Replaces OSMdroid with MapLibre on the F-Droid flavour, and gives the desktop app a real map for the first time. osmdroid is gone from the version catalog entirely.

Context: #3770 asked for this and was closed as not-planned. This revives it.

Why a new module

feature/map-maplibre rather than source sets inside feature/map, because that module compiles into both Android flavours — MapLibre living there would pull maplibre-native's .so payload into the Play Store build for nothing. Nothing in the google flavour depends on the new module.

The Google flavour is untouched.

What the map does

Everything the OSMdroid map did, plus everything the Google map does that OSMdroid never did:

  • Node markers are real NodeChips — the same rounded, node-coloured badge with the short name in it that the node list and the Google map draw. Emoji short names included, which the OSMdroid map rendered as nothing.
  • Clustering (MapLibre's own, so the OSMdroid clustering code has no counterpart), with a member list when a cluster can't be zoomed apart.
  • Precision circles, waypoints with emoji icons, geofence zones, traceroute paths, a pulse on a node the moment it's heard.
  • Basemaps including user-defined raster tile sources and offline MBTiles, offline area download with a tile/size estimate, imported GeoJSON/KML/KMZ overlays (desktop included — one common layer store, picker and sheet), KMZ ground-overlay draping, Site Planner, the last-heard filters, camera restore.
  • Position tracks that fade from faint to solid in the node's own colour, with a detail card for the point you tap.
  • Discovery scan maps with green/blue chips for direct vs mesh-relayed, sensor/social glyphs, and signal figures on tap.
  • Geofence bounding boxes drawn by tapping two corners on the map.

Parity gaps this closed on the way

Most of the real bugs were the same shape: plumbing that existed and was never connected.

Traceroute legend named colours the map didn't draw TracerouteMapScreen drew its legend from TracerouteColors (orange out, cyan back) while the layers drew blue and green. Route colours now come from that one object.
The discovery map drew no discovered nodes Its camera opened on the scanner at a fixed zoom, so every node it heard was off-screen. It fits their bounds now, once the map reports a viewport.
Refreshing an imported network overlay did nothing A refresh keeps the same URI, so there was nothing for the source to republish. The source is keyed on the refresh token the host already tracks.
Position tracks were unsorted The view model hands positions over newest-first for its list; the map read order as age, so the gradient, the fade and the head chip were all on the wrong end.
KML/KMZ imports were filtered out The file appeared in the layers sheet, could be toggled, drew nothing. Now converted to GeoJSON on the way through.
Imported overlays were painted one flat indigo They now honour simplestyle (fill, stroke, *-opacity, stroke-width) per feature, as the Google flavour does.
A KML opacity was formatted in the device locale "%.3f".format() wrote 0,498 on a comma-decimal phone — invalid JSON, so MapLibre rejected the whole file and every import silently drew nothing.
Discovery drew every node green Saying "heard directly" about mesh-relayed nodes.
EditWaypointDialog's box-authoring button did nothing here The callback existed; this host never passed one, so a geofence could have a radius but never a box.
KeepScreenOn was missing while following the user

Plus: the mini-map had no precision circle and never followed the node; camera fits landed on a degenerate box for a stationary node; the main map's toolbar was the only one not centred; zoom moved from the top toolbar to the lower trailing corner, where Google Maps draws its own.

Verification

64 unit tests over the pure logic — filters, clustering, tile estimates, chip keys, bounding boxes, corner-to-box conversion, and the KML reader (KMZ, nested entries, style maps, unclosed rings, polygon holes, locale, colour byte order).

Beyond that, every surface was driven on an emulator against a simulated radio and photographed: main map, node-detail mini-map, position track (framing, gradient, tap → detail card → list sync), traceroute (legend vs lines, hop chips), discovery (chip colours, glyphs, "You", signal card), KML import (styled polygon, line and point, and a deliberately malformed file logged and skipped), and the two-corner geofence flow end to end.

Self-review pass

After the feature work I went back over this branch adversarially. It turned up four things worth listing, all fixed here:

  • A node past the chip-image ceiling was invisible and untappable — swapping the dot for chips removed the dot, so a capped node resolved to a transparent sprite. The dot is back underneath, and only ever shows when a chip is absent.
  • Refreshing an imported network overlay did nothing, because the URI is unchanged across a refresh and there was nothing to republish.
  • The KML conversion cache claimed to persist and didn't — nothing read the file back, so every navigation reconverted.
  • And the retraction above: a claim that the library freezes GeoJSON sources, which it doesn't.

A second adversarial pass over the finished branch found and fixed five more, all in the tree now: a
network layer's persisted record carries no type, so a GeoJSON layer rehydrated as KML after a restart
and drew nothing; the add-network-layer dialog dropped the store's validation error, so a bad URL closed
it silently; the KMZ readers had lost the 50 MB inflate cap the OSMdroid renderer enforced (a hostile
share-into-app zip could OOM the app); a <description> holding raw non-CDATA HTML aborted the whole
KML import; and the tile estimate went negative for a download box straddling the antimeridian. Plus a
round of smaller polish — the mesh-framing camera jump moved into a proper effect, the per-frame
visibility filter is remembered, and a clustering-parity case where a node already standing alone could
pad a later cluster up to the minimum.

Scale

Tested against a simulated 2500-node DEF CON mesh (2517 nodes, 2479 with positions), since that is roughly what the event actually saw.

It did not hold up at first: chip images were rasterized for the whole node list up to a ceiling, so the budget went to whichever nodes came first and the markers on screen fell back to plain dots. Chips are now drawn only for nodes inside the padded viewport, so the image count is bounded by screen area rather than mesh size — the same handful whether the mesh holds 20 nodes or 2500.

2479 positioned nodes before after
markers on screen plain dots chips
TOTAL PSS 457 MB 334 MB
native heap 122 MB 50 MB

Under a pan-and-zoom stress at that density: 22 ms median frame, 93 ms at the 99th percentile — while also ingesting 120 packets/second, roughly ten times a real mesh's rate. Clustering handles the zoomed-out view.

Known gaps, deliberately

  • The node-detail mini-map does not carry zoom buttons, though the Google one does: ours is a floating toolbar nearly 100dp tall on a ~160dp thumbnail. It pinch-zooms.
  • Chips can overlap where two nodes sit close, exactly as they do on the Google map. At DEF CON density that is common when zoomed in past the clustering threshold.
  • iOS targets compile but there is no iOS map host.

Flatpak build plumbing

The desktop map pulls a per-arch native runtime, which broke the arm64 Flatpak twice on this branch:
the offline manifest is generated on x86_64, so anything the two arches resolve differently has to be
force-resolved during generation.

  • The maplibre runtimes and desktop-jvm read their versions from the version catalog. The block's
    own comment said that wasn't possible; the generated libs accessor genuinely doesn't resolve in the
    root script, but VersionCatalogsExtension does. The maplibre entries name the same catalog aliases
    desktopApp uses, so the two can't disagree, and a target platform with no catalog entry now fails at
    configure time. This also closes a live bug: the block sat at compose-multiplatform 1.11.1 long after
    the catalog moved to 1.12.0-rc01.
  • Since flatpak-sources 0.2.0 every declared coordinate resolves transitively, so skiko,
    maplibre-native-ffi and the LWJGL natives need no hand-tracked entries at all — desktop-jvm and the
    maplibre runtimes bring them along. What transitive resolution cannot supply is a root: a per-arch
    runtime desktopApp resolves that nothing declares has nothing to expand from, and the miss surfaces
    as Could not find <jar> eleven minutes into the arm64 build — exactly how the maplibre runtime was
    missed here. scripts/verify-flatpak/check-platform-deps.py guards that root: fully offline, it
    cross-checks the build scripts against the catalog and fails on an undeclared per-arch runtime or a
    version restated as a literal.
  • It runs in check-metadata, not verify-flatpak.yml: that workflow's path filter excludes
    gradle/libs.versions.toml, so a dependency bump — the thing that causes this drift — would never
    have triggered it.

Tile sources, and three issues closed

The tile catalogue — URL templates, zoom ranges, attribution — lived in the MapLibre module, which only the
F-Droid flavour reaches, and the custom-source editor and its store lived in androidApp. So the Google map
offered Google's four map types and nothing else, and adding a source at all was Android-only. Both now live in
feature/map, the one map module both flavours and the desktop app depend on.

