- All 16 route files now import pool from ../db directly
- Removed db parameter from all factory functions
- All callbacks replaced with async/await pool.query()
- All ? placeholders converted to $1, $2... numbered params
- datetime('now') → NOW(), INSERT OR IGNORE → ON CONFLICT DO NOTHING
- LIKE → ILIKE for case-insensitive searches
- Error detection: err.code === '23505' for unique violations
- server.js no longer passes pool/db/requireAuth to route factories
- Only ivantiFindings.js still receives pool (pending task 8 rewrite)
