music (beats @ tempo) ≠ Animation (frames @ 60fps)
    - Logical time > wall-clock time
    - Each domain defines its own causal horizon and resolution

  3. Cross-Domain Type System
    - Semantic types: meaning + constraints, not just shapes
    - Physical units enforced (Hz, dB, m, kg, K, etc.)
    - Domain-specific constraints (range, dimensionality, rates)
    - Type-safe connections between domains (field → agent force, geometry → audio impulse)

  4. Validation Framework with Domain Constraints
    - Type checking (semantic types)
    - Constraint validation (range checks, unit compatibility)
    - Dependency resolution (node ordering)
    - Safety checks (prevent invalid cross-domain connections)

What This Unlocks:
- Cross-domain workflows - Physics simulation directly drives CAD geometry
- Reusable components - Audio operators compile to both software and hardware
- AI-friendly IR - LLMs can read, write, and reason about Pantheon graphs
- Multi-backend compilation - One design → MLIR, CadQuery, React, firmware

Architectural Principle: One IR to Unify Them All

Pantheon proves that semantic-first design enables composition across traditionally incompatible domains. When domains share a universal IR, professional workflows transform from "export/import hell" to "compose naturally."

The Key Insight:
Most systems treat composition as an afterthought (add glue code later). Pantheon makes composition the foundation:
- Semantic types prevent dimensional errors
- Validation framework catches incompatible connections
- Provenance tracks transformations end-to-end
- Multi-backend compilation enables "one source, many targets"

This solves the fragmentation that forces professional workflows to span 3-5 incompatible tool chains.

Impact: Real-World Workflows Transformed

Before Pantheon:
- Audio design (Morphogen) → Export WAV → Import to CAD (manual parameter entry) → Iterate (hours per cycle)
- CAD model (TiaCAD) → Export STEP → UI builder (manual control creation) → No parameter linking
- AI pipeline (Python) → Manual provenance logging → UI (React) → Separate trust indicators

With Pantheon:
- Morphogen → Pantheon IR → TiaCAD (automatic geometry generation from acoustics)
- TiaCAD → Pantheon IR → SUP (automatic UI controls for parameters)
- GenesisGraph → Pantheon IR → SUP (provenance-aware UI components)
- Morphogen → Pantheon IR → Philbrick (software simulation → hardware build)

Use Cases Enabled:

  1. Physics-Informed Design
    - Acoustic simulation drives CAD geometry (guitar bodies, speaker enclosures)
    - Thermal analysis optimizes heat sink topology
    - Fluid dynamics guides aerodynamic shape

  2. AI-Driven CAD
    - Generative design with provenance tracking
    - Parametric models with AI-suggested optimizations
    - Explainable geometry (show why each parameter exists)

  3. Hardware/Software Co-Design
    - Design analog circuit in software → Generate hardware module config
    - Validate software simulation against physical prototype
    - Bridge digital/analog computing (Morphogen ↔ Philbrick)

  4. Provenance-Aware Applications
    - UI components display trust metadata automatically
    - Audit trails embedded in outputs
    - Reproducible workflows (capture entire pipeline in Pantheon IR)

Adoption Path (v1.0 Goals):
- 5+ domain adapters production-ready (Morphogen ✅, TiaCAD, GenesisGraph, SUP, Philbrick)
- 10+ cross-domain example workflows
- Industry adoption in audio production, CAD/CAM, AI/ML tooling
