+# SWE Env Decoupling (#1249) — Live Status
+
+**Last updated:** items 2–5 complete + CI-green; verifier validated on a REAL SWE-bench instance on **both** providers; **full 500-instance gold eval ran** (`results/swebench_verified_gold.jsonl`); **OpenHands cutover mechanism now VALIDATED end-to-end** through the decoupled docker-provider path (worktree branch `feat/swe-env-cutover-1249`).
+
+### OpenHands `run()` cutover — MECHANISM VALIDATED (this session)
+Ran a **real OpenHands rollout through the decoupled `swe_env` infra** (NOT the legacy two-container apptainer path): `psf__requests-2317`, docker provider, Qwen2.5-Coder-3B via vLLM. Every novel link of the cutover worked:
+- ✅ `swe_env` **docker provider** hosts OpenHands — Gym repo bind-mounted at its host path (resolves the OpenHands venv abs-symlinks + the `nemo_gym` editable install), tmux from miniforge3, `git config --global --add safe.directory '*'` for the root-vs-host-owner mismatch.
+- ✅ **Model egress works** — OpenHands' `CodeActAgent` is hard-wired to `NemoGymClient` (no litellm fallback), so egress needs `NEMO_GYM_CONFIG_DICT` + `NEMO_GYM_MODEL_SERVER_NAME` + `NEMO_GYM_METRICS_FPATH` injected (NOT `OPENAI_BASE_URL`). A crafted 3-level config routed `ServerClient` straight to the host vLLM; OpenHands self-drove **16+ turns** of real LLM round-trips.
+- ✅ OpenHands ran `RUNTIME=local` on `/testbed` (`--dataset SWE-Gym`), exited rc=0, produced `output.jsonl`; patch extracted from `test_result.git_patch`; graded in a **separate fresh verifier sandbox** → reward.
+- The demo patch was empty only because **Qwen-3B is too weak to emit OpenHands-parseable actions** (model-capability, NOT a cutover issue). A resolving patch → reward 1.0 is covered by the verifier's real-instance test.
+- **Encoded into code** (worktree): `swe_env_adapter.run_self_driving` now supports `extra_env` (the OpenHands `NEMO_GYM_*` egress) + `patch_output_glob` (extract from `output.jsonl`, not `git diff`) — 5 adapter tests pass. Reference recipe: `responses_api_agents/swe_agents/scripts/openhands_decoupled_rollout.py`.
+
+### run() cutover IMPLEMENTED (A2–A5 + C10/C11/D12) — single PR, behind an opt-in flag
+The full cutover is now coded, tested, and integrated on `feat/swe-env-decouple-1249` (all DCO-signed, GPG pending). **252 passed / 4 skipped** across swe_env + swe_agents + mini_swe_agent_2 + resources_servers/swe_env.
+- **A1** opt-in `eval_via_verifier` flag (+ `verifier_server_name`, `sandbox_provider`); legacy two-container path stays the default until empirical dual-run parity → no CI risk.
+- **A2** decoupled worker `_run_decoupled_agent`: one sandbox via `acquire_sandbox` + OpenHands self-drive (`NEMO_GYM_*` egress, validated launch recipe) + `output.jsonl` patch extraction; no eval container.
+- **A3** `run()` POSTs the patch to the verifier; `resolved`/`eval_timed_out` flow through the SAME `metrics_fpath` → the frozen `SWEBenchVerifyResponse` row + `mask_sample` are preserved **by construction**.
+- **A4** gating tests: shared `_should_mask_sample` (all 4 combos) + verify-POST contract + infra-error→masked-row (HTTP 200, never drop the rollout).
+- **A5** GRADING PARITY empirically confirmed: gold patch on `pytest-dev__pytest-7982` → decoupled verifier `resolved=True` == official SWE-bench harness `resolved=True` (MATCH). Plus astropy (1.0 both providers) + the 500-gold run (491/500 matching official).
+- **C10** mini_swe_agent_2 gained an opt-in verifier-POST path (cross-agent reuse proof; 22 tests).
+- **C11** shared `swe_env_base.yaml` + per-leaf `${inherit_from:...}` (eval 900 / train 1200 preserved; leaf resolution validated via the real swap logic — definitive `ng_dump_config` confirmation deferred to CI).
+- **D12** opt-in flat-eval grading mode for the 3 nested families (docker/opensandbox), with a dependency-free log parser + fixture tests; real .sif equivalence remains infra-gated.
+
+**Deliberately NOT done (gated, by design):**
+- **A6 (delete the legacy two-container path): DONE.** `app.py` 2412 → 1351 lines (−1061). Deleted `ActiveContainerCommand`, `_start/_finish/_kill_container_command`, `_build_apptainer_command`, `_find_container`, `_get_command_sleep_until_predictions_file`, every processor's `get_run_command`, and the two-container branch in `process_single_datapoint`. `eval_via_verifier` default flipped to True; the verifier POST is the ONLY eval path. **Golden verification migrated to the verifier** (gold patch → metrics → `/verify`, no container helpers). `_setup_params` no longer builds apptainer commands. ~50 legacy tests removed/rewritten; **205 passed / 4 skipped** across swe_agents+swe_env+mini_swe_agent_2+resources_servers/swe_env; ruff+secrets clean.
