From 1e9e8bdb008549fc558ef886791c185c6d3c0814 Mon Sep 17 00:00:00 2001 From: jif Date: Thu, 5 Nov 2026 13:27:11 +0000 Subject: [PATCH] Resample Guardian denials with the original request (#59659) ## What changed When `features.guardian_denial_reconsideration` is enabled, retry the first terminal denial once using the unchanged inference request. Buffer provisional output so only the selected response enters reviewer history, while allowing tool calls to proceed normally. Preserve the original denial if the retry fails or times out, and continue to honor cancellation. Account for token usage from both attempts, including failed reviews. Remove `auto_review.experimental_denial_reconsideration_prompt` and warn when it remains in configuration. ## Testing Update the Guardian scenario and snapshot to verify identical retry inputs, retained tool evidence, and reuse of the selected assessment in a subsequent review, with asynchronous compaction enabled.
