When a mutation adds an .mjs plugin, this include loads it into the dsh Node process that rollout_driver.py launches directly on the evaluator host. Such a plugin can import node:fs or node:child_process, inherits model credentials, and runs as the same user that has Docker access, allowing it to read frozen workspace data or manipulate task and concurrent-trial containers instead of using the intended docker exec bridge. This breaks the trusted scoring boundary described in docs/concepts/design.md; execute candidate plugins in an isolated worker with access only to the intended task channel.

When dsh fails before completing a task—for example because a candidate plugin cannot boot or the SDK/API raises—the subprocess returns nonzero, but this path only logs the status and returns normally. Harbor consequently treats the agent phase as successful, proceeds to verification, and records the resulting empty or partial task state as a benchmark score instead of an agent failure eligible for the configured retry/error handling, contaminating parent and gate results. Classify or raise on nonzero return codes.

On a host running Node 22.0 through 22.18, this pattern accepts the executable even though dsh requires Node 22.19 or newer. Preflight therefore succeeds and the later SDK/runtime startup can fail after evaluation work has begun; compare the minor version when the major version is 22 rather than accepting every 22.* release.

DSH_HARNESS_REPO is required rather than labeled optional, and ensure the
documented setup path provides this repository location before the installation
commands use it. Do not introduce an alternative dependency source.
In `@evals/agents/dsh/recipe/evaluator/prepare-runtime.sh`:
- Around line 17-21: Update the NODE_VER case check in prepare-runtime.sh to
reject Node 22 versions below 22.19 while continuing to accept Node 22.19+ and
later major versions. Preserve the existing fail behavior for unsupported
versions before starting the evaluator.
In `@evals/agents/dsh/recipe/stage_scripts/validate_node_check.py`:
- Around line 36-42: Update the profile validation try/except around
yaml.compose and profile.read_text to also catch UnicodeError and OSError,
append the corresponding profile.cordis.yml problem, and allow validation to
return accept=False instead of propagating unreadable-file errors.
In `@evals/agents/dsh/runners/compositions/mutate.cordis.yml`:
- Around line 29-33: Update the sandbox-policy configuration to use mode
workspace-write and root the mutation workspace at DSH_CWD, preserving the
existing workspace-root intent without full-access permissions. Keep broader
operations outside the candidate-controlled mutation session.
In `@evals/agents/dsh/runners/compositions/rollout.base.cordis.yml`:
- Around line 35-45: Isolate candidate-owned plugins loaded by
candidate-composition from the DSH host process, especially the host environment
containing DEEPSEEK_API_KEY. Update the sandbox configuration around
`@deepseek-ai/dsh-sandbox-local` and `@deepseek-ai/dsh-sandbox-policy` to run
plugins in a separate sandbox with a filtered environment, or restrict the
mutable candidate profile to declarative components; do not rely solely on
terminal-bash isolation.
Apply the same fix in `@evals/agents/dsh/seed/profile.cordis.yml` around lines 1 -
2: The profile composition loads executable files from the mutable candidate
surface.
In `@evals/agents/dsh/runners/mutate_local.py`:
- Around line 104-114: Update the retry loop in the local mutation runner so the
final return value preserves the last driver status from _run_driver: return
zero only when the final no-change attempt succeeded, and return its nonzero rc
when all attempts fail without target/ changes. Keep the existing immediate
success path when changed is detected.
- Around line 84-88: Update workspace setup and preflight around the interpreter
selection in mutate_local.py to ensure EVOLVE_WORKSPACE/.venv contains
deepseek-harness-sdk and the editable deepseek-harness-runtime-bin dependency,
installing them during prepare-runtime.sh or failing preflight when the required
imports are unavailable. Ensure dependency failures propagate as a nonzero exit
status instead of allowing exhausted mutate_driver.py failures to return
success.
In `@evals/agents/dsh/runners/rollout_driver.py`:
- Around line 21-32: Update the Docker inspection in the rollout driver to
invoke the executable configured by DSH_DOCKER_BIN, matching terminal-bash, and
set subprocess.run’s check option to true so inspection failures propagate
instead of falling back to the root directory.
In `@evals/agents/dsh/seed/dsh_trajectory.py`:
- Around line 122-132: Update convert_session and its extraction flow to
preserve global execution order when combining JSONL files: retain each record’s
documented timestamp or sequence metadata, collect events across files, and sort
them by that total-order field before producing steps. If no cross-session
ordering field exists, avoid flattening parent and subagent streams and emit
separate trajectories instead.