  • Closes [Bug]: Custom tile sources (such as opentopo) do not buffer #2714 — custom tile sources don't buffer, wiping the map while scrolling. Google's UrlTileProvider
    opens a bare stream per tile and keeps nothing, so panning re-downloads what was just on screen. Tiles now go
    through OkHttp with a 64 MB disk cache; a server that states no cache policy gets a conservative one-hour
    default, which covers the hand-typed sources that prompted the report. MapLibre caches in the renderer, so the
    F-Droid and desktop maps were already covered by the engine swap.
  • Closes [Feature Request]: Allow user to add custom geo-layer sources (Satellite / Topo) #5806 — add Swiss topo and satellite layers. Answered generally rather than by shipping two national
    endpoints: custom sources now work on desktop too — the store, the editor and the validator are common code, so
    any provider's endpoint can be added by whoever needs it, on either engine. (The iOS targets compile it and run
    its tests; no iOS map surface consumes it yet.) Verified end to end on the desktop app with the requester's own layer —
    https://wmts.geo.admin.ch/1.0.0/ch.swisstopo.pixelkarte-farbe/default/current/3857/{z}/{x}/{y}.jpeg added,
    selected, persisted, and removed. (The imagery layer is the same URL with ch.swisstopo.swissimage.)
  • Closes Meshtastic Desktop: Map is not visible #6592 — desktop map not visible on 2.8.0. This branch is what puts a map on the desktop app at all.
    Verified on macOS against a simulated radio; the Linux rendering path is untested here.

Google also gains the six raster basemaps and the NOAA radar overlay from the shared catalogue, and now credits
its tiles: OpenStreetMap's and Esri's policies both require displayed attribution and an identifying User-Agent,
neither of which survived the move off OSMdroid's tile sources. Hillshade stays MapLibre-only — its pixels encode
elevation for a renderer that shades them into terrain, and Google would composite the raw values as noise.

Two fixes found on the way: the Google flavour stored the file picker's raw content:// URI as an MBTiles
location, which no File resolves, so local archives there silently drew nothing; and the NOAA radar overlay
pointed at a host that has been NXDOMAIN for about a year, inherited from OSMdroid on main.

One KML path, and it draws icons now

The KML reader was Android-only (XmlPullParser), so the desktop app could not open a KML at all, and the
Google flavour ran a second, unrelated parser from maps-utils. It is one converter now — KmlToGeoJson in
feature/map/commonMain, on xmlutil — and both flavours plus desktop read through it.

That merge was only safe once icons worked, because maps-utils drew them and this converter did not:

  • The converter reads a placemark's <IconStyle><Icon><href> into an icon-url property. This is an
    extension, deliberately: simplestyle-spec defines marker-symbol over the maki vocabulary and has no
    arbitrary icon-URL field, and no later spec has added one — the modern answer is layer-level styling, which
    is what the MapLibre renderer does anyway. So the property is ours, and documented as ours.
  • The Google map keeps resolving them, including a KMZ's packed images, which the shared path now
    extracts rather than discarding.
  • The MapLibre map draws them for the first time. It cannot discover them for itself — MapLibre picks an icon
    per feature from a fixed set of style images and ImageManager's acquire methods are library-internal, so
    nothing can register a bitmap under a name chosen later. The host scans the finished GeoJSON once and hands
    the layer the set, which also covers an imported GeoJSON that names its own icons.

Two RFC 7946 conformance fixes came out of reading the spec rather than assuming it:

  • §3.1.9, antimeridian cutting. A geometry crossing 180° must be split. It wasn't, so an imported track
    across the Pacific drew as a line straight back across the whole world.
  • §3.1.6, the right-hand rule. Exterior rings MUST wind counterclockwise; we only closed them.

JSON-FG (adopted May 2026) needed nothing — it is a backward-compatible extension, so valid JSON-FG already
imports. KML 2.3 likewise: it adds Tour and Track, which nothing exports.

KMZ ground overlays drape now, on both maps — closes #3786. The converter reads <GroundOverlay>
beside the placemarks (an overlay-only document is no longer "nothing mappable"), the corner math applies the
optional <rotation> (CCW about the centre, in a locally-scaled frame so boxes don't shear with latitude) and
is unit-tested beside the parser. MapLibre drapes an ImageSource quad under a RasterLayer, images extracted
into the conversion cache with a corner sidecar; Google drapes GroundOverlayOptions from bounds with
bearing = -rotation, images from the same packed-image map its icons use. Verified with a hand-built KMZ on
desktop and the F-Droid emulator: the image drapes right side up exactly inside its box, with a placemark from
the same file pinned to its top-left corner. The Google flavour imports the same KMZ and runs its drape path clean. With the CI debug Maps key
injected locally (google.properties, the same mechanism the snapshot workflow uses), the rotated case
is verified on both renderers: a 90° corner-coloured test KMZ drapes identically on the Google and
F-Droid emulators, every corner exactly where the tested corner math puts it — so the bearing = -rotation sign conversion is confirmed, not just reasoned.

Known gap: an icon'd point keeps the plain circle underneath it, which can show through a transparent
icon. Narrowing the circle layer's filter to exclude icon-bearing features was tried and backed out — the
filter change could not be verified against a mixed layer on the emulator, and shipping it unverified risked
dropping every plain point from view for a cosmetic gain.

Site Planner on desktop

Desktop had no Site Planner because there was no embedded browser. The pinned JBR toolchain does resolve to
a JCEF build, but jlink strips CEF out of the packaged runtime — measured: bundling Chromium takes the app
from 218 MB to ~757 MB per platform. Desktop hands the planner to the system browser instead: same URL, same
location seeding, no host bridge requested where no host provides one.

The estimate comes back by hand, and desktop can now receive it: the whole imported-layer feature moved to
common code and desktop mounts the same layers sheet
— store and persistence in feature/map (Okio files,
Ktor network layers, expect/actual storage dirs beside the desktop database in ~/.meshtastic), the picker
expect/actual in the ExportSaver mould (SAF on Android, AWT FileDialog on desktop), and the KML→GeoJSON
conversion host shared by the F-Droid and desktop maps. The sheet's note tells the user to use the planner's
Export › GeoJSON (its KML export is a <GroundOverlay> whose image arrives as a sibling file no importer
can reach — a KMZ export upstream would close that). Byte-compatibility was deliberate: file URIs match
Android's Uri.fromFile exactly, because a layer's URI string keys its hidden/shown state, and drift would
un-hide every layer on upgrade. Along the way the "Send to App" share now lands on F-Droid too (the old
one-slot bus only reached the Google map), and network KML layers on MapLibre are no longer read through a
ContentResolver that cannot open http — the store fetches them itself. (The old path demonstrably drew
nothing; the new one has not been exercised against a live URL.)

What desktop still cannot do is receive the estimate automatically — that JavaScript bridge needs the
embedded browser this section starts with.

Also fixed here: offline pack downloads are gated on offlineMapsSupported. The MapLibre offline API
compiles on desktop and silently downloads nothing, so the desktop UI offered a download that created an
empty pack.

Note for reviewers

maplibre-compose 0.15.0 has a bug worth knowing about: ImageManager.acquirePainter computes toSdf(), stores it in a map nothing reads, and uploads the unconverted bitmap while telling MapLibre to read it as an SDF. Present on upstream main; not yet reported. Nothing here uses drawAsSdf, and there's a comment in NodeChipLayer saying why.

That aside, the library behaves: an earlier commit on this branch claimed rememberGeoJsonSource freezes its data and wrapped every source to work around it. It does not — 0.15.0 republishes on change — and the wrapper's manual setData has been removed. The claim is retracted in 196119928 rather than left in the tree, because it would have sent a reviewer looking for a bug that isn't there.

Merge Risk: 🟠 High · up to 1c409

This change adds new map import and offline-download behavior, but an imported filename can currently escape the intended storage directory, large files can freeze the app during copying, and offline downloads may remain paused after starting. Several malformed or incomplete location and overlay inputs can also produce incorrect map data, so the PR is not merge-ready until these issues are addressed.

Full details: Sibling Call Sites And Presence Semantics

Explanation

No explicit sibling-call-site or physical-metric presence failure was introduced. The PR does not change NodeItem.kt, NodeItemCompact.kt, EnvironmentMetrics, or DiscoveryMapNode declarations. Both node-item siblings already use nullable temperature presence, and NodeItemZeroMetricsTest covers zero and absent temperature for both. The new MapControlsOverlay nullable callbacks have all five call sites updated, using named arguments; the new MapLibre secondary-map call also passes null intentionally. Existing DiscoveryMapNode.snr: Float = 0f is unchanged and is not a new field introduced by this PR.

Full details: Tests Prove The Path, Not The End State

Explanation

Two added tests assert only collection counts and do not identify the surviving items. MapLibreMapTest.kt:190-193 checks only collection.features.size == 1, so an implementation that drops the located node and keeps the unlocated node can pass. KmlToGeoJsonTest.kt:240-255 checks only that three Feature strings exist, so the converter can emit three incorrect features and still pass. The changed tests contain no fake backing-store seeding and no Dispatchers.Unconfined emission-order assertions.

