- Linux system checks (read-only from /proc, no auth needed):
* shmmax, shmall kernel limits
* Available RAM check
- PostgreSQL auto-tuning:
* max_locks_per_transaction scaled by BLOB count
* maintenance_work_mem boosted to 2GB for faster indexes
* All settings auto-reset after restore (even on failure)
- Archive analysis:
* Count BLOBs per database (pg_restore -l or zgrep)
* Scale lock boost: 2048 (default) → 4096/8192/16384 based on count
- Nice TUI preflight summary display with ✓/⚠ indicators
