## Bug
Path Inspector "Show on Map" only rendered the first node of a candidate
path. Multi-hop candidates appeared as a single dot instead of a
polyline.
## Root cause
`public/path-inspector.js:186-188` and `public/map.js:574` (cross-page
handler) called:
```js
drawPacketRoute(candidate.path.slice(1), candidate.path[0]);
```
But `drawPacketRoute(hopKeys, origin)` (`public/map.js:390`) expects
`origin` to be an **object** with `pubkey`/`lat`/`lon`/`name` properties
— not a bare string. The code at lines 451-460 does `origin.lat` /
`origin.pubkey` lookups; with a string, both branches fail, `originPos`
stays null, and the originating node never gets prepended to
`positions`.
Combined with `slice(1)` stripping the head, the resulting polyline was
missing the first hop AND the origin marker — and short paths could
collapse to a single resolved node.
## Fix
Pass the full path as `hopKeys` and `null` as origin. `drawPacketRoute`
already iterates `hopKeys`, resolves each against `nodes[]`, and draws a
marker for every resolved hop. The "origin" arg was meant for cases
where the originator is a separate object (e.g., from packet detail with
sender metadata), not for paths where the origin IS the first hop.
```js
drawPacketRoute(candidate.path, null);
```
Two call sites fixed: in-page direct call (`path-inspector.js:188`) and
cross-page handler (`map.js:574`).
## Verification
**Code reading only.** I did NOT manually load the page or visually
verify the polyline renders. Reviewer should:
1. Open Path Inspector, query a multi-prefix path with ≥3 known hops
2. Click "Show on Map"
3. Confirm polyline draws through every resolved node, not just the
first
`drawPacketRoute` is hard to unit-test without a real Leaflet map, so no
automated test added.
