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.

It made 50,000 passes a second and kept core 1 100 % busy at rest. Keys
are buffered by the keyboard controller, the consoles and the radio have
their own tasks, and no Service ticks more often than every 50 ms, so
the loop now rests 5 ms after a pass with the screen on and 20 ms with
it off; never during a serial file transfer. Safe Mode's loop too.
Screen off: 50 passes a second and core 1 at 1 %; screen on: 167 and
10 %. The chip settles 4 C cooler (34.3 against 38.3). GNSS, Gemini, an
upload, the Sweep and the radio's interrupt all checked at the new pace.
`tasks` shows the loop's passes; Debug Builds: `loop spin on|off`.

Five views, Tab between them: Overview (each core's load, memory,
traffic, battery, two minutes of load), Tasks (share of a core over the
last second, lowest free stack, flagged under 512 bytes; `s` sorts),
Memory (free heap against the floors of Q86), Network (bytes per
service, and what's moving now), System (what `info` prints, plus
battery, card, radio, GNSS). It samples once a second and keeps history
only while open.
The arithmetic is host-tested, including the trap found on the device: a
task's run-time counter only moves when it's switched out, so the task
that samples (the main loop, alone on its core) gets what's left of its
core. `tasks` now samples across a second of normal running instead of
inside its own wait. The main loop uses 100 % of core 1 at rest (#40).

Enter on a Saved Network opens its page instead of asking to forget it:
"IP address" switches between Automatic and Fixed, with an address, a
prefix and an optional gateway. Fixed starts from what the network is
giving the device; the draft is checked and applied on leaving the page,
so a half-typed address is never used. "DNS and NTP" holds the two DNS
servers, "Always use my DNS" and the two NTP servers. Enter on Status
shows the connection's details and where each value came from. Address
fields take digits and dots only; refusals show as Toasts.
Checked on the device through the screens: Fixed 10.39.39.13 applied and
reverted to Automatic, a prefix of 99 refused. Measurements in
docs/milestones/S1.md.

The plan and decisions Q105 to Q116 (docs/milestones/S1.md). lib/net:
strict IPv4 parsing, prefix and mask, and the checks a Fixed setting must
pass, each refusal with its reason. A Saved Network is Automatic or Fixed
(address/prefix and an optional gateway), kept with it in flash. Settings:
two DNS servers (9.9.9.9, 1.1.1.1), "Always use my DNS", two NTP servers
(pool.ntp.org, time.cloudflare.com). Host-tested: 383 tests.
