How Claude Web tried to break out its container, provided all files on the system, scanned the networks, etc

Originally wasn't going to write about this - on one hand thought it's prolly already known, on the other hand I didn't feel like it was adding much even if it wasn't. But anyhow, looking at the discussions surrounding the code leak thing, I thought I as well might. So: A few weeks ago I got some practical experience with just how strong Claude can be for less-than-whole use. Essentially, I was doing a bit of evening self-study about some Linux internals and I ended up asking Claude about something.
