docs: add comprehensive architectural overview and Phase 5 Session 3 summary
This commit adds two critical research documentation files summarizing the
Tractatus project from inception through current production-ready status.
## Context
- Phase 5 Sessions 1 & 2 indicated "implementation looks promising"
- Session 3 focused on API Memory observations, MongoDB fixes, and inst_016-018
- Need comprehensive system overview for stakeholders and future research
## New Documentation
### 1. Architectural Overview (v1.0.0)
**File**: docs/research/architectural-overview.md
**Purpose**: Definitive reference for system architecture, research phases, and
current status
**Contents**:
- Executive summary (Phase 5 complete, 223/223 tests passing)
- System architecture (4-layer design with hybrid memory)
- Core services documentation (all 6 services detailed)
- Memory architecture (MongoDB + Anthropic API + filesystem)
- MongoDB schema design (AuditLog, GovernanceRule models)
- Phase 5 detailed progress (Sessions 1-3)
- API Memory observations and behavior patterns
- Instruction persistence system (19 active instructions)
- Test coverage (223 tests, 100% passing)
- Production deployment guide
- Security & privacy architecture
- Performance & scalability analysis
- Future research directions (Phase 6 considerations)
- Lessons learned and architectural insights
**Key Sections**:
- API Memory System Observations (Section 3.4)
- Phase 5 Session 3 detailed summary
- inst_016-018 enforcement implementation
- Production readiness assessment
- Complete command reference appendix
**Format**: Markdown with versioning (v1.0.0), anonymized for public release
### 2. Phase 5 Session 3 Summary
**File**: docs/research/phase-5-session3-summary.md
**Purpose**: Session-specific documentation maintaining consistency with
Sessions 1 & 2 format
**Contents**:
- Executive summary (2.5 hours, all objectives exceeded)
- API Memory system observations (first session with new feature)
- 6 MongoDB persistence fixes (detailed with code examples)
- BoundaryEnforcer inst_016-018 enforcement (MAJOR feature)
- Test results (223/223 passing, 61 BoundaryEnforcer)
- Performance metrics (no degradation)
- Key findings and lessons learned
- Production readiness assessment
- Comparison to Sessions 1 & 2
- Complete command reference appendix
**Key Achievement**: Progressed from "implementation looks promising"
(Sessions 1-2) to "production-ready baseline established" (Session 3)
## API Memory Observations
**First session using Anthropic's new API Memory system**
**Key Findings**:
1. Session continuity detection works (detected continuation from 2025-10-07-001)
2. Instructions NOT loaded automatically by API Memory (loaded via session-init.js)
3. API Memory provides conversation continuity, NOT automatic rule loading
4. Architecture clarified: MongoDB (required) + Anthropic API (optional)
5. Graceful degradation when CLAUDE_API_KEY unavailable
6. Performance: No degradation, framework components remained active
**Implication**: API Memory suitable for conversation continuity but does NOT
replace persistent storage. MongoDB remains required for production.
