Diverga Memory System v7.0

Overview

Human-centered research context persistence with:

• 3-Layer Context System
• Checkpoint Auto-Trigger
• Cross-Session Continuity
• Decision Audit Trail
• Research Documentation Automation

Quick Reference

Context Loading Keywords

English: "my research", "research status", "where was I", "continue research", "what stage"

Korean: "내 연구", "연구 진행", "연구 상태", "어디까지", "지금 단계"

Commands

Command	Description
/diverga:memory status	Show project status
/diverga:memory context	Display full context
/diverga:memory init	Initialize project
/diverga:memory decision list	List decisions
/diverga:memory archive [STAGE]	Archive stage
/diverga:memory migrate	Run migration

Priority Context (v8.2 — Compression Resilience)

MCP Tools for Priority Context

Command	MCP Tool	Description
Read priority	diverga_priority_read()	Read 500-char context summary
Write priority	diverga_priority_write(context)	Update context summary
Full status	diverga_project_status()	Project state + checkpoints + decisions
Check prereqs	diverga_check_prerequisites(agent_id)	Verify agent can proceed
Record decision	diverga_mark_checkpoint(cp_id, decision, rationale)	Record and auto-update priority

Auto-Update Behavior

Priority context is automatically updated when:

• A checkpoint is marked via diverga_mark_checkpoint()
• Format: Project: {name} | Paradigm: {paradigm} | RQ: {question} | ✅/❌ checkpoints | Last: {decision}
• Maximum 500 characters, stored at .research/priority-context.md

Compression Recovery

When context window is compressed:

1. Call diverga_priority_read() to recover essential project context
2. Call diverga_checkpoint_status() to see checkpoint state
3. Call diverga_project_status() for full project details

3-Layer Context System

Layer 1: Keyword-Triggered (자연어 감지)

When researcher asks "내 연구 진행 상황은?" or "What's my research status?", automatically load and display context.

Auto-Detection Keywords:

• "my research", "연구", "research", "progress", "진행"
• "where was I", "continue", "다시", "어디까지"
• "what stage", "현재 단계", "stage", "지금"

Response Pattern:

1. Detect keyword match
2. Load .research/project-state.yaml
3. Display current stage and progress
4. Show pending checkpoints
5. List available next actions

Layer 2: Task Interceptor (에이전트 호출)

When Task(subagent_type="diverga:*") is called, automatically inject full research context and checkpoint instructions.

Injection Process:

1. Detect diverga: prefix in subagent_type
2. Read .research/project-state.yaml
3. Read .research/checkpoints.yaml
4. Inject context into agent prompt
5. Add checkpoint validation wrapper
6. Execute with full research awareness

Context Injected:

# Automatically included in agent prompt
research_context:
  project_name: "[from project-state.yaml]"
  current_stage: "[from checkpoints.yaml]"
  research_question: "[from project-state.yaml]"
  methodology: "[from project-state.yaml]"
  decisions: "[from decision-log.yaml, last 10]"
  pending_checkpoints: "[from checkpoints.yaml]"

Layer 3: CLI (명시적 요청)

Run /diverga:memory context --verbose for full detailed state.

Available Flags:

• --verbose - Show full decision audit trail
• --archive - Include archived stages
• --decisions - Show decision log only
• --checkpoints - Show checkpoint status only
• --format json|yaml|text - Output format

/diverga:memory migrate --dry-run

Output:

MIGRATION CHECK: v6.8 → v7.0
═════════════════════════════════════

Found v6.8 project structure detected:
├─ old_decisions.log (47 entries)
├─ old_checkpoints.txt (basic format)
└─ old_sessions/ (8 files)

MIGRATION PLAN
├─ ✓ Convert decisions to YAML format
├─ ✓ Upgrade checkpoint structure (add levels)
├─ ✓ Import session history
├─ ✓ Create missing metadata fields
└─ ✓ Generate amendment chain analysis

Ready to migrate. Use: /diverga:memory migrate

Execute Migration

/diverga:memory migrate

Output:

MIGRATION IN PROGRESS
═════════════════════════════════════

✓ Imported 47 decisions
✓ Upgraded checkpoint structure
✓ Analyzed amendment history
✓ Imported 8 session records
✓ Generated project-state.yaml
✓ Validated checkpoint linkage
✓ Created archive/baseline/ structure
✓ Backed up original files to .backup/

MIGRATION COMPLETE
═════════════════════════════════════
Project upgraded to v7.0
Old files backed up in: .research/.backup/v6.8/
Ready to continue research workflow.

