Nine alternating-order pairs after one warmup per mode. Fresh process per pass. One module stream at a time, fully forced before its timer. Sum of per-module elapsed object-output time. GHC -O2 backend and harness, single capability, -A16m. Includes output writes to warm filesystem cache, without fsync. Text path includes printing and one Clang integrated assembler invocation per nonempty module. Excludes front-end work, LIR parsing, instruction selection, preflight GC, harness startup, linking and validation.",
