L1: Tools > SOS, Back held 3 s. L2: the SOS app, the top button held 5 s
opens a slider over everything, the lock screen and a PIN too. Off by default.
The ACK word stops the repeats; who answered, what they wrote and when show on
Answered, and whoever answered needs no word after that. Beep plays
... --- ... at full volume until it's ended. While one runs the screen goes off
by 30 s, the GPS stays awake past its duty cycle until nothing more will be
sent, the repeater and the L2's WiFi rest. A received SOS gets a banner and a
place on the map, past Track loc, for 24 h.
The lock screen's slider restyled with it, shared as slideBar() / slidePoll();
the L2's Favourites and SOS pickers share pickContacts(). The engine is
ui-core/SosEngine.h, tested on the host. The message's format isn't final.

- Gallery: thumbnails 30 to a page, built only while the screen is still (a decode held the loop and a scroll read as a tap)
- segmented(): CLICK_TRIG, so a swipe starting on a screen's tabs doesn't switch them
- Settings > Device > Home apps removed (hold an app on Home instead)
- platformio.ini: a note that the L2 has no microphone on GPIO15 (verified on hardware)

Same gap as the screens had: the bot reply, a typed message's {temp} and
the placeholder lists read only the sensors, so a board without one (the
L1) answered !temp with n/a while its telemetry carried a temperature.
The fallback moves to LocalSensors.h, shared by the screens, expandMsg()
and sensorPlaceholders(); the latter now takes the chip's temperature.

The telemetry reply adds the MCU temperature, the screens read only the
sensors: on a board without a temperature sensor (the L1) the app showed
a temperature and the clock field '--'. The clock, Status and the L2's
Home now fall back to the chip's, like the reply. The bot's !temp and
{temp} still read only the sensors.

Settings > Display > Theme: Dark / Light (NVS mc_ui/light). The colour
tokens are set once before anything is built, so a change restarts the
device. Text on an accent fill is the new ON_ACCENT (it was BG, white
in the light theme); each accent has a deeper hand-picked light variant
that reads on white and takes white text. The map's empty-tile fill and
grid and the areas' outlines follow the theme too.

L2: a Flashlight app on Home (a lightbulb icon added to the fonts): a
white layer over everything, the backlight at 100 %, no auto-off; a tap,
the side or the top button puts it away and the brightness back.
L1: Tools > System > Flashlight, the whole OLED lit at full contrast
until a key. Not on e-ink.

WiFi starts and joins on internal RAM: ~42 KB the first time, ~25 KB after,
more for WPA. Free internal RAM had shrunk to ~20 KB after opening the map
(the tile decoder's 12 KB stack, the 32 KB I-cache, the DMA draw buffers,
UI statics), so a scan failed at once (esp_wifi_init: no memory) and a join
during a tile download timed out (AUTH_EXPIRE).
- ESP-IDF: CONFIG_SPIRAM_ALLOW_BSS_SEG_EXTERNAL_MEMORY, and the esp_timer
task stack 8 -> 4 KB (it uses ~0.4 KB). Rebuild the framework libs:
pio run -e Wio_Tracker_L2_idf_libs.
- PSRAM_BSS (EXT_RAM_BSS_ATTR) on the UI's big statics: QR codes, map
state, charts, lists. .dram0.bss 115 -> 66 KB.
- The tile decoder's and fetcher's task stacks in PSRAM.
Free internal RAM, idle: 48 -> 105 KB; WiFi up: 57 KB, 29 KB at the
lowest while downloading tiles.

Density from less chrome instead of smaller rows (ROW_H stays 44):
- titled screens drop the status bar; the title bar (APPBAR_H) holds back,
the title, the screen's actions and the time/battery on a pill; the status
bar returns for Home, the map, typing, the quick panel and the lock
- one radius (RADIUS) for everything tapped: buttons, tabs, choices, chips
- tabs are all segmented at TAB_H in the body (GPS, Clock converted)
- Nodes: chips row + sort + status line become one toolbar row with
Show / Order choices; Messages' All/Favourites is the same choice
- nav map: the target bar only while there is a target; the pin opens one
"Places" popup; back from a map options page restores the map and Map
tools as left, without a jump
- node detail actions at the top of the scroll; Home tiles fill the page
- rowsFit() leaves growing labels to the flex (a screen title cut to one
letter after Messages' filter changed)

Home and the lock screen draw HH:MM in ui-core/Lettering.h's block digits,
the seconds smaller on the same baseline, leaning smoothly per screen row.

