research: add memory tool integration breakthrough (v1.1)
**Phase 5 Priority Finding**: Anthropic Claude 4.5 memory/context APIs
provide game-changing pathway for persistent LLM governance.
## Changes
**Section 3.6: Memory Tool Integration (Approach F)**
- Leverages Claude 4.5 memory tool for persistent rule storage
- Context editing API for automated context management
- Middleware proxy pattern for enforcement
- PoC timeline: 2-3 weeks (vs 12-18 months for full research)
- Feasibility: HIGH (API-driven, no model changes needed)
**Section 15: Recent Developments (October 2025)**
- Documents breakthrough discovery on 2025-10-10
- Strategic repositioning: immediate PoC vs long-term study
- Updated feasibility assessment with memory tool approach
- Two-track plan: Track A (PoC, active), Track B (full study, on hold)
## Impact
- Practical feasibility dramatically improved
- No fine-tuning or model access required
- Solves persistent state + context overflow challenges
- Enables multi-session governance, audit trails
- De-risks long-term research investment
## Metadata
- Document version: 1.0 → 1.1
- Word count: ~5,000 → 6,084 words
- New sections: 2 major additions (~1,000 words)
- Status: Phase 5 priority, PoC in progress
