Post-review cleanups, no behaviour change:
- botScanCommands() parsed the command name and its two args with three
near-identical read-token loops; extracted a single readToken() lambda.
- Fn+Esc lock branch turned the display on twice (the unlock arm repeated
what the branch head already did); dropped the redundant call.
- setGpioMode()'s comment said "Cycle" (cycling lives in GpioScreen); now
describes what it actually does — set a specific mode + persist.

- Bot Actions (!buzz/!gps/!advert/!gpio1-4) ran their side effect
immediately during botScanCommands(), before quiet-hours/cooldown/
per-contact throttle were checked -- those gates only suppressed the
reply text, not the actual buzz/GPS toggle/advert/pin write. botCommandReply()
now only records what was requested; applyPendingBotActions() runs the
deferred effects once a wrapper's throttle checks pass and the ack sent,
mirroring the existing _locfix_requested pattern. resetPendingBotActions()
clears everything on every throttled/aborted path.
- CardKB's Fn+<letter> accent-popup shortcut bypassed the locked-input gate
(it called into KeyboardWidget directly instead of through the
enqueueKey()/dequeue path every other key uses, so it wasn't discarded
while _locked). Now checks _locked itself.
- Since a locked device now correctly ignores CardKB entirely, Fn+Esc
(single press) is added as CardKB's own lock/unlock gesture -- otherwise
a CardKB-only setup had no way to unlock. Esc rather than the adjacent
Fn+Backspace, to avoid an accidental press.
- botScanCommands() now parses up to two arguments per command instead of
one. Used by "!gps fix [seconds]" to override the default 90s timeout
(clamped 15-300s) for a poor sky view where 90s isn't always enough to
reach isLocFixReady()'s HDOP/satellite bar.

Satellite count alone is a poor proxy for fix quality -- few satellites
in good geometry can beat many in poor geometry. LocationProvider now
exposes getHDOP() (default -1 = unsupported); MicroNMEA implements it.
isLocFixReady() prefers HDOP <= 2.0 when available, falling back to the
old >=8 satellite threshold for providers that don't report it (e.g.
RAK12500/u-blox).

Same fix as hotfix/admin-login-timeout (96b44460). AdminScreen's only
guard was "_phase == LOGIN" (true for any node sat at the login
screen), not that the reply actually named _target. Now also checks
pub_key against _target.id.pub_key.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Same fix as hotfix/admin-login-timeout (5a5ebe9f). UITask::onRoomLoginResult()
dispatches by whichever screen is currently shown, not by who sent the
request, so a reply arriving after AdminScreen gave up (Cancel or the
timeout fix) could land on MessagesScreen instead and persist its own
unrelated _login_pw as the "confirmed" password for that pubkey.
MyMesh::cancelUiPendingLogin(pub_key) stops tracking the request on
give-up so a late reply matches nothing instead.

Same fix as hotfix/admin-login-timeout (05609019). Tools > Admin >
System > "Admin password" changes the remote's admin credential but
never updated this device's saved copy, so the next login retried the
password just replaced -- likely the actual trigger behind the
"stuck on Logging in..." report. Parses CommonCLI's "password now: <v>"
success echo and saves that as the new on-device password.

Turns GPS on (if it wasn't already), waits for a stabilised fix
(isValid() + >=8 satellites, then averages 10s of readings), sends the
position, and restores GPS to whatever state it was in before -- up to
a 90s timeout, after which it reports a partial fix (if it got any
samples) or plain failure.
Replies in two parts since a fix takes seconds-to-minutes, unlike every
other bot command here: an immediate "acquiring fix..." ack (through
the existing synchronous command path), then the actual position as a
separate follow-up message once ready, delivered to whichever
destination (DM/room/channel) the request came from. Only one fix can
be in flight at a time -- a second request while one is pending gets an
immediate "already pending" instead of silently replacing it.

