No, I think the moment she "embarked on a quest to refactor the application" she graduated from vibe-coding to coding.
But I think the fact that she's managing without even knowing (or caring to know) the language the code base is written in means that it isn't really "coding" either.
She's doing the application architecture herself without really needing to know how to program.
I've copy-pasted snippets for tools and languages that I do not know. Refactored a few parameters, got things working. I think that counts as programming in a loose sense. Maybe not software development or engineering, but programming.
The first non-toy program I ever wrote was in BASIC, on ZX Spectrum 48, and although I don't have it anymore, I remember it was one of the shittiest, most atrocious examples of spaghetti code that I've ever seen in my life.
Everyone starts somewhere.
I was picking apart other peoples' javascript to see how it worked years before I was taught anything about coding in a formal setting.
Also I feel old now, I think we _just_ did XP at a company, but that was almost a quarter century ago :D
