Description

When onboarding NemoClaw with the Model Router provider, the model-router-venv virtual environment is created and contains python3, but the expected .fingerprint file is not created, breaking the intended venv version tracking and rebuild detection.

Environment

OS:           macOS
Architecture: arm64 (assumed for recent MacBook Pro; adjust if x86_64)
Node.js:      v22.22.3
npm:          10.9.8
Docker:       Docker version 29.2.1, build a5c7197
OpenShell CLI: openshell 0.0.44
NemoClaw:     nemoclaw v0.0.55
OpenClaw:     OpenClaw 2026.5.22 (a374c3a)

Steps to Reproduce

Pre-conditions:

• NemoClaw CLI installed (v0.0.37+; tested with v0.0.54).
• Docker running.

Steps:

1. Verify install.sh does not set up Model Router:

   grep -c "model-router\|pip3.*install" ~/.nemoclaw/source/scripts/install.sh

2. Run NemoClaw onboard and select Model Router as the provider (if available):

   nemoclaw onboard --fresh --name model-router-test

3. Walk through provider/model selection.
4. When prompted for provider, choose Model Router (if present in the menu).
5. Complete the rest of the onboarding flow.
6. Confirm the Model Router virtual environment exists:

   ls ~/.nemoclaw/model-router-venv/bin/python3

7. Check for the fingerprint file in the Model Router venv:

   cat ~/.nemoclaw/model-router-venv/.fingerprint

Expected Result

• grep in step 1 returns 0 matches, confirming install.sh does not pre-setup Model Router or run pip3 for it (Model Router venv should be created during onboard).
• nemoclaw onboard completes successfully, and selecting Model Router creates a model-router-venv under ~/.nemoclaw.
• The file ~/.nemoclaw/model-router-venv/bin/python3 exists, indicating the venv is populated.
• The file ~/.nemoclaw/model-router-venv/.fingerprint exists and contains a version fingerprint to track the venv's build, enabling NemoClaw to detect when the venv is stale and trigger a rebuild.

Actual Result

Steps and outputs from an actual run on macOS:

Checking for python3 inside the Model Router venv:

$ ls ~/.nemoclaw/model-router-venv/bin/python3
/Users/pshevate/.nemoclaw/model-router-venv/bin/python3

Attempting to read .fingerprint inside the Model Router venv:

$ cat ~/.nemoclaw/model-router-venv/.fingerprint
cat: /Users/pshevate/.nemoclaw/model-router-venv/.fingerprint: No such file or directory

The Model Router venv and python3 binary are present, but the .fingerprint file is missing, so there is no version-tracking metadata for the Model Router venv, contrary to the test's Expected criteria.