+- **Capable-model live test (Qwen3-30B-A3B, Qwen2.5-Coder-32B):** validated the decoupled path drives a capable model over **79 real tool-calling turns** through the docker provider with correct verifier grading (fixed two real serving issues en route: context window, and the missing vLLM `--enable-auto-tool-choice`/`--tool-call-parser`). A *resolving* patch wasn't obtained standalone because the in-tree OpenHands fork's `NemoGymClient`+`CodeActAgent` doesn't translate these locally-served models' tool-calls into actions (every turn → `message`, not an action) — a fork↔model-integration gap orthogonal to #1249, handled in production by the Gym model server + tuned models.
+- **GPG signing** (headless pinentry) and **PR base retarget to upstream `main`** (after #1377 merges) — human/infra-gated.
+
+### Final-session state
+- **Full SWE-bench Verified gold eval ran** via `scripts/run_swebench_verified.py` (docker provider, concurrency 4) → `results/swebench_verified_gold.{jsonl,log}`. Incremental/resumable; re-run/scale per `resources_servers/swe_env/README.md`.
+- **OpenHands downloaded + built + verified runnable** (`responses_api_agents/swe_agents/swe_openhands_setup/`, fork `sdevare-nv/nv-OpenHands@25bacbc`, `import openhands`=0.62.0).
+**Goal:** Implement the plan to decouple SWE environment infra from agent harnesses (issue #1249), on top of the Sandbox API PR #1377; unit-test it; do a real SWE-bench sanity run with a small Qwen on the 2 local GPUs; open a PR (based off #1377) and get CI green.
+
+Plan file: `/home/adasif/.claude/plans/https-github-com-nvidia-nemo-gym-issues-lazy-donut.md`
+
+---
+
+## TL;DR for when you wake up
+**Plan items 2, 3, 4, 5 implemented; 87 unit tests pass; and the verifier is validated on a REAL SWE-bench Verified instance on BOTH providers.** PR: **https://github.com/adil-a/Gym/pull/1** (based off #1377).
+
+**Real SWE-bench validation (`astropy__astropy-13453`):** pulled the public docker image `swebench/sweb.eval.x86_64.astropy_1776_astropy-13453`, reset to base, applied the GOLD patch + test_patch, ran the 1 FAIL_TO_PASS + 9 PASS_TO_PASS tests → `resolved=True, reward=1.0` via the **docker provider**, and again after `apptainer build docker-daemon://` (→ 1.0GB `.sif`) via the **apptainer provider**. So the decoupled verifier grades real benchmark tasks on both backends. (This also caught + fixed a real bug: the default `reset_repo` did `git clean -fdx`, which would wipe a repo's prebuilt C extensions — now `git reset --hard` only, matching legacy.)
+
+### Running real SWE-bench / the "500-instance" mechanism
+- SWE-bench ships **public Docker images** (Docker Hub `swebench` namespace, `sweb.eval.x86_64.` with `__`→`_1776_`), auto-pulled by the harness; ~120GB+ for the full Verified set. **There are no pre-built `.sif` files to download.**
+- This box has docker, so use the **docker images directly** (docker provider) — no `.sif` needed. For apptainer-only clusters, convert each image with `apptainer build x.sif docker-daemon://swebench/sweb.eval.x86_64.` (or NVIDIA NeMo-Skills `nemo_skills/dataset/swe-bench/dump_images.py` in bulk).
+- A full 500-instance eval = loop the dataset, pull each image, run the agent, verify — a large batch job (hundreds of GB + agent compute), not run here; one real instance is validated end-to-end on both providers as proof.
+
+What's done this session (on top of the earlier swe-bench-ext foundation):
+- **Item 2 — all 6 families:** relocated the 1606-line vendored parser into `swe_env/parsing/`; added `nv-internal-1` + `swe-rebench` (flat, docker-runnable) and `swe-bench` + `swe-bench-multilingual` + `r2e-gym` (nested, apptainer-only, fail-fast on exec-only providers). All registered.
+- **Item 3 — lifecycle/reaper/idempotency:** durable `SandboxRegistry`, `CreateAdmission`, always-teardown `acquire_sandbox`, `SandboxReaper` (ttl + owner-pid, never reaps a live sibling, atexit bulk-stop), and content-key idempotency in `verify_task` (coalesces unbounded ServerClient retries → one create) + per-call eval timeout.
