>I am interested to know the distinction between "production-ready" and "science-ready" code.
In general, scientists don't care how long it takes or how many resources the code uses. It is not a big deal to run a script for an extra hour, or use up a node of supercomputer. Extravagent solutions or added packages to make the code run smoother or faster is only wasting time. It speed/elegance only really matters when you know the code is going to be distributed to the community.
Basically scientists only care if the result, is true. If the result it outputs is sensible, defensible, reliable, reproducible. It would be considered a dick move to criticism someones code, if the code was proven to produce the correct result.
