From dfab48678d9d08cad9e53b1761adb0dad5b0dbda Mon Sep 17 00:00:00 2001 From: Mike Alhayek Date: Thu, 16 Jul 2026 11:07:11 -0700 Subject: [PATCH 1/2] Add per-profile anti-spam throttle overrides for AI Profiles Reshape PromptSecurityProfileSettings to anti-spam throttle-only (max messages/window, message window, max anonymous sessions/window, anonymous session window). Each unset value falls back to the site-wide PromptSecurityOptions default so AI Profiles and templates can raise or lower quotas per use case. High-level input/output security guards remain global-only. - Honor per-profile overrides in DefaultChatRateLimiter (already) and DefaultChatSessionStartRateLimiter (now); keep guards global in DefaultPromptSecurityService and SecurityPromptOrchestrationHandler. - Expose the 4 override fields on the Blazor and MVC AI Profile and Template create/edit forms. - Add unit coverage for override (raise/lower), disable, and partial fallback (one field overridden, the other inherited from the site). - Update prompt-security and ai-profiles docs plus the changelog.

Applied consistently across both the Blazor.Web and Mvc.Web hosts, matching the existing Bootstrap tooltip convention (bi-question-circle + data-bs-toggle). Also wire up the Bootstrap tooltip initializer on the MVC admin settings page.
