Outcome

Hermes Portable restores its receipt-scoped forwards before opening an interactive session, and managed auxiliary requests retain their explicit output-token limits instead of occupying the inference slot until a large default budget is exhausted.

Reason

Portable stop/start/recreate validation exposed two remaining failures after the lifecycle-lock repairs merged:

  • interactive launch could continue before the Hermes forwards required by the TUI were restored;
  • Hermes v0.20.6 removes max_tokens from auxiliary requests to custom endpoints, which also removed NemoClaw's small session-title limit on inference.local and made generation appear to hang.

PR #11427 independently delivered the other two branch fixes discovered during the same validation: exact Hermes dashboard/API forward reuse and skipping OpenClaw state initialization for Hermes. This PR intentionally excludes those superseded local implementations.

Changes

  • Requalify the active Hermes Portable lifecycle authority and restore receipt-scoped forwards before interactive session startup.
  • Patch Hermes' auxiliary request construction at image build time so explicit limits are preserved only for NemoClaw managed inference.local.
  • Integrity-pin the patcher and updated image-build probes.
  • Prove that managed requests retain the 64-token title-generation limit while unrelated custom endpoints keep upstream Hermes behavior.

Local environment note

The build-context authority suite rejects this seat checkout because its source directories are group-writable. That is an expected fail-closed environmental result, not a product assertion failure. GitHub CI must provide the isolated broad result. hadolint is not installed on this seat and remains a CI requirement.

No secrets, API keys, or credentials are included.

Summary by CodeRabbit

  • Bug Fixes

    • Hermes auxiliary inference requests now preserve token limits for managed inference routes and external MoA reference requests, while omitting them for external title-generation requests.
    • Interactive Hermes Portable setup now verifies lifecycle authority and restores connection forwarding before completing.
  • Quality Improvements

    • Added build-time validation and automated coverage for token-limit handling, patch safety, and connection forwarding.
    • Verified packaged Hermes images contain the expected changes and exclude temporary patching tools.

📝 Walkthrough

Walkthrough

The PR adds a verified Hermes auxiliary-token patch and image-build probes. It also restores Hermes forwards before interactive Portable connections and adds focused tests for both behaviors.

Changes

Hermes auxiliary token limits

Layer / File(s) Summary
Auxiliary token patcher behavior
agents/hermes/patch-auxiliary-token-limit.py, test/agents/hermes/hermes-auxiliary-token-limit.test.ts
The patcher preserves managed token limits, supports idempotent execution, and rejects unexpected source layouts.
Image build patch integration
agents/hermes/Dockerfile, src/lib/onboard/experimental/hermes-portable-build-context-files.ts, src/lib/onboard/experimental/hermes-portable-build-context.ts, src/lib/onboard/managed-startup/profile.ts
The image build verifies, applies, compiles, probes, and removes the patcher. Build-context manifests and integrity inputs include the patcher.
Auxiliary request probe validation
agents/hermes/image-build-probes.py, test/agents/hermes/hermes-image-build-probes.test.ts
The probe checks token limits for managed inference, title generation, and external MoA-reference requests. The test suite includes the probe command.

Hermes forward recovery

Layer / File(s) Summary
Interactive forward restoration
src/lib/actions/sandbox/connect.ts, src/lib/actions/sandbox/connect-flow.test.ts, test/support/connect-flow-test-harness.ts
Hermes Portable setup restores forwards after route verification and checks forward health before session startup. The test harness and connect-flow test cover the recovery sequence.

Blocking: latest PR commit 9c88815 adds a separate RUN layer in agents/hermes/Dockerfile for the auxiliary-token patch. The required PR build and direct managed startup (Hermes) job built a 125-layer image and failed the exact image contract because Docker import allows at most 124 layers. This is attributable to the PR and makes the supported Hermes managed image unusable. Fold the patch hash check, application, compile, probe, and cleanup into an existing adjacent RUN instruction, or otherwise remove a layer without weakening those checks, then rerun the exact managed-image job.

CodeRabbit already filed two valid non-blocking coverage suggestions: assert restored forward health at the public boundary and exercise the external moa_reference token-limit path. Security review: PASS for secrets, access control, injection, supply-chain integrity, configuration, resource limits, data handling, concurrency and lifecycle state, and security-relevant coverage.

@rsliter Addressed the blocking layer-count review in 80ad166. The auxiliary patch now shares an existing adjacent RUN layer while retaining its hash check, patch application, compile check, in-image probe, and cleanup. The exact PR managed-image contract and direct Hermes startup job now pass: https://github.com/NVIDIA/NemoClaw/actions/runs/34628397648/job/103360156374. Both CodeRabbit coverage suggestions are also implemented and their threads are resolved. Please re-review.

Re-reviewed latest PR commit 80ad166 against base commit 70cfff5. The previous Docker layer-count blocker is resolved. The auxiliary-token patch now shares existing RUN layers while retaining its integrity check, patch application, compile check, in-image probe, and cleanup. The required Hermes managed-image and direct-startup checks pass.\n\nThe added tests verify required port-forward health before interactive session startup and preserve the external moa_reference output limit. CodeRabbit confirmed both findings are resolved and reported no new actionable comments. Security review remains PASS for all nine categories. No blocking defect remains.
