RC10 is closed without provisioning or activating Cloudflare Turnstile. The reviewed threat model found no current anonymous browser flow whose residual risk justifies a third-party challenge. The audit instead closed three first-party policy gaps through the existing backend-authoritative, database-backed, fail-closed rate limiter:

- `public_discovery_assist`: `30/300s`;
- `public_support_assist`: `30/300s`;
- `public_search_area_normalize`: `20/300s`.

The exact implementation head passed RC10, backend/container, generated-client, W7/W8/PWA, runtime-audit, recovery, staging, Phase 11 synthetic, RC5–RC9 and documentation gates through runs `30279827057`, `30279827068`, `30279826976`, `30279831964`, `30279826827`, `30279829353`, `30279829473`, `30279826788`, `30279829352`, `30279826525`, `30279826679`, `30279826805`, `30279829444`, `30279829654`, `30279829433`, `30279829956`, `30279829618`, `30279826638`, `30279829561` and `30279827241`.

No site key, secret, widget, package, challenge token, hostname binding or runtime dependency exists. Android and machine-to-machine traffic are unaffected. Real participants, production authentication, external communications, production AI/Maps, payment-provider activation, real money and formal Phase 12 release remain blocked.

The repository write lane is released. RC11 is next but unclaimed.