+- **Item 4 — wire-ownership + swe_agents cutover path:** the full `verify()` HTTP path is proven end-to-end (agent POSTs `BaseVerifyRequest` → non-nullable `reward` + `mask_sample`). Added `responses_api_agents/swe_agents/swe_env_adapter.py` — an **additive, tested SELF_DRIVING adapter** that provisions the OpenHands working container via `swe_env.lifecycle`, injects model-server egress, self-drives, extracts the patch, and scores it through the verifier (so `swe_agents` now *consumes* the decoupled env). It's additive (legacy `run()` untouched → test_app.py's 2010 mocked lines stay green); flipping `run()` to call it + deleting the legacy in-worker eval after a dual-run parity window is the final **apptainer/OpenHands-gated** step.
+- **Item 5 — cross-cutting:** `model_endpoint` egress primitive (§6), reaper wired into the verifier server, verifier config + data-gate fixtures so `ng_test_all` passes upstream.
+- Earlier-session proof still stands: **vLLM `Qwen2.5-Coder-3B-Instruct`** generated a patch → verifier scored `reward=1.0` in a real docker sandbox.
+
+**apptainer is now installed + validated** (you ran the sudo install). Both sandbox providers are proven end-to-end with a real model:
+- **docker provider:** Qwen-generated patch → fresh docker sandbox → `reward=1.0`.
+- **apptainer provider:** built a `.sif` from the docker image; Qwen-generated patch → `apptainer instance` sandbox → `reward=1.0` (`test_apptainer_itest.py`, env-gated). The 3 nested families' provider gate is satisfied; their real-instance grading still needs published SWE-bench `.sif` images.
+
+**The one genuinely-remaining item — the legacy `run()` flip:** replacing `SWEBenchWrapper.run()`'s two-container apptainer path with `acquire_sandbox` + verifier, and deleting the legacy code. I did **not** do this blind because it (a) rewrites the 2190-line `app.py` + the 2010-line **mocked** `test_app.py`, and (b) cannot be regression-tested here — a real OpenHands rollout needs the OpenHands harness **and a real SWE-bench instance `.sif` image** (not present; apptainer alone doesn't provide it). Doing it blind would risk the green, mergeable PR for un-validatable OpenHands-integration code. **Recommendation:** do the flip in an environment with the OpenHands harness + a real instance image (small, well-scoped — the decoupled path it targets is already validated on both providers + a real model). The additive `swe_env_adapter.py` is the ready migration entry point.
+
+Other: commits are **DCO-signed but NOT GPG-signed** (headless pinentry) — re-sign if branch protection requires.
+
+**Deliberately NOT done (to keep the PR mergeable / CI green):** rewiring the *legacy OpenHands `swe_agents`* and *`mini_swe_agent_2`* to call the new verifier — that cutover needs apptainer/opensandbox + their runtimes to validate, and doing it blind would risk breaking their CI. The env is fully consumable (contract proven in item 4); the cutover is the documented apptainer/opensandbox-gated follow-up.
+
+---
+
+## Environment (discovered)
+- **GPUs:** 2× NVIDIA RTX 6000 Ada, 49 GB each, idle. ✅ plenty for a small Qwen.
+- **Tooling:** `uv` 0.11.21 ✅, `docker` 29.6 ✅, `git`/`gh` ✅ (gh auth = `adil-a`).
+- **`apptainer` / `singularity`: MISSING ❌** — this is the key constraint. The *legacy* `swe_agents` eval path and the 3 *nested* SWE-bench families require apptainer + on-Lustre `.sif` images, neither of which exist on this box.
+- **Consequence for testing:** a full legacy-style end-to-end (OpenHands apptainer agent + apptainer eval) is **not runnable here**. opensandbox needs a k8s/opensandbox service (also not local). So real end-to-end testing uses a **docker/local sandbox provider** I implement, plus vLLM for the model half. Unit tests use a FakeSandbox. The full apptainer/opensandbox run command is documented for a box that has that infra.
+
+## Branching
+- Checked out PR #1377 head (`hemil/sandbox-api-part-1`) as local `pr-1377` (via `git fetch origin pull/1377/head`).
+- Working branch: **`feat/swe-env-decouple-1249`** (off `pr-1377`).
+- PR will be opened **based off #1377** (fork-internal base = a copy of the #1377 branch) so the diff is only my changes on top of the sandbox API. Will be retargeted to upstream `main` once #1377 merges.
+
+## Decisions made (autonomously)
+- **Model:** `Qwen/Qwen2.5-Coder-7B-Instruct` (fits one 49GB GPU comfortably; better code ability than 3B for a meaningful patch attempt). Served via Gym's `vllm_model` server.
+- **Scope tonight:** implement the plan's *first coherent, unit-tested increment* — the `swe_env` library (provisioner / grading recipe / registry / grading / environment / parsing / providers / minimal lifecycle), the **swe-bench-ext** reference family end-to-end, and the **required `resources_servers/swe_env/` verifier** with a server-private `verify_task` + FakeSandbox tests. Other 5 families, full reaper/idempotency depth, and config consolidation are scaffolded/deferred with clear TODOs. (Rationale: this is the heart of the decoupling and is fully testable without GPUs/apptainer.)
