Constraint Programming (2020)
There are quite a few out there. I played with gecode as well as https://choco-solver.org/ which I found intuitive and fun to use.

How to Corrupt an SQLite Database File
I personally doesn't get surprised by POSIX to consider it's violating this "least surprise" amount.
Instead, for example Java has given me much more surprises, and at catastrophic levels. I was using Choco Solver [0] back in the day, and I created two instances of it, attached to different classes. Which is perfectly normal, right?
Somehow they've cross linked between these two instances, affected the results they have computed, and created persistent memory leaks which needed system reboots to claim back. Java should be immune to that, but no.
Preventing that needed to run only one instance of Choco, which limited my performance greatly. Luckily, the system had a queue/consumer structure, so running only one didn't need extensive changes.

Constraint Programming: Solving Sudoku with Choco Solver library
Sudoku is one of these types of problems, but it has very simple rules, so it’s a nice playground to try out different ways to solve graph colouring problems. This post outlines a solution using constraint programming with choco solver.

Planner programming blows my mind
Are the commercial offerings you mentioned better than TimeFold? [0] (formerly known as OptaPlanner before the main developers forked it)
TimeFold's heuristics-based approach makes fast solutions to even highly-complex scenarios within the reach of anyone who can write Java expressions that evaluate to true when constraints are satisfied.
