Every row read "no repeat → no repeat" because the label only ever
tracked one knob — the block-repeat spec — so a comparison where
anything else changed, or nothing did, described itself as unchanged and
told you nothing about what it compared.
sample() now snapshots its scalar arguments (locals() at the top IS the
argument list, so no name list to go stale), and each row keeps the DIFF
against the previous run. The row titles itself:
h3_block_repeat: — → 40 sharper — +204% detail, on existing edges
nothing changed stable — two identical runs match, so a
real A/B can be trusted
seed 111 → 222 different seed — not comparable
The "nothing changed" case is the valuable one and was previously
unreachable: two identical runs measure how much generation varies on
its own. If that comes back unstable, no A/B on the setup means
anything, and the row says so instead of letting every later comparison
quietly inherit the noise.
