fix(onboard): preserve N1x preview intent on rebuild

[sandl99]

Summary

NemoClaw rebuild readiness previously recognized N1x managed-vLLM preview intent only from the transient installer environment. Rebuild now derives that intent from the exact recorded N1x route, including the physical v0.0.109 state where endpointUrl and hostLocalInferenceReceipt are null, and carries it through pre-delete and cached-resume readiness.

Fixes #9292

Changes

• Admit the Deferred N1x exception only for vllm-local, nvidia/Qwen3.6-35B-A3B-NVFP4, endpointSource: onboard, and the Docker OpenShell driver.
• Treat endpointUrl: null as the derived canonical local endpoint; accept the exact explicit canonical URL and reject every other non-null endpoint.
• Accept an absent or null v0.0.109 receipt; require any present receipt to identify matching canonical vLLM inference.
• Carry the verified internal decision through authoritative pre-delete readiness and both cached-resume host checks without relying on ambient NEMOCLAW_PROVIDER.
• Add positive coverage for the exact physical registry state and matching receipts, plus negative coverage for route, source, driver, and receipt conflicts.
• Document the rebuild compatibility rule and unchanged Deferred status.

Type of Change

• Code change (feature, bug fix, or refactor)
• Code change with doc updates
• Doc only (prose changes, no code sample modifications)
• Doc only (includes code sample changes)

Quality Gates

• Tests added or updated for changed behavior
• Existing tests cover changed behavior — justification:
• Tests not applicable — justification:
• Docs updated for user-facing behavior changes
• Docs not applicable — justification:
• Sensitive paths changed (security, policy, credentials, preflight, onboarding, inference, runner, sandbox, or messaging)
• Sensitive-path review completed or maintainer-approved waiver recorded — reviewer/approval link/justification: Review confirmed that live N1x identity, the exact recorded route, the rebuilt provider and model, and any present receipt must agree. Missing or false intent remains fail closed. Explicit false pre-delete intent suppresses ambient provider state.
• Non-success, skipped, or missing CI check accepted by maintainer — check name, approval link, and follow-up issue:

Documentation Writer Review

• Documentation writer subagent reviewed the completed changes
• Result: docs-updated
• Evidence: Updated docs/inference/set-up-vllm.mdx. Reviewed the complete implementation through a3237565f for claim accuracy, terminology, structure, voice, and fail-closed behavior. Verified that endpointUrl: null derives the canonical local route, the exact canonical URL remains eligible, other non-null endpoints are denied, and verified intent reaches authoritative preflight and cached resume. The final six-file review follow-up only moves the pure eligibility decision into the domain layer and preserves action-layer mutation and runtime behavior. Original focused and changed-path tests passed; the follow-up passed 28 focused tests, 103 changed-path tests, CLI type-checking, repository architecture checks, git diff --check, and normal commit and push hooks. The docs build passed with 0 errors and 2 existing warnings.

Verification

• PR description includes a Signed-off-by: line and every published commit appears as Verified in GitHub
• Normal pre-commit, commit-msg, and pre-push hooks passed
• Targeted behavior tests pass for the current change set — 6 files and 97 tests passed; npm run test:changed passed 116 files and 1,494 tests; npm run typecheck:cli passed
• Applicable broad gate passed — not selected because the change is confined to existing rebuild-readiness paths and the affected suites passed
• Quality Gates section completed with required justifications or waivers
• No secrets, API keys, or credentials committed
• npm run docs builds without warnings (doc changes only) — build passed with 0 errors and 2 existing warnings
• Doc pages follow the style guide (doc changes only)
• New doc pages include SPDX header and frontmatter (new pages only)

Physical N1x diagnosis at 71992f60e confirmed that source and compiled revisions matched, N1x identity was qualified, ambient provider intent was unset, and the raw registry stored the exact provider/model/source/driver tuple with endpointUrl: null and hostLocalInferenceReceipt: null. The previous predicate incorrectly required the raw endpoint to contain the canonical URL. Physical retest of 6b26b724f passed on N1x.

Summary by CodeRabbit

• New Features
  • N1x sandbox rebuilds can reuse a previously recorded managed vLLM inference route when provider, model, endpoint, driver, and receipt details are compatible.
  • Rebuilds support recognized missing or null inference receipts from older versions.
• Bug Fixes
  • Incompatible, conflicting, or malformed route receipts now stop rebuild readiness before sandbox deletion.
  • Eligible deferred rebuilds preserve their Deferred status while bypassing only the pending physical-validation requirement.

Second-opinion terminology and E2E selections are advisory. Live E2E does not run automatically for pull requests.

3 semantic terminology decisions

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

• established — explicit preview intent at docs/inference/set-up-vllm.mdx:374: Keep `explicit preview intent` for the recorded-route admission condition.
• established — recorded route at docs/inference/set-up-vllm.mdx:374: Keep `recorded route` while listing the additional metadata required for N1x rebuild admission.
• justified — canonical local endpoint at docs/inference/set-up-vllm.mdx:380: Keep `canonical local endpoint` because it distinguishes the accepted endpoint from rejected endpoint values.

E2E guidance

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

Recommended E2E: managed-image-protected-runtime

Security review: PASS

Reviewed revision a3237565f3b7860d4718dc6bb892da2a3e04c594.

• Authentication and authorization: PASS — no user identity, permission, or credential authority changes.
• Injection and command execution: PASS — the new decision is a pure comparison over validated registry and rebuild-selection fields; it does not construct commands or evaluate untrusted text.
• Secrets and privacy: PASS — the stored receipt is parsed through the existing typed receipt parser, and no credential value or new sensitive data is logged.
• Data integrity and lifecycle: PASS — the Deferred N1x exception is admitted only when recorded provider, model, endpoint, source, Docker driver, replacement selection, and any present receipt agree. Every mismatch and parse failure remains fail closed before sandbox deletion.
• Input and path validation: PASS — only the canonical host.openshell.internal:8000 vLLM route and exact N1x model are accepted; noncanonical endpoints, other services, conflicting models, other drivers, and unresolved replacement endpoints are rejected.
• Dependencies and supply chain: PASS — no dependency or external artifact changes.
• Concurrency and availability: PASS — the change carries an immutable boolean decision through existing preflight stages and adds no asynchronous work or unbounded retry.
• Observability and failure handling: PASS — malformed receipts return ineligible rather than throwing, and the ordinary readiness finding remains visible and blocking when the exception is not proven.
• Platform and deployment: PASS — admission still requires live N1x identity and waives only the pending physical-validation finding. Explicit false during authoritative rebuild preflight prevents ambient provider state from admitting a mismatched recorded route.

The focused fail-closed matrix covers route, source, driver, receipt, provider, model, and replacement conflicts. Required managed-image and runtime activation jobs passed; the remaining CodeQL and coverage-upload failures were GitHub HTTP 503 responses and are being rerun. No security blocker remains.

[prekshivyas]

Reviewed exact head a323756. The recorded-route eligibility predicate is fail-closed and scoped to the exact N1x managed-vLLM route; malformed/conflicting receipts and any provider, model, endpoint, source, driver, or replacement-selection mismatch remain blocked before deletion. The explicit false handoff correctly prevents ambient NEMOCLAW_PROVIDER from crossing the rebuild boundary. The CodeRabbit domain-layer request is addressed and its thread is resolved; security review passed. Local build and all six changed focused suites pass (88 tests). No blocking correctness, security, or trust-boundary findings.
