Software codebases are living artifacts of human intellect designed to express domain logic, structural design, and operational intent. Traditional static analysis frameworks—such as pointer-heavy Code Property Graphs or lowered compiler IRs—strip away this high-level context, introducing massive memory inflation and pointer-chasing latency that isolate static analysis from real-time developer workflows.

Designed, created, and maintained solely by Ahmad Hassan (B-Ted), OpenHeart introduces the Succinct Compositional Program Graph (SCPG)—a formal 7-tuple graph representation:

$$\mathcal{G} = (V, E, \nu, \varepsilon, \tau, \rho, \Sigma_\Phi)$$

By combining Succinct Balanced Parentheses (BP) trees, Compressed Sparse Row (CSR) control flow graphs, Static Single-Assignment (SSA) data flow representations, and Reduced Ordered Binary Decision Diagram (ROBDD) path summaries, OpenHeart achieves up to 128× memory compression while maintaining $O(1)$ bidirectional source-to-diagram traceability.

• 128× Memory Compression: Replaces pointer-heavy AST nodes with Succinct Balanced Parentheses (BP) bitstrings and $O(1)$ Jacobson Rank/Select indexes.
• $O(1)$ Universal Traceability: Monotonic 32-bit token_id anchors link raw source positions directly to IR graph nodes and derived UML elements.
• 19 Universal Diagram Projections: Generates all 14 standard OMG UML 2.5 diagrams + 5 deep compiler pipeline IRs directly from binary graph layers.
• Zero-Backend In-Browser GitHub Ingestion: 100% free-forever client-side cloning and AST parsing running directly on GitHub Pages.
• Declarative Manifest Architecture: Centralized manifest.json controlling categories, diagrams, 16 relationship terminologies, and 24 classifier node schemas with zero hardcoding.
• Zero-Copy Memory Mapping: All 10 compilation pipeline phases serialize into CRC-64 verified binary artifacts mapped directly into OS page memory.
• Multi-Repo Convergence: Validated with $F_1 = 1.0000$ precision across Java, Kotlin, Python, Rust, TypeScript, and C++ codebases.

OpenHeart deterministically derives 19 specialized graph projections organized into 3 distinct categories:

1. 01 · Class Diagram (package_tree engine): Complete class taxonomy, inheritance hierarchies, interfaces, fields, methods, and member visibility.
2. 02 · Package Diagram (hierarchical engine): Multi-tier domain namespaces, package containment hierarchy, and inter-package dependencies.
3. 03 · Component Diagram (hierarchical engine): Modular subsystems, provided/required interfaces, and runtime service wiring.
4. 04 · Composite Structure Diagram (hierarchical engine): Internal parts, ports, and assembly connectors within composite classifiers.
5. 05 · Object Diagram (hierarchical engine): Runtime heap instances, object identities, and reference linkages.
6. 06 · Deployment Diagram (hierarchical engine): Execution environment nodes, devices, and artifact distribution topologies.
7. 07 · Profile Diagram (hierarchical engine): Metamodels, stereotypes, tagged values, and <<extend>> arrows.

8. 08 · Sequence Diagram (sequence engine): Lifeline message traces, synchronous/asynchronous dispatches, and activation bars.
9. 09 · State Machine Diagram (hierarchical engine): Finite states, initial/final pseudostates, transition triggers, and entry/do/exit activities.
10. 10 · Activity Diagram (hierarchical engine): Business logic workflows, control nodes, decision branches, and swimlanes.
11. 11 · Use Case Diagram (usecase engine): Actor boundaries, goal-driven use cases, <<include>>, and <<extend>> dependencies.
12. 12 · Communication Diagram (hierarchical engine): Object collaboration topology with sequenced message ordering numbers.
13. 13 · Interaction Overview Diagram (hierarchical engine): High-level control flow between nested sequence reference frames (ref sd).
14. 14 · Timing Diagram (timing engine): Multi-track temporal waveforms, clock events, and state change transitions over time.

15. 15 · Control Flow Graph (CFG) (hierarchical engine): Basic block partitioning, branching conditions, and loop back-edges.
16. 16 · Data Flow Graph (DFG) (hierarchical engine): SSA def-use value lineage chains and operand dependencies.
17. 17 · Control Dependence Graph (CDG) (hierarchical engine): Reversed post-dominator control conditions governing basic block execution.
18. 18 · Call Graph (CG) (hierarchical engine): Interprocedural call sites, CHA virtual method dispatch resolution, and recursion SCCs.
19. 19 · ROBDD Saturation (hierarchical engine): Canonical Reduced Ordered Binary Decision Diagram path summaries and exact #SAT path counting.
