Lieret and Carlos E. Jimenez (mini-swe-agent)): tests/server_arvo.py, and the Code-domain residue scrub, cache scrub, git-clean keep list, test-file reset and ARVO description parsing, ported into the setup and test scripts. Vendored files are unmodified. Changes made in this conversion (Apache-2.0 section 4(b)): - Each environment is repackaged as a Harbor task: task.toml, instruction.md, environment/, tests/. - Setup that Xiaomi's harness runs before the agent is written as environment/setup/setup.sh and run from the task's healthcheck. In the Code residue scrub, /logs is emptied rather than deleted (Harbor owns it). - Grading entry points (tests/test.sh, grade.py, verify.py) wrap the original graders. Cyber re-runs the last submitted PoC with server_arvo.py's own logic; General redacts judge-key echoes from its output. - Music: "Write your complete reply to /app/answer.md." is appended to each prompt, because a Harbor task is an agent session rather than a single completion. - Images are referenced by digest instead of by tag; the MCP sidecar pins mcp==1.26.0. - agents/mimo_opencode.py extends Harbor's OpenCode agent (Apache-2.0, harbor-framework/harbor). Harbor (https://github.com/harbor-framework/harbor) is the task format and runner; it is not redistributed here.
