Outcome

Onboarding now validates the bundled nvidia/nemotron-3-super-120b-a12b NVIDIA Endpoints model with the request parameters required by that endpoint.

Reason

The generic Chat Completions probe omitted the model's sampling and chat-template parameters, so endpoint validation could return HTTP 404 even though the selected model and route were correct.

Related issues

Fixes #10880

Changes

  • Match the exact bundled Nemotron 3 Super model identifier in the existing Chat Completions probe builder.
  • Send temperature: 1, top_p: 0.95, and chat_template_kwargs.enable_thinking: false while retaining the bounded 16-token probe.
  • Extend the existing onboarding probe test with the required request shape.

Verification

  • npx vitest run --project cli src/lib/inference/onboard-probes.test.ts src/lib/inference/health.test.ts — 2 files passed; 105 tests passed and 1 skipped.
  • npm run test:changed — 5 files passed; 209 tests passed and 1 skipped.
  • npm run build:cli — passed.
  • npm run typecheck:cli — passed.
  • npx vitest run --project cli src/lib/inference/onboard-probes.test.ts — 50 passed and 1 skipped after the review repair and main integration.
  • npm run validate:pr — passed against main at c811ef9bed6f7eb2b98dc7a98ff8e21da109598a.
  • Normal pre-commit, commit-msg, and pre-push hooks — passed.
  • gitleaks in the normal commit hooks — passed; the diff contains no secrets, API keys, or credentials.

Summary by CodeRabbit

  • Bug Fixes
    • Updated NVIDIA Nemotron 3 Super 120B requests with the required generation settings, including temperature: 1 and top_p: 0.95.
    • Disabled thinking mode for this model to ensure compatibility with NVIDIA endpoints.
    • Improved request payload handling for NVIDIA-managed endpoints while preserving standard behavior for compatible providers.
    • Ensured onboarding, validation, and health checks use the correct NVIDIA-specific request format.

Apply the sampling and chat-template parameters required by the bundled
Nemotron 3 Super endpoint during validation.

📝 Walkthrough

Walkthrough

NVIDIA provider selection now enables a Nemotron-specific Chat Completions payload. Onboarding, validation, and health probes propagate this option. Tests verify NVIDIA request fields and retain generic payload behavior for other compatible endpoints.

Changes

Nemotron NVIDIA probe support

Layer / File(s) Summary
Payload selection contract
src/lib/inference/openai-probe-models.ts, src/lib/inference/openai-validation-session.ts
The payload builder accepts useNvidiaEndpointProbePayload. When enabled for Nemotron 3 Super, it adds the required sampling and disabled-thinking fields.
Onboarding validation propagation
src/lib/onboard/inference-selection-validation.ts, src/lib/onboard/setup-nim-selection.ts, src/lib/inference/onboard-probes.ts, src/lib/inference/openai-validation-session.ts, src/lib/inference/onboard-probes.test.ts, src/lib/onboard/setup-nim-selection.test.ts, src/lib/inference/openai-validation-session.test.ts
NVIDIA selections enable the option. Probe execution and retries preserve it. Tests verify the serialized payload, successful validation, and generic behavior for other compatible endpoints.
Health probe integration
src/lib/inference/health.ts, src/lib/inference/health.test.ts
NVIDIA-managed health probes enable the specialized payload. OpenAI and Gemini retain the default payload. Tests verify the NVIDIA request parameters.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 04893

NVIDIA onboarding can report a cached generic validation as successful without sending the required Nemotron payload, allowing the original endpoint-validation failure to remain hidden. The cache key must distinguish payload variants before merge.

Exact-head review of 4a6693cde7cb5e160a8574999e89fe36a2e6e0ba.

P0

  • None.

P1

  • None.

The model-specific payload is limited to nvidia/nemotron-3-super-120b-a12b and is exercised through the serialized curl boundary; I found no security, product-scope, or trust-boundary regression. All six commits are GitHub Verified.

I am not approving this SHA: the branch is behind current main, the trusted gate reports changes skipped and test-e2e-sandbox failed, and the sandbox failure is inherited from base behavior that current main has already removed. Refresh from main, then let required CI and automated reviews settle on the new SHA.

Reviewed exact head f21a656. The NVIDIA/Nemotron payload is provider- and model-scoped, generic behavior is preserved, and direct request plus final build revalidation regressions cover the reported failure. No blocking findings.

Re-approved at exact head 088bdc3. The only delta since the prior reviewed head is a GitHub-verified, conflict-free merge of main (empty remerge diff), with no manual conflict resolution and no change to this PR's NVIDIA/Nemotron endpoint scope. Exact-head DCO, title, hashes, SDK packaging, growth, docs parity, and completed CodeQL quality checks are green; squash auto-merge remains appropriate once required checks settle. Infrastructure-only failures remain non-blocking review signals.

## Outcome

Adds the canonical dated documentation entry for v0.0.120 and records
the release's material user-facing changes before tag planning. The
Hermes rebuild guide now also documents the fail-closed immutable-base
requirement for legacy sandboxes without an image hint.

## Reason

Release planning requires a merged `docs/changelog/2026-09-04.mdx`
containing exactly one `## v0.0.120` heading. The existing automation
draft does not contain that required changelog and does not cover the
full release scope, so this PR provides a fresh, independently reviewed
release-docs update.

### Related issues

Relates to #10919

## Changes

- Add three release-note lead paragraphs and detailed, user-facing
v0.0.120 changes with canonical documentation routes.
- Cover configuration export and doctor (#11015, #11012); Hermes
runtime, recovery, and Discord policy (#10595, #11071, #11024, #10927,
#10983, #10988, #10999, #11019, #10682); Shields retirement (#10722,
#10996); OpenShell forwarding and runtime authority (#10695, #10814,
#10815, #10810); onboarding and recovery (#10690, #10900, #11046,
#10882, #10864); inference behavior (#10956, #10910, #11070); Deep
Agents MCP projection safety (#10911, #10909); and provider-profile
validation (#10884, #10895).
- Scope the legacy Hermes immutable-base rebuild guidance to the
Hermes-rendered recovery page.

## Verification

- `npx vitest run --project integration
test/generation/check-docs-links.test.ts
test/generation/check-docs-published-routes.test.ts
test/generation/post-merge-docs.test.ts` — 3 files and 125 tests passed.
- `npm run docs` — passed with 0 errors and 5 existing Fern warnings.
- Independent documentation audit — reconciled all 71 commits in
`v0.0.119..origin/main`, validated all 29 PR links and published routes,
and found no unsupported product claims or remaining corrections.
- Normal `pre-commit`, `commit-msg`, and `pre-push` hooks — passed.
- `git diff --check` — passed.
- GitHub commit verification —
`a22fe0989fd72c7daaa9b2e7a4734a3edc069aba` is Verified with reason
`valid`.
- Secret review — the diff contains no secrets, API keys, or
credentials.

## Review notes

The existing automation draft #10919 is intentionally left untouched.
This PR supersedes its release-docs content with the complete canonical
changelog and a variant-correct Hermes recovery update.
