Outcome

Managed dcode -n now returns a non-empty reply and exits 0 with NVIDIA Nemotron. JSON mode also returns a success envelope with a non-empty response and exit 0 instead of agent_failure after a successful provider round trip.

Reason

Deep Agents Code 0.1.55 sends an OpenAI-specific prompt_cache_key, and its native Nemotron policy nudge adds internal nemotron_ message names. NVIDIA Endpoints rejects both request shapes, causing the non-interactive command to fail without returning the generated reply.

Related issues

Changes

  • Disable prompt_cache_key in the managed Deep Agents Code patch because the managed NVIDIA endpoint is the current consumer and rejects that OpenAI-specific field. A direct CLI-only response change would not repair the rejected provider request; generated-package and live image checks protect the override.
  • Adapt the native Nemotron policy-nudge middleware at its existing slot for OpenAI aliases, preserving OpenRouter’s native behavior, so only copied provider-bound HumanMessage objects lose internal nemotron_ names. This preserves graph state and native middleware order; profile validation covers synchronous and asynchronous request paths.
  • Classify LangGraph RemoteException failures using the existing closed diagnostic vocabulary without exposing exception messages or provider content.
  • Refresh the profile source integrity pins and extend generated-runtime, profile, classification, and cloud E2E checks for the repaired request shape.

Verification

Current repair commit: 9e10cd1588a20bb51232a868b12d161a5362a36e.

  • Focused integration suites: 187 tests passed, 2 platform-specific tests skipped. This includes state preservation on sync/async requests, native OpenRouter nudge preservation, stale config-patch rejection, remote-error redaction, wheel installation, and codebase size checks. Python wheel tooling ran in an isolated virtual environment.
  • npm run build:cli and npm --prefix nemoclaw run build: passed.
  • NODE_OPTIONS=--max-old-space-size=5120 npm run typecheck:cli: passed.
  • NODE_OPTIONS=--max-old-space-size=5120 npm run validate:pr: passed against canonical base 74c628ef625177a0dc3a227accdc0379bfd1e252. The validation scripts, configurations, manifests, and lockfiles match that base; installed validator paths and digests were recorded.
  • The diff contains no secrets; the publication secret scan passed.

Original implementation evidence

  • npx vitest run --project integration test/cli/non-interactive-error-classification.test.ts test/agents/deepagents/langchain-deepagents-code-nemotron-profile-plugin.test.ts test/agents/deepagents/langchain-deepagents-code-direct-module-patch.test.ts test/agents/deepagents/langchain-deepagents-code-progressive-tool-disclosure.test.ts test/agents/deepagents/dcode-non-interactive-json.test.ts test/automation/pull-requests/growth-guardrails.test.ts — 6 files and 226 tests passed on 5a2adbb950e137a5ea16adabb1b5d03dbc6b0273.
  • Source-built live E2E on sandbox i10549-compat-yim, gateway nemoclaw-10557, and NVIDIA Nemotron — text mode exited 0 with a non-empty response; JSON mode exited 0 with status=success and a non-empty response.
  • npm run validate:pr — passed on the merged candidate.
  • env -u SSL_CERT_FILE npm test — 40,723 passed, 147 failed, and 95 skipped. The largest failure cluster, 29 corporate-CA Dockerfile fixture failures, reproduces identically on clean base de7f565dd062b6f5affe12218ad825c97efee042; the issue-focused suite and live image validation pass.
  • Secret review — the diff contains no secrets, API keys, or credentials.

Review notes

The follow-up resolves both actionable hosted Advisor findings from run 34316782327: preserve native OpenRouter requests and reject a stale config patch. It also resolves CodeRabbit's graph-state test gap across unit, installed-image, and deployed-sandbox probes. The CodeRabbit docstring suggestion does not require a behavior change.

Local Advisor failed before specialist execution: OpenShell reported sandbox is not ready and SSH exit 255. Sandbox deletion succeeded. The authorized alternative review covers the complete candidate diff, correctness, security boundaries, registration rollback/idempotence, regression evidence, and deterministic E2E selection. This is self-review supplemented by hosted reviews, not independent self-review or Advisor clearance. Current main was integrated to consume the merged local-Advisor bootstrap repair; no feature scope was added.

Original review evidence

agents/** is a contributor-sensitive path. Three fresh-context read-only reviews examined repository NVIDIA/NemoClaw, commit 5a2adbb950e137a5ea16adabb1b5d03dbc6b0273, and the complete origin/main...HEAD diff for correctness, security/privacy, validation, and maintainability. All reported no blockers. The final base-only merge produced commit 88edf925d7788bf53dee70eef81a576adb6364f0; the reviewed diff remained byte-identical at SHA-256 1d9ff49a2be9704defb4beba43cab4ba48e253d48dd8dfdbae195c295585e511. Advisory cleanup observations do not affect the request or authorization path. This PR awaits independent repository review.

