PCC measured. pulsar matched OSCB. xz is still ahead.
Official Silesia 12. Whole files. md5-matched to Mahoney’s table. Raw 211,938,580 bytes. DECODE_OK on every keep, or it does not count. gzip, bzip2, and xz are opponents, not occupants.
PCC wrote 51,498,645. 12/12 restored.
pulsar 2.5.0 wrote 55,745,438. That matches OSCB. 12/12 restored.
gzip-9 on the same corpus is 67,631,990. bzip2-9 is 54,506,769. xz-6 is still smaller than PCC — about 49.4M. We do not claim #1.
An old AWARE+XZ1 line at 47.7M is retired. It occupied host xz. It is not a product spec, and it is not on this board.
champ, best, and PCC stay blank until they are 12/12. Dual-licensed: open terms, or a paid grant. Live board: https://www.slidphilabs.com/silesia.