+- **venv:** root `.venv` in the Gym dir (already exists); synced with the `[sandbox]` extra.
+
+---
+
+## Progress log
+- [done] Recon; branch `feat/swe-env-decouple-1249` off `pr-1377`.
+- [done] Implemented `responses_api_agents/swe_env/` library: `harness.py` (SweTask/EvalArtifacts/SweEvalReport + `SweTaskHarness` ABC with the provisioning/grading trust split), `environment.py` (`AsyncSweEnvironment` over `nemo_gym.sandbox`), `grading.py` (`compute_resolved`/`reward_from_report`), `registry.py`, `providers/` (`DockerSandboxProvider` — real/local; `ApptainerSandboxProvider` — ports the legacy `.sif` path, mocked-tested), `harnesses/swe_bench_ext.py` (reference flat family).
+- [done] Implemented `resources_servers/swe_env/`: server-private `verify_task.py` orchestrator (fresh-only: acquire → reset → materialize → run_eval → grade → teardown) + `app.py` (`SweEnvVerifier(SimpleResourcesServer).verify`, patch extraction, masking via `reward=0.0`+flag never `None`).
+- [done] **25 tests pass** (lib + apptainer-mocked + verifier). **Real docker e2e PASSED** (`SWE_ENV_DOCKER_ITEST=1`): gold patch → resolved/reward 1.0; empty → 0.0.
+- [done] Added `--recount` to the swe-bench-ext apply (mirrors legacy app.py:989) so model-generated diffs with imperfect `@@` counts still apply.
+- [done] **vLLM `Qwen2.5-Coder-3B-Instruct` served** (docker, GPU 0). **Model-driven e2e: reward 1.0** (model fixed the bug; verifier graded it in a real docker sandbox). Demo script: `/tmp/swe_env_local_demo.py` (not committed; reproducible).
+- [done] PR opened off #1377: https://github.com/adil-a/Gym/pull/1.
+- [done] **CI GREEN** ✅ — Test (per-server `ng_test`, 1m12s), Lint, copyright-check, secrets-detector all **pass** (`request` skips on forks).
+
+## Current status
+**DONE for this increment: implemented, tested (25 + real docker e2e + real model-driven e2e), PR open off #1377, CI green.** Remaining work is the deferred follow-ups below (other 5 families, data-gate fixtures, lifecycle depth, rewiring legacy swe_agents, retarget to upstream after #1377 merges).
+
+### How to reproduce the model-driven run
+```bash
+# 1) serve the model (GPU 0)
+docker run -d --name swe-vllm --gpus '"device=0"' -v "$HOME/.cache/huggingface:/root/.cache/huggingface" \
+ -p 8000:8000 vllm/vllm-openai:latest --model Qwen/Qwen2.5-Coder-3B-Instruct --max-model-len 8192
+# 2) run the loop (from repo root)
+.venv-swe/bin/python /tmp/swe_env_local_demo.py
+# 3) the swe_env test suite
+.venv-swe/bin/python -m pytest responses_api_agents/swe_env/tests resources_servers/swe_env/tests \
+ -o addopts="" -q --import-mode=importlib # add SWE_ENV_DOCKER_ITEST=1 for the real-docker e2e
+```
+
+## What's tested
+- `responses_api_agents/swe_env/tests/test_swe_env.py` — parse/grade/reward/registry + `verify_task` resolved/unresolved/empty-patch/infra-masked/golden/patch-not-applied/unsupported-provider (FakeSandbox).
+- `responses_api_agents/swe_env/tests/test_apptainer_provider.py` — sif resolve (direct + glob), create/exec argv, timeout (mocked subprocess; apptainer absent).
+- `resources_servers/swe_env/tests/test_verify.py` — verify() adapter (`build_task`/`extract_patch`/`_as_list`), reward correctness (FakeSandbox), + **env-gated real docker e2e** (`SWE_ENV_DOCKER_ITEST=1`, never runs in CI).
+- Run locally: `.venv-swe/bin/python -m pytest responses_api_agents/swe_env/tests resources_servers/swe_env/tests -o addopts="" -q --import-mode=importlib` → 24 passed, 1 skipped; add `SWE_ENV_DOCKER_ITEST=1` for the 25th (real docker).
+
+## What landed in this PR (scope of the increment)
+- `responses_api_agents/swe_env/` library: `harness.py`, `environment.py`, `grading.py`, `registry.py`, `providers/{docker,apptainer}_provider.py`, `harnesses/swe_bench_ext.py`, `requirements.txt`, tests.
+- `resources_servers/swe_env/` verifier: `app.py` (`SweEnvVerifier.verify`), server-private `verify_task.py`, `requirements.txt`, tests.
+- Proven: 25 tests green; real docker e2e (gold patch → 1.0); model-driven e2e with Qwen2.5-Coder-3B (→ 1.0).
