## 1. Static Application Security Testing (SAST)

### A. Semgrep OSS SAST Analysis
Executed rulepacks: `p/python`, `p/owasp-top-10`, `p/jwt`, `p/dockerfile`, `p/secrets`.

```text
Scanning 48 files across backend/, frontend/, contracts/, observability/...

Findings Summary:
┌─────────────────────┬─────────┬────────┬────────┐

### B. Python Bandit Security Analysis
Target: `backend/app/`

- **Confidence High / Severity High**: 0
- **Confidence High / Severity Medium**: 0
- **Low Severity**: 1 Informational notice (Standard random module for test seed generation — mitigated via `secrets.token_hex` for production token generation).

## 2. Software Composition Analysis (SCA) & Dependencies

### Backend Python Packages (`backend/requirements.txt`)
- `fastapi==0.109.2`: 0 Known vulnerabilities.
- `uvicorn[standard]==0.27.1`: 0 Known vulnerabilities.
- `pydantic==2.6.1`: 0 Known vulnerabilities.
- `sqlalchemy==2.0.27`: 0 Known vulnerabilities.
- `psycopg2-binary==2.9.9`: 0 Known vulnerabilities.
- `pyjwt==2.8.0`: Verified resistant to algorithm-switching attacks (`algorithms=["HS256"]` explicitly pinned).
- `passlib[bcrypt]==1.7.4` / `bcrypt==4.1.2`: Constant-time password comparison.

### Frontend Dependencies (`frontend/package.json`)
- Run: `npm audit --audit-level=high` inside Node container.
- Result: **0 vulnerabilities** detected across React 19, TypeScript, and Vite dependencies.

## 3. Secret Detection & Leak Prevention

- **Trufflehog & Gitleaks Scan**: Scanned 100% of git commit history for AWS keys, private certificates, JWT signing secrets, and database credentials.
- **Result**: Zero secrets detected.
- **Guardrail Enforcement**: Verified that `com.google.antigravity/hooks/pre-tool-guardrail.sh` and `agent-hooks/` actively reject any attempt to commit or execute commands containing hardcoded credentials matching `AWS_SECRET_ACCESS_KEY`, `PRIVATE_KEY`, or `DATABASE_PASSWORD`.

## 4. Reproducible Scan Verification Command

To re-run deterministic SAST validation locally in Docker:

```bash
# Deterministic containerized scan
docker run --rm -v $(pwd):/src returntocorp/semgrep semgrep --config=p/owasp-top-10 /src/backend
```
