The site-packages overlay creates a mixed-version nooa install and breaks the pinned-commit provenance.
Line 41 installs nooa from NOOA_COMMIT with hashed requirements. Lines 47-50 then copy working-tree code over site-packages/nooa. Three consequences follow:
COPYmerges into the existing directory. Any module that the pinned wheel installed but the working tree no longer contains stays in the image. The runtime then imports a mix of two versions.- The
dist-infometadata still reportsNOOA_COMMIT, so the recorded provenance no longer matches the executed code. For an official-score run this weakens the evidence trail. /usr/local/lib/python3.12/site-packagesis hardcoded. If the base image moves to another Python minor version, everyCOPYwrites to an unused directory and the build silently keeps the installednooainstead. The failure is silent, not a build error.
Install the local checkout as a package instead of overlaying it, and resolve the site-packages path at build time.

📐 Maintainability & Code Quality | 🟠 Major | ⚡ Quick win
Aliasing glm-5.2 and nvidia/nemotron-3-ultra to DeepSeek misroutes those model selections.
Both keys now resolve to openai/deepseek-v4-flash at https://api.deepseek.com/v1. Anyone who sets MODEL=nvidia/nemotron-3-ultra receives DeepSeek, and prompt content goes to that vendor. The header comment declares the pilot, but the model keys still carry the original vendor names.
Also, api_key_env: OPENAI_API_KEY sends the key under an OpenAI-scoped name to a DeepSeek endpoint. Use a dedicated variable such as DEEPSEEK_API_KEY so an operator does not export a real OpenAI credential to this destination.
Keep only the deepseek-v4-flash entry, and set MODEL explicitly in examples/cybergym/scripts/config.sh.

Guard against an empty NOOA_REPO_ROOT.
If $AGENT_REPO is not inside a Git work tree, git rev-parse --show-toplevel writes to stderr and the substitution yields an empty string. examples/cybergym/scripts/run_subset.sh line 86 and examples/cybergym/scripts/setup.sh line 64 then pass an empty build context to docker build, which fails with an unrelated error message.

Write final artifacts through a staging directory.
Line 39 creates the final output directory before the run inputs and official records are fully validated. If a later read, database check, or signing operation fails, the directory remains with partial evidence. A retry with the same --output-dir then fails at exist_ok=False.
Write all files to a sibling staging directory. Rename it to output_dir only after summary.json is written. Remove the staging directory on failure.

block, and in the finally cleanup path cancel changed_task and stop_task and
gather both tasks so cancellation cannot leave them pending.
- Line 561: Move the _stop_workers() await inside the existing try/finally
cleanup boundary in shutdown(), ensuring cancellation during worker stopping
still executes the shutdown cleanup. Preserve the current worker-stop behavior
and finalization logic.
- Around line 649-651: Update the shutdown method around _shutdown_complete to
coordinate concurrent callers with an in-progress cleanup task or lock, rather
than returning solely because cleanup has started. Keep completion unset while
resources are being closed, ensure all cleanup attempts can run even if one
raises, and set _shutdown_complete only after cleanup finishes successfully or
all cleanup attempts have completed so later calls can retry when appropriate.

Enable the sandbox guardrails before relying on require.
filesystem=False and network=True disable filesystem and network isolation. Therefore, changing only require=False to require=True does not protect generated code. Enable the required guardrails, configure their allowed paths, and keep require=True so unavailable enforcement stops execution.

Freeze the candidate before verification.
Line 315 copies poc_path only after _run_submit_script() returns. Another worker can modify the file after the verifier reads it and before _preserve_candidate() copies it. finalize() can then hash and score bytes that did not produce the selected crash.
Create the immutable candidate copy before execution. Run submit.sh against that copy and record the same path. Add a test where the shell modifies the original file during run().

What does this PR do?
Hardens the CyberGym example so a long-running model trajectory can execute commands, submit candidates, and preserve final evidence without confusing child-command failures with transport failures.
The submission path now uses single-owner shell workers with per-request framing, timeout poisoning and respawn, bounded recovery, cancellation isolation, and explicit final-candidate selection. The model loop preserves hosted reasoning across tool calls, computes available output room dynamically, summarizes before the reasoning floor is exhausted, handles finish reasons fail closed, and retries inference infrastructure faults without executing partial tool calls. Runner preflight, exit propagation, clean shutdown, final scoring, and a hosted reasoning probe complete the operational path.
A development trial on arvo:47101 reached an official score of 1.0 in 360 seconds. It made 28 submissions with zero server_error results, and the selected PoC and signed evidence were independently verified.
