twislaandClaude Opus 5.5 b041c7b67c VPN: a WireGuard tunnel (#8)
CI / build (pull_request) Successful in 2m58s
Site / build (pull_request) Successful in 13s
The device joins a WireGuard network over whatever Wi-Fi it is on: one
peer, IPv4. A client's .conf is imported from the card (/vpn/wg0.conf) and
kept in the device's settings, private key included, never shown; Settings
offers to delete the file. A switch brings the tunnel up until the next
restart, "Start with Wi-Fi" every time; it waits for the clock, which a
handshake needs. VPN shows in the Status Bar.

The protocol is esphome/wireguard 0.4.8. It calls lwIP without lwIP's lock,
which this framework checks: every call into it is made with the lock held.

What goes through the tunnel is everything (AllowedIPs 0.0.0.0/0) or the
one subnet the device's tunnel address is in: lwIP routes by an
interface's subnet or by default, nothing finer. The import says how many
ranges it can't reach.

twislaandClaude Opus 5.5 3863d28593 Shell: the console's commands on the device's own screen and keyboard (#67)
CI / build (pull_request) Successful in 1m48s
Site / build (pull_request) Successful in 9s
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.

twislaandClaude Opus 5.5 34e6714785 Keys: one table file for the device's help panel and the website's key tables (#72)
CI / build (pull_request) Successful in 7m14s
Site / build (pull_request) Successful in 8s
Every screen's keys are constant tables in lib/core/src/app_keys.h (52 of
them, each under an `// id: Title` comment). An App's help() picks the table
of the state it is in. site/tools/gen_dev_docs.py reads the same file and
writes site/data/keys.toml; the `keys` shortcode shows a screen's tables on
its guide page, and /guide/keys/ shows all of them.

The Site job fails when the data file is out of date or a page asks for a
table that doesn't exist, and now also runs when app_keys.h changes. A key
added to an App shows up on the website without anyone editing a page.
