   🎯 APPROACH: Trait-Based Abstraction

      Database Trait (abstract)
           ↓
           ├─→ SqliteDatabase (current code)
           └─→ SurrealDatabase (new implementation)

      Benefits:
      ✅ Zero breaking changes
      ✅ Both backends coexist
      ✅ Configuration-driven selection
      ✅ Easy to test (mock implementations)
      ✅ Future-proof (add PostgreSQL, MongoDB later)

   ⚙️ CONFIGURATION SYSTEM

      # SQLite (default, embedded)
      [database]
      engine = "sqlite"
      sqlite_path = "~/.local/share/core/workspace.db"

      # SurrealDB (cloud-ready, optional)
      [database]
      engine = "surrealdb"
      [database.surrealdb]
      url = "ws://surrealdb-server:8000"
      namespace = "syntaxis"
      database = "projects"

   🔄 MIGRATION TOOL (Built-in)

      # Show current database
      workspace database status

      # Migrate with backup
      workspace database migrate \
        --from sqlite --to surrealdb --backup

      # Dry run to preview
      workspace database migrate \
        --from sqlite --to surrealdb --dry-run

      # Rollback if needed
      workspace database migrate --rollback

   ╚════════════════════════════════════════════════════════════════════════════╝

   1. GRAPH-NATIVE PHASE TRANSITIONS
      Before (SQLite):  3 JOINs needed
      After (SurrealDB): project:123 -> transitioned_to -> *

   2. REAL-TIME DASHBOARD UPDATES
      Before: Poll every 5 seconds (wasteful)
      After: WebSocket push (instant, real-time)

   3. BUILT-IN AUDIT TRAIL
      Before: Manual activity_logs table
      After: SELECT * FROM projects VERSION AT <date>

   4. FLEXIBLE TOOL CONFIGURATIONS
      Before: JSON strings to parse
      After: Native document objects

   5. DISTRIBUTED/CLOUD-READY
      SQLite: Single file (embedded only)
      SurrealDB: Cloud-native, distributed

      Then: SURREALDB_MIGRATION.md (30 min)
      Study: SURREALDB_EXAMPLE.rs (code review)
      Review: SURREALDB_COMPARISON.md (features)

   2. ⚙️  EVALUATE FOR YOUR NEEDS
      - Single user or team?
      - Need real-time updates?
      - Cloud deployment planned?
      - Graph queries important?

   3. 📋 DECIDE ON APPROACH
      Option A: Keep SQLite only (current)
      Option B: Add SurrealDB support (recommended)
      Option C: Both backends with configuration

   4. 🎯 PLAN IMPLEMENTATION
      - Assign resources
      - Estimate timeline
      - Create feature branch
      - Start Phase 1 (trait definition)

   ╚════════════════════════════════════════════════════════════════════════════╝

   ✅ YES, implement SurrealDB support because:

   1. ✅ Architecture is clean (single persistence module)
   2. ✅ Natural fit for domain (graph-based phases/tasks)
   3. ✅ Trait-based approach = zero breaking changes
   4. ✅ Can be incremental (SQLite default, SurrealDB optional)
   5. ✅ Medium effort (40-50 hours, manageable)
   6. ✅ Significant benefits for multi-user/real-time use

   Approach:
   - Keep SQLite as simple default (current behavior)
   - Add SurrealDB as advanced option
   - Configuration-driven selection
   - Users choose what fits their needs

   Result: Best of both worlds without disruption
