From 1adc882f6d91983fcd5d907644f17590a2acbcd9 Mon Sep 17 00:00:00 2001 From: CyberSecurityUP Date: Wed, 23 Sep 2026 01:18:14 -0300 Subject: [PATCH] feat(decision): wire 3 high-value System One decisions (backend = TypeSafe or Laya) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The three fragile heuristics now get a calibrated second opinion when a decision backend is configured. All go through TypeSafe::from_env(), so they work identically with hosted TypeSafe or local Laya (--decision-backend), and the run banner names the active backend. Deterministic behaviour is unchanged when no backend is set or --typesafe off. - typesafe.rs: three helpers — same_finding (Noul), response_origin (Choice) and is_prompt_injection (Noul). - Dedup grey zone (pipeline finish): a fixed 0.4 Jaccard cannot settle near-duplicates; merge_grey_zone_dupes asks a calibrated Noul on every same-endpoint/CWE pair scoring in the 0.25..0.40 band and merges the ones it calls the same bug. - WAF origin (poc.rs): header signatures are ambiguous; before dropping a PoC as edge-answered, the backend gets the deciding vote — only bail if it also judges p(application) < 0.5, so a real finding is not discarded on a false edge. - Prompt-injection (pipeline probe): the keyword matcher over-flags legit pages that merely mention "ignore instructions"; a calibrated Noul confirms real manipulation before raising the neutralised-injection notice. 383 tests.
