Verification & Compatibility○ Ecosystem plugin

Grouped by plugin version: each card lists the dsh versions actually tested against that artifact version and their install verdicts (L5 wins). Untested combinations are omitted — absence means untested, never assumed compatible. L1–L3 are a plugin-level static archive (independent of the dsh version — the same verdict on every dsh row): they sit in each row's level grid next to L4/L5, marked "static", while their evidence is stored once per plugin inside that row's "checks & evidence" instead of being duplicated per version.

Security Report

Two automated layers, neither a manual review: a static scan (per-plugin rule checks) and a model-driven dynamic security audit that covers only the subset static-flagged at warn or above and never executes plugin code.

lowModel code in the kernel inherits the full host environment (process.env)packages/code-runtime-kernels/src/index.ts
Any credential in the harness process environment (model/API keys, tokens) is readable by model-generated kernel code and can be echoed back in logs or the completion value; with sandboxConfinement defaulting to false the kernel can also reach the network. This is consistent with the plugin's documented bash-equivalent trust model, hence low, but the model-facing tool description never mentions it.
lowNamespace snapshots are Python pickle deserialized by the kernel from a user-writable directorypackages/code-runtime-kernels/src/python/runner.ts
Restoring a session snapshot executes pickle opcodes. The file path is ~/.dsh/code-runtime-kernels/state/<lang>/<sha256(lang:sessionId)>.snapshot, and session ids are model-chosen, so code running in one kernel (or anything running as the same unix user) can pre-plant another session's snapshot and get code execution in that kernel on its next restore. No privilege escalation is gained — the attacker already runs with bash-equivalent trust — so this is a low-severity state-injection/integrity gap; the code comments acknowledge pickle is not a security boundary.

Persistent Python/JS kernel tool that runs model code in spawned subprocesses by design; host-side frame validation and process-group teardown are solid, leaving only low-severity env/pickle exposure.

Rule: the dynamic audit can only raise risk, never lower it (raise-only, never an exemption); a wrong raise is withdrawn by human review and the tier falls back to the static verdict. Overall verdict = the stricter of the two layers.

Disclaimer: the static scan and the dynamic security audit are both automated analysis, not a security guarantee. Always review what you install.

Plugin notes

What is @hy-sde/dsh-code-runtime-kernels?

@hy-sde/dsh-code-runtime-kernels is an ecosystem plugin maintained by @hy-sde: it installs via dsh plugin add but declares no dsh.bundle and mounts nothing — installing it adds no plugin capability; use the source repository directly. It is cataloged on dsh.so as a Developer entry, with a public source repository and automated static security scan.

How do I install @hy-sde/dsh-code-runtime-kernels?

This is an ecosystem plugin: it installs via dsh plugin add but declares no dsh.bundle and mounts nothing — installing one adds no plugin capability; use the source repository directly. Its level reads L5 · Ecosystem plugin; the security scan still runs.

How does the security scan relate to a manual audit?

Both layers are automated, not a manual audit: the static scan is heuristic analysis of the repository source (it can produce false positives and miss context), and the dynamic security audit has a model read the harvested source context with secret files stripped and content redacted inline — plugin code is never executed. The dynamic audit only covers plugins static-flagged at warn or above, and its conclusion can only raise the combined verdict, never exempt it. Neither layer is a manual security audit or an endorsement; before using a plugin, review the repository and installed permissions, and combine both with the verification level (L4/L5) and health signals.
