+# WASM Security Hardening (CSP-friendly)
+
+This document describes the security measures implemented in `@sanctifier/wasm` to ensure it is safe for high-security environments and compatible with strict Content Security Policies (CSP).
+
+## Security Goals
+
+1.  **Zero `eval()` Usage**: The module must not use the `eval()` function, which is a common vector for XSS and is blocked by many CSPs.
+2.  **No `new Function()`**: The module must not use `new Function(...)` (dynamic code generation), which also triggers CSP `unsafe-eval` violations.
+3.  **Strict CSP Compliance**: The module should function perfectly under a CSP header that does not include `'unsafe-eval'`.
+
+## Implementation Details
+
+### Build-time Verification
+
+A dedicated security audit script, `verify-csp-compliance.js`, runs during every CI build. This script performs a byte-level scan of the generated JavaScript glue code to detect any CSP-violating patterns.
+
+**Patterns Monitored:**
+- `eval(...)`
+- `new Function(...)`
+
+### Dependency Hardening
+
+The package uses `wasm-bindgen` (version 0.2.84 or later) configured with `--target web`. Modern versions of `wasm-bindgen` avoid legacy dynamic code generation patterns used for global environment detection.
+
+### Automated CI Verification
+
+The GitHub Actions workflow (`ci.yml`) includes a mandatory "Verify CSP Compliance" step. If any violation is detected in the `pkg/` output, the build fails immediately.
+
+```yaml
+- name: Verify CSP Compliance
+  run: |
+    cd tooling/sanctifier-wasm
+    node scripts/verify-csp-compliance.js
+```
+
+## Testing for Compliance
+
+### E2E Security Tests
+
+We provide an automated E2E test suite using Playwright (`frontend/tests/e2e/csp-security.spec.ts`) that:
+1.  Intercepts browser requests to inject a strict CSP header (`script-src 'self'`).
+2.  Loads the WASM module inside the browser environment.
+3.  Verifies that no CSP violations are logged to the browser console.
+4.  Ensures the module correctly initializes and executes.
+
+### Manual Verification
+
+To run the local audit manually:
+
+```bash
+cd tooling/sanctifier-wasm
+node scripts/verify-csp-compliance.js
+```
+
+## Deployment Recommendations
+
+When deploying the Sanctifier frontend, we recommend the following CSP header:
+
+```http
+Content-Security-Policy: default-src 'self'; script-src 'self'; object-src 'none';
+```
+
+The `@sanctifier/wasm` module is fully compatible with this configuration and does **not** require `unsafe-eval`.
