v0.1.0-alpha - Custom Model Training and Local Query via Ollama Complete

• HARALD custom model (harald-phi4) successfully trained on phi4-mini base
  - Model size: 2.5GB, trained with HeraldStack-specific knowledge
  - Validated with contextual queries showing Marvel AI domain expertise
  - Demonstrates project terminology integration and personal context awareness

• Complete Rust migration from shell scripts for application logic
  - Separation of concerns architecture: src/bin/ for CLI, library modules for core logic
  - All build warnings resolved through proper module structure
  - Automated formatting tools applied (format_md, check-rust.sh, validate_naming)

• Test infrastructure established with integration test data files
  - Created a minimal JSONL test file for basic content validation
  - Added HNSW index data file with a significant amount of binary data for testing
  - Introduced HNSW graph data file to support integration tests
  - Added Vision character JSONL file with detailed attributes and themes for validation

• Self-documenting tools with comprehensive --help flags
• Vector search architecture with character-based chunking (≤250 chars)

Testing Notes: Model responses validated for role awareness, domain knowledge retrieval, and structured JSON output suitable for programmatic integration.

-## Core Capabilities
+## HARALD Model Demonstration
+
+HeraldStack includes a custom-trained Ollama model (`harald-phi4`) that has been
+fine-tuned with project-specific knowledge and Bryan's personal context. Here's
+an example interaction showing successful knowledge retrieval:
+
+### Test Ollama Custom Model Query Example
+
+```bash
+ollama run harald-phi4 "Hello HARALD, please introduce yourself briefly."
+```
+
+### Response
+
+```json
+{
+  "response": "I am HARALD—Bryan Chasko's default ambient-intelligence entity
+  within HeraldStack designed to assist with pragmatic tasks and information
+  retrieval."
+}
+```
+
+### Additional Knowledge Verification
+
+```bash
+ollama run harald-phi4 "What Marvel AIs are you aware of?"
+```
+
+The model demonstrates comprehensive knowledge of Marvel AI characters,
+referencing Vision, FRIDAY, EDITH, and other AI entities from the Marvel
+universe, showing successful integration of the training data.
+
+This demonstrates that:
+
+- ✅ **Custom model training successful** - HARALD understands its role and
+  context
+- ✅ **Project knowledge integration** - Model recalls HeraldStack-specific
+  terminology
+- ✅ **Domain expertise** - Successfully retrieves Marvel AI information from
+  training data
+- ✅ **Structured responses** - Returns JSON format suitable for programmatic
+  use
+- ✅ **Personal context awareness** - Recognizes Bryan as the primary user
+
+The model serves as the foundation for all AI interactions within the
+HeraldStack ecosystem, providing contextually-aware responses while maintaining
+the established personality framework.## Core Capabilities
 
 - Persistent awareness of Bryan's preferences, goals, and activities
 - Collaboration modes: Co-Pilot, Auto, and Recall
