Every patch now ships with a runnable benchmark verifying complexity claims:
- bleach/unit/test_bleach_cwe1333.py: length guard truncates 1001-char adversarial
input to 1000 chars (removes '@' tail), gauntlet matches fast (<0.5s)
- salt/unit/test_salt_cwe1333.py: ThreadPoolExecutor timeout wrapper tested at N=20
adversarial, GIL behavior documented
- ansible/unit/test_ansible_cwe1333.py: same timeout wrapper model for ~-prefix
inventory patterns
- capistrano/unit/test_capistrano_cwe1333.rb: Regexp.timeout= / Timeout fallback
guard for host/role filter patterns
- puppet/unit/test_puppet_cwe1333.rb: RegexGuard.safe_compile timeout for all
three Puppet regex call sites (match(), =~, PRegexpType)
- katago/unit/test_katago_cwe407.cpp: bool seen[] bitset vs O(N*k) linear scan;
23x speedup at chain=80, scaling ratio 2.5x at 3x chain size (limit 4x)
- pachi/unit/test_pachi_cwe362.c: 8-thread hammer, 100k iterations, zero
double-expansion events with __atomic_store_n fix
katago-0001-findliberties-bitset.patch (UNDF-2026-000000226)
CWE-407: O(N*k) liberty dup scan → O(N) bool seen[] bitset
Peak speedup: 25× on scattered chains
pachi-0001-atomic-is-expanded.patch (UNDF-2026-000001274)
CWE-362: is_expanded flag set before atom fully populated → races
