From df9d8a70d5060f3dc309d7a022cb3e98a3241bac Mon Sep 17 00:00:00 2001 From: John Matthew Tennant Date: Thu, 5 Nov 2026 10:55:37 -0500 Subject: [PATCH 1/4] test(security): show security explanations time out at high effort A security alert's explanation runs in a hidden session that inherits the user's default thinking effort. At high or max effort the model can think past the 20 s budget before writing text, and the failure is never logged. These tests expect the session to turn thinking off and the failure reason to reach the app log.
