DEFECT FOUND: see gearboy-0001

MOAD-0001 (CWE-407): DEFECT -- gearboy-0001
  - Processor::CheckBreakpoints() called per opcode: O(B) linear scan over
    m_breakpoints vector. B = number of active breakpoints.
  - Processor::CheckMemoryBreakpoints() called per memory Read/Write via
    Memory_inline.h: O(B) linear scan per access.
  - At ~4 MHz with B=64 breakpoints: ~256M comparisons/second in debug mode.
  - Fix: std::unordered_set<u16> index for O(1) point-breakpoint lookup.

MOAD-0002 (Intertangle): CLEAN
  - GearboyCore aggregates subsystems (Processor, Memory, Cartridge, Video,
    Audio) but this is intentional emulator architecture, not god-object
    coupling. Each subsystem has a clean interface and independent state.

MOAD-0003 (Leaked Context): CLEAN
  - No thread_local or TLS usage. Gearboy is single-threaded per emulation
    instance. Audio uses SDL callbacks but carries no request context.

MOAD-0004 (CWE-312): CLEAN
  - No authentication, credentials, or secrets. Pure game emulator.
    TraceLogger logs CPU registers and memory -- no sensitive data.

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