## Summary Bumps the pinned OpenShell version range from `0.0.29` → `0.0.32` so fresh NemoClaw installs pick up sandbox hardening and TLS improvements from the last three OpenShell releases. ## Notable upstream changes **0.0.30** ([NVIDIA/OpenShell@v0.0.29...v0.0.30](NVIDIA/OpenShell@v0.0.29...v0.0.30)) - Network policy deny rules ([OpenShell#822](NVIDIA/OpenShell#822)) - Preserve ownership on existing `read_write` paths ([OpenShell#827](NVIDIA/OpenShell#827)) - Disable child core dumps ([OpenShell#821](NVIDIA/OpenShell#821)) - Escape control characters in SSE error formatting ([OpenShell#842](NVIDIA/OpenShell#842)) - Fix silent truncation of large streaming inference responses ([OpenShell#834](NVIDIA/OpenShell#834)) **0.0.31** ([NVIDIA/OpenShell@v0.0.30...v0.0.31](NVIDIA/OpenShell@v0.0.30...v0.0.31)) - Inference routed-request header allowlist ([OpenShell#826](NVIDIA/OpenShell#826)) **0.0.32** ([NVIDIA/OpenShell@v0.0.31...v0.0.32](NVIDIA/OpenShell@v0.0.31...v0.0.32)) - **Load system CA certificates for upstream TLS connections** ([OpenShell#862](NVIDIA/OpenShell#862)) - Publish standalone `openshell-gateway` binaries ([OpenShell#853](NVIDIA/OpenShell#853)) ## Changes - `nemoclaw-blueprint/blueprint.yaml`: `min_openshell_version` and `max_openshell_version` → `0.0.32` - `scripts/install-openshell.sh`: `MIN_VERSION` and `MAX_VERSION` → `0.0.32` (`PIN_VERSION` follows `MAX`) - `scripts/brev-launchable-ci-cpu.sh`: default `OPENSHELL_VERSION` → `v0.0.32` - `src/lib/onboard.ts`: blueprint-fallback min version → `0.0.32` - `test/onboard.test.ts`, `test/install-openshell-version-check.test.ts`: fixtures updated; "above MAX" test case moved from `0.0.30` to `0.0.33` Historical `m-dev` comments referencing `0.0.29` left in place — they describe a self-report quirk the sidecar fallback still handles. ## Why not 0.0.33+? `0.0.34` introduced incremental sandbox policy updates and L7 request-target canonicalization — changes with larger surface area against how NemoClaw delivers policy via gRPC. Worth a follow-up PR rather than bundling here. `0.0.35` released hours before this PR was cut — too fresh. ## Type of Change - [x] Code change for a new feature, bug fix, or refactor. ## Testing - [x] `npx vitest run test/install-openshell-version-check.test.ts` — 9 passed - [x] pre-commit hooks (prek) clean: shellcheck, commitlint, gitleaks, YAML validator, CLI test suite - [ ] Nightly E2E on this branch — will be kicked off after PR opens ## Notes - No user-facing CLI behavior changes — just the pinned version range. - Two pre-existing failures in `test/onboard.test.ts` reproduce on clean `main` and are unrelated to this bump.
