• Pooled run_dada is not uniform: occupancy climbs 22 -> 42 cores across a run, and the serial fraction is concentrated in the early rounds

• b_compare's map is slower on reused memory than on freshly-faulted memory (~11-16% of busy); mechanism unresolved, no perf counters available

• b_compare slower per comparison under the #139 carry on soil 16S (likely #151's buffer-reuse effect); re-measure on current main with length-normalized input