AdminScreen's LOGIN phase had no timeout, unlike its COMMAND phase
(_cmd_deadline_ms). If a login reply never arrived -- most commonly a
saved password gone stale after the remote node's password changed,
silently dropped instead of nacked -- the screen stayed stuck with only
a manual Cancel to escape.
sendRoomLogin() now returns the same est_timeout sendAdminCommand()
already exposes; AdminScreen uses it to arm a deadline (poll(),
mirroring the COMMAND-phase pattern) that forgets the stale password
and returns to the picker on expiry, same as an explicit login
rejection already does.
Same fix as hotfix/admin-login-timeout (23f43cac), split out of this
branch's other in-progress work.

Add Settings > Keyboard "Ext. KB" row (boards with a CardKB-capable I2C
bus only): switching it to Compact hides the letter grid and special-row
icons in favour of a one-line status (script/page, caps) plus a Fn-shortcut
reminder, since an external-keyboard typist never looks at the on-screen
grid. Accent/placeholder popups still render as before. Off by default.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
CardKB is level-triggered (repeats the held byte every poll) and its Enter
key collided with the on-screen keyboard grid's own commit action, causing
duplicate characters and accidental message sends. Debounce polling and use
the CardKB v1.1 Fn modifier (confirmed working on real hardware) instead of
tracking navigation state: plain Enter now behaves like the physical centre
button, Fn+Enter submits, Fn+Tab opens the Hold-Enter equivalent, and
Fn+<letter> opens that letter's accent popup directly.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Auto-detected at boot on Wire1/Grove (addr 0x5F) -- no setting to flip, and a
no-op on boards without that bus or with nothing attached. This UI's key
codes (KEY_LEFT/UP/DOWN/RIGHT/ENTER/CANCEL) already match CardKB's own byte
protocol, so most input needs zero translation and flows through the same
key queue as physical buttons.
Two bytes get remapped in UITask::pollCardKB():
- Enter, only when the on-screen keyboard's plain grid state is active (no
placeholder/accent popup, not in cursor-mode), becomes a new KEY_KB_ENTER
sentinel meaning "submit the field" -- reusing plain KEY_ENTER there would
insert a stray character, since a CardKB typist's row/col never reflect an
intentional grid selection. Everywhere else Enter is untouched, so
selecting a placeholder or committing an accent still works normally.
- Tab (otherwise unused) becomes KEY_CONTEXT_MENU, standing in for the
"Hold-Enter" long-press gesture CardKB has no way to produce -- without it,
~30 context menus across the UI (message reply/navigate, Bot/Admin/
Repeater, ...) would be unreachable from the keyboard alone.
KeyboardWidget gains a direct-typing path: printable ASCII inserts straight
at the cursor bypassing the grid, Backspace deletes, KEY_KB_ENTER submits.
Build-verified: WioTrackerL1_companion_solo_dual and

The bot outgrew "auto-reply" once it gained Actions (!buzz/!gps/!advert/
!gpio1-4) that control device hardware remotely, not just answer messages.
Renames the Tools screen entry and all doc cross-references; already-shipped
release notes (v1.23) are left as-is to match what actually shipped under
that name.

