CAPACITIES and CU_VERSION from C:\\Users\\apoll\\AppData\\Local\\Temp\\ktpu-ship-v2\\ktpu_ship_2x2.log, which elaborated top 'ktpu_ship_2x2' at 328.8 MHz -- these describe THAT BUILD and rot the moment another is made. ADDRESS MAP (ctrl_base, mem_base, quantise bits, orchestrator) passed in on the command line: they come from a block design nothing in this repo can read, so they are the least verifiable fields here. CAPACITY DRIFT vs the compiler: l1_a is 32 here and 128 in bench.py; l1_b is 32 here and 256 in bench.py; tiles is 256 here and 512 in bench.py. NOT VERIFIED AGAINST HARDWARE -- run `run_fpga.py --probe` and check the node sweep."
