Gate 2: The Hot-Spot Key Pressure Test (100.0% Collision on Slot 0) Under 100% contention targeting a single 128-byte cache line across 16 concurrent threads and 320,000 operations: ```bash ./bin/hotspot_test ``` ```text ================================================================== MTPO HOT-SPOT KEY LATENCY & CACHE-LINE CONTENTION PRESSURE TEST ================================================================== Contention Target: 100.0% Access to Slot 0 (Single 128B Cache Line) Concurrent Threads: 16 | Total Operations: 320,000 ------------------------------------------------------------------ [1/3] Sorting 320,000 Dual-Timer Latency Samples...

In dedicated real-time pinned environments (`PREEMPT_RT`), this artifact collapses to zero. --- ## 4.

Gate 5: Independent Bare-Metal POSIX Shared Memory (SHM) & Merkle DAG Run To definitively verify execution beyond in-process heap threads, Lean 4 abstract models, and browser WASM sandboxes, we executed the native POSIX shared memory benchmark: ```bash ./bin/shm_dag_test ``` ```text ==================================================================== MTPO: LOCAL POSIX SHARED MEMORY (SHM) & MERKLE DAG RUNTIME TEST Hardware: Physical Apple Silicon M4 (128B Aligned Cache Lines) ==================================================================== [1/5] Initialized POSIX SHM Memory-Mapped Region: Shared Memory Object: /mtpo_posix_shm_dag_benchmark Total Mapped Buffer: 9.20 MB (9,649,664 bytes) Base Memory Address: 0x10906c000 (128B Cache Aligned: YES) [2/5] Spawning 16 Concurrent Worker Threads into POSIX SHM Lattice...
