A bit of a fun puzzle, although I'm still a bit confused on what `w` does, if anything (Given the 0007 hint, it feels like "w" might just form part of a command), but it made 0004 hard to figure out, eventually leading to me getting part of it then figuring out similar words that would fit!
Thanks for playing, and I'm glad you had fun with it!
w is not in fact anything, and 0004 is where I've seen a few people getting stuck, so I probably did not design it very well. It has a lot of overlapping rules and it's not that clear what order you're supposed to do them in, so maybe it would have been better if there was a previous lock that taught you about the solve order unambiguously.
"Finding part of the word and then guessing the rest" is very much intended though, as a sort of release valve for people who don't find the logic very clear!
Ohh, interesting! At first I thought it was a "rulechange", as in it overrode the existing rule in the 'command' it was part of, but then I wasn't quite sure when I saw it in some of the hints!
Hopefully this gives you some insight into how 'w' is being perceived and what's going on with it, but I know puzzle design can be really tricky
