Arcplume runs Grok through the Grok Build CLI's own OAuth-authenticated session (grok login) for image generation, with strict preflight validation, secret-safe handling, and headless CLI-driven execution -- no separate XAI_API_KEY billing. Video falls back to the billed xAI API. USE WHEN a user wants to generate an image via a locally logged-in Grok Build CLI session, e.g. 'generate an image with grok', 'use grok build', or 'use my logged-in grok session'.
Shared reference for the Selemene cluster: the two report surfaces (deterministic Rust reports vs. narrative witness-pipeline readings), the @selemene/bridge CLI contract, the output manifest format, and non-prescriptive witnessing tone. USE WHEN deciding which Selemene surface to invoke or when routing between birth/compatibility/transit reports and solo/dyadic readings.
Route Selemene Engine tasks to the right surface: deterministic reports (birth/compatibility/transit) via selemene-core and the @selemene/bridge CLI, or narrative witness readings via selemene-report. USE WHEN the user wants anything under the Selemene/Noesis umbrella but has not named the exact surface.

| Check | Description |
|---|---|
DEBUG = False | Never run with DEBUG in production |
| HTTPS only | Force SSL, secure cookies |
| Strong secrets | Use environment variables for SECRET_KEY |
| Password validation | Enable all password validators |
| CSRF protection | Enabled by default, don't disable |
| XSS prevention | Django auto-escapes, don't use |safe with user input |
| SQL injection | Use ORM, never concatenate strings in queries |
| File uploads | Validate file type and size |
| Rate limiting | Throttle API endpoints |
| Security headers | CSP, X-Frame-Options, HSTS |
| Logging | Log security events |
| Updates | Keep Django and dependencies updated |
Remember: Security is a process, not a product. Regularly review and update your security practices.
