The map's download button fetches the visible area (overview levels up to
a chosen zoom) into /sdcard/maps from OpenTopoMap or maps/source.txt,
skipping tiles already on the card and rejecting placeholder answers.
Settings > WiFi stores the network in NVS (with scan); WiFi is on only
while a download runs. HTTP runs on a worker task on core 0; the popup
shows link, internal heap and the last TLS/HTTP error.
Internal RAM was the blocker (~13 KB free with WiFi + Bluedroid): the L2
LVGL env now allocates the_mesh in PSRAM (MESH_IN_PSRAM, static RAM
210 -> 87 KB) and mbedTLS allocates from PSRAM. Confirmed on hardware.

Simulator: SIM_UI=lvgl variants/sim/build_wasm.sh builds ui-lvgl for the
browser. SimLcdDisplay blits LVGL's RGB565 flush to a 320x240 canvas and
LvglPort.h's sim branch feeds the mouse in as touch; LVGL comes from the
L2 env's libdeps, its objects cached in web/build/obj_lvgl/. web/lvgl.html
runs it beside a ui-new peer on a direct link, with a window.sim API for
headless checks. New hooks: sim_lcd_touch, sim_lcd_button,
sim_test_send_channel_msg.
Compose: the theme's padding left less than one line in the field, so it
scrolled vertically and text jumped; pad it to fit exactly one line. The
cursor is drawn only while FOCUSED, now set while the keyboard is up.
With the keyboard up the screen header hides so the conversation keeps a
message in view; the accent popup stays inside the keyboard, clear of the
field; channel bubbles put the age next to the sender (one line shorter);
the thread scrollbar shows only while scrolling.

build_wasm.sh now takes FIRMWARE_VERSION (tag name for a release,
dev-<commit> otherwise) exported by build-solo-sim.yml, so the live demo
no longer falls back to "dev-<compile date>" on tagged releases.

meshcore-solo-site's new cross-visitor relay bridge (Phase 3) needs a way
to read a sim instance's live freq/bw/sf/cr so a WebSocket relay server
can fan traffic out only to other visitors tuned to the same params,
mirroring real LoRa channel isolation. Added sim_radio_get_params()
(examples/companion_radio/main.cpp), reading NodePrefs directly -- the
real live source of truth, since SimRadio::setParams() has always been a
complete no-op (accepts and discards its arguments). Out-params via
pointer, same buffer-pointer idiom sim_radio_poll_tx() already uses;
build_wasm.sh needed HEAPF32/HEAP32 added to EXPORTED_RUNTIME_METHODS so
JS can read them back.
While testing the relay bridge with two independent browser contexts, hit
a real bug: sim_instance_salt() (SimInstance.h) is a pure function of the
simInstanceTag STRING ('hero'/'B'/'R'), so it's only useful for telling
apart same-tab instances -- it's identical for two genuinely different
visitors who both boot a 'hero' instance. Combined with SimRNG::begin()'s
other seed ingredients -- time(NULL) (1-second resolution) and a WASM
heap pointer (no ASLR inside the sandbox, so it's fully deterministic
across independent boots of the same binary) -- two different visitors
landing on the same wall-clock second reliably generated byte-identical
Ed25519 identities (confirmed: two fresh browser contexts launched
together produced provably identical advert packets end to end).
Fixed by mixing in real crypto.getRandomValues()-sourced entropy from the
host page (new sim_instance_entropy(), read the same way simInstanceTag
already is) into both SimRNG::begin() and the twin seeding pattern in
SimRadio::getRngSeed(). Applies to every sim instance uniformly (hero/B/R
all get proper per-session entropy now), not just the new relay path --
strictly an improvement with no compatibility concern, since identity
generation only ever runs once per fresh/empty IDBFS.

- Turn on ENV_INCLUDE_GPS/UI_SENSORS_PAGE for the sim build (both were
compiled out entirely, so the GPS and Sensors home-page carousel
entries didn't exist regardless of home_pages_mask) -- SimSensorManager
already fed a real JS-settable GPS fix and a temperature/battery
channel with nothing to display them.
- Add sim_test_advert_flood() to the repeater build too, mirroring
companion_radio's hook: MyMesh::updateAdvertTimer() otherwise leaves
the repeater's first self-advert 2 minutes out, so a host page
couldn't make it discoverable as a contact (needed for admin login)
right away.

