Type mismatch: rows - inserted is already i64 (since rows is i64 and inserted is i64), so the cast to i64 is unnecessary and could mask potential issues. Remove the cast.

Type mismatch in range: take is i64 but range expects usize. Use take as usize in the range or change the loop to avoid the type conversion.

Code Review
This pull request introduces valuable tooling and documentation, including a production preflight checklist, a merge report addendum, and a benchmark script. The documentation is clear and the checklist is comprehensive. I've provided a couple of suggestions for the new benchmark script to improve its robustness and error handling.

The current argument parsing for --rows silently ignores invalid input by using unwrap_or. This can lead to the script running with unexpected parameters without any warning, which can be confusing for the user. It's better to fail fast and inform the user of the incorrect input. For more robust and user-friendly CLI argument parsing in the future, you might consider using a crate like clap.
| "--rows" => if let Some(v) = args.next() { rows = v.parse().unwrap_or(rows); }, | |
| "--rows" => if let Some(v) = args.next() { rows = v.parse().expect("Invalid value for --rows: must be an integer"); }, |

Using Decimal::from_f64 followed by .unwrap() can be risky. from_f64 returns None for non-finite values (like NaN or infinity), which would cause a panic. While rng.gen_range is unlikely to produce these, it's more robust to avoid floating-point conversions when creating Decimal values. You can construct the Decimal from integers to ensure precision and safety.
| let amount = Decimal::from_f64(rng.gen_range(1.0..500.0)).unwrap(); | |
| let amount = Decimal::new(rng.gen_range(100..50000), 2); |
