Description

Summary:
When NEMOCLAW_PROXY_HOST and NEMOCLAW_PROXY_PORT are exported in the host shell before reinstalling NemoClaw, the resulting sandbox still uses the default proxy http://10.200.0.1:3128 instead of the configured custom proxy. This causes proxy override validation to fail.

Environment:

• Platform: macOS 26.1
• Hardware: Apple M4, 24 GB
• Runtime: Colima
• Docker ServerVersion: 29.2.1
• NemoClaw: v0.0.4
• Install path: pure release-style install from ~
• Shell: zsh

Repro steps:

1. In the same host shell, export custom proxy variables:

`export NEMOCLAW_PROXY_HOST=1.2.3.4`
`export NEMOCLAW_PROXY_PORT=9999`

2. Uninstall NemoClaw in the same shell:

`nemoclaw uninstall --yes`

3. Reinstall NemoClaw in the same shell:

`curl -fsSL https://www.nvidia.com/nemoclaw.sh | bash`

4. Complete onboarding with a new sandbox, e.g. proxy-test

5. Reload shell:
   source ~/.zshrc

6. Connect to the sandbox:
   nemoclaw proxy-test connect

7. Inside sandbox, check proxy envs:
   echo $HTTP_PROXY
echo $HTTPS_PROXY
echo $NO_PROXY
echo $no_proxy

Actual result:
Inside sandbox, the proxy envs still use defaults:

• HTTP_PROXY=http://10.200.0.1:3128
• HTTPS_PROXY=http://10.200.0.1:3128
• NO_PROXY=localhost,127.0.0.1,::1,10.200.0.1
• no_proxy=localhost,127.0.0.1,::1,10.200.0.1

Expected result:

• HTTP_PROXY and HTTPS_PROXY should reflect the custom values derived from:
• NEMOCLAW_PROXY_HOST=1.2.3.4
• NEMOCLAW_PROXY_PORT=9999
• Default proxy values should not be used
• NO_PROXY and no_proxy should still match
• inference.local should remain absent from NO_PROXY

Notes:

• This is not a shell persistence issue; the custom env vars were exported and preserved in the same terminal through uninstall and reinstall.
• Partial expected behavior is still correct:
• NO_PROXY and no_proxy match
• inference.local is absent
• The failure is specifically that custom proxy host/port are ignored.