- Quick panel: the screen under it is frozen and dimmed in one snapshot
(freeze::early), so the slide redraws an image and the panel; a tap or
swipe up under it closes it and nothing under it takes a touch. Tiles are
two pages of four with dots; tiles restyle only when their state changes.
- Home: a touch that starts on the top layer (the quick panel, the status
bar) is not a page swipe -- a sideways drag of the brightness slider over
Home ended the drag and turned the page under it.
- Keyboard: OK and hide don't put the cursor back on a field whose keyboard
is gone.
- BotScreen: adminRowBox -> centerRow (the sim build broke in 3293ac09).

- Battery curve: NodePrefs batt_curve_mv[11] (voltage at 0..100 %, all
zeros = built-in LiPo curve, sentinel 0xC0DE0032). ui-core/Battery.h
uses it for every percentage. L1: Settings > System > Batt curve list
(Left/Right 10 mV, Reset); L2: Settings > Power > Battery curve chart
with draggable points and a line at the cell's voltage.
- L2: the Nodes map is the full navigation map plus the nodes, Back
returns to Nodes; the favourite button is lit while it is one; pinning
to the Home dial uses a thumbtack (fonts regenerated); minimap dots
follow the accent; arranging tiles shows where they land while dragging;
emoji row in Diagnostics > Font.
- Sim hooks: sim_open nodesmap / accent@N / homeedit / battcurve.

A group row's text column (and an info row's key) grows into what the
controls on its right leave, and LVGL lays out children before their
parent, so its labels were first measured 1 px wide; LVGL also works out a
new label's height at its old width (0) before the real one. Each height
that changed then took another pass up the screen: 4-6 passes per screen.
rowsFit(), run before a frame's layout (LV_EVENT_REFR_START) and by
layoutNow() in place of every explicit lv_obj_update_layout(), gives each
new row's growing child the width the flex will give it, worked out from
the other children's styles and text, and labelFit() measures wrapping
labels at their real width up front. The grow stays, so a control that
can't be sized ahead only falls back to the old passes.
Layout on the device: Display page 34 -> 24 ms, Bot 33 -> 18, Quick
37 -> 22, Radio 26 -> 18, Diagnostics 20 -> 12. Sim screenshots of 26
screens unchanged.

Found by counting flushes on idle screens in the sim:
- The compose field's cursor blinked (a redraw every 400 ms) as soon as
a conversation opened, the keyboard hidden: lv_keyboard_set_textarea()
focuses the field, and LVGL only stops a blink when the cursor moves.
fieldFocus() sets the state and nudges the blink; also used for the
WiFi and channel fields, which left theirs running.
- lv_obj_align_to() restyles on every call, so the status bar's icons
redrew every second; placeLeftOf() moves them only when they move.
- Text colours set every second (nav bar, GPS status, Diag errors) go
through setTextColor(), which skips an unchanged colour.
- A LV_LABEL_LONG_DOT label writes its "..." into its own text, so
setText() never matched and rewrote it every refresh (the nav bar's
hint); labelShows() reads past the dots.
- The map area, the area-outline, trail and vector-label layers were
invalidated on every map refresh (every 3 s, a full-map redraw); now
only when the view or what they draw changed.
Idle map: 17 -> 1 flush in 5 s; list and settings screens: 0.

- The map screen's own fill is only painted where the map area doesn't
cover it (the strip it uncovers as it drifts in); the area and the
opaque status bar hide the rest. ~2 ms a frame.
- With every visible cell holding a tile, the map area drops its fill and
grid, which lie under the tiles anyway, and still reports that it
covers what's below (coversOwnArea, shared with the frozen popup
image). The Home minimap drops them the same way. ~5 ms a frame.
Full map frame ~50 -> 46-48 ms on the L2.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Measured on the L2 (steady full frames): Settings page 37.7 -> 31.4 ms,
Display 41.5 -> 37.9, Contacts 34.6 -> 32.9, Home 37.3 -> 32.4.
- styleSurface() leaves boxes in the page colour unpainted; styleOpaque()
for the screen and the status bar, which things slide under.
- group() cards clip their corners only while a row is held
(rowPressable(), shared by the tappable rows).
- rowSlider(): the track an opaque tint (theme::mix(), also behind
ACCENT_DIM) instead of 20 % accent blended every frame.
- Map buttons, pills, scale, nav bar and the Home minimap labels opaque.
- Screens drift in without the fading cover: its full-screen blend was in
every entrance frame (page 39 -> 29 ms).