DeepSeek Harness dsh sandbox-policy danger-full-access workspace-write workspaceRoot
💡 Result:
In the DeepSeek Harness (dsh) architecture, the sandbox policy is managed by the @deepseek-ai/dsh-sandbox-policy package, which is accessible via the ctx.sandboxPolicy service [1][2][3]. This service acts as the central authority for deployment-wide sandbox configurations [2][3]. Key concepts associated with this service include: 1. Sandbox Modes: The system uses modes to govern filesystem effects [1][4]. - read-only: Limits command execution to read-only access (the default fail-safe) [3][4]. - workspace-write: Permits writes within the defined workspace root and the system's temporary area [4]. - danger-full-access: Bypasses sandbox confinement entirely [4]. This mode is intended only for situations where broad, unrestricted access is required [1][4]. 2. workspaceRoot: This property serves as the fallback root for agentless calls or sessions where a current working directory (cwd) is not available [3][4]. Under normal operation, tool calls automatically derive the workspace root from the immutable cwd of the active session [1][4]. 3. Policy Resolution: The ctx.sandboxPolicy service resolves the effective sandbox policy for each capability call by combining the deployment's default mode and the fallback workspace root with the specific request's requirements [1][5]. Because it is a centralized service, it ensures that different components, such as bash and filesystem sandboxes, consistently apply the same confinement boundaries [2][3]. The danger-full-access flag is explicitly included in the resolved execution policy, allowing consumers to verify policy settings before deciding whether to bypass confinement [1][4]. When a consumer uses danger-full-access, it typically spawns the original argv directly rather than utilizing the standard ctx.sandbox provider [4].

Isolate mutable candidate plugins and restrict their capabilities.
The candidate’s mutable plugin files execute with evaluator-process privileges and inherit environment values that include API credentials. A self-modified plugin can therefore read workspace data or credentials and perform unrestricted process or network operations. Execute candidate-owned plugins in an isolated process with a filtered environment and explicit capability allowlist, or keep executable sources outside the mutable surface.

💡 Result:
DeepSeek Harness (dsh) is an open-source agent development platform created by DeepSeek AI [1][2]. It is currently in developer preview and features a modular, plugin-based architecture powered by Cordis [1][3]. There is a distinction between the official DeepSeek Harness project and a separate package sharing a similar name: 1. Official DeepSeek Harness (deepseek-ai/deepseek-harness): This is an agent harness where every capability (models, tools, skills, sessions, etc.) is implemented as a plugin [3]. - Python SDK: The official Python support is provided via the deepseek-harness-sdk package on PyPI [4][5]. - Module Name: Despite the distribution name deepseek-harness-sdk, the Python code is imported using from deepseek_harness import DeepSeekHarness [4][5]. - Runtime: The SDK works by spawning a JSON-RPC subprocess. It relies on a companion runtime package, deepseek-harness-runtime-bin, which provides the necessary dsh-jsonrpc-agent executable [4][5][6]. - Official GitHub: https://github.com/deepseek-ai/deepseek-harness [1]. 2. Independent Package (deepseek-harness): There is a separate, unrelated Python package named deepseek-harness available on PyPI (v0.2.0) [7]. - This is a protocol-aware Python client for DeepSeek V4-Pro/Flash models, maintained by an independent developer (Henry Zhang) [7]. - It is not part of the official DeepSeek AI agent harness platform [7]. To use the official DeepSeek Harness in Python, you should install deepseek-harness-sdk [4][5]. The runtime environment automatically manages configurations via DSH_CORDIS_CONFIG, or you can provide a custom Cordis configuration file to orchestrate your specific plugin composition [4][6].

