[Ubuntu 24.04][CLI&UX] nemoclaw <name> sessions export includes onboard warmup session — fresh sandbox appears to have 1 conversation instead of 0 #5511

Description

nemoclaw onboard automatically sends a "ping" message to the agent to verify the inference endpoint. This creates a session file (nemoclaw-onboard-warmup-<id>) inside the sandbox. When the user runs nemoclaw <name> sessions export on a freshly onboarded sandbox before having any real conversations, the export includes this warmup session and reports "1 session(s) exported". The user sees a conversation file they never created. A freshly onboarded sandbox should report 0 exportable sessions.

Environment

Device:        NVIDIA 2u2g-gen-0642 (RTX PRO 6000 Blackwell Server Edition)
OS:            Ubuntu 24.04.4 LTS
Architecture:  x86_64
Node.js:       v22.22.3
npm:           10.9.8
Docker:        29.4.3, build 055a478
OpenShell CLI: 0.0.44
NemoClaw:      v0.0.65
OpenClaw:      v2026.5.27

Steps to Reproduce

1. Install NemoClaw v0.0.65 and onboard a brand new sandbox without running any agent prompts:

   curl -fsSL https://www.nvidia.com/nemoclaw.sh | NEMOCLAW_INSTALL_TAG=v0.0.65 bash

   (sandbox name: empty-test)

2. Confirm no user sessions exist:

   nemoclaw empty-test sessions list

3. Run sessions export from a clean working directory:

   mkdir -p /tmp/empty-export && cd /tmp/empty-export
   nemoclaw empty-test sessions export

4. Observe the export message and the exported file.

5. Inspect the exported session file content.

Expected Result

Step 2: Sessions listed: 0 (no user conversations yet).

Step 3: Command exits with a friendly "nothing to export" message. No export folder is created.

Steps 4–5: The onboard warmup session (nemoclaw-onboard-warmup-*) is not visible to the user — it is an internal system session, not a user conversation.

Actual Result

Step 2: Sessions listed: 1 — the warmup session appears as a regular session:

direct  agent:main:expli...598124  1m ago  nemotron-3-super-120b-a12b  id:nemoclaw-onboard-warmup-969-1781598124

Steps 3–4: Export succeeds, reports Exported all sessions for agent 'main' (1 session(s)) and downloads the warmup session file.

Step 5: The exported file contains a single user message with content "ping" — sent automatically by the installer to verify the inference endpoint, not by the user:

{"type":"message","role":"user","content":[{"type":"text","text":"ping"}],...}

The warmup session is indistinguishable from a real user session in both the sessions list and the export output. A user who runs sessions export before their first real conversation will receive a confusing file they did not create.
