Subject: [PATCH] fbneo: 1 CWE-407 defect, MOAD 0002-0005 CLEAN; mame: update
 scan to all 5 MOADs CLEAN

fbneo-0001: BurnDrvGetIndex O(N) linear scan over 24493 drivers -> O(1) unordered_map,
91x speedup at N=5000. Fix: hash index built at BurnLibInit, cleared at BurnLibExit.
mame: confirmed CLEAN on all 5 MOADs (binary search for driver lookup, single-threaded).

+# FinalBurn Neo — MOAD 0002-0005 Scan: CLEAN
+
+**Date:** 2026-03-31
+**Scanner:** agent blackops
+**Scope:** src/burn/, src/burner/, src/cpu/tms34010/
+
+## MOAD-0002 (Intertangle): CLEAN (by design)
+
+`nBurnDrvActive` is a global index used both as "active driver cursor" and as a
+temporary scan index. This is a known architectural pattern in FBNeo, not a runtime
+coupling defect -- all driver enumeration uses guard/restore patterns.
+
+## MOAD-0003 (Leaked Context): CLEAN
+
+No `thread_local`, `__thread`, or ThreadLocal constructs found in src/. FBNeo is
+single-threaded (emulation + UI on one thread).
+
+## MOAD-0004 (CWE-312 Logged Secret): CLEAN
+
+No credential, token, session password, or API key logging found. `bprintf` calls
+log emulation state. Netplay (Kaillera) session handling does not log passwords.
+Spectrum game descriptions include in-game passwords as ROM metadata -- not credentials.
+
+## MOAD-0005 (Thundering Herd): CLEAN
+
+Our cx4.cpp program cache (SNES coprocessor) is a 2-slot LRU. FBNeo is
+single-threaded; no concurrent cache races are possible.

+MAME uses a `running_machine` object that owns all subsystems. Device state is
+encapsulated per-device. No shared mutable god-object coupling unrelated subsystems.
+`g_profiler` is a profiling-only singleton with no behavioral coupling.
+
+## MOAD-0003 (Leaked Context): CLEAN
+
+No `thread_local` or `__thread` declarations found in src/emu/ or src/frontend/.
+MAME is architecturally single-threaded (one machine per process).
+
+## MOAD-0004 (CWE-312 Logged Secret): CLEAN
+
+No credential, token, password, or API key logging found. `osd_printf_*` calls
+log game state and configuration only.
+
+## MOAD-0005 (Thundering Herd): CLEAN
+
+Our only significant cache is `driver_enumerator::m_config` (machine_config LRU).
+MAME is single-threaded; no concurrent cache population races are possible.