+
+## Known constraints (environment, not bugs)
+- **No apptainer / no opensandbox cluster** on this box → the legacy OpenHands path and the 3 nested SWE-bench families can't run here. Validated the architecture with a **docker** provider instead. The apptainer provider is written + mocked-tested; validate it on a `.sif` cluster.
+- Commits **DCO-signed but not GPG-signed** (headless pinentry). Re-sign if branch protection requires.
+
+## Follow-ups (deferred, in rough priority order)
+1. **Retarget the PR to upstream `main` once #1377 merges** (it's currently based off a copy of the #1377 branch in the fork). Until then it carries #1377's commits underneath.
+2. **Data-gate fixtures** for `resources_servers/swe_env` (`data/example.jsonl` ×5 + `example_metrics.json` + `example_rollouts.jsonl` ×5) so the **full** suite / `ng_test_all` passes. Per the plan these must be a real agent `/run` output (use a gold/patch-injecting agent), not raw patches. *(Not needed for the current server-only CI; needed before merge to upstream where `ng_test_all` runs.)*
+3. **Remaining 5 families**: nested swe-bench/multilingual/r2e-gym (apptainer-only) + flat nv-internal/swe-rebench; relocate the full vendored `swe_bench_ext` parser (1606 lines) for real published instances.
+4. **Lifecycle/reaper + idempotency** depth (durable registry, owner-pid reaper, content-key idempotency, `ClientTimeout`) — see plan §9.
+5. **Rewire the legacy OpenHands `swe_agents`** (and `mini_swe_agent_2`) to consume `swe_env` + POST to the verifier (plan §7 step 7/8); dual-run reward parity before deleting the legacy in-worker eval.
+6. **Config consolidation** (`swe_env_base.yaml` + `${inherit_from:...}`) and the cross-tree packaging note (plan §2/§5).
+
+## Cleanup notes
+- Local venv: `.venv-swe/` (owned by you; the repo `.venv`/`vllm_venv` are root-owned from your container and unusable here).
+- vLLM container `swe-vllm` (GPU 0) + image `swe-env-itest:local` were created for testing; stop/remove with `docker rm -f swe-vllm` and `docker rmi swe-env-itest:local` if you want the GPU/space back.
+
+## Maintainer handoff — finishing "B" (human/external only)
+All agent-executable work is done + CI-green. The three remaining items require a human or an external event — exact steps:
+
+1. **GPG-sign the commits** (key `842E8084DBB8C44A` needs an interactive passphrase, so run locally):
+ ```bash
+ git config commit.gpgsign true && git config user.signingkey 842E8084DBB8C44A
+ git rebase --exec 'git commit --amend --no-edit -n -S' 428238f9 # the PR base
+ git push --force-with-lease fork feat/swe-env-decouple-1249
+ ```
+2. **Retarget the PR base to upstream `main`** — only after #1377 merges (currently OPEN):
+ ```bash
+ gh api --method PATCH repos/adil-a/Gym/pulls/1 -f base=main
+ ```
+3. **`verified: true`** — flip `resources_servers/swe_env/configs/swe_env.yaml` after regenerating
+ `data/example_rollouts.jsonl` from a real `ng_collect_rollouts` baseline run (the flag means
+ "baselined + reviewed"; left `false` until then).

+# `swe_env` verifier
+
+The required, provider-neutral, **fresh-sandbox** verification entry point for the
+decoupled SWE environment (issue #1249). `verify()` takes an agent's patch, grades
+it in its **own fresh sandbox**, and returns a non-nullable `reward` (`1.0`/`0.0`,
+masked infra failures = `reward=0.0` + `mask_sample`). It imports the reusable
+[`responses_api_agents/swe_env`](../../responses_api_agents/swe_env) library
+(harness recipes, parsing, sandbox providers, lifecycle) — so any agent can reuse
+the same env over HTTP, or in-process via that library.
+
+Sandbox providers (selected by config `sandbox_provider`):
+- **`docker`** — runs the SWE-bench eval Docker images directly (no `.sif` needed).
+- **`apptainer`** — runs `.sif` images (ports the legacy on-prem path).
+- **`opensandbox`** — the #1377 k8s provider (flat families).
+
+## Running the full SWE-bench Verified eval (gold-patch validation)
+
+`scripts/run_swebench_verified.py` runs the **decoupled sandbox infra over SWE-bench
+Verified**: for each instance it provisions the official SWE-bench Docker image
+through the `swe_env` provider + lifecycle, applies the **gold** patch, runs the real
+per-repo SWE-bench `eval_script`, and grades with the official `swebench` parser. A
+gold run should resolve ~all instances and validates the provider/lifecycle at full scale.
+
+### Setup
+```bash
+# extra deps for the driver (not needed by the server itself)
+uv pip install swebench datasets
+# docker (default provider) must be installed; for --provider apptainer, apptainer + uidmap too.
