docs: Claude → Codex MVP Phase 1 Implementation Handoff

## Purpose
Comprehensive handoff document from Claude (Architecture) to Codex
(Implementation) for MVP Phase 1 (Weeks 1-10).

## Contents

### What Was ACCEPTED (4 MVP-Critical Additions)

1. **Sovereignty Firewall** (Week 1-2) - PRIORITY 1
   - AST validation of ingestion feeders
   - Runtime hot path assertions
   - CI/CD integration
   - Complete code examples with tests

2. **Compressed Audit Journal** (Week 3-4) - PRIORITY 2
   - Ternary compression (10-20x reduction)
   - B-tree indexing for O(log n) queries
   - Binary serialization with SHA256 hashing
   - Complete implementation with benchmarks

3. **Self-Healing Wrappers** (Week 5-6) - PRIORITY 3
   - Retry with exponential backoff
   - Circuit breaker pattern
   - Graceful degradation with fallback
   - Integration points for all critical operations

4. **Basic Temporal Metadata** (Week 7-8) - PRIORITY 4
   - Lamport clock for causality
   - Vector clock for distributed sync
   - Event ID with parent chain
   - Manifest version binding

### What Was DEFERRED (7 Research Track Items)

Clearly explains why these fascinating partner ideas are deferred:
- Consciousness Analysis (Grok)
- Quantum Cognition (Qwen)
- Morphic Resonance (Kimi)
- Oneiric Engine (DeepSeek)
- Volition Cortex (GLM 4.7)
- Scaling Laws (Multiple)
- Multi-Agent Consensus (GLM 4.7)

Each includes:
- Why deferred (no computational definition / beyond MVP scope)
- What's valuable (reframe as implementable concept)
- Future research path (when/how to explore)

### Implementation Details

**Complete Code Examples:**
- ~800 lines of production-ready Python code
- Full class implementations with docstrings
- Integration examples showing where to add
- Test specifications with assertions

**Weekly Milestones:**
- Week 1-2: Sovereignty Firewall
- Week 3-4: Compressed Audit Journal
- Week 5-6: Self-Healing Wrappers
- Week 7-8: Basic Temporal Metadata
- Week 9-10: Integration & Testing

**Success Criteria:**
Clear definition of done for MVP Phase 1 completion.

**Key Files to Reference:**
- KNOWLEDGEVERSE_SPECIFICATION.md (v5.0 complete spec)
- KNOWLEDGEVERSE_MVP_ROADMAP.md (implementation bible)
- Partner synthesis (context)

### Tone & Clarity

Written in clear, actionable language:
- No ambiguity
- Explicit priorities
- Complete examples
- Test requirements
- Blocker escalation path

## Impact

This document provides Codex with:
✅ Unambiguous implementation path
✅ Complete specifications for 4 MVP features
✅ Full code examples (copy-paste ready)
✅ Clear test requirements
✅ 10-week timeline with milestones
✅ Explicit acknowledgment of deferred research

## Next Step

Codex can now begin Week 1-2 implementation of Sovereignty Firewall
with complete specification and test requirements.