Resolution

Strengthen MapLibreMapTest by extracting NodeFeatureKeys.NODE_NUM from the feature properties and asserting that the surviving ID is exactly 2. Strengthen the KML multi-placemark test by asserting the exact feature geometries or parsed feature list, including the two point coordinates and the line coordinates/type, instead of only counting "type":"Feature" occurrences. Retain count assertions only as supplementary checks.

Full details: Regression Coverage For Changed Behavior

Explanation

The PR adds substantial map behavior, but coverage is limited to pure geometry/registry tests and KML conversion tests. The following changed paths have no regression test that exercises their observable behavior: 1. Camera restore and zoom controlsrememberRestoredCamera reads and writes MapPrefs around Compose camera state (CameraPersistence.kt:43-75), and zoomBy drives the new zoom buttons (MapCamera.kt:28-31, ZoomControls.kt). The observable surfaces are DataStore preferences and Compose UI. A race can overwrite a saved camera before restore, and boundary presses can exceed a basemap range or animate unnecessarily. The added screenshot only renders MapZoomControlsPreview; it does not click the controls. Add a Compose test with a delayed fake MapPrefs that verifies no early write, saved-camera restoration, settled-camera writes, and deduplication. Add a camera test for positive/negative deltas, both range limits, and no animation at a limit. 2. Basemap preference and MBTiles wiringrememberBasemapSelection writes either the built-in index or the custom-provider ID (BasemapSelection.kt:66-47), while customRasterBasemaps and importMbTiles resolve and copy local archives (CustomRasterBasemaps.kt:37-70, MbTilesImport.kt:39-56). The observable surfaces are persisted map preferences, provider state, and Android file/URI handling. There is no test for custom selection surviving recomposition/reload, missing local archives being omitted, blank remote URLs being omitted, successful content:// copying, null streams, or copy failures. Add Robolectric tests with fake preferences and a fake ContentResolver, including the missing-file case that must avoid producing an mbtiles:// source. 3. KML layer conversion lifecyclerememberRenderableLayers and convertKmlLayer add visibility filtering, refresh-token cache keys, cross-session file reuse, and .part/rename handling (ConvertedKmlLayers.kt:47-105). The existing KmlToGeoJsonTest covers only the converter. The observable surfaces are Compose layer state and cached files. A visibility toggle can reconvert unnecessarily, a refresh can retain stale data, or a failed conversion can leave a trusted partial file. Add a test using a temporary cache and fake content resolver that verifies non-KML passthrough, conversion completion, cache reuse, refresh-token invalidation, malformed-input omission, and partial-file behavior. 4. GeoJSON projections used by map layersprecisionCirclesToFeatureCollection, waypointsToFeatureCollection, geofencesToFeatureCollection, and routeToFeatureCollection feed the visible layers (GeoCircle.kt:60-75, WaypointFeatures.kt:48-90, TracerouteLayers.kt:45-59). The observable surface is map rendering. Current tests cover the precision lookup, one circle ring, and node features, but not these feature collections. Add common tests that verify degraded versus full-precision nodes, feature properties, invalid waypoint coordinates, icon code-point fallback and surrogate pairs, locked waypoint state, closed circle/box geometry, and route order with missing hops skipped. 5. Waypoint editing and deletion state machineWaypointDialogs, rememberWaypointEditing, DeleteWaypointDialog, and WaypointInfoDialog now gate actions on connection and lock state and implement two-tap box authoring (WaypointDialogs.kt:25-80, 136-235, DeleteWaypointDialog.kt:49-55). The observable surfaces are Compose UI and mesh waypoint operations. The existing boundingBoxFromCorners test does not exercise the state machine. Add Compose tests for connected and disconnected long-press placement, locked and unlocked edit/delete visibility, local versus broadcast deletion, alert opt-in, duplicate-corner rejection, second-corner commit, cancel/reopen, and visible-region commit. 6. Main and secondary map interactionsNodeLayers adds cluster expansion/member selection and th… [truncated to fit comment limits]

Resolution

Add the tests described in all eight findings. Keep the existing pure tests, but add stateful Compose, Android URI/file, offline-manager, F-Droid, and desktop/JVM coverage. Ensure each regression test fails when the corresponding changed implementation is reverted, and run the new module tests plus the F-Droid and desktop build/test configurations in CI.

Full details: Moved Code Diffed Against Its Original

Explanation

The KML overlay move changed the cancellation exception contract. The old FdroidMapOverlayRenderer.parse explicitly rethrew CancellationException (base revision lines 158–161), so LaunchedEffect(mapLayers) could cancel an obsolete parse. The new KmlToGeoJson.convert wraps parsing in runCatching and returns an empty feature list, and convertKmlLayer wraps the full conversion in another runCatching and returns null (KmlToGeoJson.kt:54–56, ConvertedKmlLayers.kt:82–105). Both runCatching blocks catch CancellationException. The new caller still runs conversion from LaunchedEffect(conversionKey) (ConvertedKmlLayers.kt:55–60), so a layer refresh or visibility change can be treated as a conversion failure instead of cancellation and can continue stale work.

Resolution

Preserve coroutine cancellation in the new KML path. Catch and rethrow CancellationException before handling ordinary exceptions in both KmlToGeoJson.convert and convertKmlLayer; log and return the empty/null result only for non-cancellation failures. This keeps LaunchedEffect(conversionKey) cancellation behavior equivalent to the old LaunchedEffect(mapLayers) path.

187-199: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick win

FrameOnce writes state and launches a coroutine during composition.

Lines 195-196 run inside the composition pass: they set hasFramed.value and start a camera animation with scope.launch. Compose can run or abandon a composition without committing it, so the camera jump can fire for a composition that is never applied, and the state write forces an extra recomposition. Move the effect into LaunchedEffect so it runs only after a successful composition.

Inline comments:
In `@androidApp/src/fdroid/kotlin/org/meshtastic/app/map/ConvertedKmlLayers.kt`:
- Around line 82-105: Update convertKmlLayer to use
org.meshtastic.core.common.util.safeCatching instead of runCatching, preserving
the existing failure logging and nullable result behavior while ensuring
CancellationException is rethrown rather than converted to null by getOrNull().

In `@androidApp/src/fdroid/kotlin/org/meshtastic/app/map/KmlGeoJson.kt`:
- Around line 47-49: Update parseCoordinates to require both parsed longitude
and latitude to be finite using Double.isFinite() before constructing the
GeoJSON coordinate string; return null for NaN or Infinity values.

In `@androidApp/src/fdroid/kotlin/org/meshtastic/app/map/KmlReader.kt`:
- Line 43: Update
androidApp/src/fdroid/kotlin/org/meshtastic/app/map/KmlReader.kt:43 so id-less
Style elements are still parsed; in KmlReader.kt:130-146, capture nested inline
Style elements on the current Placemark; and in
androidApp/src/fdroid/kotlin/org/meshtastic/app/map/KmlToGeoJson.kt:112-115,
resolve the Placemark’s inline style before its shared styleUrl style so inline
styling takes precedence.

In `@androidApp/src/fdroid/kotlin/org/meshtastic/app/map/node/NodeMapScreen.kt`:
- Around line 49-53: Update the MapLibreNodeTrackMap call in NodeMapScreen so a
null node does not produce destNum 0; preserve the absent destination value
through the map contract or render the map only after node is available, while
keeping the existing behavior for a non-null node.

In `@androidApp/src/main/kotlin/org/meshtastic/app/map/MbTilesImport.kt`:
- Around line 39-53: Update importMbTiles to execute the blocking URI open,
directory creation, and file copy inside withContext(ioDispatcher), using the
injected CoroutineDispatchers configuration rather than a direct dispatcher
reference. Extend its failure handling to catch SecurityException from
contentResolver.openInputStream and return null with appropriate logging,
preserving the existing IOException behavior and KDoc contract.
- Around line 45-48: Sanitize or validate fileName before constructing target in
the MBTiles import flow: prevent path separators and traversal so the resolved
destination remains inside MBTILES_DIR. Preserve the existing copy behavior only
for safe filenames.

In `@docs/en/user/map-and-waypoints.md`:
- Line 95: Update the KML/KMZ availability statements in the map-layer
documentation, including the sections around the layer import description and
Map Sources, to identify the rendering limitation as desktop-only rather than
applying it to F-Droid. Preserve the documented F-Droid KML/KMZ import path
through rememberRenderableLayers and keep offline-download availability
documented separately.

In
`@feature/map-maplibre/src/commonMain/kotlin/org/meshtastic/feature/map/maplibre/component/ClusterMembersDialog.kt`:
- Around line 72-73: Update ClusterMemberRow to enforce a minimum 44.dp
touch-target height on its clickable Column, while preserving the existing
width, click behavior, and padding.

