IRCP-DLM Integration Plan

# IRCP-DLM Integration Plan
## Comprehensive Tracking Document

Started: 2025-12-07
Status: 🔵 In Progress
Current Phase: Week 3 - Training Pipeline Integration

---

Overview

This plan tracks the iterative integration of IRCP, TPO, and DLM packages into a unified, production-grade system. Each task is checkable, and progress is tracked across multiple detailed markdown files.

Key Principle: DLM's coordinate system is the foundation - we enhance and unify, not replace.

Critical Decisions Log

### Decision 1: Coordinate System Foundation ✅
Date: 2025-12-07
Decision: Use DLM's `ChainCoordinate` as the foundation, enhance with TPO's calculation methods
Rationale: DLM coordinates have been the basis from the beginning, code already exists
Impact: Medium - Requires careful merging but preserves existing logic

### Decision 2: Backward Compatibility ✅
Date: 2025-12-07
Decision: Maintain 100
Rationale: Avoid breaking existing integrations
Impact: High - Requires compatibility shims and gradual deprecation

### Decision 3: IRCP Model Integration ✅
Date: 2025-12-07
Decision: Extend dlm/response/embedding_provider.py for IRCP model
Rationale: Recently created BaseEmbeddingProvider provides perfect foundation
Impact: Low - Clean integration point already exists

How to Use This Plan

1. Start a Phase

# Open the phase file
open PHASE_2_1_COORDINATES.md

# Read objectives and tasks
# Check off tasks as you complete them
# Update status in this master file

### 2. Track Progress
- Each phase file has detailed tasks with checkboxes
- Update this master file after completing each phase
- Document any blockers or decisions in phase files
- Resume from where you left off using phase files

### 3. Iterate
- Complete phases sequentially within each week
- Can work on multiple weeks in parallel if no dependencies
- Update status indicators: ⏳ Pending → 🔵 In Progress → ✅ Complete

### 4. Review & Adjust
- Weekly review of progress
- Adjust timeline if needed
- Document lessons learned
