# 🛡️ Detection Matrix

**Last updated:** 2026-02-15 22:35 UTC

These results come from an **adversarial test suite** — payloads specifically crafted to bypass detection. The 71.6% rate reflects worst-case performance against targeted, research-grade attacks.

## Summary

| Metric | Value |
|--------|-------|
| Total Payloads | 81 |
| ✅ Detected | 58 |
| ❌ Missed | 23 |
| Detection Rate | 71.6% |

## How to Contribute

See a ❌ that you think should be detected? Here's how to help:

1. Check if there's already an issue for that technique
2. If not, open an issue describing the attack vector
3. Or submit a PR improving detection!

## Legend

| Symbol | Meaning |
|--------|---------|
| ✅ | Detected (working as expected) |
| ❌ | Missed (not detected) |
| 🔴 | Regression (was detected, now missed) |
| 🎉 | Improvement (was missed, now detected) |

### Expected Values

- `detected` — Must be detected, CI fails if not (regression protection)
- `missed` — Known limitation, CI passes regardless
- `unknown` — New/unclassified, CI passes, result recorded