In
`@feature/map-maplibre/src/commonMain/kotlin/org/meshtastic/feature/map/maplibre/component/OfflineMapTarget.kt`:
- Around line 160-164: Move all offline-map labels in OfflineMapTarget,
including tile counts, “Tile limit reached,” and zoom-range text, into shared
localized string resources. Define resource templates with placeholders and pass
formatted numeric values through stringResource instead of concatenating raw
English text. Update both the shown label and the additional range around lines
256–282 while preserving the existing values and display behavior.
- Around line 242-253: Update the OfflineManager.create flow in the surrounding
offline-pack creation function to capture the returned OfflinePack, call resume
on it before reporting success, and preserve the existing failure logging and
success result behavior.

In
`@feature/map-maplibre/src/commonMain/kotlin/org/meshtastic/feature/map/maplibre/geojson/NodeFeatures.kt`:
- Line 80: Update the PRECISION_METERS assignment in NodeFeatures so a null
result from precisionMeters is preserved or the property is omitted, instead of
using 0.0 as a fallback; keep numeric precision values unchanged.

In
`@feature/map-maplibre/src/commonMain/kotlin/org/meshtastic/feature/map/maplibre/geojson/WaypointFeatures.kt`:
- Around line 52-54: Update the waypoint mapping logic around latitude_i and
longitude_i to require both nullable coordinates before applying DEG_SCALE;
return null when either is absent, and preserve the existing zero-coordinate
filtering for present values.
- Around line 69-81: Update iconGlyph and appendCodePointCompat to accept only
valid Unicode scalar values: non-negative values up to 0x10FFFF that are not
within the surrogate range 0xD800–0xDFFF. Return the default pin for invalid or
zero values, and preserve the existing character construction for valid nonzero
code points.

In
`@feature/map-maplibre/src/commonMain/kotlin/org/meshtastic/feature/map/maplibre/NodeTrackMap.kt`:
- Around line 177-179: Update the TrackPointCard invocation so it is rendered
only when selectedPositionTime is non-null, preventing firstOrNull from matching
a ProtoPosition with a null time when no position is selected.
- Around line 189-196: Update ProtoPosition.toTrackPoint() to return null
whenever latitude_i or longitude_i is absent, before applying DEG_SCALE or
constructing GeoPosition; do not substitute missing coordinates with zero.
Preserve the existing zero-coordinate rejection for explicitly reported values
if required by the surrounding behavior.

In
`@feature/map-maplibre/src/commonMain/kotlin/org/meshtastic/feature/map/maplibre/style/Basemaps.kt`:
- Around line 68-74: Move the hardcoded menu labels to shared string resources
so they can be localized: update the Liberty, Positron, and Dark entries in
feature/map-maplibre/src/commonMain/kotlin/org/meshtastic/feature/map/maplibre/style/Basemaps.kt
(lines 68-74), and the Hillshade (65-76), Weather radar (84-101), and
Precipitation (113-129) entries in
feature/map-maplibre/src/commonMain/kotlin/org/meshtastic/feature/map/maplibre/style/MapOverlays.kt
to use the appropriate shared resource identifiers instead of literal label
text.

…ode GeoJSON

Adds :feature:map-maplibre, a KMP (android + jvm) module that will back the
F-Droid flavor and the desktop app. Kept out of :feature:map deliberately —
that module compiles into both Android flavors, so MapLibre there would drag
maplibre-native's .so payload into the Play Store build.

Registries carry the OSMdroid tile sources over 1:1 (OSM, OpenTopo, USGS
topo/imagery, Esri topo/imagery, NOAA radar via {bbox-epsg-3857}) and add the
OpenFreeMap vector styles plus a Terrarium-encoded hillshade — terrain being
what actually explains a failed LoRa link.

:feature:map gains a jvm target and MapScreen moves to commonMain so desktop
can render it; the waypoint dialogs stay on androidMain until their
DatePickerDialog use is replaced.
… MapLibre

Node clustering, cluster expansion and the point_count aggregation now come
from MapLibre's own GeoJSON source rather than hand-rolled overlay code.

Precision circles and geofence zones are emitted as real ground polygons: a
MapLibre circle radius is screen-space, so drawing them as circles would have
made a node's claimed accuracy change every time the user zoomed.
The five map seams keep their existing names and packages, so MainActivity's
composition-local wiring is untouched; only their bodies change.

Removes osmdroid, osmbonuspack and geopackage along with ~4k lines of overlay,
tile-source, clustering and cache-writer code. The osmdroid user-agent hook
becomes a no-op — maplibre-native runs its own HTTP stack.

Offline tile packs, custom tile providers and the map-embedded layer sheet are
not yet re-wired; they lived inside the deleted MapView and need MapLibre's
OfflineManager instead of the OSMdroid cache writer.
…ests

Desktop had no map at all — the tab was a placeholder because the module had no
map library. It now shares every surface with the F-Droid flavor.

Tests target the parts that fail silently: the Terrarium DEM encoding, the WMS
bbox placeholder, the precision-circle table carried over from OSMdroid, and
the bounding-box helper that used to let an empty node list frame (0, 0).
…e swap

A spatial-k Position is itself a coordinate collection, so closing a circle
with `ring + ring.first()` bound to the Iterable overload of plus and quietly
flattened the appended point into loose doubles.

CameraState has no jumpTo(CameraPosition) — only the bounding-box form plus a
settable position. Material icons are not a dependency in this project, so the
menus use material3 selection controls instead.

Also extracts the shared colour palette, splits the two oversized composables,
and captures the mappable-count callback so a recomposition cannot fire a
stale one from inside the effect.
… swap

Imported overlays reach the shared module already reduced to GeoJSON, so it
never touches the filesystem — the host resolves files, network URLs and
archives. One source feeds fill, line and circle layers because a single
import can mix polygon, line and point geometry.

Documents the new base map and overlay pickers, marks the desktop map as
shipping, and states plainly that offline tile downloads and KML/KMZ import
are unavailable on these two targets until they are rebuilt on MapLibre.
Running the app surfaced two things compiling could not.

The Map tab rendered its placeholder because mapGraph resolves the screen
through LocalMapMainScreenProvider, a sixth seam separate from
LocalMapViewProvider; desktop only provided the latter. MapScreen already moved
to commonMain, so desktop now takes the same path Android does.

The basemap and overlay pickers rendered their menu items inline, unanchored,
because MapControlsOverlay's slots expect a button plus its own dropdown rather
than bare items. Both slots now follow that contract, and the filter slot —
previously an empty lambda, so the filter button did nothing — carries the
favourites, waypoints and precision-circle toggles.
Every SymbolLayer left textFont unset, so MapLibre fell back to the style-spec
default of "Open Sans Regular, Arial Unicode MS Regular". OpenFreeMap serves only
Noto Sans, so every glyph request 404'd:

    The resource `https://tiles.openfreemap.org/fonts/
      Open%20Sans%20Regular%2cArial%20Unicode%20MS%20Regular/0-255.pbf` not found
    Failed to load glyph range 0-255 for font stack
      Open Sans Regular,Arial Unicode MS Regular:( HTTP status code 404)

A symbol layer with no glyphs draws nothing, silently — node short names, cluster
counts and waypoint labels were all simply absent, with nothing on screen to say why.

Ask for "Noto Sans Regular", which the style's own layers use. Verified against a
running desktop app: five glyph 404s before, none after, and labels now render.

Caveat on waypoint-icon: it renders an emoji through textField, and OpenFreeMap
publishes no emoji font, so naming a real stack stops the 404 but will not make
emoji glyphs appear. Rendering those needs an image-based icon layer instead.

…s at all

On 0.14.0 nothing composed inside MaplibreMap ever appeared on the desktop
renderer except a single layer. Every other layer logged as inserted and then drew
nothing — node circles, cluster bubbles, geofences, and the raster overlays alike:

    Initializing anchor Top with layer node-chip-label
    Adding layer node-clusters below node-chip-label      <- never drawn
    Adding layer node-chip     below node-chip-label      <- never drawn

Narrowed by elimination against a live app: the data reached the source (59
features), the filters passed, the camera framed the mesh, and a layer on an
unclustered source with a constant colour drew correctly. Removing the filter did
not help; removing clustering did not help; the feature-derived colour expressions
were fine. What the invisible layers shared was being inserted relative to the
anchor rather than being the anchor.

0.15.0 fixes it — "Overlapping style loads no longer leave a stale style". The
eleven "Attempting to call removeLayer/removeSource on an unloaded style" warnings
0.14.0 emitted are gone, and on a clean start every layer draws.

Two API changes come with it:

  - getClusterExpansionZoom is now suspend (feature queries no longer block the
    caller), so the cluster tap launches instead of calling inline.
  - rememberAwtComposeGpuHost is renamed rememberAwtComposeMapHost, and
    MapLibre.configure() is optional — the first map applies a default cache
    configuration, so the process-wide setup in Main.kt goes away.