The room server never supported RX boosted gain, while the repeater
does. Three consequences on SX1262/SX1268 boards:
- boosted gain was never applied to the radio at boot, so a room server
ran in power-saving RX mode while an identical repeater ran boosted -
a real receive-sensitivity difference with nothing pointing at it
- _prefs.rx_boosted_gain was never initialised (the prefs are memset to
0 before defaults are set), so it defaulted to off
- 'set radio.rxgain on' replied "Error: unsupported" but CommonCLI had
already written the value to prefs and saved them, so a stale setting
survived reboot and was never applied
Mirror the repeater's implementation: initialise the pref default under
the same USE_SX1262/USE_SX1268 and SX126X_RX_BOOSTED_GAIN guards, apply
it during radio init, and override setRxBoostedGain() so the CLI reports
success and takes effect.
Built Heltec_v3_room_server (SX1262) and LilyGo_T3S3_sx1276_room_server
(guards compile out cleanly).
- Auto-Reply Bot gains Actions (!buzz/!gps/!advert) behind a new per-target
toggle nested under Commands (bot_actions_dm/ch/room); off by default.
- Bot Trigger fields accept comma-separated multiple phrases, matching any
one fires the reply.
- New user-assignable GPIO feature (Wio Tracker L1): !gpio1..!gpio4 bot
commands plus a Tools > GPIO screen. Each pin cycles Off/Input/Output;
GPIO1/GPIO2 (P0.02/P0.29, the nRF52840's AIN0/AIN5) also offer a read-only
Analog mode via direct SAADC access. GPIO3/GPIO4 (P0.09/P0.10) are the
chip's NFC1/NFC2 pins, repurposed as plain GPIO via a one-time UICR
NFCPINS bit-clear in initVariant() (adapted from Adafruit's own
nfc_to_gpio example) -- confirmed working on real hardware.
- Fix: DM/room reply-prefix ("@[nick] ") stripping happened at the wrong
layer, hiding the "To:" header on DM replies and leaking the raw prefix
into room messages' list view; a related mismatch had the history
scrollbar's sizing pass wrap room messages with the sender name still
attached, disagreeing with the actual rendered text.
Build-verified: WioTrackerL1_companion_solo_dual and
WioTrackerL1Eink_companion_solo_dual both compile and link clean
(sizeof(NodePrefs) confirmed 2720 via real build, not guessed).

setTxTimeoutMs() and setTxBufferSize() are HWCDC-only APIs; calling
them on HardwareSerial (UART-bridge boards like T-Beam) fails to compile.

Switch ESP32-S3 KISS modem environments to HWCDC and move outbound KISS writes to a non-blocking queued frame path so loop() and TX completion keep progressing when the host reads slowly. Add native backpressure regression tests and correct the native_kiss_modem test filter so this suite runs directly with pio test.
"+ Add channel" jumped straight into a generic Name+Secret form, so the
"hashtag channel" convention documented in docs/companion_protocol.md
(secret = first 16 bytes of sha256("#topic")) was only reachable by
already knowing to type a literal "#topic" into the passphrase field --
nothing in the UI surfaced it. The phone app instead shows an explicit
channel-type picker; this adds the same on-device.
"+ Add channel" now asks Public / Hashtag / Private first:
- Public commits immediately with the well-known default channel's name
and secret (8b3387e9c5cdea6ac9e5edbaa115cd72, confirmed to match
MyMesh.cpp's PUBLIC_GROUP_PSK and the docs' published key) -- useful
to restore it if deleted.
- Hashtag shows a single Topic field; Save synthesizes name="#topic" and
derives the secret via the existing SHA-256 passphrase path -- same
underlying mechanism Private already had, just discoverable without
knowing the "#" convention.
- Private is today's manual Name+Secret form, unchanged.
Editing an existing channel skips the picker (no ambiguity to resolve
there). Extracted hexToSecret() out of deriveSecret()'s hex-mode branch
so Public's fixed key parses through the same code instead of a second
hand-rolled loop. No other file needed changes -- openAdd()/openEdit()/
active()/render()/handleInput() keep their existing signatures.

UITask::newMsg() (fired for every incoming DM/channel message) triggers a
3s "Msg: <sender>" overlay drawn on top of whatever screen is current --
including the shared KeyboardWidget when it's occupying the full screen
for text entry (message compose, room/repeater password, channel name,
device name, admin custom command, ...). A message arriving mid-typing
blanked out the letter grid for the full 3s with no way to see what was
being typed.
KeyboardWidget now tracks whether it was actually rendered this frame
(_visible, set at the top of render(), cleared by the new beginFrame()).
UITask's render loop calls _kb.beginFrame() before curr->render() and
skips the alert overlay when the keyboard turned out to be what got
drawn -- covers every screen that shares _kb, not just message compose.
The alert itself is unaffected (still fires, still expires after 3s) --
it just doesn't draw over the keyboard.

