030: the numbers from one build (the runtime 40,847 and the hand path 813, cycles 15,735 and 348, beside Vega's 251 and 93; other builds 1-2% apart) and 602 named as the substituted algorithm (373 cycles); 9.43x said to be the emitted chain's factor, the executor's share step 1's first measurement; 009's tension stated once (sparse updates in the log's delta, whole numbers zigzag there: a second shape, the cheaper one); the caveats of 047 together; model.py's import where imports goHEADmaster
