Answer / Verify / precision–coverage experiment

Choose how much evidence TOMX needs before it serves an answer.

Cautious, balanced, and chatty run side by side on the same answerable question and the same candidate-absent question. Switch the absence gate off to observe the counterfactual. Precision is never shown without coverage (served rate), because serving fewer rows can raise precision.

The active driver did not expose a curated row in this class, so this surface does not manufacture one.

Aggregate evidence / banked

The precision–coverage pairs are one fixed probe, not these two examples.

Interpretation limit These four recorded settings show a measured trade-off on relational-hop rows. They do not prove that every unsupported input is detected. The deployed TX and RAG arms run without the TOMX abstention gate; no broader architectural claim is inferred here.
ANSWER · VERIFY

Shows: cautious, balanced, and chatty TOMX decisions on the same answerable and candidate-absent examples, plus banked precision paired with coverage for every displayed operating point. Does not show: perfect unsupported-input detection or a benchmark derived from two examples. Live decisions are anecdotes; aggregate pairs are a dated, fixed-probe family-0 result.