- TileCache: request() hands z/x/y to a task on core 0, which renders into
a spare buffer; poll() swaps it into the LRU slot (stale results dropped
after drop()/invalidate()); the sim runs the job at once
- MapScreen / Home map place finished tiles as they arrive; the longest
UI stall with the map opening goes from ~340 to ~170 ms
- LVGL allocates from the PSRAM heap (lv_mem_psram.h), safe from both
tasks; LVGL's own pool is gone
- lv_conf: notes why LV_OS_FREERTOS with two draw units stays off
(measured slower: drawing is bound by PSRAM bandwidth)
- UI_PERF_TEST: the map (tile read/decode, pan, redraw), build time and
the longest loop pass per screen

Trail on the L2: 32768 points every 5 m, no simplification, no point
spacing setting; copied to the card every minute and restored at power-on.
The line keeps up with the position dot (incremental sync, pending point).
Map: a tap's finger jitter no longer turns follow off; the GPS button
shows when the map follows. The trail is drawn as one polyline with
breaks and off-view chunks skipped (an lv_line queued a draw task per
point).
Fewer rebuilds: conversation bubbles patched (new messages, delivery
marks), home mini-map dots reused, Nearby rows rewritten in place,
history read in runs and each file opened once.

- CPU at 80 MHz with the screen on after 2 s without touch or animation;
a touch restores the full clock before its frame is drawn
- setText(): periodic refreshes no longer redraw unchanged labels
(status bar, Home, lock, Diag, GPS, compass, clock, map, nav, nearby)
- map markers kept across the 3 s rebuild when unchanged
- app connected: the loop blocks until a BLE frame arrives
(serialFrameArrived / hasPendingFrames) instead of polling every 2 ms
- PSRAM: boot frame sprite and the HTTP response buffer released

- L1's MessagesScreen sends through UiCore::sendDirectText / sendChannelText
(its own copy of send + file + ACK tracking gone).
- ui-core/Telemetry.h: the dashboard fields (numbers, names, formats) and
sensor readings as text, each frontend passing its Style; L2 Home, L1's
clock page, lock screen, sensors page and GPS altitude use it.
- L2: the side button held in the first 8 s is the CLI rescue, as on L1.
- L1's repeater radio goes through rptctl.
- L1 Settings are built from SettingsSchema: short labels for small
screens, SCHEMA_* placeholders expand to the schema's sections, one
generic row (switch ON/OFF, bars for brightness / volume). 20 hand-written
rows and their tables gone; L1 implements applyDisplayPrefs /
applySoundPrefs. settings::text / step / indexOf shared with L2.
- Schema: auto-off gains 5 s; the advert sound scope reads "Direct".

Hold an app on Home (or Settings > Home apps) to arrange them: every app
is shown, hidden ones dimmed with a +; a drag drops the app into the slot
under the finger, held at a screen edge it goes to that page; a tap hides
or shows it. Settings stays shown. The order is kept in NVS (letters per
app, lower case = hidden), saved on Done or on leaving Home.
Roadmap: note the speaker-knock experiment (DAC ramp didn't help).

Every toggle / stepper wrote the prefs file straight away (0.1-0.6 s on the
ESP32's SPIFFS), which stuttered the UI and wore the flash. prefsSave() now
only marks them dirty; they're written once when the screen is left, when the
display goes off, or after 60 s at the latest -- the L1's approach. Shutdown
and the pre-restart OTA save still write immediately.

It was a muted prefix on the date line, easy to miss. clockFace() -- the
digits and a small AM / PM on their baseline -- is shared by Home and both
lock screens (the PIN card showed no AM / PM at all). The date loses the
prefix.

A square grid drawn under the tiles (map, Nodes map, Home minimap), its step
a round distance for the zoom in metric or imperial units, with a scale bar
one step long; gives position and scale where no tile is loaded. The
missing-tiles hint moves up, off own position.

Waymarked Trails' transparent hiking layer, kept in /sdcard/maps-trails and
blended over the base tile at render time (Map tools > Hiking trails, NVS).
An area download fetches each tile's trails after its base tile, so
re-running an area on the card adds just the trails; with live tiles on, a
shown tile missing its trails has them fetched. Tiles without a trail are
stored as 0-byte files (no cluster on FAT).

- Unread badge on Home tiles sits in the top-right corner, clear of the icon
- Minimap with no GPS fix: the saved position (hollow dot), else where the
map was left, else the default view; a hint when no tiles cover the area
- Screen header 38 px, so the back and header buttons get a margin
- Bluetooth / WiFi connected shown in the accent colour; charging bolt green

Home pages: favourites, the clock (tap for Clock) with three telemetry
fields picked by holding one (shared dashboard_fields), a minimap that
frames you, live shares and the target (tap for the Navigation map), and
the apps in 3x2 pages. The side button now returns to the clock page with
a cross-fade instead of going back. Home moves to HomeScreen.h.
