From 87628df77ab1a2622d1193ad835df02ced565bf2 Mon Sep 17 00:00:00 2001 From: felixxia-oai Date: Fri, 4 Sep 2026 18:24:29 +0000 Subject: [PATCH] Preserve root authorization context in Guardian reviews (#42832) ## Why Guardian reviews for delegated workers need the current root instructions and verified answers even after the parent context is compacted. Approvals must also become stale when that root authorization changes. ## What changed - Build bounded root review evidence from retained context, preserving source order and answer scope while prioritizing user instructions over optional assistant context. - Recover retained instructions from Guardian history after compaction and mark authorization incomplete when required instructions or answers are unavailable. - Version root authorization in synchronous and reusable review sessions so an allow result is cancelled when its evidence changes. - Strip parent-only Guardian approvals when forking worker history in retained-context mode. ## Testing - Cover retained and legacy context modes, oversized evidence, message limits, parent compaction, and authorization changes during review.
