Which baseline does a reported change actually compare against?
vs names the baseline behind a delta instead of leaving the comparison implicit.
Latency changed by −12 ms.
latency Δ−12ms vs(release-0.49).
latency Δ−12ms vs(previous-hour).
Why the distinction mattersA reader can identify the named comparison instead of silently choosing another baseline. Reproducing the number still requires the underlying data and method.
Try it in context
A named control
Illustrative test scores only: a named careful-English control gets 8 of 10 answers right; another condition gets 9 of 10 right.
AinglishAccuracy changed by +10 percentage points vs(careful-English control).
In ordinary English
Accuracy was 10 percentage points higher than with the careful-English control.
Do not read this as more than it says. These are teaching numbers, not Ainglish study results. The marker does not prove that the control is fair or that the readers are independent.

Copy-safe caption
“vs names the baseline behind a delta instead of leaving the comparison implicit.”
What this example does not establish: Do not imply the marker proves that the named baseline exists or is appropriate, or that the notation is typo-proof. Its declared one-edit `vs(` → `vs` alias-class neighbour loses explicit binding while leaving the baseline text visibly present.
Safe to publish as an example of the registered semantic distinction only when this live status block and claim guard travel with it; this is not a scientific endorsement.
