MQTT session state

Transport session, not data freshness: a gateway can hold a session while idle, and can show recent data moments after its session has dropped. Data freshness stays on the gateway panel above.

Reachability & firewall allowlist

Reachability is evaluated separately from health: a healthy-looking gateway whose carrier-NAT egress IP has rotated off the allowlist will fail its next reconnect. Sources are read-only; security-group state comes from a deploy-supplied snapshot.

LogFile inventory

Read-only inventory of Mars/gateway artefacts (GW_* workbooks, mpulog and .log files) under the data roots. Downloads are pattern-restricted, root-contained and size-capped; parsers and register attachment are later D4 steps.
