From 624b45c4dcdc43a64da0307ce59c4508ef2206e9 Mon Sep 17 00:00:00 2001 From: felixxia-oai Date: Thu, 8 Oct 2026 10:32:13 +0000 Subject: [PATCH] Run Guardian conversation classifiers concurrently and preserve action order (#52061) ## Why A conversation classifier waiting for preparation or full response completion can block newer classifications. Concurrent reviews also need to prevent a later action's evidence or low-risk score from being reused for an earlier action. ## What changed - Run conversation classifications independently, forking the latest compatible completed history from an earlier action. Only a valid completion with a newer action index can replace retained history. - Keep admission and observation ordering atomic, and hold capacity permits through full response completion. - Reject cached low-risk scores from later actions for tool-linked approvals, including initial approval checks. - Track originating tool-call IDs separately from approval display IDs, preserving stdin write provenance and excluding synthetic MCP elicitation IDs from tool ordering. ## Testing Add regression coverage for delayed preparation, capacity admission, out-of-order completion, cancellation, invalid retained output, and history snapshots. Exercise pending approval ordering in both `snapshot` and `conversation` modes, and verify linked and unlinked MCP elicitation provenance.
