DEFECT FOUND: see gearsystem-0001

MOAD-0001 (CWE-407): DEFECT -- gearsystem-0001
  - Processor::CheckBreakpoints() called per Z80 opcode: O(B) linear scan.
  - Processor::CheckMemoryBreakpoints() called per memory Read/Write AND
    per VDP memory access (Video.cpp:532,575,582,608,648): O(B) each.
  - Z80 at ~3.58 MHz + VDP VRAM/CRAM accesses: >5M O(B) scans/second.
  - At B=64: >320M comparisons/second in debug mode.
  - Fix: std::unordered_set<u16> index per type for O(1) lookup.

MOAD-0002 (Intertangle): CLEAN
  - GearsystemCore aggregates subsystems by design (intentional emulator
    architecture). Each subsystem (Processor, Memory, Video, Audio,
    Cartridge) has independent state and a clean interface.

MOAD-0003 (Leaked Context): CLEAN
  - No thread_local or TLS usage. Single-threaded emulation loop.

MOAD-0004 (CWE-312): CLEAN
  - Pure game emulator with no authentication, credentials, or secrets.
    TraceLogger logs CPU opcodes and register state -- no sensitive data.

MOAD-0005 (Thundering Herd): CLEAN
  - Single-threaded, deterministic emulation. No concurrent cache patterns.
