deferredN1xOnboardingAdmitted remains true and enables the managed VLLM provider

src/lib/onboard/created-sandbox-n1x-finalization.test.ts (1)
191-193: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winCapture the create intent without a hard-coded argument index.
Line 192 reads
createSandbox.mock.calls[0]and line 193 selects position15. Theas unknown[]cast removes type checking on that read. If a parameter is added tocreateSandboxbefore position 15, this read returns a different argument andcreateIntentbecomesundefined. The two admitted cases then fail with a tuple mismatch that does not point at the real cause, and the two denial cases still pass for the wrong reason.Assert the call shape first, or capture the intent through a named override on the sandbox dep harness so the test breaks loudly at the capture site.
♻️ Proposed fix to fail at the capture site
- return { - admitted: preflight.context.deferredN1xOnboardingAdmitted === true, - createIntent: ( - sandboxHarness.calls.createSandbox.mock.calls[0] as unknown[] - )[15] as CreateIntent, - }; + const createSandboxArgs = sandboxHarness.calls.createSandbox.mock.calls[0] as + | unknown[] + | undefined; + if (!createSandboxArgs) throw new Error("Onboarding flow did not call createSandbox."); + const createIntent = createSandboxArgs.find( + (arg): arg is CreateIntent => + typeof arg === "object" && + arg !== null && + "deferredN1xManagedVllmPreviewIntent" in arg, + ); + return { + admitted: preflight.context.deferredN1xOnboardingAdmitted === true, + createIntent: createIntent ?? {}, + };Note that the
findform above only holds while exactly one argument carries that key. If two arguments could carry it, prefer an explicit dep override that records the intent.As per path instructions: "Prefer observable outcomes through the public boundary over source-text, private-shape, or mock-call assertions."

Outcome
Successful N1x managed-vLLM onboarding now records explicit Deferred preview acceptance. Rebuilds require that durable acceptance when registry normalization records both the derived endpoint and its source as
null; invalid or conflicting routes still stop before sandbox deletion.Reason
Registry normalization clears
endpointSourcewhen a local endpoint is derived instead of stored. The N1x rebuild gate cannot infer preview acceptance from that absence, so it needs a durable onboarding decision bound to the validated N1x route.Related issues

Maintainer verification requirement: retain one composed, table-driven test that carries the decision through real preflight, provider selection, sandbox create intent, and final registration. The isolated tests that duplicated this evidence were removed. The composed test reuses the existing provider and sandbox support factories, and the test-only production registration dependency was removed.
The first candidate inferred preview acceptance from absent route metadata. Commit
44a5193freplaced that inference with validated durable acceptance. Exact-head advisor review then found that ambientNEMOCLAW_PROVIDER=install-vllmcould mark non-N1x rebuilds; both managed-image discovery passes reproduced that failure.Commit
63fa94dfbinds the process-local decision to successful N1x preflight admission and the exact managed-vLLM provider/model. It also adds a production completion-to-registry test proving the durable field is written and clarifies the one-time recovery documentation.Commit
ea96a110consolidates the durable route qualification into one domain predicate and proves the complete fresh and resumed preflight-to-provider-to-sandbox-to-final-registration handoff. The paired DGX Spark and explicit-denial cases prove the marker and durable field stay absent.Commit
e6117bb4removes the isolated core-flow, preflight, and direct-registration tests now subsumed by that composed table.Commit
5f288f50adds the missing production-caller proof that an affected v0.0.119 null-route row readsNEMOCLAW_PROVIDER=install-vllmfromprocess.envand reaches authoritative readiness without pre-existing durable acceptance.Commit
4b3bf676separates explicit managed-vLLM preview acceptance from the broader N1x readiness waiver.NEMOCLAW_NO_EXPRESS=1may still admit ordinary onboarding, but it cannot create durable preview acceptance.Commit
b00841edrequires durable acceptance to use the exact normalized null/null route, adds production-caller rejection coverage for explicit recovery against endpoint/source/NIM/receipt conflicts, and removes the test-only production registration seam.Commit
8ba1f28aadds the one-time v0.0.119 N1x recovery command to the deferred channel-rebuild procedure and links its full conditions.Commit
7bc92247replaces the final-registration mock with an isolated real registry transaction and reload, proving successful onboarding durably publishes the acceptance field.Commit
63b3f4e3makes the reload mandatory and groups the one-time environment recovery under the required null/null route in both guides.Commit
4baf48eeproves a resumed legacyendpointSource: onboardroute normalizes to null before registration, then persists durable acceptance so the migrated row remains rebuildable.Commit
eeceedc3removes the redundant direct staging-helper test because the production-caller orchestration already proves the same explicit recovery behavior. The final PR is +692/−11 across 19 files: 143/3 production, 529/5 tests, and 20/3 docs.No physical N1x rerun was performed. The changed decision is deterministic registry and preflight state at the earliest stable boundaries.