NOT YET DONE — this only covers desktop. 0.15.0 moved Android and iOS onto the same
MapLibre Native FFI stack, so the F-Droid Android flavour still needs a render
runtime (maplibre-compose-runtime-vulkan-android or -opengl-android; the MapLibre
Android SDK is no longer transitive), minSdk 24, compileSdk 37, and the removal of
OrnamentOptions. Do not merge before that lands.

…quires

0.15.0 moved Android onto the same maplibre-native FFI stack desktop already used,
so the MapLibre Android SDK is no longer pulled in transitively and a render backend
has to be named explicitly. Without one the F-Droid flavour builds and then has
nothing to draw with.

OpenGL ES rather than Vulkan: it is what the pre-0.15 Android SDK rendered with, and
every device MIN_SDK=26 reaches has it, whereas the Vulkan backend needs a working
Vulkan 1.0 driver. Swapping to -vulkan-android is a one-line change if we want it.

runtimeOnly on androidMain — nothing compiles against the backend, it only has to
reach the APK. Verified in androidApp-fdroid-arm64-v8a-debug.apk:

    lib/arm64-v8a/libmaplibre-native-c.so     13047112
    lib/arm64-v8a/libjniMaplibreNativeC.so     1183264

and confirmed it stays out of the Play build, which this module must never reach:
`dependencyInsight --configuration googleDebugRuntimeClasspath --dependency maplibre`
reports no matching dependencies.

The rest of the 0.15.0 Android requirements were already met: MIN_SDK=26 clears the
new floor of 24, COMPILE_SDK=37 matches, and OrnamentOptions was never used.

MapControlsOverlay already accepted bearing, onCompassClick, followPhoneBearing,
isLocationTrackingEnabled and onToggleLocationTracking, but the MapLibre provider
passed none of them — so two of the five toolbar buttons were decorative, while the
Google flavour has had both since it shipped.

Wires them with maplibre-compose 0.15.0's location API, which added location on every
platform:

  - rememberLocationState drives collection, gated on the user's own toggle. It never
    requests permission by itself, so opening the map still prompts for nothing.
  - LocationPuck draws position, accuracy and heading, themed via the material3
    LocationPuckDefaults.colors(). Declared last so the user sits above the mesh.
  - LocationTrackingEffect + updateCamera follow the fix, with BearingUpdate
    TRACK_ORIENTATION when heading-lock is on and IGNORE otherwise — so a user who has
    rotated the map is not straightened out behind their back.

Deliberately GMS-free: rememberDefaultLocationProvider, not
rememberFusedLocationProvider. Fused location needs play-services-location, which must
never enter an F-Droid build; 0.15.0 moved it behind the separate location-runtime-gms
artifact, leaving the default provider dependency-free. Desktop is covered by
location-runtime-macos, already on its runtime classpath.

Behaviour matches the Google flavour deliberately: the compass toggles heading-lock
while following and otherwise straightens to north; turning tracking off also drops
heading-lock; a permanently denied permission opens app settings via
rememberSystemSettingsLauncher rather than prompting into a void. Both the camera
effect and the puck are gated on the toggle, so switching tracking off leaves no stale
dot behind.

MapView was extracted into rememberLocationControls plus FilterMenu, BasemapMenu and
OverlayMenu along the way. That clears the pre-existing detekt LongMethod violation on
this file (96 lines, which this change would otherwise have pushed to 142) — the module
now passes detekt cleanly.

Waypoints were read-only here. WaypointLayers already reported taps and MeshMap
already threaded onWaypointClick through, but the provider never passed it, so the
callback defaulted to {} and every tap was dropped. The waypointId deep link the
navigation graph hands to MapView was likewise ignored — following a waypoint link
opened the map and then showed nothing.

Wires both: a tap (or a deep link) opens WaypointInfoDialog, which offers geofence
alert opt-in and, for unlocked waypoints, deletion through DeleteWaypointDialog with
the same delete-for-me / delete-for-everyone split the Google flavour has. Deleting
for everyone re-broadcasts an expiry, so it stays gated on a live connection.

WaypointInfoDialog and DeleteWaypointDialog moved from androidMain to commonMain to
make this possible. Neither had a single android.* or java.* import — they were
already multiplatform, just filed in an Android-only source set, which is what kept
them out of reach of the shared MapLibre module and therefore out of reach of desktop.
Their preview files stay in androidMain, since PreviewLightDark is Android-only.

Still missing, and tracked separately: creating and editing waypoints. That needs
EditWaypointDialog, which genuinely is Android-bound — it drives
android.app.DatePickerDialog and android.widget.TimePicker, so moving it means
replacing those with Compose Multiplatform date and time pickers in a dialog the
shipping Google flavour also uses.

MapView was over detekt's method-length limit again after this, so the dialogs live in
their own WaypointDialogs composable that owns the deletion step itself.

Tapping a cluster always zoomed to its expansion zoom, clamped so a cluster that
reports the no-expansion sentinel never zoomed out. That left co-located nodes
unreachable: they cluster at every zoom, so the tap did nothing and there was no way
to get at the nodes underneath. The Google flavour answers a cluster tap with a list
of the nodes in it.

Now the two cases are distinguished. A cluster that can still be broken apart zooms,
exactly as before. One that cannot — the sentinel case, meaning the nodes share a
position — lists its members instead, and picking one opens that node. Which is what
the existing `nodes_at_this_location` string has always described, so this adds no
new resources for Crowdin to carry.

Members are read with GeoJsonSource.getClusterLeaves (suspend as of 0.15.0, like the
expansion-zoom query). Names come off the leaf features' own properties, which
nodesToFeatureCollection already writes, so listing a cluster costs no lookup against
the node database.

ClusterMembersDialog is local to this module rather than shared: the Google flavour's
ClusterItemsListDialog has no android.* imports and would otherwise have been movable,
but it is typed against NodeClusterItem, a Google-Maps-specific cluster item. Unifying
the two behind a neutral model is worth doing separately.

The MapLibre map offered only its nine built-in basemaps. The Google flavour lets the
user add their own XYZ tile endpoints and pick between them, which the OSMdroid map
did before it — a real expectation for F-Droid users with their own or offline-ish
tile servers.

The store was already multiplatform: MapTileProviderPrefs, with customTileProviders
and selectedCustomTileProviderId, has been sitting in core/repository all along. So
the shared map module needed no new persistence — it now reads that pref and honours
it.

Selection stays two-part, matching how the Google flavour stores it: an index into
the built-in list, plus a separate id for a user-defined source. A single index over
a merged list would silently repoint the user's built-in choice whenever a custom
source was added or removed.

The sources themselves come from the host, the same way customLayers already does:
MapLibreMapViewProvider gains customBasemaps and a basemapMenuExtra slot at the foot
of the basemap menu. The F-Droid app fills both — it maps its stored configs to
Basemap.Raster and puts the existing CustomTileProviderManager editor behind a menu
item. Desktop supplies neither and behaves exactly as before.

Deliberately not the obvious refactor: CustomTileProviderConfig and its repository
look like they belong in core, but the config imports java.net.URI for tile-template
validation, and commonMain forbids java.*. Moving them means rewriting that
validation on a multiplatform URL parser — worth doing, but not as a side effect of
this, and the host-supplies-it seam this module already uses avoids needing it at all.

Local (MBTiles) sources are filtered out for now: MapLibre wants a URL template it
can fetch, and serving it a local file is separate work.

Completes waypoint parity. Details and deletion landed in aa23d13; creating and
editing did not, because the only editor that exists — EditWaypointDialog — drives
android.app.DatePickerDialog and android.widget.TimePicker for the expiry picker and
so cannot live in a source set shared with desktop.

Rather than rewrite a 540-line dialog the shipping Google flavour also uses onto
experimental Compose pickers — a visible UX change that deserves its own review under
constitution V — the editor is supplied by the host, the third use of the seam this
module already had for customLayers and custom basemaps. The F-Droid flavour passes
EditWaypointDialog; desktop passes nothing and simply cannot create waypoints, as
before.

Everything except the dialog stays shared. MaplibreMap's onMapLongClick places a new
waypoint at the pressed position, gated on a live connection since saving one means
broadcasting it, and WaypointInfoDialog's onEdit — previously left null — now opens
the editor for unlocked waypoints. rememberWaypointEditing owns the whole lifecycle:
it assigns a packet id and the default pushpin icon to a new waypoint before it goes
on air, exactly as the Google flavour does.

The file had outgrown itself along the way, so the waypoint dialogs now live in their
own component/WaypointDialogs.kt, and the toolbar came out of MapView as MapToolbar,
which owns the filter menu's open state — the shared overlay takes the button and the
dropdown as separate parameters, so something has to hold the flag between them.
FilterMenu resolves its own view model rather than having one forwarded two levels.

