Tools > Admin: split the Radio tab's single "f,bw,sf,cr" comma-string
field (free-text keyboard) into 4 independent, type-appropriate rows --
Frequency (same digit-cursor DigitEditor Settings/Repeater use locally),
Bandwidth/Spreading factor/Coding rate (discrete-set LEFT/RIGHT stepping),
plus TX power and the 3 Routing numeric fields as number steppers and
Repeat as an ON/OFF toggle. Edits happen locally (zero mesh traffic per
keystroke); only Enter sends one combined `set`, Cancel sends nothing.
Full pre-release audit of all 16 commits since v1.22 (5 parallel focus
areas: display/font, keyboard/messages, Nodes/Admin, Bot/channels,
UITask+NodePrefs schema) turned up and fixed:
- Admin: fetched FK_NUMBER values weren't clamped to the field's range,
so a value already out-of-range could get stuck unreachable; fixed
commit-time float format noise (%.6f -> %.3f); Cancel/failed-login
always returned to the Nodes picker even when Admin was opened
directly from a node's Hold-Enter action -- now returns to wherever
it was actually opened from (AdminScreen::_from_picker).
- Keyboard: one-shot Shift was consumed after the *first* T9 multi-tap,
so cycling to the 2nd/3rd candidate always came out lowercase --
fixed by caching the cycle's caps state (t9_caps).
- Messages: history is numbered newest-first, so a message arriving
while scrolled up to an older one silently relabeled the view onto a
different message -- selection now shifts with the insert.
- Channels: onChannelRemoved() didn't clear ch_notif_override/
ch_notif_muted/ch_fav_bitmask despite its own contract comment
requiring it (now far more reachable via the on-device Delete);
an all-zero hex secret silently self-deleted the channel it was
just saved into (collides with the empty-slot sentinel) -- rejected.
- Room login: isRoomLoggedIn() indexed the login-tracking ring
directly instead of via its head offset, silently wrong once the
ring wraps (8+ rooms/session) -- the new on-device Logout depends
on this being right.
- Font/display: removed the now fully-inert Settings > Display > Font
toggle and the dead LemonFont.h (retired by the earlier misc-fixed
font unification, zero remaining includes); fixed a copy-pasted
"5x7" comment (font is 6x9), two meaningless dead ternaries, and an
OLED/e-ink inconsistency in the undefined-glyph fallback box offset.
- AdminField's `kind`/bounds fields no longer rely on default member
initializers inside aggregate-init: this toolchain's actual nRF52
build (unlike env:native) has no explicit -std= override, so it
predates C++14's aggregate-with-default-member-initializer rule.
Given an explicit constructor instead -- portable regardless of
standard, all existing field-table literals unchanged.
Docs updated to match: tools_screen.md (Diagnostics as a 3-tab
carousel, was documented as one flat screen), message_screen.md
(chat bubbles, newest-at-bottom, cursor mode, secret validation),
settings_screen.md (dropped the dead Font row), solo_ui_framework.md
(header menu_hint signatures, icon priority-drop, KeyboardWidget's
T9/alphabets/cursor-mode). release-notes.md gains the v1.23 section
covering all of the above plus the other 15 commits since v1.22.
Build-verified on WioTrackerL1_companion_solo_dual.

Replace the Lemon/default font-switch with a single misc-fixed 6x9 font
(full Latin/Greek/Cyrillic coverage), generated via a new tools/bdf2gfx.py
BDF-to-GFX converter. Removes the keyboard's per-render font-switch
workarounds now that one font fits its cell cleanly.
DiagnosticsScreen becomes a circular tab carousel (Live / System / Font),
adding a firmware+device+radio info tab and a per-alphabet rendering test
card covering every keyboard language.

Single-file Web Serial app for GitHub Pages. Connects to the device
over USB CDC, auto-detects <?xml…</gpx> frame from the Export GPX
action, and offers the file as a browser download with an editable
filename (defaults to trail_YYYY-MM-DD.gpx). Resets automatically
after download so back-to-back exports work without reconnecting.
Requires Chrome/Edge (Web Serial API). Enable GitHub Pages from the
repo settings pointing at the branch root or docs/ as needed.