Code-review pass over the buzzer/sim commits turned up several real bugs,
plus two issues found afterward from manual browser testing:
Rendering (SimDisplayDriverCanvas, variants/sim/SimDisplayDriver.h + target.cpp):
- getTextWidth() measured UTF-8 BYTES (strlen()*6), not codepoints. Since
b067e95b stopped stripping accents, any accented string now measures
double its real width -- mis-centred titles, premature ellipsis/marquee,
badges pushed off-screen. Now uses the real MiscFixedRenderer measurement
(miscFixedTextWidth()), same as SH1106Display/SSD1306Display.
- Added the matching getCodepointWidth() override (O(1) single-glyph
advance), same pattern as SSD1306Display.
- isSingleFont() was left at the base class's `false`, though this backend
only ever renders MiscFixed -- UITask.cpp's status-bar indicator height
keys off this (`lh-2` vs `lh`), so the sim drew it 2px taller than a real
board.
- print() blitted the full 128x64 canvas on every call (dozens per frame,
60fps) -- now tracks a dirty bounding box and only clears/blits the
region actually touched.
Web Audio (buzzer bridge, index.html + mesh.html):
- No AudioContext.resume() -- a context created (or later suspended) in the
'suspended' state (Safari/Firefox, or any browser backgrounding the tab)
stayed silent forever. Now resumed on every gesture.
- linearRampToValueAtTime with no anchoring setValueAtTime interpolates
from the LAST scheduled event, not "now" -- so the anti-click ramps could
effectively snap instead of fading. Fixed with cancelScheduledValues +
setValueAtTime(current) before each ramp.
- mesh.html: a gesture only armed the clicked instance's audio. Click A,
send A->B, and B (the one actually meant to beep on receipt) stayed
silent. Now any gesture arms both A and B.
- RTTTL rests (freq=0, still "playing") now explicitly hold pitch and drop
gain instead of it happening to work by coincidence.
Misc: sim_test_get_num_contacts() was missing the g_sim_ready gate every
other sim_test_* hook has, so it could return a bogus negative count before
setup() finishes seeding num_contacts.
Splash screen missing "Solo <version>" bar: variants/sim never defined
FIRMWARE_SOLO_BUILD (every real Solo board does), so SplashScreen silently
skipped that whole line -- the sim looked like a plain non-Solo companion
build. Added -D FIRMWARE_SOLO_BUILD=1 to platformio.ini and build_wasm.sh.
Verified on a real canvas screenshot: "MESHCORE 1.17.1 / 19 Aug 2026 /
Solo v1.27".
Wasm-fetch error message: "failed to start: RuntimeError: Aborted(both
async and sync fetching of the wasm failed)" is Emscripten's own opaque
message for the single most common real cause -- the page opened via
file://...index.html instead of served over http(s) (fetch() on a local
file is blocked by CORS in both Chrome and Safari, confirmed by reproducing
the exact same error/stack via file://). Both harnesses now detect
location.protocol === 'file:' and show an actionable message with the
one-line fix instead of the raw stack trace.
Battery-set latency: SimMainBoard's battery value is an exact, instantaneous
JS-set integer (see sim_battery_set_mv()), but UITask's battery-check code
polls it every 8s and runs it through an EMA (alpha=0.2) meant to smooth a
REAL board's noisy ADC -- so a value typed into the demo UI could take tens
of seconds to visibly settle. SIM_PLATFORM now checks every 250ms and skips
the EMA (nothing to smooth), since the reading is already clean. Measured
on real canvas pixels: indicator update now lands within one screen-refresh
cycle instead of up to 8s+.

