correct: baseline 3/7   xerj 6/7

-- tokens over jointly-correct tasks only --
   baseline 265 tok   xerj 232 tok   -> XERJ uses 1.14x FEWER tokens

-- corpus composition --
   53.1 KB total; 49.0 KB searchable prose/code (92.3%)
   This is the regime where retrieval savings appear: grep's candidate
   set grows with the corpus; ranked search returns one passage.