MaplibreMap defaults to MapOverlay.Default, which draws a scale bar and a compass
along the top edge plus the logo and attribution along the bottom. The mesh map
already has a compass in its own toolbar — and ours does more, toggling heading-lock
while following — so the library's was a second compass appearing on rotation. The
Google flavour avoids the same collision from the other side with
`compassEnabled = false`.

Supplies MapOverlay.Default minus the compass. The scale bar is kept: it is a control
the OSMdroid map had and the Google one does not, and its units are chosen by region,
matching the locale-driven approach the rest of the app takes via localeUnitsProvider.
The logo and attribution are kept because the styles are licensed on the condition
they are shown — MapOverlay.None would drop them.

Also worth recording from the same audit, since neither is fixable here: the MapLibre
map has no zoom buttons where the Google flavour sets zoomControlsEnabled = true.
maplibre-compose publishes no zoom ornament, and MeshtasticIcons has no minus glyph
among its 210 icons, so closing that needs an icon from meshtastic/design plus
zoom_in/zoom_out strings.

The Google flavour has native +/- buttons via MapUiSettings(zoomControlsEnabled), and
the MapLibre map had nothing — maplibre-compose publishes no zoom ornament, only a
scale bar, compass, logo and attribution. Worst on desktop, where there is no pinch
gesture and no discoverable control at all.

Adds them to the shared toolbar as optional parameters, defaulting to null so the
Google flavour keeps drawing its own and gains nothing here. Zoom steps by one level
and is clamped to MaplibreMap's own 0..20 zoomRange, so pressing at either end stops
rather than animating to a level the map refuses.

Needed a minus glyph: MeshtasticIcons had `Add` but nothing for the other direction
across all 210 icons. ic_remove.xml is the Material Symbols "remove" at the same 960
viewport and rounded weight as the existing ic_add.xml — geometrically the same
horizontal bar with the same rounded caps.

`sitePlannerAvailable()` has returned true on the F-Droid flavour since it was added,
and `SitePlannerLaunch`/`toSitePlannerParams` are both flavour-neutral in
androidApp/src/main — but nothing on that flavour ever called them. The MapLibre
provider hardcoded `onSitePlannerClick = null`, so the button never appeared, and it
ignored the `sitePlannerNodeNum` deep link exactly as it had ignored `waypointId`.

Both are wired. The planner runs through the same host-supplied slot the waypoint
editor uses, since it lives in the app and has no desktop host: the map contributes the
button, the deep link, its centre for the "use map centre" shortcut, and a way to move
itself once coverage is imported. Imported coverage becomes a GeoJSON layer (#6138) and
the map recentres on the transmitter.

One deliberate difference from the Google flavour: no phone-GPS shortcut. Google fills
that from Play Services' fused location, which must not enter an F-Droid build, so the
coordinate fields stay manual with the map centre and the node's own position offered
instead.

…form claims

`:feature:map-maplibre` was the only module in the repo without a README,
which is a poor look for the module this whole change is about. It now has
one: what it renders and where each surface starts, why it is a separate
module rather than source sets in `:feature:map`, what lives in `:feature:map`
instead, and the five things that bite — the glyphs requirement behind the
raster basemaps, Terrarium encoding, offline packs being Android-only,
`mbtiles://` aborting on a missing file, and 0.15.0's broken `drawAsSdf`.

Corrected in the user guide, all of it stale rather than merely thin:

- The layers section said `.kml`/`.kmz` rendering was "temporarily
  unavailable" on Desktop. Desktop has no layer import at all — of any
  format — and the reason is a file picker, not rendering.
- Site Planner said it works on Google Play and F-Droid without mentioning
  that Desktop has neither it nor a WebView to run it in.
- A trailing note repeated both claims less accurately than the sections
  above it, so it is gone.
- The desktop parity table listed Map as full parity. It now says what the
  desktop map does not have, and map layers and Site Planner have their own
  rows.

`sitePlannerAvailable()` existed once per flavor, both returning true, each
with a comment asserting the other flavor returned something different. It
was genuinely flavor-dispatched while only the Google map could draw the
overlay; the F-Droid map has drawn it since earlier in this branch. One
definition in `src/main` now, and the KDoc says why Desktop still gets false.

The localized `docs/<locale>/user/*.md` still describe OSMdroid. Those are
Crowdin output from `docs/en/`, not sources, and regenerate on the next sync.

… for what it tests

`:feature:map`'s README covered the tile catalogue and custom sources but not
the KML converter that moved in beside them.

`KmlToGeoJsonTest` in the F-Droid flavor kept its name after the converter and
all twenty of its behavioural cases moved to common code. What is left tests
`convertKmlSource` — recognising a KMZ, finding the KML inside it, and the
comma-decimal locale — so it is `KmlImportTest`, matching `KmlImport.kt`.

…ay RFC 7946 asks

Two GeoJSON conformance gaps in the KML converter, found by checking the spec
rather than by a report.

A line crossing 180° was emitted as a single LineString, so a two-degree hop
between 179°E and 179°W drew as a line back across every meridian on Earth.
It is now cut into a MultiLineString at the crossing, with the latitude
interpolated along the short way round (RFC 7946 §3.1.9). Polygons are
deliberately left whole: cutting a ring means splitting it into several rings,
and nothing imported here has needed it — noted in the code rather than left
to be discovered.

Exterior rings are now turned counterclockwise (§3.1.6). KML says nothing
about winding and exporters emit both, so the ring is turned rather than
trusted. The existing polygon test happened to use a counterclockwise ring, so
a clockwise one was added to prove the reversal actually happens.

Coordinates are now parsed into a `GeoPosition` and rendered to JSON at the
end, rather than stringified on the way in. Both fixes need the numbers, and
the old shape had thrown them away.

The file split that came with it follows the seam that was already there:
geometry building in `KmlGeometry.kt`, simplestyle and escaping in
`KmlGeoJson.kt`.

`IconStyle` was tracked only so its `<color>` would not be mistaken for the
line colour; the `<Icon><href>` inside it was skipped. It now reaches the
GeoJSON, which is the first half of giving the MapLibre map the icons the
Google map has always drawn.

The reader needed no restructuring: `<Icon>` is not itself a sub-style, so it
falls through without clearing `enclosing`, and the `<href>` inside it still
reads as the IconStyle's. That also keeps `NetworkLink`'s `<Link><href>` from
being mistaken for an icon, since it is never inside an IconStyle — asserted
rather than assumed.

Only points carry it. An icon on a route is noise the renderer would have to
filter out again.

The property is `icon-url`, and it is ours: simplestyle-spec 1.1.0 defines
`marker-symbol` (a fixed icon vocabulary), `marker-color` and `marker-size`,
and nothing for an arbitrary image URL. No later spec has blessed one either —
the modern answer is layer-level styling, which is what the renderer already
does. So the name is declared in one place and documented as an extension
rather than passed off as conformance.

B0 asked whether a packaged distribution can carry JCEF. It cannot: the
JetBrains Runtime the app builds against is the `_jcef` variant and does ship
Chromium, but `packageDistributionForCurrentOS` jlinks a runtime and the
native frameworks are outside the module graph, so they are dropped. Measured:
the bundled runtime is 92 MB against a 631 MB full JBR, and putting Chromium
back would take the application from 218 MB to roughly 757 MB — three and a
half times, per platform, for one feature.

So desktop gets the planner without the embedded browser. The configuration
form is the same `SitePlannerSheet` the Android hosts show, seeded from the
connected radio, with the map centre and the node's own position as shortcuts;
on submit the parameters are encoded into the planner's URL and opened
outside the app.

What desktop does not get is the coverage estimate coming back as a map layer.
That needs a JavaScript bridge, which needs the embedded browser this commit
is avoiding. Stated in the KDoc and in the parity table rather than left for
someone to discover.

`toSitePlannerParams` and `SitePlannerLaunch` moved to `feature/map/commonMain`
unchanged — they were already free of Android types, which is what made the
desktop slot small. The planner URL now has one definition instead of a private
const in the Android runner.

`sitePlannerAvailable()` is gone. It existed to answer a question that now has
the same answer everywhere, and both hosts provide the composition local
directly.

The parity table and the map guide both said desktop had none, which was true
until the previous commit. Both now say it opens in the browser and that the
estimate is not drawn on the desktop map — the part a user would otherwise
discover by running one and looking for it.

… one

`toQueryUrl` always appended `bridge=1`, which tells the Site Planner to hand
its finished estimate to a native host bridge instead of its own share sheet.
That is right for the Android WebView, which implements the bridge. It is
wrong for the desktop hand-off, where the planner runs in an ordinary browser
and there is nothing on the other end.

