    ASSERT_EQ(status, STATUS_NOT_SUPPORTED);
    ASSERT_EQ(ops, NULL);
    
    // Verify event 17301 logged
    ASSERT_EVENT_LOGGED(17301, unsupportedDevices[i]);
}

// Verify driver unloads for this adapter

Pass Criteria:

• NULL pointer detected (runtime or compile-time)
• Event 17302 logged
• System does not crash in production (static assertion prevents this)

ctx.HwOps = &HwOpsI210;
ctx.HwContext = &i210Context;

// Attempt to read beyond BAR0 size
ULONG value;
NTSTATUS status = ctx.HwOps->ReadRegister32(ctx.HwContext, 0xFFFFFFFF, &value);

ASSERT_EQ(status, STATUS_INVALID_PARAMETER);

ASSERT_EQ(status, STATUS_REVISION_MISMATCH);
ASSERT_EVENT_LOGGED(17307, 1, 2);  // Expected v2, got v1

// Verify driver load fails
status = InitializeHardwareContext(&ctx, NULL);
ASSERT_NE(status, STATUS_SUCCESS);

Pass Criteria:

    PFILTER_ADAPTER_CONTEXT ctx = (PFILTER_ADAPTER_CONTEXT)param;
    
    for (int i = 0; i < 10000; i++) {
        LARGE_INTEGER timestamp;
        
        // Acquire lock before hardware access
        NdisAcquireSpinLock(&ctx->RegisterLock);
        
        // Detect concurrent access (should not happen with lock)
        if (InterlockedIncrement(&threadCount) > 1) {
            InterlockedIncrement(&raceDetected);
        }
        
        ctx->HwOps->ReadPhc(ctx->HwContext, &timestamp);
        
        InterlockedDecrement(&threadCount);
        NdisReleaseSpinLock(&ctx->RegisterLock);
    }
    
    return 0;
}, &ctx, 0, NULL);

// Thread 2: Adjust PHC
HANDLE thread2 = CreateThread(NULL, 0, [](LPVOID param) -> DWORD {
    PFILTER_ADAPTER_CONTEXT ctx = (PFILTER_ADAPTER_CONTEXT)param;
    
    for (int i = 0; i < 10000; i++) {
        NdisAcquireSpinLock(&ctx->RegisterLock);
        
        if (InterlockedIncrement(&threadCount) > 1) {
            InterlockedIncrement(&raceDetected);
        }
        
        ctx->HwOps->AdjustPhcFrequency(ctx->HwContext, 100);
        
        InterlockedDecrement(&threadCount);
        NdisReleaseSpinLock(&ctx->RegisterLock);
    }
    
    return 0;
}, &ctx, 0, NULL);

WaitForMultipleObjects(2, (HANDLE[]){thread1, thread2}, TRUE, INFINITE);

TC-ERR-008: Device-Specific State Overflow (ES-PORT-HAL-009)

Error Scenario: HW_CONTEXT.DeviceSpecific union too small for new hardware
Expected: Compile-time assertion failure

Test Steps:

// Static assertion in production code:
// C_ASSERT(sizeof(HW_CONTEXT.DeviceSpecific) >= sizeof(I210_CONTEXT));
// C_ASSERT(sizeof(HW_CONTEXT.DeviceSpecific) >= sizeof(I225_CONTEXT));
// C_ASSERT(sizeof(HW_CONTEXT.DeviceSpecific) >= sizeof(I226_CONTEXT));

// Runtime test: Verify union size
ASSERT_GE(sizeof(((HW_CONTEXT*)0)->DeviceSpecific), sizeof(I210_CONTEXT));
ASSERT_GE(sizeof(((HW_CONTEXT*)0)->DeviceSpecific), sizeof(I225_CONTEXT));
ASSERT_GE(sizeof(((HW_CONTEXT*)0)->DeviceSpecific), sizeof(I226_CONTEXT));

// Simulate new hardware with larger context
typedef struct {
    UCHAR Buffer[2048];  // Intentionally large
} I227_CONTEXT;

// This should fail at compile time if static assertion exists
// ASSERT_GE(sizeof(((HW_CONTEXT*)0)->DeviceSpecific), sizeof(I227_CONTEXT));

Pass Criteria:

• Static assertions prevent deployment
• Union size checked at compile time
• Build failure prevents introduction of oversized context

    HARDWARE_OPS Base;
    GET_TEMPERATURE_FN GetTemperature;  // New operation
} HARDWARE_OPS_V2;

// i225 implements new operation
NTSTATUS I225_GetTemperature(PVOID Context, PLONG Temperature) {
    *Temperature = 45;  // Mock value
    return STATUS_SUCCESS;
}

// i210 uses default stub (not implemented)
NTSTATUS Default_GetTemperature(PVOID Context, PLONG Temperature) {
    TraceInfo("GetTemperature not implemented for this device");
    EventLog(17310, "GetTemperature");
    return STATUS_NOT_IMPLEMENTED;
}

// Test with i225 (implemented)
LONG temp;
NTSTATUS status = I225_GetTemperature(NULL, &temp);
ASSERT_EQ(status, STATUS_SUCCESS);
ASSERT_EQ(temp, 45);

// Test with i210 (not implemented)
status = Default_GetTemperature(NULL, &temp);
ASSERT_EQ(status, STATUS_NOT_IMPLEMENTED);