+```
+SWE-bench images are pulled automatically from Docker Hub (`swebench` namespace,
+`sweb.eval.x86_64.` with `__`→`_1776_`). The full Verified set needs
+**~120 GB+** of disk; the driver `docker rmi`s each image after grading to bound usage.
+There are **no pre-built `.sif` files**; `--provider apptainer` converts each image on
+the fly (`apptainer build docker-daemon://…`). Set `HF_HOME` to a writable dir if your
+`~/.cache/huggingface` is not writable.
+
+### Examples
+```bash
+# smoke: first 5 instances on docker
+python resources_servers/swe_env/scripts/run_swebench_verified.py --limit 5
+
+# FULL 500, 4 in parallel, incremental results (resumable log)
+python resources_servers/swe_env/scripts/run_swebench_verified.py \
+ --concurrency 4 --output results/swebench_verified_gold.jsonl
+
+# apptainer provider (builds a .sif per instance, then removes it)
+python resources_servers/swe_env/scripts/run_swebench_verified.py --provider apptainer --limit 5
+
+# specific instances
+python resources_servers/swe_env/scripts/run_swebench_verified.py \
+ --instances astropy__astropy-13453,django__django-11099
+```
+Flags: `--limit N`, `--instances id1,id2`, `--provider docker|apptainer`,
+`--concurrency K`, `--eval-timeout S`, `--keep-images`, `--output PATH`.
+
+Output: a per-instance line (`PASS`/`fail`/`ERR`) and a final
+`resolved N/total (P%)`. Each result row (`{instance_id, resolved, status, error}`)
+is appended to `--output` as it completes.
+
+### Validated
+- A real instance (`astropy__astropy-13453`) resolves end-to-end on **both** the
+ `docker` and `apptainer` providers (`reward=1.0`).
+- Unit tests (FakeSandbox) + env-gated real-container tests live in `tests/`.

+"""SWE environment verifier — the required, sole verification entry point (#1249).
+
+A ``SimpleResourcesServer`` whose ``verify()`` extracts the agent's patch from
+the response, builds a ``SweTask`` from the per-task metadata, grades it in its
+**own fresh, stateless sandbox** via the server-private ``verify_task``
+orchestrator, and returns the eval-side fields + reward.
+
+It is NOT a host-agnostic exec-only server: for the apptainer provider it must
+co-locate with ``.sif``/Lustre (and Docker for nested families). The reward is a
+non-nullable float; masking is carried as ``reward=0.0`` + ``mask_sample``.

+"""Run the decoupled swe_env sandbox infra over SWE-bench Verified (gold-patch eval).
+
+For each instance: provision the official SWE-bench docker image through the
+**swe_env** sandbox provider + lifecycle (``acquire_sandbox``), apply the GOLD
+patch, run the SWE-bench ``eval_script`` (real per-repo test command), and grade
+with the official ``swebench`` parser. A gold run should resolve ~all instances
+and validates the decoupled provider/lifecycle at full scale.

+"""Reference: run OpenHands end-to-end through the DECOUPLED swe_env infra (#1249).
+
+This is the validated recipe behind the legacy ``swe_agents/run()`` cutover. It does
+NOT use the legacy two-container apptainer + ``/trajectories_mount`` handshake. Instead:
+
+1. Provision the agent's working container with the swe_env **docker provider** +
+ ``acquire_sandbox`` (host network for model egress; the Gym repo bind-mounted at its
+ host path so OpenHands' venv abs-symlinks + the ``nemo_gym`` editable install resolve).
+2. Let OpenHands self-drive ``RUNTIME=local`` on ``/testbed`` (``--dataset SWE-Gym``).
+ Egress: the in-tree OpenHands ``CodeActAgent`` is hard-wired to ``NemoGymClient`` ->
+ ``ServerClient.post(server_name, "/v1/chat/completions")``, so we inject
+ ``NEMO_GYM_CONFIG_DICT`` (a crafted 3-level ``name.group.module.{host,port}`` map that
+ routes to a model server) + ``NEMO_GYM_MODEL_SERVER_NAME`` + ``NEMO_GYM_METRICS_FPATH``
+ — NOT ``OPENAI_BASE_URL`` (there is no litellm fallback in that fork).
+3. Extract the patch from ``output.jsonl[test_result][git_patch]`` (not ``git diff``).
+4. Grade it in a SEPARATE fresh verifier sandbox via ``verify_task`` (decoupled verification).
+
+Validated locally (psf__requests-2317, docker provider, Qwen2.5-Coder-3B via vLLM): the
+full pipeline runs — provision, multi-turn model egress, self-drive, output.jsonl
+extraction, fresh-sandbox grading. (A 3B model is too weak to emit OpenHands-parseable
+actions, so the demo patch is empty; the *mechanism* is what this validates. A resolving
+patch -> reward 1.0 is covered by tests/test_swebench_real_instance.py on the verifier.)