Found by driving it: the desktop planner opened at
`site.meshtastic.org/?bridge=1` with everything else prefilled and the
simulation already run, which is how a flag meant for an embedded host ends up
in a plain browser tab.

The bridge is now a parameter, defaulting to on so the Android path is
unchanged, and the browser hand-off passes false. `run=1` stays either way.

The Google map has rendered KML icons all along, through maps-utils'
UrlIconProvider. The MapLibre map drew every imported point as a plain
circle — for KML and GeoJSON alike. This adds the symbol layer that closes
that gap.

The renderer has to know a layer's icons before it composes. MapLibre picks
an icon per feature from a `case` over values fixed at build time, and there
is no way to register an image under a name chosen later — `ImageManager`'s
acquire methods are internal to the library. So `CustomLayer` now carries the
set, and the host finds it with `geoJsonIconUrls`.

That scan reads the finished GeoJSON rather than threading the set out of the
KML converter, which is what makes it cover imported GeoJSON too, and what
lets a cached conversion be reused without having to remember its icons. It is
capped at 64 distinct icons: each one becomes a style image held for as long
as the layer is shown, and a file with a per-feature icon would otherwise be
an unbounded upload.

Icons are drawn only once their image has actually loaded, and the circle
layer is filtered to points that are not getting one — so a point never sits
under an empty square while a remote image is in flight, and never keeps a dot
under a drawn icon. A feature whose image fails keeps its plain point.

Not verified on screen. The gate passes and `geoJsonIconUrls` has its own
tests, but seeing an icon drawn needs a real import, and the only host with a
layer importer is Android. A desktop spike could not render an injected test
layer at all — including its plain fill and circle, which are untouched code —
so the harness was as suspect as the feature. Worth an emulator pass with a
KML that names an icon before this is believed.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
This reverts 5f7dc59. It regressed imported point rendering, which is
worse than the gap it was closing.

Verified on an emulator with a seeded KML. The commit before it draws an
imported point; that commit draws none — not the icons, and not the plain
circle for a placemark with no icon at all. Every layer for the source is
registered (the log shows fill, line, point and icon all added, the icon one
about 300ms later as Coil finishes) and the KML converts correctly — the
GeoJSON on the device carries `icon-url` for exactly the three styled
placemarks. So the failure is in the layer's expressions, not the conversion.

The likely cause is one of two things in `ImportedLayer`, neither confirmed:
the `switch` over `icon-url` used as a filter, which excludes every feature
rather than only those without a loaded icon — coalescing the match input to
a string did not fix it — or `rememberLayerIcons` calling `collectAsState`
and `rememberAsyncImagePainter` inside `associateWith`/`filter` lambdas over
a varying set, which is the pattern `rememberChipImages` deliberately avoids
for exactly this reason.

`geoJsonIconUrls` and its tests go with it rather than being left behind
unused; A1's `icon-url` in the converter stays, so the data is still there
when the renderer is rewritten.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Both flavours now parse KML once, in `feature/map`. The Google map hands the
resulting GeoJSON to maps-utils' GeoJSON pipeline instead of asking its
`data.parser` KmlParser to read the file.

That retires a real hazard rather than tidying one. maps-utils' KmlParser and
the app's CoT code shared one resolved xmlutil, and maps-utils 5.0.0 was
compiled against an API xmlutil 1.0.x had removed — so every KML and KMZ
import died with `NoSuchMethodError`, fatal in production across 2.8.0–2.8.1.
A version floor and a canary test were all that held the pairing together.
Neither is load-bearing now: `KmlParser`, `KmzParser` and
`KmlParserLinkageTest` are gone, and the catalog note says why the floor
remains as a plain minimum.

maps-utils' renderer stays — it is what draws on a Google map, and there is no
substitute for it. This removes a second KML parser, not a rendering stack.

`applySimpleStyleSpec` now maps the converter's `icon-url` onto
`PointStyle.iconUrl`. Without it the switch would have been silent data loss:
maps-utils' GeoJSON mapper reads no icon property of its own, so a KML that
draws icons today would have arrived with none. `KmlToGoogleLayerTest` guards
exactly that handover — that maps-utils parses what the converter writes, and
that a placemark's icon survives it — and replaces the canary whose subject no
longer exists.

`KmlImport` moved to `androidApp/src/main`, since both flavours now need the
KMZ sniff.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The previous commit routed Google's KML through the app's converter and lost
something quietly: maps-utils' KML parser used to extract a KMZ's images and
stash them where the renderer's image cache is seeded from, and the GeoJSON
path carries no such thing. A KMZ whose icons live inside the archive — which
is most of them, since that is what KMZ is for — would have drawn none.

`convertKmlSource` now returns the GeoJSON together with any images the
archive held, keyed by their path inside it, which is what a placemark's
`<href>` names and what the cache is keyed by. The Google map puts them back
on the layer, so `UrlIconProvider` resolves an archive-relative href exactly
as before. The zip is walked once; an entry that does not decode as an image
is some other file the exporter packed and is skipped.

`KmlToGoogleLayerTest` grew a case that builds a real KMZ with a packed PNG
and asserts it reaches the renderer's cache — the regression this commit
exists to close, caught by looking for it rather than by a report.

The F-Droid map drops the images for now: its renderer has no icon support
yet, so nothing would read them.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
A KML placemark's `<IconStyle><Icon><href>` — and the `icon-url` an
imported GeoJSON can carry — reached the MapLibre map already, written by
the shared converter, and nothing drew it. Every imported point was the
same blue dot, so an overlay whose whole point was its symbology arrived
unreadable. The Google flavour has honoured these since it moved onto the
shared converter; this closes the gap.

The renderer cannot discover the icons for itself. MapLibre picks an icon
per feature from a `case` over a fixed set of style images, and
`ImageManager`'s acquire methods are library-internal, so there is no way
to register an image under a name chosen later. The host therefore reads
the finished GeoJSON once and hands the layer the set — which also means
an imported GeoJSON naming its own icons is covered, and a cached KML
conversion does not have to remember anything.

The first attempt at this was reverted (3b35a23) for drawing nothing.
The cause was not the expression: Coil decodes to a hardware bitmap by
default on Android, MapLibre rasterizes a style image into a software
canvas, and the app was dying with "Software rendering doesn't support
hardware bitmaps" the moment an icon finished loading — so the map went
with it. `decodeForSoftwareCanvas` is expect/actual because nowhere else
has the notion.

A symbol layer is added over the circle layer rather than replacing it:
an import typically gives icons to a few features and nothing to the
rest, and those still need a dot. The layer is filtered to features whose
icon actually loaded, so a plain point never inherits some other
feature's symbol from the `switch` fallback.

KMZ-packed icons stay unsupported here — their href is a path inside the
archive that nothing can fetch, and those features fall back to a point.
The Google flavour keeps the images and resolves them.

Verified on an emulator: an imported placemark at the Very Large Array
draws its icon, where the parent commit drew a bare dot.
The module READMEs and the developer changelog all stopped at "KML becomes
GeoJSON", which was true until the icons landed. The MapLibre README also
gains the hardware-bitmap trap: it cost a revert, and it presents as an
expression that silently draws nothing rather than as the crash it is.
Desktop cannot import layers, because everything that owns them — the
list, its persistence, the import plumbing — lives in `androidApp` and is
written against `Application`, `Uri` and `ContentResolver`. This is the
half of the fix that has no platform in it. Nothing consumes it yet; the
hosts move over next.

What made it portable is that an import now arrives as a `PickedMapFile`
carrying its own `read: suspend () -> ByteArray?`. Resolving a
`content://` and opening a plain path are both the caller's problem, so
the store keeps one implementation and needs no URI type of its own —
`MapLayerItem.uri` is a plain string, parsed where it is used. Files go
through Okio, network layers through Ktor, and `mapLayersDirectory()` is
expect/actual: app-internal storage on Android, `~/.meshtastic` on
desktop next to the database, Documents on iOS.

`toFileUri` is byte-identical to Android's `Uri.fromFile`, and that is
load-bearing rather than tidy: a layer's URI string is the key its
hidden/shown state persists under, so an installation upgrading onto this
store has to produce the same key for the same file or every layer the
user had hidden comes back visible. Ktor's encoder does the work — it is
already this module's dependency and gets UTF-8 right — but it keeps the
RFC 3986 sub-delimiters that are legal in a path and Android escapes, so
its output is walked once more for those. Tests assert the exact strings
Android writes for spaces, the unreserved set, sub-delimiters, and
non-Latin names.

