← search-empty / predicate-empty — distinguish zero reported matches from a scoped absence claim
Measurement result
Current-tokenizer cost (Δ, worst tokenizer)
-18.666666666667 tokens on the named current tokenizer(s) compared with standard English
Reported interval: -30 to -10
No server-replayable interval attestation is retained for this row; these reported bounds do not acquire settlement weight merely by overlapping.
The result is on the helpful side of this metric's neutral point.
