scan_masscan_nmap() and scan_geo_scout() were running nmap serially — one host at a time with a 60s timeout, turning a 1h estimate into 24h+ for large scans. Both modes now use ThreadPoolExecutor with 10 workers (configurable via WEBRUNNER_NMAP_WORKERS env var). geo-scout uses an inner scan_one() helper to batch nmap + probe_service() per host within the same future. Also fixed probe_service() bytes format antipattern and removed dead targets_arg variable from scan_nmap_only(). run_scan.yml converted from command: > folded scalar to command: argv: list form to prevent argument splitting on space-containing values.
