Verified execution runtime unifying state, persistence, and replication. http://git.yeowoo.org/pure/atom?h=master 2026-09-30T16:59:47Z 2026-09-30T16:59:47Z eunhhu necpition205@gmail.com 2026-09-30T16:59:47Z urn:sha1:402c19311b247889b36ff3be834d9fab19555af7 016's second stage passed its criterion: six interleaved pairs against ee21aec gave TPC-C (RAM, W=1) -0.6% at the median and the bank's queries 0.0% to +2.2%, no run interfered. The ranks query was slower all six times, and chasing it showed that on this Pi timing cannot separate 1-3%: two servers asked in turns disagree with themselves (ee21aec to e02bfc9 +1.6%, e02bfc9 to 481642f -1.2%, ee21aec to 481642f +2.8%), and a query whose instructions grew 0.6% ran 3.5% faster. Instructions do not move so: pcount.c counts the server's user-mode instructions with perf_event_open (no perf here), and psample.c samples where they go. ranks had grown 0.4% in instructions (the rest was where code and data landed), per_branch 3.6% and tables 20 instructions a row, which 07047c3 halved. The six pairs of 07047c3 were interfered (another session's build, load 4-12) and are kept apart, unused.
