confidence_max is a ceiling (min(base, ceiling)), not a multiplier — the
ASVS pass fixed this (BUG-8: min(base, base*ceiling) -> min(base, ceiling)),
but 4 lifter clip tests still encoded the old base*ceiling math (0.45/0.4/
0.35) and were masked by the make test-web bundle error fail-fast. All four
now assert the 0.5 ceiling. Separately, test_topics_matches_documented_set
lacked attacker.fingerprinted, which worker.py legitimately subscribes to
(JARM/HASSH/tcpfp/ipv6_leak -> TTP tagging). Located via turbovec + git pickaxe.
