## 🔗 Repository Relationship: Knowledge3D ↔ PM-KR

**Two-Track Approach:**

| Repository | Purpose | Status | Link |
|------------|---------|--------|------|
| **Knowledge3D** | Reference implementation, production system, living 
documentation | Active development | 
[GitHub](https://github.com/danielcamposramos/Knowledge3D) |
| **pm-kr** | Open standards, collaborative specifications, test suites 
| Standards track | [W3C CG](https://www.w3.org/community/pm-kr/) |

**Think of it like:**
- **WebKit/Chromium** → Standards-compliant browser implementations
- **W3C HTML/CSS specs** → Open standards everyone can implement
- **Knowledge3D = Browser**, **PM-KR = Spec**

**Important**: Knowledge3D motivates the group's discussions but does 
NOT constrain them. **We welcome alternative implementations and 
approaches!**

## 🎯 Year 1 Tracks (Shaped by Early Discussions)

Even before the official launch, deep technical discussions with 
founding members have shaped PM-KR's first-year priorities:

### Track 1: OpenFn Integration Architecture
**Lead**: OpenFn Organization (production validation, 40+ countries)
- Real-world BPM workflow integration
- Governments/NGOs/healthcare use cases

### Track 2: BPMN → PM-KR Compilation Strategy
**Lead**: Adam Sobieski (workflow verification, audit schema)
- BPMN graphical workflows compiled to procedural programs
- Verification via Lean4 (Track 4)

### Track 3: State/Context Ontology
**Lead**: Adam Sobieski (audit message schema)
- "At point X during procedure Y, observed Z"
- OpenTelemetry mapping (traces, spans, context propagation)

### Track 4: Lean4 Formalization
**Lead**: TBD (theorem proving for correctness)
- Formal verification of PM-KR semantics
- Collaboration with proof assistant community

### Track 5: Ethics & Safety for AI Agents/Robots
**Lead**: Adam Sobieski (Schema.org policy work, GitHub #4569)
- Multi-agent coordination via Galaxy Universe
- Safety predicates in procedural forms (MUST/MUST NOT)
- Structured validation reports for audit compliance

### Track 6: Developer Adoption & Cognitive Load Minimization
**Lead**: Jonathan DeRouchie (familiar technical concepts)
- Multiple Mental Models Guide (file system, OOP, graph DB, 3D modeling)
- Gremlin → K3D Migration Guide (with Marko Rodriguez)
- Getting Started for Different Roles (designers, devs, PMs)

## 💡 Early Collaborative Insights (Pre-Launch)

### Jonathan DeRouchie: Form→Meaning & Cognitive Load

**Key Insight**: "Users are more likely to adopt a framework that uses 
or simplifies existing language, concept or structure."

**Contributions:**
- Recognized **Form→Meaning Framework** mirrors 40,000 years of human 
evolution (cave paintings → letters → words → grammar → philosophy)
- Proposed **Multiple Mental Models** approach:
   - File System: House = directories, Rooms = folders, Objects = files
   - OOP: Classes, inheritance, procedural composition
   - Graph Database: Gremlin-style traversal (with Marko Rodriguez)
   - 3D Modeling: Blender/Maya/Unity (scenes, objects, materials)

**Impact**: Led to **Track 6 proposal** for developer adoption.

### Adam Sobieski: Hippocampus, Execution State, Ethics

**Key Insight**: "Based on your interest in spatial approaches, I assume 
you've also studied the hippocampus?"

**Biological Grounding:**
- Validated K3D's **hippocampus-inspired architecture** (spatial 
navigation, episodic memory, memory consolidation)
- Computational analogue: K3D House Universe = hippocampus functions

**Technical Contributions:**
- **Execution State Embeddings**: 768-dim vectors encoding procedural 
state + semantic context (K3D already implements this!)
- **Incremental Validation**: "At point X during Y, is candidate action 
A_i correct, efficient, safe, ethical?"
- **Faith Engine**: K3D's 0.70 confidence threshold for safety validation
- **Audit Message Schema**: "at point X during Y, observed Z" (credited 
to Adam in PM-KR spec)

**Impact**: Led to **Track 5 proposal** for ethics & safety.

**Multimodal Narrative Vision:**
- Natural language narration (Galaxy introspection mode)
- Procedural video generation (K3D-VID, 200:1 compression)
- 3D visualization (humans walk through robot's "memory palace")
- Structured audit trail (machine-verifiable + human-readable)

### Marko Rodriguez: Graph Traversal Expertise

**Role**: Apache TinkerPop founder, Gremlin creator, Knowledge3D 
repository collaborator

**Contribution:**
- **Gremlin → K3D Mapping**: K3D Galaxy navigation = 3D graph traversal 
(extends Gremlin to spatial reasoning)
- **Industry Validation**: Gremlin powers DataStax, Neo4j, major graph 
databases worldwide
- Ensures K3D builds on established graph theory

**Connection:**
```
Gremlin (2D graph traversal)  →  K3D Galaxy (3D graph traversal)
Graph nodes                   →  K3D Nodes (stars in 3D space)
Graph edges                   →  Semantic proximity (spatial distance)
g.V().has('name','X')        →  galaxy.query(embedding, top_k=10)
```
