NemoClaw v0.0.120, dated September 4, 2026, adds secret-free verified configuration export and a global host and gateway doctor. NVIDIA's notes pin the managed Hermes runtime to 0.20.6, retire Shields from NemoClaw core, and move managed host forwarding onto detached OpenShell forward services. The same drop hardens sandbox recovery, onboarding, inference validation, MCP lifecycle operations, mTLS selection, and credential-bound messaging policy. For operators, the practical change is immediate. You can dump a fail-closed sandbox config without secrets, and you can run read-only host checks before onboarding—even with no sandbox selected. Managed Hermes stays on 0.20.6. ## Export writes a canonical document, and keeps secrets out `nemoclaw config export --output ` now writes a canonical `nemoclaw.nvidia.com/v1` configuration document after cross-checking registry, lifecycle, gateway, workload, image, inference, policy, and credential-reference state. The command keeps secrets out of YAML and JSON output and fails closed on inconsistent evidence. On Linux, file output uses owner-only atomic publication. `--output -` writes YAML to standard output on another supported host or in a pipeline. NVIDIA records the work as PR #11015. That fail-closed rule is the point. If registry, gateway, image, and credential-reference evidence do not line up, you do not get a half-checked document. You get a refusal. ## Doctor is global, read-only, and sandbox-optional `nemoclaw doctor` now runs read-only host and gateway checks before onboarding or without selecting a sandbox. It supports human-readable and redacted JSON reports, leaves gateway and sandbox state unchanged, and returns a nonzero status when a required check fails. Related change: PR #11012. Run it first. It is the pre-flight that does not touch gateway or sandbox state. ## Managed Hermes is 0.20.6 The managed Hermes runtime is now 0.20.6, with retargeted compatibility patches, reviewed lazy Hindsight dependencies, workspace-aware session previews, scheduled-task recovery, and the maintained managed-image security boundaries. Gateway startup preserves the validated lazy-install target for both direct root-entrypoint and OpenShell-managed same-UID topologies. Legacy rebuilds with no image hint now require the release-pinned immutable Hermes base and stop before mutation if it cannot be resolved and validated. Related changes: PR #10595, PR #11071, and PR #11024. Hermes Portable stopped-runtime recovery now reuses validated Podman and executable evidence inside each qualified lifecycle transaction, performs one bounded readiness wait inside the sandbox, and retries only transient final readiness-publication failures. Required host forwards settle together from a strict ownership snapshot with in-process TCP liveness checks. Full entry and final qualification, credential-bearing health, authority fences, and rollback remain enforced. Do not generalize this pin to a generic 0.20 line. NemoClaw's managed runtime in this release is 0.20.6. ## Shields is out of core; leftover state is preserved Shields has been retired from NemoClaw core, including its commands, plugin status, timers, policies, state-lock plans, and runtime-provider mutation contract. Upgrades preserve and report legacy Shields state instead of interpreting or deleting it. Affected installations must follow the printed fail-closed quarantine and rebuild guidance before ordinary mutation. Legacy OpenClaw migration also preserves the prepared rebuild context and exact candidate managed-image selection across replacement creation. Related changes: PR #10722 and PR #10996. That is a deliberate non-delete. The core surface is gone. The old bits stay reported, not interpreted, until you follow the quarantine path. ## Forwarding is now detached OpenShell services NemoClaw now uses detached `openshell forward service` processes for managed dashboard, messaging, and MCP host forwards instead of owning SSH forwarding processes and receipt state. The forward lifecycle follows sandbox and gateway availability, refuses an occupied host port, verifies reachability before success, and relaunches through normal recovery. MCP lifecycle work and typed policy reads also retain the sandbox's recorded gateway, workspace, TLS, and mTLS authority instead of inheriting ambient selectors. Related changes include PR #10695, PR #10814, PR #10815, and PR #10810. ## Onboarding, inference, MCP, and messaging fail closed more often Run doctor first. Then expect more refusals on these surfaces instead of mixed-evidence success. Onboarding fails closed when restore or authority checks fail. A validated managed snapshot can restore into a replacement sandbox before the replacement registry entry is published; if those checks fail, the snapshot is preserved and the replacement stays unregistered. Native Podman providers can own their Docker-less readiness checks. Qualified N1x users who decline the Deferred Express preview continue into ordinary provider selection. Managed vLLM preserves the catalog's served model when a resume checkpoint records a short alias. Plain sandboxes without a Portable receipt also avoid the Hermes lifecycle-lock path when they use a non-default gateway port. Inference status fails closed after retrying transient HTTP `429`, `502`, `503`, and `504` results up to three total attempts. Redacted JSON stdout and the final unhealthy result are preserved when every attempt fails. NVIDIA Nemotron 3 Super endpoint validation now sends its required sampling and chat-template parameters. The default Model Router pool replaces the retired Nemotron Nano route with GPT-OSS 20B High. Deep Agents MCP status fails closed on symbolic links, dangling symbolic links, FIFOs, and other unsafe managed projection entries instead of reporting an ordinary adapter mismatch. Snapshot restore can reconstruct the NemoClaw-owned projection through an atomic no-follow replacement while preserving directory targets for explicit operator recovery. Messaging and web-search provider setup fails closed unless the exact checked-in OpenShell profile verifies before registration or Ready reuse. An existing refreshing bridge keeps its working credential until replacement minting succeeds. Lookup, update, cleanup, and recovery failures remain distinct, redacted, and fail closed. Named gateway operations also reject an ambient OpenShell endpoint that could redirect provider preparation. Hermes Discord policy now authorizes only the Hermes and Python runtime binaries used for Discord traffic and removes the unused generic Node.js grant. Existing Hermes Discord sandboxes can reapply the maintained preset to remove the durable old grant without changing unrelated policy entries. ## Try doctor, then export Start on the host: run `nemoclaw doctor` before onboarding, and again without a sandbox if you need a baseline. Then export a sandbox with `nemoclaw config export` and inspect the `nemoclaw.nvidia.com/v1` document—YAML or JSON should carry no secrets, and inconsistent evidence should fail closed. If the install still reports legacy Shields state, follow the printed fail-closed quarantine and rebuild guidance before ordinary mutation. Treat managed Hermes as 0.20.6.
