What

The Sniffer shows a packet's clear header and a hex dump (M3, Q96). Once the protocol is decoded (#24), its details should show what's inside: the port, and the text, position or node info, for Channels whose key we have.

What's known

This was always the plan: the first design round said the Sniffer shows raw packets until the Meshtastic protocol exists, and decoding is added then.
lib/lora/src/packet_view.cpp builds the detail lines; decoded fields are more lines after the header.
A payload we can't decrypt (another Channel's key, a public-key Direct Message) says so instead of showing noise.
Captures stay as received, encrypted: Wireshark's own Meshtastic support, if any, is the reader's business.

Questions

Decoded text in the list row too, or only in the details?
A filter: only one Node, only one Channel, only text?
