tripwire — vulnerability matrix

A fail-closed action gate measured against a 44-class adversarial corpus. No high-stakes action runs without an explicit matching policy rule; ambiguity always refuses. Every number below is measured from a committed, seed-pinned run — not asserted.

Delta vs. the undefended baseline: 100.0% gated vs. 0.0% ungated (n=108). The baseline proves the attacks are real; the gate is what stops them.

Two defense surfaces, reported separately — never conflated into one score: action authorization 87/87 (the by-construction guarantee — no high-stakes action without an explicit matching rule, property-tested, every decision in the tamper-evident audit log) · output disclosure 21/21 (detection-based defense-in-depth — a shape filter is best-effort and bypassable by obfuscation; the guarantee deliberately lives at the action layer, where it can be proven).

Honesty. 100% gated defense is the expected correct behavior of a deny-by-default gate against attacks that all violate the reference policy — not a surprising score. The value is the by-construction guarantee (property-tested) plus the tamper-evident audit trail. A permissive custom policy can still authorize a harmful action. The 8 N/A classes are model-behavior / infra classes a deterministic action-gate mock cannot honestly exercise; they are greyed and excluded from every denominator.
