Nice :) fixed

There's something off in the javascript random tests. thought is always passed as a number, not a string, and every test expects ''

I'll republish first of April 2025.

Thanks, I'll combine both other ideas, without extreme performance requirements.

Great concept and very well-presented. I think parts II & III could be combined into a single kata (one that I look forward to trying), although the more performance-hungry among us might demand a separate kata devoted only to that.

You are nothing if not thorough ;) Appreciate the heads-up.

[notification] invalidated: the inventory in the constructor now also requires a deep copy

Got it, thanks.

If you have the potion in stock and somebody wants it, you provide it. However, when you need to construct one, and the alchemist does not know how to compose it, you cannot compose it. This is a case I will add to sample tests.

I'm failing around 3% of the random tests. It's always on a potion that was provided to the Apprentice in the constructor but which is later unrecognized by the Alchemist in a process request. Are we meant to ignore them?

Superb. Reminiscent of Flotsam and equally fun to solve. Map ideas incoming :)

... furthermore, why in the world is each string in TABLE inside a list?
