custom_sdkconfig makes pioarduino regenerate the ESP-IDF libraries:
asymmetric TLS buffers (16 KB in, 4 KB out) and dynamic buffers that
free handshake-only data once connected. The rebuild also follows the
board: no PSRAM, 8 MB flash. The project now carries the partition
table the hybrid build needs (identical to the framework's: the app
slots must not move under updates over the air). Generated files are
ignored.
Debug Build, GNSS on, IRC on TLS: 78 KB free and a 59 KB low (M2 began
at 31 KB and 12.6 KB; the floor is 40 KB). The full stress set passes
on it: refused installs over Wi-Fi and from SD, put/get, screenshot,
core dump decode, Probation; under all of it at once, the low is 46 KB.

IrcService::disconnect() stops the session from any state: QUIT if
connected, then no more retries. /quit goes through it (before, it only
stopped a connected session; while waiting for Wi-Fi or retrying it did
nothing), and so does the new `irc stop` command. Stopped by hand,
opening the IRC App no longer reconnects; typing a line does.
mDNS is gone: it never crossed the dev box's routed network, and it
cost about 7.5 KB of RAM. Pushes go to the IP shown in Settings ->
Firmware, which drops its Name row. OTA Q54 records the change.
On the device, Debug Build: 105.6 KB free with Wi-Fi (was 98); with IRC
on TLS 54 KB free (was 46); after `irc stop`, back to 99 KB.

Peak stack use was measured through each task's worst case (an
ECDSA-checked install over Wi-Fi and from SD, get/put, a core dump
fetch, an IRC TLS handshake); stacks are now peak plus about 2 KB: loop
8 -> 6 KB, update 8 -> 5, storage 10 -> 6, irc 8 -> 6. The Debug Build's
console ring goes 6 -> 4 KB, serial TX 2 -> 1 KB, the GNSS UART buffer
1 KB -> 512 B.
On the device, with IRC on TLS: 46 KB free (was 31), an 18 KB low (was
9.4). The re-run of every worst case left at least 1.6 KB of stack free
in each task.

`r` in the GNSS App (or `gnss track start|stop`) records a Track to
/gnss/tracks/YYYYMMDD-HHMMSS.gpx: a point every 5 s once moved 5 m
(lib/gnss/track, 7 tests: haversine, the rule, GPX text, the file name).
It keeps recording with the App closed, shows REC in the Status Bar, and
announces start and stop with a Toast. It needs a card and the time;
switching GNSS off stops it. Tracks are written like Captures: past 90 %
card usage, until full. Storage Clean-up gets a GNSS tracks category.
A Track cut short by a reset or power loss has no GPX footer; the GNSS
Service closes such files at the next boot.
Verified on the device: a recorded Track and one interrupted by a reset
both parse as GPX 1.1 on the PC.

Position: the Fix line (or how long it has been searching), latitude and
longitude in decimal degrees or degrees-minutes-seconds (Settings ->

and UTC. Sky: the satellites by azimuth and elevation, coloured by
constellation, filled when used in the Fix, with used/in-view counts.
Tab switches. lib/gnss/geo_format holds the formatting, the locator and
the sky projection, host-tested (6 tests; locators checked against

Q61: a muted G while searching (or the receiver is silent), G with a 2D
Fix, G and the satellite count with a 3D Fix; nothing when GNSS is off.
Verified on the device by a window: 3D Fix, 9 of 11 satellites used
(GPS, GLONASS, BeiDou), HDOP 1.3, Status Bar "G9", and "gnss: clock set".

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/gnss: RMC, GGA, GSA and GSV into one GnssState: Fix type, position,
altitude, speed, course, HDOP, UTC time (trusted only with a Fix) and the
satellites in view across constellations. GSV sequences are kept per
constellation and signal band and merged per satellite with the stronger
SNR; GSA's system ID marks which satellites are used. 16 tests, using
lines captured from the device.

A temporary `gnss probe` command listens on both pin orders at 115200
and 9600. Only RX 15 / TX 13 at 115200 carries NMEA, as Meshtastic's
board file says; M5Stack's GPIO 8/9 are the keyboard's I2C bus. The
output format (NMEA 4.10, GSA system IDs, GSV per signal) is recorded in
docs/milestones/M2.md.

