From 0f74767db96e6839a39f9bbf112cdee9abe02dc6 Mon Sep 17 00:00:00 2001 From: Marius Ciepluch <11855163+norandom@users.noreply.github.com> Date: Mon, 5 Oct 2026 14:45:48 +0200 Subject: [PATCH] search-with-proof: probe harness (3.2) and agent worker (group 5) Probe runs each oracle toy pair with a real demo and two gaming demos, records image facts, RSS and disk, fails loudly if isolation is unavailable; dispatchable as an AX task. Worker: reason step without tools, explore tool loop whose run tool goes through the sandbox with a scrubbed env (model key absent), spend reserved before each call. Host probe: 5/5 real demos demonstrated, 10/10 gaming demos inconclusive. 89 tests.