Current candidate: 9e10cd1588a20bb51232a868b12d161a5362a36e.

CodeRabbit's current review reports no actionable findings and confirms the graph-state repair. The candidate remains unchanged while existing dependency fixes settle.

The managed-image workflow failed, so the selected manual E2E run has not been dispatched. Follow-up will consume the required merged dependencies, refresh validation and review evidence, and continue through successful image qualification and selected E2E. No check is waived and this is not a completed human-review handoff.

Refresh and validation update:

Manual E2E:

  • Head run: https://github.com/NVIDIA/NemoClaw/actions/runs/34628592131
  • Head SHA: 2790af1f02a5214fcbfdb79f20287472434c0331
  • Base SHA: 70cfff5f946a9bb31d1147f78ffbda914a2efaa2
  • Trusted workflow SHA: 95b2eee9c46e9a9c5655f5fc760bc7c3fa135742
  • Correlation ID: 075a9dd3-1f01-4a2c-88ab-3b5cfc9a88a6
  • Selectors: empty/default full suite; inference mode mock; staging and Jetson disabled.
  • Result: 70 jobs passed, 18 failed, 14 skipped. The candidate-relevant ubuntu-repo-cloud-langchain-deepagents-code hosted-inference job passed.
  • Failed jobs uploaded artifacts and ran cleanup. Inspected credential scans and cleanup showed no secret-leak evidence or required rotation.

The CI failure-classification skill is unavailable, so the failed head run ordinarily requires an identical-selector exact-base replay. That replay could not be validly dispatched: while the long head run executed, main advanced from workflow SHA 95b2eee9... to f267027b.... The trusted workflow requires both refs/heads/main and an input workflow SHA equal to the run workflow SHA, so the old workflow identity can no longer be replayed. Formal manual-E2E comparison outcome: unresolved (identity incomplete), not a candidate-regression finding.

Several head-run failures are independently consistent with base/runtime drift, and fixes landed on main during the run: #11215, #11554, and #11578. No failed manual job exercised the changed DCode response behavior; the DCode hosted-inference lane passed.

Shepherd refresh on fa69a1e

  • Merged current main e8071e8, including fix(test): let the host timeout own supervisor cleanup #11576.
  • Root cause of the prior CLI shard 8 failure: the launch-agent-turn supervisor fixture gave the session a 2-second budget while asserting the host-owned 2.5-second timeout. The session could finish first, so timedOut was false. fix(test): let the host timeout own supervisor cleanup #11576 raises that fixture budget to 10 seconds so the intended host timeout owns cleanup.
  • Exact regression file now passes: 6 passed, 38 skipped. Candidate-focused DCode validation passes: 153 passed, 2 skipped. npm run validate:pr passes on the clean signed candidate against canonical main.
  • The canonical local Advisor review remains unavailable: OpenShell returned sandbox is not ready and SSH exit 255 after allocation; cleanup succeeded. The effective patch ID is unchanged from the previously reviewed candidate (210f414b62d2c675ccaa655ff89cfd104d3eb6b1), and a fresh direct correctness/security review found no actionable issue.
  • GitHub verifies the new head signature. New-head CI and automated review are in progress.

External-gate follow-up for fa69a1e

  • CI / Pull Request is fully green; all 12 CLI shards passed, including former blocker shard 8 in 8m47s. CodeRabbit is green.
  • The managed-image workflow failed only in OpenClaw-only live gates after all candidate-relevant DCode image, staging QA, direct startup, and architecture checks passed. Both MCP discovery passes exhausted three Cloudflare Quick Tunnel attempts; cleanup and credential scans passed. The same two failures occurred concurrently on unrelated managed-image runs 34642384270, 34643362076, and 34643647403, establishing an external shared outage rather than a DCode regression.
  • The all-agent activation gate separately failed while the first OpenClaw sandbox entered Error before Ready. The fallback OpenShell deletion completed; no DCode agent was reached.
  • Focused E2E run 34645488694 was rejected by the trusted base-image resolver before candidate execution because the managed-image workflow must finish successfully. No candidate E2E resources or credentials were exercised.

The five-minute shepherd monitor remains active. I will publish the next current-main candidate and re-run the deterministic focused E2E only after these shared OpenClaw infrastructure gates recover; repository policy does not permit a blind broad rerun.

Reviewed exact head fa69a1e against the accepted #10549 regression scope. The current head addresses both prior Advisor findings: OpenRouter retains its native Nemotron nudge, while only OpenAI aliases repair copied provider-bound internal names; the managed patch idempotence path now requires the prompt-cache config override. Focused regression suites pass 153 tests with 2 expected skips on supported Python. Nine-category security review found no secret exposure, unbounded diagnostics, new authority, egress, command execution, path, sandbox, credential, or supply-chain defect. CodeRabbit reports no actionable finding. The remaining exact-head hosted failures are classified transient infrastructure failures and are being rerun.
