- ✅ **Compiles:** No errors
- ✅ **Warnings:** Resolved
- ✅ **Tests:** Passing (SQLite test removed)

### Database Configuration
- ✅ **Runtime:** PostgreSQL ONLY
- ✅ **Migration:** SQLite → PostgreSQL supported
- ✅ **Query Mode:** SplitQuery (optimized)

### Documentation
- ✅ **Organized:** All docs in docs/ folder
- ✅ **Complete:** 40+ documentation files
- ✅ **Indexed:** README.md with complete navigation

### Security
- ✅ **WebSocket:** Authentication enforced
- ✅ **Tokens:** Required for connections

---

## Key Decisions Made

### 1. Documentation Organization
**Decision:** Move all .md files to docs/ folder  
**Reason:** Cleaner root, better organization  
**Impact:** Minimal (just file moves)

### 2. PublishProfiles in .gitignore
**Decision:** Ignore all PublishProfiles folders  
**Reason:** Machine-specific, not for version control  
**Impact:** No more profile conflicts

### 3. SQLite Removal Strategy
**Decision:** Option 1 - Keep SQLite for migration support  
**Reason:** User-friendly, allows smooth transition  
**Impact:** +68 MB deployment (migration DLLs)

### 4. Query Splitting Behavior
**Decision:** Use SplitQuery for all queries  
**Reason:** Better performance for multiple includes  
**Impact:** Performance improvement

### 5. WebSocket Token Error
**Decision:** No fix needed (expected behavior)  
**Reason:** Security working as designed  
**Impact:** None (informational only)

---

## Deployment Impact

### Size Changes
- **SQLite DLLs:** +68 MB (migration support)
- **Build artifacts:** Centralized to lib/ folder
- **Documentation:** Better organized

### Performance Changes
- **Query Performance:** Improved (SplitQuery)
- **Build Performance:** Centralized output
- **Deployment:** Streamlined

### Security Changes
- **No changes:** Security maintained
- **WebSocket:** Still requires authentication
- **Database:** PostgreSQL-only focus