Backward Compatibility

v7.0 maintains read-only compatibility with v6.8 files:

• Can read old decision logs
• Can display old checkpoint format
• Cannot write to old format
• Must run migration for full functionality

Integration with Research Coordinator

Memory system integrates with all Diverga agents (A1-H2) to provide:

Auto-Context Injection for Agents

When delegating to research agents:

# Without explicit context injection (system does it automatically)
Task(
    subagent_type="diverga:A2-HypothesisArchitect",
    prompt="Help me develop hypotheses for my research"
)

# Memory system automatically:
# 1. Loads .research/project-state.yaml
# 2. Loads .research/decision-log.yaml
# 3. Injects into agent system prompt:
#    - Current research question
#    - Methodology selection
#    - Prior decisions made
#    - Pending checkpoints
# 4. Executes with full context

Checkpoint Enforcement in Agent Execution

Agents automatically:

• Check pending REQUIRED checkpoints before starting
• Validate checkpoint prerequisites
• Record new checkpoints when appropriate
• Update session context
• Log decisions with audit trail

Session Continuity

When researcher returns later:

User: "Let's continue my research on AI in education"

Memory System:
1. Detects keyword trigger
2. Loads last_session from project-state.yaml
3. Displays: "Welcome back! Last session: Feb 3, 14:30"
4. Shows: "Next checkpoint: CP_SCOPE_DEFINITION"
5. Suggests: "Continue with scope definition discussion?"

Advanced Features

Dependency Chain Tracking

Memory system automatically detects and validates checkpoint dependencies:

dependencies:
  CP_PARADIGM_SELECTION:
    requires:
      - CP_RESEARCH_DIRECTION  # Must be completed first
    unlocks:
      - CP_THEORY_SELECTION
      - CP_VARIABLE_DEFINITION
      - CP_METHODOLOGY_APPROVAL

  CP_DATABASE_SELECTION:
    requires:
      - CP_METHODOLOGY_APPROVAL
    unlocks:
      - CP_SEARCH_STRATEGY
      - CP_SCREENING_CRITERIA

Baseline Preservation

Research baselines (literature reviews, theoretical frameworks) are immutable:

.research/baselines/
├── literature/
│   └── key_studies.yaml        # Immutable snapshot
├── methodology/
│   └── frameworks.yaml         # Immutable reference
└── framework/
    └── theories.yaml           # Immutable collection

Changes are tracked in changes/current/ while baselines remain stable.

Cross-Project Learning

After project completion, memory system extracts learnings:

/diverga:memory extract-learnings

Creates shareable artifact for future projects:

• Common decision patterns
• Checkpoint shortcut sequences
• Timeline estimates
• Lessons learned

Performance and Limits

Metric	Limit	Notes
Max decisions per project	1000	Archive older decisions if needed
Max sessions per project	500	Session history available via archive
Context injection latency	<100ms	Cached for performance
Maximum project lifespan	10 years	Can archive and restore old projects

Privacy and Security

• All project data stored locally in .research/
• No cloud sync unless explicitly configured
• Decision audit trail is non-repudiation certified
• Checkpoint timestamps are tamper-evident
• All modifications tracked in git history (if repo enabled)

---

Summary

Diverga Memory System v7.0 enables researchers to:

✓ Persist research context across sessions without manual setup ✓ Track all decisions with immutable audit trail and amendment support ✓ Enforce research rigor through checkpoint system with dependency validation ✓ Integrate with agents automatically for context-aware research support ✓ Maintain research quality through baseline preservation and change tracking ✓ Scale research projects from single-investigator to multi-year team efforts
