From baab1705c60089f919accc11608aa0df02f634f7 Mon Sep 17 00:00:00 2001 From: felixxia-oai Date: Fri, 14 Aug 2026 18:57:47 +0000 Subject: [PATCH] Make Guardian v2 risk classification configurable (#38628) ## What changed - Allow `features.guardianv2` to remain a boolean toggle or specify classifier instructions, the review threshold, reasoning effort, and action and instruction token limits. - Add transcript controls for included sources, per-entry and total token budgets, and the number of recent non-user entries. - Validate configured ranges and relationships, expose them in the generated config schema, and apply the resolved settings throughout Guardian v2 classification and approval review. ## Testing - Cover boolean compatibility, configuration parsing and boundaries, config-manager rejection, and the resulting classifier request and approval decision.
