The MeshCore preset is the default for a new device, in the Settings and
in the radio before the Scanner is opened. The setting now accepts it:
it only took the 7 Meshtastic presets, so MeshCore picked in the App was
not saved.
Messages on MeshCore's public channel are decrypted with the channel's
published key (AES-128, checked with 2 bytes of HMAC-SHA256): the row
shows who says they sent it and the start of the text, the details the
sender, the time and the whole text. Other channels and private messages
stay encrypted.

- MeshCore joins the presets (EU/UK Narrow: 869.618 MHz, 62.5 kHz, SF8,
CR 4/8, sync 0x12), after the Meshtastic ones so stored choices keep
their number; `lora preset MeshCore` on the console
- lib/meshcore reads what MeshCore sends in clear: header, path, and a
node's advert (name, kind, key, position)
- the list row, the details, a Capture's viewer and the console echo read
a packet by the sync word it was received on
- the bandwidth is printed as 62.5, not 62

- uname in the console and /uname in IRC: the firmware, its version and the chip
- scp: one file between the card and a trusted server, over SSH, with the
device's key or a password asked (masked) in the Shell
- shared libssh helpers in src/platform/libssh_util
- README, user guide, command reference and a how-to updated

The SSH App opens one session to a shell, over libssh (LibSSH-ESP32 5.10.0)
on mbedTLS. A server is trusted the first time on its fingerprint, and a
changed key is a warning with Cancel selected. The password is typed each
time and kept nowhere; or the device makes itself an Ed25519 key, whose
public half is shown, written to /ssh/id_ed25519.pub and printed by
`ssh status`.
lib/term is the terminal: what a shell, less, top, nano and vim send, with
sixteen colours, scroll regions, the alternate screen and 100 lines of
scrollback. Five text sizes with Ctrl and + or -, from 60x20 to 26x8, told
to the far end. The session goes on when the App is left; SSH shows in the
Status Bar. `ssh user@host` in the Shell opens the App.
Also:
- Keys that aren't characters carry Shift, Ctrl and Alt. The terminal needs
it, and it makes Ctrl+Fn+up/down in a note and Shift+Tab in Gemini work
from the real keyboard.
- IRC doesn't try to connect under 60 KB free: started with a session open,
its TLS handshake took the heap down to 236 bytes.
- libssh's own curve25519 is left out of the build (scripts/libssh_filter.py):
libsodium's has the same names.
Costs 292 KB of flash and about 50 KB of heap while a session is open; not
started under 75 KB free.
Docs: guide page, how-to, FAQ, home page, Status Bar, SD card folders, the
memory how-to, README, glossary, N1 notes with Q254 to Q266 and the checks.

The rest of the issue's list. tls makes a handshake that checks nothing,
then says the certificate in words: who it is for, who signed it, until
when, and whether this device's roots and the name asked for accept it,
with the reason when they don't. ntp compares a time server's clock with
the device's. netstat lists what listens and what is connected.

Network troubleshooting from the device itself, in the Shell and over both
consoles. ping, nslookup, port and traceroute each run on a task of their
own and print as they go, to the console that asked; one at a time, and
`cancel` stops it. ifconfig and arp answer at once: the interfaces (Wi-Fi
and the VPN), which is the default route, the DNS servers, the neighbours.
nslookup asks a DNS server itself, so it can say which server answered and
in how long, and ask another. A sized ping finds what a tunnel really
carries.
With a how-to, "When the network doesn't work", and the rest of the docs.
tls, ntp and netstat from the issue's list are not in this.

The documentation had kept up feature page by feature page and nowhere
else. Now also:
- the home page's App cards (notes of any size, pictures, sharing) and its
note (the Shell, the VPN, the screenshot key);
- the guide: VPN in the Status Bar and in Settings, the three keys that work
everywhere, screenshots of the Shell, a picture, sharing, the VPN page and
the help panel;
- three how-tos: move files with your phone, set up the VPN, take a
screenshot; where the files are and what things cost in memory;
- the FAQ: screenshots, and what listens on the network;
- the README's opening: what the firmware does today;
- the glossary: Tunnel, Sharing, Screenshot;
- every milestone's status line, with the version each thing shipped in.

An App in the Launcher that runs the same commands as USB serial and the
Debug Console, trusted like the first. It shows what the console prints
while it is open, through a second ring of the console's that exists only
meanwhile; Ctrl+b keeps only what follows your own commands. Tab completes
a command's name from the firmware's help text, Fn with up and down recalls
earlier lines, Alt with up and down scrolls back. `rm` asks first in the
Shell, `rm -f` doesn't. Nothing is kept once the App is left.
`screenshot [seconds]` saves the screen as a PNG in /screenshots on the
card, now or after a pause: written a row at a time, indexed colour with
RGB332 as the palette, in one stored deflate block.
487 host tests (11 new: the PNG writer, the Shell's log filter, Tab).
Checked on the device over the Debug Console: commands, Tab, history, a
screenshot fetched and decoded on the PC, rm with and without the question,
a delayed screenshot of another screen. 12 KB of flash; 7 KB of heap while
open. Decisions Q204 to Q212 in docs/milestones/S1.md. Safe Mode: #77.

Eight how-to recipes and a FAQ page with a list of its questions, from the
README, the milestone documents and the Apps' source. The guide templates
become generic (the parent section gives the eyebrow, title and pager).
