Authorized network reconnaissance of "Northgate Freight Lines Ltd.". Scope is strictly limited to hosts 77.91.123.159 and 45.92.170.247 - do not touch anything else.

MISSION - RECONNAISSANCE ONLY (no exploitation, no credential use, no changes to systems):
1. Discover all open TCP ports on both hosts (full port scan with service/version detection).
2. Identify every running service and protocol with versions (HTTP, SSH, SMB, WinRM, DNS, Kerberos, LDAP, RDP, database, AV agents, scheduled services).
3. Identify host roles (domain controller, web server, OS versions, domain/workgroup, AD users/groups visible anonymously, SMB shares).
4. Identify security products and their state (antivirus services, real-time protection status, scheduled tasks).

Produce a structured recon report in findings.md: per host - open ports, services+versions, roles, shares, notable security findings. If a delegated task does not report back within ~10 minutes, do not idle waiting - proceed yourself with direct tool calls.
