fix: GET /v1/scraper/jobs/ rows parameter silently returns 0 results on non-numeric input #1116

Problem

In GET /v1/scraper/jobs/, passing a non-numeric rows parameter silently returns 0 results:

rows=abc → (int)"abc" = 0 → min(0, 500) = 0 → Solr returns 0 docs

No error, no warning — just an empty data array.

Current code

 = isset($_GET['rows']) ? min((int)$_GET['rows'], 500) : 100;

Fix

$rowsRaw = isset($_GET['rows']) ? (int)$_GET['rows'] : 0;
$rows = ($rowsRaw > 0 && $rowsRaw <= 500) ? $rowsRaw : 100;

Impact

Low — the scraper never passes rows (uses default 100). Only affects manual testing or misbehaving clients.
