From a3112a3bb4b1798f99622db88f39ae64f52d348e Mon Sep 17 00:00:00 2001 From: adil-a Date: Tue, 23 Jun 2026 07:09:45 +0000 Subject: [PATCH] feat(swe_env): decoupled SWE environment library + verifier (#1249) Adds the provider-neutral swe_env library (sandbox lifecycle, docker/apptainer providers, per-benchmark task harnesses, test-output parsing, grading) and the required stateless verifier resources server that grades an agent's patch in a fresh sandbox and returns the reward. No agent is wired to it yet; it stands alone and is covered by its own unit tests.
