fix(onboard): resume a preset-driven managed vLLM install - #11271
Conversation
Resuming an interrupted managed vLLM profile install failed with "NEMOCLAW_SERVING_PRESET conflicts with NEMOCLAW_VLLM_MODEL" even though the operator had set neither variable. On resume, onboarding restores the recorded serving profile into NEMOCLAW_SERVING_PRESET, and the checkpointed install model is replayed as a model intent. That intent was written back into NEMOCLAW_VLLM_MODEL for selection, so NemoClaw's own record reached the guard that exists to reject an operator supplying two competing intents, and every documented recovery path was refused. A serving preset already names the model to install, so it stays the authority and the checkpoint is verified against what it resolves to instead of competing with it. The check runs after model resolution, so it covers preset selection, a fixed catalog profile, and the Station pair, and it rejects before any image pull or model download while leaving the session intact for --fresh. An operator-supplied NEMOCLAW_VLLM_MODEL is still rejected against a preset, and a resume without a preset still selects through the environment as before.

Observe the preset-selected model via the beforeInstall callback instead of inspecting the selection helper's mock call shape, so the test pins the installed model rather than resolver environment plumbing. Refs #11148 Signed-off-by: Yanyun Liao <yanyunl@nvidia.com>

Reviewed commit Blocking: managed-cluster resume bypasses the saved-model check. When a preset exists, the changed selection code removes the saved model from This is introduced by the change: previously, the cluster resolver received the saved model and could reject its conflict with the preset. Pass the saved model separately into the cluster installer and validate it before binding claims, checkpoint writes, image pulls, model staging, or container creation. Add regression coverage that includes the actual cluster selection/installer boundary and proves both matching success and mismatch rejection without those effects. The new host-local tests mock this branch as Manual evidence is required for the final revised commit. The existing DGX Spark narrative identifies the failing base commit, but the successful run names only
Local validation: 150 tests passed across |
The preset-authority change kept the resumed checkpoint out of NEMOCLAW_VLLM_MODEL, but the managed-cluster branch returns before the host-local revalidation and received no separate constraint. A mismatched checkpoint that cleared the existing cluster admission checks could then reach SSH binding claims, checkpoint replacement, image pull, model staging and container creation, and install the preset model over it. Carry the resumed model into the cluster installer and compare it against the materialized preset plan right after the plan is known, before the capability claim, the checkpoint write, and every download or container effect. Regression coverage now drives the real installer boundary for both the matching and the mismatching case, and asserts no effect runs on refusal.

Re-reviewed
Local validation: all 174 tests passed across the cluster installer, fixed-catalog installer, model aliases, and local-model-profile onboarder. The new tests cover mismatch rejection before effects and acceptance of a matching alias through the validation step. No live hardware test ran during this review. Manual evidence remains required before approval. The PR body still identifies the successful revision only as At this check, the OpenClaw managed-startup job and CLI shard 8 were still running, with no reported failures. This comment resolves the earlier code finding; approval remains pending the manual evidence and completion of applicable checks and automated reviews. |

@sandl99 Yes — manual evidence for the revised commit is below, along with the fix for the blocking finding. Blocking finding: managed-cluster resume bypassed the saved-model checkConfirmed, and it was introduced by my change exactly as you described. With a preset present the selection code removed the saved model from Fixed in
I verified the lock by removing the guard: the mismatch test fails immediately without it. Manual evidenceRun on our DGX Spark aarch64 test host (GB10 GPU), no other NemoClaw state present at start. Tested build 1. Real interruption after the managed container starts
Saved state after the interruption — both authorities recorded at once, which is the condition that produced the reported conflict: 2. Onboarding session and sandbox afterwards: 3. Successful inference response A real request against the managed backend, not just the readiness probe: For accuracy: my first attempt used 4. Controlled model-mismatch refusal From the same saved snapshot, with the checkpoint pointed at a different catalog model while the preset stayed unchanged: Preserved after the refusal: One correction so this is not overstated: the session file is not byte-identical after the refusal. A key-by-key diff shows 8 changed fields, all bookkeeping — Test scope note. The refusal above ran with the sandbox from step 2 already present, so it also shows the guard refusing while resources exist.

Approved commit 76bba709afd81cae9692a3e3f8a7ae3fb66c3bd2.
The manual DGX Spark evidence now identifies this commit and records interruption, resume exit 0, the completed session and expected model, a successful inference response, and mismatch refusal with saved intent and existing resources preserved. The disclosed bookkeeping updates do not contradict that preservation requirement. I reviewed this as author-provided hardware evidence; I did not rerun the hardware scenario.
The earlier cluster finding is resolved. All required GitHub checks pass, the managed-image checks have completed successfully, and all nine Advisor reports have been collected and assessed. CodeRabbit reviewed this commit with no actionable code finding.
Validation: 174 repository tests passed locally. Two supplemental reviewer checks also passed: public installVllm through the actual cluster installer rejects a mismatched saved model before claims or writes; a matching saved model completes the mocked cluster lifecycle, including staging, startup, receipt persistence, and binding cleanup. These supplemental tests were temporary and are not part of the PR.
Nonblocking: retain equivalent handoff and successful-resume regression coverage in the checked-in suite, as the Advisor recommends. The terminology and docstring suggestions are also advisory. No blocking code or evidence finding remains.

