Conversation
Two Chrysaor (Pegasus for Android) samples joined the malware corpus, so score_adjustment retrained the whole rule pool against it. This updates the score field of 272 rules. No rule content changes. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Two Chrysaor samples — MITRE S0316 Pegasus for Android — joined the malware corpus, so
score_adjustmentretrained the whole rule pool against it. This syncs the resulting weights.scorefieldClass.getName+Method.invoke) trained to -0.70. Three hand-written candidates aimed at gaps this family exposed were also rejected on their malware-to-benign L5 ratio (prevalence-normalised 0.60, 0.38 and 1.62 against a 1.5 bar) — dynamic class loading and runtime broadcast registration turn out to be at least as common in benign apps.The accompanying analysis report is submitted separately to quark-engine.
