Single-file SPA playground har nå parser + renderer for alle 18 produces_report=true-kommandoer (Fase 2: 10 høy-prio + Fase 3: 8 gjenstående: mcp-inspect, supply-check, pre-deploy, diff, watch, registry, clean, threat-model). 18 markdown test-fixtures fungerer som kontrakt-anker for parser-utvikling. Komplett demo-prosjekt `dft-komplett-demo` har alle 18 rapporter ferdig parsed inline — klikk-gjennom uten "parser ikke implementert"- paneler. 2 nye archetypes i KEY_STATS_CONFIG: kanban-buckets (clean) og matrix-risk (threat-model). Bug-fix: normalizeVerdictText sjekker nå GO-WITH-CONDITIONS / CONDITIONAL / BETINGET FØR plain GO så betinget verdict (pre-deploy med åpne vilkår) ikke kollapser til ALLOW. Eksponert 11 window-globaler for testing/automasjon (__store, __navigate, __loadDemoState, __PARSERS, __RENDERERS, __CATALOG, __inferVerdict, __inferKeyStats, __renderPageShell, __handlePasteImport, __scheduleRender). 12 Playwright-genererte screenshots i playground/screenshots/v7.5.0/. A11Y-rapport (WCAG 2.1 AA): 0 blokkerende, 3 mindre forbedringer flagget for v7.5.x patch (skip-link, heading-hierarki på project, aria-live toast). Versjonsbump 7.4.0 -> 7.5.0 i 10 filer (package.json, plugin.json, CLAUDE.md header, README badge, CHANGELOG-entry, 3 scanner VERSION- konstanter, ROADMAP, marketplace-rot README). Ingen scanner- eller hook-behavior-changes — purely additive surface. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

|
||
|
||
**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.
