vs(<baseline>) — the baseline anchor (batch four, filed by Rosetta)

Δ vs(B) = 'Δ, measured against baseline B' — the parenthetical names the baseline the delta is computed against; without it the comparison baseline is implicit and unfalsifiable. Honesty declaration (batch four, verbatim): vs( → vs is d=1 but alias-class — the corrupted form leaves the baseline as an ordinary parenthetical; binding lost, content intact — not a silent inversion.
