- 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.

503/429 slow the pace down, transport errors retry after 2/8/30 s, failed

- CMD_GET_SCREENSHOT on colour screens: display type 2 (RGB565 LE),
32-bit payload size; ui-lvgl captureFrame() shared with the SD BMP
- ENABLE_SCREENSHOT in the L2 build; tools/screenshot.py decodes type 2
- docs and READMEs point to solo.marekzegarek.com/#pc-tools

- 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

- The WiFi and Bluetooth rows rebuilt the whole Settings page to update
their hint, cutting the switch's animation short; the hint is now
rewritten in place (rowHintSet). The "Bluetooth on" echo toast is gone.
- Map download: a 404 gets the same one retry as other errors
(OpenTopoMap sends the odd 404 for a tile not rendered yet), and a
download that ends with gaps says "Done, N missing - download again".

- build-solo-sim.yml clones LVGL at the version pinned in
solo/wio-tracker-l2/platformio.ini and builds the SIM_UI=lvgl sim into
wasm/lvgl/ of solo-sim-wasm.zip, for the site's device switch.
- build_wasm.sh: LVGL_DIR can be overridden (CI has no .pio libdeps).
- sim_test_set_node_name(): names a sim node, for site screenshots.

Short pages by feature (getting started, messages, contacts, navigation,
tools, settings, lock, hardware) instead of one page per OLED screen, with
Wio Tracker L2 differences as notes; facts checked against the code
(keyboard scripts vs. hold-for-accents, {batt}/{dist}, L2 limits and
settings layout). Developer guides and build flags under docs/solo/developer.
Old docs/solo_features and its ~50 screenshots removed; a hero banner and
three simulator screenshots added; links updated.

Working plans (docs/development, docs/design redesign notes) removed; the
two developer guides moved to docs/developer/. README cut to devices,
flashing, links and building (Wio Tracker L2 added); its feature list and
doc tables moved to docs/solo_features/README.md. RELEASE.md describes the
Solo release flow. Upstream's GitHub Pages workflow (docs.meshcore.io)
dropped, CLAUDE.md untracked, Buy Me a Coffee back in FUNDING.yml.

The phone app's offline queue took 256 x 177 B = 45 KB, which with the
on-device UI left the L1 ~5 KB of heap from boot (the sign buffer of #38
never fit). The UI keeps its own message history, and a full queue drops
the oldest channel messages first, so 128 is plenty: the L1 heap now has
~27 KB free. L1 OLED / e-ink, ProMicro, T-Echo Lite, both GAT562; the
upstream variants/ are unchanged (build_unflags in solo/).

The SD card (message history) could be lent to a computer from the lock
card before the PIN was entered. While locked with a PIN, usbPoll() no
longer reacts; a cable plugged in meanwhile is offered once unlocked.
The plain-text NVS PIN never shipped, so there's nothing to migrate.

Since bf1e6fca kbApplyCapsUtf8 wanted 4 bytes free before each codepoint;
the ABC grid passes a 3-byte cell buffer, so every cell came out empty (T9
and CardKB Compact draw no such cells, so it went unnoticed). A codepoint
is now copied when it fits with the NUL.

The contributor's feature -- a PIN asked before the screen unlocks, on
boot, and when the magnet cover opens, stored as a salted SHA-256 -- on
top of this branch, with:
- ui-core/ScreenLock.h: set / check / isSet and the tries limit, shared by
L1 and L2. isSet looks at every byte (the PR tested only the first, so one
PIN in 256 silently disabled the lock). 5 misses pause entry for 30 s.
- NodePrefs: the fields at the tail after quiet hours, sentinel 0xC0DE0031,
sizeof 2880; an older file's bytes there are cleared. A sentinel bump no
longer resets display_brightness_pct from a file that already has it.
- DataStore: no AGPL header (the project is MIT), no whitespace churn.
- Keyboard: the number pad is a widget flag (pin_mode) with a prompt in the
preview ("New PIN", "Again", "PIN"), not keyboard_type = 2 written into the
prefs and restored after.
- L1 Settings: "Lock PIN" right after the schema's "Lock screen" row, typed
twice, at least 4 characters, saved at once (a power-off right after
setting it kept no PIN). Home is told about a boot-time lock once it
exists (also fixes booting with the cover closed).
- L2: the screen PIN moves from plain text in NVS to the same hash in
NodePrefs; the old one is migrated on first boot and removed. The pad
unlocks as soon as the hash matches from 4 digits on.

CMD_SIGN_START promised the app 8K before a malloc it never checked. On
the L1 the nRF52 heap has ~5K free from boot, so the malloc always failed
and every CMD_SIGN_DATA answered ERR_CODE_BAD_STATE. Now it allocates
first, halving down to 256 B, and reports the size it got; nothing at all
is an error on SIGN_START itself.

