The worker reads the XOVER reply's text directly: fields by position, the owner from the Xref without arrays (crossposts leave before any subject parsing), a subject parsed once per file (cached without its segment counter), a file's details as one shared object, dates as numbers. Garbage collection had been ~22% of the time. Same results as parseOverviews + segmentFromHeader on 800k real lines. edge:bench (one core): boneless 137k → 193k headers/s (CPU 21 → 12.8 s), ath (2013) 143k → 303k; peak RSS 1.15 / 0.87 GB.
