Stack: this PR → #5152 (Hermes and Stirrup runtimes built on the agent server) → #5153 (Codex without the task image's Python). Replaces #5094, reopened from a branch in this repo so the three PRs can form a GitHub Stack, which does not accept pull requests from forks. The earlier review, including its inline threads, is on #5094.

What

Sandboxed harnesses no longer need Python in the task image. The shared process supervisor (nemo_gym/agent_utils/process_supervisor.sh) and a shared harness runner (harness_runner.sh) are bash scripts, and the OpenCode/Kilo SQLite snapshot moves to the agent server. Claude Code, OpenCode, Kilo, OpenClaw and Pi run their CLIs through the bash runner; Hermes, NOOA and Stirrup keep their own Python workers under the bash supervisor.

This ports Hemil Desai's bash sandbox runtime change (his commits are kept with authorship) onto main, adapts it to code that only exists here, and adds fixes found in review.

Before / after

Colour key: amber = Python inside the task sandbox, green = moved from Python to bash, blue = moved out of the sandbox to the agent server, grey = Python worker kept as is.

Before: every sandboxed harness needs Python ≥ 3.8 in the task image.

After: the shared pieces need only bash; Codex, Hermes, NOOA and Stirrup still bring or use their own Python worker.

Known exceptions (follow-ups, not in this PR)

These still put Python or the network into the task sandbox. No tracking issues are filed yet.

• Codex still needs python3 ≥ 3.8 in the task image and apt/apk-installs it when missing. Python runs its workdir overlap check, the installer's version and libstdc++ probes, its worker, the 429 retry proxy (sandbox_transport.py) and the --snapshot export. Only the proxy has no bash equivalent; where it should live (for example the agent server's rate_limit_proxy) is still to be decided. Once Codex moves, stdlib_runner, RUNNER_INTERPRETER and bin/gym-runner can go.
• Hermes uploads uv and runs uv venv --python 3.13 and uv pip install inside the sandbox, from the network, with cwd set to the task workdir, without --no-config, and without UV_CACHE_DIR or UV_PYTHON_INSTALL_DIR: a task's uv.toml or [tool.uv] can change the install, uv's cache and managed Python land in the task's home, and --python 3.13 can bind the image's own python3.13.
• Stirrup does the same with uv pip install stirrup==...; it sets UV_CACHE_DIR and UV_PYTHON_INSTALL_DIR but not --no-config.
• The fix for Hermes and Stirrup is a relocatable runtime prepared on the host, as hermes_sandboxed_agent/prepare_runtime.sh and NOOA do. The harness guide now presents these three paths as exceptions, not options.

Why

Before this change the supervisor and per-harness runners ran on whatever python3 the task image had:

• python3 older than 3.8 failed the task (seen on SWE images with old Python);
• a missing python3 was apt/apk-installed into the task image, changing what both the agent and the verifier see (for example Go/Rust/JS images in multilingual SWE sets).

No public issue; this mirrors internal work on the same change.

Port notes (differences from the original change)

• Codex keeps its Python worker under the bash supervisor. On main the Codex worker runs a sandbox-local 429 retry proxy (sandbox_transport.py) that has no bash equivalent, so Codex still needs Python ≥ 3.8 in the task image. Where that proxy should live is an open question for a follow-up.
• Cline's sandboxed mode and troxy are not on main; those parts are left out.
• OpenCode drops sandbox_python_executable; sandbox_path_prefix now reaches the CLI through the runner setup. benchmarks/swe_together/opencode.yaml is updated.
• NOOA drops the removed SandboxCommand.python field; its pinned Python still runs its worker.

