The env should be inferred from the VID map in `mcp-server/run-tests.sh` (nrf52 → rak4631, esp32s3 → heltec-v3) unless `MESHTASTIC_MCP_ENV*<ROLE>` is set.

Keep it scannable. If a field is missing or abnormal (no pubkey for a known peer, region=UNSET, num_nodes inconsistent with the hub, device on non-PPPS hub), flag it inline with a short `⚠︎ <one-line reason>`.

6. **Cross-device correlation** (only when >1 device is inspected):

7. **Recorder slice (cheap, always available).** The mcp-server runs an autouse log recorder that's been collecting from every connected device. Pull two short slices to surface anything weird that's already happened:

- `mcp__meshtastic__logs_window(start="-2m", level="WARN|ERROR|CRIT", max_lines=20)` — recent firmware errors. If empty, say "no recent errors"; don't manufacture concern.

|
||||
- If `recorder_status` shows `running:false` or `files.telemetry.last_ts` is null, note "recorder has no telemetry yet — enable `set_debug_log_api(True)` to populate" and skip this step gracefully.
