Reuse the dependency-only repair from #12502 while retaining OpenClaw 2026.9.1. Pin the audit implementation to verified commit b0af4ef. Reuse verified AMD64 and ARM64 receipts with identical Pi image inputs. Existing tests, audit thresholds, and native plugin provenance stay intact.

Tested on a 128 GB DGX Spark (GB10) at commit 4eb9bd4. Local onboarding, inference, and actual tool execution worked. The constrained 64 GB profile also passed the functional checks below, with an existing CLI result-classification problem affecting tool turns. This covers the tested commit, not subsequent PR updates. Environment: Linux aarch64, NVIDIA driver 580.159.03, OpenShell 0.0.116, OpenClaw 2026.9.1. Used the source-built CLI and direct onboarding with Express's managed-vLLM settings; the hosted curl installer was not tested. Normal 128 GB run
Constrained 64 GB profile runExplicitly selected A test-only launch adapter capped the vLLM container at 61,614,325,760 bytes with no swap. CUDA still reported the physical 128 GB despite the cgroup cap, so the adapter adjusted GPU memory utilization from Results:
Limitation: this is a constrained functional pass on physical 128 GB hardware. The profile was explicitly selected, the utilization setting was adjusted, and the memory cap covered the vLLM container rather than the entire host. Automatic detection and an unmodified launch on a physical 64 GB Spark still need validation. Separate

NVIDIA#12502 added a corroborated replay-risk classifier on main. Keep it as the base and narrow this change to the cases it still gets wrong: - Accept a completed tool turn whose visible text starts with reply directives, or carries MEDIA: lines that the payload holds as media. - Keep replayInvalid incomplete for a declared liveness state other than working, a pending continuation, a timed-out turn, or OpenClaw's no-final-answer fallback reply. A missing liveness state stays accepted, as main's tests expect. Validation: these tests fail in 20 cases against main's classifier and pass with this change, along with main's own tests. vitest for src/lib/openclaw and src/lib/actions/sandbox/agent (402), the E2E-support output tests (51), growth guardrails, typecheck:cli, oxfmt, oxlint, and the commit hooks pass.

Outcome
Managed local Qwen setup automatically selects a bounded serving recipe for a nominal 64 GB DGX Spark and displays its profile and context limit before installation. Successful OpenClaw tool turns retain exit status 0 when their metadata marks replay unsafe.
Reason
The existing Spark recipe requires 64,000,000,000 detected bytes, excluding the reviewed device's 61,614,325,760 bytes. Hardware testing also exposed an existing result-classification defect:
replayInvaliddescribes replay safety, but NemoClaw treated it as an incomplete turn even when tools finished successfully.Changes

4eb9bd4d5cf8d37a13ae540638cea384f5527250on a physical 128 GB DGX Spark. Normal onboarding, inference, actual file/exec tools, and restart recovery passed with the larger profile.The explicitly selected 64 GB profile also passed chat, verified native tools, restart recovery, and a 30,037-token prompt with the vLLM container capped at 61,614,325,760 bytes and no swap. GPU utilization was adjusted for the physical 128 GB device to produce the intended 30,807,162,880-byte executor budget. Peak observed container memory was 41.3 GB without OOM events.
This is constrained functional evidence, not an unmodified run on physical 64 GB hardware. Automatic detection on that hardware and the hosted curl installer were not tested. The recipe remains experimental and software-validated. The release updates

Self-review covers the complete NVIDIA/NemoClaw diff at
e07a7551265de3992b0a345d0e4ac5731e01a733, including admission limits, result classification, unchanged failure paths, and preserved E2E evidence. No independent approval is claimed. Main CI, managed-image validation including Docker and rootless Podman activation, and self-hosted qualification pass one07a7551265de3992b0a345d0e4ac5731e01a733. CodeRabbit reviewed that commit with no actionable comments. The prior SDK connection failure did not recur; lifecycle code is unchanged, so no causal runtime repair is claimed.All nine Advisor specialists completed for this commit. Eight ledgers are clear. Security finding
F-security-built-in-quality-611fded04775f90e9de8is classified as a false positive: it requests independently authenticated completion receipts from a parser that classifies OpenClaw process output. All existing completion markers, includingreplayInvaliditself, come from that same response; a compromised runtime could already omit the flag or sendfalse. Rejecting every true flag cannot authenticate the response and would restore the demonstrated failure for legitimate completed tool turns. This change grants no host privilege and initiates no replay. Uncertain outcomes remain non-zero, with the raw trace and inspect-before-retry guidance preserved.The automated Advisor blocker job remains red; its finding is retained. The manual disposition follows the repository PR follow-up rule for false positives and the merge guide's treatment of Advisor output as review input rather than approval authority. Physical 64 GB Spark recommendations remain deferred under the documented experimental, software-validated scope; the existing hardware report is a constrained 128 GB run. No claim of physical 64 GB qualification or a full manual E2E fanout is made.

The existing larger-memory profile should retain 262,144 context tokens and four sequences.
