Three talks in the beamer reference set render one page against tectonic's 9, 5 and 3. They call macros from a preambule.sty the corpus does not ship, and the difference is what happens to the arguments: LaTeX's own error recovery reports Undefined control sequence and then typesets {a}{b} as text, while this engine drops the command and its likely argument block (skipUndefined, engine.go).
Matching LaTeX looked like free fidelity — those three talks alone are 14 of beamer's 42-page error. Measured, it is the opposite.
Measured — keep the arguments instead of swallowing them

beamer's glyph count quadruples and its page error is eight times worse: a class calls its own undefined internals with large arguments — templates, overlay specifications, colour blocks — and typesetting those floods every page with machinery. 183 of the 200 talks repaginate.
The heuristic in skipUndefined is therefore not a convenience but load-bearing, and the three talks stay as they are: their content cannot be recovered without the package they name. Recorded so the experiment is not repeated.
