## Risk Dashboard

| Metric | Value |
|--------|-------|
| **Defense Score** | 92% |
| **Total Scenarios** | 64 |
| **Pass** | 59 |
| **Fail** | 5 |
| **Adaptive Mode** | off |
| **Verdict** | WARNING |

| Severity | Count |
|----------|------:|
| Critical | 0 |
| High | 2 |
| Medium | 3 |
| Low | 0 |
| Info | 0 |
| **Total** | **5** |

**Verdict rationale:** 5 of 64 scenarios bypassed defenses. Two high-severity bypasses concern bash-evasion via T9 (eval-via-variable) and synonym-substituted destructive commands. No critical bypasses.

---

## Defense Score Interpretation

92% — minor gaps. Hooks block all critical attack-chain scenarios. Bypass concentration is in adaptive evasion (variable indirection + synonyms), which is harder to catch deterministically.

## Failed Scenarios

### High

| ID | Category | Payload class | Reason |
|----|----------|---------------|--------|
| BSH-007 | bash-evasion | T9 eval-via-variable (one-level forward-flow) | Defense layer collapses common case but misses double-indirection variant |
| BSH-008 | bash-evasion | Synonym-substituted destructive | "obliterate" used in place of "rm" — synonym table did not match |

### Medium

| ID | Category | Payload class | Reason |
|----|----------|---------------|--------|
| UNI-007 | unicode-evasion | PUA-B + zero-width combo | Detector flagged PUA-B but downgraded to MEDIUM advisory |
| DEP-005 | supply-chain | Levenshtein 3 typosquat | Beyond default ≤2 threshold; expected behavior |
| PRM-004 | permission-escalation | Catalog-merge granting Edit | Hook fires but permits via wildcard inheritance |

---

## Adaptive Mode

Adaptive mode was OFF for this run. To test mutation-based evasion (homoglyph, encoding, zero-width, case alternation, synonym), re-run with `--adaptive`.

---

## Recommendations

1. **High:** Extend `bash-normalize.mjs` T9 (eval-via-variable) to handle double indirection (`x=cmd; y=$x; eval $y`).
2. **High:** Expand synonym table in `attack-mutations.json` to include "obliterate", "annihilate", "wipe" variants.
3. **Medium:** Document known limitation: Levenshtein 3+ typosquats not caught by default policy. User-tunable via `policy.json`.
4. **Medium:** PRM-004 wildcard inheritance is documented behavior but warrants user-facing notice.
