/tmp is tmpfs: the 2026-10-18 IOMMU reboot deleted /tmp/halogen-eval mid-A/B and
the off-arm numbers nearly went unreproducible. One command restores the corpus
(wikitext-2 raw test, blanks dropped, 2891 lines / 1287656 B -- the byte count is
the identity check because battery.py sizes haystacks in characters), the 512px
probe PNG, and battery.py itself; WARM=1 also pre-reads the 51.2 GB n-gram table
so a cold page cache cannot masquerade as a measured regression. Must run through
a login shell: uv lives in ~/.local/bin.