Adds tools/trail_export.py: auto-detects the Wio port, waits for the
<?xml header, captures bytes until </gpx>, and writes a timestamped file
to tools/gpx/. Replaces the abandoned synthetic-FAT USB-MSC approach with
a simple host-side script.
- README: new "GPX Trail Export" section
- tools_screen.md: trail_export.py shown as the recommended download path,
cat/PuTTY kept as a manual fallback
- .gitignore: ignore tools/gpx/ output dir (mirrors tools/pngs/)

Firmware (7-byte header):
Byte 7 = display->screenshotRotation() — GxEPD2/GFX rotation value (0-3).
DisplayDriver::screenshotRotation() defaults to 0 (OLED).
GxEPDDisplay::screenshotRotation() returns display.getRotation(), the
live GxEPD2 value (reflects runtime setDisplayRotation() calls, not just
the compile-time DISPLAY_ROTATION macro).
Python decoder:
- Parse 7-byte header; pass rotation to eink_buffer_to_image().
- Implement all four GxEPD2 drawPixel coordinate transforms:
rot 0: phys_x=lx, phys_y=ly
rot 1: phys_x=vis_w-1-ly, phys_y=lx
rot 2: phys_x=vis_w-1-lx, phys_y=vis_h-1-ly (180° flip)
rot 3: phys_x=ly, phys_y=vis_h-1-lx
- vis_w/vis_h derived from log dimensions + rotation parity (no constants).
- Print rot= in the status line so the user sees which rotation was used.
This fixes the 180° rotated image seen with rotation=2 (portrait inverted)
without hardcoding a flip — correct for any rotation value.

The previous decoder always applied the rotation=1 (landscape) transform,
which caused three visible artefacts on a portrait (rotation=0) device:
- Content rotated 90° — wrong phys_x/phys_y mapping
- Content doubled/skewed — stride = buffer/log_width = 4000/122 = 32
instead of buffer/HEIGHT = 4000/250 = 16
Fix: infer rotation from aspect ratio (portrait: log_height > log_width).
portrait → direct mapping: phys_x=lx, phys_y=ly
landscape → rotation-1 map: phys_x=log_height-1-ly, phys_y=lx
Derive phys_stride from buffer_size // max(log_w, log_h) — the physical
HEIGHT is always the longer axis regardless of rotation, giving 16 bytes/row
for GxEPD2_213_B74 in both orientations.
No panel-specific constants remain; works for any GxEPD2 panel/rotation.

Firmware: add screenshotWidth()/screenshotHeight() virtual pair to
DisplayDriver (default: width()/height()). GxEPDDisplay overrides to
return display.width()/display.height() — the GxEPD2-reported values
that use WIDTH_VISIBLE (e.g. 122 for GxEPD2_213_B74), not the full
physical WIDTH stored in DisplayDriver (128). MyMesh uses these
instead of display->width()/height() for the screenshot header bytes.
Result for GxEPD2_213_B74 + DISPLAY_ROTATION=1:
header was 250×128 → now 250×122 (correct visible canvas)
Python decoder (tools/screenshot.py):
- Remove hardcoded EINK_PHYS_WIDTH=128 / EINK_VISIBLE_W=122 constants.
- Derive phys_stride from buffer_size / log_width (works for any panel).
- Fix phys_x formula: was (EINK_PHYS_WIDTH-1-ly = 127-ly),
now (vis_w-1-ly = log_height-1-ly = 121-ly for 213_B74).
Old formula addressed invisible columns 122-127; new formula correctly
maps logical rows 0..121 to visible physical columns 121..0.
- vis_w = log_height (no hardcoded trim; header now carries correct value).
This also works for square panels (e.g. 128×128 where WIDTH=WIDTH_VISIBLE):
header will carry 128×128, decoder produces a correct 128×128 image.

- Add lib/GxEPD2-patch/src/GxEPD2_BW.h: local patched copy of GxEPD2_BW.h
that exposes getBuffer()/getBufferSize() under ENABLE_SCREENSHOT guard.
Include guard (_GxEPD2_BW_H_) prevents double-inclusion of the installed
library version.
- GxEPDDisplay.h: use patched header via relative include when
ENABLE_SCREENSHOT so the patch takes precedence over the installed lib
(PlatformIO adds library paths before -I build_flags).
- DisplayDriver.h: add virtual getBuffer()/getBufferSize()/getDisplayType()
defaults (nullptr/0/0) under ENABLE_SCREENSHOT.
- SH1106Display.h / SSD1306Display.h / GxEPDDisplay.h: add concrete overrides;
getDisplayType() returns 0 (OLED) or 1 (e-ink).
- MyMesh.cpp/h: replace fragile C-cast with virtual dispatch in
handleScreenshotRequest(); extend 5-byte header to 6 bytes by appending
display_type so the host tool can decode the correct pixel layout.
- tools/screenshot.py: parse 6-byte header; add eink_buffer_to_image()
that decodes the row-major MSB-first GxEPD2 buffer with DISPLAY_ROTATION=1
(phys_x = 127-ly, phys_y = lx); dispatch on display_type.
- variants/wio-tracker-l1-eink/platformio.ini: add
[env:WioTrackerL1Eink_companion_dual_dev] with ENABLE_SCREENSHOT.
- variants/wio-tracker-l1/platformio.ini: unchanged (OLED env already exists).
Builds verified: WioTrackerL1Eink_companion_dual_dev SUCCESS,
WioTrackerL1Eink_companion_radio_ble SUCCESS (unaffected).