genericBuzzer (src/helpers/ui/buzzer.h/.cpp) gets a third platform branch,
#elif defined(SIM_PLATFORM), alongside the existing NRF52 (direct PWM) and
NonBlockingRtttl paths -- purely additive, no changes to either real-hardware
branch. It reuses the NRF52 branch's already hardware-free RTTTL parser
(_parseHeader/_parseNext/_noteFreq, now shared via a widened guard) but
tracks (current frequency, note-end-time) instead of touching real PWM/timer
registers, advancing on plain millis() polling from loop() -- same
non-blocking shape UITask already drives every tick.
Wired into the sim build the same way every real board sets its buzzer pin
(-D PIN_BUZZER=<n> in build_flags/DEFINES; here it's a dummy sentinel since
there's no real pin, just something to activate the existing #ifdef
PIN_BUZZER guards in UITask.h/.cpp/SoundNotifier.h unchanged), plus two new
small UITask accessors (isBuzzerPlaying/buzzerFreqHz/buzzerVolume) and three
EMSCRIPTEN_KEEPALIVE exports so a host page can poll the buzzer's state.
Browser side: one Web Audio oscillator+gain per companion instance (index.html
single-instance; mesh.html per A/B, not R which is headless), created lazily
on the first real user gesture (AudioContext autoplay policy), polled every
20ms and mapped to the oscillator frequency/gain -- so every notification
sound, ringtone, alarm, and volume-blip that already worked on real hardware
now actually produces audio in the browser, unchanged at the call-site level.
Verified end-to-end with real RTTTL playback traces (not just "no errors"):
the startup jingle's exact note frequencies (C6/E6/G6) and a real DM-received
notification triggering the receiving instance's Web Audio gain node from 0
to its mapped volume and back, matching the actual "MsgRcv3" melody's notes.

Two prototype polish fixes ahead of the website embed work:
1. Holding Enter (the sim's main way into "the rest of the options") did
nothing -- the JS bridge's sim_enqueue_key() went straight to
enqueueKey(), bypassing UITask::handleLongPress() entirely, so
KEY_CONTEXT_MENU could never be reached. Add injectSimKeyLongPress()/
sim_enqueue_key_longpress(), which does route through the real
handleLongPress() (same code a real MomentaryButton(pin, 1000, ...)
reaches), and wire up press-and-hold (buttons + Enter/Space key) in both
web harnesses with the same 1000ms threshold real hardware uses.
2. SimDisplayDriverCanvas::print() drew text with the browser's own system
font (ctx.fillText, '8px monospace') instead of the real bitmap font a
MeshCore-Solo board renders with OLED_MISC_FIXED_FONT=1 (see
solo/heltec_v3/platformio.ini). Vendor the real Adafruit_GFX (unmodified,
from the same PlatformIO registry package a real board build pulls) into
variants/sim/thirdparty/gfx/, and render print() through the real,
shared src/helpers/ui/MiscFixedRenderer.h + MiscFixedFont.h -- byte-
identical glyphs to real hardware, not a look-alike.
Verified in a real Chromium (Playwright): short Enter -> "CLOCK TOOLS",
held Enter -> "CLOCK FIELDS" (gotoDashboardConfig(), proving
KEY_CONTEXT_MENU is really reached); font renders as hard square pixels,
inverse/selected-row text still punches correctly through a filled bar.
Full regression re-run clean: all 3 native envs, wasm companion_radio, and
the two-instance + repeater mesh demo (relay routing, DM delivery).

Ports examples/simple_repeater to variants/sim/ (new sim_simple_repeater
native env + build_wasm_repeater.sh) and adds a JS "ether"
(variants/sim/web/mesh.html) that bridges two real companion_radio WASM
instances through a real simple_repeater instance in a strict A<->R<->B
topology (no direct A-B link), proving genuine relay routing rather than
a shortcut.
Also fixes multi-instance issues Phase 2's single-instance design never
surfaced: SimDisplayDriver's canvas context/id caching was keyed on a
single global instead of per-instance, and both wasm builds were missing
_malloc/_free/HEAPU8 runtime exports needed for the ether to poke bytes
into an instance's memory.

New board variant compiling the unmodified MyMesh/UITask/DataStore app
logic against real mesh::Radio/MainBoard/RTCClock/RNG interfaces, for
running the actual firmware outside embedded hardware:
- Native (plain g++, platform = native): ASCII-art display over stdout,
stdin-driven input, local-disk-backed DataStore/IdentityStore.
- Emscripten/WASM (variants/sim/build_wasm.sh, since PlatformIO's native
platform force-overrides any CC/CXX toolchain override back to system
clang++): canvas-backed display, IDBFS-backed persistence across page
reloads, JS-callable input via sim_enqueue_key(), emscripten_set_main_loop.
Real rweather/Crypto (AES128/SHA256/Ed25519) vendored unmodified and
proven working on both targets. variants/sim/web/index.html is a bare
verification harness, not the polished website embed.
