Sixty-seven failures arrived with their reasons scattered across thousands of log lines, and one broken script takes down every file referencing it, so what matters is seeing them together. Collect a reason per file and print them as one block; carry the real cause up through includes and referenced scripts rather than naming the file that referenced them. WOWEE_LOAD_FRAMEXML now implies WOWEE_LUA_API_FALLBACK. FrameXML cannot get through its own load without it, so two switches where one is useless alone was only a way to be handed a wall of failures for setting the obvious one. The compile checker counted a file it could not parse as neither pass nor fail, reporting a clean run over files that never loaded.

// Does the Lua we generate from FrameXML actually compile?

// The unit tests check the shape of the output against cases someone thought

// of. This asks Lua itself about every real file, which is a different and
|
|
// harsher question — it found an empty function attribute emitting
|
|
// SetScript("X", ), and temporaries running into Lua's limit of 200 locals per
|
|
// function. Neither degrades: the whole chunk refuses to compile.