Read as bytes rather than a stream: a stream has no common type here, and
both readers a layer feeds — the KML converter and the zip reader — want
the whole document anyway.
…ip closes

Desktop had a layers sheet with no way to put anything in it: the sheet,
the picker and the conversion pipeline were all Android code. Now the
whole imported-layer feature is the common store from the previous
commit plus three shared pieces, and desktop mounts the identical UI:

- `rememberMapLayerPicker` is expect/actual in the ExportSaver mould —
  the SAF document picker on Android, an AWT `FileDialog` on desktop
  (the platform's own dialog, as `LogExporter` already chose), a no-op
  on iOS, which has no map host.
- `CustomMapLayersSheet` moved to `feature/map` unchanged — it never
  had an Android import; only its callers did.
- `rememberRenderableLayers` (KML → GeoJSON for the renderer that has
  no KML source, plus the icon scan) moved from the F-Droid source set
  into `feature/map-maplibre`, reading through the store instead of a
  ContentResolver. That swap quietly fixes a real bug: a ContentResolver
  cannot open `http`, so a *network* KML layer on the MapLibre map
  converted to nothing and silently drew nothing. Its KMZ unpacking is
  `readKmlDocument`, duplicated verbatim in androidMain and jvmMain
  rather than shared from a custom source-set group — the hierarchy
  template's group would not attach to the AGP-owned android target,
  and a hand-written dependsOn edge disables the template and silently
  drops iosMain. Twelve lines twice is cheaper than either failure mode.

The "Open in / Send to Meshtastic" intent now hands its file straight
to the store from MainActivity instead of through a one-slot bus only
the Google map drained — so the Site Planner's "Send to App" share now
lands on the F-Droid build too, where it previously did nothing.

This is what makes the desktop Site Planner loop close: the planner
exports a `.geojson`, and the same host can now import it. The sheet
note, the user docs and the browser-sheet KDoc all said desktop could
not — flipped.

Storage compatibility is deliberate, not incidental: the Android actual
resolves to the same `filesDir/map_layers` the old manager wrote, and
file URIs byte-match `Uri.fromFile`, so existing imports and their
hidden/shown state survive the upgrade.

Verified live on both hosts. Desktop (driven through the hot-reload MCP
server's semantic tree): a planner-shaped GeoJSON in `~/.meshtastic/
map_layers` loads on start, draws at its bounds with its simplestyle
colours, lists in the sheet, and hides and returns with the eye toggle.
The native file dialog itself was not driven — it is the one part with
no semantics to reach. F-Droid (emulator): a KML imported before this
change still lists and still draws its icons after upgrading onto the
common store.
A KMZ of georeferenced image tiles — an ESRI topo export, aerial
imagery — parsed, produced a layer with nothing in it, and drew nothing.
#3786 asked for exactly this and was closed by the stale bot.

The converter now reads `<GroundOverlay>` alongside the placemarks and
returns them from `convertDocument` beside the GeoJSON, because an image
draped over a box has no GeoJSON representation at all. An overlay-only
document is no longer "nothing mappable". The box corners — with the
optional `<rotation>`, degrees counter-clockwise about the centre per
the KML reference — are computed by `corners()` next to the parser,
where they are tested; rotation happens in a locally-scaled frame so a
rotated box keeps its shape on the ground instead of shearing with
latitude.

MapLibre drapes each overlay as an `ImageSource` quad under a
`RasterLayer`, below the layer's own vector features — a ground overlay
is a basemap-like backdrop, not a marker. Images are extracted from the
archive into the conversion cache, and the corner data goes into a
sidecar file the cache hit reads back: the GeoJSON cannot carry it, and
reconverting on every launch would defeat the cache. The Google map
drapes through `GroundOverlayOptions` from bounds, bearing set to the
negated rotation (bearing is clockwise), images resolved from the same
packed-image map its placemark icons already use.

An href that is not packed in the archive is logged and skipped rather
than draped broken — above all the Site Planner's KML export, whose href
names a sibling file that was never in an archive. Making that export
round-trip needs the planner to emit a KMZ, which is an upstream change
in meshtastic-site-planner.

Verified live where a basemap exists to verify against: on desktop and
on the F-Droid emulator, a hand-built KMZ drapes an
orientation-revealing image exactly inside its LatLonBox, right side up,
with a placemark from the same document pinned to the image's top-left
corner. The Google flavour imports the same KMZ and runs its drape path
without error, but a debug build carries a placeholder Maps key, so its
basemap is blank and the drape could not be visually placed — the code
path is the one Google documents for exactly this, and the shared corner
math is the tested, twice-verified part.

Closes #3786.
`GroundOverlayLayer` decoded its image inside `remember`, which runs
during composition on the UI thread. The verification image was 190 KB
and never showed it, but the feature exists for ESRI exports whose tiles
are routinely multi-megapixel — a few hundred milliseconds of
synchronous decode per overlay, hitching the map on its first
composition. `produceState` moves the decode to the IO dispatcher; the
overlay simply appears a frame later.

Also: a cache hit now verifies the extracted overlay images still exist
before trusting the sidecar. Android may clear individual cache files,
and a sidecar pointing at deleted images would drape nothing until a
manual refresh; now that state reconverts instead.
…alidates

The persisted record for a network layer is id|name|url — no type — and
rehydration hardcoded KML while addNetworkMapLayer inferred GEOJSON from
the URL. A network GeoJSON layer therefore worked until the next launch,
then went through the XML parser and silently drew nothing. Both paths
now derive the type from one helper, so they cannot disagree.

The add dialog also validates before confirming. The store already
returned an error string, but two of its three callers (the F-Droid
view model and the shared ImportedLayersSlot) drop it, so a bad URL
closed the dialog with nothing added and nothing said. The dialog now
mirrors the store's rules — non-blank name, explicit http(s) scheme —
with field errors, and keeps its input across recreation. The scheme
check is on the string: Ktor's Url() defaults a missing scheme to http,
which would validate a URL nothing can later fetch.

All three KMZ readers ran zip.readBytes() with no bound, and a zip's
inflated size is unrelated to its size on disk — a small hostile file
arriving through share-into-app could OOM the app. The OSMdroid
renderer this branch deletes capped the same read at 50 MB; that cap
is back, shared by the platform readers and the Google flavour's
importer, and enforced on the bytes actually produced rather than the
entry header a hostile zip lies in. A blown budget skips the entry:
the document read refuses the file, the image reads keep what was
already extracted and let the rest be skipped as "not packed".

Covered by a new jvmTest suite (the androidMain twin is a verbatim
copy) including a deflated-zeros bomb.

readSimpleElement() throws on the first child element, and a KML
<description> legitimately holds HTML — usually CDATA-wrapped, but raw
nested markup is valid XML too, and one such description aborted the
whole document. Descriptions now read through a tolerant helper that
keeps the character content and skips the markup.

A download box straddling ±180° arrives with west > east, so its
column span went negative and the whole estimate was nonsense. The
columns now wrap around the tile grid.

supercluster excludes every visited point from later neighbourhoods,
clustered or not; this port only retired clustered ones. A node
already emitted as standing alone could then be counted into a later
cluster, padding it up to the minimum and wrongly folding that
cluster's centre in — which cost the centre its chip.

- MeshMap frames the mesh from a LaunchedEffect gated on the viewport,
  as FitBoundsOnceVisible already did: a launch from the composition
  body fires even when the composition is abandoned, and a fit before
  the map reports a viewport lands on a default.
- The mesh-wide visibility filter is remembered instead of re-running
  on every camera-frame recomposition.
- A ground-overlay decode uses safeCatching, as the rest of the
  conversion path does, so cancellation propagates.
- Icons are scanned for any layer whose document is a local file —
  which a converted network KML's is — instead of skipping every
  network layer.
- A ground overlay's href-derived cache extension is sanitized; a '/'
  in it failed the write and cost the import.
- The node track screen composes only once its node resolves, rather
  than painting the track under node number 0.
- The track point card omits the altitude row when none was reported,
  the pack label rounds instead of truncating, the layers manager logs
  rejected user input at warning, EditWaypointDialog's caller modifier
  lands only on the dialog root (it also reached the inner column),
  the offline sheet's zoom-range label is a string resource, and the
  map-layer tests delete their temp directories.

desktop.md still said layer import "needs a file picker desktop does
not have yet"; the feature shipped on this branch, and
map-and-waypoints.md already said so. The feature table and the known
limitations now agree.

Also retires the KDocs the same work left behind — NodeChipLayer's
visibleBounds parameter that moved to NodeLayers, the provider slots
that claimed desktop passes none of them, waypoint icons "drawn
through a text field" (they are image-per-glyph), an OSMdroid
reference, and a pulse constant documented with its neighbour's
meaning — and rejoins comment lines spotless had wrapped mid-sentence.

…w's date-line stance

Nothing in "(z10–19)" translates, so keep it out of Crowdin; and give
nodesInView the same one-line antimeridian note MapBounds carries, since
they share the deliberate linear treatment.
