Abstention on No-Tool Queries (cactus-needle 2.0.5)

Date: 2026-08-17
Hypothesis

When no relevant tool exists, the model abstains rather than forcing a false-positive call, and near-miss catalogs (a semantically close but wrong tool present) produce more false calls than unrelated catalogs. Confidence does not reliably separate correct abstentions from false ones.