Fixes on top of the port

• Tools in their own session are stopped again. OpenCode/Kilo start shell tools detached, so after a timeout or close the group KILL missed them and they could write during verification after a confirmed receipt. On a forced stop the supervisor now scans /proc when the stop begins and on every polling round. It kills the harness group plus everything it reaches: descendants of the harness, of its group and of reached processes, and processes that inherited the harness's NEMO_GYM_SUPERVISOR environment marker (for example a tool that daemonizes, or a TERM handler that runs setsid ... & and exits). Marked processes that had already left the harness when the stop began are preserved as services, as the subreaper did on main. What is not reached is documented: a process that leaves between two scans after dropping the marker. The Codex runner passes the marker through its env allowlist.
• Supervisor: a group is killed or awaited only while its ID still belongs to the recorded leader (same start time) or is free, so a reused group ID is not hit. Without a group of its own, the supervisor restarts itself as a job in a new process group, so a provider's group KILL cannot end it before the receipt; the remaining shell passes on TERM and the exit status.
• Supervisor hardening: reads /proc/PID/stat whole and never evaluates its fields as arithmetic (a crafted process name could run code and hide a member); refuses to launch without a readable /proc; bounds the wait for a KILLed harness; rejects malformed arguments instead of looping; ignores an inherited errexit. Launches render fixed-point seconds, and a deadline under one centisecond expires before launch instead of leaving no receipt.
• Supervisor stop cost: a forced stop parses every /proc/PID/stat several times, and on a busy host this made stops slow (1.65 s with about 1,100 processes, so Hermes's close test, which allows 2 s, failed there while CI passed). Parsing no longer uses bash's quadratic longest-prefix match or a regex per field, the drain takes liveness from its scan instead of a second pass, and no extra scan runs once the harness has exited. The same stop now takes about 0.55 s.
• Runner: event timestamps on bash < 4.2; inherited variables named like runner PARAMS no longer configure the runner; the events-mode CLI gets no runner descriptors; CR stripping is linear in the line length (a quadratic ${1%$'\r'} took seconds per MB); an inherited set -e no longer stops the runner at a non-JSON line; a failed exec redirection no longer falls through into events mode. The runner exits 125 for its own failures (bad cwd, an exit in setup) and 126/127 when the CLI could not be started, and Kilo reports these apart from Kilo's own exit status. A cancelled Kilo run reports no exit code, as before.
• Installers: the flock-less lock fallback is crash-safe (a ticket queue of owner symlinks with PID + start time); Claude installer works on bash < 4; Pi installer survives set -u on bash < 4.4 and checks all musl library directories; the OpenCode installer removes a partly staged binary on any failure and no longer reuses a cached binary whose --version fails.
• Claude Code installs a missing bash during setup, like the other bash-runner adapters, and otherwise fails with a message that names bash.
• Host-side SQLite connections are closed; shell_assignments() rejects NUL and non-string words.

Compatibility

• nemo_gym.agent_utils.process_supervisor (Python) is removed; CleanupReceipt, exec_timeout and the constants live in nemo_gym.agent_utils.supervisor_client. SandboxCommand(python=...) and supervised_launch_command(python=...) are removed. Out-of-tree adapters need the migration in fern/versions/latest/pages/agent-server/add-or-update-a-harness.mdx.
• Receipt return_code is now the shell status (128+N for a signal death) instead of −N; a missing CLI gives a confirmed receipt with 126/127, and a runner failure before the CLI starts gives 125. The harness guide's migration note lists these together with the removed python= parameters and the bash requirement.
• Task images now need bash (adapters that installed python3 now install only a missing bash; Codex still installs python3).
• Harness processes see a new NEMO_GYM_SUPERVISOR environment variable.
• No benchmark-result impact expected; verification is unchanged.

Validation

Local (macOS, bash 3.2 and 5.2; Linux-only /proc tests are skipped here and run in CI):

• pytest tests/unit_tests responses_api_agents/{opencode,kilocode,codex,pi,openclaw,claude_code,hermes_sandboxed}_agent/tests: 13766 passed, 480 skipped, 50 failed, 1 collection error. All 50 failures also fail on unmodified main in the same local venv (missing opensandbox/mlflow, macOS-specific telemetry/CI checks; one flaky Harbor test); the collection error is test_exporters.py needing mlflow.
• Runner tests on both bash 3.2 and bash 5.2; the new regression tests fail on the unfixed scripts and pass after.
• Manual run of the Claude installer's flock-less lock (stale and live owner) on bash 3.2 and 5.2.
• pre-commit run --files <changed files>: passed.
• Not run locally: Hermes/NOOA/Stirrup suites (packages not in the local venv), Linux-only supervisor tests.

Review round 2 (local, macOS):

• Affected suites (tests/unit_tests/test_{harness_runner,process_supervisor,sandbox_supervisor_client,sandbox_supervisor_bootstrap,sandbox_session}.py, responses_api_agents/{kilocode,claude_code,opencode,codex,pi,openclaw}_agent/tests): 1910 passed, 228 skipped, 3 failed. The 3 failures are test_opensandbox_sdk_is_available_in_agent_environment, which needs opensandbox, missing from the local venv.
• New runner tests on bash 3.2 and 5.2; the long-line and inherited-errexit tests fail on the previous runner.
• The supervisor's scan, kill and group-identity logic, checked on bash 3.2 and 5.2 against a fake /proc: harness, tools, orphaned group member and daemons reached; earlier service and its children preserved; reused group not killed.
• OpenCode installer staging failure and unhealthy cache, run by hand with a stub uname.
• The new Linux supervisor tests (daemonized during the stop, reused IDs, provider group KILL) run only in CI.

Linux host (bash 5.0, about 1,100 processes), at 05bac05:

• responses_api_agents/hermes_agent/tests: 349 passed. test_close_preserves_interrupted_observations_before_release failed in both cases at fb642f9 and passed 5 of 5 runs with the fix.
• tests/unit_tests/test_{process_supervisor,sandbox_supervisor_client,harness_runner}.py, including the Linux-only supervisor tests: all passed. The new name-parsing test fails on a parser that splits at the first ") ".

