fix(status): stop attributing an upstream credential rejection to the sandbox route

[laitingsheng]

Summary

$$nemoclaw <name> status reported Inference (upstream): unauthorized (HTTP 401) whenever the host credential it resolves differed from the provider credential the gateway stores, even though the sandbox route had already served the inference request with the stored credential. The upstream check now reports not probed in that case and names both credential sources, so the operator is no longer directed at a credential that is not in the failing path.

Related Issue

Fixes #9595

Changes

• src/lib/actions/sandbox/inference-route-health.ts: providerHealthDiagnostics takes whether the route served an inference request. When it did and the upstream check reports unauthorized, that check becomes ok: true, probed: false with a detail naming the host credential, the stored provider credential, and the fact that NemoClaw does not attribute the result to the sandbox route.
• src/lib/actions/sandbox/inference-route-health.ts: local backend and auth proxy hops carry their own probeLabel, so the rewrite is scoped to upstream and leaves Inference (auth proxy) and Inference (vllm backend) reporting their own state and their own repair step.
• src/lib/inference/health.ts: an unauthorized model-invocation result now names the endpoint as the actor, states that the probe authenticates with the host credential in the credential environment variable rather than the provider credential stored in the gateway, and drops the network-connection advice that does not apply to a rejected credential.
• docs/reference/commands.mdx: states which credential each host-side check uses, why the two credentials can hold different secrets, when Inference (upstream) reports not probed, and that doctor always reports the state it measured because it sends no inference request.
• src/lib/actions/sandbox/status-snapshot-inference-health.test.ts: four tests covering the not probed rewrite, an unreachable upstream check, an unauthorized auth proxy subprobe, and an unauthorized upstream check when the route did not serve a request.
• src/lib/inference/health.test.ts: one test asserting the reworded unauthorized detail.

The rewrite is a reporting decision rather than a new fallback path, so its current requirement, consumer, and protecting test are:

• Current requirement: the OpenShell gateway is the system of record for provider credentials and does not return their values (src/lib/credentials/store.ts), so a host-side probe cannot authenticate with the credential the sandbox route uses. It can only report on the credential it resolves.
• Consumer: buildSandboxInferenceRouteHealth, reached from collectSandboxStatusSnapshot for $$nemoclaw <name> status.
• Why a direct change is insufficient: authenticating the probe with the stored provider credential would require a gateway path that returns credential values, which the credential design refuses.
• Protecting test: reports the upstream check as not probed after the provider rejected the host credential and the route served a request (#9595) and keeps an unauthorized auth proxy subprobe after the route served a request (#9595) in src/lib/actions/sandbox/status-snapshot-inference-health.test.ts.

One existing test changed. keeps an upstream subprobe failure out of the served-route verdict (#6846) used an unauthorized fixture, which is the exact reporting this change corrects. Its fixture is now unreachable and its title names that failure, so it still protects the #6846 contract that an upstream failure does not flip the served-route verdict.

📝 Walkthrough

Walkthrough

The change updates unauthorized provider diagnostics, distinguishes host and gateway credentials, and attributes upstream results based on whether the managed inference route served a request. Tests and command documentation cover successful routes, provider failures, and status versus doctor.

Changes

Inference diagnostics

Layer / File(s)	Summary
Provider credential diagnostics src/lib/inference/health.ts, src/lib/inference/health.test.ts	Unauthorized provider responses now identify the host credential environment variable and exclude gateway-credential and network guidance.
Route-health attribution and command behavior src/lib/actions/sandbox/inference-route-health.ts, src/lib/actions/sandbox/status-snapshot-inference-health.test.ts, docs/reference/commands.mdx	Successful managed inference routes convert unauthorized upstream results to unprobed, unattributed results. Other upstream and auxiliary failures remain independent. Tests and documentation describe the resulting status and doctor behavior.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 404c2

This change updates inference, sandbox, and credential-reporting behavior, but the required sensitive-path review or maintainer waiver is not recorded. The targeted validation passes; merge should wait until that review or waiver is completed.

2 semantic terminology decisions

Terminology decisions are advisory. They affect the assessment only when a separate finding identifies concrete semantic impact.

• established — upstream at docs/reference/commands.mdx:2028: Keep `upstream` for the labeled host-side diagnostic because the nearby text defines its credential boundary.
• established — host credential at docs/reference/commands.mdx:2028: Keep `host credential` because repository usage establishes it and the changed text distinguishes it from the provider credential.

E2E guidance

Advisory only. A maintainer can dispatch the default E2E suite for the commit under review.

Recommended E2E: inference-routing

Maintainer review: PASS

Correctness and documentation

• The CodeRabbit finding was valid. The rewritten upstream diagnostic now retains the original provider-probe detail, including the host credential environment variable, while explaining why the result is not attributed to the sandbox route.
• The regression test now requires NVIDIA_INFERENCE_API_KEY to remain in the transformed detail.
• The command reference owns this user-visible behavior and clearly distinguishes the host credential from the provider credential stored in the gateway.

Security review: PASS

• Input and command handling: PASS — no new external input, shell command, or argument construction.
• Secrets and diagnostics: PASS — the change names a credential environment variable but never reads or prints a credential value.
• Network and SSRF: PASS — endpoint selection and request behavior do not change.
• Authentication and authorization: PASS — the gateway remains the system of record for the provider credential; no read-back path is added.
• Dependencies and artifacts: PASS — no dependency, workflow, or artifact change.
• Sandbox and host boundary: PASS — the change only classifies an existing host-side diagnostic after the sandbox route served a request.
• Failure behavior: PASS — unauthorized, unreachable, auth-proxy, and no-served-request cases remain distinct and covered.
• Concurrency and lifecycle: PASS — no process, retry, or shared-state change.
• Data integrity and persistence: PASS — no stored state or schema change.

Validation

• npm run build:cli passed.
• The four focused status, doctor, and inference suites passed: 145 tests.
• npm run typecheck:cli, npm run checks:repository, and npm run test:changed passed.
• npm run docs passed with 0 errors and the two warnings already present on main.
• The initial isolated test attempt stopped before test execution because generated build artifacts were absent. Generating those artifacts resolved the setup condition; no PR failure remained.

Compliance and size

• The original contributor commit and attribution remain in the branch.
• The maintainer commits are signed off and GitHub-verified.
• Net change is +199/-4 across five focused files, including 150 test and documentation lines. This is not a large change.

Fresh CI and automated review are now running. I will continue monitoring them.