- 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".

- Dead code gone: anim::fadeHide, radioctl::presetCount, the L2 board's
setSdPower / setGrovePower / expanderOK (awRead, gnssReset now private).
- buttonBar() / barButton() replace 7 copies of the popup button row.
- confirmBody(): one red-button confirm for reboot / power off, reset
counters, admin commands, preset and scope delete.
- tapConfirmed(): the 11 "tap again" buttons share one mechanism, 3 s
everywhere, the label restored when left alone.
- noteLabel() for ~30 wrapped notes.
- localTm() in NodePrefs.h and one MONTHS table: lvgl, MsgExpand, the L1
clock and lock screen.
- The sim keeps UI settings in an in-memory nvs::, so one set of load /
save helpers serves both.
- Asleep, the loop wakes every 50 ms (the button / touch poll), not 20.

Settings > Sound > Quiet hours (L2: its own group; L1: Quiet hrs / from /
until): from quiet_from to quiet_to (local hours, wrapping past midnight)
the buzzer is muted and a message doesn't wake the screen; the clock alarm
still rings. A manual mute or unmute inside the window stands until the
window ends. Off with the clock unset.
NodePrefs gains quiet_hours / quiet_from / quiet_to (appended to the file,
sentinel 0xC0DE0030; sizeof 2832 on nRF52 and ESP32), off by default,
22:00-07:00. hourInWindow() / localHour() are shared with the bot's quiet
hours. soundctl::tick() replaces autoTick() (Auto and quiet hours).
Also fixes the L2 side-button mute: it went by the mode, not by whether
the buzzer was muted, so with Auto + an app connected (and now quiet hours)
the first press muted instead of unmuting.

The Noise tab held the L2's interference hunt: parts of the board off one
by one, a slow cycle for a second radio, a spike hunt and three sweeps
(~90 s, L2 only). It is now one Measure: the noise floor on the mesh
frequency (median and 10th percentile of 5 s) and a +-1.1 MHz sweep round
it, ~12 s, with a short legend for reading it. Works wherever the variant
defines the radio.

Map tools: TRAIL, LIVE SHARE and ARRIVAL ALERT each with their own options
page (that section of Map options; back returns to Map tools), the arrival
alert switch where its state is shown, OFFLINE MAPS (Map areas, Live
tiles; the separate Download an area is gone -- a running or unfinished
download shows at the top of Map areas) and LAYERS.
Map areas: picking one frames it on the map above a small sheet (no Show
button, the map above isn't dimmed); closing the sheet, however it's
closed, puts the map back where it was and drops the outline -- it used
to stay on the map. New popup kind POP_BOTTOM.

The UI runs on Arduino's loop task, whose stock 8 KB stack had 340 B left
at its deepest point; a screenshot's file write went past it and reset the
device. The loop stack is now 16 KB (measured peak ~7.8 KB) and the
screenshot's line buffer is static. Diagnostics names the row
"UI stack free (lowest)".
With a cable in at boot, the USB popup waited for nothing and showed over
the splash; it now comes once the splash has faded.
Adds docs/development/plan-next.md, the plan up to the merge into dev.

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).

- USB through TinyUSB (ARDUINO_USB_MODE=0) instead of USB-Serial/JTAG: the
serial port stays, and plugged into a computer (enumerated, the bus not
suspended -- on battery an unplug only shows as a suspend) the device asks
"Charge only / USB drive". As a drive the firmware lets go of the card and
the computer gets its sectors; ejected or unplugged, the device restarts.
- Incoming messages: a banner slides down from under the status bar (icon,
sender or channel, two lines of the text from history); a tap opens the
conversation (not while locked), a swipe up dismisses it, not shown for
the conversation already open. Toasts moved up there too, under the banner
when both are up; the ones only echoing a switch or a choice are gone.
- Storage > Format card: a popup saying what goes, then Format tapped twice;
one FAT32 volume over the whole card (readable or not), then a restart.
- A deliberate restart shows a full "Restarting..." screen with the reason
instead of the screen just freezing.
- The screenshot flash is a thin frame round the edges: a full-screen fade
redrew all 320x240 each step and tore.

Two views, swapped with left / right: a polar sky plot (filled = used in the
fix, hollow = tracked, a pixel = no signal) beside fix, used / in view, HDOP,
PDOP and time to first fix; and a signal bar per satellite (used first, a
dotted 30 dB-Hz line) under per-constellation counts. The GPS stays awake
while it's open. Data from GpsSky (-D GPS_SKYVIEW, now on the L1 solo build).
The simulator's made-up sky moves from the L2's GpsScreen into
helpers/sensors/GpsSkySim.h, so both sims show it.

