# Peer Network Medium Card

## Symptom

The Nearby Macs card showed a connected peer but did not show whether the control path was Thunderbolt, Wi-Fi, or another interface.

## Root Cause

The backend already computed `networkPath` for both peers and display targets, and logs confirmed `dhiru-mac-pro.lan` was detected via `Thunderbolt bridge0`. The renderer only used `target.displayName`, display size, and placement in each peer card, so the network medium was only available in the footer status line.

## Fix

`app-ui/renderer.js` now renders a compact per-card path line using `target.networkPath`, and `app-ui/styles.css` styles that path as peer metadata.

## Evidence

Recent logs include:

```text
[2026-07-08T17:02:44.006Z] [HELLO] dhiru-mac-pro.lan 169.254.148.79 via Thunderbolt bridge0
```

Verification run:

```text
node --check app-ui/renderer.js
node --check app.js
git diff --check
```

All checks passed.
