**Core Modules** + +**`lib.rs`** - Library coordination and re-exports +- Provides unified API for the entire molecular library +- Re-exports key types from all modules +- Minimal dependency coordination + +**`main.rs`** - Application entry point (mlclr binary) +- Command-line interface for the molecular MCP server +- Server startup, configuration loading, signal handling +- Multi-transport coordination (TCP, stdio, FIFO) + +### 📥 **Ingestion Module** (`ingestion/`) + +**Purpose**: Handle various input mechanisms for molecular events + +- `fifo_ingestion.rs` - FIFO-based real-time event streaming +- Future: HTTP endpoints, file watchers, webhooks + +**Why isolated**: Input mechanisms are independent and may grow significantly as we add more protocols. + +### 🏗️ **Models Module** (`models/`) + +**Purpose**: Define all data structures, configurations, and schemas + +- `config.rs` - System configuration and settings +- `embeddings.rs` - ML embedding models and utilities +- `schema/` - Vector-native event schema (decomposed for LLM-friendliness) + +**Schema Decomposition Rationale**: +- **`events.rs`** - Core event types (200 lines): Event definitions were complex enough to warrant focused attention +- **`content.rs`** - Content structures (175 lines): Event payloads have rich structure deserving separate module +- **`queries.rs`** - Search utilities (200 lines): Query handling and timestamp utilities are distinct concerns + +### ⚙️ **Processing Module** (`processing/`) + +**Purpose**: Event processing, analysis, and transformation pipeline + +- `ring_buffer.rs` - Multi-tier buffering with flood protection 🔄 *[NEEDS SPLIT]* +- `semantic_classifier.rs` - AI-powered event categorization +- `compression_pipeline.rs` - Event compression and archival 🔄 *[NEEDS SPLIT]* + +**Future decomposition needed**: Ring buffer and compression pipeline exceed 400-line guideline. + +### 🌐 **Server Module** (`server/`) + +**Purpose**: MCP server implementations and communication protocols + +- `core.rs` - Central VectorMolecularSystem orchestration +- `tcp.rs` / `stdio.rs` - Transport-specific implementations +- `tools.rs` - MCP tool method implementations +- `fifo_consumers.rs` - Background FIFO processing +- `json_rpc.rs` - JSON-RPC protocol handling 🔄 *[NEEDS SPLIT]* + +### 💾 **Storage Module** (`storage/`) + +**Purpose**: Data

decomposed +- All files in `models/schema/` - Successfully decomposed +- Most server, ingestion, and utility files + +### 🔄 **Still Need Decomposition** +1. **`processing/ring_buffer.rs`** (592 lines)

**`models/config.rs`** (421 lines) - Configuration structures + +### 🎯 **Target Architecture Benefits** + +**Maintainability**: Each file has a single, focused responsibility +**Testability**: Components can be unit tested in isolation +**Extensibility**: Easy to add new storage backends, server types, etc. +**LLM-Friendly**: Perfect file sizes for AI-assisted development +**Type Safety**: Clear module boundaries with well-defined interfaces + +## 🚀 **Next Steps** + +1. **Complete remaining decompositions** for files exceeding 400 lines +2. **Add trait abstractions** for Storage and Processing layers +3. **Implement domain-specific error types** (replace anyhow) +4. **Add comprehensive integration tests** for decomposed modules +5. **Performance benchmarking** to ensure decomposition doesn't impact speed + +## 🔧 **Development Workflow** + +**For AI Assistants**: Each module is now appropriately sized for focused development +**For Humans**: Clear separation of concerns makes debugging and feature development easier +**For Testing**: Isolated modules enable comprehensive unit testing strategies + +--- + +*This architecture achieves the goal of
