From 47eed960b380e8c8054eb19985aaefeabc6336c3 Mon Sep 17 00:00:00 2001 From: Dotta Date: Mon, 28 Sep 2026 15:39:29 -0500 Subject: [PATCH] test(runner): add bounded Copilot real-service risk probes Prepare isolated single-turn denial and detached-command oracles with exact native option identities, marker timing, explicit model admission and process cleanup. Credential-free tests do not claim live qualification.
