network Git calls do not accept a work tree, alternate index

Error message

network Git calls do not accept a work tree, alternate index, or stdin

What it means

API-misuse guard in Git network_output: a network plumbing call (fetch/push/ls-remote) was constructed with a work tree, alternate index, or stdin redirection, which the network-call API forbids — network commands must run with the user's normal git configuration and environment. This is an internal contract check, not a user-input error.

Solutions

1. Fix the call site to use the plain network call API without work tree/index/stdin overrides
2. Use the non-network plumbing API for local operations that need those options
3. Add/adjust the debug output to identify the offending PlumbingCall
