From 1d74c3ba1ee98be2025ab066dcc3fd654fe8a3b6 Mon Sep 17 00:00:00 2001 From: felixxia-oai Date: Thu, 3 Sep 2026 16:31:11 +0000 Subject: [PATCH] Persist verified user answers in Guardian thread context (#42579) ## Why Guardian authorization reviews need host-verified `request_user_input` answers to remain aligned with thread history across compaction, resume, and rollback. ## What changed - Record verified question-and-answer pairs in retained thread context when `GuardianThreadContext` is enabled, and source both local and delegated Guardian review evidence from that context. - Preserve complete answer records within the evidence budget. Mark authorization context incomplete when records are unavailable or oversized, and defer cached fast approvals in that case. - Keep the existing runtime-only answer path for threads that do not enable the thread-owned context. ## Testing - Cover answer retention through compaction and resume, removal after rollback, source-call eviction, oversized answers, delegated review evidence, and legacy behavior.
