From 24c39d080c9e5f5a431a209606c47ddf68013c92 Mon Sep 17 00:00:00 2001 From: "sentry-junior[bot]" <264270552+sentry-junior[bot]@users.noreply.github.com> Date: Thu, 29 Oct 2026 16:07:09 +0000 Subject: [PATCH 1/2] test(evals): Add evals for provider failure, pushback, stale memory, and injected instructions Add five behavioral cases that measure how Junior uses tool evidence. They give a baseline for the system prompt restructure in #2364. Run behavioral and integration evals when the system prompt or the SOUL.md and WORLD.md loading path changes.