Summary
Resuming an interrupted managed vLLM profile install fails with
NEMOCLAW_SERVING_PRESET conflicts with NEMOCLAW_VLLM_MODEL, a conflict between two variables the operator never set, leaving the installation unrecoverable. This PR makes the serving preset the model authority on resume and verifies the checkpointed model against it instead of letting it compete.Closes #11148.

Analysis
The conflict is produced entirely from the interrupted state; the operator sets neither variable.
src/lib/onboard/command.ts:417— on--resume,resolveResumedServingProfilerestoresservingProfileProvenancefrom the persisted session, andapplyServingProfileEnvironment(command.ts:585) writes that preset id intoNEMOCLAW_SERVING_PRESET.src/lib/onboard/provider-recovery.ts:52,73— because the session carries a checkpointedvllmInstallModel, the non-interactive provider resolves toinstall-vllm(the[non-interactive] Provider: install-vllmline above) and that recorded model is passed down asmodelIntent.src/lib/inference/vllm.ts:1865—resolveVllmInstallSelectionEnvwrote that internalmodelIntentback into the selection environment asNEMOCLAW_VLLM_MODEL.src/lib/inference/serving/host-local-vllm-selection.ts:196-201— the guard that exists to reject an operator supplying two competing intents then sees a preset and a model together and rejects before catalog resolution.A clean run never reaches step 4 because there is no checkpointed model to replay, which is exactly the control comparison in the issue.
The pre-check is also strictly cruder than the rule the resolver already owns:
serving/resolver.ts:463-470accepts a model that matches the preset's recipe and only reports a conflict for a mismatch. The--profilepath additionally never reaches the dedicated local-model-profile onboarder, which already handles this same situation correctly by validating the resumed model against the materialized preset (local-model-profile/onboarder.ts:89-101) rather than passing it as a competing intent.Fix
The serving preset already names the model to install, so it stays the authority and the checkpoint becomes a verification input rather than a selector.
resolveVllmInstallSelectionEnvno longer writes the resumed model intoNEMOCLAW_VLLM_MODELwhen a serving preset is active; it carries it separately asresumedPresetModel. With no preset the previous behaviour is unchanged, so a non-preset resume still selects through the environment.resolvedso it covers every branch reachable on resume — preset selection, a fixed catalog profile, and the Station pair — rather than only the site that produced the report.--freshremains available and no user data is lost.Whole-class notes:
resolveVllmInstallSelectionEnvhas exactly one caller chain (resolveVllmInstallRequestEnv->runVllmInstall). Every consumer of the selection environment insiderunVllmInstallis covered — the fixed-profileexplicitModelgate (which previously also mis-fired on a preset resume withdoes not accept NEMOCLAW_VLLM_MODEL), the managed-cluster intent, bothresolveHostLocalVllmSelectioncall sites, and the Station-pair comparison. The two callers that passmodelIntentare the provider menu route and the local-model-profile onboarder; both are covered.Rather than add a second notion of alias matching,
vllmModelMatchesAliasis extracted from the existingresolveVllmModelAliasand reused, which also removes the duplicated inline comparison in the local-model-profile onboarder.Tests added to
vllm-fixed-catalog-install.test.tsdrive the real selection guard rather than a canned result:mainthis test emits the reporter's exact string.NEMOCLAW_VLLM_MODELagainst a preset is still rejected with the original message (regression lock).The existing test pinning the no-preset resume path (
replays and refreshes a checkpointed model before Docker download work) is untouched and still passes.Changes
src/lib/inference/vllm.ts: keep the resumed checkpoint out ofNEMOCLAW_VLLM_MODELwhen a preset is active, and verify it against the resolved model.src/lib/inference/vllm-models.ts: extractvllmModelMatchesAliasfromresolveVllmModelAlias.src/lib/onboard/local-model-profile/onboarder.ts: reuse that helper instead of a duplicated inline comparison.src/lib/inference/vllm-fixed-catalog-install.test.ts: three cases covering the fixed behaviour, the mismatch boundary, and the operator-override regression lock.Type of Change
Verification
npx prek run --all-filespassesnpm testpasses (touched files at minimum)make docsbuilds without warnings (doc changes only)No docs change: this restores the already-documented recovery behaviour rather than changing it, and adds no new environment variable or flag. The one new message is an internal-consistency rejection that states its own recovery action inline.
Note on platform scope: the issue reports DGX Spark only and that is where this was reproduced and verified. The defect is in provider-selection plumbing rather than anything arch-specific, so it should apply equally on x86_64, but that was not exercised on hardware here.
