## Achievements by Category

### 1. Data Import & Migration [OK]

**Imported Conversations:**
- 589 files imported (546 from imported-conversations + 40 from guru-connect-conversation-logs + 3 failed empty files)
- 60,426 records processed
- 31,170 messages extracted
- **Dataforth DOS project** now accessible in database

**Tombstone System:**
- Import script modified with `--create-tombstones` flag

## System Architecture

### Current Flow (Fixed)

```
User Request
    ↓
[DATABASE-FIRST QUERY]
    ├─→ Query conversation_contexts for relevant data
    ├─→ Use FULLTEXT indexes (fast search)
    ├─→ Return compressed summaries
    └─→ Inject into Claude's context
    ↓
Main Claude (Coordinator)
    ├─→ Check if task needs delegation
    ├─→ YES: Delegate to appropriate agent
    └─→ NO: Execute directly
    ↓
Complete Task
    ↓
[AUTO-SAVE CONTEXT]
    ├─→ Compress conversation
    ├─→ Extract tags automatically
    ├─→ Save to database
    └─→ Create tombstone if needed
    ↓
User receives context-aware response
```

### Database Schema

**conversation_contexts** (Main table)
- 710+ records
- 11 indexes (6 original + 5 performance)
- FULLTEXT search enabled
- Average 70KB per context (compressed)

**context_tags** (Normalized tags - NEW)
- Separate row per tag
- 3 indexes for fast lookup
- Foreign key to conversation_contexts
- Unique constraint on (context_id, tag)

## How to Use the System

### Quick Start

**1. Recall Context (Database-First):**
```bash
curl -H "Authorization: Bearer $JWT" \
  "http://172.16.3.30:8001/api/conversation-contexts/recall?search_term=dataforth&limit=10"
```

**2. Save Context (Manual):**
```bash
/snapshot "Working on feature X"
```

**3. Create Checkpoint (Git + DB):**
```bash
/checkpoint
```

### Common Workflows

**Find Previous Work:**
```
User: "What's the status of Dataforth DOS project?"
Claude: [Queries database first, retrieves context, responds with full history]
```

**Save Progress:**
```
User: "Save current state"
Claude: [Runs /snapshot, saves to database, returns confirmation]
```

**Create Milestone:**
```
User: "Checkpoint this work"
Claude: [Creates git commit + database save, returns both confirmations]
```
