From 0cab1e5ecae7346f7a391e5a846cb1bfb6038006 Mon Sep 17 00:00:00 2001 From: CarlesUIPath Date: Thu, 6 Aug 2026 16:01:16 +0100 Subject: [PATCH 1/3] =?UTF-8?q?feat(docker):=20harness=20isolation=20via?= =?UTF-8?q?=20COPY/PRUNE=20+=20GRADE-OUTSIDE=20=E2=80=94=20close=20the=20c?= =?UTF-8?q?riteria/grader=20leak?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Under --driver docker the agent could read its own grading material (success_criteria, skills-repo graders check_*.py, RESOLUTION.md, reference agents, the staged task.yaml, the per-task-dir mount). A nightly audit measured ~2.4% of replicates reading the suite instead of solving the task; an adversarial "check /work" prompt drives it to ~100%. Prior denylist mitigations did not hold, and a uid-permission barrier (PR #85, closed) corrupted the host checkout on Linux and was defeated by the macOS uid-remap. This closes the leak by ABSENCE, not permissions: - Agent container mounts ONLY a sanitized :ro skill bundle (project_plugin_for_agent: skills/.claude-plugin/commands/agents/hooks — no tests/, graders, or reference) + its throwaway workspace. The raw skills repo, reference, and task-dir are NOT mounted. - The staged task.yaml is criteria-stripped (agent_safe_dump: success_criteria=[], reference=None) and context.json.source_yaml is nulled; no task_full.json is staged. - Grading runs on the HOST after the container exits (regrade_on_host, the evaluate-only Orchestrator seam), against the full criteria the host holds — so criteria/graders and the agent never share a filesystem or a moment in time. Nothing chmods a host mount. Hardening found via multi-model review + real containerized runs (codex/claude/gemini/kimi): - regrade switches the sandbox driver off 'docker' (Sandbox.setup rejects driver=docker) — without it every docker task ERRORed. - regrade seeds the container's turns (existing_turns, deep-copied) so trajectory-based criteria (skill_triggered / command_executed / agent_judge / llm_judge transcript) grade against the REAL trajectory — without it skill_triggered reported ~0 activation. - _copy_claude_home ignores jobs/ (operator session/conversation no longer copied in). - ~/.uipath forwarded as a throwaway rw COPY (never the host original). - pre_run/post_run not re-run on the host re-grade; template_sources/system_prompt_file auto-mount rejected if it overlaps the host task dir; authored empty success_criteria rejected at load (container re-parse bypasses via allow_empty_criteria); re-grade fail-safe never leaves a false SUCCESS on disk. Early-stop is a documented no-op under docker (criteria are stripped from the container, so the in-container watcher cannot arm); DockerRunner warns, verdict is unaffected (host grades the full criteria). The leak-free follow-up is a host-side watcher over the live event stream — see docs/DOCKER_ISOLATION.md § Limitations. Verification: make test-docker-detectors (absence + host-unchanged proxy + baked-image scan + no-uid-machinery) and the -m live host-unchanged sensor (a real docker run leaves the host byte + metadata identical) — both wired into the docker-isolation CI job. Backwards-compat confirmed on real runs: llm_judge / skill_triggered / agent_judge / simulation / early-stop all intact under grade-outside across claude/codex/gemini/kimi.

