Expand description
Lightweight, env-gated tracing for the networking paths (transport connect, fetch/push negotiation, pack transfer).
Set GRIT_NET_DEBUG=1 to print one-line [grit-net] … markers to stderr
before, during, and after each remote operation. Off by default and
essentially free when disabled (the gate is read once and the format args are
not evaluated). Embedders can consult enabled to interleave their own
before/after markers with the library’s.
