IMMEDIATE ACTION PLAN

What to Do RIGHT NOW on GTX 1050

✅ What We Know Works:

256×256 grid - Compiled and tested
13 guardians - Form with RHO_THRESH=1.00022
Probe sequence - A, B, C, D defined
Power target - 40-60W sustainable on GTX 1050

🚀 STEP 1: Quick Test (5 minutes)

# On GTX 1050 Ubuntu system:
cd ~/fractal_habit  # or wherever you put the files

# Set power limit to 60W (GTX 1050 can handle this)
sudo nvidia-smi -pl 60

# Run a quick test
./probe_256_gtx1050  # or whichever 256 executable you have

Watch for:

Do 13 guardians form? (Should see "NEW GUARDIAN" messages)
Does it run without crashing?
What's the power draw? (run nvidia-smi in another terminal)

🔬 STEP 2: If Step 1 Works (15 minutes)

Run the FULL probe sequence and capture the crash at cycle ~1112:

# Run with output logging
./probe_256_gtx1050 2>&1 | tee probe_run_$(date +%Y%m%d_%H%M%S).log

# Monitor GPU in another terminal:
watch -n 1 nvidia-smi

What to look for:

Cycle 600-649: Probe A (mass injection) - should see "INJ" in probe column
Cycle 800: Probe B (shear rotation) - instantaneous
Cycle 1100-1199: Probe C (VRM silence) - THIS IS WHERE IT CRASHES
Cycle 1400-1499: Probe D (vacuum trap)

📊 STEP 3: Data Collection

If it crashes at ~1112 (as expected), collect:

Error messages from the crash
Last few cycles before crash
GPU status at time of crash (temperature, power, memory)

🛠️ STEP 4: If It Doesn't Crash

If it runs past 1112 without crashing:

Celebrate! The system is more stable than expected
Continue running to see if it crashes later
Monitor for any other issues

⚡ ALTERNATIVE: Quick Power Test

If you want to test power scaling first:

# Test different power limits
for power in 40 50 60 75; do
    echo "Testing at ${power}W..."
    sudo nvidia-smi -pl $power
    timeout 30 ./fractal_habit_256  # Run for 30 seconds
    echo "Power draw: $(nvidia-smi --query-gpu=power.draw --format=csv,noheader,nounits)W"
done

🎯 MINIMUM VIABLE CHECK:

Just answer these questions:

Does it run? (Yes/No)
Do guardians form? (How many?)
What power does it draw? (Watts)
Does it crash? (If yes, at what cycle?)

📋 WHAT YOU SHOULD SEE:

Based on Windows/RTX 4090 testing:

First output: "NEW GUARDIAN" messages (13 of them)
Cycles 0-599: Warmup, guardian formation
Cycles 600-649: "INJ" in probe column (mass injection)
Stable operation until cycle ~1112
Expected crash during VRM silence (omega locked to 1.25)

🆘 IF IT DOESN'T WORK AT ALL:

Check CUDA: nvcc --version (should show CUDA installed)
Check GPU: nvidia-smi (should show GTX 1050)
Check compilation: Recompile with nvcc -O3 -arch=sm_61 -o probe_256 probe_256.cu -lnvml
Check permissions: chmod +x probe_256

🎪 BOTTOM LINE:

Run this command and tell me what happens:

sudo nvidia-smi -pl 60 && ./probe_256_gtx1050

The forensic audit showed the system works. Now we need to see if it works on the actual target hardware (GTX 1050) with actual power constraints (60W).

Report back with:

Does it run?
How many guardians form?
What's the power draw?
Does it crash? If yes, when?

That's all we need to know for the next step.
