Initialize transaction with flags\n2. Add targets (packages to install/remove)\n3. Prepare (resolve dependencies, check conflicts)\n4. Commit (execute operations)\n5.

Verification levels:\n- `Never` - Skip verification\n- `Optional` - Verify if signature exists\n- `Required` - Fail without valid signature\n\n### AUR (Arch User Repository)\nCommunity-maintained package build scripts (PKGBUILDs) not in official repos.