Renamed the vestigial Lemon/default font-switch naming (setLemonFont/
isLemonFont/drawLemonChar/lemonXAdvance/_use_lemon -> setSingleFont/
isSingleFont/drawGlyph/glyphXAdvance/_single_font) across DisplayDriver.h
and both concrete drivers -- both have been permanently single-font for
several commits, so the old names invited a future reader to think a
real switch still existed. Pure identifier rename, no logic changed.
Also extracted the byte-identical "SenderName: " prefix-splitting in
MyMeshBot.h's tryBotReplyChannel()/tryBotChannelCommand() into a shared
botChannelSenderSplit(), mirroring the existing botRoomSenderName().

Page 0 was hardcoded to Latin -- Cyrillic/Greek could only ever be the
second, cycled-to page. Settings > Keyboard's Alphabet row splits into
Main (which script the keyboard opens on by default) and Additional
(the second one reached via #@/abc), so a Cyrillic/Greek typist can make
their own script the default instead of always landing on Latin first.
Setting Additional equal to Main collapses back to a 2-page cycle (that
script + Symbols), same rule the old Latin-hardcoded design already used
implicitly.
KeyboardWidget.h: cellStr()/t9GroupStr() now dispatch through
scriptCellStr()/scriptT9GroupStr(), treating Latin as an ordinary peer of
Cyrillic/Greek instead of a special case; scriptHint() replaces
altAlphabetHint() so the #@/abc key's "next page" hint is correct
regardless of which script that lands on; the accent popup's gating
checks the current page's actual script instead of assuming page 0 is
always Latin. Removed the now-dead pageIsAltAlphabet().
NodePrefs gains keyboard_main_alphabet (schema sentinel 0xC0DE001F ->
0xC0DE0020, same append-at-tail/clamp-on-load pattern as every prior
schema growth this file uses). Verified via a real build that the new
field lands in existing tail padding -- sizeof(NodePrefs) is unchanged
at 2712.

Replaces the 8 separate Latin-diacritic alt-alphabet pages (Polish, Czech,
Slovak, German, French, Spanish, Portuguese, Nordic) with one popup: Hold
Enter on a Latin letter that has accented variants (a c d e i l n o r s
t u y z) opens a floating horizontal strip of that letter's accents,
anchored over its own row so the grid stays visible underneath (LEFT/
RIGHT picks, Enter inserts via a new shared insertGlyph() helper, Cancel
dismisses). Holding a letter with no variants is a no-op. Cyrillic/Greek
remain full alt-alphabet pages; NodePrefs::keyboard_alt_alphabet shrinks
from 11 to 3 values accordingly -- an old saved Polish..Nordic value just
clamps to Latin via DataStore.cpp's existing range check, no migration
code needed.
Freeing Hold-Enter on letter cells required moving cursor-mode's own
trigger: UP from the top letter row now enters it instead of wrapping to
the special row. To keep that wrap reachable, cursor mode's UP/DOWN
(Home/End) continue the wrap once already at that boundary -- UP again
lands on the special row, DOWN again back on the letter grid -- reusing
the same proportional column mapping the old direct wrap used.
Diagnostics' font-coverage sample swaps its 8 per-language lines for one
line sampling the new accent table. Docs (message_screen, settings_screen,
solo_ui_framework) and release-notes updated to match.

Long field labels ("Flood advert interval (h)", "Frequency (MHz)") were
ellipsized to nearly the full row width with no reserve for the value
column, so a label could run under/through the value or digit editor on
the row currently being edited. Only rows showing an inline value now
reserve room before valCol(); other rows keep the full width as before.
Separately, the Frequency digit editor (4 int + 3 dec digits, needed for
Admin's wider 150-2500 MHz range vs Repeater's 3-digit range) drew all 8
digits flush to the screen edge, landing the thousandths digit exactly
under a visible scrollbar's reserve column. Shifted left by that reserve,
matching the plain-value branch's existing scrollbar-aware positioning.