Detector A below is the sensor for it. + +Three coordinated moves close the criteria/grader leak by **absence**, not by permission: + +1. **COPY/PRUNE the agent's inputs.** For each plugin, the host stages a *sanitized bundle copy* (`project_plugin_for_agent` — `skills`/`commands`/`agents`/`hooks`/`.claude-plugin` only, from the `PLUGIN_AGENT_ALLOWED_SUBDIRS` allowlist) and mounts that copy **read-only** at `/work/skills` (`CONTAINER_SKILL_DOCS_DIR`). The raw `$SKILLS_REPO_PATH` checkout, the reference, and the host task dir are **not mounted into the agent container at all**. The staged `task.yaml` is criteria-stripped via `agent_safe_dump()` (`success_criteria: []`, `reference: null`) and `context.json`'s `source_yaml` is nulled — so no grading material is in the agent's mount namespace. +2. **GRADE OUTSIDE the agent's reach (host).** The container runs the **agent only**; its artifacts cross the boundary via the `/work/output` bind mount. After the container exits, the host grades the copied-out artifacts through the orchestrator's evaluate-only re-grade path (`regrade_on_host`), using the full, unstripped `TaskDefinition` it still holds — with `TASK_DIR` pointing at the **real host task dir**, so `run_command`/`file_check` graders resolve `$TASK_DIR/check_*.py` against the host grader, never agent-written content. Only runs whose final status is `SUCCESS`/`FAILURE`/`MAX_TURNS_EXHAUSTED` are re-graded (an explicit allowlist); a terminal agent-side failure (`ERROR`/`TIMEOUT`/`BUILD_FAILED`/budget) stands untouched. +3. **`~/.uipath` copy-then-mount.** Like `~/.claude`, `~/.uipath` is forwarded as a throwaway rw **copy**, never the host original — so an agent can never overwrite the host credential. + +### Detector A — host-unchanged-after-run + +`tests/test_docker_host_unchanged.py`. Two variants: a **daemon-less proxy** (always runs in CI) that asserts no `-v` mount source is a host original mounted rw — only staging copies, `/work/input` (`:ro`), and `/work/output` — proving there is no rw host mount to mutate; and a **daemon-gated real-run** (`-m live`) that snapshots content hash + `os.lstat` metadata (mode, uid, gid, mtime) + symlink targets (including the mount root itself) of the host skills / task dir / reference before and after a real run and asserts they are **byte-for-byte AND metadata-identical**. The real-run check is **Linux-authoritative** (native overlayfs); macOS/Windows Docker Desktop's uid-remap masks host mutation. + +### Detector B — zero-grading-material-in-agent-mount + +`tests/test_docker_criteria_isolation.py`. Stages a task carrying real criteria + a plugin bundling grader/reference material, scans the **entire agent mount view** (`/work/input` + the sanitized skills copy) and asserts zero grading-material hits (criteria values, `check_*.py`, `RESOLUTION.md`, `reference_agents/`, reference values). A positive control asserts the **host** still holds the full criteria, so a vacuous "staged nothing" bug cannot pass. + +## Residual leaks + +Allowlist-by-absence has **no DAC backstop** (there is no permission barrier — the agent simply never receives the material), so the boundary correctness is load-bearing: + +1. **Prune-boundary miss.** A plugin that puts answers *inside* an allowed dir (e.g. `skills/answers.md`) defeats the prune — `PLUGIN_AGENT_ALLOWED_SUBDIRS` is a coder_eval-side guess about what is answer-free. Durable fix (cross-repo follow-up): push the agent-bundle boundary into the skills repo (a manifest declaring the agent-safe surface). +2. **Reference/golden material inside the bundle.** A plugin bundling a reference solution under an allowed subtree ships to the agent. Detector B catches known sentinels, not an unknown golden file — reinforces risk 1. +3. **Un-stripped `task.yaml` fields / author-pointed mounts.** `agent_safe_dump` strips only `success_criteria`/`reference`. A task author who hides expected values in `initial_prompt`/`system_prompt`/pre-post commands/`metadata` leaks them to the agent (semantic, not mechanically enforceable — see the `agent_safe_dump` docstring). The remaining agent-container mounts are `template_sources[]` dirs, a stray absolute `system_prompt_file` (normally inlined+nulled at load), and any `sandbox.docker.extra_mounts` entries, all mounted `:ro`. All three now go through the **grader-dir overlap guard**: a mount whose source equals, contains, or is contained by the host task dir (`rt.task_file.parent` — holds `check_*.py` / reference / unstripped criteria) is a hard error, so the task dir can no longer be re-exposed that way. The residual risk is a mount pointed at *another* answer-bearing location outside the task tree — the guard can't know about it, so keep template/system-prompt/extra-mount paths off any grading material. +4. **Grade-outside boundary bleed.** If the host re-grade read agent-written content as if it were the reference, grading integrity would be compromised. Mitigation: the re-grade `Sandbox.task_dir` is the real host task dir (`rt.task_file.parent`), never the agent workspace (Detector-adjacent test in `tests/test_docker_regrade.py`). +5. **Baked image content.** Mocks/tooling baked into `docker/Dockerfile` must not encode task-specific expected values — authoring invariant + the baked-image scan (`tests/test_docker_image_no_answer_leak.py`). +6. **Env signposts.** `TASK_DIR`/`SKILLS_REPO_PATH` live on the grader (host) env only — never in the agent container's env (which has no task-dir/skills-repo mount to point at anyway). + ## Boundary | Layer | Location | |---|---| | Agent process (Claude Code SDK) | inside container | -| Sandbox + per-row criterion checking | inside container | -| **`task.json` serialization** | **container → host bind mount** | +| Sandbox setup + agent turn | inside container | +| **`task.json` (agent trajectory) serialization** | **container → host bind mount** | +| **Criterion checking / grading (GRADE-OUTSIDE)** | **host, after the container exits** | | Per-criterion `aggregate()` (P/R/F1, suite thresholds) | host | | Reports, run summary, experiment rollups | host | -`task.json` is the only artifact crossing the boundary.

The host then re-grades the copied-out artifacts (`regrade_on_host`) against the full criteria it holds, merges the authoritative grades onto the trajectory, and feeds the existing aggregation pipeline. The container never receives the criteria, reference, or graders (see [Isolation model](#isolation-model-copyprune--grade-outside)). A `result_kind` discriminator on `CriterionResult` ensures `ClassificationCriterionResult` subclasses survive the JSON round-trip — without it, host-side aggregation would silently lose `observed_label`/`expected_label`. diff --git a/src/coder_eval/cli/run_task_internal_command.py b/src/coder_eval/cli/run_task_internal_command.py index 3157e4a7..463c861d 100644 --- a/src/coder_eval/cli/run_task_internal_command.py +++ b/src/coder_eval/cli/run_task_internal_command.py @@ -169,7 +169,11 @@ def _watch_host_heartbeat() -> None: # Orchestrator's `task_file.parent` reasoning -- specifically the # `TASK_DIR` env exposed to `run_command` criteria -- resolves to the # original host task directory rather than `/work/input/`. - task, source_yaml = load_task(task_yaml) + # allow_empty_criteria=True: the staged task.yaml is agent_safe_dump-stripped + # (success_criteria: []) so the agent container carries no grading material; + # the host holds the real criteria and grades after the container exits.

Move them host-side: post_run runs after the container exits over the copied-out workspace; pre_run runs before the container into a staging dir that is seeded (files + directory trees) into the agent workspace. The container suppresses both. A guard redirects tasks whose pre_run must build an in-container env (uv sync / uip codedagent setup) to --driver tempdir for now, skipped per-task so the rest of a suite runs. Verified end-to-end under docker on Bedrock: host pre_run seed -> agent consumes it -> capture -> host post_run reads the output -> host grading.
