The gateway previously joined the relay room before opening the Linux
AF_PACKET socket. If the operator passed the wrong interface, a wireless
interface, or an interface that could not be opened, the relay could briefly
advertise a gateway that was never able to bridge LAN traffic.
Parse CLI args first, then keep platform handling in a small cfg-gated run
function. On Linux, build the config, open the AF_PACKET socket, and only then
join the relay as the room gateway. On non-Linux targets, fail before reading
relay certificate files, resolving relay names, or opening network connections.
Update the README and MVP test guide so the documented gateway startup order
matches the binary output.
Test Plan:
- cargo fmt --check
- cargo test -p lanparty-gateway
- cargo test --workspace
- cargo clippy --workspace --all-targets -- -D warnings
- git diff --check

Add a --list-tap-adapters mode to the Windows client. The command prints the
TAP-Windows6 adapter instance ids and exits without requiring relay, room, or
certificate arguments.
This makes the manual MVP test smoother on machines with multiple TAP adapters:
the operator can ask the binary for the exact ids, then rerun with
--tap-instance-id instead of relying on a separate PowerShell query or waiting
for the ambiguous-adapter startup error.
Test Plan:
- cargo fmt --check
- cargo test -p lanparty-client-win
- cargo test --workspace
- cargo clippy --workspace --all-targets -- -D warnings
- git diff --check
Refs: PLAN.md Windows client TAP adapter responsibility
Add a Windows client --tap-instance-id option for selecting a specific
TAP-Windows6 adapter by NetCfgInstanceId / InterfaceGuid. The client still opens
the only installed TAP adapter automatically, but now refuses to choose an
arbitrary adapter when multiple TAP-Windows6 adapters are present.
This keeps the MVP test run from silently configuring and opening the wrong TAP
adapter on machines that already have VPN or test TAP devices installed. The
error lists available adapter instance ids so the operator can rerun with the
intended value.
Test Plan:
- cargo fmt --check
- cargo test -p lanparty-client-win
- cargo test --workspace
- cargo clippy --workspace --all-targets -- -D warnings
- git diff --check

Add a dedicated manual test guide for the MVP proof. The guide keeps the
operator flow concrete: relay startup, certificate handoff, Linux gateway
startup, elevated Windows client startup, expected log signals, acceptance
checks, troubleshooting, cleanup, and the information to report back.
This is intentionally scoped to the manual MVP. It documents that installer,
GUI, production certificates, authentication, and end-to-end payload encryption
are outside this proof.
Test Plan:
- git diff --check
- reviewed TESTING.md for command flow and expected log signals
