17/18 now fixed. A red-team of the three accepted findings showed #9 and #13
rested on a circular premise (each was the other's "safe fallback") and S7's
written rationale was wrong (signing exercises the same modexp Marvin targets).
#9/#13 closed; S7 accept retained for the corrected reasons + amplifier hardened.