Enforce the deepseek_harness workspace dependency
prepare-runtime.sh does not install or check Python dependencies. Ensure the workspace setup installs deepseek-harness-sdk and its editable deepseek-harness-runtime-bin companion into EVOLVE_WORKSPACE/.venv, or fail preflight with an import check. Otherwise mutate_driver.py can raise ModuleNotFoundError, while exhausted failures still return exit code 0.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Use the configured Docker executable and fail on inspection errors.
terminal-bash uses DSH_DOCKER_BIN, but this inspection always invokes docker. If the evaluator configures a Docker-compatible executable at DSH_DOCKER_BIN, the driver can fail before the session starts.
Use the same executable here. Set check=True so an invalid container ID or failed Docker command does not silently select / as the working directory.

Preserve event order when merging session files.
Line 126 orders files by pathname, then emits each file as one block. If parent and subagent session streams interleave, steps no longer represents execution order. Evidence operators can then analyze a false trajectory.
Extract the documented global timestamp or sequence field before discarding record metadata, then sort all events by that field. If DSH has no global ordering field, preserve each session as a separate trajectory instead of flattening them.
What is the DeepSeek Harness `dsh-session-persistence-jsonl` schema for parent and subagent sessions, and which field provides a total chronological order across session JSONL files?

New supported recipe recipes/hyperagents_dsh (HyperAgents selection and recording over the built-in dsh target) plus its parts in their native homes: - seeds/dsh: dsh's own agent profile as the evolvable target (cordis composition + plugins + skills + lineage PLAYBOOK), with the harness pieces shipped alongside under surface.exclude — the host-side Harbor adapter (agent.py), the session-log-to-trajectory.json converter, the SDK drivers, and the frozen rollout/mutation cordis compositions. The mutate stage is runner: local — a dsh self-modification session in the child worktree rewrites its own persona, plugins, and skills. - library/validate/node_check.py: new validate operator running node --check on evolved plugins plus a tag-tolerant YAML syntax check, rejecting syntactically broken candidates before a full evaluation. - src/evolve/workspace.py: register the builtin-dsh seed. - recipe evaluator assets: prepare-runtime.sh pins Node >= 22.19 and forwards optional restricted-network compensations; doctor.json enforces it before every run. - tests and docs updated for the new inventory entry; a dedicated composition test covers builtin-dsh initialization. Recorded end-to-end run (30-task Terminal-Bench 2 subset): certified genesis 0.700, a gate rejection (0.667 < parent) and a gate acceptance (0.700 >= parent, dsh-authored skill) across three evolved generations.

runner: localanchors a dsh self-modification session in the child worktree, which reads the failure evidence and rewrites its own persona, plugins, and skills. Analyze operators (trace_browseretc.) work unchanged because the adapter converts dsh's event-stream session log into thetrajectory.jsonshapelibrary/_shared/harbor/evidence.pyconsumes.No absolute paths anywhere: the seed's
runners/are resolved relative to the adapter, the mutate command ispython3 target/runners/mutate_local.py(cwd = child checkout), and endpoint routing follows the workspace's frozen identity (OPENAI_BASE_URL/OPENAI_API_KEYmapped onto dsh'sDEEPSEEK_*).Why
The candidate contract is agent-runtime-agnostic in practice — the workspace machinery never interprets
target/, and the evaluator agent is any host-side HarborBaseAgent. This makes that concrete with a real non-Python, non-MiniSWE harness, and gives the next runtime integration a worked pattern: seed-side adapter + relative runners + a validate guard for the target's native language.One setup step is inherently manual and documented in the recipe README: the dsh Python SDK is not on PyPI, so it joins the workspace runtime via
uv addfrom a dsh clone (the documented extension path in the generatedAGENTS.md).Evidence