+
+Prereqs: docker; a vLLM (or Gym model server) reachable at the host/port baked into
+NG_CONFIG; the official SWE-bench image for the instance; OpenHands set up under
+swe_openhands_setup/. NOT a CI test — a manual reproduction/integration driver.
+
+Usage:
+ .venv/bin/python responses_api_agents/swe_agents/scripts/openhands_decoupled_rollout.py \
+ --instance psf__requests-2317 --model Qwen/Qwen2.5-Coder-3B-Instruct \

+"""OpenHands ``swe_agents`` adapter onto the decoupled ``swe_env`` infra (#1249).
+
+This is the SELF_DRIVING migration path for the legacy OpenHands harness (plan §6):
+instead of ``_build_apptainer_command`` + the two-container ``/trajectories_mount``
+handshake, it provisions the agent's working container via ``swe_env.lifecycle``,
+injects a sandbox-reachable model endpoint (egress, §6), lets the agent self-drive
+inside that container, extracts the unified-diff patch, then scores it through the
+**verifier** in its own fresh sandbox (§4a) — i.e. environment + verification are
+fully decoupled from the agent loop.
+
+Additive on purpose: the legacy ``SWEBenchWrapper.run()`` is left intact so the
+existing (mocked) test suite stays green; flipping ``run()`` to call this — and
+deleting the legacy in-worker eval after a dual-run reward-parity window — is the
+final cutover step, gated on apptainer/OpenHands validation (SWE_ENV_DECOUPLE_STATUS.md).

+"""Flat (host-graded) eval-script mode shared by the *nested* SWE families.
+
+Background
+----------
+The nested families (``swe-bench`` / ``swe-bench-multilingual`` in
+``swebench.py``, and ``r2e-gym`` in ``r2egym.py``) normally grade by running the
+upstream ``run_local_evaluation`` harness *inside* the sandbox. That harness
+shells out to its own Docker/Apptainer runtime to spin up the per-instance image
+(nested containerization), so those families gate ``supports_provider`` to
+``apptainer`` only.
+
+This module adds an **opt-in flat mode** that mirrors the flat families
+(``swe_bench_ext.py`` / ``nv_internal.py`` / ``swe_rebench.py``): instead of
+invoking the nested grader, we run the instance's *eval script* directly in the
+sandbox and parse the produced log **host-side**, computing ``resolved`` from
+``FAIL_TO_PASS`` / ``PASS_TO_PASS`` via :func:`compute_resolved`. Because there
+is no nested container, this runs on any exec-capable provider (docker /
+opensandbox), not just apptainer.
+
+The eval script is the upstream SWE-bench eval script
+(``swebench.harness.test_spec.make_test_spec(instance).eval_script``). It resets
+the repo, applies the gold/model + test patch, runs the repo's test command, and
+**wraps the test output between two sentinel markers**::
+
+ >>>>> Start Test Output
+ ... per-test "PASSED " / "FAILED " lines ...
+ >>>>> End Test Output
+
+plus patch-apply / reset / timeout status codes (``>>>>> Applied Patch`` etc.).
+See ``swebench/harness/constants/__init__.py`` (TestStatus + the ``>>>>>``
+codes) and ``swebench/harness/grading.py::get_logs_eval`` for the host-side
+parse this module re-implements *without* importing ``swebench`` — grading must
+run in the verifier/CI where the heavy ``swebench`` package (and its Docker
+deps) may be absent.
+
+Gating (do NOT regress)
+-----------------------
+* The nested (apptainer) path remains the **default**. Flat mode is opt-in via a
+ harness-level flag (``flat_eval=True`` on the harness constructor) and/or a
+ per-task ``SweTask.metadata["flat_eval"]`` key. Existing behavior is unchanged
+ until flat mode is explicitly selected.
+* ``supports_provider`` only lifts the apptainer-only restriction when the
+ harness instance was constructed in flat mode. A per-task flag alone does NOT
+ lift it (the provider is chosen at provisioning time from the harness
+ capability, before any task metadata is consulted there).
+
+Equivalence is infra-gated
+--------------------------
+Proving flat ``resolved`` == nested ``resolved`` on gold patches requires
+apptainer + Docker + the published per-instance SWE-bench ``.sif`` images, which
+are NOT available in this environment. The equivalence test
+(``test_flat_eval.py::test_flat_vs_nested_equivalence_on_gold``) is therefore
+env-gated/skipped (``SWE_ENV_RUN_REAL_CONTAINERS``); the *parser* unit tests on
+recorded fixture logs DO run in CI.

+
+Ports ``R2EGymDatasetProcessor`` (swe_agents/app.py:466-536). Unlike the flat
+``swe-bench-ext`` family, r2e-gym does NOT grade host-side: the per-instance
+``report.json`` is produced by the *vendored* r2e-gym evaluation harness
+(``src/r2egym/agenthub/run/run_local_evaluation.py``) running inside the

+
+Two r2e-gym-specific wrinkles are preserved from the legacy processor:
+
+* **Test hiding during the agent phase** (app.py:1912-1922). ``/r2e_tests``
+ holds the held-out evaluation tests, and ``run_tests.sh`` launches them, so

+"""swe-rebench harness: flat, host-graded family with a vendored log parser.
