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