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.

- MessagesScreen: shrink message boxes to fit content and anchor them
right (outgoing) / left (incoming), like typical messengers; move
the [+ send] compose button to the right edge to match; fix its
frame margins (no descenders in the label made the symmetric padding
look uneven) and reclaim the freed 2px for the message list.
- KeyboardWidget: add Hold-Enter cursor-positioning mode (LEFT/RIGHT
move, UP/DOWN jump to start/end, Enter/Cancel exit) with a visual
"CURSOR MODE" indicator, so edits and inserts can target any point
in the typed text instead of always the end.
Message history (DM + channel) now stacks bubbles upward from the compose
row instead of the header, so the newest message sits at the bottom like
a typical messenger, with older messages progressively above. UP/DOWN and
the scrollbar direction are swapped to match; the newest bubble now keeps
the same breathing-room gap against the compose row as it does against
another bubble, instead of touching it.
Keyboard: Shift is one-shot by default (capitalises just the next
letter, then reverts), with Hold-Enter on Shift toggling a persistent
caps-lock for the old sticky behavior. Hold-Enter on Backspace clears
the whole field in one action.

- GxEPDDisplay now uses the same single misc-fixed 6x9 font as the OLED
driver (Lemon retired there too), with baseline math updated for the
new ascent.
- Clock Tools' Alarm screen: Repeat and Armed now respond to LEFT/RIGHT
like every other multi-value/toggle field in Settings, not Enter-only;
Hour/Minute merged into one Time row edited with a hand-rolled HH:MM
digit cursor (like the Timer's), replacing the two-row DigitEditor
popups; Repeat's "Off" label now matches the codebase-wide ON/OFF
casing.
- Top status bar: battery icon now shares the same box height as the
other status icons (Bluetooth/mute/etc.) instead of standing 2px
taller, and its charge nub is properly vertically centred instead of
drifting off-centre at non-multiple-of-4 box heights.
- Small settings-gear icon glyph tweak; wio-tracker-l1 screenshot build
variant now enables DUAL_SERIAL.

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.

A device administering itself via the Admin tool read as awkward, so the
local mode is gone and its options relocated to Settings.
- AdminScreen is remote-only: drop the CHOOSER phase, _local_mode, the
LocalField/LocalKind model and activateLocalField/commitLocalField.
Phases collapse to LOGIN/COMMAND/REPLY, entered only via startFor().
- Tools > Admin opens straight to the Nodes picker (ACT_ADMIN ->
pickAdminTarget()). Backing out of a command screen returns to that
picker; the picker's Cancel returns to Tools. gotoAdminScreen() removed.
- Settings > System gains Name (keyboard-edited node_name) and Reboot
(action row, placed last so it isn't the default cursor). Radio + TX
power were already in Settings; Send advert is the home ADVERT page.
Docs: tools_screen.md Admin section rewritten remote-only; settings_screen.md
System table gains Name + Reboot.

Tools > Admin now opens on a This-device / Remote-node chooser. "This
device" is a login-free 2-tab carousel (System: Name/Radio/TX power/
Lat/Lon, Actions: Send advert/Reboot) mapped onto NodePrefs/sensors and
reusing Settings' own apply chains -- no CommonCLI port. "Remote node..."
opens Tools > Nodes in a pick-mode (borrow-another-screen's-list idiom),
and Nodes gains an "Admin" Hold-Enter action; both converge on the single
canonical UITask::openAdminFor() -> AdminScreen::startFor().
Also:
- KeyboardWidget: opt-in PlaceholderRefreshFn hook for contextual {}-key
CLI command-name completion (word-replacing); default behaviour and all
other keyboard uses unchanged.
- TabBar: ellipsize() re-measures the real "text..." candidate per step
(+ width clamp) so dots can't spill into a neighbour/reserved icon.
- ChannelsView: form rows truncate instead of wrapping.
- Reboot moved off the default-selected Actions row (fires with no confirm).