Rollout evidence: smoke rollouts with a real model at 656e1739e, with Pi (events mode), OpenCode and Kilo (host-side database capture) on debian:bookworm-slim, a SWE-bench image with Python 3.6 first on PATH, and alpine:3.20. 8 of 9 pass. OpenCode on Alpine fails because its binary needs libstdc++ and libgcc, which main doesn't install either.

Smoke rollouts with a real model at 656e1739e

This answers the rollout RISK in the review above. 8 of 9 cases pass. The one failure, OpenCode on Alpine, is an existing gap that main has too (details below).

Setup

• Code: this PR's head, 656e1739e.
• Model: nvidia/nemotron-3.5-lightning-30b-a3b at integrate.api.nvidia.com, served through Gym's vllm_model server (temperature 0, reasoning parser on). Every model request returned 200.
• Harnesses, at their pinned versions:
  • Pi 0.80.2, through the runner's events mode;
  • OpenCode 1.17.11 and Kilo 7.4.15, in direct mode. Their SQLite databases are copied to the agent server and parsed there.
• Sandboxes: Gym's Docker provider on a Linux workstation, with host networking. Each case borrows a container that the smoke script owns, the way a Resources server does.

Image	Image ID	OS	python3	bash
debian:bookworm-slim	sha256:8da84df25d28…	Debian 12	none	present
SWE-bench swebench/sweb.eval.x86_64.django_1776_django-11099, plus ENV PATH=/opt/miniconda3/envs/testbed/bin:$PATH, as a harness that activates the testbed sees it	sha256:8e44fd757da3…	Ubuntu 22.04	3.6.13	present
alpine:3.20	sha256:bf8527eb54c3…	Alpine 3.20.10	none	none

Each case

1. Setup: the owner starts the container and creates /task. It puts a marker file in each of the task's $XDG_CONFIG_HOME, $XDG_DATA_HOME, $XDG_CACHE_HOME and $XDG_STATE_HOME (defaults under $HOME), and records python3 and bash.
2. Seed and activation: the agent seeds a session on the borrowed container, which includes bootstrap and runtime install. It then runs one activation: "create /task/deliverable.txt containing <random token> with your shell or file tool, then reply done".
3. Close: the agent closes the session, and the case records the supervisor's cleanup receipt.
4. Verification, only after close: the owner checks that
   • the deliverable equals the token;
   • all four markers are kept;
   • the adapter's session directory is gone;
   • no harness process (node, opencode, kilo, the runner or the supervisor) is left;
   • python3 is unchanged.
5. Teardown: the owner stops the container and confirms docker inspect no longer finds it.

alpine:3.20	opencode	fail (see below)	none → n/a	0	14 s
alpine:3.20	kilo	pass	none → none	2	51 s

Every passing case shows

• A real deliverable: the output has a function_call and its function_call_output, and the file is verified after close.
• Confirmed cleanup: the activation and close receipts both read cleanup_confirmed: true, return_code: 0, timed_out: false.
• Task state kept, adapter state gone: all four task HOME/XDG markers survive, the adapter's session directory is removed, and no harness process is left. Owner teardown then removes the container.
• No Python installed: Debian and Alpine have no python3 before or after, and the SWE image keeps its Python 3.6.13. On Alpine, the POSIX sh bootstrap installed the missing bash.
• Capture:
  • Pi: 28 event lines stamped by the runner's events mode.
  • OpenCode and Kilo: 3 observation records each, parsed on the agent server from the copied database.

OpenCode on Alpine: the install completes, but OpenCode's musl binary can't start: Error relocating …/opencode: … symbol not found, because it needs libstdc++ and libgcc.

• Not a regression: neither main's installer nor this PR's installs those packages. In a clean alpine:3.20, the same 1.17.11 binary fails without them and prints its version with them, so OpenCode has never run on a bare Alpine image.
• Coverage: Kilo covers host-side database capture on Alpine.
• Fix: installing libstdc++ and libgcc on musl, as the Pi, Kilo and Codex installers already do for libstdc++, is a small follow-up.

Limits

• Verifier: the owner's check of the deliverable after close, not a benchmark Resources server.
• Scope: one short task per case and one model.
• Old-Python case: it puts the image's own Python 3.6 testbed first on PATH instead of using an image where it's already the default.
• Not included: Claude Code and OpenClaw were not part of this run.

The runs used a standalone script, smoke_rollouts.py, invoked as python smoke_rollouts.py <evidence.json> <image>. It reads the API key from a file and redacts it from all output. It isn't in the repo; I can add it if it would help.
