The gate replayed every commit through the from-scratch tree builder three times to predict what the conversion itself measures, and on pkgsrc that was 14 of 26 hours before a byte was written. The conversion writes a new project beside an untouched source, so the honest evidence is the converted store: the summary now reports its bytes against the flat source's. The partition parameter comes from --k or the tip sweep; a history no k partitions is refused, as 'submanifest enable' refuses it. 'zit submanifest analyze --replay-all' keeps the model for anyone who wants it first. Closes zit#129. check-in: 04d944c1dd user: dmestas tags: trunk