New commands everywhere: ls, rm and install <path> (Update from SD
without the Firmware page), all as Storage Service jobs. In Debug
Builds the console task answers get and put (one storage job per
transfer, file kept open, TCP flow control: about 300 KB/s, against
55 KB/s over serial) and screenshot (the RGB332 frame the UI composes
into). rdbg.py turns those into files and PNGs.
A failed put closes the connection: the rest of the file had been
parsed as commands. Card writes are retried 3 times after closing,
truncating to the last good byte and reopening, since FATFS keeps a
file in error after one failed write (seen once at 1.3 MB on this card).
onStorage() decides with one compare-and-swap whether the job or the
timeout wins, so an abandoned job can't touch a returned stack frame.
Verified on the device: screenshot; a get round trip byte-identical;
4 puts in a row; a tampered .ota refused by install; a good one put,
installed from SD, confirmed on Probation. The retry path itself has
not fired since it was added.

Every build now records at boot which version runs and, after a crash
restart, which one crashed (even across a Rollback). The core dump
summary (task, PC, reason, backtrace) is printed and raised as a
Notification; `crash` shows it later. After 3 crash restarts in a row
the firmware starts in Safe Mode: clock, Wi-Fi, Update Service and Debug
Console only (SafeMode, 2 host tests). A normal restart or a minute up
resets the count.
The main loop is now on the task watchdog (enableLoopWDT): Arduino only
watched core 0's idle task, so a stuck loop hung the device for good.
The Update Service restarts into an installed update by itself if the
main loop hasn't after 90 s.
Debug Builds: `coredump get` and `reset` are answered by the console's
own task; rdbg.py crash decodes the backtrace and rdbg.py coredump runs
esp-coredump, against ELFs archived by version and digest in .pio/elves.
The StorageService mutex is now made in the constructor: Safe Mode never
starts that Service, and `info` crashed on the null mutex, 29 times in a
row before the fix was pushed into Safe Mode over Wi-Fi.
Verified on the device: crash report and full core dump decoded over
Wi-Fi; Safe Mode at exactly 3 crashes, left by `reboot`; a hung loop
caught by the watchdog in 5 s; `reset` from the console task. ADR 0005.

cardputer-adv-debug (-DRORO_DEBUG, version +debug) adds a Debug Console:
after a token line, a client gets the last 6 KB of console output, live
lines (ESP-IDF logs included) and the serial commands. The socket task
only queues lines; the main loop runs them. Release builds compile none
of it. The token lives in ~/.config/roro9stack/debug-token, created by
_docker.sh and passed into the container.
All output now goes through `console`, which never waits for USB: a host
that was attached but not reading stalled the main loop up to 2 s per
line. New commands everywhere: info (slots with their versions from NVS,
since the framework stamps its own into each image), tasks, reboot,
boot other, log level, help. scripts/rdbg.py is the client; flash.sh
--debug builds it; CI builds both variants. ADR 0004.
Verified on the device: USB-flashed, then updated over Wi-Fi to a Debug
Build that confirmed on Probation; both slots hold Debug Builds.

scripts/sd_put.sh <file> [card path] sends a file (by default into
/updates, for Update from SD) without taking the card out. The serial
driver drops bytes once its receive buffer is full, so the transfer is
stop-and-wait: 1 KB chunks, each acknowledged once the Storage Service
has written it, into a 2 KB receive buffer. The device checks the
SHA-256 before renaming <path>.part into place, and gives up after 5 s
of silence or a card job that never returns. FileReceiver holds the
logic, with 12 host tests. About 55 KB/s: 1.6 MB in under 30 s.

Arduino-ESP32's initArduino() marks a PENDING_VERIFY image valid unless
the sketch overrides the weak verifyRollbackLater(). Every update was
therefore VALID before bootGuard() or Probation ever ran (otadata read
back state 0x2 on a crash-looping test build), and nothing rolled back.
The bootloader was never the problem. Override it to return true, so
Probation decides.

A deliberately crashing update looped forever on the device: the
prebuilt bootloader ignores ESP_OTA_IMG_PENDING_VERIFY despite the
app-side rollback config. UpdateService::bootGuard() now runs first in
setup(): it counts starts on Probation in NVS and, on the second
unconfirmed start, marks the image invalid and reboots into the
previous one. Confirming (or the Wi-Fi rollback) resets the counter.
ADR 0003 records the limit: a crash in the first milliseconds still
needs USB.

The Arduino network client treats a half-closed connection as closed,
so the device's reply after the sender's EOF was lost. The header
already carries the image size: UpdateParser::complete() lets the
device finish and answer while the connection is open. ota_push.py
half-closes only if no answer comes within 3 s, for older firmware.
