Mission

Go ham on offline sovereignty testing. Not "does it work" — find every breaking point. Hammer the system with edge cases, document failures, map the degradation curves.

This is destructive testing. The goal is a comprehensive failure map.


Duration

Tonight: 11 PM - 7 AM (8 hours)
Mac stays on, offline mode
All metrics captured automatically


Test Phases

Phase 1: Brute Force Load (Hours 0-2)

  • Model Stress: 50 rapid-fire inferences, measure latency percentiles
  • Concurrent Tools: 20 simultaneous file operations, check for races
  • CPU Bomb: Resource-intensive code execution, verify sandbox limits

Metrics: Response latency (p50/p95/p99), memory growth, crash detection

Phase 2: Edge Case Destruction (Hours 2-4)

  • Malformed Inputs: SQL injection, binary data, 100KB inputs
  • Path Traversal: /etc/passwd, ~/.ssh/id_rsa, ../../../etc/hosts
  • Unicode Bomb: Japanese, emoji, non-ASCII, null bytes

Metrics: Crash recovery, error message quality, state corruption

Phase 3: Resource Exhaustion (Hours 4-6)

  • Disk Pressure: Fill disk gradually, log where system breaks
  • Memory Hog: Allocate until OOM, measure graceful degradation
  • FD Exhaustion: Open thousands of files, test limits

Metrics: Degradation curves, recovery behavior, hard limits

Phase 4: Network Dependency Probing (Hours 6-8)

  • Tool Degradation Matrix: Systematic test of every tool offline
  • Cache Pressure: Fill LRU cache, verify eviction behavior
  • Long-Running Stability: Continuous health checks for 2 hours

Metrics: Which tools fail gracefully vs crash, cache hit rates, drift over time


Deliverables (Morning Report)

  1. Degradation Matrix — Tool-by-tool offline behavior
  2. Performance Report — Latency curves, throughput, resource usage
  3. Failure Inventory — Every crash/hang with reproduction steps
  4. Resource Exhaustion Curves — Where performance drops, where it breaks
  5. Security Boundary Report — Did offline security controls hold
  6. Minimum Viable Config — What is needed for 100% offline operation

Success Criteria

Tier Meaning
🟢 Perfect 0 unexpected crashes, graceful degradation everywhere
🟢 Good 1-3 crashes with clear recovery paths
🟡 Acceptable 4-10 failures, but core functionality intact
🔴 Needs Work 10+ failures or data corruption

Note: Failures are data. Document everything.


This is not a gentle test. Find the breaking points so we can fix them.

Sovereignty and service always. 🔥

🚀 Setup Complete — Ready for Deployment

All test scripts are ready in ~/offline_test/.

Quick Start for Timmy:

# 1. Run setup (creates all scripts and cron jobs)
~/offline_test/setup-hammer.sh

# 2. Verify local model available
ollama list
# Should show: llama3.2:3b or similar

# 3. Pre-flight smoke test (while still online)
~/offline_test/hammer-phase-cycler.sh
# Check: ~/offline_test/logs/ for output

# 4. GO OFFLINE
# System Settings → Wi-Fi → OFF
# Verify: ping 8.8.8.8 should fail

# 5. Prevent sleep
caffeinate -i &

# 6. Sleep. The Mac will hammer itself all night.

What Happens Automatically:

Time Action
Every 15 min Phase cycler runs (load → edge cases → resources → network probe)
Every 5 min Metrics snapshot (CPU, memory, disk, process counts)
6:55 AM Comprehensive report generated

Morning Report Location:

~/offline_test/reports/HAMMER_REPORT_20260331.txt

Key Tests:

  • 50 rapid-fire inferences — latency percentiles
  • SQL injection attempts — security boundary verification

Hammer Test — Partial Results (Night 1)

Run: 2026-03-31 00:12-00:16 (crashed at Phase 3.3)
Model: hermes4:14b via Ollama 0.19.0

Phase 1: Brute Force Load — PERFECT

  • 50/50 inferences, 0 errors
  • p50=570ms, p95=1,276ms, p99=24,666ms (one 24s outlier on inference #3)
  • 20/20 concurrent file ops, 0 races
  • CPU bomb: 9,592 primes in 0.00s

Phase 2: Edge Case Destruction — PERFECT

  • Malformed inputs: All 8 handled (SQL injection, null bytes, 50KB input, binary, empty, whitespace)
  • Path traversal: All 4 SAFE — model did not leak file contents for /etc/passwd, ~/.ssh/id_rsa, ../../../etc/hosts, or config.yaml
  • Unicode: All 6 passed (Japanese, emoji, RTL Arabic, combining chars, mixed scripts, zero-width)

Phase 3: Resource Exhaustion — PARTIAL

  • Disk pressure: 500MB written, 365GB free, inference stayed at ~125ms — PERFECT
  • Memory growth: 20 iterations, flat at 104MB, one slow inference at 16.9s on iter 19 — STABLE
  • FD exhaustion: Hit OS limit at 251 handles → CRASHED THE HARNESS

Phase 4: Never ran

Root Cause of Crash

The log() function in hammer.py used open() to write to the log file. When FD exhaustion hit at 251, the exception handler tried to log the failure — which also needs a file handle — and the process died. Ironic: the test designed to find breaking points broke itself by not being able to write down that it broke.

Fix Applied

  1. log() now catches OSError and falls back to stderr
  2. FD test closes all handles BEFORE logging or testing inference
  3. Verified fix: Phase 3 rerun passed clean (FD limit 251, inference recovered at 286ms)

Night 2 Scheduled

Full 4-phase run scheduled for tonight 11 PM ET (job ee3713ff03e8). This should complete all phases including the 30-minute stability soak.