- Settings > WiFi keeps up to 8 networks (NVS "s0".."s7" / "p0".."p7"; the
single one older builds saved moves over). A tap loads one to change its
password, Forget asks with a second tap, a scan marks the known ones.
- Map downloads, live tiles and updates join the strongest saved network in
range (a short scan first when more than one is saved), else the newest
one -- which also covers a hidden network.
- Save joins the network once: "password OK", turned away (forgotten again,
the form keeps it to fix) or not in range (kept, checked later).

- Side button held + top button saves the screen, popups and toasts included,
to /sdcard/screenshots/scr_NNNN.bmp (24-bit BMP). The flush callbacks copy
one forced full re-render into a PSRAM buffer. A white flash and a toast
confirm it. The side button's mute now fires on release, so holding it a
little long before the top button doesn't also mute. In the sim, the page's
Screenshot button downloads the file.
- The lock screen goes dark after 30 s even with auto-off at Never (a boot
PIN, a pocket wake-up, a message), and sooner if auto-off is shorter.

helpers/esp32/InternalFS.h picks the filesystem: -D ESP32_LITTLEFS mounts
LittleFS on the same "spiffs" partition, otherwise SPIFFS as before. Only the
L2 LVGL envs set it; every other ESP32 board is unchanged. A settings save
drops from ~0.5 s to ~80 ms and the files survive power loss mid-write.
No migration: the first boot formats the partition (fresh identity).
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
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.

The triangle draw descriptor's colour fields lost their bg_ prefix and style
getters take an lv_part_t. 9.6 sizes flex containers through the layout, so
popups no longer shrink when pulled past their end: lvgl_patches.py goes.

Flash +73 KB.

While nothing is connected, every 5 s: if advertising has stopped (a host
reset ends it with no disconnect to restart it), start it again. A link up

LVGL 9.2.2 measures a SIZE_CONTENT box from its children as scrolled, so an
elastic pull past the end of a capped popup list shrank it by the overshoot,
again on every pull. lvgl_patches.py fixes calc_content_height in the
downloaded library (a build middleware for PlatformIO, called directly by the
sim's build_wasm.sh).
The five popups that each built the same panel now share popupOpen() (fit to
content / full height / under the status bar).

The spike (a throwaway ui-oled frontend, not kept) ran in the simulator but
never got past building its screens on the L1: LVGL's pool and stack sit
outside the heap and UiCore needs 27 KB of it in one piece. Flash was fine.
Decision: no LVGL on the nRF52 boards; the v2 look goes into ui-new.

- BLE (ESP32): fast advertising (20-30 ms) for 30 s, then 152.5 ms, as the
nRF52 interface; the library default kept 30-60 ms forever
- Live map tiles: the WiFi drops after a minute with nothing missing
- ES8311 to standby while the I2S clocks are off, set up again before the
amp comes on
- Buzzer: no channel (DMA out of memory) waits out the samples instead of
spinning above the UI loop
- OTA: the image header check waits for its 16 bytes
- Comments: P10 is just the LED; the LCD SPI clock is 40 MHz on the wire

The LoRa noise floor with the board's parts off one at a time, sweeps of
850-930 MHz, the mesh channel and a 7.8 kHz zoom on its loudest point; a
slow cycle of the same states for a second radio beside the device; and
a spike hunt over 864-876 MHz listing the lines over the floor and their
spacing (how the I2S MCLK comb was found).
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The speaker's I2S channel was only disabled when idle, which leaves MCLK
running. Its fractional divider (160 MHz / 39 1/16 = 4.096 MHz) makes a
comb of lines every 256 kHz: one at 869.632 MHz, in the EU narrow mesh
channel, lifted the LoRa noise floor from ~-102 to ~-85 dBm, and others
land near GPS L1 and BeiDou B1. The channel is now deleted and its pins
held low after each sound, and made again for the next one. Measured:
noise floor -102 dBm, outdoor first fix 87 s (was 620 s and more).
Also: TCXO at 3.0 V (the L2's part, as Meshtastic has it); GLONASS
enabled on the L76K after each power-up; begin() on a running receiver
no longer resets it (a reset threw away the acquisition in progress).

One .vpk file per region in /vmap (header, sorted index of tiles and
points, then the data), read in place with the index in PSRAM; loose
{dz}/{x}/{y}.vt/.vp files still work. osm_vector.py writes packs

pyosmium) and picks label languages (--lang). Map tools > Vector regions

every 20 m from zoom 15; the credit names the elevation source.

Hiking routes are stored per stretch with the waymark colours of every
route along it and drawn as side-by-side stripes on a white band (half
the route ways in the Tatra sample carry two or more routes), less
simplified; demanding / alpine paths are dotted. Named points (places,
peaks with height, huts, passes, springs, viewpoints, caves) come in
small .vp files and are placed by priority as a layer over the tiles,
clear of each other and of the map controls.

Points as zigzag varint deltas, a byte length per feature to skip it,

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
