James Rich 4aba9cd3e9 test: pin ModemPreset->channel-name contract; drop vacuous name check
Add ChannelPresetNameTest (commonTest, so it gates every PR) pinning
every ModemPreset to its exact firmware-canonical channel name from
DisplayFormatters::getModemPresetDisplayName(preset, useShortName=false).
The name is interop-critical (it feeds the channel hash, channel
number/frequency and MQTT topic), so the test:
- locks the mapping against accidental edits (e.g. "LongMod" ->
  "LongModerate"),
- asserts set-completeness vs ModemPreset.entries, so a new preset that
  was added to Channel.name's `when` but not pinned here fails loudly
  (also catches someone silencing the intentional compile tripwire with
  an `else`),
- covers the deprecated VERY_LONG_SLOW, which still has a real name.

This backstops Channel.name's exhaustive `when` without weakening it.
The numeric on-air anchors (hash/channelNum/radioFreq) stay in
ChannelTest. Remove the old androidDeviceTest allModemPresetsHaveValidNames,
which only asserted name != "Invalid" — a value the no-else `when` can
never produce, so it gave the illusion of a name guard while testing
nothing, and ran only on-device rather than on every PR.

:core:model (Meshtastic Domain Models)

Overview

The :core:model module is a Kotlin Multiplatform (KMP) library containing the domain models and data classes used throughout the application and its API. These models are platform-agnostic and designed to be shared across Android, JVM, and future supported platforms.

Multiplatform Support

Models in this module use the CommonParcelable and CommonParcelize abstractions from :core:common. This allows them to maintain Android Parcelable compatibility (via @Parcelize) while residing in commonMain and remaining accessible to non-Android targets.

Key Models

  • DataPacket: Represents a mesh packet (text, telemetry, etc.).
  • NodeInfo: Contains detailed information about a node (position, SNR, battery, etc.).
  • DeviceHardware: Represents supported Meshtastic hardware devices and their capabilities.
  • Channel: Represents a mesh channel configuration.

Usage

This module is a core dependency of core:api and most feature modules.

// In commonMain
implementation(projects.core.model)

Structure

  • commonMain: Contains the majority of domain models and logic.
  • androidMain: Contains Android-specific utilities and implementations for expect declarations.
  • androidUnitTest: Contains unit tests that require Android-specific features (like Parcel testing via Robolectric).
