A release downloads straight into the inactive slot through the existing
install path: the signature is checked after 160 bytes, before anything
is written, the hash at the end. Tried on the device against the real
server: a download cut short, a flipped byte in the signature and one in
the image are each refused with the running firmware untouched; the real
v0.10.0 installed, restarted, and confirmed itself on Probation.
A TLS connection to Gitea peaks at about 52 KB of heap whether or not the
certificate is verified. With IRC connected (66 KB free) a check left 3 KB
and a download 836 bytes. A check, list or install a person asks for now
makes IRC step aside (holdForUpdate) and come back after: the lowest free
heap during a full download with IRC connected is 38 KB. The daily check
never interrupts IRC; with IRC up it waits. A TLS connection starts with
80 KB free (it was 55).
Debug Builds get test knobs: update probe <host>, update damage cut|flip,
update pretend <version>.

Debug Builds: `lora noise test` changes one thing at a time, Sweeps the
band, and reports the floor under each condition; it runs on the device
by itself, since one condition pauses Wi-Fi (not saved, so a restart
brings it back). Result, at 125 kHz: -117 dBm with the antenna switched
off, -106 with the GNSS receiver in standby, -98 with it running. The
receiver's serial line isn't it (one sentence a second changes nothing),
and neither are the main loop, the CPU frequency, Wi-Fi, the screen or
the radio's own regulator, all within 1 dB.
Settings > "Pause GNSS for LoRa", off by default: the receiver waits in
standby while the radio listens or sweeps, except during a Track, and
has a Fix again about 7 s after. The GNSS App says it's paused.
11 dB remain between the antenna with GNSS quiet and the chip alone,
untouched by anything that can be switched from the firmware.

The GNSS Service reads the receiver (UART 15/13, 115200, 1 KB buffer)
from its 50 ms tick and feeds the NMEA parser. With a Fix it sets the
clock (GNSS is the most trusted TimeSource) and refreshes it every 10
min. Settings gets GNSS On/Off and the coordinate format (Q64).
Off puts the receiver in standby with $PCAS12,65535, renewed hourly; On
wakes it with a hot start, $PCAS10,0. Both measured on the device: the
output stops within a second, and a command wakes it within a second.
Commands: gnss status (Fix, satellites per constellation, bytes and
sentences), gnss nmea on|off, gnss send <sentence>, gnss restart. The
probe is gone; never drive GPIO 15 (the receiver's output): the first
probe's swapped-pin attempt silenced it until a power cycle.

- lib/wifi (host-tested): SavedNetworks (up to 8, validated, hidden
flag, persisted) and WifiController (joins the strongest Saved
Network, tries hidden ones in turn, backoff 10/30/60 s, connect
timeout, Monitoring override, radio off without Saved Networks)
- WifiService carries out the controller's actions, sets the EU
country code, and syncs the Clock over SNTP without touching the TZ
- Wi-Fi On/Off setting; Settings > Wi-Fi page: status, add from a scan
or a hidden network, forget
- Status Bar: W + signal bars, W? while searching, MON while monitoring
- Serial: wifi add / wifi status (replaces the step 1 heap probe)
Verified on the device: joins the test network ~5 s after boot, clock
set over NTP, ~129 KB free heap while connected.

- lib/apps_model (host-tested): SettingsMenu (rows, readable values,
choices, validation messages) and SetupWizard (names, Region
confirmation, timezone; saves only when finished)
- AppManager: modal Apps that Home/Back can't leave (setup wizard)
- SettingsApp: all settings plus Storage (usage, erase SD behind a
dialog) and About (version, node id, battery, memory, uptime) pages,
replacing the temporary Diagnostics App
- SetupApp: first-boot wizard, opened modally until SetupDone
- Node id and default names derived from the MAC like Meshtastic
- Widget demo is now hidden (About, then w)
- lib_ldf_mode = deep+ so libraries see each other's headers