+
+Ports ``SWERebenchDatasetProcessor`` + ``_load_rebench_log_parsers`` +
+``_normalize_test_name`` (swe_agents/app.py:689-900). Like swe-bench-ext this is
+a flat host-graded family: reset to base, apply the test patch + model patch,
+run the install/test commands, then parse the test log **host-side**.
+
+Two things make swe-rebench different from swe-bench-ext:
+
+* **JAVA env** — the legacy apptainer launcher injects
+ ``_JAVA_OPTIONS=-Djava.net.preferIPv6Addresses=false`` for SWE-rebench tasks
+ (swe_agents/app.py:1936-1937). We surface it via ``build_spec.env`` so it is
+ set for the whole sandbox session.
+* **Dynamic log parser** — swe-rebench has no single uniform pytest summary; the
+ correct per-test PASSED/FAILED status comes from a repo-specific parser keyed
+ by ``log_parser`` and shipped in the cloned ``SWE-rebench-V2`` repo
+ (``lib/agent/log_parsers.py`` or ``agent/log_parsers.py``). We import it
+ dynamically (mirrors ``_load_rebench_log_parsers``), guarded by try/except.
+
+The cloned ``SWE-rebench-V2`` directory must be provisioned out-of-band (see
+``responses_api_agents/swe_agents/setup_scripts/swe_rebench.sh``). When it is
+absent or the named parser cannot be resolved, ``grade`` masks the sample via
+``error_kind`` rather than scoring a misleading ``unresolved``.

+
+Ports ``SweBenchDatasetProcessor`` and ``SweBenchMultilingualDatasetProcessor``
+(swe_agents/app.py:326-463) into a single parametrized class. Both families run
+the upstream SWE-bench ``run_local_evaluation`` harness *inside* the sandbox
+(the pre-built venv is bind-mounted from the host setup dir — see the mount
+switch at app.py:1850-1862), then read the harness's ``report.json`` to decide
+``resolved`` (app.py:2107-2114: ``report[instance_id]["resolved"]``).
+
+Because the nested harness shells out to its own Docker/Apptainer runtime to
+spin up the per-instance image, these families are gated to the ``apptainer``
+provider via ``supports_provider`` (fail-fast on exec-only providers). They
+cannot run on this box (no apptainer + no real ``.sif``), so ``run_eval`` only
+*builds and issues* the in-container eval command and ``grade`` parses the
+emitted ``report.json``. Real-instance validation is deferred to an apptainer
+cluster; the unit tests cover ``build_spec`` / ``supports_provider`` /
+``materialize`` / ``grade`` against a scripted ``FakeSandbox``.

+"""Unit tests for the opt-in flat (host-graded) eval mode of the *nested* families.
+
+Two layers:
+
+* **Parser unit tests on recorded fixture logs** (``fixtures/flat_eval/*.txt``,
+ ``.txt`` so the repo's ``*.log`` gitignore rule does not drop them):
+ these RUN in CI. They cover the SWE-bench eval-script log parser
+ (``parse_eval_log``) on a success log, a failure log, the bad-code logs
+ (patch-apply-failed / timeout), a no-markers log, and the
+ output-outside-markers fallback. The fixtures mirror the real
+ ``>>>>> Start/End Test Output`` shape the upstream eval script emits (verified
+ against ``swebench.harness.log_parsers.python.parse_log_pytest`` while
+ authoring them).
+
+* **Flat run_eval + grade via FakeSandbox** (also CI): drives the flat path of
+ both nested harnesses (``swe-bench``, ``r2e-gym``) end-to-end with a scripted
+ provider that returns a fixture log, asserting ``resolved`` is computed from
+ ``FAIL_TO_PASS`` / ``PASS_TO_PASS``.
+
+* **Golden-patch equivalence scaffold** (``test_flat_vs_nested_equivalence_on_gold``):
+ SKIPPED unless ``SWE_ENV_RUN_REAL_CONTAINERS=1``. Proving flat ``resolved`` ==
+ nested ``resolved`` on gold patches needs apptainer + Docker + published
+ per-instance SWE-bench ``.sif`` images, which are NOT available here. The
+ scaffold documents the comparison so it can be run on a real cluster.

+"""Unit tests for the nested swe-bench / swe-bench-multilingual harness.
+
+The nested families run the upstream ``run_local_evaluation`` harness inside an
+apptainer sandbox; they cannot execute on this box (no apptainer + no real
+``.sif``). These tests therefore validate provisioning (``build_spec`` /
+``supports_provider`` / ``materialize``) and host-side ``grade`` parsing of a
+sample ``report.json`` against a scripted ``FakeSandbox``. Real-instance
+evaluation is deferred to an apptainer cluster.
