REJECTED. Verification script caught math mode errors ('Missing $ inserted') in `lecture-03-yt.log` and `lecture-07-yt.log`, and an overfull hbox in `lecture-15`. This is likely due to unescaped underscores '_' or dollar signs '$' or '&' in your JSON content not being escaped by your LaTeX assembly script. Fix your script, regenerate, and recompile.
